How did DevOps happen?
• Till now, various companies treated product development, quality assurance,
and system operations as three different entities. In some companies, these
departments function like different organisations.
• But, with the advent of Cloud Computing, and Software Defined Networking
(SDN), the walls between aforementioned departments had to be destroyed by
an enterprise to remain relevant among users. This led to the creation of
DevOps.
• Many more enterprises are beginning to buy the idea of DevOps. With DevOps,
they are able to develop high quality codes in less time. With QA also in the
loop, quality is maintained throughout the product lifecycle.

Why is DevOps needed?
For Developer Teams
• With DevOps, developers can expect
less headaches regarding any issues
cropping up during the development
phase.
• Developers remain in touch with
their code from development to
implementation.
• Developers get to work in real time
environments, rather than
simulated situations.
For Operation Teams
• With DevOps, operations team can
easily deploy changes in the product.
• Due to proactive monitoring,
efficiency of error rectification gets
improved.
• Due to improved communication
between developers and system
operators, conflicts and differences
