Terraform vs Yocto: What are the differences?
Developers describe Terraform as "Describe your complete infrastructure as code and build resources across providers". With Terraform, you describe your complete infrastructure as code, even as it spans multiple service providers. Your servers may come from AWS, your DNS may come from CloudFlare, and your database may come from Heroku. Terraform will build all these resources across all these providers in parallel. On the other hand, Yocto is detailed as "An open Source embedded Linux build system". It is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture. It provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations, and best practices that can be used to create tailored Linux images for embedded and IOT devices, or anywhere a customized Linux OS is needed.
Terraform and Yocto can be categorized as "Infrastructure Build" tools.
Some of the features offered by Terraform are:
- Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
- Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.
- Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
On the other hand, Yocto provides the following key features:
- Open source embedded Linux build system
- package metadata
- SDK generator
Terraform is an open source tool with 18.2K GitHub stars and 4.92K GitHub forks. Here's a link to Terraform's open source repository on GitHub.
Uber Technologies, Instacart, and Slack are some of the popular companies that use Terraform, whereas Yocto is used by Dronesmith Technologies, Koolicar, and Ubidreams. Terraform has a broader approval, being mentioned in 667 company stacks & 1273 developers stacks; compared to Yocto, which is listed in 6 company stacks and 4 developer stacks.
