As AI developer tools become part of everyday development, improving the accuracy of generated code has become just as important as generating it quickly.

AI coding assistants can generate a form, dashboard, or data grid in seconds. The initial results often look impressive, but developers quickly discover that generating code is only part of the job.

When working with a component library such as Syncfusion, small implementation details matter. Missing imports, incorrect configuration, outdated APIs, or overlooked dependencies can turn a seemingly complete solution into a debugging session.

This is especially true when building applications with feature-rich UI components. An AI coding assistant might know how to create a grid, chart, or scheduler, but it doesn’t always know the recommended way to implement those components within a specific ecosystem.

To help bridge that gap, Syncfusion provides two AI coding assistant tools:

• Agent Skills: Provide component-specific implementation knowledge directly to the AI coding assistant.
• MCP Server: Gives AI coding assistants access to Syncfusion’s latest documentation, APIs, and code examples.

Together, they help reduce manual fixes and make AI-assisted development more reliable.

Why AI-generated component code still needs manual fixes

Modern AI coding assistants are excellent at understanding programming concepts and generating working code. However, component libraries introduce an additional layer of complexity that generic AI models don’t always have access to.

When generating code for a UI component, the assistant may need to understand:

• Component-specific APIs,
• Required modules and dependencies,
• Recommended configuration patterns,
• Accessibility considerations,
• Framework-specific implementation details, and
• Recently introduced features and updates.

Without that context, generated code can be incomplete or based on outdated examples.

For example, imagine prompting an AI assistant to:

Create a Syncfusion DataGrid with paging, sorting, filtering, and Excel export enabled.

The generated code may render successfully, but developers often encounter issues such as:

• Missing service injections,
• Incorrect export configuration,
• Required modules not being included,
• Deprecated APIs, and
• Additional manual cleanup before deployment.

The challenge isn’t that the AI can’t build a grid. The challenge is ensuring it builds a Syncfusion Grid using the recommended implementation approach.

That’s the problem the Syncfusion AI coding assistant tools aim to solve.

Agent Skills: Write Syncfusion components the right way

Agent Skills are installable project-level guidance packages centered around SKILL.md instructions that AI coding assistants can use during development.

Each skill captures the recommended implementation patterns for a Syncfusion component, including:

• Setup,
• Required modules,
• Properties,
• Events,
• Theming, and
• Accessibility guidance.

Whenever your AI coding assistant is about to generate or modify Syncfusion code, it consults the relevant skill and follows those patterns.

The result is code that is more likely to follow established Syncfusion patterns, including the appropriate modules, feature configuration, theming guidance, and current recommended APIs. It’s especially handy for teams that want every developer, and every prompt, to stay on the same page by default.

For example, when asked to create a Syncfusion DataGrid with sorting and filtering enabled, an AI coding assistant using Agent Skills automatically includes the required modules and feature configuration instead of generating incomplete boilerplate code.

MCP Server: Get answers directly from Syncfusion documentation‌

Even with implementation guidance, developers regularly run into questions that require up-to-date information.

They might need to:

• Explore a newly released feature,
• Verify an API change,
• Troubleshoot an unexpected behavior,
• Review advanced implementation examples, and
• Check the updated documentation.

This is where MCP Server becomes valuable.

The MCP Server allows AI coding assistants to retrieve information directly from Syncfusion documentation through the #search_docs tool.

Rather than relying entirely on model training data, your assistant can query current documentation and return relevant guidance while you’re working in your editor.

For example, if you’re configuring Excel export for a Grid component, the assistant can pull the latest implementation guidance from the documentation instead of relying on potentially outdated examples.

It runs locally and works in any MCP-compatible editor: VS Code, Syncfusion Code Studio, Cursor, JetBrains, and more. It also works across the full range of components and SDKs available in Syncfusion Essential Studio.

This helps reduce context switching and minimizes the need to manually search through documentation while developing.

Important note: For active Syncfusion users, access is unlimited and privacy-first: your requests are not used for model training.

A real-world example: Building an internal dashboard

Consider a developer building an internal reporting dashboard that includes:

• DataGrid filtering and sorting,
• Excel export functionality,
• Interactive charts, and
• Scheduling components.

