hfc6, compute optimized instance family with high clock speed

Features
  • Provides predictable stable and high performance and reduces virtualization overheads with the use of the ECS Bare Metal Instance architecture.
  • I/O optimized.
  • Supports enhanced SSDs, standard SSDs, and ultra disks.
  • Provides strong storage I/O performance proportional to computing capacity.
