Features

    • Source Network Address Translation

    NAT Gateway with SNAT function provides proxy service of Internet access for ECS without public network IP in VPC.

    • Destination Network Address Translation

    NAT Gateway supports DNAT function, which maps the public network IP on NAT Gateway to ECS with Internet service. DNAT also supports port mapping.

    • Shared Bandwidth

    Multiple IP addresses shared with public network bandwidth reduces bandwidth cost for services during peak traffic.

Applications

  • Multiple Hosts Internet Access
  • Shared Bandwidth

Description

ECS can implement the Internet function through a public network IP on the SNAT gateway in a VPC, ensuring that ECS won't be exposed to the public network.

Multiple Hosts Internet Access

Description

ECS instances are created in VPCs for applications to deliver services to the Internet. Network traffic on these applications doesn’t share the same peak hour. To minimize the influence of network traffic fluctuations and to reduce the bandwidth costs, you can allow multiple IP addresses to share the same bandwidth.
