  • Perform Continuous Integration (CI) that involves building and testing applications.
  • Perform Continuous Deployment (CD) that includes releasing and deploying applications.

All these skills are discussed in detail later on in the guide.

  • Collaboration and communication:

A lot of times, there could be differences of opinion between the software development and IT operations teams. Therefore, it is the core duty of DevOps engineers to communicate and collaborate effectively between the teams.

He also communicates with the stakeholders and represents both the teams of development and operations. An individual with excellent soft skills can easily build a successful career in the DevOps field. 

  • Problem-solving and analytical thinking:

As a DevOps engineer, you can come across various technical issues that need excellent problem-solving skills. A lot of times, you need to perform root-cause analysis and develop quick solutions for the problems. 

At the same time, analytical skills aid DevOps engineers to analyze data, metrics and errors in software systems and operations. It is important for DevOps engineers to make data-driven decisions that can optimize software systems and infrastructure.

  • Continuous learning and adaptability:

A DevOps engineer has to proactively learn new technologies, tools and methodologies to improve workflows and optimize the productivity of the teams. Continuous learning and upskilling are crucial for a DevOps engineer to stay ahead of the curve.

Exploring the technical skills to become a skilled DevOps engineer:-

There are a defined set of DevOps engineer skills required to become a future-proof DevOps engineer in the industry. You must be fluent in working with certain tools and technologies to carry out technical processes such as troubleshooting, optimizing systems, etc.

The following technical skills are crucial to have as a DevOps engineer:

  • Infrastructure as Code (IaC):

It is the duty of a DevOps engineer to use Infrastructure as Code (IaC) resources to automate codes to design and deploy infrastructures instead of manually raising a ticket to run servers. This allows the existence of optimized automated servers and thus, makes the process of pushing applications to the cloud servers easy.

  • Automation and scripting:

Whenever a product or application is tested, code automation tools such as Selenium, etc. are used to look for code functionality, efficiency and user satisfaction. This is why it is important for a DevOps engineer to know how to automate tasks.

To automate the code-testing process, you must know how to code using scripting languages. These languages include Python, PHP, Ruby, Java, Golang, etc. The process of automation can bring quick outcomes and reduce manual loads on the teams.

  • Cloud technologies:

Since all business organizations have shifted their infrastructure to the cloud, a DevOps engineer must know how to set up and manage the cloud-based infrastructure that is important for building, testing, and deploying a product/application. 

You often use cloud vendors such as Google Cloud Platform, Microsoft Azure, and Amazon Web Services, etc.

  • Containerization and orchestration:

These skills come in handy during the operation stages. These include efficient releasing and deploying applications as a package. To enable these tasks, various container orchestration tools are used such as Docker & Kubernetes, OpenShift, etc. 

These tools can automate the process of scaling, configuring, provisioning, load-balancing, securing, and allocating resources in a highly-available environment.

  • Monitoring and logging:

You monitor systems to look for bottlenecks in them and take proactive steps to remove them. In this way, you can analyze systems in a better way and take measures to prevent such issues in the future.

By analyzing the recorded events, logs, and data regarding a system, you can monitor and troubleshoot systems to understand system behavior and run a suitable diagnosis accordingly.

  • Configuration management:

Configuration management tools are used to automate, design, manage and monitor various tasks that are otherwise performed manually. By making use of these tools, consistency is ensured in systems and it, therefore, increases team productivity.

Some of the popular configuration management tools include Chef and Puppet.

  • Version-controlled systems:

Oftentimes, the development team has to make changes in the current code for various operations such as application updation, product improvement or even launching a new product. Therefore, it is important to keep track of all the codes in one place.

A version-controlled tool such as Git is an excellent open-source storehouse of codes. You can always go back to the previous codes to get the bigger picture of what’s happening.

  • Continuous Integration and Deployment (CI/CD):

CI and CD are the most common phrases to hear in a DevOps environment. These are the best practices to ensure the efficient functioning of products and applications. The continuous integration includes the building and testing of codes in a single repository where all code changes are saved.

Continuous delivery refers to the operation tasks such as releasing and deploying the code changes that have been made by the software development team. This ensures enhanced collaboration, reduced workload, and better consistency of processes.

Highlighting the required soft skills as a DevOps engineer:

The following are the soft skills required as a DevOps engineer:

Working with cross-functional teams is the major duty of a DevOps engineer. It is essential to maintain effective communication and collaboration between software development and IT operations teams. You also need to communicate effectively with the stakeholders.

Projecting leadership qualities and teamwork are the most in-demand soft skills for a DevOps engineer.

  • Communication and documentation:

It can become unhandy to memorize all the codes, logs, data and events as a DevOps engineer. It is important to document all changes in one place for a DevOps engineer. Analyzing the data and keeping track of all events by documenting them is an excellent skill for a DevOps engineer to succeed.

  • Problem-solving and troubleshooting:

There could be existing bottlenecks and discrepancies between the software development and operations teams. This is where a DevOps engineer plays his vital role in resolving issues between the teams and troubleshooting existing errors in the code/operations. 

These problems could be bugs in code or unstabilized servers.

  • Adaptability and flexibility:

DevOps is a modern technology that requires constant learning and upskilling. As a DevOps engineer, you must be committed to adapting to the usage of upcoming and novel CI/CD, automation, and version-control tools. You must also be flexible in a way that you’re ever ready to solve problems between cross-functional teams.

  • Time Management and prioritization:

DevOps engineers often have to deal with multiple projects at a time that involves continuous integration, checking for code errors, troubleshooting systems, deploying software updates, etc. Therefore, they need to be agile to work in an efficient way to meet strict deadlines.

They must be able to differentiate between urgent and generic day-to-day tasks.
