What is the advantage of Kubernetes?
From our previous experience with k8s container management tool, we distinguish the following reasons to use Kubernetes:
How is Kubernetes different from Docker?
- mature and reliable underlying architecture
- great industry support and ongoing development by contributors
- wide range of feature sets and application support
- supports many types of workloads, programming languages and frameworks
- workload scalability
- high availability
- declarative configuration
- self-healing system
- reducing resource and maintenance costs
- automation of almost all manual processes
- storage orchestration
Docker and Kubernetes can sometimes appear to be almost the same technologies. Yes, they both were developed to run applications within Linux containers. BUT these technologies operate in different layers / stages of the stack and even used together.
Docker helps you create and deploy software and applications within the containers.
Thus, it is the initial step towards containerization - just create and orchestrate containers.
Another deal if you need to manage containers - here comes Kubernetes to help you.
So the containers created in Docker are managed with Kubernetes. Docker has its own native container management tool called Docker Swarm
.Is Kubernetes free?
Yes. Kubernetes is free and can be downloaded from its repository on GitHub.Which is best Docker or Kubernetes?
As we described above, Docker and Kubernetes are not the same technologies and cannot be compared.
If you mean Docker Swarm as the native container orchestration tool, we recommend using Kubernetes despite the fact that it can be a sometimes challenging task to implement k8s to the existing infrastructure.Why do I need Kubernetes?
It is really hard to imagine a modern and cloud-native infrastructure without containers. Even if you have a kind of simple app (with no highloads and many dependencies) you will need to have the applications and services containerized to operate smoothly and seamlessly in any cloud.
