Devops 101

We all agree that it would have been wonderful to have someone to mentor us and provide basic information before starting a career in any profession. Peakin is here to give you a basic understanding of DevOps today in this blog so you can enter the DevOps industry more confidently. Peakin guides you effectively  to serve as an organization’s internal commando team, working to resolve a variety of issues and, also practically provides you with the knowledge which is required to smooth operation of a project. Before you read this blog it is better if you get a basic knowledge on what DevOps is. Check out our latest blog on Devops.

DevOps values

There are a few fundamental ideas driving DevOps. They are broadly divided into:

Automation: A big part of DevOps is automating as much as you can. This can speed up deployment and cut down on time spent on tedious, repeated operations. For instance, a DevOps team may automate testing procedures to give engineers early and regular feedback.


Culture: A strong sense of improved teamwork, experimentation, and constant learning is frequently associated with a successful DevOps culture. This could entail teams making sure that time is set aside to enhance work, rewarding teams for taking risks, and allowing members to learn from people both inside and outside of their teams.

Systems thinking: Systems thinking is the process of considering an entire system’s performance as opposed to just one team’s performance. This way of thinking makes sure that everyone feels accountable for providing high-quality work and deters teams from forwarding flaws to other teams.

DevOps techniques

Few essential practices.

Continuous integration and continuous delivery (CI/CD) are frequently used interchangeably. Continuous deployment extends these best practises by including a routine of real-time monitoring, testing, and updating products after they are released.


Continuous integration (CI) refers to the process of continuously incorporating fixes and stakeholder feedback into a product. This can entail both automating procedures for integrating patches and fostering a culture that encourages continuous integration.


Continuous delivery (CD) is the process of automatically integrating changes to a product (usually your code) so that it is constantly in a deployable state. This implies that code can be implemented quickly.

Guidelines for Starting

Learning DevOps Technologies and Tools


DevOps requires a strong understanding of Continuous Integration and Continuous Delivery since it makes it possible to develop and deliver high-quality software to clients on schedule. Continuous integration involves integrating new or fully working code into existing code. By doing this, time that would have been used for project integration is effectively saved. Then, with the least amount of manual work possible, Continuous Delivery gets the code ready for deployment.

Configuration Control

Engineering teams may create robust and dependable systems by using technologies that automatically manage and monitor changes to configuration data. This is possible thanks to configuration management. Complex software systems are made up of parts that vary in complexity and granularity. The three most important configuration management tools are Puppet, Chef, and Ansible.


Continuous monitoring refers to the process and tools required to incorporate monitoring into each stage of your DevOps and IT operations lifecycles. It is beneficial to ensure the health, performance, and dependability of your application and infrastructure as they transition from the development stage to the production stage. The concepts of Continuous Integration and Continuous Deployment (CI/CD) are the foundation of continuous monitoring. CI/CD enables you to develop and deliver software more rapidly and reliably, allowing you to provide continuous value to your customers. Tools like Nagios, Zabbix, Splunk, and others are frequently used

Source Code Management

The coding for source code management is frequently generated and altered by developers. Software for source code management makes it easier to save code, merge new code into older code, track code versions, and other tasks. It also makes it easier for team members to work together on source code. Git, GitHub, and Gitlab are the most popular tools for this purpose.

Containerisation Technology

Containerisation is the process of virtualizing an operating system such that multiple containers running separate applications can share the operating system and system resources. In the typical kind of hardware virtualization, when multiple virtual computers use the same system hardware, this is completely different. The primary providers of containerization are Docker, Kubernetes, and vagrant. As a result, a DevOps engineer must be familiar with containerisation technology.

Mastering Infrastructure as Code Configuration & Management

In data centres, server, storage, and networking infrastructure are managed using infrastructure as code (IaC). Large-scale configuration and management are made simpler by IaC. In contrast, the typical data centre mostly relies on human intervention for infrastructure administration and configuration modifications.

Soft Skills development is essential.

DevOps engineers need to excel at both teamwork and communication in addition to having strong technical skills. You must have exceptional listening skills in order to fully understand and appreciate what the client requires. Taking ownership, practising restraint, and keeping a positive outlook are all traits that benefit team members and eventually impact the success of the application.

 In order to find important areas for development and to understand the goals, DevOps demands bravery and attention. To understand and value what others have to say, as well as to prevent team conflicts, empathy is a necessity. The standard of the delivered product can be raised by encouraging trust among team members through active, transparent, and effective communication.

Why Does DevOps Matter So Much?

Efficiency gains from a good DevOps implementation can have a big influence on your company. Each of these components—the sort of engineer, the collection of procedures, and the culture—is covered by devops. Even though it is helpful to start by examining them separately.They are able to actively develop and enhance the systems through software development in addition to maintaining the servers, networks, and other infrastructure systems a company may have.
