What is Dev-ops
The most common statement about dev-ops which you can find in most
blogs is that "Dev-ops is just the combination of development and
operation functioning together “but dev-ops is not limited to that, it isn’t
something that was created by one individual.
Dev-ops is a logical thinking of an
engineer who tries to integrate multiple tools available to automate his task
to fasten the production and delivery to be competitive in the market by
satisfying his end users.
Why Dev-ops
In this fast-growing world, to eliminate
the traditional method of development and operation which takes a lot of time,
dev-ops came into action.
As mentioned above, dev-ops is nothing but
the combination of development and operation functioning together in order to
build, test, and release software faster and more reliably. This in return
reduces a lot of manual work & cost.
Why
Organizations are influenced by Dev-Ops
●
It takes a lot of time for a product to go from
development to deployment in traditional method, whereas dev-ops provides us
continuous integration and deployment where each day you can push a new feature
to your product and surprise your customer
●
Full transparency and seamless communication
enable Dev-Ops teams to minimize downtime and resolve issues faster than ever
before.
●
Computers execute tests more rigorously and
faithfully than humans. These tests catch bugs and security flaws sooner,
allowing developers to fix them more easily, which in turn reduces the
surprises during the time of release.
DEVOPS LIFE CYCLE
The
life cycle of Dev-ops is called as CICD pipeline (Continuous integration and
continuous deployment).
The
first steps into Dev-Ops are about examining your organizational needs and
taking the steps necessary to bridge communication between your development and
operations teams. Achieving this is a challenge, but you don't have to get
there overnight. While Dev-Ops is in many ways about organizational culture,
identifying the right software tools is an important step as well.
There
are numerous software tools released by many organizations for the same work.
It’s important to choose the right one based on our needs.
There is a total of seven phases in the
DevOps lifecycle –
●
Continuous
Development
●
Continuous
Integration
●
Continuous
Testing
●
Continuous
Monitoring
●
Continuous
Feedback
●
Continuous
Deployment
●
Continuous
Operations
In today’s marketplace, there is a need for
rapid product development based on the customers feedback and requirement to
respond quickly to market shifts.
It is no more suitable to wait for one year
to add more features in the next release which in turn also creates extra
pressure on the operation to release a new version swiftly.
The DevOps movement arouses out the
critical need here for organizations engaged in continuous development and
responds more quickly to the changes.
SYSTEM ADMIN TO DEVOPS
Dev-ops engineers are system administrators
who are also interested in coding and move into the development phase where
they can improve the planning of test and deployment.
Dev-ops break the term departments and
overlap the role of development and operation into a single unit.
Out of the top skills which are
organizations looking in for a dev-ops engineer, it can be easily seen that
some of the skills such as scripting, OS admin, and monitoring are already
possessed by system admin. Other than the traditional approaches below
mentioned are some key things which a system admin should have in order to
become a DevOps engineer

MANAGEMENT
Micro services are one of the main futures
in the Dev-Ops technology. Most organizations have already started to use them
in the testing environment for the fast deployment of code.
Several software enterprises are pushing
toward microservices infrastructure. Microservices architect is an enterprise
solution, independently over a set of services.
Microservices are best suited for DevOps
due to its features including:
●
Isolated
nature
●
Improvised
cycle times
●
Well-defined
interfaces
●
Aligned
architecture
Containerization also is growing in
popularity. Containers are designed to run one process at a time with minimal
deployment, serving as an ideal deployment model.
If an enterprise has decided to leverage
microservices and containers, it is highly essential to incorporate solutions
that support microservices and containers along with traditional application
model.
To
sum up dev-ops was once an emerging branch but now
it has become a necessity.
