The idea of continuously delivered, quality software vetted through a collaborative and highly automated series of steps from inception to deployment is an enticing one, hence the appeal of DevOps. However, while just about everyone says they are pursuing DevOps, the reality on the ground has been mixed at best. The urgency of DevOps has only increased over the past year, as the Covid crisis scattered corporate workforces and physically separated IT teams. "We need to rethink connection and integrations, both on a technical level and a human one," says Ed Macosky, head of product at Boomi ."While it may seem that many DevOps teams don't have any trouble working remotely, two out of five said that remote work is affecting their ability to innovate and be creative, with the majority noting this is due to a lack of in-person connection with colleagues. DevOps teams bring innovations to life at a company."
In many organizations across all industries, the core value of the business is now being delivered through software. For decades, software was carefully planned and then developed and delivered in lockstep processes (called phase gate or waterfall) that mirrored other disciplines such as architecture: planning, followed by design, then development, which was then handed off to testing and QA, and finally to operations for maintenance. This carefully orchestrated process with predefined deliverables and several strict hand-offs worked well enough for a time but did not allow for flexibility, changing requirements, or--most importantly--an increasingly competitive landscape that demanded speed in the way we deliver software that allows us to respond to customer demands and security threats. DevOps is a software development and delivery methodology that provides exactly this: increased speed and stability while delivering value to organizations and customers. The methodology has come of age in the past several years, and organizations are adopting key DevOps practices--which include technology practices, processes that draw from the lean and agile movements, and culture--to transform their software practices.
Uplatz provides this comprehensive training on DevOps covering four of the most important and popular elements constituting an integrated DevOps system. The term'DevOps' was introduced by combining software "development" (Dev) and "operations" (Ops.) The aforesaid term was coined by Patrick Debois in 2009 to make way for quick and effective delivery of software updates, bug fixes, and features. DevOps, essentially as an approach or a work culture, is implemented by the right amalgamation of collaboration, automation, integration, continuous delivery, testing and supervising. Prior to the introduction of DevOps, the traditional or classic waterfall model was followed for software delivery. This process model involved a sequential flow of a defined set of phases where the output of one phase becomes the input of the next phase.
Sometimes, however, I have a hard time talking about DevOps. The reason is because many of the key terms related to DevOps lack clear and precise definitions. DevOps is such a big deal that it has bred its very own lexicon. Search Google for "DevOps terms," and you'll find a slew of "dictionaries" and "glossaries" dedicated to defining the various terms that go hand in hand with DevOps. Yet despite these resources, some deep ambiguities remain regarding the actual meaning of various terms that you hear frequently in DevOps-centric conversations.
