The IT Revolutions were caused due to the Emergence of DevOps Environments
Introduction:
DevOps is a term representing the concurrence of development and operation. It is a new cultural shift more than tools and practices, where new ways of working are getting adopted. It is currently being defined as “A methodology, or a technique, or a process but in-fact it is a mindset that has evolved in response to the lack of collaboration efforts between the development and operation teams”.
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). it aims to shorten the systems development life cycle and provides continuous delivery with high software quality.
Ever since its ideation, everyone has recognized that DevOps has some unique potential. Through continuous innovation and development, DevOps has emerged to become a significant influence in the domain of software development and deployment.
Borne of the need to improve IT Service Agility, the DevOps movement lays great emphasis upon collaboration, communication, and integration among IT operations and software developments. A typical definition of DevOps would be the culture, movement, or practice that emphasizes the collaboration and communication of both software developers and other information technology professionals while automating the process of software delivery and infrastructure changes.

Origin of DevOps
The origins of the DevOps movement is commonly placed around 2009, as the convergence of numerous adjacent and mutually reinforcing movements: the Velocity Conference movement, especially the seminal “10 Deploys A Day” presentation given by John Allspaw and Paul Hammond the “infrastructure as code” movement (Mark Burgess and Luke Kanies), the “Agile infrastructure” movement (Andrew Shafer) and the Agile system administration movement (Patrick DeBois) the Lean Startup movement by Eric Ries the continuous integration and release movement by Jez Humble the widespread availability of cloud and PaaS (platform as a service) technologies (e.g., Amazon Web Services).
Principles of DevOps
In the DevOps Cookbook and When IT Fails: A Business Novel, we describe the underpinning principles from which all the DevOps patterns can be derived as “The Three Ways.” They describe the values and philosophies that frame the processes, procedures, practices, as well as prescriptive steps. The First Way emphasizes the performance of the entire system, as opposed to the performance of a specific silo of work or department — this can be as large a division (e.g., Development or IT Operations) or as small as an individual contributor (e.g., a developer, system administrator). The focus is on all business value streams that are enabled by IT. In other words, it begins when requirements are identified (e.g., by the business or IT), are built-in Development, and then transitioned into IT Operations, where the value is then delivered to the customer as a form of service. The outcomes of putting the First Way into practice include never passing a known defect to downstream work centers, never allowing local optimization to create global degradation, always seeking to increase flow, and always seeking to achieve a profound understanding of the system (as per Deming). The Second Way is about creating the right to left feedback loops. The goal of almost any process improvement initiative is to shorten and amplify feedback loops so necessary corrections can be continually made. The outcomes of the Second Way include understanding and responding to all customers, internal and external, shortening and amplifying all feedback loops, and embedding knowledge where we need it.
The Third Way is about creating a culture that fosters two things: continual experimentation, which requires taking risks and learning from success and failure; and understanding that repetition and practice is the prerequisite to mastery. We need both of these equally. Experimentation and risk-taking are what ensure that we keep pushing to improve, even if it means going deeper into the danger zone than we’ve ever gone. And we need mastery of the skills that can help us retreat out of the danger zone when we’ve gone too far. The outcomes of the Third Way include allocating time for the improvement of daily work, creating rituals that reward the team for taking risks and introducing faults into the system to increase resilience.
Benefits of DevOps
The benefits of DevOps outweigh the potential difficulties. Aligning the two transparency-limited siloed ensures that systems are delivered faster, and also reduces risks in production changes through nonfunctional and automated testing, as well as shorter developmental iterations. The DevOps approach automates the service management for the support of operational objectives and improves understanding of the layers in the production environment stack. In turn, this helps prevent and resolve production issues. Organizations may also realize that the differences are easier to overcome.
To make a DevOps approach successful, you need careful business management and a cultural change to go with the right skills. In short, companies incorporating DevOps practices are merely getting more things done. The code is deployed close to 30 times more frequently than that of competitors. The shift in attitude comes from the fact that there is a single team comprising cross-functional members, including QAs, developers, DBAs, operations engineers, business analysts, and the like. This collaboration offers immense benefits.
