DevOps is a set of practices, tools, and a cultural philosophy that automate and integrate the processes between software development and IT teams. It emphasizes team empowerment, cross-team communication and collaboration, and technology automation.

The DevOps movement began around 2007 when the software development and IT operations communities raised concerns about the traditional software development model, where developers who wrote code worked apart from operations who deployed and supported the code. The term DevOps, a combination of the words development and operations, reflects the process of integrating these disciplines into one, continuous process.

Benefits of DevOps

In Atlassian’s 2020 DevOps Trends survey, 99 percent of respondents said that DevOps had a positive impact on their organization. The benefits of DevOps include faster and easier releases, team efficiency, increased security, higher quality products, and consequently happier teams and customers.

Speed

Teams that practice DevOps release deliverables more frequently, with higher quality and stability. In fact, the DORA 2019 State of DevOps report found that elite teams deploy 208 times more frequently and 106 times faster than low-performing teams. Continuous delivery allows teams to build, test, and deliver software with automated tools.

Improved collaboration

The foundation of DevOps is a culture of collaboration between developers and operations teams, who share responsibilities and combine work. This makes teams more efficient and saves time related to work handoffs and creating code that is designed for the environment where it runs.

Rapid deployment

By increasing the frequency and velocity of releases, DevOps teams improve products rapidly. A competitive advantage can be gained by quickly releasing new features and repairing bugs.

Quality and reliability

Practices like continuous integration and continuous delivery ensure changes are functional and safe, which improves the quality of a software product. Monitoring helps teams keep informed of performance in real-time.

Security

By integrating security into a continuous integration, continuous delivery, and continuous deployment pipeline, DevSecOps is an active, integrated part of the development process. Security is built into the product by integrating active security audits and security testing into agile development and DevOps workflows.

Evolution of DevOps

Originally coined by Patrick Debois, DevOps has become a critical discipline for realizing the benefits of Agile that  ensures that rapid, iterative code development results in rapd, iterative code deployment!  While Agile’s gained popularity, often at cross-purposes with the more formal and “heavy” ITIL methods popular with IT in the early and mid-2000s, DevOps resonated with both sides. Organizations that have adopted ITIL can also implement DevOps, especially for Cloud-based applications.

Starting with The Phoenix Project, by Gene Kim, DevOps has steadily gained popularity and supporters, and is seen today as a crucial element of any Agile technology organization. Consequently, large corporations and all sorts of technology vendors now support DevOps. DevOps jobs have become ever more popular – and the norm – in hitech organizations.

With the emergence of AI and ML in all aspects of the software lifecycle, AI for DevOps is starting to make DevOps even more smart, fast and seamless – tho’ a lot remains to be done.

DevOps Automation Tools

It is vital to automate all the testing processes and configure them to achieve speed and agility. This process is known as DevOps automation.

The difficulty faced in large DevOps Team that maintain large huge IT infrastructure can be classified briefly into six different categories.

Infrastructure Automation

Configuration Management

Deployment Automation

Performance Management

Log Management

Monitoring.

Summary

DevOps is a mission-critical organizational function and capability that is needed as a number of these organizations undertake their Digital Transformation and Agile Transformation initiatives.  This article summarizes the key aspects of DevOps and provides an overview of what you need in order to get going with your own DevOps initiative – or take your current DevOps initiative to the next level. The sooner your engineering and IT organizations master DevOps, the more effectively your Business Agility goals will be met.

  Robotic Process Automation Robotic process automation (RPA) is a software technology that makes it easy to build, deploy, and manage software robots that emulate humans actions interacting with digital systems and software. Just like people, software robots can do things like understanding what’s on a screen, complete the right keystrokes, navigate systems, identify and extract data, and perform a wide range of defined actions. But software robots can do it faster and more consistently than people, without the need to get up and stretch or take a coffee break. Benefits of RPA There are multiple benefits of RPA, including: 1. Less coding 2. Rapid cost savings 3. Higher customer satisfaction 4. Improved employee morale 5. Better accuracy and compliance 6. Existing systems remain in place Why is RPA the fastest-growing enterprise software in the world? When you combine RPA’s quantifiable value with its ease of implementation relative to other enterprise technology, it’s easy to see why

  Cloud computing is the delivery of different services through the Internet. These resources include tools and applications like data storage, servers, databases, networking, and software.Rather than keeping files on a proprietary hard drive or local storage device, cloud-based storage makes it possible to save them to a remote database. As long as an electronic device has access to the web, it has access to the data and the software programs to run it.Cloud computing is a popular option for people and businesses for a number of reasons including cost savings, increased productivity, speed and efficiency, performance, and security. Types of Cloud Computing 1.Software-as-a-service (SaaS) 2.Infrastructure-as-a-service (IaaS) 3.Platform-as-a-service (PaaS)  Top Cloud Service Providers:   1.Amazon Web Services AWS is Amazon’s cloud web hosting platform which offers fast, flexible, reliable and cost-effective solutions.
