This text provides insight into the history of container technology, which has transformed container management, appealing to developers and infrastructure managers looking to explore this field.
Initially, the only option was a physical server to set up computational environments. As technology advanced, virtual machines (VMs) were developed to enable multiple operating systems to run on a single physical server, reducing hardware costs. However, this approach still required resource-intensive management and lengthy configuration processes for each feature.
Containers were developed to isolate applications and dependencies, creating a new approach to building applications.
The popularity of using containers to enhance task processing efficiency and flexibility has grown significantly due to the increasing prominence of cloud computing and microservice designs, creating a critical need for effective management of extensive container clusters.
Kubernetes is an influential open-source platform that can effectively manage workloads, services, and containers. It has the capability to orchestrate and oversee all container resources, including network, load balancing, security, and sizing on Kubernetes nodes.
Kubernetes includes internal isolation features like namespaces that enable grouping container resources based on access permissions and environment preparation. These functionalities facilitate IT in offering self-service options to developers and promoting collaboration in intricate microservice architectures without necessitating the representation of the entire application in the development environment. Kubernetes simplifies software complexity management.
As business software grows more intricate, DevOps teams require a tool to manage this complexity by starting all necessary services for applications to function properly and communicate effectively.
The Rancher arrived to manage Kubernetes by providing a unified interface and a collection of tools for deploying, running, and overseeing Kubernetes clusters across various environments.
The answer: Within Kubernetes
Kubernetes manages a Kubernetes cluster on external infrastructure such as AWS EKS, Azure AKS, or Google GKE, with support and administration provided by the respective cloud service.
Under Kubernetes eliminates the need to be concerned about installation, licensing, and maintenance. It can be utilized on any operating system, and users have the option to select either the open-source or Enterprise version of Rancher, both supported by Under.
