Stay Ahead with the Power of Upskilling - Invest in Yourself! 
Since DevOps is vast and bit complex. So, it might not be an easy thing at the beginning for a fresher to cope up with DevOps tools unless you have not used them before. But no need to worry, everyone is a fresher in the beginning of his/her career. You just need to set your mind and start preparing before setting your feet towards the DevOps path.
Why DevOps Testing job is a good career choice?
DevOps is exciting this is because you are always working with and integrating new technologies and solving new challenges. Essentially your job is to find a happy balance between Testers and developers. This relationship is quite sensitive and may blow up if not administered intently. As a DevOps specialist your job would be to amalgamate these two different mindsets.
This requires that aspects of IT be securely shared so that you don’t have the blame game Developers need to continually push code and operations want to keep everything running smoothly. The more integrated the systems and processes in use, the simpler it is for each to do his/her job.

Let’s just first understand where did DevOps Come From?
DevOps is the successor of agile software development – born from the need to keep up with the increased software velocity and throughput agile methods have achieved. Over the last decade advancements in agile culture and methods exposed the need for a more holistic approach to the end-to-end software delivery lifecycle.
What Are the Challenges DevOps Solves?
Initially to DevOps application development, teams were in charge of writing code and gathering business requirements for a software programme. Then in an isolated development environment a separate QA team tests the program, if requirements were met, and releases the code for operations to deploy. The deployment teams are further specked into safe groups like networking and database. Every time a software program is “thrown over the wall” to an independent team it adds congestion. The problem with this standard is that when the teams work separately:
- Dev is often unaware of QA and Ops roadblocks that prevent the program from working as foreseen.
- QA and Ops are typically working across many features and have little background of the business purpose and value of the software.
- So, when something goes wrong each group has opposing goals that can lead to inefficiency and finger pointing.
By establishing collaborative cross-functional teams DevOps addresses these challenges that share responsibility for maintaining the system. Those run the software and prepare the software to run on that system with increased quality feedback and automation issues.
Thus DevOps is one of the most interesting career paths but to reach there you need to have certain skills. Which are discussed below.
Skills required for DevOps Testing job
DevOps plays an essential role in providing automation in the area of Build, Testing and Release to project teams. Which are today normally termed as Continuous Integration, Continuous Testing, and Continuous Delivery.
That’s why teams today are looking at faster delivery, quick feedback from customers. While providing quality software, less recovery cycle time from any crashes, and minimize defects from more and more automation. Therefore, one needs to ensure that with all the tools used and about the Integrations for the Testing and Operations team to collaborate or communicate later.
Here we have enlisted a few tools for DevOps Testing
Monit
Sometimes the simplest tools are the most useful of all, as proven by the simple watchdog Monit. It ensures that any given process on a machine is up and running appropriately. For instance, if a failure occurs in Apache, Monit will help to restart the Apache process. With hundreds of micro-services it is very easy to setup and configure and is especially useful for multi-service architecture. If you are using Monit, ensure to monitor the restarts that it executes in order to surface problems and implement solutions. You can do this just by monitoring Monit’s log files and ensuring that you are alerted to every restart.
Consul.io
Consul is a great fit for service discovery and configuration even so, in modern, elastic applications that are built from Microservices. This open-source tool utilizes the latest technology in providing internal DNS names for services. Furthermore, it acts as a kind of mediator to help you sign and register names, enabling the access to service names instead of specific machines. For instance, if you have a cluster of multiple machines, you can simply register them as a single entity under Consul and access the cluster easily.
Jenkins
This is quite a well known tool although not the fanciest of all or the fastest. Still very easy to start to use and it has a great ecosystem of plugins and add-ons. It is also optimized for easy customization. We have configured Jenkins to build code, create Docker, run tons of tests, and push to staging/production.
Ansible
This is an open source IT Configuration Management, Deployment & Orchestration tool. It sights to provide large productivity gains to a wide variety of automation challenges. This tool is quite simple to use yet powerful enough to automate complex multi-tier IT application environments.
Collectd/Collectl
Collectl is a very nice feature rich command-line utility that can be utilized to collect performance data that describes the current system status. Unlike most of the other monitoring tools, it does not only focus in a limited number of system metrics. Instead it can collect information on many different types of system resources such as- CPU, disk, memory, network, sockets, IIfiniBand, lustre, memory, nfs, processes, quadrics, slabs and buddy info.
Advantage over using collectl is that it can also play the role of utilities that are designed with only a specific purpose such as- top, ps, iotop and many others.
Git (GitHub)
It was created 10 years back following the Linux community’s need for SCM that could support distributed systems. Git is probably the most common source management tool available currently. After regulating Git internally for a short period of time, it’s been noted that GitHub was better suited. Furthermore to its great forking and pull request features, to facilitate integration and deployment GitHub also has plugins that could connect with Jenkins.
GitHub offers plans free, for both professional, and enterprise accounts.Free GitHub accounts are commonly used to host open source projects.
Along with the knowledge of the required tools you may also take training/certification courses. There are numerous certification bodies offering courses for DevOps Testing, to enrich your skills and improve your chances of getting hired for the best available opportunities.
There are different certification bodies offering the courses-
- The DevOps Institute
- Vskills- India’s largest certification body
- Edureka
- Udemy
- Simplilearn
