Kubernetes and DevOps have turned out to be a power couple of clouds. Both run hand-in-hand for companies that contemplate developing sophisticated software and applications. But, DevOps and Kubernetes are not really related, right? So, how is this integration possible?
Let's dive into DevOps and Kubernetes and how this integration contributes to the enhanced efficiency of DevOps operations.
Application size, requirements, and complexities are growing bigger and bigger. On the contrary, the 'time to delivery' and software development cycle are getting shorter and shorter. Software companies readily looking for solutions for a simple, more effective process; DevOps comes out as a solution by introducing an agile approach to IT processes.
It intends to unify Java application development by automating tasks and managing configurations, thereby contributing to the software development lifecycle in terms of planning, strategy, building, coding, testing, deploying, launching, and monitoring. But, the real hurdle arises when the applications become more micro and diverse. Here is where containers and Kubernetes come into play.
Containers and Kubernetes
Simply put, a container is a portable environment that simplifies the hosting and managing of the life cycle of web applications. It is designed to deliver efficiency, productivity, and consistency. Although containers and DevOps are different in terms of concepts, they are part of the same conversation.
Kubernetes is an open-source container orchestration platform that supports numerous containers to work together, thereby reducing operational load. Features of this platform include rolling deployment, auto-scaling, volume storage, and computer resource. It can run in a data center, or in a public, private, or hybrid cloud.
So now, the question is, how Kubernetes can be helpful to DevOps? Kubernetes allows developers to share their dependencies and software with IT operations; thus, it reduces workload and resolves contradictions between several environments. It enables developers to respond to customer requirements while depending on the cloud for a load of functioning applications.
All in all, Kubernetes helps simplify container tasks, including rolling updates, canary deployment, and horizontal auto-scaling. Thus, it can streamline building, testing, and deploying pipelines in DevOps Managed Services.
Here is how Kubernetes can empower DevOps processes.
While writing, testing, or deploying an application inside a container, the atmosphere at different delivery parts does not change. This simplifies the collusion between various teams involved in the process, such as developers, admins, and testers. Thus, it allows the team to work in the same environment.
For continuous software delivery, application updates need to be rolled out on a consistent and streamlined basis. Since container orchestration is easy to apply, Kubernetes can help with updates to the application. If your application is segregated across multiple Microservice, all of them are deployed in different containers. Therefore, the updates can be performed in one part of the app by restarting the container and not bothering the rest of the application.
When containers follow the DevOps approach, they can quickly switch between various deploy platforms and frameworks. This functionality is offered because container orchestration is skeptic towards languages and platforms, so any kind of application can run within the container.
Also, it simplifies the process of moving containers between different types of host systems. For example, if you want to migrate from Ubuntu to Red Hat, you can do it easily with containers.
Kubernetes offers a container-based integration ecosystem that is continuous and autonomous. Thus, it provides the capability to scale up or down the application based on requirement and burden. This nature of the environment ensures immediate feedback once you make a commit to the repository.
Kubernetes with DevOps also reduces the time taken to built-in new projects. It can now contain reusable pipeline and new loads as code modules, which can be distributed crosswise various projects.
Kubernetes enables developers to obtain instant feedback on their builds without waiting in queues. The pipeline offers necessary productivity, efficiency, and convenience that allows developers to define CI configurations apace with code in the same depository.
Manually managing infrastructure operations can be a burdensome task for developers and coding teams as no one will be able to catch a mishappening efficiently. Problems like unanticipated traffic upsurge and power outages can emerge. For such cases, an application that is down can suffer hefty loss. But, Kubernetes enables you to automate and update patches to overcome such hurdles.
If your applications are not efficiently packed on the servers, you might end up overpaying for the heavy load. This is applicable irrespective of whether your application is deployed on the cloud or on-premise. Kubernetes promotes server usage efficiency, thereby ensuring that you do not increase or under-do the load.
Although Kubernetes offers a plethora of benefits, there is a challenge that turns the scenario. Kubernetes is complex and hard to set up and use; you will need a highly-skilled resource to manage it. To someone who is not familiar with containers or Kubernetes in particular, the setup might look simple and easy to implement and run.
But in reality, you will require additional functionality such as maintenance, backups, and disaster recovery to make it production-ready. Therefore, if you are contemplating opting for Kubernetes, make sure you have the highly skilled resources to give an edge to your organization.
Kubernetes is one of the best picks for ensuring continuous delivery while keeping the process agile. However, an organization must understand how DevOps and continuous development process helps to enhance the end-user experience.
All in all, Kubernetes has definitely changed the way applications and developed, deployed, and shipped by delivering what actually matters. However, using Kubernetes is a hassle, and an organization should consider the requirements and challenges while using this platform.
