Improving Orchestration Service Using gRPC API and P4-Enabled SDN Switch in Cloud Computing Platform: An OpenStack Case.

Cloud computing platforms like OpenStack use orchestration as a crucial component in the deployment and administration of cloud services. For the deployment and management of virtualized resources, these platforms mainly rely on orchestration techniques. Cloud orchestration services like Service Function Chaining (SFC) have benefited from lower costs and increased scalability for cloud computing platforms thanks to the introduction of technologies like Software-Defined Networking (SDN) and Network Function Virtualization (NFV). The use of gRPC APIs and an SDN switch with P4 support is described in this research as an innovative method for enhancing SFC orchestration service in OpenStack computing platforms. The proposed approach uses a P4 enabled SDN switch and gRPC APIs to enhance network performance in data plane communication with the underlying infrastructure and performance in terms of service creation time between the SFC orchestration services. Our evaluation's findings demonstrate that this strategy greatly boosts the orchestration service's performance, making it more appropriate for usage in extensive cloud-based deployments. Additionally, the possibility of combining gRPC APIs and P4 switch to improve the efficiency and flexibility of orchestration service in cloud computing platforms is demonstrated by the performance analysis of the proposed approach on numerous platforms across diverse use cases.
