Terraform and Kubernetes are very popular tools in the DevOps world which looks similar but they are quite different as
- They Serve different purposes
- They have Different areas of focus
Here are some of the key differences between Terraform and Kubernetes:
Purpose
Terraform is an infrastructure-as-code tool that allows you to manage cloud infrastructure resources such as virtual machines, databases and networking.
Kubernetes, on the other hand, is a container orchestration platform that automates the deployment, scaling and management of containerized applications.
Scope
Terraform is focused on managing infrastructure resources across multiple cloud providers,
Kubernetes is focused on deploying and managing containerized applications on a cluster of servers.
Abstraction level
Terraform operates at a lower level of abstraction, allowing you to define and manage infrastructure resources such as virtual machines, load balancers and databases.
Kubernetes operates at a higher level of abstraction, allowing you to define and manage containerized applications and their associated resources such as deployments, pods and services.
State management
Terraform maintains a state file that tracks the current state of the infrastructure it manages. This state file is used to ensure that changes to the infrastructure are made in a predictable and consistent manner.
Kubernetes maintains its state using etcd, a distributed key-value store that stores the configuration and state of the Kubernetes cluster.
Community
Both Terraform and Kubernetes have large and active communities that contribute to their development and support. However, the communities have different focuses and priorities.
The Terraform community is focused on managing infrastructure resources across multiple cloud providers,
Kubernetes community is focused on developing and improving the container orchestration platform.
To Sum up :
Terraform is an infrastructure-as-code tool that allows you to manage cloud infrastructure resources, while Kubernetes is a container orchestration platform that automates the deployment, scaling and management of containerized applications. Both tools have their strengths and are commonly used together in modern DevOps workflows.
