DevOps Training: What does the program consist of?

Over the years, computing has changed. Software users demand new features as quickly as possible, but also want stable applications without crashes or interruptions.

As a result, companies often have to choose between delivering changes quickly in an unstable production environment, or maintaining a stable environment and working more slowly. However, none of these options is acceptable to managers, and none allows us to offer the best solutions to customers.

Developers want to deploy their software more and more quickly, while operators want to preserve system stability. In order to resolve this dilemma, the DevOps methodology was created to reconcile everyone’s interests.

This approach is now predominant in the field of software development. In order to acquire highly sought-after expertise in business, learn to master Apache Airflow by following DevOps training.

What is DevOps?

DevOps unites software developers and operational IT teams into a single, highly automated workflow with a single priority: rapid delivery of high-quality software that meets all user needs while maintaining integrity and stability of the system.

This methodology is based on a cultural philosophy, and on a set of practices and tools. Its goal is to automate and integrate processes between software development teams and IT teams.

The main principles of DevOps are teamwork, communication, collaboration, and technological automation. Within a DevOps team, developers and IT operators collaborate throughout the product lifecycle. Their goal is to increase the speed and quality of software development.

It’s a new way of working, a cultural change with a heavy impact on teams and the organizations they work for. The development and operations teams no longer work in “silos” and can merge to form a single team with multidisciplinary skills.

In order to automate and accelerate processes, DevOps teams use different tools to increase reliability. These tools make it possible to adopt practices at the heart of DevOps such as continuous integration and delivery, automation or collaboration.

Why take DevOps training?

The DevOps methodology is increasingly adopted by companies. Therefore, learning DevOps through training has many benefits.

According to Forbes, a DevOps specialist earns an average of $106,734 in the United States. In the coming years, DevOps could be the main recruitment criterion for 46% of IT companies.

Obviously, learning DevOps also benefits your business. Fast delivery of software helps a business grow, and the operating environment is more stable.

In addition, product quality will be greatly enhanced. This approach also saves time and increases efficiency, while improving collaboration and communication between the development and operations teams.

Learning DevOps allows you to acquire a wide variety of skills, and therefore increase your value within the company. The specialist masters various tools and technologies for development, testing and deployment.

Therefore, this expertise makes it easy to find work since the number of DevOps professionals is currently insufficient to meet demand. It also offers the opportunity to progress more quickly in your career.

For scripting, DevOps teams use the programming language in particular Python, Git and GitHub for continuous integration and version management, Agile or even Jira.

For the data structure, we use NoSQL, PostgreSQL, DynamoDB or the AWS RDS cloud service. Replication and backup techniques must also be mastered.

Regarding architecture, the main tools used are Ansible, Bash REPL, Linux, or Amazon Elastic Compute Cloud. Deployment is done with Kubernetes and Docker for containerization, Apache Airflow, Terraform, GitHub Actions and AWS EKS. Finally, the tools used for monitoring are Sentry, Nagios and StackExchange.

Generally speaking, DevOps training allows you to learn the techniques and tools to automate the creation of servers or the production of an application, to manage data storage, to secure the deployment of an infrastructure, to manage containers and supervise the DevOps infrastructure.

At the end of the course, you will have all the skills required to work as a DevOps engineer. This expertise is in high demand by companies, and will open many doors for you in your professional life!

DevOps practices and methods

Several practices constitute the heart of the DevOps methodology. First of all, continuous integration involves automating the integration of code changes into a software project. This allows developers to frequently merge code changes into a central repository where tests are run.

As a result, DevOps teams are able to fix bugs faster, improve software quality, and reduce the time needed to validate and release new software updates.

Likewise, continuous delivery aims to automatically deploy code changes in a testing or production environment. It follows a continuous delivery pipeline, where builds, tests, and deployments are orchestrated into a single workflow.

Another principle of DevOps is alerting all team members if there is a problem in the deployment pipeline. Likewise, everyone receives frequent information on the health and performance of applications in production. Every member should be able to access the data they need to do their job as efficiently and quickly as possible.

Automation is also at the heart of DevOps. It allows teams to move faster in the process of developing and deploying high-quality software. A simple change to the source code directory enables a deployment, testing or build process, saving valuable time.

Another principle of DevOps is Infrastructure as Code. Rather than simply scripting the infrastructure configuration, this technique allows infrastructure definitions to be treated as code. Thus, provisioning, configuration and management of the infrastructure can be carried out quickly and consistently.

The microservices architectural technique consists of building an application in the form of smaller services, which can be deployed and operated independently. Each service has its own processes and communicates with others through an interface. It is precisely this independence that enables CI/CD and other DevOps practices.
