Dedicated General-Purpose ECSs

Overview

Dedicated general-purpose ECSs provide dedicated vCPUs, featuring powerful performance. In addition, the ECSs use latest-generation network acceleration engines and DPDK to provide high network performance, meeting requirements in different scenarios.

  • C6 ECSs use second-generation Intel® Xeon® Scalable processors to provide powerful and stable computing performance. By using 25GE high-speed intelligent NICs, C6 ECSs offer ultra-high network bandwidth and packets per second (PPS).
  • C3 ECSs deliver powerful and stable computing performance. They use Intel® Xeon® Scalable processors and high-performance NICs to provide high performance and stability for enterprise-grade application requirements.
  • CC3 ECSs provide balanced computing, memory, and network performance. They are suited for distributed computing clusters and applications with moderate loads, such as websites and web applications, generalized databases and cache servers, enterprise applications, and data analysis.

Scenarios

  • C6 ECSs: Websites and web applications, generalized databases and cache servers, and medium- and heavy-workload enterprise applications with strict requirements on computing and network performance
  • C3 ECSs: Small- and medium-scale databases, cache servers, and search clusters with high requirements on stability; enterprise-grade applications
  • CC3 ECSs: Small- and medium-scale e-commerce websites, SQL databases, computing clusters, and backend servers for enterprise applications
