THE 5 CONTAINER ORCHESTRATORS YOU SHOULD KNOW ABOUT
The 5 Container Orchestrators You Should Know About
If you have or want an infrastructure with Dockers, based on microservices architecture, and you need it to be scalable, you may already be using an orchestrator. Otherwise, it is a good time to choose one. Also, in this article you can get a free official certification in Kubernetes and OpenShift for free!
Currently, most of the infrastructures of medium and large companies work with Dockers in their systems. To improve their management, these architecture and/or DevOps teams use orchestrators, depending on the system, to improve: automation, deployment, scalability, load balancing, availability, and the container networking system.
But among all these container managers, which ones should we take into account?
Kubernetes
Kubernetes, or K8s, is an open source platform, originally designed by Google and now maintained by the Cloud Native Computing Foundation. It is the most popular platform for Dockers orchestration. The main benefit of using Kubernetes in your environment is that it gives you the platform to schedule and run containers on clusters of virtual or physical machines.
With Kubernetes you can:
- Orchestrate containers across multiple hosts
- Make better use of hardware to maximize the resources needed to run your business applications
- Control and automate application deployments and updates
- Mount and add storage to run stateful applications
- Scale containerized applications and their resources on the fly
- Manage services declaratively, ensuring that deployed applications always run the way you deployed them
Open Shift
While we’re back to talking a bit about Kubernetes, “Red Hat OpenShift Container Platform is an enterprise Kubernetes container platform, with end-to-end automated operations to manage multicloud and hybrid cloud deployments.” The differences that we could find with a solution with only Kubernetes would be:
- Operating System: Openshift only with Linux, Fedora and CentOS
- Security: Co Kubernetes is in the user’s hand
- CI/CD: integrated in Openshift
- Scalability: Openshift for enterprise projects
- Networking: in Openshif we would use Open v Switch
Docker swarm
It is a tool built into Docker that allows you to group a number of Docker hosts into a cluster and manage them centrally, as well as orchestrate containers.
Its advantages would be:
- Integrated with the Docker Engine API
- Redistributes workloads if there is a node failure. This ensures high availability.
- Manage container groups
- Possible manual scaling and rolling updates
- No additional configuration is required to use it with docker
DockerCompose
It is a tool that simplifies the use of dockers from YAML files, in addition to the possibility of using it on Windows, unlike other container manager systems.
Characteristics:
- Multiple sandbox environments on a single host
- Preserve volume data when containers are created
- Only re-create containers that have changed
- Variables and movement of a composition between environments.
Cloud-based: GKE, ECS, EKS, AKS
Within the most important cloud providers AWS, Google Cloud Platform and Azure, we can find the solutions they use for container orchestration:
- AWS: ECS, EKS, Fargate
- Google Cloud: GKE
- Azure: AKS
It will be interesting to analyze them in the event that we are using one of these Cloud providers for our infrastructure. In addition, the compatibility they have with Kubernetes.
