Today, the majority of businesses are going through a digital transformation. While the digital journey brings speed, efficiency and mobility solutions to the table, it comes with certain challenges too. As you migrate the existing infrastructure to the cloud, you’ll have to deal with legacy issues. In the cloud, you have to manage a wide range of tools and services. The implementation of DevOps to manage your infrastructure gives you additional responsibilities.
The DevOps environment demands frequent and faster deployments every day. According to the State of the DevOps 2019 report, elite performers make 209 times more deployments than low performers.
They gain 106 times faster lead time from commit to deploy with a 7% change fail rate. The time to recover from incidents is 2,604 times faster than low performers.
Gone are the days when IT development was confined to software companies. Today, every enterprise develops and manages a wide range of software applications.
As such, tracking and managing automated deployments is a challenge. Kubernetes is here to help.
An Overview of Kubernetes
Kubernetes is a popular tool that enables administrators to orchestrate and manage server cluster workloads in a datacenter, including automation and declarative configuration. Also known as K8s, the Kubernetes open-source platform helps you in efficiently managing containerized apps and services. You can simultaneously run and manage multiple servers while providing access to resources 24/7. This is achieved with the implementation of distributed data processing that allows Kubernetes to run multiple servers of different kinds installed at different locations and operating on different platforms.
The Traditional Software Development Environment
In a traditional operations environment, multiple applications are hosted on a single physical server. It resulted in an inefficient allocation of resources as some applications consumed more resources while others were left out to underperform. Installing each application on a separate server consumed huge infrastructure expenses. Moreover, each server was underutilized. Virtual machines came as a solution to this issue. A virtual machine runs the operating system on top of the virtual hardware and contains all the required elements to run the applications. Using virtualization, administrators were able to isolate applications between different VMs and run multiple applications on the same physical machine.
The Advent of Containerization
The container technology takes this system to a next level. A container is a software package that is bundled with all the required components of the app such as binaries, dependencies, libraries and configuration files while isolating it from the underlying hardware. Containers are lightweight and enable administrators to seamlessly deploy workloads across multiple environments. Keeping the base image consistent, developers can run the app in any environment. By sharing the host OS, containers eliminate the need for libraries and boot OS and therefore become lightweight. They are highly scalable, highly portable, offer agility and provide application-centric management.
Today, enterprises simultaneously run hundreds of containers in different environments. As such, managing the deployment of containers, tracking each container and setting up a new container when a container is down is a challenge. Kubernetes helps you to define your deployment patterns and efficiently manage resilience in a distributed systems environment.
Kubernetes and Containerization
Kubernetes is the most popular container-deployment system for the following reasons. Firstly, it enables you to provide access to containers via an IP address or a DNS name. In addition to service discovery, it helps you to perform load balancing for routing traffic to the right container. Secondly, infrastructure management becomes easy as you can define the desired state of a container. At any given point in time, you can easily roll back the system to its desired state and create and terminate containers at your will. It supports self-healing wherein containers are automatically replaced or restarted. Be it local storage or a public cloud datacenter, Kubernetes allows you to mount storage automatically for efficient orchestration of storage.
While managing a cluster of servers, you can define resource allocation (RAM, CPU) for each container and Kubernetes will optimize the infrastructure by rightly fitting containers onto the nodes. It also allows you to securely store and manage secret information such as passwords, keys etc. without exposing them in the configuration of the stack.
What is it for Businesses?
Powered by Cloud Native Cloud Foundation (CNCF), Kubernetes is the fastest-growing open-source software which means you are entitled to use a wide range of open-source tools developed for Kubernetes. Portability is a big benefit of Kubernetes. It means you not only manage the automatic deployment of large clusters of servers but also moves them between multi-cloud environments with ease.
Kubernetes offers high scalability enabling you to run containers or different environments such as a virtual machine, public, cloud, bare metal. Organizations enjoy high availability at the infrastructure level as well as the application level. You can configure it to support multi-node replication or add a storage layer for the high availability of stateful workloads. Kubernetes uses a simple client-server architecture but offers amazing benefits such as auto-scaling, rolling updates, self-healing etc. Backed by Google, you can rest assured of its reliability and credibility.
Businesses hugely benefit from faster time to market, increased productivity, high availability, high scalability, IT cost optimization, seamless migration between multi-cloud environments and many more. Most importantly, it makes your business future-proof.
