[edit] Trends in DevOps

The DevOps trend is a movement of IT leaders who want to see things change for the better—to provide software to their clients consistently and with confidence. The global DevOps market size was valued at $ 6.78 billion in 2020 and is projected to reach $57.90 billion by 2030, registering a CAGR of 24.2% from 2021 to 2030.

As compared to conventional methods, enterprise DevOps brings development and operations together, enhancing the efficiency, timeliness, and safety of software development and execution. A more agile SDLC (software development lifecycle) can give enterprises a competitive advantage.

Agile software development, IT service management frameworks, project management guidelines such as Lean and Six Sigma, and other methodologies can all coexist with DevOps. All teams can respond to customer feedback and requests and maximise productivity.

[edit] What is DevOps?

Patrick Debois created the term “DevOps” in 2009. DevOps is a word that combines the terms “development” and “operations” to denote a collaborative or shared approach to a company’s software development and IT operations teams’ activities. A DevOps deployment methodology stems from an Agile approach to software development. It builds on the cross-functional approach to building and deploying applications in a shorter and more iterative manner.

In simple terms, DevOps is a software engineering approach that tries to connect the work of software development and software operations teams by fostering a culture of collaboration and shared accountability. DevOps is a combination of concepts, techniques, and tools that assist an organisation to create better products faster by allowing the development and operations groups to work together more effectively.

[edit] History of DevOps

In 2007, Patrick Debois, a project manager with the Belgian government, was assisting with data centre transfers. The barrier between the developers and the operations team made the entire process exceedingly difficult for him by making the delivery considerably slower. Debois was a firm believer in the agile methodology, which encourages continuous testing throughout the development lifecycle, allowing developers to deliver better products more quickly. Similar concepts, he argued, should apply to development and operations departments operating in tandem.

The following are the two key precursors of DevOps:

• Enterprise systems management (ESM): Many of the folks that helped define DevOps, in the beginning, were system administrators. System monitoring, configuration management, automated provisioning, and the toolchain approach were all brought to DevOps by these operation specialists.
• Agile development: DevOps can be regarded as an offshoot of agile software development that prescribes strong collaboration of consumers, product management, developers, and (occasionally) QA to fill in the gaps and quickly iterate towards a better product.

DevOps also recognises that delivery of services and how the application and systems communicate are critical components of the client’s value proposition and that those concerns must be addressed as a top-level item by the product team. From this perspective, DevOps is essentially stretching Agile methodology beyond the confines of code to the fully-delivered service.

[edit] How does DevOps work?

In older contexts, development and operations usually work in different teams within a company. The development team would write the code, while the operations team would put it in place and manage the IT infrastructure.

When a problem arises, they begin to blame each other rather than find a solution. This disconnect between these two divisions is extremely harmful and causes a slew of issues for software development firms.

The DevOps methodology helps improve the situation and smooth out the software development process. DevOps in the enterprise also attempts to solve almost all existing difficulties and tear down the barriers between development and operations. This method allows the entire team to quickly develop T-shaped competencies and more actively adapt to market developments.

[edit] Traditional SDLC challenges

The traditional SDLC (Software Development Lifecycle) approach has various significant flaws that must be addressed in order to improve software development efficiency.

That is why DevOps services is important to be adopted by enterprises. All of the major challenges and issues listed below have been eliminated with DevOps, resulting in increased productivity and faster software delivery.

[edit] Management bottlenecks and siloed structures

The traditional SDLC method separated the software developers, test engineers, & maintenance departments into three distinct divisions, each of them performing the operational functions sequentially and without interaction.

A communication gap, along with a siloed departmental structure, results in a dis-organised and time-consuming approach, as well as a defective product.

[edit] Lack of transparency and late feedback

Because of the several work stages, the consumer is engaged with the products later. This leads to inconsistencies between what was intended and what was delivered, needing rework. Employees are also compelled to work longer hours due to a lack of coordination and integration and often refuse to adapt to user complaints promptly.

[edit] Updates and late fixes

When there is no direct connection or responsibility between the test engineers and developers, fixing a bug, making new adjustments, and releasing them can take several months. An organisation cannot expand and compete in the industry if it consistently fails to execute and deliver projects on schedule.

[edit] Inadequate testing and a high risk of errors

In traditional SDLC, tests are done independently in-unit formats. Due to departmental silos, test specialists struggle in maintaining a continuous process at all levels of development. As a result of these issues, the teams face a slew of problems, including post-release problems that could be avoided if there is more frequent communication.
