Instead of asking questions directed at Terraform vs. Kubernetes, you can instead find out all the ways that Terraform is designed and built to seamlessly incorporate and work with Kubernetes.
What is an Infrastructure as Code Tool?
The first thing that you need to know about Terraform is that it is an infrastructure as code tool. When it comes to the digital world, fluidity and flexibility are important because you should always leave room to scale. In the digital world, things can change all the time, whether that comes down to problems that arise that need troubleshooting, or simply demands that exceed capabilities. Designing software, developing applications, and launching products is no simple task.Infrastructure as code tool allows software developers to enjoy certain advantages such as continuity, ease of scalability, and lack of drift. This happens because of the way that an IaC tool allows the actual infrastructure to be interacted with. Rather than manually managing your infrastructure, you can use a IaC to build your company's unique digital infrastructure in a way that allows you to change, manage or even change it with safety and continuity.
The major advantage that IaC tools give you, is that it allows your teams to leverage their time wisely and avoid the hassle and stress of manually changing, repeating, or managing infrastructure.
What is Terraform?
Terraform is an IaC tool, created by HashiCrop that is one of the most popular IaC on the market. Some of the most attractive features of Terraform that make it so popular are that it works so well with a variety of services. Terraform has some great advantages such as being able to work with multiple cloud platforms.These include some of the biggest and most competitive cloud platforms on the market like AWS, GCP, and Kubernetes. It does this because of the many Terraform plug-ins that allow Terraform to integrate with various cloud-based platforms directly through their API. The Terraform community has written over one thousand providers. Being able to use one IaC tool for multiple cloud platforms makes Terraform a robust and competent tool for almost any team of developers.
Not only that but emphasis is placed on an easy learning curve when it comes to Terraform. Using what HashiCorp calls, Configuration for Humans, this ‘human-forward’ configuration makes manipulating and using Terraform easy and accessible. Another huge advantage to Terraform is a feature known as Terraform State. This feature allows Terraform to track various resources during their deployment periods. This is an extremely valuable tool for helping to keep information and data streamlined and easily accessed.
How Easy is it Deploy With Terraform?
One of the main selling points of Terraform is that HashiCrop has created a tool that is committed to a user-forward - or human - experience. This is reflected in their declarative language, which is a step away from procedural programing language, in that it shows you your desired end state. Not only that, but it does the work of calculating dependencies when using different resources and knows how to destroy or correct them in the right sequence.When it comes to deploying with Terraform there are five steps:
• Scope
• Author
• Initialize
• Plan
• Apply
All of these steps are designed to leverage your team's time away from tedious, manual monitoring and management. This allows your engineers and developers to actually use their time, talent, and resources in ways that aren’t just monitoring and micro-managing tedious tasks.
Not only that but Terraform also offers a tracking feature in their infrastructure through a state file. This tracking feature creates a file that becomes the source of truth across an entire environment that Terraform then uses to base all changes in infrastructure. Because this file is a source of truth in an environment, the changes that Terraform will implement will still match your given configuration.
How Much Does Terraform Cost?
Terraform uses a tier-based billing method. One of its advantages for smaller startups is that it actually has a very generous and robust free tier. This free tier comes with state management, remote operations, a private module registry, and community support.The second tier starts at $20 per user and contains everything from the free tier plus team management, sentinel policy as code, task running, policy enforcement, and bronze support. Finally, the last tier is their full package with even more features and can support enterprise-sized businesses.
