Chapter 14: EC2 Operations — Elastic IP, AMI, Snapshots and Vertical Scaling

Mitranno, launching a server is only day one. In real projects, the day-two work matters more: keeping the same IP when you replace a server, taking a backup before an upgrade, cloning a perfectly configured server in minutes, and giving a slow server more CPU and RAM. Ekdum practical chapter aahe — let's learn these operations one by one, and please do every lab with me.
