DevOps is a methodology that is the best combination of two processes:
Development and operations. DevOps tools are prominently used to improve the software development lifecycle.
In this blog, we shall discuss the benefits of DevOps, DevOps methodologies, and the key component of DevOps.
What is DevOps? and what benefits of DevOps
DevOps combines cultural philosophies, practices, and tools that improve an organization’s capacity to deliver applications and services at high velocity. Businesses use conventional software development and infrastructure management processes to improve product delivery. Due to this speed, organizations can provide better customer service and more competitive competition in the market.
The DevOps methodology promotes improved, continuous communication, cooperation, integration, visibility, and transparency between IT operations teams Ops)( and their application development (Dev) counterparts.
Every stage of the DevOps lifecycle—from early software planning to code, building, testing, releasing, and on to deployment, operations, and continuing monitoring—is characterized by this closer link between “Dev” and “Ops.”
This connection creates an ongoing feedback loop with customers, leading to creation, testing, and deployment, which are all improved upon. The more expeditious, continuous deployment of required feature changes or additions may be one outcome of these efforts.
Some development groups classify DevOps into four: culture, automation, measurement, and sharing (CAMS), and DevOps tools are sufficient in these areas. These technologies can improve the efficiency and collaboration of development and operations workflows by automating rather than manual or static procedures involved in integrating, developing, testing, deploying, or monitoring.

Why DevOps matters
A primary benefit of DevOps in the development process is that it provides customer satisfaction and quick product delivery. Moreover, it helps communicate with the team more efficiently without any obstacles and helps create an efficient interaction between the IT operation and the development team. Additionally, DevOps is intended to support company innovation and the pursuit of ongoing process improvement.
The DevOps methodology promotes delivering corporate value to clients more quickly, better, and securely. The value might be represented by more frequent product updates, deployments, or enhancements.
Software efficiency, scalability, and stability are all supported by the underlying infrastructure as it is initially designed, tested, and then put into production.
Now, we shall discuss a few DevOps tools for testing.

DevOps methods
Organizations can utilize a few popular DevOps techniques to accelerate and enhance product delivery. They come in the form of software development methodologies and practices. Scrum, Kanban, and Agile are among the most popular ones:
Scrum: Scrum explains how team members should collaborate to expedite development and quality assurance tasks.
Scrum practices contain critical processes and unique terminologies like sprints, time boxes, daily scrum, and roles like Scrum Master and product owner.
Kanban: Kanban was created in response to increased efficiency realized on the Toyota factory floor. Kanban suggests using a Kanban board to track the progress of software project work-in-progress (WIP).
Agile: DevOps approaches and tools are significantly influenced by earlier agile software development methodologies.
Scrum and Kanban are only two examples of DevOps techniques used by agile development. Some agile methods include daily standups, work records as user requirements, integrating continuous customer feedback, and being more flexible to changing needs and requirements. Agile promotes a faster software development lifecycle than the drawn-out, conventional “waterfall” development processes.
DevOps toolchain
As part of their DevOps “toolchain,” developers often employ some DevOps-friendly solutions. These technologies are intended to speed up, streamline, and automate additional software delivery pipeline phases.
Many of these technologies also support the fundamental DevOps principles of automation, teamwork, and interaction between operations and development teams.
Below is a list of the tools used at various stages of the DevOps lifecycle.
- Plan: In this phase of the development process, the developer will plan to meet the requirement of the business. Moreover, they utilize the tools such as Jira, GitHub, GitLab, TaraVault, Jenkins, CircleCI, etc., for project management.
- Code: In this phase, the software developer will plan how to write code. Software developers might use Stash, GitLab, GitHub, and Bitbucket to write efficient code.
- Build: In this development phase, the software developer will manage the software, and with the aid of automation tools, you will be able to compile and pack code for future product releases.
- Test: The software tester involves automated and manual testing in this development phase. The purpose of testing the code or process is to ensure code quality. Examples of automation testing tools are Kobiton, Jenkins Bamboo, JMeter, Selenium, Appium, SoapUI, etc.
- Deploy: For software deployment, software developer use tools for managing, coordinating, scheduling, and automating product releases into production. During this phase, the software developer utilizes tools like Puppet, Chef, Ansible, Jenkins, Kubernetes, OpenShift, OpenStack, Docker, and Jira.
- Operate: Production software is managed during this stage. Ansible, Puppet, PowerShell, Chef, Salt, or Otter are a few examples of tools.
- Monitor: This stage comprises identifying and gathering data based on the problems with a software release currently in use. New Relic, Datadog, Grafana, Wireshark, Splunk, Nagios, and Slack are a few examples of tools.

DevOps practices and DevOps methodologies:
DevOps practices reflect the idea of continuous improvement and automation. Many techniques focus on one or more development cycle phases. These practices include:
- Continuous development. This method covers the planning and coding aspects of the DevOps lifecycle. Version-control techniques are used.
- Continuous testing: This technique employs automated, organized, continuing code testing when application code is generated or modified. These tests can accelerate the release of code to the production environment.
- Continuous integration (CI): This approach combines configuration management (CM) technologies with additional testing and development tools to monitor the proportion of production-ready developing code. So, testing and development must deliver prompt feedback to enable the rapid identification and rectification of code errors.
- Continuous delivery: This procedure automates the distribution of code modifications to a preproduction or staging environment following testing. Then, a staff member can choose to promote such code alterations into production.
- Continuous deployment (CD). Like continuous deployment, this approach automates the release of new or changed code into production. Continuous deployment allows businesses to release code or feature updates multiple times daily. Continuous deployment can be made possible by container technologies like Docker and Kubernetes, which help preserve code consistency across several deployment platforms and environments.
- Continuous monitoring: This procedure entails continuous observation of both the running code and the underpinning infrastructure. A feedback loop reports bugs or problems and then circles back to the development process.
- Infrastructure as code: During various DevOps phases, this technique can be utilized to deliver the infrastructure required for a software release automatically.
- Developers use the resources to add “code” to infrastructure.
- Developers might, for example, use OpenShift, Kubernetes, or Docker to create a storage volume on demand.
- Additionally, by using this process, operations teams may monitor environment setups, trace changes, and speed up configuration rollback.

Why DevOps?
Before moving on, it’s crucial to comprehend why DevOps is preferable to other approaches.
- The operation and development team will work independently.
- Following design-build, testing and deployment are carried out in turn.
- They took longer to complete than actual construction cycles because of this.
- Without DevOps, the team members would spend more time testing, creating, and deploying than working on the project.
- In production, manual code deployment increases the risk of human mistakes.
- The coding and operating teams’ distinct schedules and lack of coordination add to the delays.
Benefits of DevOps
Many of the advantages listed by DevOps supporters, both technical and business-related, can make consumers happier. Among DevOps’ benefits are:
- In software development, DevOps integrate the software development process faster and better.
- With this, we can solve the problem quickly and reduce the complexity of the development process.
- Provide flexibility, scalability, and availability of the feature.
- Provide stability in the operating environment.
- Support for automation testing
- Better use of resources
- Increased transparency of system results
- Greater inventiveness
- Applications must be integrated with the rest of the environment’s elements. The old code is integrated with new functionality during the integration phase, after which it is tested. Continuous development is made possible through continuous integration and testing.
- There are major operational issues as a result of the frequency of releases and micro-services. Continuous integration and delivery are used to deliver in a speedier, safer, and more dependable way in order to address such issues.