An AI coding assistant can generate much of the initial implementation quickly. However, issues often appear during integration:

• A required module is missing.
• An export feature isn’t configured correctly.
• A recently updated API behaves differently than expected.

In this scenario:

• Agent Skills help generate code using recommended implementation patterns from the beginning.
• MCP Server provides current reference information when questions arise during development.

Instead of switching between generated code, documentation pages, and troubleshooting articles, developers can stay focused on building features.

Which tool should you use?

Not sure where to begin? Here’s a quick way to match each tool to what you’re doing.

A better development experience when used together

Each tool solves a different problem.

Agent Skills improve code generation by giving AI assistants implementation guidance. MCP Server complements that by providing access to Syncfusion’s documentation and reference material whenever additional context is needed.

A typical development process might look like this:

1. Use Agent Skills to generate an initial implementation.
2. Build and iterate on the feature.
3. Use MCP Server whenever you need documentation, API details, or troubleshooting help.
4. Refine and validate the implementation before deployment.

The result is a development experience with fewer interruptions, fewer manual corrections, and greater confidence in the generated output.

MySQL and PostgreSQL both store spatial and geometric data, but they take fundamentally different approaches. While MySQL bakes spatial support directly into its engine, PostgreSQL separates two ecosystems: native geometric types (built-in, flat-plane, non-geographic), and PostGIS (a full GIS extension with coordinate systems, projections, and hundreds of spatial functions).

For most real-world location-aware applications — GPS tracking, geofencing, distance queries — PostGIS is the more powerful option, though MySQL 8.0 closed the gap considerably for common use cases. This guide compares their architectures, data types, indexing strategies, spatial functions, and what to watch out for if you’re migrating between them.

Why is spatial and geometric data so important?

Every time you open Google Maps, request an Uber, track a delivery package, search for nearby restaurants, or see weather activity displayed on a map, spatial data is working behind the scenes. This is because modern applications no longer deal with just text, numbers, and dates – they increasingly need to understand location, distance, boundaries, routes and geographic relationships as well.

For example, a food delivery app needs to determine which rider is closest to a customer, and a logistics company may need to optimize delivery routes across multiple cities. Traditional data types can’t handle these kinds of operations efficiently, which is where spatial and geometric data types come in.

Both MySQL and PostgreSQL provide support for storing and querying geometric and geographic data, but they approach the problem very differently. MySQL includes spatial functionality directly within its engine, while PostgreSQL splits its capabilities between native geometric data types and the far more advanced PostGIS extension.

Why this distinction matters more than you may realize

MySQL and PostgreSQL both support concepts like points, polygons, lines, and spatial indexing. However, once you start working with coordinate systems, the architectural differences become much more obvious. These systems include SRIDs, GIS functions, earth-based calculations, and migration scenarios.

Even the terminology differs. MySQL primarily refers to these features as spatial data types, while PostgreSQL distinguishes between built-in geometric types and PostGIS spatial types. These differences affect everything – from indexing and query performance, to data validation and migration complexity.

Spatial and geometric data in databases – an overview

Traditional relational databases can store latitude and longitude as plain numeric columns, like so:

latitude DECIMAL(10,8)
longitude DECIMAL(11,8)

This approach becomes limiting when applications need to perform functions like finding nearby locations, calculate distances, and determine whether a point falls inside a region. Spacial data types solve these problems by treating location data as first-class objects.

MySQL and PostgreSQL both implement geometry models largely inspired by OGC (Open Geospatial Consortium) standards. Here are some common spatial types used in both systems:

The spatial data type in MySQL

Spatial support is built directly into MySQL. It implements spatial extensions internally and supports geometry storage, spatial indexes, and spatial functions natively.

A typical spatial column looks like this:

CREATE TABLE stores (
    id INT PRIMARY KEY,
    location POINT SRID 4326
);

MySQL stores geometry data in its own internal binary format consisting of a 4-byte SRID (Spatial Reference System) prefix, followed by standard OGC WKB (Well-Known Binary) data. It fully supports exchanging this data using OGC-compliant formats including WKT (Well-Known Text), standard WKB, and SRIDs.

