When it comes to building and configuring IT infrastructure, especially across dozens or even thousands of servers, developers need tools that automate and streamline this process. Enter Puppet. Released in 2005, Puppet is one of the leading DevOps tools for automating delivery and operation of software “no matter where it runs.” In our new course, Getting Started with Puppet, we’ll show you how to bring these benefits to your networks with hands-on exercises every step of the way.
What is Puppet and what can it do for you?
Imagine that you have an IT environment with multiple application servers but you need to be able to develop and deploy quickly. Perhaps you have slightly different configurations on servers that are supposed to be identical, or you have to frequently add servers to your environment. In these scenarios, a manual approach just won’t cut it.
With Puppet’s automation, new applications and changes can be released simultaneously and with no downtime.You’ll no longer have to figure out why something works on one server but doesn’t work on another one because Puppet will configure them in the same way. You’ll also have less downtime because there is less that can go wrong when everything is configured the way it’s supposed to be. Provisioning servers is a breeze when Puppet already knows how to configure them.
This makes Puppet, available in open source and enterprise versions, a top DevOps tool, according to RightScale’s State of the Cloud Report 2017. Research firm IDC recently recognized Puppet as one of four innovators as profiled in its 2017 DevOps Infrastructure Automation report.
“Puppet has a declarative programming language and an open source-based platform to help enterprise IT and DevOps teams with common machine-readable language across mainframes.”
5 ways Puppet will make a developer’s life easier
1. It brings consistency to your servers.
With Puppet, you no longer have to figure out why something works on one server but doesn’t work on another one that is supposed to be identical.
2. It’s reliable.
When everything is configured the way it’s supposed to be, there is less that can go wrong. And that means less downtime.
3. Faster time to deployment.
Once you automate your deployment process, then you can roll out new versions of your software with the push of a button. If there is a problem with the new version of software that you just rolled out, then you can easily revert back to the previous version.
4. It’s easy to add more servers.
Because an automated infrastructure is scalable, you can easily add more servers.
5. More time to focus on what you love to do.
Because Puppet is automated, you’re freed up from the drudgery of repetitive tasks and you’ll have more time to focus on productive work.
What you will learn in Getting Started with Puppet
Our course is designed to give you hands-on experience using Puppet. We will start by installing Puppet on a virtual machine on your own desktop, and you will use it as a test environment to learn how to write Puppet code to automate server configuration. Don’t worry—we’ll guide you through every step.
You will also learn:
- How to use pre-built Puppet modules
- How to create your own Puppet modules
- How to use manifests, classes, resources, facts, nodes, and templates
- How to build a complex Puppet module using conditional statements, operators, and facts about your infrastructure
- and more!
