Containers, Kubernetes and DevOps

What is DevOps

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 look for solutions for a simple, more effective process. DevOps comes out as a solution by introducing an agile approach to IT processes.

Why use DevOps

Speed

Move at a high velocity so you can innovate for customers faster, adapt to changing markets better, and grow more efficiently at driving business results. The DevOps model enables your developers and operations teams to achieve these results. For example, microservices and continuous delivery let teams take ownership of services and then release updates to them quicker.

Rapid delivery

Increase the frequency and pace of releases so you can innovate and improve your product faster. The quicker you can release new features and fix bugs, the faster you can respond to your customers’ needs and build a competitive advantage. Continuous integration and continuous delivery are practices that automate the software release process, from build to deploy.

Reliability

Ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining a positive experience for end-users. Use practices like continuous integration and continuous delivery to test that each change is functional and safe. Monitoring and logging practices help you stay informed of performance in real-time.

Scale

Operate and manage your infrastructure and development processes at scale. Automation and consistency help you manage complex or changing systems efficiently and with reduced risk. For example, infrastructure as code helps you manage your development, testing, and production environments in a repeatable and more efficient manner.

Improved Collaboration

Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows.

Security

Move quickly while retaining control and preserving compliance. You can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques. For example, using infrastructure as code and policy as code, you can define and then track compliance at scale.

Containers and Kubernetes

DevOps intends to unify 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. When the applications become more micro and diverse, is where containers and Kubernetes come into play.
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 resources. K8s supports a microservices architecture where apps that perform specific tasks can be quickly and easily scaled up or down as needed. The orchestration is handled by K8s based on user-defined workflows.

Why is Kubernetes important for DevOps?

Kubernetes allows developers to share their dependencies and software with IT operations, 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. It can streamline building, testing, and deploying pipelines in DevOps Managed Services.

How Kubernetes 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. 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 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.
Kubernetes offers a container-based integration ecosystem that is continuous and autonomous. They provide 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 pipelines and new loads as code modules, which can be distributed across various projects.
Kubernetes enables developers to obtain instant feedback 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 mishap efficiently. An application that is down can suffer hefty loss. 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. Kubernetes promotes server usage efficiency, thereby ensuring that you do not increase or under-do the load.
The quick delivery of software with improved compliance. Kubernetes facilitates continual enhancement and enhances collaboration and transparency across the team(s) that are responsible for delivering the software. They effectively reduce development costs and security risks.
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.