For example, a location can be represented in WKT as:

POINT(3.3792 6.5244)

This human-readable format is commonly used for inserting or debugging spatial data. You can store it in MySQL using:

INSERT INTO locations (geom)
VALUES (
    ST_GeomFromText(
        'POINT(3.3792 6.5244)',
        4326
    )
);

In this example, POINT(3.3792 6.5244) is the WKT representation, and 4326 is the SRID. It refers to the widely-used World Geodetic System (WGS), an 84-coordinate system used by GPS and mapping systems. Internally, MySQL converts this into binary geometry data for efficient storage and indexing. The same geometry can also be represented using WKB, the compact binary equivalent of WKT.

Unlike WKT, WKB is not human-readable. Instead, it’s designed for efficient machine processing and data exchange between GIS systems.

MySQL also provides functions for converting between these representations:

SELECT ST_AsText(geom)
FROM locations;

returns:

POINT(3.3792 6.5244)

while:

SELECT ST_AsBinary(geom)
FROM locations;

returns the WKB representation of the geometry.

Leaving out the SRID when creating a spatial object causes MySQL to apply a default value of 0. This specific identifier treats your data as coordinates on a completely flat, infinite Cartesian grid. On this grid, your numbers are just random (X) and (Y) points on an infinite sheet of graph paper. MySQL has no clue if those numbers mean miles, meters, or degrees. It also completely loses track of the fact that the Earth is round!

Improvements made in MySQL 8.0

MySQL 8.0 significantly expanded its spatial capabilities and introduced several new GIS functions that made spatial operations more practical for real-world geographic applications. Earlier MySQL versions already supported core geometry operations, but 8.0 improved standards compliance, SRID awareness, coordinate handling, validation, and geographic calculations.

Importantly, it also added ST_Latitude(), ST_Longitude(), ST_SwapXY() and ST_Transform(). ST_Latitude() and ST_Longitude() were added specifically for geographic coordinate systems and provide a clearer alternative to the older ST_X() and ST_Y() functions. Before MySQL 8.0, developers commonly extracted coordinates using:

SELECT ST_X(location), ST_Y(location)
FROM places;

The problem is that ST_X() and ST_Y() only return the first and second coordinate axes. They do not explicitly indicate whether the values represent longitude or latitude. This often caused confusion in GIS applications, especially when developers accidentally reversed coordinate ordering.

Thankfully, MySQL 8.0 introduced clearer geographic semantics:

SET @pt = ST_GeomFromText(
    'POINT(3.3792 6.5244)',
    4326
);

SELECT
    ST_Longitude(@pt),
    ST_Latitude(@pt);

These functions work specifically with geographic SRS’ such as SRID 4326 (WGS 84). If the geometry does not use a geographic SRS, MySQL raises an error.

Version 8.0 also added stricter coordinate validation. Longitude values outside (-180, 180], and latitude values outside [-90, 90], now generate errors for geographic coordinates.

For example:

SELECT ST_Latitude(
    ST_GeomFromText(
        'POINT(3.3792 120)',
        4326
    )
);

…produces a latitude out-of-range error because latitude cannot exceed 90 degrees.

Another major improvement was the addition of ST_Transform() in MySQL 8.0.13, allowing coordinate transformations between SRS’:

SELECT ST_AsText(
    ST_Transform(
        ST_GeomFromText(
            'POINT(3.3792 6.5244)',
            4326
        ),
        3857
    )
);

This converts coordinates from the WGS 84 geographic coordinate system (4326), into the Web Mercator projection (3857) commonly used in web mapping systems.

MySQL 8.0 also introduced newer analytical spatial functions, such as:

For example, ST_AsGeoJSON() became extremely useful for modern web applications because JavaScript mapping libraries, such as Leaflet and Mapbox, commonly use GeoJSON.

SELECT ST_AsGeoJSON(
    ST_GeomFromText(
        'POINT(3.3792 6.5244)',
        4326
    )
);

Result of the above: {"type":"Point","coordinates":[3.3792,6.5244]}

These additions show how MySQL 8.0 moved beyond basic geometric storage and more toward mature GIS-oriented functionality.

The PostgreSQL geometry data type

Before discussing PostgreSQL’s advanced spatial capabilities (PostGIS), it’s important to understand that PostgreSQL already includes its own native geometric type system directly within its core engine. These built-in geometric types have existed in PostgreSQL for decades and are completely separate from the PostGIS extension.

This distinction is extremely important – many developers mistakenly assume PostgreSQL’s native geometric types are the same as PostGIS geometry types, but this is not the case.

