Garuda: Automagically Exposing Djagno ORM over gRPC for microservices written in any other languages
1 like•391 views
This document introduces Garuda, a tool that automatically exposes the Django ORM over gRPC for microservices written in any language. It discusses microservice architectures and common implementation methods like CLI, HTTP, and RPC/Thrift. It then describes how Garuda makes RPC implementations easier by generating gRPC services from Django models. Finally, it provides an overview of gRPC and Protobuf and previews a demo of Garuda.

- 3. I have no idea what I am talking about
- 4. Microservices I am assuming that everyone has a basic understanding of a microservice architecture For the uninitiated, it is an architectural style that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservice architecture enables the continuous delivery/deployment of large, complex applications. It also enables an organization to evolve its technology stack.

- 6. CLI Call a command line/console application with Popen or something similar Very notorious (because we have limited control over the called program) Scaling is a bit tricky
- 7. HTTP Build a REST / SOAP endpoint Document the message exchange format (which is a manual process and might be error prone) relatively easier to scale compared to CLI method
- 8. RPC & Thir Build RPC Server and clients Just as easy to scale as HTTP method, but this is faster because of strongly typed messages serialize and deserialize very fast and data is smaller compared to JSON / XML Relatively harder (Implementation wise) because of all the learning curve involved We have well-de ned Data schemas; So manual intervention is not required to communicate changes
- 9. Garuda How to make the RPC Implementation relatively easier Introducing Garuda Automagically Exposing Django ORM over gRPC for microservices written in any other languages It's done with the help of gRPC (for now). So you need to understand Protobuf, gRPC and the likes.
- 10. RPC Frameworks gRPC: A high performance, open-source universal RPC framework Cap'n Proto: Cap'n Proto is an insanely fast data interchange format and capability-based RPC system.
- 11. Protobuf (Which we use with gRPC) Protocol Buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. message Article { string id = 1; string content = 2; int32 status = 3; string title = 4; }
- 12. gRPC Service De nition service Blog { rpc CreateArticle (Article) returns (Article) {} rpc UpdateArticle (Article) returns (Article) {} }
