In the DevOps world, there are a lot of tools available in the market. However to achieve faster application delivery, right tools must be used in the Devops infrastructure. We will look into some useful DevOps Automation tools in this article.
Useful DevOps Automation Tools:
There is no single tool which fits all your needs such as server provisioning, configuration management, automated builds, code deployments and monitoring.
DevOps tools can be categorized based on the layer of Automation you choose. Each layer has its own tools to build Automation.
|Configuration Management||1) Ansible
|Continuous Integration||1) Jenkins
|Continuous Deployment||1) Docker
|Continuous Monitoring||1) New Relic
Check out some useful DevOps Automation tools below.
Ansible is an open source, powerful automation software for configuring, managing and deploying software applications without any downtime just by using SSH. It’s easy to use, flexible, cross-platform, and also highly scalable.
Today, most of the IT Automation tools runs as an agent on the remote host but ansible just needs an SSH connection and Python (2.4 or later) to be installed on the remote nodes to perform it’s action.
In Ansible, the configuration modules are called as “Playbooks”. Playbooks are written in YAML format and it is relatively easy to write when compared to other configuration management tools.
Chef is a free and open source configuration management tool written in Ruby. It can easily be integrated with cloud-based platforms such as Amazon EC2, Google Cloud Platform, OpenStack and Microsoft Azure to automatically provision and configure new machines. It is suitable for small-scaled project to large enterprise level projects. Chef works on the configurations called “recipes” and those groups of recipes are called as “cookbook”.
Like Chef, Puppet is also an open source configuration management software which is written in Ruby. While chef cookbooks are more developer-centric, the puppet is developed by keeping system administrators in mind. Puppet is used from a small startup to large enterprise companies and organizations like Intel, NASA, Verizon etc.
All the required configurations are defined in files called Puppet manifests. Puppet runs a puppet agent on all server to be configured and it pulls the compiled module from the puppet server and installs required software packages specified in the module.
Saltstack is based on Python and it offers a push method as well as SSH method of communication with clients. Normally in chef and puppet, the code for configuration will be pulled from the server while, in Saltstack the code can be pushed to many nodes simultaneously. The compilation of code and configuration is very fast in Saltstack.
Jenkins is an open source tool written in Java. It provides a continuous integration services for software development. It also helps to test the software and make sure no bugs are introduced. Jenkins has to be associated with a version control system like GitHub or SVN. You can easily configure Jenkins to build code, create Docker containers, run tests and push the changes to the production environment.
Docker is an open-source program that enables a Linux application and its dependencies to be packaged as a container. These containers can be shipped to any other server without making changes to the application. Docker is so lightweight and considered to be the next step in virtualization.
Vagrant is a free and open source software that is widely used for creating and configuring one or multiple virtual development environments on top of other virtualization technologies like VirtualBox, Linux Containers, VMware and AWS.The Vagrant images also known as boxes can be imported, exported and run from one computer to another. These days, many software’s are pre-loaded in a Vagrant box making it easy for the deployment of the product.
