Add-ons are third-party (and native AWS) solutions that provide the functionality needed to optimize the efficient running of EKS Blueprints. Add-ons allow you to configure the tools and services you want to run to support your EKS workload. When you configure add-ons for a blueprint, the add-ons are made available at deployment time. Add-ons can deploy both Kubernetes-specific and AWS resources needed to support the add-on functionality.
The benefit of leveraging the EKS Blueprints Add-on is that you extend your ability to leverage open-source projects and tools built by the Kubernetes community. These projects and tools address different areas of running your workload on Kubernetes such as security, observability, CI/CD, GitOps, and more.
