# Service Invocation
|
|
|
|
Dapr-enabled apps can communicate with each other through well-known endpoints in the form of http or gRPC messages.
|
|
|
|
|
|
|
|
|
|
1. Service A makes a http/gRPC call meant for Service B. The call goes to the local Dapr sidecar.
|
|
2. Dapr discovers Service B's location and forwards the message to Service B's Dapr sidecar
|
|
3. Service B's Dapr sidecar forwards the request to Service B. Service B performs its corresponding business logic.
|
|
4. Service B sends a response for Service A. The response goes to Service B's sidecar.
|
|
5. Dapr forwards the response to Service A's Dapr sidecar.
|
|
6. Service A receives the response.
