Kubernetes is a go to tool these days, even among AWS users. The cloud giant already provides a really capable container management solution in Amazon ECS, but its open source counterpart has picked up a lot of steam over the last couple of years.
Which opens up the really interesting question of which solution to opt for if you are using the Amazon cloud for your apps and workloads. Both offer their own imposing benefits, and both are notably robust and reliable when it comes to usage.
Catch up on all the fancy magic that Kubernetes offers here.
Basically, Kubernetes takes the software encapsulation provided by Docker to the next level, by introducing Pods. A Pod is a collection of one or more Docker containers with single interface features like networking at a Pod level rather than at the container level. A Pod could consist of one or more containers, and has a single filesystem and IP address, with containers in the pod sharing these.
Kubernetes also introduces labels, that allow services and replication controllers the ability to identify or select the containers or pods that they manage. In essence, Kubernetes is not only lightweight and portable, but also modular.
Making it ideally suited for use in cloud architectures.
With the definition and working of Kubernetes clear, let’s get down to the most important question here. That being, how does Kubernetes compare against Amazon ECS? Are there distinct enough benefits of choosing one over the other? Particularly, when developing on the Amazon cloud?
The only real issue with the EC2 Container Service is that it is coupled to AWS.
What this means is that you can’t run an ECS cluster on other cloud providers. This makes sense, since this is an Amazon technology. And being native actually ties into a very strong point in favor of ECS, which is that it is completely integrated with other AWS components like VPC, EC2, ELB and Route 53.
Kubernetes, meanwhile, is independent, just like Docker.
And although every container orchestration framework uses its own specific language for its concepts, at the end of the day, they are all designed to solve the same issues.
There are a lot of similarities between the Amazon EC2 Container Service and Kubernetes, and deep diving into each will help you with your decision on which one to choose. Both offer their advantages, and both are uniquely impressive in their own right.
