DevOps is an approach that combines software development (Dev) and Information technology operations, which enables organizations to deliver software releases and new changes to users in a rapid environment with the help of automation. A wide variety of DevOps tools are available in the market as the prerequisites of every specific DevOps requirement. Deciding on the right set of tools is an ever-growing challenge for the stakeholders. Furthermore, we recommend that a single tool may not be a full-fledge solution to a DevOps adoption.
Let’s have a look at the 20 best DevOps automation tools that can dominate the software industry in 2020.
Puppet Enterprise is the most advanced cross-platform configuration management tool that is used to configure, deploy, and manage servers to make the deployment faster and secure. It configures each and every host in your infrastructure and manages the servers by scaling up and scaling down the machines dynamically. Puppet continuously checks whether the configuration is in place or not. If not, it reverts the required configuration on the host.
Puppet has a master-slave architecture. Communications are typically done through a secure encrypted channel over SSL. It automates infrastructure management by treating the entire infrastructure as code.
Puppet Enterprise enables you to manage multiple teams and resources. It is also capable of handling disasters smartly. It has several modules that can be integrated with many other popular DevOps tools very quickly.
Docker is a well known DevOps technology suite that allows DevOps teams to build and run distributed applications fast and efficiently. It works on the concept of virtualization at the process level. Docker creates isolated environments for container apps to eliminate the conflicts between the apps. Isolating applications into separate containers makes applications portable make them more secure as well.
Docker provides flexible image management. It maintains a private registry to store, manage images, and to configure image caches. Docker allows you to all together create your own images or to modify the current ones as per the requirements. Docker is the first one that has made containerization popular in the IT world. It facilitates faster deployment, makes distributed development possible, and automates the deployment of the apps. Docker apps are OS and platform-independent and easily integrated with cloud computing. All popular cloud providers like Google and AWS have added support for Docker.
Jenkins is a CI/CD automation tool for monitoring the execution of repeated tasks. It is open-source and written in Java and hence ready to run with any operating systems. It offers a number of built-in plugins for continuous integration, which is the most important part of DevOps. Jenkins CI/CD server allows you to automate various stages of your delivery pipeline.
It enables CI/CD for any combination of coding language and source code repositories using a pipeline system. Its Pipeline-as-code functionality makes the CI/CD pipelines a complete code and ensures integrating the entire DevOps chain. Moreover, Jenkins has around thousand plugins that helps to integrate all your DevOps stages efficiently.
Like Jenkins, Bamboo is also a CI/CD DevOps tool that allows automating the delivery pipeline, from builds to deployment.
Bamboo comes up with many pre-built functionalities, which need to be configured manually in Jenkins. This is why Bamboo has only around 100 plugin whereas Jenkins has more than 1000 plugins. In fact, Bamboo does need that many plugins as it has built-in features to perform out of the box tasks. Therefore, Bamboo can save configuration time a lot. Here is the basic difference between a paid software and its free alternative. Therefore, the selection of the tool depends on the budget and goals.
Bamboo effortlessly integrates with other popular products like Jira and Bitbucket. It also offers access to built-in Git and test environments. Moreover, its UI is more intuitive with tooltips, auto-completion, and other convenient features.
Terraform a cloud infrastructure provisioning tool in which the infrastructure is described using code. It generates a graph of all resources and creates and modifies any independent resources in parallel and maintain different versions. Terraform uses state files to maintain the state of infrastructure. It creates an execution plan where the steps of reaching the desired state is described and then executes the plan to build the described infrastructure. This way, Terraform facilitates the DevOps team to build and change infrastructure efficiently and in a safe manner with nominal human interactions. It efficiently works with both public and private cloud infrastructure.
Ansible is a fairly simple agent-less, easy to deploy configuration management tool that offers the continuous delivery feature enabling faster deployments. It automates application deployment, cloud provisioning, intra-service orchestration, and many other repetitive tasks. Ansible does not require further custom security infrastructure.
Ansible connects the nodes and pushes out small programs called modules to them. Then it executes these modules and removes them when the execution is complete.
Like Puppet, Ansible also considers the infrastructure as code. However, it uses YAML to describe the automation jobs in the form of playbooks. Being agentless, Ansible provides a faster, safe, and lightweight solution for configuration management automation because no agents or daemons run in the background. Thus it helps the DevOps team to speed up productivity.
Chef is a Ruby-based DevOps configuration management tool for web-scale IT operations. It deals with managing the infrastructure. Configuration management ensures that all the machines whether they are physical, virtual, or in the cloud and the files and software in the machines are correctly configured and working as expected. When the infrastructure is small, it can be configured easily and manually as well. However, when the infrastructure scales up, it requires a better alternative solution.
Chef comes up with a solution that treats infrastructure as code. Instead of manually configuring everything like databases, load balancing, and web servers, the configuration set up is described in a Chef recipe. Chef uses Cookbooks to store a collection of recipes. In Cookbooks, the infrastructure is coded in a domain-specific language.
Chef is a useful DevOps tool to speed up complex tasks and to perform automation. Many big companies use Chef to manage their data centers, cloud environments effectively. The high availability and replication features of Chef are capable of adapting and recreating the infrastructure as required if something goes wrong, thus ensures low downtime and high availability of machines with minimal human interventions.
Vagrant is a DevOps tool that emphases on automation. It works effortlessly on different operating systems like Windows, Linux, and Mac OS. Vagrant makes a single file for every project where the type of the machine and software that users want to install are typically described. It focuses on CI/CD deployment and helps the DevOps team to get a perfect development environment. It offers to configure virtual machine environments in a single, easy-to-use, and consistent workflow by decreasing the setup time and increasing production uniformity. Vagrant offers plugins to easily integrate with other popular configuration management tools, such as Puppet, Ansible, Chef, and Salt.
Git is one of the most extensively used DevOps tools across the software industry. It is the most favorite tool of the remote teams and open source contributors. It is a distributed source code management (SCM) tool that allows developers to track the progress of your development work by maintaining different versions of the source code. And they can easily go back to a previous version whenever required.
Git can be easily integrated with the DevOps workflow by using host repositories where DevOps team members can push their work. At present, GitHub and Bitbucket are the two best online Git repo hosting services in which GitHub is more familiar. While Bitbucket provides free unlimited private repos for a team of up to five members, GitHub provides free access only to public repos.
Nowadays, everybody is talking about Kubernetes, which container orchestration platform founded by Google. It manages containers at large scale and takes containerization to the next level. It works well in combination with Docker or any of its equivalents. With Kubernetes, containers can be grouped into logical units. Kubernetes allows automating the process of managing hundreds of containers.
Kubernetes facilitates to deploy containerized apps to a cluster of computers instead of a single machine by automating the distribution and scheduling of containers across the cluster.
A Kubernetes cluster works on the master-slave concept. The pre-defined rules are implemented on the master node and the containers deployed on the slave nodes. Kubernetes takes care of everything. Whenever a slave node is down Kubernetes redistributes the containers on the other nodes.
