DevOps has become a platform for driving
business operations. The shift in business is rapidly growing and making use of
applications and websites for their company to help get their product and brand
out there. Principles of continuous integration and continuous build have
become an integral
part of modern DevOps.
If you're not currently doing these, you're behind the curve of collaborative
development and likely reducing your production quality by increasing technical
debt, substituting automated operations for manpower and increasing costs
The Devops movement is built around a group
of people who believe that the purpose of combining the proper technology and
approach can change the world of software development and delivery. Developers,
Testers, Managers, DBA’s and the rest of the specialist in the IT industry are
all on the same side. They are all trying to achieve the same thing: the
delivery of great quality, reliable software that delivers business benefit to
those who bought it.
It’s important to realize that merging
applications and infrastructure are extremely difficult. It has however become
part of how businesses bring their digital products to new customers. The
difference of opinion is increasingly solved through DevOps - a role that helps
to bridge the gap. However, there are other levels that must be reconciled in
order for the gap to be closed for organization to take advantage of the
benefits of incorporated development and operations.
What challenges need to be reconciled?
The app server perception
Time and again, application
developers go above and beyond what their needs are. From a hardware point
of view, questions need to be raised in relation to whether developers have
really understood the application’s resource requirements, for example what
needs to be run on the actual server that’s hosting the application.
Applications thrive on central processing
unit (CPU) and memory resources, and this often converts to resources
provisioning problems when the application is moved from testing to production.
Price and costs
The fact of the matter is that building quality
software is really expensive and difficult - it's error prone, it's risky, it's
unpredictable, so it’s important to consider the infrastructure cost on which
the application will be running on. Rushing to buy is not a good idea. If
there’s a break down between the dev and IT in terms of what application performance should entail, then you run the
risk that extra purchases may become necessary. That cost may end up being more
expensive separately than if it had been planned for at the beginning.
Sometimes the needs of the application must be repeated to infrastructure
people, so that it makes sense to them. Even when you think things are fine,
there is a need to translate from development to operations, since all too
often it’s as though the two departments are speaking different languages: IT
is talking about the hardware underlying the OS, while dev is talking about application
on whatever coding platform. On the application side, while a certain platform
may be in future use to build the app, it needs to be understood whether it is
the best-suited platform for the development process as it relates to a living
The fundamental problem is that from the application side, there is not always
the complete understanding of how the operating system at the
infrastructure level needs to support the application, which can result in a
memory leak for example, or another vulnerability that is causing a need for
more resources. From the infrastructure perspectives, it’s about ensuring that
all details are checked and double checked around potential drawback areas on
the OS, thereby helping integration. This issue can often be overlooked as you
go through different OS iterations. Certain businesses can’t patch their
servers because they don’t fully understand what needs to change on their end
in order for them to change anything related to the app. For example, a
security patch might fix one thing but it might affect something else and
degrade an app.
How do you reconcile the two competing
The more you integrate dev and IT, the bigger and
better results you will get. There are benefits to these different sides
matching in an organization -communication plays a crucial role in this. This
is as true on the application level as much as it is on the business level. Too
often the business needs are not accurately communicated to either group. The
business might speak to developers directly thinking that operations and dev
are the same, they’re not. And it needs to be approached in the same way to
better communicate exactly what is trying to be achieved. It shouldn’t be
information that’s passed between the groups like a game of volleyball.
A few suggestions that can help this
Yes, you might want to rush the project, but don’t just buy for what’s needed
now. Buy with the expectation that your company/brand will grow.
Be practical from a dev perspective for
creating an app: Though it might seem cool and
works in your testing environment, it won’t necessarily translate correctly or
impeccably in production.
Use best practices: Don’t cut corners, and make sure the app has been tested on the
infrastructure. Regardless of rush from the line of business, if it’s not
ready, it needs to be revisited and prepared on its own time.
