Cloud Foundry vs Terraform: What are the differences?

Introduction

In this article, we will discuss the key differences between Cloud Foundry and Terraform.

1. Deployment Platform: Cloud Foundry is a platform-as-a-service (PaaS) solution that provides a ready-to-use runtime environment for applications. It abstracts away the underlying infrastructure and provides a way to easily deploy, manage, and scale applications. On the other hand, Terraform is an infrastructure-as-code (IaC) tool that allows users to define and manage their infrastructure as code, making it more flexible and agnostic to any cloud provider or infrastructure platform.

2. Abstraction Level: Cloud Foundry focuses on the application layer, abstracting away the underlying infrastructure details. It provides developers with a high-level interface to deploy and manage applications without worrying about the infrastructure setup. Terraform, on the other hand, operates at the infrastructure layer, providing a way to provision and manage infrastructure resources like virtual machines, storage, networking, etc., across different cloud providers.

3. Platform Flexibility: Cloud Foundry is a specific platform that offers a predefined runtime environment, buildpacks, and services. It has its own ecosystem, and applications need to be developed and designed to run on Cloud Foundry. In contrast, Terraform is highly flexible and vendor-agnostic. It can be used to provision and manage resources across multiple cloud providers and infrastructure platforms without being tied to any specific platform or runtime environment.

4. Infrastructure Orchestration vs Application Orchestration: Terraform is primarily an infrastructure orchestration tool. It focuses on provisioning and managing the infrastructure components required by an application to run. It defines and manages the infrastructure's desired state, making it possible to manage updates and changes over time. Cloud Foundry, on the other hand, is an application orchestrator. It focuses on deploying, scaling, and managing applications, but it does not directly manage the underlying infrastructure.

5. Deployment Flexibility: With Terraform, deployments are more granular and customizable. Users can define and manage individual infrastructure components, making it possible to create complex and customized infrastructure setups. In Cloud Foundry, deployments are higher-level and follow the platform's predefined structure. It provides a simplified deployment model, suitable for quickly deploying and managing applications without complex infrastructure configurations.

6. Community and Ecosystem: Cloud Foundry has an established community and ecosystem. It provides a wide range of buildpacks, services, and tools that integrate well with the platform, making it easier to develop, deploy, and manage applications. Terraform, on the other hand, has a growing and active community but offers a more generic and flexible approach. It benefits from the wider infrastructure-as-code ecosystem and integrations with different providers.

In summary, Cloud Foundry is a platform-as-a-service (PaaS) solution that focuses on the application layer, providing a simplified deployment model and an ecosystem of buildpacks and services. Terraform, on the other hand, is an infrastructure-as-code (IaC) tool that operates at the infrastructure layer, providing a flexible and vendor-agnostic approach to provision and manage infrastructure resources.
