gRPC stands for Google Remote Procedure Call. The protocol was developed in Google's labs and takes into account the increasing trend of fragmenting applications into microservices when they are operated in the cloud. The resulting avalanche of function calls between microservices requires a high degree of efficiency. gRPC takes this into account with its HTTP/2-based protocol stack. In addition, gRPC abstracts from the programming language so that calls between microservices programmed in different languages are also possible. The protobuf data format developed by Google specifically for this purpose allows the language-neutral setup of remote procedure calls and the transferred variables.</p
gRPC has also established itself as a quasi-standard in model-based streaming telemetry. This involves a permanent stream of telemetry data emanating from a network element, which places the highest demands on the performance of the transmission protocol. With its architecture trimmed for efficiency, gRPC is predestined for this task and is already offered as a feature by many well-known manufacturers.

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.

Online training
- You wish to attend a course in online mode? We offer you online course dates for this course topic. To attend these seminars, you need to have a PC with Internet access (minimum data rate 1Mbps), a headset when working via VoIP and optionally a camera. For further information and technical recommendations, please refer to.
