REST API design focuses on creating clean, efficient, and scalable web services.

An API Gateway simplifies client access to backend services in microservices.

API pagination helps manage large datasets by breaking them into smaller parts.

API Gateway, Proxy, and Load Balancer serve different roles in managing requests and traffic in systems.

REST, RPC, and gRPC are different methods for communication in software systems.

HTTP methods tell the server what to do, and status codes tell us the result.

gRPC allows efficient communication between services using a structured request-response model.

Idempotency ensures that repeated operations in APIs do not cause duplicate effects.

Connection pooling reuses database connections but can cause issues if misconfigured.

gRPC supports four communication patterns: Unary, Server Streaming, Client Streaming, and Bidirectional Streaming.

Choosing the right boundaries for microservices is crucial for effective architecture.

Search engines collect, index, retrieve, and rank documents to provide relevant results.

A reverse proxy routes client requests to different backend services efficiently.

Microservices can communicate using five key patterns based on their needs.

Protobuf schema evolution requires careful changes to avoid breaking existing clients.

Token Bucket allows burst traffic, while Leaky Bucket smooths out traffic flow.

Database per Service ensures each microservice owns its data, reducing dependencies.

The Token Bucket algorithm helps manage how many requests a server can handle.

Transactions ensure database operations are reliable using ACID properties.

Tokenization and analyzers help search engines process and match text effectively.

Monolithic and microservices architectures each have unique advantages and challenges for software development.

Elasticsearch aggregations help summarize data using metrics for calculations and buckets for grouping.
