Faster delivery of features
More time to innovate (rather than fix/maintain)
Improved communication and collaboration
Cultural Benefits:
Greater professional development opportunities
Higher employee engagement
Happier, more productive teams
Technical Benefits:
Faster resolution of problems

Why is DevOps needed?
Before DevOps, the development and operation team worked in complete isolation.
After the completion of designing-building takes more time for Testing and Deployment without using DevOps.
Without using DevOps, team members are spending a lot of time in designing, deploying and designing instead of building the project.
Manual code deployment leads to human errors in production.
What Is the Future of DevOps?

It offers more than thousand plugins. So, it collaborates with almost all DevOps tools from Docker to Puppet.
Bamboo:
Bamboo is very similar to Jenkins. Bamboo has many pre-built functionalities that you have to set up manually in Jenkins. Bamboo can save a lot of configuration time. It also comes with a more intuitive UI with tooltips, auto-completion, and other handy features.
Docker:
Docker is a software platform that allows you to build, test and deploy applications quickly. Docker as one of the most important DevOps tools out there. You can use Docker containers instead of virtual machines such as VirtualBox.
Kubernetes:
Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services that facilitates both declarative configuration and automation. Kubernetes services, support, and tools are extensively available.
Kubernetes has a number of features. It can be thought of as:
a container platform
a microservices platform
a portable cloud platform and a lot more.
Puppet:
The puppet tool allows you to manage your infrastructure as code. It also provides developers with an open-source tool for small projects. With the puppet tool, you can manage multiple teams and thousands of resources. It deals with dependencies and handles failures smartly.
Extra features of Puppet Enterprise:
Node management
Real-time reports
Role-based access control
Ansible:
Ansible is a configuration management tool. It is similar to the puppet. Ansible uses the YAML syntax. With Ansible, you can define tasks in YAML. Ansible is a secure and lightweight solution for configuration management automation.
Nagios:
Nagios is one of the most popular free and open-source DevOps monitoring tools. With, Nagios you can keep records of events, outages, and failures. You can also keep an eye on trends with the help of Nagios’ graphs and reports. This way, you can forecast outages and errors and detect security threats.
