Kubernetes is a fast growing technology benefitting organization with its wide offerings and effective usage. Customers are building different application over Kubernetes resulting in an increased deployment size. Several cloud vendors offer solutions for Kubernetes and build server-less Kubernetes which helps in eliminating complexities as it continues to use APIs and tools. It has built an open source community across the globe that leads to a notable increase in Kubernetes adoption with heavier workload this year. By the end of 2019, we will be able to see few key players adopting the server-less Kubernetes even before it takes off in 2020.
Kubernetes is a portable open source container orchestrator which predominantly focuses on automating deployment, scaling and application management. We invariably use it in large-scale enterprises to execute critical tasks.
Kubernetes’ effect on DevOps
The developers’ team tends to share their software application and dependencies with the operations team reducing complexities in the platform and workload. It helps in eliminating the problems quickly making it hassle-free for the teams to collaborate. It has eradicated the manual tasks of scaling containerization and deployment of application for better reliability during environment switch.
For example, when we schedule number of containers in a node, Kubernetes manages as many containers and workloads as possible. Further, it helps in simplifying tasks like scaling, rolling over updates and deployments.
Kubernetes enables DevOps by
- Automating container deployments
- Considering infrastructure as code wherein parts of application like ports, databases, repositories etc., can be used by Kubernetes to deploy and manage applications automatically
- Processing configuration as code where it stores the script files in the source repository and lets you choose file’s location and its usage
- Creating unchangeable new containers in case of problems with the position of virtual machine and to be aware of the environment configuration
- Allowing the developers to take resources they need yet controlling service configurations by operations team
- Checking for environment consistency to give an environment similar to production. This method helps us to find bugs in the development stage itself and not in production
- Aiding deployment with blue-green deployment approach consisting of environments and switching between them with zero downtime
Kubernetes impact on CI/CD pipeline
CI and CD process has the same target to achieve but the process towards it is different. It makes the release process faster and easier with tools like Jenkins as it automates the development cycle with respect to time, speed, quality ad procession. This improves elasticity, utilities and resource usage.
Benefits of Kubernetes
- Hassle-free solution: when we build an application and deploy in a container, the environments throughout the process is static which improves team collaboration.
- With continuous delivery, there are equivalent numbers of updates of an application and Kubernetes helps with this process. It helps in distributing the updates again into micro services where it deploys each one in an individual container. We can make the updates here without disturbing the other parts of the application as we restart the container.
- Kubernetes invariably supports multiple platforms with DevOps. It enables to build any type of application and deploy it into the containers. We can shift these containers to different host system
- It provides high scalability of the application with respect to load
- It aids in increasing developers’ productivity by reducing the waiting time for receiving feedbacks on builds.
- During any mishaps, Kubernetes readily automates patches, updates and solves the issues instantly.
- Kubernetes helps to increase the efficiency of the server so as to withstand any increase in load
- It increases transparency amongst the delivery team members.
- It supports in delivering the software quickly with better compliance and enhanced security at controlled cost.
Kubernetes- The best way to keep agile
Kubernetes involved with DevOps has changed the way software is developed and transported and hence, the increasing popularity of it is irresistible. With its ability to work in both public and private cloud, it has become the power house of organizations’ growth as it manages anything from hosting systems to production and moving business. Therefore, Kubernetes is the best way to keep agility in trend anyday.
