Finally, DevOps provides a platform for automating many tedious and error-prone tasks, which can free up resources for more strategic work.
How to learn DevOps: crucial areas to upskill
In order to upskill into a DevOps role, it is important to focus on several key areas. Below we detail some of the most crucial areas to focus on when learning DevOps:
1) Configuration Management: As a DevOps engineer, you will be responsible for managing and regulating configurations. This includes maintaining consistent configurations across environments, tracking changes, and ensuring that all configurations are compliant with company policy. Configuration management is a critical part of any DevOps engineer’s toolkit.
2) Continuous Integration/Continuous Delivery (CI/CD): A key component of DevOps is automating the software development and delivery process. This means setting up continuous integration (CI) and continuous delivery (CD) pipelines to automate repetitive tasks and optimize the release process. As a DevOps engineer, you should have a strong understanding of CI/CD concepts and how to implement them using popular tools such as Jenkins, Bamboo, or TeamCity.
3) Cloud Computing: Cloud computing is another crucial area for DevOps engineers. In order to be successful in this role, you should have a good understanding of cloud architecture and how to deploy applications in a cloud environment. Many companies are moving towards a hybrid or multi-cloud approach, so it’s also important to be familiar with multiple cloud providers such as AWS, Azure, or Google Cloud Platform.
4) Monitoring & Logging: Another important area for DevOps engineers is monitoring and logging. In
Linux OS administration
When it comes to operating system administration, Linux is a clear leader in the DevOps world. That’s because Linux is a highly reliable and scalable platform that’s well suited for running cloud-based applications. Plus, many of the most popular DevOps tools, such as Puppet and Chef, are designed to work with Linux.
If you’re not already familiar with Linux, don’t worry – it’s not hard to learn. Start by becoming familiar with the basics of the command line interface. Then, take some time to learn about common tasks like managing users and installing software packages. Once you have a good understanding of the basics, you can start exploring more advanced topics like shell scripting and system automation.
There are plenty of resources available to help you learn about Linux administration, including online tutorials, books, and courses. By taking some time to upskill in this area, you’ll be well on your way to a successful career in DevOps.
Networking is a critical component of any DevOps role. As a DevOps Engineer, you will need to be able to understand and troubleshoot networking issues. This section will cover the basics of networking so that you can upskill into a DevOps role.
The first thing to understand about networking is the OSI model. The OSI model is a seven-layer model that breaks down the different components of networking. The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has its own set of protocols that need to be followed in order for data to be transferred between two points.
The second thing to understand about networking is IP addressing. Every device on a network has a unique IP address that identifies it on the network. There are two types of IP addresses: public and private. Public IP addresses can be accessed from anywhere on the Internet, while private IP addresses can only be accessed from within the network they’re assigned to.
Finally, you need to understand routing. Routing is how data travels from one point to another on a network. There are three types of routes: direct, static, and dynamic. Direct routes are the simplest type of route and involve sending data directly from one device to another without going through any intermediary devices. Static routes are slightly more complex and involve configuring predetermined routes for data to take between devices. Dynamic routes are the most complex type of route and involve using
One interpreted language
There are a few interpreted languages that are popular among developers, but Python is by far the most common. Python is used in DevOps because it is easy to read and write, and it has a large number of libraries that can be used for various tasks. Perl and Ruby are also interpreted languages that are sometimes used in DevOps, but they are not as common as Python.
There are a number of cloud services and platforms that can be used to support DevOps practices. Some of the most popular include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Each of these platforms provides a number of tools and services that can be used to automate various aspects of the software development and delivery process.
In addition to the major public cloud providers, there are also a number of private and hybrid cloud solutions that can be used to support DevOps. Private clouds can provide greater control and security for organizations that have sensitive data or compliance requirements. Hybrid clouds allow organizations to take advantage of both public and private cloud resources, depending on their needs.
There are many tools available for version control, but Git is by far the most popular. If you’re looking to upskill into a DevOps role, it’s essential that you have a good understanding of how to use Git.
Git is a distributed version control system, which means that each developer has their own copy of the codebase on their local machine. When changes are made, they are committed to the local repository and then pushed to the central server. Other developers can then pull down these changes and merge them into their own codebase.
This model of development allows for a lot of flexibility and also makes it easy to track changes and revert back to previous versions if necessary. It’s also very important for collaboration, as it’s easy for multiple developers to work on the same codebase without overwriting each other’s changes.
If you’re not familiar with Git, there are plenty of resources available online to help you get started. Once you’ve got a handle on the basics, you’ll be well on your way to upskilling into a DevOps role.
“Monitoring and observability are critical DevOps practices that help you identify and solve problems in your software development and delivery process. By monitoring your system, you can detect issues early and prevent them from becoming bigger problems. By observing your system, you can understand how it is behaving and identify potential improvements.
There are many tools available to help with monitoring and observability. Some of the most popular are Nagios, Splunk, and New Relic. Each of these tools has its own strengths and weaknesses, so it’s important to choose the one that best fits your needs.
Nagios is a popular open source monitoring tool. It can be used to monitor servers, networks, and applications. Nagios is very customizable and can be used to monitor anything that can be monitored via SNMP or by running a script.
New Relic is a commercial Application Performance Monitoring (APM) tool. New Relic provides detailed information about the performance of your web application. It also has a wide range of integrations with other tools such as Slack, PagerDuty, etc.”
A lot of people ask me how they can upskill into a DevOps role. The short answer is that you need to have a good understanding of both development and operations in order to be successful in this field. However, there is one area in particular that you need to focus on if you want to make the transition from traditional IT to DevOps: infrastructure-as-code.
In a nutshell, infrastructure-as-code is the process of managing your infrastructure (servers, networks, etc.) using code instead of manual configuration. This allows you to automate your infrastructure management, which is a key component of DevOps.
There are many benefits to using infrastructure-as-code, including:
1) Reduced error rate: When you manage your infrastructure with code, you can avoid many of the mistakes that can occur when doing things manually.
2) Increased speed and efficiency: Automating your infrastructure management can save you a lot of time and effort.
3) Improved collaboration: Infrastructure-as-code makes it easier for team members to work together on shared resources.
4) Greater flexibility: Code can be easily changed and updated, making it easy to experiment with different configurations.
If your interested in upskilling into a DevOps role, then learning how to manage your infrastructure with code is essential. There many great resources available online that help you get started. So don’t hesitate to start learning today!
