Introduction

Are you looking for a switch from IT operations to DevOps or a switch from development to DevOps? Well, you might as well get familiar with the top tools that dominate the scene in 2021. Here is a DevOps Tools list compiled after reviewing various factors like ease of use, ease of deployment, and popularity.

But if you are wondering what DevOps is after going through some of the internal job postings or on job websites, here is some information that will help you understand the role of DevOps in modern software development.

DevOps is not a particular software tool or even a clearly defined role, for that matter. DevOps, according to people in the know, is a culture that is in place to encourage smooth operation between IT operations and development teams and of finding ways to continuously improve the processes that fall in this bucket to achieve faster, better delivery of quality software. DevOps Tools are many times a collection of discrete software tools and sometimes a complete suite of tools working in tandem, all provided or even managed by a single vendor.

Each tool involved in DevOps has a specific purpose but has the potential to ease out any possible friction between IT Ops and Developer teams. A great example of a tool in DevOps is Git. Git is a version control system that democratizes development and puts the control in the hands of the developer as far as new releases and updates are concerned. Let’s now get into the actual DevOps Tools list we wanted to list out in the first place.

DevOps Tools List

  • Git

One of the most widely used tools in the DevOps technologies bucket is Git.

Git is a version control system that manages various versions and allows multiple versions from many development teams to be merged in a single update. Git allows free development without worrying too much about version control. Some of the features of Git are, Open Source and free, allows for decentralized development, support for the Pull request, enables Quick development, integration and release.

  • Jenkins

JENKINS is an open-source integration server with support for testing and reporting any changes. It makes the life of a developer much easier by helping in identifying bugs and rapidly code development. It also supports test automation. Jenkins supports around 1000 plug-ins that help you integrate with all stages of DevOps. With support for a wide range of version control software, including Git and a slew of plugins, Jenkins makes life easier for developers.

  • Selenium

Again, an open-source and free tool, Selenium is a software testing framework designed and optimised for web applications. Selenium is known for its easy-to-use interface that helps in creating automated test scripts. With Selenium, you can create browser-based regression testing automation suites. With support for a string of programming languages like C#, Java, Python, Ruby, PHP, Perl and JavaScript, Selenium is popular among developers and testers. Selenium also supports multiple platforms, including iOS, Android, Windows and Linux.

  • Docker

With container-based applications, there is hardly any load on the IT operations as far as setting up the right installation for the application. It is a lightweight tool and yet can scale up to 1000 nodes. Shipping the application along with a container makes it easier for developers to ship the product as quickly as possible.

  • Puppet

An open-source CM (Configuration Management) tool allows automating IT operations tasks like inspection, software delivery and operations through its entire life cycle independent of the platform. Puppet is based on a client-server or a master-slave architecture.

  • Chef

Another CM (Configuration Management) DevOps automation tool, chef an open-source software supports multiple platforms like AIX, FreeBSD, RHEL/ CentOS. It is a breeze to integrate Chef with cloud-based platforms.

  • Ansible

An open-source IT infrastructure automation tool makes it easy to automate applications and parts of IT infrastructure like network configuration and deployments on cloud and development environments. The most important feature of Ansible is that it is completely agentless. It also has a shorter learning curve with the script generated in YAML.

  • Nagios

Nagios is a very capable and powerful DevOps monitoring tool, helping in detecting and flagging out problems with the IT infrastructure well ahead. Nagios primarily monitors server traffic and performance issues. It can also automatically fix issues if they are found relatively less complex. Nagios can also help with the planning of IT upgrades for the future.

  • ELK Stack

Elasticsearch, Logstash, and Kibana (ELK) are a combination of 3 powerful tools used to collect, analyse, and draw inferences from your log data. The ELK stack is also an open-source tool and comes loaded with multiple plugins. ELK stack is easy to lightweight, and easy to deploy. IT can read through logs stored in flat file systems or excel-like documents or databases and draw inferences after analysis.

  • Splunk

Another tool to search, analyze log data from your servers, Splunk, also allows you to visualize this log data. Splunk is cloud-native and delivers its services through a web browser-based interface. Splunk also offers security based on predictive intelligence allowing it to be used for continuous monitoring.

Conclusion

The above list of tools is relevant for the current year and maybe for the next one to come. DevOps is a huge domain even for IT experienced folks. With the right guidance will keep you in the right direction in your pursuit of the most coveted roles in DevOps.