PostgreSQL geometric types explained

PostgreSQL geometric types are primarily designed for representing two-dimensional planar objects and performing mathematical geometry operations inside the database. They work well for applications involving shapes, coordinates, computer graphics, engineering calculations, computer-aided design (CAD) style systems, or simpler spatial computations.

However, they are not full GIS types, so don’t provide advanced geographic capabilities such as SRIDs, Earth projections, coordinate transformations, or geospatial standards compliance that PostGIS introduces later.

PostgreSQL provides several native geometry types, which are:

These types internally store coordinates using double precision floating-point values.

The PostgreSQL point type

The point type is the foundation of PostgreSQL’s geometric system. It stores a simple (x,y) coordinate pair:

CREATE TABLE locations (
    id SERIAL PRIMARY KEY,
    coordinates POINT
);

Example insertion:

INSERT INTO locations (coordinates)
VALUES ('(3.3792,6.5244)');

You can query it directly:

SELECT coordinates
FROM locations;

Result: (3.3792,6.5244)

Unlike PostGIS geometry objects, PostgreSQL’s native point type has no SRID awareness, no coordinate system metadata, no Earth projection support, and no GIS validation rules. It simply represents mathematical coordinates on a flat plane.

The PostgreSQL line type

The line type represents an infinite line extending endlessly in both directions. PostgreSQL stores it using:

CREATE TABLE routes (
    id SERIAL PRIMARY KEY,
    route LINE
);

And PostgreSQL inserts it using two points:

INSERT INTO routes (route)
VALUES ('((0,0),(5,5))');

Infinite lines are rarely used in GIS systems but can be useful in engineering calculations, geometry simulations, and mathematical modeling.

The PostgreSQL lseg type

lseg stands for “line segment.” Unlike line, this type stores a finite segment between two endpoints. For example:

CREATE TABLE roads (
    id SERIAL PRIMARY KEY,
    segment LSEG
);

Insert:

INSERT INTO roads (segment)
VALUES ('[(0,0),(10,10)]');

This is useful for road fragments, vectors, edges in graph systems, and engineering diagrams.

The PostgreSQL box type

The box type represents rectangular regions using two opposite corners. For example:

CREATE TABLE regions (
    id SERIAL PRIMARY KEY,
    area BOX
);

Inserting data:

INSERT INTO regions (area)
VALUES ('((0,0),(10,10))');

Internally, PostgreSQL automatically normalizes the coordinates to store the upper-right corner and lower-left corner.

The PostgreSQL path type

The path type represents connected sequences of points. PostgreSQL supports both open paths and closed paths.

Open path example: '[(0,0),(5,5),(10,0)]'

Closed path example: '((0,0),(5,5),(10,0))'

Notice the syntax difference between the two: square brackets [] are used for open path, while parentheses () are used for closed path.

This type is useful for movement tracking, routing simulations, vector graphics, and navigation paths.

The PostgreSQL polygon type

polygon represents closed geometric areas. For example:

CREATE TABLE zones (
    id SERIAL PRIMARY KEY,
    boundary POLYGON
);

Inserting data:

INSERT INTO zones (boundary)
VALUES (
    '((0,0),(10,0),(10,10),(0,10))'
);

Polygons are very similar to closed paths but PostgreSQL treats them differently, providing specialized polygon operators. This type works well for geometric regions, shape analysis, and planar containment tests. However, unlike PostGIS polygons, there’s no SRID support, no spherical geometry, and no coordinate transformation system.

The PostgreSQL circle type

The circle type stores center point and radius. For example:

CREATE TABLE radar (
    id SERIAL PRIMARY KEY,
    coverage CIRCLE
);

Inserting data:

INSERT INTO radar (coverage)
VALUES ('<(5,5),10>');

This represents:

center = (5,5)
radius = 10

Circles are useful for radius searches, proximity checks, simulation systems, and geometric computations.

What are the limitations of built-in geometric types in PostgreSQL?

Despite being useful, PostgreSQL geometric types have important limitations. Most significantly, they are fundamentally planar, mathematical, and non-geographic. They do NOT support the following:

For example, point '(3.3792,6.5244)' is simply treated as:

x = 3.3792
y = 6.5244

PostgreSQL does not know these represent GPS coordinates (longitude and latitude). This is a major architectural difference compared to PostGIS.

