- 10. KUBERNETES CERTIFICATION TRAININGwww.edureka.co/kubernetes-certification A Container Management Tool !!! Kubernetes is an open-source Container Management tool which automates container deployment, container (de)scaling & container load balancing. Benefit: Works brilliantly with all cloud vendors: Public, Hybrid & On-Premises. • Written on Golang, it has a huge community because it was first developed by Google & later donated to CNCF • Can group ‘n’ no of containers into one logical unit for managing & deploying them easily More About Kubernetes Reference: https://kubernetes.io/
