🟢Introduction

DevOps is the union of

🔹People

🔹Process

🔹Product

to enable continuous delivery of value to end-users.

Ok. Let's look at DevOps via the lens of this definition. First, busting the myth:

🔸DevOps is neither a tool nor a technology. DevOps is we People follow a Process enabled by the Product to deliver value to end-users. The key here is the delivery of value to end-users.

🔸DevOps is a combination of the two words development and operations. It refers to a collaborative or shared approach to the duties performed by an organization's application development and operation teams.

🔸DevOps is a concept that, in its most extensive context, promotes improved communication and collaboration between these teams and other groups within a company. DevOps refers to the use of continuous software development, automation, and programmable infrastructure deployment and maintenance in its most specific way. The term also refers to cultural changes such as developing trust and unity between developers and system administrators and connecting technology projects with business requirements. The DevOps strategy is one of the many strategies employed by IT professionals to carry out IT projects that meet business objectives.

🟢How does DevOps work?

🔸The goal of the DevOps methodology is to enhance productivity throughout the whole software development lifecycle. A DevOps process can be seen as an infinite loop that includes the following steps: plan, code, build, test, release, deploy, operate, monitor, and — through feedback — plan, which resets the loop. DevOps means that an IT team creates software that fully satisfies user requirements, installs quickly, and performs well right away.

🔸To do this, organizations use a mix of culture and technology. Developers work on minor changes that go live independently of one another, and stakeholders and developers discuss the project to ensure that the product meets expectations. The software can be written quickly and easily, but making it operate is another matter.

🔸DevOps proponents employ containers or other techniques to ensure the program behaves consistently from development through testing and into production to release good code. They implement modifications one at a time so that issues may be tracked. For consistent hosting and deployment environments, teams rely on configuration management.

🔸Code modifications are frequently made in response to issues they find during live operations, frequently following a transparent post-mortem analysis and regular feedback loops. Developers may provide support for the running software, therefore it is their responsibility to address runtime issues. In the software design meetings, IT operations managers could be present and provide advice on how to use resources effectively and safely. These experts can promote a DevOps culture more effectively if they cooperate and share their abilities more.

🟢What problems do DevOps resolve?

🔸Although every organization has its difficulties, common issues include releases that take too long, subpar software, and IT that restricts business expansion. A DevOps project progresses more quickly from the specification to live software since there are no wait times, manual processes, or drawn-out reviews. Reduced cycle times can prevent requirements from changing, ensuring that the final product meets client expectations. Between IT specialities, DevOps resolves issues with prioritization and communication.

🔸Development teams must comprehend the production environment and test their code under realistic circumstances to provide workable software. The silos that a conventional organization creates for development and operations teams. This means that developers are happy when their code provides functionality; if the release has issues in production, the operations team is responsible for fixing them.

🔸When a problem emerges, developers in a DevOps culture don't just say, "It worked on my machine." The modifications introduced into production are minor and reversible. Additionally, the modifications are understood by everyone on the team, which makes incident management much simpler. Companies are better able to take advantage of market opportunities with a quicker path from idea to live software. DevOps gives organizations a competitive edge in this approach.

🟢Benefits of DevOps

DevOps is a culture that insists on communication, collaboration and integration between software development and IT operations team DevOps tools and processes enable faster delivery and give organizations a competitive advantage.

The DevOps approach makes development and operations work together seamlessly where some of the operations team’s responsibilities are shifted back to the development team. This is facilitated by applying DevOps tools and principles that automate the process and reduce the complexity of version control, configuration management, continuous integration, deployment, and continuous performance monitoring. This close alignment enables organizations to release new stuff in days rather than in months.
