Munander Maan presented an introduction to gRPC, a modern, fast and efficient open-source framework developed by Google. The presentation covered what gRPC is, how it works internally using Protocol Buffers, its advantages over REST APIs, how it achieves scalability, and different types of APIs that can be built with gRPC. The agenda included deep dives into gRPC internals, comparisons with REST, scalability, and API types.

- 2. Lack of etiquette and manners is a huge turn off. KnolX Etiquettes Punctuality Respect Knolx session timings, you are requested not to join sessions after a 5 minutes threshold post the session start time. Feedback Make sure to submit a constructive feedback for all sessions as it is very helpful for the presenter. Silent Mode Keep your mobile devices in silent mode, feel free to move out of session in case you need to attend an urgent call. Avoid Disturbance Avoid unwanted chit chat during the session.

- 4. c What is gRPC? gRPC is a Free and open-source framework developed by Google. 1. Modern,fast and efficient 2. Supports Streaming 3. Language Independent 4. Uses Protocol Buffers and HTTP/2
- 5. OUR MISSIONInsert Your Subtitle Here 1. At the core of gRPC, you need to define the messages and services using Protocol Buffers. 2. The rest of the gRPC code will be generated for you and you will have to provide an implementation for it. Getting started with gRPC

- 7. 1 2 3 Easy to write message definition Definition of API is independent from Implementation Code can be generated in any language Why Protocol Buffers?
- 8. • gRPC uses Protocol Buffers for communications. • Lets measure the payload size vs JSON. Efficiency of Protocol Buffers over Json
- 9. STRATEGY INFOGRAPHICInsert Your Subtitle Here The client & server can push messages in parallel over the same TCP connection. This greatly reduces latency. Binary Servers can push streams (multiple messages) for one request from the client. 1. Headers can be compressed. 2. These have much less impact on the packet size. Protocol buffers is a binary protocol and makes it s great match for HTTP/2. Header Compression Multiplexing Server Push Why HTTP/2

Insert Your Subtitle Here01 This means they do not block threads on request02 Therefore each server can serve millions of requests in parallel03 gRPC clients can be asynchronous or synchronous.04 Google has 10 BILLION gRPC requests being made per second internally. Proof of scalability 10 BILLION Scalability In gRPC 01 gRPC Servers are asynchronous by default. 05 05 gRPC clients can perform client side load balancing
