Kubernetes to Ease Your Containerized Applications

You might have noticed these days that most of the professionals surrounding the software sector are chanting the word “Kubernetes” like a mantra, and it extends from the Developers and Operators to Managers and tech-savvy marketers. Have you ever thought about why this word has so much impact on everyone, and how it became the apple of a software expert’s eye?

How to Get Started with Kubernetes

Now you know it is very significant to know about the trending Kubernetes, the leading container management and service orchestration framework, to follow the latest technologies in the field. So, how to get started with this powerful concept?

Come, let’s begin from the foundation.

Much like microservices themselves, containers have been gaining wide popularity and ground in recent times as an inevitable part of the current scalable architecture.

Containerization is the most simplified approach to software development that provides a fine abstraction that separates the core component of your web services and wraps up the application libraries and dependencies into a single deployable unit. This resulted in containers to becoming lightweight, run, and scale independently.

The container management system follows a bunch of practices to govern and maintain the containerization software.

Containers not only provide matchless benefits to the software development process but also are reliable and aid companies remodel by making it easier to scale and deploy many applications, but they have also introduced new challenges such as more complexity.

Large and small software businesses alike are now deploying thousands of container instances day-to-day, making it more difficult. So how do they do it?

Enter the era of Kubernetes, the powerful and wildly popular container orchestration platform.

What exactly is Kubernetes?

What is Kubernetes? –  Indisputably, the first question you ask.

Kubernetes also referred as K8s, is an open-source container orchestration platform created to automate the deployment, scaling, and management of containerized applications across every infrastructure. It is fundamentally a technology to manage your containers, especially the Docker containers that really work well together with Kubernetes.

Simply, it’s a platform that assists your hand as you work through building and managing your containers.

How did Kubernetes originate?

Kubernetes may seem like new technology but actually, it was introduced in 2015 and is only rising in popularity. Isn’t that surprising?

Kubernetes emerged as a fragment of a core project called Borg, at Google, which echoed the years of combined practice with distributed systems.

In fact, Kubernetes has established a gold standard for itself, for container orchestration and is the star project of the Cloud Native Computing Foundation (CNCF), backed by chief players like Google, Microsoft, IBM, AWS, Intel, Cisco, and Red Hat.

As containerization technology was kick-starting, there were several competing technologies for managing large Docker deployments and container-based service areas. You may recall a few of those aged solutions: Apache Mesos, Docker Swarm, OpenStack Magnum, etc. Now, Kubernetes has eradicated the competition. It’s the only containerization solution accessible natively on Google Cloud, AWS, Azure, as well as many private cloud giants like RedHat and Pivotal.

Why Kubernetes?

As more and more establishments move towards microservice and cloud-native architectures that efficiently use the containers, they are looking for strong, and proven platforms. Experts are moving to Kubernetes for many reasons.

We are now going to untie the question “why Kubernetes” or “what makes it unique”. Yes, like you think, here onwards we will be exploring more on how Kubernetes has become the booming technology in this period.

Kubernetes grabbed so much acceptance very quickly because it was able to isolate configuration from orchestration. With Kubernetes, you can state how you want the service to look like, how many instances, the type of redundancy, and where the services are positioned. Then the tool estimates what changes require to happen to create that service from the current scenario. Think of it in resemblance to SQL, where you don’t specify how the database adds or alters each individual row. You just identify and specify how you want the data to look like, and the database works out how to get there. Kubernetes holds the same tactic.

Another captivating fact to use K8s is that, you don’t have to be concerned about each container’s or instance’s availability, if an instance flops, Kubernetes will auto-sense this and simply restructure the unsuccessful instance’s containers on another instance.

For K8s, we can undeniably say that a single containerization technology has taken off far above the others. It has simply made modern container-based DevOps, microservices, and containers go just like bread and butter.

Kubernetes works integrally with microservices, and paves an easy way to deploy and operate the basic, and even more complex microservices architectures, going hassle-free. So it’s good to have a clear idea of how they fit together and also, discover more on Kubernetes and Docker containers, the workhorse of the modern microservices operations.

Kubernetes works by creating an abstraction layer on top of a set of hosts so that development crews can deploy their applications and let Kubernetes achieve the following activities:

  • Controls and monitor the consumption of resources
    by application or team automatically stop consuming too much
  • Evenly shares the application load across a host
  • Automatically queues balancing requests across the several
    instances of an application
  • In case of shortage of resources in a host, or if
    the host dies, forwards an application instance from one host to another
  • Makes additional resources available automatically,
    while a new host is added to the cluster
  • Easily executes canary deployments and rollbacks

Kubernetes and DevOps

You do possess now a clear understanding of Kubernetes features, who use them, and where it can be applied.

Here, we’ll uncover a bit more benefits of it, specifically for DevOps.

What Kubernetes brings to the table is the facility to manage containers as a service definition. Kubernetes begin with just containers. Even if you’re just want to deploy a container without much stepping into the microservices world, Kubernetes has a lot to offer you regarding management and deployment. You can install the kubernetes software on servers in your cluster, and the master Kubernetes process will set up your software automatically.

Developers dwell blindly on containerization while deploying applications and give a little appreciation to Kubernetes, as Kubernetes is the reason containerization has harvested a mass acceptance among organizations. Kubernetes eases your life as a developer. This is exclusively relevant if your company insists on following DevOps practices and working on automated software delivery channels.

For DevOps players, kubernetes enforce developers more productive in union with containers, as it makes them proficient and set free from the load of redrafting software in order to move it to other cloud providers. Operators appreciate how radically it cuts the amount of time they employ deploying applications and scaling.

So, with Kubernetes, you can run apps better, rectify systems automatically, refine uptime, and make costs down and users happy.

Kubernetes saves establishments millions of dollars every year by letting them do more with fewer IT manpower and efficiently apply the infrastructure that powers their applications. Even the cloud giants with weighty pockets and immense resource pools have already widely adopted K8s for the huge benefits it offers.
