DevOps defines as a culture or movement of practices that focuses on the collaboration and communication between software developers and other IT professionals. Now we are done with the formal definition but it is quite difficult to give the true definition of DevOps because market dynamics are changing frequently with the emergence of new technologies.
We can’t say that DevOps is just another tool in the box. Agile and DevOps are almost similar and follows a similar software testing life cycle (STLC). There are a lot of open source DevOps tools and testing frameworks available that help organization for proper implementation of strategies.
Some Famous DevOps Tools list: (not limited to)
Jenkins, the open source continuous delivery and continuous integration platform. It is mostly targeted towards tasks covering continuous integration to drive business automation and deploying workflow. Jenkins was developed as the Hudson project.
Why is Jenkins so much popular? Jenkins has now become the standard open source for dev side management of DevOps, starting from source code management to delivering code to production. Jenkins usage includes building new projects, running tests for bug detection, and finally deployment.
Docker, the leading software platform dedicated towards containerization.It binds together everything that an application requires to run- the code, the runtime, system tools, libraries etc. Docker allows the applications to run in the same way no matter where they are deployed.
Docker has improved in the last couple of years and has become the first choice in software development and testing. Docker has made it easy for DevOps teams to configure dev/test environments. It has now become easy for DevOps teams because the whole application can be packaged as a Docker Image. Because of this, there is no need to deploy the final set of EXE and JAR files to target environment.
Docker recently conducted a survey and it was found that 80 percent of enterprise has planned their DevOps implementation around Docker.
Chef, the name of a company and the name of a configurational management tool written in Ruby and Erlang. Chef is widely used by some of the giant companies like GE, Facebook, Disney, Airbnb, and Mozilla.
Chef automates the process of configuration, deployment and applications management. The process is done through repeatable scripts that have been given the name as “recipes”. These recipes together are called as “cookbook” and works as pluggable configuration modules.
Ansible is known for simplicity and is a tool used for configuring and managing computers along with automation services. It is similar to that of Puppet and Chef but, as said before is much more simple. Ansible includes multi-node deployment and ad-hoc task execution and manages nodes over PowerShell or SSH. The modules in Ansible works in both standard input and JSON and can be written in any language. Ansible is included as a part of Fedora distribution of Linux, which is owned by Red Hat. YAML data format can be considered as one of the reasons why Ansible is such an effective tool. Ansible also enables users to easily write custom applications.
Git is a free and open-source distributed control system which is designed to handle both large and small projects with speed and efficiency. Git even has plugins that can be used to connect with Jenkins in order to support deployment and integration. Git is small and fast when compared to the centralized systems which constantly communicates with servers because almost all the operations are performed locally. Git allows you to have multiple local branches which are independent of each other. Git can be used as a server, as it is a distributed version control system. Most of the operating systems are supported by Git even though it is developed on Linux.
- Amazon web services
AWS is a collection of cloud computing services which is offered by Amazon. Most recognized services include Amazon Simple Storage Service(S3) and Amazon Elastic Compute Cloud(EC2). Launched in 2006, AWS provides services for client-side applications and websites. AWS provides a broad set of infrastructure services which includes storage options, computing power, and databases. HTTP is used to access the offerings by AWS, using SOAP protocol and REST architectural style. All the services which are taken will be billed according to the usage and billing differs from service to service. AWS offers more than 50 services for various requirements.
Although the above-listed tools are some of the most used, there are many other open-source tools for DevOps. Further research on the topic is advised if you are planning to use these tools.