Technical Benefits:
- Problems are less complex and can be fixed a lot more easily
- Software delivery becomes a continuous process
- Problems are resolved more quickly
Business Benefits:
- Features are delivered more quickly
- Operating environments become more stable
- Additional time is available to add value (rather than fix/ maintain)
DevOps Mindset:
DevOps is more than just development and operation teams working together, more than tools and practices. DevOps is a mindset, a cultural shift, where teams adopt innovative ways of working. A DevOps culture means by understanding the user requirements and need by the developers, likewise developer get closer to the customers. Operations teams get involved in the development process and add maintenance requirements and customer needs. It means supporting to the key principles that help DevOps teams deliver applications and services at a faster pace and higher quality than organizations using the traditional software development model.
Need of DevOps mindset:
A software development team has to react promptly to any customer demand so achieving a faster time to market is a priority. Both the software development and Operations stake holders require to come to an agreement to achieve the objectives. This leads to the understanding of channel of communication between the Development and the Operations departments for joint collaborations.
The kind of continuous delivery that is requested from the Development and Operations departments require them to be agile achieving collaborations. To concur the customer offence and managing stress among teams we need to build a DevOps Mindset.
Also, with the overcome failures at various levels in an organization and over relying on cash cow products lead to a determined effort to change the conversation and introducing DevOps as a conversation to elevate and evolve the static processes.
Hence a dynamic model needs to adopt continuously to new market demands and creating an environment for the perfect integration of development, operations team efforts into the product life cycle
Opportunities in job:
DevOps is in high demand for the job roles in IT industry. It is becoming the future of the IT world as it is progressing at a very good rate. It helps business to collaborate the development and operation team task faster software delivery.
Pre-requisites:
- Bachelor’s degree in engineering
- Being proficient in at least one “popular” programming language
- Knowing the building blocks of public cloud provider
- Involvement in the community
- Skilled with several tools and technologies for DevOps implementations
Job roles in DevOps:
DevOps is fast growing and emerging field providing a new designations, roles, and responsibilities. The fascinating fact is, though companies list these roles separately, there is a lot of overlapping on the responsibilities, duties, and skill requirements. Following are the job profiles in DevOps Industry.
- DevOps engineer
- Security engineers
- Software testers
- DevOps architect
- Release manager
- DevOps evangelist.
- Integration specialist
Other measurable benefits include:
- A Shorter Development Cycle The DevOps approach promotes the culture of increased communication and collaboration between the operations and the development teams. This translates to shorter timeframes as they move from the engineering code onto the executable production code.
- Increased Release Velocity The shorter development cycle creates an increased frequency for the release code that turns into production. The usual timeframe is 3-6 months right from the requirements to the release. But with DevOps, it will be reduced to a daily or hourly release build cycle. This fosters a culture of continuous deployment and development and subsequently increases the value of IT to the business. The increased release velocity thus becomes a competitive advantage.
- Improved Defect Detection The DevOps approach is built on the Agile programming methodology and can be considered as extended Agile programming. It is prescribed to various principles of Agile like iterative development, collaboration, and modular programming, thus breaking the bigger codebases into smaller, much manageable features, making it easier to detect defects in the code.
- Reduced Deployment Failures and Rollbacks The benefits that are gained from faster deployment and development are usually invalidated by failed deployment. However, software developed with the DevOps approach takes into account the operational viewpoint as well. When combined with the improved defect detection clause, it can significantly reduce the number of issues before or after deployment, resulting in fewer rollbacks.
- Reduced Time to Recover, upon Failure Though the likelihood of failure is minimized, failure is inevitable. When it does occur, recovery time is relatively reduced with the use of DevOps, as compared to the traditional IT environment. This happens mainly due to the integration of teams.
Conclusion:
DevOps is a helping business; it is a bridging gap between developers and operations to create a smooth path for continuous development and continuous delivery. The future of DevOps is very promising, and many more companies are accepting this methodology due to the privileges. The methodologies are itself changing with new tools and technologies coming in. The careers in DevOps are bringing a revolution in IT industry with wide development and improvement.
