DevOps - Defined

DevOps is a portmanteau of “development” and “operations”

Development + Operations = DevOps

Portmanteau is a combination of two (or more) words and their definitions, into one new word.

DevOps is a software development method that stresses communication, collaboration and integration between software developers and infrastructure operations professionals.

DevOps is in response to the interdependence of these two groups and aims to help an organization rapidly produce software products and services by bringing them closer together.

Similar to how Agile helps to bring business and development together to achieve quicker, better, cleaner business value. DevOps intends to do the same with development and operations.

DevOps integration tends to target the following areas... - product delivery - quality testing - monitoring and metrics - maintenance releases

all in an effort to improve reliability and security and provide faster development and deployment cycles.

DevOps - Defined

It’s origins stem from both the Enterprise Systems Management and Agile software development movements. First being popularized in 2009 and growing ever since.

- Co-location of teams where the development and operations teams are brought together into the same space and work together on a daily (or close to it) basis.

- Team resources grow their knowledge of the processes and tools so that they become an integrated part of the normal routine.

What if we approach projects with the ops side as the focus, rather than the normal dev focus.

Perhaps getting the business talking with ops as a starting point before all the rest?

DevOps - Possibilities

Wednesday, June 4, 14

NoOps - Two theories behind this...

- We establish a process through Cloud Infrastructure-as-a-Service or Platform-as-a-Service to provide the resources needed.

- Get the people and knowledge to be part of the team and break-down the walls that are dividing them.

DevOps - Possibilities

DevOps - Why

As with Agile being less about any prescriptive tools or practices...

DevOps also is beyond them, it’s more about the collaboration between the development and operations teams and the efforts to more effectively drive business value.

What can you do to make DevOps a reality in your organization?

DevOps - Challenge

- What if devs invite ops into your stand-ups or your planning sessions.

- How about the reverse and you brought some devs into the ops context?
