Scalable Performant Microservices


Description

This is PART-2 of Spring WebFlux course series.

Spring WebFlux is a reactive non-blocking web stack which is scalable & provides better performance compared to traditional Spring Web MVC! In a Microservices architecture we do have a lot of network calls - to database servers or external APIs. sometimes we might do a heavy computation. How to avoid unnecessary network calls & heavy re-computation and How to make our Microservices more scalable. That is what this entire course is about!

By the end of this course you would be comfortable with:

  • Microservices Caching With Redis

    • Redis

      • Various Redis Data Structures

      • Key/Value

      • List

      • Set

      • Sorted Set

      • Hash

      • HyperLogLog

      • Redis PubSub

      • INCR / DECR

      • Queue / Stack

      • Rate Limiting

      • Batch

      • Transaction

      • Access Control List


  • Spring Data Reactive Redis / Redisson

      • A Java library for Redis which supports reactive streams

    • Cache aside pattern with annotations

    • Cache aside pattern for Reactive types

    • Creating a generic cache template

    • Caching, evicting cache

    • Local Cached Map

    • Capturing expired and deleted events from Redis

    • JMeter Performance Test which proves 80% performance improvement


  • Redis As Message Queue

    • Redis can be used as a message queue in Microservices architecture

    • We would demonstrate that in this course.

    • You even implement a Priority Queue using Redis


  • WebFlux WebSocket  + Redis PubSub

    • Developing a chat application using Spring WebFlux Websocket

    • Messages broadcasting using Redis Pub/Sub

    • Creating a chat room


  • Finding Trend

    • Developing a Product service which offers thousands of products

    • Finding a product trend based on users view

    • Pushing real time updates


  • Geospatial

    • Redis Geo spatial Data structure

    • Creating a restaurant locator application using Spring WebFlux + Redis

    • Based on the zip code provided, locate the nearby restaurants

Before taking this course I was thinking that Redis is just for caching, and I wanted to learn how to use it in reactive manner. BUT! I was mistaken. I am glad to take Vinoth's course! It is WONDERFUL! A lot of time we spent with studying Redisson - high-performance async and lock-free Java Redis client. Using it in Spring application can improve performance (comparing to Spring Data Redis). Vinoth shows how to use Redis build-in features to improve application functionality (in a couple of lines of code we made PriorityQueue, using GeoSpatial is Awesome - we made practical application with Google Maps API). Chat application based on WebSockets, Redis and JavaScript is COOL to start working with WebSockets! Thanks a lot for this course! I am waiting for the next Reactive Course Series, especially Redis Stream and WebFlux Security!