Introducing PostGIS

As geospatial applications became more sophisticated, PostgreSQL’s built-in geometric system was no longer sufficient for enterprise GIS workloads. Applications increasingly needed:

This is where PostGIS entered the picture. PostGIS extends PostgreSQL with fully GIS-aware spatial types such as geometry and geography – alongside hundreds of advanced spatial functions, coordinate transformation systems, and enterprise GIS capabilities.

This means PostgreSQL effectively has two different geometry ecosystems: the native geometric types built into PostgreSQL itself, and the advanced GIS-oriented spatial types provided by PostGIS.

In many ways, PostGIS is what elevated PostgreSQL into one of the most widely used spatial databases in the world.

What support does the PostGIS PostgreSQL extension add?

More specifically, PostGIS is an extension that adds spatial object support, spatial indexing, geographic calculations, raster processing, topology features, coordinate transformation systems, and hundreds of GIS functions to PostgreSQL.

Unlike MySQL, where spatial support is built directly into the core database engine, PostgreSQL separates advanced geospatial functionality into an extension architecture.

PostGIS is enabled using CREATE EXTENSION postgis;. Once installed, PostgreSQL gains entirely new spatial data types, operators, indexing strategies, GIS functions, projection systems, and interoperability features. This modular design is one reason PostgreSQL is highly extensible.

The PostGIS geometry type

The geometry type is the most commonly used PostGIS type. It stores spatial objects on a flat Cartesian coordinate plane. For example:

CREATE TABLE stores (
    id SERIAL PRIMARY KEY,
    location geometry(Point, 4326)
);

This definition contains several important components, such as:
i. Geometry (PostGIS spatial type)
ii. Point (geometry subtype)
iii. 4326 (SRID)

Unlike PostgreSQL native geometric types, PostGIS geometries are SRID-aware. The SRID identifies the coordinate reference system used by the geometry, meaning PostGIS understands that coordinates represent longitude, latitude, and geographic positioning rather than just arbitrary mathematical coordinates.

This distinction changes everything about distance calculations, indexing, coordinate transformations, projections, and GIS interoperability.

The geography type in PostGIS

One of PostGIS’s most important innovations is the geography type. Compared to geometry, which assumes a flat plane, geography performs calculations on a spheroidal Earth model – important because, of course, Earth is not flat.

For example:

CREATE TABLE airports (
    id SERIAL PRIMARY KEY,
    location geography(Point, 4326)
);

If we want to calculate the distance between Lagos and London, using planar geometry calculations may produce distorted results simply because the Earth curves. The geography type accounts for this with earth curvature, spherical calculations, and geodesic distances. This makes it ideal for GPS systems, airline routing, shipping systems, and global mapping applications.

Here’s an outline of the geometry vs geography tradeoff:

PostGIS’ massive spatial function ecosystem

Another reason PostGIS dominates GIS workloads is its enormous function ecosystem. PostGIS provides hundreds of spatial functions. Let’s go over some of the common ones.

Geometry construction functions in PostGIS

For example, the ST_MakePoint() function creates a spatial point from the coordinate values
SELECT ST_MakePoint(3.3792,6.5244);, giving the result POINT(3.3792 6.5244).

In most real-world applications, developers usually assign an SRID immediately after creating the point:

SELECT ST_SetSRID(
    ST_MakePoint(3.3792, 6.5244),
    4326
);

However, that’s not needed here, as ST_MakePoint() creates the geometry while ST_SetSRID() assigns the WGS 84 coordinate system (4326).

Output and conversion functions in PostGIS

An example using the ST_AsGeoJSON() function:

SELECT ST_AsGeoJSON(
    ST_SetSRID(
        ST_MakePoint(3.3792, 6.5244),
        4326
    )
);

The ST_AsGeoJSON() function converts spatial data into GeoJSON format, which is commonly used by mapping libraries such as Leaflet, OpenLayers, and Mapbox.

Result:

{
"type": "Point",
"coordinates": [3.3792, 6.5244] }

This makes PostGIS highly suitable for APIs and frontend GIS applications.

