1.1.1 Video cloud and big data service layer (IaaS+PaaS)
This is a public safety video networking sharing platform and its core components, including:
1. Video cloud-IT infrastructure:
//IT infrastructure layer is an optional chapter
The construction of the video cloud center mainly uses cloud computing technology to integrate IT resources, promote interconnection, information sharing and business collaboration, and help to transform from an extensive and discrete construction model to an intensive and integrated sustainable development model, enabling Management services have changed from a separate and mutually closed mode of operation to cross-departmental and cross-regional collaborative interaction and resource sharing.
The infrastructure layer provides computing, storage, network resources and computer room facilities. The data center is built based on cloud OS technology, pooling the underlying computing, storage, and network resources, shielding resource differences while providing external services, and managing and scheduling these resource pools according to different attributes. Allocate different resources to meet business needs and satisfy HA and QoS capabilities.
The underlying infrastructure layer mainly manages the hardware resources and computing, storage and other IaaS resources required by the video cloud. Considering that video is a typical 7*24 hours streaming media forwarding encoding and video computing analysis, it is IO-intensive/memory/computing-intensive Therefore, the scheduling and management of computing resources on the cloud platform is mainly based on the granularity of physical machines to reduce the performance loss caused by computing virtualization (virtual machines).
At the same time, in terms of the underlying hardware architecture, in addition to the X86CPU architecture, this issue will use AI chip technologies such as GPU as the hardware resource pool support for the video analysis center service, and will further support the FPGA hardware resource pool in the future. The hybrid architecture can greatly improve intelligent analysis. Under the same investment scale, the efficiency of video structured analysis for servers using GPU/FPGA architecture is ten times that of CPU architecture.
