Quick Notes and Practice Samples

1. Intro to gRPC
2. Getting Started gRPC
   • Client Stub
   • Sever Stub
   • Protoc Compiler
3. gRPC Communication Patterns
   • Simple RPC (Unary RPC)
   • Stream RPC
     • Server Streaming
     • Client Streaming
   • Bidirectional Stream
4. gRPC - Under the hood
   • Bi-Directional flow of information
   • Using HTTP/2 for communication
   • Length-Prefixed Message Framing (why gRPC is fast)
5. gRPC: Beyond the Basics
   • Interceptors
   • Server Side - Unary Interceptor
   • Server Side - Stream Interceptor
   • Client Side - Unary Interceptor
   • Client Side - Stream Interceptor
   • Deadlines
   • Cancellation
   • Error Handling
   • Multiplexing (multiple service on same gRPC server)
   • Metadata (sending and receiving)
   • Load Balancing
   • Compression of gRPC message
6. Secured gRPC
   • Generating Certificates for Client | Server | CertificateAuthority
   • One-Way Secured Connection (TLS)
   • Two-Way Secured Connection (Mutual TLS - mTLS)
7. gRPC in Production
   • Testing a gRPC Server
   • Testing a gRPC Client
   • Load Testing
   • Continuous Integration
   • Deployment (Docker)
   • Deployment Kubernetes - Deployment + Services + )
   • Metrics (Prometheus | OpenCensus)
   • Logs
   • Tracing (zipkin)
