Architecture Patterns
13 topics in architecture patterns.
CQRS
CQRS separates read and write models so each can be optimized independently — write to a normalized database, read from a denormalized projection.
Client-Server Architecture
Client-server is the most fundamental architectural pattern. Understanding it is the starting point for all system design discussions.
Event Sourcing
Event Sourcing stores every state change as an immutable event. The current state is derived by replaying events, providing a complete audit trail and.
BFF Pattern
Backend for Frontend (BFF) creates dedicated backend services for each frontend type (web, mobile, TV), tailoring API responses to each client's specific.
Microservices Architecture
Microservices enable large engineering teams to work independently, deploy frequently, scale individual components, and use the best technology for each.
Serverless Architecture
Serverless eliminates operational overhead for many use cases. There are no servers to patch, no capacity to plan, and no idle resources to pay for.
Strangler Fig Pattern
The Strangler Fig Pattern incrementally migrates a legacy monolith to microservices by routing traffic to new services one feature at a time, avoiding.
Blue-Green Deployment
Blue-green deployment maintains two identical production environments. Traffic switches from blue (current) to green (new) instantly, enabling.
Event-Driven Architecture
EDA enables loose coupling, scalability, and real-time processing. It is the architecture behind real-time analytics, IoT systems, and modern.
Canary Release
Canary release gradually rolls out a new version to a small percentage of users first, monitoring for issues before expanding to 100%, reducing the blast.
Peer-to-Peer Architecture
P2P eliminates the need for central servers, making systems more resilient and cost-effective for certain use cases.
Feature Flags
Feature flags toggle functionality on or off at runtime without code deployment. They enable trunk-based development, A/B testing, gradual rollouts, and.
Monolith vs Microservices
When to use a monolithic architecture versus microservices, the real tradeoffs involved, and practical migration strategies used by companies like.
