Beschreibung

“It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.”- Charles Darwin

As the industry is moving towards maximum digitization there is a consensus that DevOps practices help you deliver software faster, more reliable, and with fewer errors.

DevOps is set of practices and cultural values that have been proven to help organizations of all sizes improve their software release cycles, software quality, security, and ability to get rapid feedback on product development.

This book is aimed at Consultant, Project Manager and people from techno-commercial profiles who would be explaining the benefits of DevOps to the client, internal leadership or project teams. As the crux of DevOps methodology lies in the cultural transformation of the organization, people who are stakeholders in shaping this change must understand the overall alignment of business goals with this methodology.

You would get to explore:

• What is DevOps
• Relationship between Agile, Scrum, Kanban and DevOps
• DevOps Adoption:  Organizational cultural Change
• DevOps Ecosystem
• Emerging Trends
• DevOps success stories

In the Bonus Booklet you will find out:

• DevOps Job Market overview
• Insights into DevOps job application
• People to follow on twitter

Introduction

DevOps is the buzzword these days in both software and business circles.  Why?  Because it has revolutionized the way modern businesses do business and, in the process, achieved milestones that weren’t possible before.  And in this book, you’ll learn what DevOps is, how it evolved, how your business can benefit from implementing it, and success stories of some of the world’s biggest and most popular companies that have embraced DevOps as part of their business.  It is my hope that by the time you’re done reading this book, you’ll have a good idea of how DevOps can help your business grow. 

So if you’re ready, turn the page and let’s begin.

What Is DevOps?

DevOps – or development and operations – is a term used in enterprise software development that refers to a kind of agile relationship between information technologies (IT) operations and development.  The primary objective of DevOps is to optimize this relationship through fostering better collaboration and communication between development and IT operations.  In particular, it seeks to integrate and activate important modifications into an enterprise’s production processes as well as to strictly monitor problems and issues as they occur so these can be addressed as soon as possible without having to disrupt other aspects of the enterprise’s operations.  By doing so, DevOps can help enterprises register faster turnaround times, increase frequency of deployment of crucial new software or programs, achieve faster average recovery times, increase success rate for newly released programs, and minimize the lead time needed in between modifications or fixes to programs. 

DevOps is crucial for the success of any enterprise because, by nature, enterprises need to segregate business units as individually operating entities for a more efficient system of operations.  However, part of such segregation is the tendency to tightly control and guard access to information, processes and management.  And this can be a challenge, particularly for the IT operations unit that needs access to key information from all business units in order to provide the best IT service possible for the whole enterprise.  Simply put, part of the challenge in segregating business units into individually operating ones that are independent of each other is the relatively slow flow of information to and from such units because of bureaucracy. 

Moving towards an organizational culture based on DevOps – one where the enterprise’s operations units and IT developers are considered as “partners” instead of unrelated units – is an effective way to break down the barriers between them.  This is because an enterprise whose culture is based on DevOps is one that can help IT personnel provide organization with the best possible software with the least risk for glitches, hitches, or problems.  Therefore, a DevOps-based organizational culture is one that can foster an environment where segregated business units can remain independent but, at the same time, work very well with others in order to optimize the organization’s efficiency and productivity.

Key Principles

One characteristic of DevOps is that it isn’t grounded or dependent on stringent processes and methodologies.  It’s based more on key principles that allow an enterprise’s key business units to efficiently work together and, in the process by breaking down any “walls” that may prevent optimal working relationships among such units.  These key principles that guide an enterprise’s DevOps are culture, measurement, automation and sharing. 

Challenges Solved By DevOps

Just before the development of DevOps, it took several teams to collate the necessary data and informational requirements as well as writing code.  After that, another team – a QA team – performed tests on new codes in a separate software development environment once the necessary requirements were met.  Eventually, it’s the same QA team that releases the new code for deployment by the enterprise’s operations group.  After that, the deployment teams are divided further into groups referred to as “silos” which include database and networking.  And if you consider all the teams involved with the development and deployment of just one code, you won’t be surprised why many enterprises suffer from project bottlenecks. 

With such a set up, several undesirable things happen.  One is that developers often become unaware of roadblocks for Operations and Quality Assurance that may keep the new programs from working as they were designed to work.  Another thing that may happen is that as the QA and Operations teams work on so many features of the program, they may not have a true understanding of the purpose and value of the programs that are being developed/tested, which may keep such teams from effectively doing their work on such programs.  Lastly, inefficiency and unnecessary backlogs are highly probable given each team or group has their own goals and objectives to achieve, which often times oppose those of the other groups, as well as the tendency to absolve themselves of responsibility for things that go wrong.

With DevOps, these potential problems can be addressed via creation of cross-functional teams that collaborate and share a common responsibility for maintaining the systems that are responsible for running software and other programs, as well as for prepping up the software so that they run on said systems with excellent feedback mechanisms for possible automation issues.
