🚀 Speed Up Windows Instance Launches with EC2 Fast Launch – Now Easier Than Ever!

#aws #ec2 #devops #vpc

🧠 What is EC2 Fast Launch?

EC2 Fast Launch improves launch time for Windows EC2 instances by pre-initializing AMI snapshots, resulting in:

⚡ Faster instance boot times ⏱️ Reduced wait for RDP and service readiness 🔁 Better support for auto-scaling, blue/green deployments, or patch testing

🛠️ How to Enable EC2 Fast Launch (via Console) 

Open the Amazon EC2 Console: 👉 https://console.aws.amazon.com/ec2/ In the left navigation pane, choose Images > AMIs. Select your Windows AMI by checking the box next to its name. Click on Actions > Configure fast launch. On the configuration page: ✅ Check "Enable fast launch for Windows" 📊 Choose your anticipated launch frequency — AWS uses this to maintain pre-provisioned snapshots matching your launch volume. Click Save changes.

❌ How to Disable EC2 Fast Launch 

Open the EC2 Console > AMIs section. Select the AMI you want to update. Click Actions > Configure fast launch. On the page: ❎ Uncheck the "Enable fast launch for Windows" box. 🔄 This will delete pre-provisioned snapshots and revert the AMI to standard launch behavior. Click Save changes.

📝 Note: If you want to enable it again later, you'll need to reconfigure everything after snapshots are removed.

📈 Why It Matters 

🚀 Launch Windows instances faster without the setup hassle 💡 Simplifies infrastructure for automation and CI/CD 🔧 Works even without a Default VPC 🛡️ Ideal for custom networking setups and scale-out scenarios
