Patrick Debois coined the term “DevOps” as part of the first DevOpsDays nearly 5 years ago. Now DevOps is a major movement in the smallest start-ups and the largest enterprises.

Myth: Errors happen: It’s software

Errors do occur. They occur for a reason. Often those reasons are out of our control. Someone changes an IP Address of a server. Someone changes the password to the back office system. Someone changes the name of a shared .DLL.

Of course in a well-managed and carefully controlled environment those kinds of things shouldn’t happen without the proper authentication, notification and approval. And the infamous “someone” is a responsible professional who calculates the impact of their changes and collaborates with everyone to minimize that impact. In a perfect world.

In the real world change is constant and calculating the consequences of change

As the DevOps movement approaches its 5 year anniversary, the question remains: is the movement ready to cross the chasm into mainstream IT? 

Stories of unicorns abound, and if we believe the vendors and early adopter case studies for the enterprise, we would be feeling that we are on the other side of the chasm, ready to get inside the tornado, change the culture and

Myth: Each deployment needs me

Helicopters have been described as “10,000 parts flying together in close formation. It is the mechanic’s job to keep that formation as tight as possible.”

Modern software applications comprise of millions of parts when you consider the huge chunks of code we bind into our applications from the database, security, web server, communications, encryption and authentication vendors. Add to that the seemingly infinite numbers of dependencies on external web services and internal CRM and financial systems.

There are 100 million lines of code in the Ford Taurus

But, just like the helicopter’s mechanic, the

Myth: Emergency fixes are different

“I don’t want to know why it happened: I just want you to fix it!” was what I was told early one morning by the Director of Sales. And she was right: getting the online store back online was the most important thing for the business. Blamestorming would come later.

There is a temptation at 3:00 am to just do whatever it takes to bring the system back on the air even if that means bypassing protocols and procedures designed to protect system integrity. Sales-and-Marketing and Audit-and-Compliance might not see eye-to-eye on this approach.

So why do emergency fixes have to be different? This myth is all about time. The time it takes to write the script.

Myth: Every target is unique

When we started this series we talked about how release engineers have difficulty in keeping up with the rate of change in their environment. Every day a new security patch or software update is applied that changes the known topology of one or more deployment targets.

This is why, some release engineers insist, they have to hand-craft the deployment scripts each and every time.

In an ideal world every target environment would be standardized. But we don’t live in an ideal world. Whether it is our own on-premise platforms, virtualized or cloud platforms we know that their configurations are in a state of constant evolution. This makes it hard for release engineers

The third day of the expo started at 10:30 this morning. It was very quiet competing against a very full and interesting agenda in the general sessions.

It was very rewarding to see so many customers come by and talk about their experiences with ChangeMan ZMF. We had one customer, who had been working as a ChangeMan ZMF Administrator for over 20 years, come by with his intern, a young college graduate who was being trained to take over from him when he retires. It was very moving to see one generation handing off to the next.

SHARE runs a fun competition for the attendees with some excellent prizes. They asked us for a question to add to their quiz and so we asked, “ChangeMan ZMF has been the
