File: AmazonECS/latest/developerguide/capacity-launch-type-comparison.md

Summary

Updated terminology to consistently use 'Amazon EC2 Auto Scaling group' instead of 'Auto Scaling group' or 'EC2 Auto Scaling group' in multiple sections for clarity and product name accuracy

Security assessment

The changes are purely documentation improvements for terminology consistency and product name accuracy. There is no mention of security vulnerabilities, mitigations, or new security features. The updates focus on clarifying capacity provider types without addressing security controls or risks.

-Amazon ECS provides two methods for configuring capacity for workloads. You can use launch types or capacity providers. Launch types include EC2, Fargate, and External. Capacity providers offer enhanced flexibility and advanced features for capacity management. You can run workloads on serverless compute with Fargate and Fargate Spot capacity providers, on self-managed EC2 instances through Auto Scaling group capacity providers, or on fully-managed compute using Amazon ECS Managed Instances capacity providers that combine the simplicity of Fargate with the flexibility of EC2 compute. Capacity providers offer better control over resource allocation and can help optimize both performance and costs. Capacity providers are the recommended way to configure capacity for workloads compared to traditional launch types. Use the following to understand the differences between capacity providers and launch types.

-When you launch tasks or services, configure a capacity provider strategy. Amazon ECS supports following capacity providers: Fargate and FARGATE_SPOT, Auto Scaling groups for self-managed EC2 instances, and Amazon ECS Managed Instances. Note that Spot Fleet is only available as a capacity provider and not as a launch type. You can create one or more Amazon ECS Managed Instances or Auto Scaling groups capacity providers in a cluster. Fargate and Fargate Spot capacity providers are created and managed by Amazon ECS on every cluster and you do not need to create them. A cluster can have a mix of all capacity provider types, however, a capacity provider strategy can't have a mix of different capacity provider types.
