Microservices Architecture
Microservices architecture structures an application as a collection of small, independently deployable services, each owning a single business capability and its data. Services communicate over APIs or messaging, allowing teams to build, scale, and release parts of the system separately.
Technical Architecture & Deep-Dive
Microservices replace a single monolithic codebase with focused services such as billing, users, and notifications. Each can use its own language, database, and release cadence, which helps large teams move independently.
The cost is distribution: a single screen may need data from five services, and exposing them all directly to clients causes chatty network traffic and leaks internal topology. An API gateway or Backend for Frontend aggregates those services into client-shaped responses, keeping the frontend fast and decoupled.
Key Architectural Benefits
Implement Microservices Architecture at the Edge
Deploy lightweight API aggregation, edge caching, and secret injection in minutes without Docker containers or complex servers.
Frequently Asked Questions
Q:Why do microservices need a BFF or gateway?
Without one, clients must call many services sequentially and understand internal URLs. A BFF aggregates calls in parallel at the edge and returns one tailored response.
Related Architecture Concepts
Backend for Frontend (BFF) is an architectural pattern where a dedicated gateway layer is created for a specific frontend client (e.g., iOS, Android, React). Instead of clients calling multiple generic backend APIs, the edge BFF aggregates upstream calls, injects credentials, and strips unneeded payload fields before transmission.
API Aggregation is the process of combining multiple distinct API calls into a single unified HTTP request. An intermediate edge gateway queries multiple upstream services in parallel, merges the returned data, and delivers a consolidated response to the client, drastically reducing mobile latency and network overhead.
A service mesh is an infrastructure layer that manages communication between internal microservices, typically using sidecar proxies deployed next to each service. It provides service discovery, mutual TLS, retries, and observability for east-west traffic without changing application code.
The Circuit Breaker pattern is a software resiliency design that monitors upstream service health and temporarily halts requests to failing endpoints. By failing fast and returning cached fallback data, it prevents cascading system outages and reduces recovery time.
Ready-to-Use Edge Recipes
To solve call two rest apis in parallel and return merged payload, never execute unauthenticated requests or embed private tokens directly in client bundles. RealComposer acts as a sub-10ms edge gateway running on Cloudflare Workers that securely injects credentials from your Secret Vault, normalizes responses, and prevents unauthorized API usage. Route calls through your RealComposer edge URL to guarantee complete privacy, robust origin validation, and low mobile latency.
