Some organizations particularly those adopting a microservice approach to application design, can have hundreds, or even thousands of containers deployed from development through to production. While microservices do not specifically require any particular deployment model (see above), the granular independent nature of microservices make this approach very suitable for containerization.
#WHAT IS KUBERNETES CODE#
It minimises code dependencies, provides more flexibility in technology and supports increased reusability. This allows individual services to be scaled, upgraded or changed without impacting other microservices. Microservices describes an application design and development approach, that breaks an application into independent, loosely-coupled services that have clearly defined communication interfaces. Kubernetes provides the tools to tame and manage containers.

The ease of use and benefits of lightweight containers means that they tend to proliferate in number.
#WHAT IS KUBERNETES PC#
Developers can write code in a container on their PC or Mac, and the same container can then be deployed to any server-class operating system or to the cloud with no changes. 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.
#WHAT IS KUBERNETES SOFTWARE#
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.
