This is very useful for development and deployment workflows. This means that the same container can be run unaltered on multiple target systems like Windows, Linux, Unix, macOS and various public cloud providers. They are also decoupled from the hardware as well as the underlying operating system. Multiple containers running on the same hardware are still independent like VMs are. Containers do have their own file system, CPU allocation, memory, and process space. As such they are considered more lightweight than VMs. Containers are similar to VMs, but they don’t have their own copy of an operating system to carry. Each virtual machine still has a separate copy of an operating system and other dependencies within the virtual machine independently from any other VMs.Ĭontainerization takes the level of abstraction a step further. Most people are familiar with the virtualization model where a hypervisor allows virtual machines (VMs) to be abstracted from the underlying hardware. The following diagram shows the path from traditional deployment to virtualized deployment, and on to containerization. Containers grew out of the virtualization deployment era of infrastructure management, which in turn was built upon what is commonly known as the traditional server deployment model.
The role that Kubernetes performs and the need for it requires an understanding of containers in software deployment. It is pronounced “koo-ber-net-ees” and is often abbreviated to ‘k8s’ or ‘k-eights’ in conversations and text. Kubernetes provides guiding services to help navigate an ever-increasing proliferation of containers. The name Kubernetes is derived from the Greek word for helmsman or pilot. It is now one of the fastest growing open source projects in history. Kubernetes grew out of an internal project to streamline containerized application management within Google and has seen rapid and widespread adoption. Kubernetes is an open-source platform for managing containerized applications at scale. With the recent addition of the Kemp Ingress Controller for Kubernetes (available now in LoadMaster firmware 7.2.53), what better time to look at the role Kubernetes plays in delivering Microservice Applications.
