Choose a Service:
Choose a service from the SAP® BTP marketplace that you want to bind to your application.For example a Database(DB) service like PostgreSQL.
Create a Service Instance:
Create a service instance of the chosen service in your SAP® BTP space. With CF CLI we can use the command

cf create-service [service-name] trial [name-given-to-instance]
Bind the Service:
Bind the service Instance to your Application, by using the Cloud Foundry CLI or the SAP® BTP cockpit to bind the service instance manually. Also, service-binding can be done by passing service information with the Manifest.YML file.
VCAP Variable:
VCAP is an environment variable in a JSON data format that is provided to an Application when it is hosted in Cloud Foundry (SAP® BTP), this variable act as a way to share the information that the application needs to connect to the service instance.
Use the Service
Once the Service is Bound you will get the required credentials to connect to the service via VCAP environment variable. After the connection to the service, you can use the service instance. Based on the service if it is a Database, server, messaging queue, etc. the operation related to connecting and usage will be different, which needs to be handled accordingly in the application.

Choose a Deployment Method:
Decide on a deployment method using the Cloud Foundry CLI or a web-based interface such as the SAP® BTP cockpit. Application Buildpack needs to be also checked if the runtime environment which the Application need is present.

To check available buildpacks use command

cf buildpack
Create a Deployment Descriptor:
Create a deployment descriptor, such as a manifest(YAML or YML) file, that specifies the configuration for your application.
Deploy and Monitor App:
Use below CLI command to Push Application to SAP® BTP
cf push [App-Name]

Create an Account and Login:
Start by creating SAP® BTP Account if you don’t have one already. Log in to your SAP® Cloud Account, go to the SAP® BTP Console, and choose the SAP® BTP service.
Create Subaccount:
Subaccount is 1-to-1 associated with Org and Org acts like a Container for Space.
Assign Quota:
A quota is a set of limits that define the maximum amount of resources (e.g. memory, CPU, storage) consumed by an organization (Org) or a space within an Org.
Create a Space:
One Subaccount can have many spaces, it is the place where the Applications are deployed.
Create Services or Deploy Apps
Inside spaces, you have capabilities to Create Services and Deploy Apps.
