How To Explain Devops In Plain English


Infrastructure as code.This practice can be used during various DevOps phases to automate the provisioning of infrastructure required for a software release. Developers add infrastructure “code” from within their existing development tools. For example, developers might create a storage volume on demand from Docker, Kubernetes, or OpenShift. This practice also allows operations teams to monitor environment configurations, track changes, and simplify the rollback of configurations. In an Agile-only workflow, development and operations teams have separate objectives and leadership. When an organization uses DevOps and Agile together, both development and operations teams manage code throughout the software development lifecycle.

At the deployment stage, an engineer works with data processing, which requires experience with both SQL or NoSQL database models. These benefits come only with the understanding that DevOps isn’t merely a set of actions, but rather a philosophy that fosters cross-functional team communication. More importantly, it doesn’t require substantial technical changes as the main focus is put on altering the way people work.

At its core, DevOps relies on automating routine operational tasks and standardizing environments across an app’s lifecycle. Containers can offer standardized environments, but you need a platform to manage them that also offers built-in automations and support for any infrastructure. Red Hat OpenShift 4 is the enterprise-ready Kubernetes platform to support DevOps initiatives. In a DevOps environment, configuration management applies not only to the current solution being worked on but also on the configuration issues between the solution and the rest of the organisation infrastructure. Integrated Configuration management helps operations teams see the potential impact of a new release more clearly which helps in making better decisions regarding when the release should be made.

In other words, be more adaptive and data-driven for alignment with customer and business needs. Also, the practice of continuous Integration pushes changes to a central repository, and sets of automated tests validating that the entire app works correctly after the merge. If security and reliability is a concern, you can use the flexibility of source control to differentiate between the production-ready branch and the one that is on the bleeding edge.

In order to implement DevOps best practices described above, certain tools have been developed to automate and facilitate different DevOps processes. While the right tools play a key role in effective DevOps implementation, simply using the tools does not mean DevOps adoption. Tools are only relevant when they are used as the last stage- after the organisation has already adopted the philosophy of DevOps and there is a commitment to execute its best practices.

These principles challenged traditional waterfall development, which is rigidly sequential and exhaustively documented, and consists of sharply defined roles, tools and processes. But while agile development teams began to iterate software products more rapidly — responding nimbly to changing requirements and other circumstances — IT operations teams were not necessarily ready to move at this new pace. But NetApp doesn’t just make it easy for developers to consume storage as code. NetApp technology also allows operations to confidently provision and deliver resources to development and testing personnel.

what is devops and why devops

The same tools that monitor the production environment can be employed in development to spot performance problems before they hit production. By capturing and analyzing logs generated by applications, DevOps teams can better understand how software changes or updates may affect users. Software monitoring and logging.Once software is moved to production, it must be monitored to ensure stable performance and increased customer satisfaction.

Basic Quality Tools For Efficient Project Management

Operations, on the other hand, knows that rapid-fire changes without proper safeguards could destabilize the system, which goes directly against their charter. DevOps focuses more on operational and business readiness whereas Agile focuses on functional and non-function readiness. The two can be really closely related, in fact – so closely that it’s hard to tell the difference.

Create consumer-grade healthcare experiences and stay focused on patients through improvements to operational performance. Connect your telecom operations—from the network to the customer—on a single platform. Enable CSPs to enhance customer care and automate service assurance. Provide efficient, resilient financial services operations for enhanced customer and employee experiences. Streamline procurement for employees, boost productivity, and enable work team efficiencies across the enterprise.

Devops, For Ops

DevOps principles and practices lead to better communication between team members, and increased productivity and agility. Teams that practice DevOps are considered to be more productive and cross-skilled. Members of a DevOps team, both those who develop and those who operate, act in concert.

This continuous workflow approach enables teams to immediately identify and address issues related to both form and function earlier in the process to avoid problems before software is released into production. Ongoing feedback and open access to repositories encourages collaboration within and outside individual teams. It also promotes InnerSource, the process of using open source best practices to build internal code. Micro Focus helps its customers scale DevOps practices across traditional and hybrid IT environments. Enterprise DevOps can deliver in-novation by transforming and extending your current IT environments, with quality and security built in, every step of the way.

Chapter 1: What Is Devops?

Drive customer loyalty with connected digital workflows that automate work across departments. Deliver great experiences and enhance productivity with powerful digital workflows across all areas of devops organizational structure your business. Modernize with RPA and integrate modern tools enterprise-wide to increase output and business results. Empower citizen developers with low-code tools for building apps at scale.

  • In general, automation is a key element of DevOps and just as there is a cloud-first bias, there is an “automate it” bias.
  • This process of maintaining the code is known as Source Code Management.
  • Empower citizen developers with low-code tools for building apps at scale.
  • AWS is the best example of it, their pay-as-you-go model and billing on per second basis has motivated developers to optimize their code to the nth degree.
  • In contrast to traditional approaches of project management, Agile planning organizes work in short iterations (e.g. sprints) to increase the number of releases.
  • In a DevOps environment, configuration management applies not only to the current solution being worked on but also on the configuration issues between the solution and the rest of the organisation infrastructure.
  • Today most organizations use hybrid clouds, a combination of public and private ones.

