Cloud & Microservices

Middleware Architecture for Scalable Systems Middleware sits between applications and the core services they rely on. It coordinates requests, handles transformation, and applies common rules. A well-designed middleware layer helps systems scale by decoupling components, buffering bursts, and making behavior visible. Start with a clear goal: reduce latency where it matters, tolerate failures, and simplify deployments. Decide which responsibilities belong in middleware, and which belong to service logic. The right balance gives you flexibility without creating needless complexity. ...

Microservices design for resilience and scale Microservices promise faster delivery and team autonomy, but they add complexity. When services fail or traffic spikes, a well-designed system stays responsive and safe. Resilience is a design discipline: plan for failure, automate recovery, and observe behavior in real time. The aim is to isolate faults, limit blast radius, and keep users satisfied even when parts of the system struggle. Start with clear service boundaries, and think about how components recover without human help. ...

Microservices Architecture Design and Tradeoffs Microservices break a software system into small, independent services. Each service owns a specific capability and can be built, tested, and deployed separately. This approach can speed up delivery and help teams work in parallel. It also adds complexity: more moving parts, distributed decisions, and new failure modes. The challenge is to gain speed without losing reliability. Start with clear domain boundaries. Use domain-driven design to group related ideas and avoid many tiny services. A practical rule is to align services with business capabilities and with who owns the data. If two parts of the business share data, decide who writes and who reads, and how to keep data in sync. ...
