Popular DevOps Tools of 2021
DevOps has become a crucial part of the world of software. If you’re looking for a job as a DevOps engineer, now is the time to learn these tools. Here are some popular tools that will be around in 2021 and how they can be used to develop and deploy software.
Ansible Tool
Another open-source tool that’s worth looking into is Ansible which will generally be used as an orchestration language across your entire infrastructure rather than just running locally on your computer as Chef does. It works by describing how groups of machines should look and then performing tasks on them. It’s important to know the differences between docker vs ansible so you can choose one or the other. You can either run Ansible in an agentless mode where it connects directly to the nodes you want to manage or with an agent that’s installed on each node so that you can use Ansible for remote command execution instead of just configuration management.
Docker Tool
Another DevOps tool that is extremely popular these days is Docker, which will probably replace virtual machines as the primary way of running isolated applications on one host. With Docker, you use containers instead of virtual machines to launch specific applications in an isolated environment where they have network access but no disk read/write permissions by default. You can then use another DevOps tool like Kubernetes or Mesos to manage your containers across multiple servers and configure them so that they run side-by-side if necessary instead of launching several copies of an application on a single machine. These tools aren’t mutually exclusive, so you can use all of them together on your next DevOps project to automate the entire application lifecycle.
Chef Tool
One tool that has made life much easier for both developers and operations teams is Chef. With Chef, you can automate your infrastructure by writing code instead of filling out forms or clicking through menus on an administrative interface. You write recipes using Ruby syntax, which describes how individual nodes should look. These recipes are then tested locally before being pushed to production servers where they automatically configure various pieces of your infrastructure from load balancers to web servers. In addition to securing all of the dependencies, you can also repeat your recipes any time new servers are added or removed from production.
Chef is easy to master because it’s just a tool that runs locally on your computer. You don’t have to learn anything about cloud infrastructure to get started with Chef and most DevOps engineers agree that they would rather automate their infrastructure than manually configure each server in a cluster. Chef has an extremely simple interface and will allow you to test out configuration management and see how it works before taking on more complex tools like Puppet or Ansible.
Puppet Tool
One effective way of configuring servers is by using the open-source tool Puppet. It lets you define what you want all of your nodes to look like so that you can launch servers that are identical to one another. To get started, you’ll need to install Puppet on each server and configure it using a master-client model. Puppet is used for more than just launching servers, though. You can also use it for managing users and making sure there aren’t too many or too few of them. The best part about Puppet is the fact that you don’t have to manage nodes individually because everything happens from a central location.
Jenkins Tool
A DevOps tool that is often used for continuous integration and delivery is Jenkins. This lets you automate the software development process by calling different scripts at certain stages of your project’s development. For instance, if you’re building a code library named lib, you could configure Jenkins to launch “tests” when someone commits changes to the master branch and then notify all developers in an email when tests fail because their changes break existing functionality in some way. Automating your build process can help you avoid releasing a faulty version of your software and gives developers the ability to push their changes live much faster.
Vagrant Tool
Finally, a DevOps tool that you’ll want to master is Vagrant. You can use this tool to launch virtual machines on your local computer so that they run the same operating system as they would in production. It’s similar to Docker except for the fact that it allows users to access the file system of their development environment. This is an excellent way of learning more about your production environment without launching servers or building images yourself – just configure them with Vagrant and then install whatever software you need on them by hand.
What You Should Consider Before Choosing Any Of These Tools
Before you start learning how to use any of these DevOps tools, consider the pros and cons involved. For instance, if you’re worried about security, it might not be a good idea to learn Jenkins because this tool regularly runs as an unprivileged user without much fine-grained access control and allows users to configure their SSH keys inside of Jenkins jobs. You’ll also need to make sure that your organization supports all of the different languages and techniques used by each tool before choosing them for your next project.
Some projects might benefit from using virtual machines because they help protect code from software dependencies that aren’t required in production. On the other hand, some applications like web servers or Docker containers can run anywhere which makes them perfect for testing purposes because they don’t require much configuration.
Another thing to keep in mind is that some of these tools might not be a good choice for you if you’re just getting started with DevOps and your company doesn’t have a lot of infrastructure or development experience. It could take months to get the most out of Docker, Kubernetes, Jenkins, and Vagrant after all – so be sure to prioritize learning how to use them properly before starting any major DevOps projects at your office.
As you can see, there are plenty of popular DevOps tools out there right now that will allow you to automate every aspect of your application lifecycle. Masters of this trade may be few and far between, but there are plenty of people out there who have just begun learning the ins and outs of DevOps tools like Chef or Puppet. If you’re ready to take that next step in your career, it’s probably time for you to pick up some new skills with these popular DevOps tools!
