Microservices Architecture
Split the parts that need it, keep the rest simple
Microservices Architecture
As an application grows, some parts may need to scale, change or fail on their own, such as payment processing or report generation. Microservices move those parts into separate services, each with its own code, data and deployment. They also add moving parts: more servers to run, more deployments, and failures that cross from one service to another. We find where your application actually struggles, split out only the parts that benefit, and run them in Docker and Kubernetes with queues between them. For many small teams a well-organised single application is the better choice, and we will say so.
What We Deliver
What's included in Microservices Architecture.
Service boundaries
We decide which parts of the application should become separate services, and which data each one owns, before any code moves.
API gateway
One entry point that routes requests to the right service and handles login checks and rate limits in one place.
Queues and events
Background work and messages between services run through RabbitMQ or Redis queues, so a slow service does not hold up the user.
Handling failure
Timeouts, retries and fallbacks, so a service that goes down is less likely to take others down with it.
Logs and tracing
Central logs and request tracing with OpenTelemetry, so you can follow one request across services and see where it failed or slowed down.
Separate deployments
A Docker build and deployment pipeline for each service, so one service can be updated on Kubernetes without redeploying the rest.
Our Process
How the work runs, step by step.
Review the current system
We look at your code, traffic and team, and find which parts actually need to be separate, if any.
Plan the split
We agree the service boundaries, how services talk to each other, and the Docker and Kubernetes setup they will run on.
Extract one service at a time
Each service is moved out of the main application while the rest keeps running, starting with the one that gives the most benefit.
Monitor and harden
Logging, tracing, alerts and timeouts go in before the next service is extracted.
Handover
You get the documentation, deployment pipelines and source code, and we stay on for changes or ongoing support if you need it.
Frequently Asked Questions
Common questions about Microservices Architecture.
Probably not, if you are a small team with one application that runs well. A well-organised single application, sometimes called a modular monolith, is cheaper to host and easier to change. Microservices start to pay off when parts of the system need to scale or be released separately, or when several teams keep getting in each other's way in one codebase.
Usually, yes. We put a gateway in front of the existing application and move one feature at a time to a new service, switching its traffic over once it is tested. The old code stays in place as a fallback until the new service has run for a while.
Each service owns its own data, and changes are passed between services as messages on a queue. Another service may see a change a moment later rather than instantly, so we design workflows such as orders and payments to cope with that, including steps that undo earlier work if a later step fails.
Usually, yes. Several services on Kubernetes need more hosting and more monitoring than one application on a single server. We weigh that cost against what the split saves you before recommending it.
Other Backend & APIs services
- REST API Development REST APIs built in Laravel or Node.js for your website, mobile app or partner integrations, with documentation your developers can work from.
- GraphQL API GraphQL APIs in Node.js or Laravel that let web and mobile apps fetch the fields they need in one request, built new or added to an existing backend.
- Database Optimization Speeding up slow MySQL, PostgreSQL and MongoDB databases with better queries, indexes and caching, measured before and after.
