Replication Controllers: These are frameworks that have specifically designed for the purpose of ensuring that, at any given moment, a certain number of pod replicas are scheduled and running.ĭocker Swarm has been a popular open source standard for packaging and distributing containerized applications.As a result, they can act as load balancers to direct traffic to run containers. Services: These are used to give names to Pod groups.Labels: These are key-value tags that are assigned to elements like pods, services, and replication controllers to identify them.Pods: These are a group of containers on the same node that are created, scheduled, and deployed together.For instance, tools like the Helm Project provide a uniform software packaging method that helps to extend version control and greatly simplifies the application distribution and deployment complexities.Ĭlusters in Kubernetes include several components like: Empowering the user with interfaces and composable platform primitives, Kubernetes allows high degrees of flexibility and reliability.Īlthough Kubernetes was known to be highly complex in the past, various tools and upgrades have gradually made it more user-friendly. It has the ability to automate deployment, scaling, and operating application containers.īy using Kubernetes, you will be able to define how your applications should run and the manner in which they interact with other applications.
In essence, it is an IT management tool that has been specifically designed to simplify the scalability of workloads using containers. Kubernetes has been developed by Google and it was introduced in the year 2014. This introduces many advantages to the equation, such as faster deployments, higher scalability, and closer parity between development environments.Īlthough there are multiple significant in the market when it comes to container orchestration, including Mesosphere and Amazon ECS, this blog aims to take a comparative look at two of the popular ones - Kubernetes and Docker Swarm. This is achieved through isolation that is executed at the kernel level without any need of a guest operating system. Hence, they allow developers to have more control over their products as compared to traditional virtualization. They help developers maintain consistency across various platforms, right from development to the production process. Containers have become quite popular in recent years.
