Overview
NAT Gateway (NG) serves as a cloud-based network service facilitating IP address translation, thereby ensuring efficient Internet connectivity for Cloud-based resources. NG enhances the security of Internet access for these resources by safeguarding private network information from exposure. It boasts the capability to manage significant volumes of Internet access requests, supporting up to 10 million concurrent connections. Additionally, NG provides IP-level traffic control, enabling real-time monitoring of traffic data to promptly identify exceptions and streamline network troubleshooting processes.
Benefits
Support for Massive Volumes of Concurrent Requests
NG provides robust support for handling large volumes of concurrent requests, accommodating up to 10 million simultaneous connections. This capability renders it particularly well-suited for applications with substantial Internet traffic demands, including video services, Internet of Things applications, and big data analytics.
High-performance Access
For enterprises necessitating frequent Internet access and substantial bandwidth demands, NG offers forwarding capabilities exceeding 5 Gbps while supporting the binding of 10 elastic IPs concurrently. This facilitates seamless management of peak traffic and ensures the robustness of large-scale Internet applications’ service delivery.
Visual Management
NG incorporates traffic management, visual representation of gateway performance statuses, multi-dimensional monitoring, and sophisticated fault alerting mechanisms, facilitating prompt identification and resolution of issues as they emerge.
Stability and High Availability
The foundational layer of NG is built with a robust design that incorporates dual-server hot backup and automated disaster recovery, guaranteeing a service availability of up to 99.99% and ensuring the steady functioning of your business operations.
Better Cost-effectiveness
Cloud offers a diverse range of on-demand NAT gateways, enabling users to select the most suitable services tailored to their business requirements. Moreover, NG supports Bandwidth Package (BWP) for a versatile and customizable experience, aiding in cost reduction for your business operations.
Service Integration
NG is capable of seamless integration with various Cloud services like Anti-DDoS Advanced and BWP, enabling the construction of a comprehensive end-to-end cloud network solution.
Features
SNAT
Source Network Address Translation (SNAT) enables multiple CVMs within a VPC to access the Internet concurrently using a shared public IP address.
DNAT
Destination Network Address Translation (DNAT) is employed to translate the private IP address, protocol, and port of a CVM within a VPC to a corresponding public IP address, protocol, and port. This enables accessibility to the services hosted on the CVM from the Internet.
Gateway Traffic Control
NG’s gateway traffic control feature offers monitoring and management capabilities at the level of IP gateways, allowing for detailed visualization of gateway traffic and straightforward insights into traffic patterns. Moreover, NG’s speed limiting functionality assists in effectively managing and blocking traffic exceptions.
Traffic Alarms
Users have the option to establish customized traffic alerts to proactively detect potential risks. These alarms trigger automated email and SMS notifications when specific metrics surpass predetermined thresholds. Monitoring and alarm functionalities are provided at no cost, facilitating prompt identification and resolution of issues as they arise.
Bandwidth Package (BWP)
NG can be utilized in conjunction with BWP to enable multiple IPs to collectively utilize the public bandwidth, ensuring that various applications have access to the required bandwidth during different peak periods and thereby effectively minimizing bandwidth expenses.
Security and Anti-DDoS Protection
Anti-DDoS Advanced delivers DDoS and CC protection with exceptionally high bandwidth, boasting top-tier BGP protection bandwidth of up to 310 Gbps. Enhanced security can be achieved by associating high-defense packets with the NAT gateway requiring protection.
Scenarios
Massive Volumes of Internet Access Requests
Secure Access to the Internet
NG offers connection services capable of handling substantial volumes of concurrent requests, accommodating up to 10 million simultaneous connections and 10 elastic IPs. With a service availability of up to 99.99%, NG is particularly well-suited for services experiencing high request and connection loads, such as web crawlers.
The SNAT feature of NG enables secure address translation for proactive Internet connectivity by the CVM, thereby mitigating potential network security vulnerabilities stemming from the direct exposure of the CVM’s public IP address to the Internet. Additionally, to uphold cloud resource security, NG can restrict external services from initiating connections with the CVM.
