What is Difference Between Kubernetes and Rancher
The difference between Kubernetes and Rancher is that Kubernetes is a technology for managing containers organized under a cluster of virtual or physical machines. Rancher is a technology for managing Kubernetes clusters en masse. Both of these tools are important considerations for any organization building a cloud-native, DevOps technology stack.
Kubernetes is the leader in container orchestration. It offers teams the flexibility to efficiently run containerized workloads across multiple public cloud providers and hybrid cloud environments. Kubernetes offers advanced scheduling and scaling capabilities to ensure application performance and high availability. However, its functionality focuses on managing resources within a single cluster.
Rancher, on the other hand, is a platform designed to manage multiple Kubernetes clusters. It eases Kubernetes cluster management in large environments in several ways. For example, Rancher simplifies operations such as cluster provisioning, centralized security management, and monitoring workloads using popular tools such as Prometheus. Additionally, Rancher has an extensive application catalog of Helm charts for various applications such as Kubecost, Prometheus, Grafana, and MySQL.
Kubernetes Features
The following table summarizes some of the key benefits of using Kubernetes:
1)Cloud provider-agnostic
Kubernetes based platform is easily migratable across cloud providers
2)Enables easy scaling
Containerized applications are comparatively easier to scale as compared to traditional applications hosted in virtual machines (VM)
3)Resource usage optimization
Configuration parameters make it relatively easy to control cluster density and autoscaling
4)Self-healing
In case of a node failure, pods are automatically rescheduled to other nodes

Rancher Features
1)Cluster provisioning and import
Rancher lets you create new clusters or add existing ones to it
2)The concept of projects
Rancher introduces the concept of projects for better grouping of namespaces
3)Extended RBAC control
User permissions can be configured per project across clusters
4)Easy workload deployment
Users can use the Rancher UI to deploy their workloads without updating a YAML file
5)Monitoring and alerting
Allows users to create notifications and push cluster logs to different backends
5)Extensive application catalog
Similar to the app store on your smart
Conclusion
The rapid adoption of Kubernetes leaves many teams with the cumbersome reality of managing too many clusters. Rancher is solving this pain point by simplifying and automating Kubernetes cluster management. With the addition of Kubecost, teams can allocate costs across clusters by aligning with the core concept of a Rancher Project, and using labels to further refine their cost visibility.
