VitAL MANAGEMENT


What needs to happen? A two-pronged approach is needed in order for DevOps to become a functioning reality. Firstly, Development needs to configure software in such a way that Operations is able to make last minute modifications in software production. Secondly, much greater automation must be used to support the release of the applications, particularly in the processes linking all of the relevant release stakeholders. This joined up approach characterises DevOps. Furthermore, a change in mind-set needs to


happen within both functions: Development and Operations working with each other’s goals in mind. Development has to take into account the kind of engineering for long- term stability implemented by Operations. Operations has to understand the development process, particularly if the development team uses agile methods. It must understand how to manage this potential flow of changes to applications or IT services coming out of development and be able to put them into production as seamlessly as possible. While Operations remains the guardian of uptime and response time, a further priority of ‘application update agility’ should also be introduced. This priority demands greater cooperation from both sides of the house and strengthens the case for DevOps. For DevOps to be a success, both Development and Operations need to work together on this joint priority at both the tactical and the strategic level.

Agility and market leadership The value that DevOps sets out to achieve is attainable today by companies that put agility and market leadership first. The ability to quickly translate new feature needs and ideas into reality, instead of waiting weeks or months for updated software, keeps companies nimble and ahead of their competition. What is essential is to look at the tools and people you currently have in place and then orchestrate them across the whole applications delivery process.


Given the increased reliance on applications, the greater complexity in application development and the demand


for increased accuracy


and efficiency, DevOps is the right approach to take. The handover between Development and Operations must be as smooth as possible. This can be achieved when both functions work more closely together and have an understanding of the goals each must achieve. A more joined up approach can also help keep those requesting the new applications in the loop, involving them at critical stages and making the likelihood of internal and external customer satisfaction much greater. The DevOps movement not only fills an obvious gap in the release management process, it helps IT deliver the results that business needs. VitAL www.serenasoftware.com


An aligned, business focused face can improve the perception of IT within its


organisation, helping to raise its role as a real business contributor. The kind of IT alignment brought about through the DevOps approach can benefit the business as a whole.
