DevOps lifecycle has seven phases, each of them with its features and tools to use. Here is a list of the best tools for DevOps that allow you to create software faster with the best quality and provide quality IT service.
DevOps is a software process development methodology. It brings together development (Dev) and technical support operations (Ops) to improve performance through an automated system in the processes of released applications. DevOps assigns responsibilities to each participant through communication.

What is a DevOps Engineer?
A DevOps engineer is a specialist who implements a DevOps methodology in projects. He or she must know different areas, be both a developer and a manager, and also a tester and a technical support specialist. They must be familiar and skilled in all areas of information technology.
There are seven phases of DevOps optimization in the development processes. Each stage offers various DevOps tools, and here we outline the most common.
DevOps Lifecycle: Seven Phases to Optimize Development Processes
1. Continuous Development
The first phase of the DevOps lifecycle, continuous development, combines planning and coding. During the planning phase, you don’t generally use any kind of DevOps tools, but the maintenance of code requires some additional control. Developers often use GIT, TFS, GitLab, or Subversion to build a stable version of the application code.
2. Continuous Integration
These are frequent changes to the code that may happen every week or even every day, depending on the tasks involved. This phase is considered the main one in the DevOps lifecycle, with new code integrations constantly being written into the existing code. The most used tool here is Jenkins. With continuous deployment, it is known as CI/CD, the most known DevOps practice.
3. Continuous Testing
4. Continuous Feedback
Here the team analyzes improvements made during the integration and testing phases. The customers share their thoughts about the software, and developers evaluate changes in the final product.
5. Continuous Monitoring
The monitoring phase is the key to proper application development. Here, developers continuously monitor every functionality to ensure they are working properly. That helps to determine threats and root system errors, as well as resolve most security issues. Monitoring tools in DevOps include Nagios, NewRelic, Sensu and Splunk.
6. Continuous Deployment
Continuous deployment is always active during the DevOps lifecycle, even after you launch an application for everyone to use and start receiving traffic. Here, you release the code to the production server/s and keep updating during the entire production process. The top DevOps tools here are Ansible, Puppet, and Chef, with Vagrant and Docker for containers.
7. Continuous Operations
CO is the last and the shortest phase of the lifecycle. Here, you automate the release and update processes.
Now, we’re going to tell you more aboutDevOps technologies used during these phases.
DevOps Automation Tools
GitHub is a source code management tool and the most popular in the 2021 DevOps lifecycle. It is expected to become an innovation leader.
The core functionality of Gitlabprovides an excellent GIT repository management tool. Its web interface is detailed and easy to use. Gitlab delivers everything you need with a free tier offering and comes in Software as a Solution (SaaS) and On-Prem form factors.
Jenkins is one of the most popular open-source automation tools for DevOpsto support continuous integration and delivery. This tool enables constant integration and project delivery, regardless of which platform users are working on, using different build and deployment pipelines. Developers can integrate Jenkins with several testing and deployment tools.
DevOps Deployment Tools
Puppet is one of the most popular DevOps deployment tools. It is an open-source configuration management tool to automate the verification, delivery and management of software throughout the development lifecycle. Thanks to this tool, the administrators don't need to create scripts to change the configuration manually.
Terraform solves the problem of defining your infrastructure as code, from network components to authentic server images. The latest version provides most of the same logic functions and classes in the HCL as any other traditional programming language, making it easy for developers to choose and learn. The ability to support any environment on-premises or in the cloud is unmatched. If you use AWS Amazon, use AWS deployment tools.
Container Software for DevOps
Kubernetes is an open-source container orchestration system initially developed by Google and currently supplied by the Cloud Native Computing Foundation. This tool automates the deployment, scaling and management of applications.
Docker is a tool for building, deploying and running applications using containers. This container allows a developer to package an application with all the required components and subcomponents and send it all as a single package.
It doesn't matter whether you choose Kubernetes or Docker Swarm as a tool for orchestrating the containers. The choice depends on the architecture and the results you try to achieve with the help of containerization applications or services. The separation of large applications and products running in containers can significantly improve development and reliability due to the limited range. But neither Kubernetes nor Docker Swarm can prevent you from using poorly designed services. It starts with your team.
Configuration Management Tools
Chef is a popular configuration management tool used to automate and simplify the deployment, recovery, upgrade and management of application infrastructures. Thanks to this tool, developers can avoid scripted manual changes. Chef also provides integrated, customizable policies that enable DevOps engineers to ensure continuous code releases. Chef is an open-source configuration management tool developed by Opscode using Ruby to manage infrastructure on virtual or physical machines. It also helps manage a complex infrastructure across virtual, physical and cloud machines.
Ansible is an open-source IT configuration management tool for software provisioning, configuration management, and application deployment. It is a simple yet powerful tool for automating complex and straightforward multi-tier IT applications. This configuration management tool and IT orchestration can connect to hundreds of other CI/CD tools. Thanks to this tool, the development process is fast and resilient for applications and services.
DevOps Monitoring Tools
The early releases of New Relicdid one thing really well -- APM monitoring. It is now a full-featured monitoring tool allowing you to monitor server performance, container performance, database performance, end-user monitoring, and of course, APM monitoring.
Nagios is one of the most used DevOps monitoring tools, and it is an open-source tool and one of the most popular continuous monitoring tools. Nagios helps track systems, applications, services and business processes in a DevOps culture. It alerts users when something is wrong with the infrastructure or when developers resolve the problem.
Testing Tools for DevOps
Cucumber combines specs and test documentation into a single, living document. Because Cucumber automatically tests them, your specifications are always up to date. If you want to complete a web automation testing framework and user behavior simulation in a web application, Selenium WebDriver with Java and Cucumber BDD is an excellent way to learn and implement Cucumber in your project.
Selenium is the most popular open-source testing tool. It supports test automation across different browsers and operating systems. It is easy to integrate with test management DevOps tools like ALM, Jira, and DevOps tools like Jenkins, Teamcity, Bamboo and others.
DevOps is an efficient way to develop an application or product. It increases efficiency and saves time by allowing users or customers to directly contribute to the product or application development process by exchanging continuous feedback.
DevOps is a promising area that continues to evolve. The versatility of DevOps specialists is highly valued, and ongoing active learning and adoption of new practices and approaches will keep you busy in the workplace.
