What is DevOps?
Many people have varying opinions on what DevOps is defined as, and the answer you receive will depend on who you are asking. However, at a high level DevOps is simply the act of syncing the development and operation processes into a more collaborative process. It’s better to not think of DevOps as a single task or a tool, but as a culture that involves the use of a specific set of tools to ensure a fast change in a particular system while tracking and maintaining quality. These processes came into existence to bridge the divide between Dev and Ops and to smoothen the software delivery workflow.
While not every project will require heavy work on the development side, it is absolutely important for every engineer to have a healthy balance of both development skills and operational knowledge.It is better to have the knowledge, and practical abilities on different types of programming languages, and it is an added advantage if someone has an understanding of scripting knowledge. Almost all of the developers have a basic understanding of Linux since it is a widely used operating system for programmers.
- Proper knowledge of different types of programming and scripting languages. .
- Familiarity with the various open-source tools needed in day to day work.
- Knowledge of IT operations is essential.
- Testing and deployment of software code
- Understanding of VMs, containers and microservices.
- Knowledge of the infrastructure as code and related tools.
- The ability to work in a collaborative environment
This is an open-ended question with no right answer. The answer really depends on a person’s true passion and learning consistency. Since there is no proper course in schools and colleges related to the tools and processes surrounding DevOps, it can be hard to supplement that lack of knowledge.. On the other hand, there are plenty of external course providers that are training potential DevOps aspirants and equipping them with the skills to be successful.. Take KodeKloud for example, we have helped equip thousands of people with the tools and skills they need to become successful in the DevOps industry and helped many receive a range of certifications.
There is no universal benchmark set in stone for becoming a proficient DevOps practitioner. .The ability to get up to speed solely depends on an individual’s ability to learn new cocepts with passion and consistency. For some, it may take a decent amount of time and for others, it may come naturally.. Here atKodeKloud, we have a complete DevOps learning path set for learners interested in taking a deep dive into an education in DevOps.
The short answer is – anybody with a desire to learn about the culture and processes while obtaining a high earning potential can learn these skills. This can include:
- Self taught practitioners looking to enter a new field
- Computer science students
- Operations Engineers
- Software Developers
- Continuous integration
- Continuous Feedback
Continuous integration is a software development method in which the developers’ code gets integrated several times a day. Whenever a developer pushes changes to a repo, the changes are verified by an automated pipeline and checked for any errors or bugs based on a given test suite.
Continuous delivery comes after continuous integrationI and is the ability to introduce changes in the environment with every commit., thereby making the code ready for production so that it can be deployed to production on demand and as a routine activity. Code changes can be anything from new features, bug fixes, updates, configuration changes, etc. One important thing to note is that before any changes are made, safety checks are run by the CI pipeline so that bugs get detected before any issues arise.
Continuous Deployment is one step ahead from Continuous Delivery. This is where once the code is delivered and safety checks are passed, those changes are deployed into production automatically without approval from a developer.
- Plan: JIRA
- Build: Maven, Gradle, Docker, GitHub, GitLab
- Continuous integration: Jenkins, CircleCI, Travis CI
- Release: Jenkins, Bamboo
- Deploy: Ansible, Kubernetes, Heroku, Amazon Web Services, Azure, Google Cloud Platform
- Operate: Botmetric, Docker, Ansible, Puppet, Chef, Terraform
- Monitor: Nagios, Splunk
- Continuous Feedback: Slack
Jenkins is still considered as the most popular CI tool in the DevOps space. With Jenkins, it is effortless to achieve visual ops. To convert a CLI into a GUI button, click, wrap up the script as a Jenkins job, and it is done.
Docker is a tool for packaging and running containerized applications.
Ansible is an open-source software automation tool that automates software provisioning, configuration management, and application deployment.
Kubernetes is a powerful open-source platform for container orchestration that automates the deployment and management of containerized applications.
OpenShift is Red Hat’s open-source cloud development Platform as a Service (PaaS), which allows developers to create, test, and run their applications and deploy them to the cloud without any hassle.
A pipeline consists of code (Usually YAML) written by engineering teams to define steps that tools such as Jenkins should take during the CI/CD process.. The pipeline often goes through a process such as:
- Build the code
- Test the code, if the tests pass, deploy the application to the various environments like development, test, or production environment. A pipeline is a series of events or jobs that happen in a flow in the software delivery pipeline from start to the end.
