Microservices can separate workloads and release responsibilities, but they also distribute the failure paths your team must understand. EidenTech can review whether this approach fits an application and scope a measured implementation or extraction. We start with the reason for separating a service, the records it owns, and the people who will operate it. Splitting code alone does not establish a useful service boundary.
How we approach your project
Establish a reason for each service boundary
Look for concrete requirements such as an independently changing business capability, a workload with different capacity needs, or clear ownership by a separate team. We compare these with a modular application that can still keep related logic together. A boundary should avoid forcing ordinary business actions through unnecessary network calls. The review includes release coordination, operational experience, and dependency direction. If the current problem is an expensive query or unclear module structure, separate deployment may not address it and can make troubleshooting more difficult.
Define contracts and authoritative data
Each proposed service needs a clear contract, ownership of relevant records, and rules for sharing information. Several services writing the same tables can preserve tight coupling while making deployment more complicated. We identify which operations use synchronous requests and which can accept asynchronous events. Contract changes must account for consumers that update at different times. Read models or cached information also need freshness expectations. The interface and consuming services should know when a value is authoritative, a snapshot, or temporarily unavailable rather than treating every response as current.
Design for partial completion and repeated work
A business operation spanning services may succeed in one place and fail in another. We review states representing partial completion, the retry owner, and compensating or reconciliation actions. Repeated events, delayed responses, and out-of-order delivery need deliberate behaviour. A stable operation identifier can distinguish a retry from a new request where supported. Identify actions requiring human review because reversing one step cannot safely undo the entire operation.
Plan deployment and diagnosis before increasing the count
Independent services introduce configuration, credentials, release compatibility, and monitoring across several runtime units. The team needs a way to follow an operation through them without collecting unnecessary personal information. We scope health checks, useful logs, dependency status, and alert ownership for the chosen platform. Deployment controls should consider old and new contract versions during rollout. Container orchestration is one possible option rather than a default requirement. The operating plan should match the actual number of services and the people available to maintain them.
Extract one capability and verify the transition
For an existing application, a focused extraction can test the approach without moving every module at once. Identify the capability, how requests are routed during transition, and when data ownership changes. Avoid leaving two systems independently accepting authoritative writes without a defined synchronisation strategy. Verification covers contract compatibility, permission checks, business outcomes, and dependency failure. We document the evidence and unresolved costs before recommending further separation. A successful first extraction can inform the next decision; it is not a promise that all parts of the product should become services.
What we can deliver
We agree the requirements and responsibilities before development begins. Your project scope can include:
- A boundary assessment comparing separate services with a modular application approach.
- Service contracts, data-ownership rules, and synchronous or asynchronous interaction plans.
- Scoped service implementation or extraction with defined partial-failure behaviour.
- Deployment, monitoring, and recovery guidance suitable for the intended operating team.
- Contract and transition checks with a documented decision on subsequent migration work.
Technology choices for your requirements
The stack follows your integrations, operating model, and maintenance needs. These are options to review during discovery, rather than a fixed stack promised for every project.
- Node.js and TypeScript services or another runtime required by the existing platform
- REST APIs, provider-supported messaging, and service-owned persistence where appropriate
- Containers, CI/CD, and tracing or logging tools selected for the deployment model
Planning questions, answered
Can you split an existing application gradually?
Yes. We can review a specific capability and scope an extraction with controlled routing and data ownership. The transition plan includes compatibility and recovery, allowing the team to evaluate the approach before committing to further service separation.
Will microservices make the application faster?
They do not guarantee faster responses. Additional network calls and coordination can add overhead. We first identify the performance or scaling requirement, then compare targeted application improvements with independent services using evidence relevant to the workload.
Should each service have its own database?
The important decision is authoritative data ownership and permitted access. Separate persistence can support independence, but introduces consistency and reporting questions. We review the business transactions and migration constraints instead of applying a database-per-service rule without context.
Do we need Kubernetes for microservices?
Not necessarily. The deployment approach follows service count, workload, availability requirements, and operating capacity. Managed hosting or simpler container deployments may fit; any orchestration platform adds account, configuration, monitoring, and maintenance responsibilities that need explicit scope.
