It provides the list of vulnerabilities that threaten each container and can sends notifications whenever new vulnerabilities that affect existing containers are released; KubeAdvisor: It helps DevOps adopt best practices for Kubernetes. It helps teams adopt best practices to accelerate the adoption of Kubernetes, and optimize their existing stack, with machine learning. It scans K8s to make infrastructure and cloud-native applications reliable, resilient, and observable.
Clair and KubeAdvisor belong to "Container Tools" category of the tech stack.
Some of the features offered by Clair are:
- api defines how users interact with Clair and exposes a documented HTTP API.
- worker extracts useful informations from layers and store everything in the database.

On the other hand, KubeAdvisor provides the following key features:
- Performance by continuously watching throttled containers/apps and recommending improvements
- Utilization by comparing used resources with the available capacity to reallocate them based on variable workloads
- Cost Optimization by suggesting changes at the VM level to save money in case of cloud infrastructure or identify the best configurations if you are running Kubernetes on-prem
