It ensures the application to interact with only those resources that are concerned with the environment in which it runs. The configuration files are not created where the external configuration to the application is separated from the source code. The configuration file can be written during deployment, or they can be loaded at the run time, depending on the environment in which it is running.

There’s no way to find that compromise without connecting a team’s preferred tools and practices to customer needs. Hopefully, this article sparks that initial conversation around orienting towards the customer. In this module, you will learn how business models are disrupted by innovation and that technology is the enabler devops fundamentals of innovation, rather than the driver of innovation. You will learn that DevOps is more than simply the Dev team and the Ops team working together. Through a brief history of DevOps, you will see how DevOps grew as a grassroots movement and that influential people helped others see that DevOps is a better way to work.


From headlines to job descriptions, DevOps has emerged as an outsized buzzword over the past decade-and for good reason. Organizations that successfully adopt DevOps often see big gains in software development speeds, improved reliability, faster product iterations, and have an easier time scaling their services. From headlines to job descriptions, DevOps has emerged as an outsized buzzword over the past decade—and for good reason. In this track, we will delve into the new tools and techniques in this space that make the cloud highly usable and functional for developers and applications. We will let the experts or “survivors” share their lessons learned to take continuously evolving distributed applications to the cloud while keeping the DevOps culture which holds it all together.

  • DevOps is a methodology and cultural approach that emphasizes collaboration and integration between development and operations teams to streamline software delivery processes.
  • Throughout this learning path, you’ll understand the key concepts of DevOps and how organizations use these principles to improve software development and IT operations.
  • The operations and development teams will then test that code to detect any security issues, bugs, or issues before deploying it to production.
  • This means setting up a process to ensure the workflow takes on a continuous recurring frequency—or, more simply, making sure you’re putting your DevOps workflow into practice.

You will examine how creating shared repositories and pair programming results in defects found earlier and a broader understanding of the code base for the team. You will see how working in small batches reduces waste and results in delivering useful applications quickly. You will discover how producing a minimum viable product allows you to test a hypothesis and gain valuable feedback about delivering what the customer really desires.

Security in DevOps

In doing so, those organizations prioritize building DevOps environments that are collaborative with an all-in approach that extends across teams and focuses on an end-to-end product instead of siloed, incremental projects. DevOps offers several benefits, including faster software delivery, improved collaboration and communication, enhanced quality and reliability, increased efficiency and productivity, and better customer satisfaction. This presentation will cover the concepts and tooling for wrangling identity, access management, and secrets (passwords, ssl certificates, access tokens, etc.) in cloud services. In identity, we will cover methods of handling Single Sign On (SSO) for services and user management in services that don’t support SSO. With access control, we will cover methods of limiting access to services and infrastructure, methods of controlling access to secrets, including… If you’re looking to build your knowledge of DevOps tools other than Docker and Kubernetes, check out these learning paths.

The operations and development teams will then test that code to detect any security issues, bugs, or issues before deploying it to production. Every phase of the software development lifecycle, including planning, coding, testing, deployment, and monitoring, is heavily automated in DevOps. This improves productivity, ensures consistency, and lowers error rates in the development process. A culture of continuous improvement is also promoted by DevOps, where feedback loops are incorporated into the procedure to facilitate quicker iteration and better decision-making. Organizations can increase their agility, lower costs, and speed up innovation by adopting DevOps. Automation can reduce time consumption, especially during the testing and deployment phase.


At GitHub, we approach DevOps as a philosophy and set of practices that bring development, IT operations, and security teams together to build, test, iterate, and provide regular feedback throughout the SDLC. Linux is one of the most popular operating systems for servers and cloud-based infrastructures. It gives access to a robust CLI, a scripting environment, essential tools and utilities, strong security features, and powerful diagnostic tools for troubleshooting. In order to master the art of delivering high-quality software and infrastructure, it is required for a DevOps Engineer to master Linux. Do you want to learn about a framework that can help your organization overcome these challenges?

fundamentals of devops

It is a culture to promote the development and operation process collectively. Michael has 20+ years of experience in IT industry primarily in DevOps and Cloud. He has contributed to various large-scale companies like AWS, Redhat, Thoughtworks, and Honeywell.

Specification by example is a way to get more detailed about the work, without losing customer perspective. Examples describe how customers interact with a system, so that we can better test our design. Instead, collaborating on the creation of examples builds customer empathy across the team.

Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that’s something I have never had in other learning platforms. If this characterizes your situation, there’s likely a gap in the trust between your management and your team, and perhaps even between your team members. It’s a team culture problem where trust is scarce but blame is everywhere.
