Every company follows a different methodology to achieve its goals. Nowadays, competition is rising day by day and companies should outperform in order to stay competitive in market competition.
Meanwhile, the tech companies are also increasing day by day. And the world’s top marketplace is mostly acquired by big tech companies like Apple, Google, Tesla, etc.
These companies are doing everything to make it more successful. Recently, Apple was declared as a first trillion company and others are also following it.
So, different thoughts might arise for you guys about what’s the best methodology for IT companies to adopt. And the answer is simple, that is DevOps.
What is DevOps?
DevOps is a software development approach where developers collaborate with the operational team in all the phases of the software development process. It includes product design, development, testing, deployment, and support.
Matter of fact, the need for competent software engineers is increasing as an increasing number of firms attempt to use DevOps principles.
Indeed, throughout the last several years, industry-led market research has constantly come to the same conclusion: DevOps engineering is the most in-demand IT profession at digitally-enabled businesses.
After all, if you want to be a DevOps engineer then no need to worry because we got your cover. Here is the complete DevOps learning roadmap for aspiring DevOps engineers:
Learn a programming language
There are different programming languages that help you to complete the DevOps learning roadmap. You guys must have heard about programming languages like Java, Python, JavaScript, etc.
Java is a good programming language and the motto of Java “write once, run anywhere” helps it to stand out compared to other programming languages.
Python is a popular programming language as it has a simple syntax and learning it is easy. If you guys are having a hard time because of syntax then Python is for you guys.
Moreover, JavaScript is a versatile programming language. Most of the websites are built with this programming language.
If you don’t know which one to select, then we would suggest you choose between Java, Python, and JavaScript. All of the three programming languages are popular languages and help you to become a better DevOps engineer.
However, having a clear understanding of certain programming language will help to create a better DevOps learning roadmap. Therefore, it will be easier for you to learn.
Knowledge about OS
Since to learn about Operating Systems (OS) and the person responsible for OS is the System admin but in the DevOps learning roadmap, you should also know about the foundation of OS. You, at least, need to know about some basics of OS like memory management, virtualization, threads, etc.
Matter of fact, in DevOps, “Ops” stands for an operational system. Thus, for DevOps engineers Operating System is also an important aspect.
There are lots of different courses available online but we would like you to recommend Linux Administration BootCamp.
Security and Networking
Nowadays, everyone should be an all-rounder as there is huge competition in the market. And in order to be perfect in the DevOps learning roadmap, you should know some basics about security and networking completely.
At least, you should know DNS, OSI Model, HTTP, etc. to be a good DevOps engineer.
Working environment
DevOps engineers should be good in every working environment. They should know about the setup in their machine and how it works.
Matter of fact, a DevOps engineer should know how to set up a Web Server like IIS, Apache, and Tomcat.
Learn some Continuous Integration and Delivery (CI/CD) tools
Another very important thing regarding the complete DevOps learning roadmap for engineers is to set up a pipeline for continuous integration and delivery. There are a lot of tools in the CI/CD area e.g. Jenkins, TeamCity, Drone, etc.
But, we strongly recommend you learn at least Jenkins, as it’s the most widely used and probably the most mature CI/CD tool in the market. If you don’t know Jenkins then this course is best to start with.
Learn to monitor software and infrastructure
Apart from setup and deployment, monitoring is another important aspect that falls apart in the complete DevOps learning roadmap and that’s why it’s important for a DevOps engineer to learn about Infrastructure and application monitoring.
There are a lot of tools in this space e.g. Nagios, Icing, Zabbix, Monit, AppDynanic, New Relic, etc. You can choose some of them depending on which one is used in your company like AppDynamic and Nagios.
Learn about Cloud Provides
Cloud is the next big thing and sooner or later you have to move your application to the cloud, hence it’s important for a DevOps engineer to at least know about some of the popular Cloud Providers and their basics.
While AWS is clearly the leader in the cloud it’s not alone, Google Cloud and Azure are slowly catching up and then we have some other players like Heroku, Cloud Foundry, and Digital Ocean.
Why is DevOps important?
DevOps is simply important because it helps to interact with developers and operational teams continuously in order to obtain the required outcomes.
However, there are also lots of reasons which make it important. They are:
- Less Error
DevOps helps to make fewer errors during the deployment of code. Because it helps to go through different iterative processes to successfully execute the code.
In addition, it also helps developers to share the piece of code which integrates with the shared repository.
- Effective and Efficiency
Complex and repetitive checking of executing code is done by automated testing which helps for efficiency. And automated testing also corrects the code as a result it helps to make it effective.
- Security
DevOps also helps to give us security. As it helps to repeatedly check the error while executing and making the resulting better outcome. Thus better outcome means better security of it.
- Less time consumption
Automation helps to consume less time as it is helpful for complex and repeatedly checking errors while executing code while processing.
In addition, it also helps to save time by taking outcomes from one department to another department by simply coordinating both teams initially.
Therefore, if you are thinking about building a career in the field of Information Technology, DevOps can be a fruitful path to take. And, in order to have a great DevOps career, a clear DevOps learning roadmap is vital.
