Introduction to DevOps
DevOps is a set of guiding principles for automating your company's whole development process by fusing software development and IT operations. Many firms use it frequently because it makes it possible to supply high-quality software continuously. Now, to make all the stages work efficiently, DevOps Engineer uses some tools at every stage of the DevOps Process. There are many tools, out of which we have mentioned some top DevOps tools that can make the whole process possible.
Top DevOps Tools
So, the first Top DevOps tools 2022 that we are going to look into is GIT.
Version Control Tool: Git
Git is a tool that is the most widely used tool in a development era to track multiple changes characterized by dynamism and collaboration. Git is one of the greatest version control systems for many reasons. Version control gives developers a way to keep track of all the updates and changes in their scripts so that in the event of an error, it is relatively simple to go back and use the earlier versions of the code.
It is so easy to implement because it supports most of the popular protocols like HTTP, SSH, and FTP. In contrast to the majority of other centralized version control technologies, it provides the best advantage for non-linear shared-repository development projects. This makes it an excellent value for software that is mission-critical.
Most of the time, developers do not have copies of the codes they submit to the central server. The other developers were unaware of any source code modifications they may have done. Additionally, none of the developers were in contact with one another. But Git addressed every issue. Every developer can have a complete copy of code on their own systems thanks to GIT. Additionally, anyone can follow any modifications that are made to the source code. The developers talk to one another frequently. Even they have the ability to reverse code modifications.
If we look at the features:
GIT is a Free Open source Tool, it allows distributed Development. It even supports pull requests and enables a faster release cycle.
Microsoft, Amazon, Facebook, and LinkedIn, are some companies using GIT.
Continuous Integration Tool: Jenkin
Jenkins comes second in the DevOps tools list. Jenkins is a continuous integration server built on Java. It can be used for testing and almost-instantaneous change reporting. One of the top DevOps tools available will help a developer quickly find and correct coding issues as well as automate build testing. It is the fastest and most practical method for a developer to correct mistakes.
In terms of functionalities, Jenkins is a free open-source program. Utilizing the roughly 1000 plugins that are available, helps to integrate all of your DevOps stages. Additionally, it incorporates one or more build jobs into a single pipeline script workflow. You may start your Jenkins server quickly by using only a WAR file.
Jenkins provides a range of communication channels, including a GUI, a CLI, and a REST API, which is one of its other excellent advantages. Some Companies that already use Jenkins include LinkedIn, OpenStack, and AngularJS.
Observability And Monitoring: Splunk
Splunk is a software platform that facilitates the searching, analyzing, and displaying of machine-generated data or logs gathered from many websites, applications, devices, and other elements of your IT Company. It is a monitoring and research platform that provides operational information to DevOps teams by providing real-time insights into the whole delivery lifecycle.
It raises the standard and boosts the effectiveness, security, and competitiveness of organizations. Some of the main features of Splunk are:
In Splunk insights and analytics get powered by data. It gives solutions for problems related to monitoring and troubleshooting. Excellent user experiences are provided by the Splunk Observability Cloud. Different file types can be used to store data. In order to gather log insights, it also creates operational intelligence knowledge objects and monitors business metrics.
Testing Tool: Selenium
Selenium is one of the top DevOps tools for testing. Here are some selenium test suites:
- Developers can build test scripts directly in a variety of computer languages using the Selenium client API as opposed to first writing them in the Selenese programming language.
- A smart proxy server called Selenium Grid enables tests to run simultaneously across several browsers and operating systems.
- Java-based Selenium Remote Control server transmits Selenium commands to web browsers for execution.
- Oracle, TCS, and Dell are some of the companies already using Selenium.
Configuration Management Tool: Puppet
Puppet is a simple but very powerful management DevOps tools 2022 that enables developers to centralize and automate the configuration management procedure like inspecting, delivering, and running your software across its entire lifecycle.
The star feature of Puppet is that it is based on master-slave architecture.
- It is an Open source tool
- It is scalable and can work cross-platform
There are some other reasons as well which Puppet can be widely used:
Some big companies like Cisco, JP Morgan, Accenture, and Flipkart are already using this tool.
Configuration Management Tool: Chef
Chef is a Configuration management (CM) powerful automation tool that enables developers to transform infrastructure into code. Starting from deploying, repairing, and updating to managing servers and applications in any environment, Chef can do it all.
Ansible, Chef, and Puppet are useful CM automation frameworks. Ansible is a Python-based framework, whereas Chef and Puppet are Ruby-based frameworks.
Chef can also be integrated with cloud platforms like AWS, Google Cloud Platform, Open Stack, etc.
If we look into the features,
then Chef can easily manage hundreds of servers with a handful of employees.
It maintains a blueprint of the entire infrastructure.
Moreover, it supports large deployments.
HP, firefox, and Disney are some of the big companies using Chef.
Configuration Management Tool: Ansible
Ansible is very easy to use, also it is strong enough to automate complicated multi-tier IT application settings. It is an automation engine used for a variety of IT operations, including development environment setup, cloud deployment, and configuration management.
Speaking about Ansible's primary attributes, it is a tool that expedites the development process. It employs basic syntax created by YAML and is entirely agentless. Additionally, it simplifies the software development process and removes complexity. Oracle, Cognizant, NASA, and Capital One are some of the companies using Ansible.
Container Platform: Docker
A crucial component and one of the most important DevOps tools of 2022, the Docker tool was created to keep developers and system administrators in mind. With Docker, developers can concentrate on creating applications rather than worrying about the platform on which they will run.
It is a compact tool that encapsulates an application in a container. Docker makes it simple to package up an application's various components, including libraries and other dependencies, and send it out as a single package.
A developer may be certain that the application will be delivered on time, thanks to package delivery, and can stop worrying about the platform's design and setup. By doing this, the size of the application is drastically decreased, and the performance of the application is enhanced at the time of delivery.
If we look into the key features of Docker then:
- With Docker, you can Ship the container wherever you want, be it QA, or even the cloud
- Another fantastic fact about Dockers is that it is an open-source tool.
eBay, Uber, and the New York Times are some of the companies using Docker.
Continuous Monitoring Tool: Nagios
Nagios is a powerful monitoring system that is used for monitoring networks, applications, and servers. Nagios software runs periodic checks on critical parameters of application, network, and server resources.
Nagios is a popular tool that can alert technical staff of the problem, allowing them to begin remediation processes before they affect critical business processes.
Nagios is a widely used tool as it:
- Monitors and troubleshoot server performance issues
- Helps you to find the root cause of the problem which allows you to get a permanent solution to the problem. It can automatically fix problems in a panic situation.
- Yahoo, Toshiba, Sony, Oracle, and Wipro, are some of the companies already using Nagios.
Container Platform: Kubernetes
Kubernetes is the container management system that allows organizations to create an automated, virtual, microservices application platform. By using these container services, organizations can build, deploy, and horizontally scale lightweight applications across multiple types of server hosts, cloud environments, and other infrastructures more efficiently. It also allows teams to automate the manual processes that are involved in orchestration.
Here are some main features of Kubernetes:
- The rolling updates and automated rollback features of Kubernetes allow the deployment of new releases with zero downtime.
- It even offers self-service catalog functionality that enables the creation of on-demand infrastructure by developers.
