DevOps Fundamentals

Author : admin

The assembly-line approach provides a level of repeatability and quantifiable verification for mass-produced products. Factories adopt the progressive assembly approach to minimize waste, maximize efficiency, and deliver products of higher quality. In recent years, software engineering organizations have begun to gravitate towards this progressive assembly-line practice to also help reduce waste, improve throughput, and release products of higher quality. You will learn how software development is more like craftwork than factory work and that working in silos leads to mistakes and bottlenecks. You will see how DevOps is driven by behaviors such as collaboration and embracing change. You will be introduced to concepts such as ephemeral infrastructure that emphasizes building quickly and then discarding when that build is no longer needed.

devops fundamentals

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. One of the essential parts of a successful DevOps workflow is making sure itโ€™s โ€œcontinuous,โ€ or always on. This means setting up a process to ensure the workflow takes on a continuous recurring frequencyโ€”or, more simply, making sure youโ€™re putting your DevOps workflow into practice. To succeed, DevOps https://remotemode.net/ requires a close-knit working relationship between operations and developmentโ€”two teams that historically were siloed from one another. The basic concept of modularity is to avoid creating a monolithic implementation of a software system. In this section, we will outline some of the more popular architectures and practices to evolve from the DevOps movement and learn how they are being leveraged to provide flexibility and velocity at organizations worldwide.

Continuous Integration and Continuous Delivery

In 2001, the agile manifesto was officially published, and organizations soon began breaking work into smaller chunks and getting orders standing up instead of sitting down. Functionality was prioritized, and work items were divided across team members for completion. This meant that the team now had rigid timelines and 2- to 4-week deliverable deadlines. Anyone who wants to learn DevOps can benefit from it, but it is especially beneficial for those who work in software development or IT. The course then carries on to Introduction to Operations, since, once you’ve got your deployment up and running, you then need to know how to keep the operations running smoothly. That then leads to the final hands-on lab in the series, in which you’ll learn how to monitor your operations in AWS by building a log aggregation system.

  • The idea of continuously merging contributions meant that organizations would no longer need an integration phase, and QA could begin to take place as the software was developed.
  • During this conference, Patrick spoke of a highly collaborative development team he worked with during his tenure at a large enterprise.
  • As a result of these innovations, a new demand for automation engineers, configuration-management personnel, and DevOps-oriented engineers has cropped up.
  • Gone are the days of manual environment provisioning, a priesthood of release engineering, and late-night stale-pizza release parties.

DASA emphasizes six key principles crucial for effective adoption and transition to a DevOps-centric approach, underscoring the importance of experiences, ideas, and cultural shifts in becoming a high-performance digital organization. While the practice of CI may sound quite easy, in many ways, it’s quite difficult for development organizations to implement. The idea of an elastic implementation of computing resources, which could scale at ease with organizations that were expanding rapidly provided a wave for the innovation of the future. By 2012 Cloud computing was a huge trend and hundreds if not thousands of companies were clamoring to get to the cloud. Measuring successes and failures provides critical business data and helps pave the way for higher efficiency through effective change. This simply emphasizes that business decisions can be made through data and metrics rather than gut reactions.

DevOps is a software development and IT operations process that helps to improve the collaboration between developers and operators by automating the Deployment, configuration, monitoring, and management of applications. By contrast, DevOps methodology fundamentally seeks to bring large, historically siloed teams (developers and operations) together to enable faster software development and release cadences. Continuous monitoring is a set of automated processes and tooling used to troubleshoot issues and development teams can use to inform future development cycles, fix bugs, and patch issues.

They would progress in their development efforts in relative isolation until everyone was done and a subsequent integration phase of development took place. This inherently created a significant amount of risk, which could result in the insolvency of the business. With software engineering risks at an all-time high and businesses averse to Vegas-style gambling, something needed to be done. DevOps is a methodology that promotes collaboration between development and operations teams, aiming to streamline software development, delivery, and deployment processes. Everyone from operations and IT to engineering, product management, user experience, and design plays a role in a successful DevOps environment.

With traditional IT organization being isolated from development, silos are a commonplace within organizations worldwide. In an effort to pave the way for rapid development and delivery, devops fundamentals a fundamental change in organizational culture must take place. This would be done in an effort to promote collaboration, sharing, and a sense of synergy within the organization.

  • The basic concept of modularity is to avoid creating a monolithic implementation of a software system.
  • Once the software system was handed from development to quality assurance, the development team would often remain hands off as the software eventually made its way to a release.
  • The module concludes with a deep dive into the best practices for implementing DevOps on GCP, along with real-world case studies to help you understand how these practices are put into action.
  • This course is suitable for those new to DevOps assuming basic IT literacy, and also those looking to increase their current knowledge of DevOps.
  • Inefficiencies such as integration phases, manual quality assurance, verification release plans, and execution often added a significant amount of time to the overall development and release strategies of the business.

The main addition that Continuous Delivery offers is that, once the validation of the code change is completed, the CD system will deploy (install) the software onto a mock environment and perform additional testing as a result. It is worth noting the source for CI mentioned here comes from Martin Folwer and James Shore. These software visionaries were instrumental in creating and advocating CI implementations and solid development practices. This is also the base platform required for Continuous Delivery, which was created by Jez Humble in 2012. From the DevOps movement, a set of software architectural patterns and practices have become increasingly popular.

We will delve into what it means to version your configuration states, how to go about developing code that maintains the infrastructure state, and what the ins and outs are for creating a successful configuration management (CM) solution. The artifact-management solution provides a single source of truth for all things deployable. In addition to that, it provides a way for the automation system to shrink-wrap a build or potential release candidate and ensure it doesn’t get tampered with after the initial build. In many ways, an artifact-management system is to binaries what source control is to source code. Monolithic software development implementations are most common in legacy code bases that were poorly designed or rushed through the development phase.

This course lays out the seven types of waste in complex systems, including how to prioritise and address bottlenecks in the software development cycle. We discuss the importance of measuring progress in a DevOps transformation and the software development cycle. To DevOps, you need to have a basic understanding of software development and operations. In the “Google Cloud DevOps Fundamentals” course, you will immerse yourself in the world of DevOps, starting from its principles and benefits to the hands-on application of these concepts in the Google Cloud Platform (GCP) environment.