Spatial relationship functions in PostGIS

Another powerful feature of PostGIS is spatial relationship analysis, summarized as so:

The ST_Contains() function checks whether one geometry completely contains another. For example:

SELECT ST_Contains(
    ST_GeomFromText(
        'POLYGON((0 0, 10 0, 10 10, 0 10, 0 0))',
        4326
    ),
    
    ST_GeomFromText(
        'POINT(5 5)',
        4326
    )
);

This query checks whether the polygon contains the point (5,5). Functions like ST_Contains() are widely used for geofencing, delivery zones, and more.

Distance and measurement functions in PostGIS

One of the most heavily used PostGIS capabilities is spatial distance calculation. The functions include:

The ST_Distance() function calculates the distance between two geometries. For example:

SELECT ST_Distance(
ST_SetSRID(
ST_MakePoint(3.3792, 6.5244),
4326
)::geography,
ST_SetSRID(
ST_MakePoint(3.4219, 6.4433),
4326
)::geography
);

In this query, both points are converted to the geography type, and PostGIS performs Earth-aware distance calculations. This functionality is commonly used in ride-sharing applications, delivery systems, nearby searches, etc.

What other capabilities does PostGIS provide?

Beyond basic geometry operations, PostGIS also provides several advanced GIS capabilities that distinguish it from simpler spatial database systems. These include:

These capabilities are one reason PostGIS is commonly used in enterprise GIS systems, scientific research, mapping infrastructure, environmental monitoring, and large-scale geospatial analytics.

MySQL vs PostgreSQL spatial and geometric data types: the key takeaways

A major migration takeaway is that PostgreSQL’s native geometric types are not equivalent to MySQL spatial types. For most GIS-oriented migrations, PostGIS is usually the proper migration target – not PostgreSQL’s built-in geometric system.

Another important difference is SRID handling. PostGIS enforces much stricter coordinate systems and geometry validation than in MySQL which, as a result, often exposes hidden issues such as invalid geometries, inconsistent SRIDs, or improperly formatted spatial data during migration.

Teams migrating from MySQL also need to understand the distinction between PostGIS geometry and geography types. Choosing the wrong type can affect distance calculations, indexing behavior, accuracy, and query performance.

Finally, while PostGIS still offers a much larger spatial ecosystem, MySQL 8.0 greatly improved developer experience for applications involving GPS coordinates, mapping systems, routing, geofencing, and location-aware services.

The post MySQL vs PostgreSQL: spatial data types, functions, and migration pitfalls explained appeared first on Simple Talk.

When a FHIR deployment goes wrong, the failure usually traces back to something decided, or not decided, before any software was installed.

Security wasn’t brought in until the design was already done. Nobody asked how many requests production would actually see. Nobody asked whether the FHIR server would be the source of truth or just a synced copy, and that single question ends up shaping half the architecture.

This is essentially the conversation we have with every customer before anything gets built, generalized enough that any team can run it themselves.

It has less to do with technology than you’d think. The most important thing is getting the right people in the room early and asking a short list of questions whose answers determine everything else.

Who needs to be in the room

Who you get in the room matters more than which reference architecture you pick.

In practice that looks like:

• Project Manager: manages requirements and timelines; ideally someone who understands FHIR.

• Lead Architect: owns the overall design, networking, deployment, security posture, and integration strategy.

• Software and Integration Engineers: connect and map source data, secure the environment, manage traffic, and implement custom business rules.

• Compliance: knows which regulations and implementation guides apply, along with their deadlines.

• Subject Matter Experts: FHIR specialists and health system analysts who know the underlying data and can navigate terminologies like SNOMED, ICD-10, LOINC, and other value sets and coding systems FHIR relies on.

• Data Security: responsible for ensuring no one accesses PHI who shouldn’t. This role can slow a project down, but that’s not a knock against it, just something to plan for. Security approval is usually the hardest to get, given the PHI and HIPAA risk involved. The best thing you can do for your timeline is bring security in on day one, rather than discovering their requirements at the end.

Some organizations cover all of these roles with two people. Others need a full team per function. The roles matter, not the headcount.

The questions that decide the architecture

A handful of questions, asked honestly, do most of the planning work.

Which implementation guides do you need to support? That decides your conformance resources: custom search parameters, profiles, code systems, value sets, and for quality use cases, measures and libraries.