The DevOps approach goes hand-in-hand with Linux® containers, which give your team the underlying technology needed for a cloud-native development style. Containers support a unified environment for development, delivery, integration, and automation. That’s why DevOps teams will often build their software using a microservices architecture and link these services together with APIs. Teams deliver faster by focusing on creating smaller pieces of functionality so you’ll have to focus on how those services and APIs are managed and have a strategy, like agile integration, for bringing it all together.

How Can Your Team Benefit From Devops?

We often talk about the benefits DevOps brings to the developer and operations teams directly, but the benefits of DevOps also extend to the scope of the entire business right up to the C-level. And Patrick Debois, known as the creator of the DevOps movement, notes the greatest advantage of DevOps is the understanding it gives. More frequent releases mean users can access new features and functions more quickly. They also mean developers get real-world feedback more quickly, which means they can respond to issues and make optimizations more rapidly. There is no shortage of DevOps tools IT teams can use today to execute different parts of the DevOps lifecycle.

Monitoring and alerting are configurable by the team operating the service. In 2008, Patrick Debois of Belgium and American Andrew Clay Shafer began discussing the challenges of bringing “agility” to IT infrastructure. A year later, Debois held the first “devopsdays” event in Ghent, Belgium. Bring data to every question, decision and action across your organization. Over the coming years, industry and open-source tools and frameworks were developed and proposed to further the goals of DevOps. Kanban.Kanban originated from efficiencies gained on the Toyota factory floor.

The regulatory environment for large organizations is why they have strong controls in IT operations for releasing application updates. These controls are ripe for automation, as they have been based on manual processes. DevOps offers a large competitive advantage via automated code functions that occur throughout the software development lifecycle.

The DevOps Engineer is a vital member of both teams and communicates. Even though DevOps Engineer often has to work alone, they are very good at working with others. This is because their job requires them to build on the work of their colleagues in the development and IT teams to scale cloud programs, make workflow processes, and assign tenants.

However, automation only happens if the teams know that automation capabilities are available, and that many previously manual functions are increasingly automated, such as ITIL change management. Automation can significantly improve the developer experience by freeing developers from administrative tasks. Systems administrators wanted to keep up with more efficient Agile product development teams, which were creating production-quality software more frequently. Teams were getting better at delivering software, but bottlenecks remained in the rest of the value stream, in areas like up-front planning and the deployment and management of systems in production. Back then—and even now for many organizations—these bottlenecks caused friction between development and operations teams.

Getting To Know Devops And Sre

The result is better, higher-performing, and more secure software — with less work needed by human beings. In short, automation reduces toil, helps you accelerate your delivery pipelines across the full SDLC, and enables you to scale your DevOps practice. CI is tightly controlled; new commits trigger the creation of fresh test builds via the build management system. Redundant code is rejected, and breaking changes are minimized once master branches are altered. Additionally, reduced reconciliation prevents mandatory code freezes that commonly stem from conflicts.

Consider modernizing existing workloads by leveraging DevOps principles and automation. Legacy workloads can derive significant benefits in terms of release cadence, reliability, and stability. Start with a real application, a dedicated team and tackle something small that still demonstrates business value. Build up to more complex, business-critical applications as you learn how to apply DevOps.

In 2003, Google developed site reliability engineering , an approach for releasing new features continuously into large-scale high-availability systems while maintaining high-quality end-user experience. While SRE predates the development of DevOps, they are generally viewed as being related to each other. They are in weight training and cardio programs during the week to keep them physically ready for the grueling conditions of race day. They continually collaborate to address any issue that might come up. If the safety systems are in place and practice runs have been going well, release to production happens more frequently. DevSecOps integrates security practices into the DevOps process, making everyone accountable for security, rather than merely passing code to a separate security team at the end of the process.

DevOps is an approach that focuses on integration and collaboration between development and IT teams to shorten the development and deployment cycle of products. Cloud-native is an approach to building applications that leverage foundational cloud computing technologies. The goal of cloud-native is to enable a consistent and optimal application development, deployment, management and performance across public, private and multicloud environments.

AI for DevOps means smarter automation and even shorter wait times, even seamless translations from business need to technological offering — but plenty of barriers remain before this becomes reality. From automated code preparation to a CI/CD pipeline, orchestration, monitoring and feedback — here’s how every piece contributes to a successful DevOps methodology. Because of the continuous nature of DevOps, practitioners use the infinity loop to show how the phases of the DevOps lifecycle relate to each other. Despite appearing to flow sequentially, the loop symbolizes the need for constant collaboration and iterative improvement throughout the entire lifecycle. DevOps is how engineering organizations collaborate using cross-functional teams.

Operated using Kubernetes, an open-source container orchestration platform for scheduling and automating the deployment, management and scaling of containerized applications. Bymanaging engineering processes end to end, DevOps emphasizes deploying software more often, in a reliable and secure way through automation. Furthermore, pick one image, like an Ubuntu image for Vagrant or Alpine base image for Docker and stick to it. Nothing wastes more time than disparity between different environments. When the base image is updated, make sure it is updated throughout all the environments.

DevSecOps aims to deliver secure software faster, with fewer late-stage defects and less rework. The early 2000s saw the need to maintain availability of popular websites such as Google and Flickr against massive hits. This need led to the use of software reliability engineers —operations people working closely with developers to ensure that the sites would keep running after code was released into production. Speed application development, improve software quality, reduce business risk, and shrink costs.
