A PICTURE OF TWO DISTINCT SBC APPROACHES

SMART SOFTWARE AND POWERFUL PROCESSORS ELIMINATE THE NEED FOR CUSTOM HARDWARE //
// Multi-thread across multiple cores
// Use cache memory as the TCAM
// Leverage CPU AES instruction set
// Do performance jobs in the kernel
// New codecs are designed for CPU
AN SBC ARCHITECTED FOR THE CLOUD

// DMA’s into guest I/O memory space without interrupting the hypervisor or VM CPU
// Bypasses the Hypervisor / vSwitch

// Lightweight Linux Containers (LXC)
// More efficient for VNFC / Microservices
// No access to the Kernel, unlike VMs
// 20% of the function / 80% of the CPU
// Employ Graphics Processors (GPUs)
// Offload processor-intensive operations
FUTURE: MICRO SERVICES AND MANAGED CONTAINERS
