Basics​

Approaches: There are two ways in which you can create and manage your infrastructure

  • Manual approach
  • Through automation

Examples​

Example 1: Database backup

  • Requirement: I was assigned a task to take a database backup every day at 10 PM, and the backup had to be stored in Amazon S3 Storage with an appropriate timestamp
    • db-backup-01-01-2024.sql
    • db-backup-01-02-2024.sql
  • Bad solution: Initially, due to a lack of time, I used to take a DB backup manually at 10 PM and upload it to S3
  • Lesson
    • If a particular task has to be done in a repeatable manner, then it MUST be automated
    • Depending on the type of task, the tools for automation will change

Example 2: A single service

  • A set of resources (Virtual Machine, Database, S3, AWS Users) must be created with the exact same configuration in Dev, Stage, and Production environments
