Ansible and Kubernetes both refer to the category of automation tools. Each serves a distinct purpose in the development lifecycle of software. Ansible automates application deployment and cloud provisioning within the service. Whereas, Kubernetes is a platform that is used for automating management, deployment, and also scaling containerized applications. The primary objective of Kubernetes is to manage the cluster. Ansible is more useful to front-end developers, especially where programming is a must. While Kubernetes is used for developing larger applications. Though both are DevOps tools with a different purpose, they complement each other. Let us now understand the concept and explore the difference in brief!
Ansible is an IT software solution that is open-source and does not depend on the model of client-server. It is claimed to be the only automation tool (engine) that facilitates automation of the entire application cycle and delivers a continuous pipeline. Ansible makes production simple by increasing the speed by converting the difficult and time-consuming process to repeatable playbooks. It requires a Unix or Linux host as it controls the machine. It runs on many cloud platforms such as Atomic, AWS, Clouscale, Docker, and others.

Kubernetes is a CaaS(Container as a Service) project by Google. It is also an open-source, portable, and extensible platform to manage containerized workloads. It automates the container management’s operational tasks. The user can deploy, scale, monitor, and also roll out any changes in the application, making it easier to manage all the applications. Kubernetes popularly known as K8 orchestrates applications that are containerized to run on hosts.
Ansible and Kubernetes both are DevOps tools. Ansible is responsible for deploying changes to the host, while Kubernetes helps to manage the containers. Ansible configures systems and also organises complex functions of IT such as continuous deployment and rolling the updates while Kubernetes orchestrates the Docker containers.
Cloud server management is only possible with Ansible and not Kubernetes. Ansible cannot scale the development whereas with Kubernetes it is possible.
Flexibility : Ansible has more than 100 modules, therefore it is very easy & simple to customise the tool to fit the user's needs. The user can orchestrate the whole application environment irrespective of the place of deployment.
Zero Cost : The user does not have to bear any charges as it is a free open-source solution.
Simplicity : To use Ansible’s playbooks the user does not require coding skills. It's very easy to set up. All you need is to run one shell script and you can go with it.
Easy to use Playbooks : The user can easily edit and read the playbooks since most of them are in YAML format.
Efficiency : No additional software is required for Ansible. Therefore you can dedicate the resources to other applications.
Agentless Installation : Ansible can be set up within a couple of minutes by using OpenSSH. There is no need to set up remote servers or any agents.
Flexibility : Kubernetes, is a tool that is cloud-based as well as open-source. It is portable. It also offers numerous environment flexibility i.e the user can run it on hybrid clouds, public clouds, and also on premise servers.
Zero cost : The user does not have to shell any cost as it is available freely.
Process Automation : Since Kubernetes help is managing the containers. Its automation tools help in deciding the server that will host any given containers from the set of containers.
Self Monitoring : One of the primary features of Kubernetes is self-monitoring. It stays vigilant. It maintains the health of the container by keeping a check on the servers.
Storage orchestration : Many storage systems can be integrated with Kubernetes. For instance, the user can also combine with an AWS Elastic file system.

Kubernetes and Ansible both are simple and easy to use. Both tools help in application deployment. They cannot be compared as each has its purpose but they complement each other. Ansible is more suited for smaller projects where flexibility and automation play a huge role over complexity and scalability and vice versa for Kubernetes. Hope the article has helped you with a comprehensive introduction to both the tools. You are free to post comments in the section below for any queries.

Ansible helps in container building, cluster management, and also application cycle. It is difficult for Kubernetes to manage the application’s entire lifecycle. Hence Ansible is required to leverage Kubernetes.
Yes, Ansible can run on Kubernetes. The user will have to follow the below-mentioned steps for it.
Kubernetes manages all the applications that are containerized where you can term the container as a lightweight machine. The user will have to build a few containers and then leverage Kubernetes to manage these containers. Thus Kubernetes is an automation tool that creates and scales the containers and manages them simultaneously.
IT automation is the primary objective of using Ansible. Continuous deployment, Infrastructure provisioning, application development, configuration management, and others are a few more uses of it.
There are two sides to a coin, and so does Kubernetes. A few of the pros are:
Ansible manages the Kubernetes application with the help of the Kubernetes collection for Ansible. This allows a developer to use their existing Kubernetes existing file which is written in YAML or the user can express lifecycle management in the native Ansible
The use of Ansible will provide a repeatable, simple, and defined state of the container which can be tracked for any faults or errors in containers. Whereas, Kubernetes helps to manage the containers to run the applications.
