Bye bye WCF, hello gRPC

  1. 1. Bye Bye WCF, hello gRPC @svswaminathan .NET Conf Local Bengaluru – Oct 19, 2019 1
  2. 2. Swaminathan Vetri SWAMINATHANVETRI.IN 2 Technical Architect, Maersk | Microsoft MVP Speaking, Blogging, Photography, Travelling Gadget freak Twitter : @svswaminathan Blog : swaminathanvetri.in
  3. 3. Agenda • State of WCF in .NET Core 3.0 ? • What is gRPC ? • Why gRPC ? • What it offers ? • gRPC – C Core vs gRPC-dotnet • Demos
  4. 4. State of WCF in .NET Core 3.0 • What didn’t make it to .NET Core 3.0 ? • WCF Server, Workflow, ASP.NET WebForms, Remoting, App Domains • Core WCF – open source community project • WCF Client components are part of .NET Core 3.0 SWAMINATHANVETRI.IN 4
  5. 5. What is gRPC ? • gRPC is a modern open source high performance RPC framework that can run in any environment SWAMINATHANVETRI.IN 5
  6. 6. Protocol Buffers • Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler Sample proto format message Person { string name = 1; int32 id = 2; bool has_ponycopter = 3; } SWAMINATHANVETRI.IN 6
  7. 7. Why Protocol Buffers ? SWAMINATHANVETRI.IN 7 Simpler 3 to 10 times smaller 20 to 100 times faster Less ambiguous Generate data access classes that are easier to use programmatically
  8. 8. How gRPC works ? SWAMINATHANVETRI.IN 8
  9. 9. Why gRPC? SWAMINATHANVETRI.IN 9 PERFORMANCE INTEROPERABILITY USABILITY & PRODUCTIVITY STREAMING SECURITY
  10. 10. What it offers ? SWAMINATHANVETRI.IN 10
  11. 11. WCF vs gRPC WCF • Service Contract, Operation Contract, and Data Contract • Contracts written in C# or Visual Basic • Configurable, including SOAP/XML, Plain XML, JSON, .NET Binary, and so on. • Interop when using SOAP over HTTP • Networking configured at runtime. Switch between TCP, HTTP, MSMQ, and so on. • Runtime generation of serialization /deserialization and networking code in base classes • Authentication, WS-Security, message encryption gRPC • Uses proto file to declare services and messages • Protocol Buffer language • Protocol Buffer binary format (although it’s possible to use other formats). • Official support: .NET, Java, Python, JavaScript, C/C++, Go, Rust, Ruby, Swift, Dart, PHP. Unofficial support for other languages from the community. • Always HTTP/2 • Build-time generation of serialization /deserialization and networking code in base classes • Credentials, ASP.NET Core security, TLS networking SWAMINATHANVETRI.IN 11 Source : http://aka.ms/grpcforwcfebook
