What is DevOps?
DevOps may be referred to as the combo of tools, practices and cultural philosophies that are responsible for increasing the ability of an organization when it comes to delivering services and applications at a higher pace. This is done by improving and evolving the products more swiftly in comparison to the organizations that make use of the traditional infrastructure management and software development processes. In this DevOps tutorial, we are going to understand that expedited rate of production allows various organizations to compete in the market more effectively while serving their customers with better services.
How DevOps Model Works?
In DevOps models, operations and development teams aren’t siloed or isolated from each other. As a matter of fact, sometimes they are merged together to form one team whose members take care of everything starting from the development of the system to testing its final functionalities. In addition to this, they also work on developing certain skills that go way beyond just a single function. Security and QA teams also tend to integrate more tightly in the process of operations and development in the whole application lifecycle.
The teams make use of certain automation processes and techniques that have known to be slow and manual traditionally. They are used in a more effective and efficient way to get better results. Some specific tooling along with a technology stack is used to evolve and operation applications more reliably and quickly. Moreover, the said tools and techniques also turn out to be helpful for engineers when it comes to accomplishing certain tasks independently while otherwise they would have needed facilitation from several other teams to carry out the job.
What are DevOps Essentials?
The word DevOps may be thought of as an umbrella term. It may be referred to as an evolving practices set for enabling applications to grow and refine elegantly as if they were meant to be changed and refined eventually. In other words, it may be thought of as a convergence of specialty tools, engineering knowledge and internet afforded acceleration to bridge the gap between developers and tools, platforms, open source components and a world full of other developers. Certain essentials of DevOps are mentioned below for your better understanding.
The first and most basic DevOps essential is the fact that it is based upon architectural patterns, principles and conventions related to the integration, verification, development and deployment of the software as well as the related infrastructure. In short, using DevOps, software may be evolved more efficiently and economically.
DevOps provide direct access to all as its architectural capabilities are infused into different open source tools like component repositories and task managers. The tools make use of efficient and effective divide and conquer strategy for taking care of development complexity and transforming it into coordinated packaged tool solutions.
Source Code Management Automation
Without using a good source code management automation tool, you won’t be able to take care of your project efficiently. You won’t be able to maintain your command chain, track your work progress, make use of separate testing environments and support your development life-cycle among other similar issues. Therefore, making use of a good tool is highly important when it comes to SCM automation. GIT is one of the best distributed version control systems you may find in the market for this purpose. It is an open source system developed for handling small as well as massive projects swiftly, effectively and efficiently.
When a developer is willing to use GIT for automation of source code management, it is necessary for them to integrate GIT into the entire DevOps process of their enterprise as it is an important requirement for GIT to provide the functionalities of automated compilation, promotion and testing of their code.
Continuous integration may be referred to as a process that integrates all the development work as quickly as possible. The artifacts are created and tested automatically as a result of the process. It also allows users to identify bugs and errors more quickly in comparison to other techniques. Jenkins is known to be one of the most popular tools used for build automation and continuous integration. All it does is execute the list of predefined steps for compiling the source code in order to build a Java Archive using the resultant classes. Some of the most common steps followed by Jenkins to complete the continuous integration process are as follows.
- Using gradle or apache maven for carrying out a software build
- Executing shell scripts
- Archiving build results
- Evaluation using software tests
Understanding Containerization using Docker
Docker may be referred to as an open source software tool designed to facilitate the deployment of applications using containers. Containers are made using packages of applications. Later, they get shipped to the required platform where they are required to perform their functionalities.
Containers are highly popular among developers as they help them out when it comes to packaging applications along with all essential necessities. An individual easily usable package is developed and shipped to the required destinations.
Docker containerization may be referred to as a method which breaks down an application into several sizes that are easy to manage. They are individually packaged and completely functional along with all of the dependencies that are built into them. Using the technique of Docker containerization, the whole process of scaling and application as well as updating every single one of its components becomes much more easy and convenient.
More about DevOps and DevOps Essentials
DevOps features a cross functional working mode which requires it to make use of multiple tools at the same time rather than relying upon just one of them. Some of the most commonly tools used in the DevOps process are given below in order to give you an overview of its functionalities.
- Code development, review
- Source code management
- Software build using continuous integration tools
- Software testing
- Software packaging using artifact repository
- Change management
- Configuration of infrastructure
- Software performance monitoring
Hopefully this DevOps Tutorial gave a good understanding about DevOps, how it works? DevOps essentials, understanding source code automation, continuous integration, containerization and related concepts.
