DevOps (development and operations) is an
enterprise software development phrase used to mean a type of agile
relationship between development and IT operations. The goal of DevOps
is to change and improve the relationship by advocating better communication
and collaboration between these two business units.
DevOps is
the blending of tasks performed by a company's application development and
systems operations teams. The term DevOps is being used in several ways. In its
most broad meaning, DevOps is an operational philosophy that promotes better
communication between development and operations as more elements of operations
become programmable.
In its most
narrow interpretation, DevOps describes the part of an organization’s
information technology (IT) team that creates and maintains infrastructure. The
term may also be used to describe a culture that strategically looks at the
entire software delivery chain, overseeing shared services and promoting the
use of new development tools and best practices.

Productivity gains with automation and improved workflows
Devops is the engine of digital
transformation, the trend that will yield a modern, agile enterprise

The goals of
devops is to parallelize work. The
necessary seven steps need not be done sequentially .No longer Ops are only
responsible for maintaining the applications in production, and in devops, even
the developers maintain responsibility for applications in Prod
Enable a
parallel workflow in the heterogeneous world, Devops is an integration of
process and tools
When done right, the benefits are
phenomenal
DevOps Toolchain
New software
tools have sprung up to help organizations automate testing and create a more
streamlined development and release pipeline. Such tools include GitHub for
storing code, Puppet and Chef for configuration management, Nagios for
monitoring how changes to code affect the environment and Splunk for
operational intelligence.
DevOps as a
Service is a delivery model for a set of tools that facilitates collaboration
between an organization's software development team and the operations team. In
this delivery model, the DevOps as a Service provider collects disparate tools
that cover various aspects of the overall process and connects these tools to
work together as one unit.
Future of DevOps Career
Most
entry-level DevOps jobs require a degree in computer science or a related field
that covers coding, QA testing and IT infrastructure components. Higher-level
positions may require advanced degrees in systems architecture and software
design.
Red Hat is
one organization that offers DevOps certification.
