Features

  • vCPU : Memory = 1:4
  • 2.5 GHz Intel Xeon, E5-2682 v4 (Broadwell), or E5-2680 v3 (Haswell) processors
  • The network performance of an instance matching the computing type (the more advanced the computing type, the more powerful the network performance)
  • Ideal for:
    • Enterprise-class applications of various types and sizes
    • Medium and small database systems, cache, and search clusters
    • Data analysis and computing
    • Computing clusters, and data processing depending on memory
