# BTP Runtime Environments

## BTP Application Runtime Environments

In SAP BTP, there are three primary places where you can run your applications:

1. **ABAP Environment**: This is where you can use a programming language called ABAP to build and run your applications. It's a traditional environment in SAP.
2. **Cloud Foundry Environment**: This environment is based on a technology called Cloud Foundry. It allows you to create and run applications using various programming languages and services in a flexible and modern way.
3. **Kyma Environment**: Kyma is another environment in SAP BTP. It provides a set of tools and services to develop and manage applications using cloud-native principles. It's designed for building scalable and resilient applications.

So, in SAP BTP, you have these three options for running your programs, and you can choose the one that best suits your needs and preferences.

## SAP BTP Kyma Environment:

* **Use Case**:
  * Geared towards building cloud-native, microservices-based applications.
  * Suitable for scenarios where flexibility and scalability are essential.
* **Programming Language**:
  * Allows developers to use various programming languages and tools.
* **Integration**:
  * Can integrate with SAP systems and external services.
  * Offers API management and event-driven architecture for seamless integration.
* **Microservices**:
  * Emphasizes a microservices architecture, enabling the development of modular and independently deployable components.
* **Serverless Capabilities**:
  * Provides serverless computing capabilities for efficient resource usage.

## SAP BTP Runtime Environment Comparison Summary:

* The ABAP Environment is best for SAP-specific applications and customization within SAP systems. It's tightly integrated but less flexible in terms of technology choices.
* The Cloud Foundry Environment offers flexibility in terms of programming languages and tools, making it suitable for a wide range of cloud-native applications, both SAP and non-SAP.
* The Kyma Environment is ideal for building modern, cloud-native, and scalable applications with a focus on microservices and serverless capabilities. It's also suitable for integrating with SAP systems and external services.

The choice between these environments depends on your specific use case, the need for SAP integration, and your development preferences. For SAP-centric projects, the ABAP Environment might be preferred, while Cloud Foundry and Kyma are better suited for more general cloud-native and scalable applications.
