DevOps Tutorial

DevOps is Development and Operation's Collaboration; itís a Combination of Process, People and Working Product that enable continuous integration and continuous delivery of importance to our end users. DevOps speed up the process to distribute applications and software services at extraordinary quickness and high speed.

The DevOps seminar will help you to learn DevOps from scracth to deep knowledge of various DevOps tools such as

Linux, Git, Jenkins, Maven, Apache Tomcat, Nexus, Ansible, Chef, Docker, Nagios,  and Kubernetes.




About DevOps

The DevOps is a combination of 2 words, one is Software Development, and second is Operations. DevOps allows a single team to manage the complete application, from Software Development to Testing the Product and Deployment, and Operations.

DevOps helps you to reduce the interruptions between software developers, quality assurance (QA) engineer teams, and system administrators.

DevOps

DevOps encourages collaboration between Development and Operation teams to deploy product to production more rapidly in an automated and repeatable

DevOps supports to increase speed to deliver end user applications and application services. It similarly allows organizations to help their customers better and participate more powerfully in the marketplace.

DevOps can also be defined as a sequence of development and IT activities with better communication and collaboration. DevOps has become one of the most valuable trade units for firms or organizations. With the benefit of DevOps, the excellence and rapidity of application delivery have greatly improved

DevOps is nothing more than a method or method by which "developers" and "operations" work together. DevOps represents a shift in IT culture with a full focus on accelerated IT service delivery by adopting agile practices in the face of a system-based approach

DevOps is about the process of integration and development of operations. Companies that have adopted DevOps have seen a 27% improvement in software quality and a 25% improvement in application frequency frequency and a 40% increase in customer satisfaction. Successful DevOps implementation resulted in 30% revenue increase.

Importance of DevOps

1. Littler development phases, faster modernisation When we have a biased response from development and operations teams, it is difficult to tell whether the application is working or not. When development teams submit a request, cycle times can be unnecessarily extended.

With combined improvement and operations efforts, the teamís applications are ready to be used more rapidly. This is important because companies succeed based on their ability to innovate faster than their challengers.

Earlier going any more, we need to understand why we need DevOps over other procedures.
  • The operation and development team worked in complete isolation.
  • After design-build, testing and deployment are performed respectively. That is why they took longer than actual construction cycles.
  • Instead of using DevOps, team members spend more time designing, testing, and extending the project rather than building it.
  • Manual code expansion can lead to human errors in production.
  • Coding and operation teams have their own timelines and they are not synchronized, which can cause further delays.

History of DevOps

  • In 2009, the first conference named DevOpsdays was held in Ghent Belgium. Belgian consultant and Patrick Debois founded the conference.
  • In 2012, the state of DevOps report was launched and conceived by Alanna Brown at Puppet.
  • In 2014, the annual State of DevOps report was published by Nicole Forsgren, Jez Humble, Gene Kim, and others. They found DevOps adoption was accelerating in 2014 also.
  • In 2015, Nicole Forsgren, Gene Kim, and Jez Humble founded DORA (DevOps Research and Assignment).
  • In 2017, Nicole Forsgren, Gene Kim, and Jez Humble published "Accelerate: Building and Scaling High Performing Technology Organizations".

DevOps Features and Architecture

Here are some key features of DevOps architecture, such as:

DevOps Tutorial 4

1. Plan

DevOps use an agile methodology to plan growth. Unscheduled work always reduces productivity. Synchronizes with the development and operations team, which helps manage the workflow to create a plan that maximizes productivity.

2. Code

Many good practices, such as the widely used git, allow code to be used, which helps businesses not only write code, but also track changes, inform the reasons behind the change, and revert back to the original code if needed. The code can be set and reused in files and folders.

3. Build

Without DevOps, the cost of resource utilization is estimated based on a predefined individual consumption with fixed hardware allocation. With DevOps, cloud utilization, resource sharing comes into the picture, and the build depends on the user's need, which is the mechanism for controlling resource usage or efficiency..

4. Test

The application will travel to production after it is verified. In the situation of Manual Testing, it consumes additional time in testing and moving the code to production. Testing can be completed by automation, which reduces the time for testing, thereby reducing the time required to generate the code, because automating the running of scripts avoids many manual steps.

5. Operate

DevOps replaces the traditional approach of developing and testing separately. Teams work in partnership with both teams actively participating in the service lifecycle. The operations team interacts with the developers and they come up with a monitoring plan for IT and business needs.

6. Deploy

Most systems can support the scheduler for automatic deployment. The Cloud Management Platform enables users to capture accurate insights and analyze trends on the trends through the deployment of dashboards.

7. Release

Generally, deployment to the environment can be done through automation. But when the product is deployed to the environment, it is done by manual triggering. Most processes involved in release management usually require that the product be deployed manually in the production environment to minimize impact on customers.

8. Monitor

Continuous monitoring is used to detect any risks of failure. It also helps to track the system accurately so that the health of the application can be checked as well. Monitoring the log data with a number of third party tools such as Splunk / Nagios is easy with monitoring services.

Advantages of DevOps

Of course, there are benefits from cloud adoption, but there are also benefits of DevOps as a service:

Collaborative ease: With the development tools in the cloud, it's easy to collaborate with customers anywhere. And as a key contribution to the DevOps philosophy, this is a huge benefit!

Rapid testing and deployment: Generally, when companies use cloud services, it enables them to increase their release frequency. With more computing power and data storage, the cloud makes the process easier and faster.

Improved Documentation and Quality Control: Using cloud services is more data-driven so everyone on the team can use the same dataset. This leads to better documentation and quality control.

Associate with Internal DevOps: DevOps as a Service does not require you to have an internal DevOps deployment process. It makes it easy to offload different parts of the project for better collaboration and quick turnaround.

It's built-in IT: Many leading cloud providers have created DevOps tools within their features that work towards continuous delivery, and leading DevOps tools work with these cloud providers to help you get the results you need.

Disadvantages of DevOps

  • DevOps professional or expert's developers are less available.
  • Developing with DevOps is so expensive.
  • Adopting new DevOps technology into the industries is hard to manage in short time.
  • Lack of DevOps knowledge can be a problem in the continuous integration of automation projects.