How many requests will production actually see? The honest range runs from a few requests a month for a compliance-only deployment to thousands of requests per second when the FHIR server is the central interoperability layer for seven or eight applications. Those are different architectures. It’s also important to plan for potential growth in use over the next few years. If it’s possible that use could grow quickly, plan a scalable platform from the beginning.

How much data? Thousands of resources sit fine in a simple database and basic FHIR server, but millions/billions change your storage, indexing, and loading strategy.

Is the API public or secured? Public endpoints change your threat model completely. Public APIs are where it gets scary, because anyone who knows the endpoint can hit it. In practice, it’s often the provider directory, the least sensitive data you host, that draws the most traffic, including the app that re-downloads everything every 30 seconds. That’s what rate limiting with a proxy service is for.

Do you need validation in production? Validation is expensive to run in the request pipeline. If outside parties write to your server, you likely need it there, along with a plan for handling failures: either reject invalid data strictly or admit it while flagging it for review. Either way, you need somewhere for failed messages to land, since not everyone using your API knows how to interpret an OperationOutcome.

If only your own internal pipeline writes to the server, validate earlier in that pipeline instead, before data reaches the server. One advantage: validation scales out well. Since it barely touches the database layer, you can place multiple validating servers/services in front of your main server to handle the load.

Source of truth or sync target?

One question decides your backup strategy, your availability requirements, and a chunk of your cost: Is the FHIR server the system of record, or a synchronized copy?

If it’s the source of truth, back it up like the transactional system it is. If it’s not, backing up billions of resources is an expensive way to protect data that already lives somewhere else. You might be better off reloading from source using your staging area and a last-updated window. Knowing which one you’re dealing with changes how much high-availability you buy and how much disaster recovery you build into the system.

The same logic applies to deployment. Cloud gives you scaling, geographic redundancy, and low upfront cost, and it’s the default preference for me. But regulation and data residency can override that, and costs are hard to predict until it’s running. On-premises trades capital cost and dedicated system engineers for control. A hybrid setup, data on-premises with compute in the cloud over a secure pipe, is often the workable middle ground.

Portability matters too. Whatever you choose, you want the option to move it later without a rebuild, since regulation, cost, or a platform migration can force that decision for you.

Access and identity

Almost every FHIR server sits behind a proxy service to direct traffic, reroute during upgrades, and rate-limit clients that misbehave. Behind that, SMART on FHIR, built on OAuth2, is the standard for authorizing clients, with your identity provider (Microsoft Entra ID, Okta, Keycloak, AWS Cognito) federated via OpenID Connect or SAML.

Here’s the catch: off-the-shelf identity providers aren’t SMART-aware. Entra ID, for example, wants to issue roles, not scopes, and has no idea which patient resource a logged-in user maps to. Something must own that mapping and inject the right scopes and claims into tokens, which is why we built Firely Auth to sit between the identity provider and the server, rather than asking a general-purpose product to speak FHIR.

We learned one lesson the hard way, too: audit belongs elsewhere. We once had a server that had become 98% audit events and hardly any actual data. Audit trails belong in Splunk, Elasticsearch, or your observability platform, not stored as resources next to the clinical data.

FHIR server architectures

Get the questions answered honestly, and the architecture decisions mostly make themselves.

Serving multiple separate client organizations off one deployment points toward multi-tenancy. A single organization with clean isolation needs is better served as single-tenant.

A legacy system you can’t migrate but still need to expose in real time calls for a facade in front of it. Otherwise, a native FHIR repository is the better fit.

And if multiple FHIR versions or US Core versions are in play, that usually means separate servers per version, with the proxy routing requests to the right one by profile, since resources don’t map one to one across versions.

None of these are exotic. All of it goes faster and cheaper when the right people answer the right questions before the first server gets provisioned. Plan the room first. The server is the easy part.

Whether you’re just starting to think this through, or already in the middle of it and want another perspective, get in touch. We’re always happy to talk it through.

The post How to plan a FHIR server deployment: stakeholders, questions, and architecture appeared first on Firely.

Scott and Wes tackle your questions on the rise of the design engineer, why AI still lacks “taste” (and why it’s about more than just looks), and how to actually write tests in the age of AI-assisted coding. Plus: is AI a bubble about to burst, keeping coding agents efficient in massive codebases, introducing kids to AI, a Linux life update, and more!
