What is DevOps? 2024 Best Guide To Tools, certifications, Benefits, and more

In the time of technological domination and continuous development, organizations, regardless of their domain, are trying to keep up with this ongoing evolve to ensure constant competitiveness in their fields. With these changes becoming the heart of businesses, there’s no doubt that DevOps is at the core, proving itself vital for the success of future engineers.

What is DevOps?

According to PeopleCert DevOps means a software development approach to work that combines software development (Dev) with information technology operations (Ops). The goal of DevOps is to shorten the systems development life cycle while delivering software releases frequently, in close alignment with business objectives in a faster, better, and cost-efficient way. The DevOps approach to work is based on three critical success factors: cultural shift, improvement of practices and processes, and leverage of automation technologies.

DevOps can be defined as a collaboration between development and operations teams. It is a process or practice that helps in continuous integration and union which can better collaboration and delivery of value to the end users.

The term DevOps is formed by combining the two words "Development" and "Operations" which signifies a new and solid integration between operation and development teams and fills the gap between them.

By using DevOps, organizations can accelerate the delivery of services as well as enhance quality. In this regard, Development and operation agents work together on projects from the scratch, i.e. from the design and development process to product releases and support. By this, consequently, they can control, manage and minimize the risks by getting continuously updated feedback from the end-users and stakeholders at early stages.

What are the benefits of DevOps?

The benefits of adopting DevOps methodology:

• Staying ahead in the market by following the latest updates.
• Accelerating product delivery.
• Reducing failure rate of new releases.
• Minimizing risks by getting continuous feedback.
• Offering a more stable operating environment.

What are the DevOps Tools?

Organizations that follow DevOps use various tools that can enhance the workflow of each stage in the delivery process. The following presents a sample of tools used at DevOps lifecycle stages:

• Plan:

Tools like Jira or Git can be used to help manage, plan and track the work in this stage.

• Code:

Tools like GitHub, GitLab, Bitbucket, or Stash can be used in this stage.

• Build:

Tools like Docker, Ansible, Puppet, Chef, Gradle, Maven, or JFrog Artifactory can be used in this stage.

• Test:

Tools like JUnit, Codeception, Selenium, Vagrant, TestNG, or BlazeMeter can be used to help in continuous testing in this stage.

• Deploy:

Tools like Puppet, Chef, Ansible, Jenkins, Kubernetes, OpenShift, OpenStack, Docker, or Jira can be used in this stage.

• Operate:

Tools like Ansible, Puppet, PowerShell, Chef, Salt, or Otter can be used to manage software during production in this stage.

• Monitor:

Tools like New Relic, Datadog, Grafana, Wireshark, Splunk, Nagios, or Slack can be used to collect information in this stage.

DevOps Certifications

The need for skilled DevOps professionals is growing fast, because of the increasing global demand for rapid developmental strategies and continuous application deployments.

DevOps is known for combining more than one field, so it is a practice that combines tools and technologies from each field together. In this regard, there is no specific one certification that covers all fields. Based on the market needs, many certifications prove their significance for DevOps practitioners.

What is the Difference Between DevOps and Agile?

DevOps with Agile since are both considered software development methodologies and have many similarities. Despite all these similarities, they are not alike.

 To reduce the confusion, we will elaborate on the differences between DevOps and Agile as follows:

• Agile helps to manage complex projects while DevOps's central concept is to manage end-to-end delivery processes.
• The agile process focuses on constant changes whereas DevOps focuses on constant testing and delivery.
• Agile Feedback is given by the customer while DevOps Feedback comes from the internal team.
• Agile addresses gaps in Customer and Developer communications whereas DevOps addresses gaps in Developer and IT Operations communications.
• Agile requires a small team while DevOps requires relatively a large team.
• The target area of Agile is Software development whereas the Target area of DevOps is to give end-to-end business solutions and fast delivery.
• JIRA, Bugzilla, and Kanboard are some popular Agile tools whereas Puppet, Chef, TeamCity OpenStack, and AWS are popular DevOps tools.
• Developing software is inherent to Agile while developing, testing, and implementing all are equally important to DevOps.
• Agile addresses the gap between customer needs and development and testing teams while DevOps addresses the gap between development and testing and operational teams.

Organizations and businesses should know and understand both Agile and DevOps methodologies in order to be aware of how they help teams to work more efficiently, achieve fast delivery and increase customer satisfaction.
