Legacy of the Development and Operation Show

I am Developer, I need a server…

now..!!!

I want access to the production

systems…No Access..! How can I work here?

Something is wrong in PROD…whose

fault is it?

So many alerts they are meaningless..

Get me the right one.

I don’t have time to save time…Too

many release stuffs and preparation

Our hero is a bottleneck…

I am inside of Scripts Hell…Help me…!!!

Dev + Ops DevOps

Two perspectives, but one defined Goal. DevOps brings in both parties together to deliver customer value in high velocity and continuously.

Less defect, faster delivery of feature

DevOps is the combination of culturalphilosophies, practices, and tools that increasesan organization’s ability to deliver applicationsand services at high velocity: evolving andimproving products at a faster pace thanorganizations using traditional softwaredevelopment and infrastructure managementprocesses. This speed enables organizations tobetter serve their customers and compete moreeffectively in the market.

Under a DevOps model, development andoperations teams are no longer “siloed.”Sometimes, these two teams are merged into asingle team where the engineers work across theentire application lifecycle, from development andtest to deployment to operations, and develop arange of skills not limited to a single function.Quality assurance and security teams may alsobecome more tightly integrated withdevelopment and operations and throughout theapplication lifecycle.

These teams use practices to automate processesthat historically have been manual and slow. Theyuse a technology stack and tooling which helpthem operate and evolve applications quickly andreliably.

DevOps Industry Challenges

Development and operations view the world fromdifferent perspectives. Although they are bothconcerned with the same outcomes, theirapproaches are different, like two sides of the samecoin.

Selling DevOps to developers isn’t too difficult – fordevelopment it’s easy to see the benefits to creativityand innovation made possible through DevOps.Operations, on the other hand, views DevOps withsuspicion, believing it is an attempted developmentcoup to enable developers to continually dumpbuggy, untested software into production.

There is a popular sports adage that goes, “There isno comfort in the growth zone, and there is nogrowth in the comfort zone.” DevOps requireschange. Change requires adaptation. Adaptationrequires learning new skills.

DevOps will require new workflows, which ifimplemented will cause a trickle-down effectthroughout the organization. Current tools willbecome obsolete, and investment in new tools willbe necessary to support new workflows.

DevOps will shift the power balance in theorganization, in some way or another. It’s inevitable,but not necessarily insidious.

DevOps lot of times is misunderstood ormischaracterized. Such as -DevOps replaces Agile, DevOps replaces ITIL, DevOpsmeans NoOps, DevOps is only for open sourcesoftware, DevOps is just “infrastructure as code” orautomation, DevOps is only for startups and unicorns
