What is the difference between AWS ASG Launch Templates and Launch Configurations

Question

I'm trying to understand the difference between Launch Templates and Launch Configurations in AWS. Can anyone break it down for me?

Answer 1

In AWS Auto Scaling, we have two main tools to define how EC2 instances get launched: Launch Templates and Launch Configurations. Both work as blueprints for setting up instances, but they differ in flexibility. Just glance at the table below to learn the actual difference.

Feature	Launch Templates	Launch Configurations
Flexibility	Gives you more options and supports of new features	It has basic setup and  fewer options
Versioning	You can create versions, making updates easy	No versioning, so you’d need to create a new config for changes
Cost Optimization	Lets you mix instance types and use spot instances for savings	Only one instance type, no spot instance support
Advanced Features	Supports the latest AWS features you may need	Doesn’t support most new features
Recommended For	Perfect if you want a flexible, modern setup	Better for older setups that don’t need new features

If you're looking for more flexibility and control, go with Launch Templates! They let you use the latest AWS features, mix instance types, and save on costs with spot instances. Built for both simple and advanced setups, Launch Templates keep you ready for the future.
