For example, a full high-definition video with a resolution of two million pixels per frame is often referred to as 1080P. Similarly, 4K means 8 million pixels per frame while 8K means 33 million pixels per frame. In other words, the resolution of an 8K video is 16 times that of 1080P!
8K video, when integrated with video technologies such as 120 fps frame rate, high dynamic range (HDR), and wide color gamut (WCG) range, can appear realistic to the human eye.
To ensure smooth 8K streaming, Alibaba Cloud has launched Bare Metal Instance (X-Dragon) for high performance computing on the streaming server and in the livestream center.
Bare Metal Instance (X-Dragon) supports 96 cores and a maximum of 768 GB memory, which ensures smoothness and good experience as a streaming server. The X-Dragon Cloud Server carries Intel Xeon Platinum 8163 (Skylake) CPU and supports 96 vCPU, with instance computing performance 50% above the industry level. It adopts DDR4 memory to realize a memory data transmission rate up to 2666 MT/s and a memory bandwidth up to 128 GiB/s, satisfying the bandwidth requirement (72 Gbps) of 8K original materials and ensuring smooth watching experience. In addition, the X-Dragon Cloud Server supports up to 32 elastic network cards (ENIs) for establishment of highly available clusters, low-cost failover, refined network management, and so on, and supports high performance network of up to 4.5 million PPS, meeting the network performance requirements for key applications and eliminating packet loss at the source.
