What is DevOps?
‘DevOps’ is a combination of two words ‘development and ‘operations’. DevOps tools help to increase an organization’s to deliver applications and services at high speed.
In simple words, DevOps can be defined as an alignment of development and IT operations with better communication and collaboration.
What are the benefits of DevOps?
The main benefits of DevOps are:
- More stable operating environments
- Faster delivery of features
- More time to innovate (rather than fix/maintain)
- Improved communication and collaboration
- Greater professional development opportunities
- Higher employee engagement
- Happier, more productive teams
- Faster resolution of problems
- Continuous software delivery
- Less complexity to manage
- Better collaboration between Teams
- Speed of deployments
- Lower costs
- Improved processes
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?
They are lots of change likely to happen in the DevOps world some of the most prominent are:
- Organizations are shifting in their needs to weeks and months instead of years.
- DevOps is becoming a valued skill for IT people.
- DevOps engineers have access and control of the end-user than any other person in the enterprise.

What is Agile?
Agile involves a continuous iteration of development and testing in the SDLC process. The agile development process breaks the product into smaller pieces and collaborates them for final testing. It can be implemented in many ways including kanban, scrum, XP etc….
Difference between Agile and DevOps:
|Agile helps to manage complex projects||DevOps conception is to manage the end-to-end engineering process.|
|Agile development gives importance to train all team members to have a wide variety of similar and equal skills.||DevOps spreads the skill set between the development and operation teams.|
|Agile famous tools are JIRA, Kanboard, Bugzilla.||Puppet, AWS, Kubernetes, Jenkins, Bamboo are famous DevOps tools.|
|Agile software development method emphasis on iterative, incremental and evolutionary development.||DevOps is a software development method that focuses on integration, communication, and collaboration among IT professionals.|
|Agile refers to an iterative approach that focuses on collaboration, customer feedback, small and rapid releases.||DevOps consider as a practice of bringing development and operations teams together.|
DevOps Automation Tools:
The best DevOps Tools For 2019:
Gradle is a flexible tool that allows you to write your code in python, c++, Java or other languages. It is also supported by popular IDEs such as Netbeans, Intellij IDEA and Eclipse. Gradle introduces a Groovy-based DSL for describing builds. The Gradle team released Kotlin-based DSL in 2016, now we can write your build scripts in kotlin as well.
Git is one of the most popular DevOps tools. Git is a distributed SCM (Source Code Management) tool. It allows you to track the progress of your development work and you can save different versions of your source code and return to a previous version when necessary.
Jenkins is an open-source CI/CD (Continuous Integration/ compact Disc) server that allows you to automate the different stages of your delivery pipeline. Jenkins has a huge plugin ecosystem. It offers more than thousand plugins. So, it collaborates with almost all DevOps tools from Docker to Puppet.
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 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 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.
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 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 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.
Nagios offers four open source monitoring solutions:
- Nagios Fusion
- Nagios Log Server
- Nagios XI
- Nagios Core
