Description

Welcome to the course “Application Performance Optimization”. This course is designed to help you get started to understand the primers of performance affecting your application and how you can tune these primers.There could be a lot of factors that might affect the performance of your application. For example, the TCP connection parameters, webserver related optimization, tools that will help for performance debugging and tuning. We will be covering these topics in this course.The application code itself can affect the performance of the application single handedly but the application code optimization is beyond the scope of this course.We will be continuously improving the course by adding more topics around performance optimization.However, we are open to your feedback. If you think some more topics around optimization should be included in the course then feel free to suggest us and we will try to create more videos on it and will append to this course.What you will learn:What is performance/speed, its components and why is it important to address itWhat are the primers of OptimizationWhat is TCP/IP and how it worksWhat all factors affects TCP connections and how you can optimize itUnderstanding Bandwidth Delay Product and optimizing using BDP with a Demo and actual calculationWhat is HTTP1.X and its limitation. How HTTP2 overcomes the limitations of HTTP1.X and added improvement?TCP Optimization DemoVarious Optimization for a Webserver (Nginx) including fastcgi cache, http2, compression etc.Various Tools to help you optimize for example: ethtool, tunedHow to start optimizing and when to stopEvergreen performance best practicesIntended Learners:DevOps EngineersSystem AdministratorIT EngineersDevOps AspirantsCloudOps EngineersCloud EngineersPlatform EngineersSRE (Site Reliability Engineers)Prerequisites:Basic Understanding of LinuxKnowledge about Nginx & how it worksBasic Understanding of TCP/IPHow a web application works
