Fleet vs KubeAdvisor: What are the differences?
Developers describe Fleet as "Container management and deployment for your cluster". Fleet is a low-level cluster engine that feels like a distributed init system. With fleet, you can treat your CoreOS cluster as if it shared a single init system. On the other hand, KubeAdvisor is detailed as "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.
Fleet and KubeAdvisor belong to "Container Tools" category of the tech stack.
Some of the features offered by Fleet are:
- Deploy docker containers on arbitrary hosts in a cluster
- Distribute services across a cluster using machine-level anti-affinity
- Maintain N instances of a service, re-scheduling on machine failure
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
