Most companies have started adopting DevOps practices making DevOps Engineer one of the most sought after roles in the IT sector today with a very good salary for the DevOps engineers. So what are the DevOps engineer skills that organizations are looking for? Let’s discuss the six most essential DevOps skills sought after by companies seeking to hire
Most Demanding DevOps Skills
1. Linux Fundamentals And Scripting
Gone are those days when companies worried about proprietary operating systems. We are now in the era of Linux. Most companies prefer hosting their applications on Linux. As such, skills in handling a Linux operating system are very crucial for a DevOps Engineer.
Additionally, most configuration management tools like Puppet, Chef, and Ansible have their master nodes running on Linux. DevOps is a form of automation and includes automation for Infrastructure provisioning.
So, a DevOps Engineer must be able to handle any scripting language and must be well-versed with at least one scripting language (preferably Python). So the inevitable DevOps skillset would be Linux and Linux based scripting.
2. Knowledge On Various DevOps Tools And Technologies
DevOps practices are executed in various stages, and each stage has tools that can facilitate that stage. The main stages are
1. Source Code Management
Developers create and modify the software codes regular. Source code management software is used to store the code, merge new code to the old one, control the code versions, etc. It also helps t collaborate source code between team members. Tools like Git, Github, Gitlab are the most common for this purpose.
2. Configuration Management
Configuration management is used to keep track of software and operating system configurations. It also helps to manage configurations across thousands of servers. It is done through a click of a button or the execution of a single command on the management server. The configuration management tools take a remote connection to the target servers and push the configuration changes making life easy and simple. Puppet, Chef, and Ansible are the top players for configuration management.
3. Continuous Integration
Continuous integration, abbreviated as CI, is the process of automating the code integrations from different developers into a single piece of software. Jenkins and Bamboo are the main tools for Continuous integration.
4. Continuous Testing
Continuous testing is the process of reducing feedback waiting time after code testings. The code is tested in the development environment itself using automation testing tools. Selenium, TestComplete, and TestingWhiz are the most common tools for Continuous testing.
5. Continuous Monitoring
Continuous monitoring is used to monitor application performance, downtimes, error logs, etc. The main tools used are Nagios, Zabbix, Splunk, etc.
Containerization is the process of virtualizing an operating system so that different containers running different applications can share the operating system and system resources. This is opposed to the traditional way of hardware virtualization wherein the system hardware is shared among different virtual machines. Docker, Kubernetes, and vagrant are the top providers of containerization.
3. Continuous Integration And Continuous Delivery
Continuous Integration And Continuous Delivery or abbreviated as CI/CD is the essence of DevOps. It is the practice of continuously integrating all the code from different developers, continuously testing them, and deploying the successful code to production. Deploying to production will mostly require spinning up new containers, which is again automated using scripts.
4. Infrastructure As Code
Previously provisioning IT infrastructure was a long, tedious, and manual process. With the birth of cloud computing and containerization technologies, the infrastructure needed by developers can be provisioned through an automated script. The script executes the required commands and does the configuration management using one of the configuration management tools. The required application platform or infrastructure is delivered in seconds.
5. Key concepts of DevOps
DevOps unlike what people think, is neither a technology nor a tool. It’s a methodology that doesn’t have a strict framework. So companies can adopt the methodology by tailoring the framework as per their standards. The DevOps methodology’s main target is to bring the Development and Operations teams together to reduce the gap between them so that work is performed faster. Using DevOps methodology, companies are able to deliver quality software much faster. All the tools and techniques we discussed above are used to implement this methodology and deliver software products on time.
6. Soft skills
Soft skills play a great role in the IT industry with the adoption of DevOps methodology. Most companies prefer an Agile way of working using DevOps methodologies so that teams work in high velocity and produce deliverable faster to meet client expectations. So soft skills are ever more required when working in the DevOps world.
