DevOps is a combination of cultural principles, practices, and technologies that help organizations build high-speed applications and services, allowing them to innovate and enhance products faster than conventional software development and infrastructure management approaches. Because of this speed, businesses can better serve their customers and stay ahead of competitors.
Software and the Internet have altered the environment and industries we live in, from commerce to entertainment to finance. Software is no longer only a way of sustaining a corporation; it has become an integral part of all aspects. Companies engage with their customers with software that is available as internet services or applications that can be utilized on various devices. To improve operational efficiencies, they also leverage software to revolutionize every value chain component, including logistics, communications, and operations. Firms in today's environment must adapt how they produce and distribute software in the same manner that physical goods companies revolutionized how they designed, constructed, and delivered things utilizing industrial automation during the twentieth century.
Kubernetes, often known as K8s, is an open-source system for automating containerized applications' deployment, scaling, and administration. In essence, it is a container orchestration system. It enables organizations to automate and orchestrate key IT processes and thus helps streamline and simplify business operations. Orchestration means your application follows microservices-based architecture and is already containerized. However, to put these separate images together into a manageable production-grade solution, we need to run the application via the orchestration tools. You must maintain control over the containers that run the applications and guarantee no downtime. While there are other orchestration tools available, Kubernetes is the most popular one. It offers a unified API interface for managing even the most complex systems distributed across various servers and platforms. Kubernetes merely requires a broad outline of how you want your cluster to function. This framework is often a simple manifest file sent to Kubernetes using a command-line interface tool.
Kubernetes and DevOps are, without a doubt, the cloud's power duo! For businesses trying to create complex applications, they work hand in hand.
Today's software development cycles are getting shorter and shorter, but application sizes are growing larger and larger. Software developers and businesses are looking for a more straightforward solution. As a result, a technique known as DevOps was created to facilitate the development and delivery of software.
Its primary purpose is to integrate application development and operations across the software development life cycle, from strategy to planning, coding, building, testing, deploying, running, and monitoring. DevOps technologies automate processes and maintain configurations at a distinct level of configuration delivery. When the application grows tinier and more diversified, the real issue begins. So, how can DevOps assist in developing and delivering larger and more sophisticated applications to users?
To go in-depth, we need to add another tool, i.e., containers. Containers make hosting and managing the lifecycle of web applications in a portable environment much easier. It organizes application code and other dependencies into building blocks to provide consistency, efficiency, and productivity. Docker is a program that allows you to deploy containers inside a cluster and treat them as a single entity. However, the problem comes when deploying the multi-container application, several applications cannot coexist in a single container. What if you need to scale up your service to meet the demands of your business? What can you do to give services to several workstations without dealing with complicated network and storage configurations? Kubernetes was developed as a solution for this!
