In this quick lecture, we focus on how to quickly instantiate applications on EC2 instances, RDS databases, and EBS volumes. In previous discussions, we explored solution architecture but didn't address how to install and deploy applications efficiently on AWS.
Deploying a full-stack application can take a lot of time due to:
❌ Installing applications and dependencies
❌ Configuring system settings
❌ Recovering data
❌ Initializing databases
To speed up the process, we can leverage AWS features designed for faster startup and deployment.
A Golden AMI is a pre-configured Amazon Machine Image that includes:
✅ Installed applications
✅ OS dependencies
✅ Pre-configured settings
Instead of installing everything every time a new instance is launched, we create an AMI from a fully set up instance. This allows new instances to launch almost instantly with everything ready to go.
🔹 Benefits of Golden AMI:
✔️ Fast instance boot time (no need to reinstall applications)
✔️ Consistent configuration across instances
✔️ Efficient scaling—new EC2 instances are ready in seconds
