DevOps (Development and Operations)
We will know.
What is DevOps?
There are two teams in any organization in the IT sector; The development team that writes the code changes the code and updates it, and the other operations team, which performs software testing to find out if the software is working well or not, and release the software. These two teams need to work together for an IT company to function properly, and this is what DevOps do.
DevOps is
made up of two words; Development and Operations.
It is a methodology used in the IT sector. The function of this system is to
facilitate collaboration, communication and integration between technical
departments, thereby reducing the risk involved in manufacturing the service
and product offered by the company and also increasing the quality of service
and product. Simply put, this methodology improves coordination between the
development and operations team, which speeds up software development, testing,
and launching it into the market. The DevOps methodology focuses on product
delivery, quality testing, feature development and maintenance, which improves
the reliability, security, fast development and development cycle of the
company or organization's product and service.
DevOps is a way of doing things
that have established a simple mechanism in the IT sector which is taking the
IT sector to new heights. It is the fastest established and developed system in
the IT sector. This method is being used on a very large scale and it is also
effective in all respects.
DevOps toolchain
The process of the DevOps system is
called the DevOps toolchain, it is a process that represents the tasks
involved in the DevOps system.
1.
Plan: This is the
first phase of DevOps, in which the task, requirements, and business values of
the projects are reviewed.
2.
Code: In this
phase, the work is done according to its name, the work of software creation and design is done.
3.
Build: In this phase, the work of managing the
production and release of product's versions and storing the code for the
future is done, a variety of automated tools are used to do this work,
including Docker, Ansible, Puppet, Chef, Gradle, Maven, or JFrog Artifactory.
4. Test: In this phase of DevOps the code is tested continuously, the code is tested manually and automatically. Some of the tools for this step are JUnit, Codeception, Selenium, Vagrant, TestNG, or BlazeMeter.
Deploy: In this phase, the release of the product is managed and all the work of release is done.
6.
Operate: This stage-manages the software during
production.
7.
Monitor: In this
phase, we review the software release and its functions in production.
What are the 7 DevOps practices?
We know
how DevOps is the link between developers and operations teams, which helps
both to connect and work together. Now we will know how to practice DevOps. We will understand this through some steps.
Continuous development: This step
shows us that development should continue in Company.
Continuous Testing: This step indicates that the code should be
under constant testing as the code changes and get updates continuously.
Continuous Integration: In this
phase, configuration management is done with some development and testing
tools, so that it is known how ready the code being developed is.
Continuous delivery: This stage works to mix continuous development and
testing and develop them further.
Continuous deployment: This step
helps in the continuous release of the product. Since each product is
constantly changing and updating and we
should always keep the released product updated.
Continuous Monitoring: In this phase, the code and the
work done for it are continuously monitored.
Infrastructure as code: In this
phase, the software developer has to add or modify the code as required and
ensure that the software is fully usable. In this phase, the developers add the
infrastructure code. All this is done using a variety of tools.
DevOps Tools
By
DevOps tools, it is meant that those tools which are used in DevOps practice are
called DevOps tools. Just as SEO tools are used to do SEO,
similarly DevOps tools are used to work according to DevOps methodology. Many types of DevOps tools are used in the IT sector, but we will learn
about some special and highly used tools.
·
Gradle: Gradle is one of the most reliable tools. It appeared in 2009 and since
then its popularity has continued to grow. This tool is an incredibly great
tool that accepts code in c++, python and many other languages. This tool is accepted by IDEs like Netbeans, Eclipse and IntelliJ. Google also has accepted
it as a build tool for their android studio.
·
GIT: If we call Git the most popular tool in its sector, then it will
not be wrong. Git is used by developers. In this, they can save their code,
share the code. To use Git, you need a repository that you share with your
co-workers. There are currently two Git repo hosting services Github and Bitbucket.
Github is more popular.
·
Jenkins: Jenkins is
an automation tool that is popular with many developers. The reason Jenkins is
so popular is because of its thousands of plugins. That's why it integrates
with all other DevOps tools.
·
Bamboo: bamboo
also has many of the same features as Jenkins and it is also very popular but
it is a paid tool.
·
Docker: If you know even a little about DevOps, then you must have heard the
name of docker. Docker is considered one of the most essential DevOps tools.
docker can integrate with both Jenkins and bamboo.
·
Kubernetes: Kubernetes has become very popular in DevOps while it is a very new
tool, it was first seen in 2015. It has been invented by some software
engineers of Google who wanted a good tool to manage containers.
·
Ansible: Ansible is a configuration management tool. It is famous for its
simplicity.
Benefits of DevOps
We learned that this is a methodology that is playing an
important role in developing the IT sector. Now we will know the benefits of
DevOps.
Faster deployment: The DevOps system can release any project in a short time
because it helps the people working on the project to stay connected with each
other.
Stabilize work environment: With DevOps, the workplace
environment is completely stable as the people working on the project get a
settled environment.
Promotes agility in your business: There is a lot of agility in the work
of the project team by DevOps and it is not hidden that this is a good thing
for any business.
Continuous delivery of software: Due to DevOps, there is stability in
every work in the workplace, so that the work of software distribution is also
continuously running.
Minimal cost of production: Due to DevOps, understanding each
other's work in different teams of the project reduces the cost of the product
because both; Time and labour are also reduced.
Transparency leads to high productivity: Due to DevOps, easy communication is
developed among the employees, due to which the stress of the employees is
reduced, which increases the production.
