When to Choose Crossplane

• If you’re a 20-person DevOps team with a limited budget and need a cost-effective IaC solution with a comprehensive control plane, Crossplane is a good choice.
• If you’re already invested in the Kubernetes ecosystem and want to leverage its automation capabilities for IaC, Crossplane is a natural fit.
• If you prioritize automated resource management and built-in security features, Crossplane’s IaC capabilities make it a better option.
• For example, if you’re a 50-person SaaS company needing to manage a complex infrastructure with multiple providers, Crossplane’s control plane can help streamline your workflows.

When to Choose Terraform

• If you’re a large enterprise with a complex infrastructure spanning multiple providers and need extensive paid support options, Terraform is a better choice.
• If you’re already familiar with Terraform’s syntax and ecosystem, it’s likely a better option to leverage your existing knowledge and expertise.
• If you need to integrate with a wide range of providers, including lesser-known services, Terraform’s extensive library of modules makes it a better fit.
• For instance, if you’re a 100-person DevOps team with a large budget and need to manage a massive infrastructure with multiple custom providers, Terraform’s scalability and support options make it a better choice.

Real-World Use Case: IaC

Let’s consider a real-world scenario where we need to manage a complex infrastructure with multiple providers using IaC. With Crossplane, setup complexity is around 2-3 days, while ongoing maintenance burden is relatively low due to its automated resource management capabilities. The cost breakdown for 100 users/actions is approximately $0, since Crossplane is open-source. However, common gotchas include the steep learning curve and limited paid support options. In contrast, Terraform requires around 1-2 days for setup, with a moderate ongoing maintenance burden. The cost breakdown for 100 users/actions is around $100-200 per month, depending on the support options chosen. Common gotchas include the limited control plane and reliance on external tools.

Migration Considerations

If switching between Crossplane and Terraform, data export/import limitations are a significant concern, as both tools have different syntax and data models. Training time needed is around 1-2 weeks, depending on the team’s familiarity with the new tool. Hidden costs include the potential need for additional paid support options or consulting services to facilitate the migration.

FAQ

Q: What is the main difference between Crossplane and Terraform? A: The main difference is the control plane, with Crossplane offering a comprehensive control plane with automated workflows, while Terraform relies on external tools.

Q: Can I use both Crossplane and Terraform together? A: Yes, you can use both tools together, but it’s essential to carefully evaluate the integration complexity and potential overlap in functionality to avoid added maintenance burden.

Q: Which has better ROI for IaC? A: Based on a 12-month projection, Crossplane has a better ROI for small to medium-sized teams, with estimated cost savings of around 30-50% compared to Terraform. However, for larger teams with complex infrastructure needs, Terraform’s extensive paid support options and scalability may provide a better ROI in the long run.

Bottom Line: Ultimately, the choice between Crossplane and Terraform depends on your team’s specific use case, size, and budget, but if you prioritize a comprehensive control plane and don’t mind the added complexity, Crossplane might be the better choice for IaC.
