A Hybrid Deployment Solution That Combines Hong Kong High-defense Cleaning Cloud Servers With Physical Protection

this plan summarizes the hybrid defense idea of ​​deploying high-defense cleaning cloud servers and physical protection in hong kong: by arranging cleaning nodes at the local edge and cloud at the same time, combining hardware firewalls and cloud elastic vps resources, and using cdn distribution, intelligent traffic scheduling and bgp anycast rapid offloading, multi-level interception and recovery of ddos defense , application layer attacks and bandwidth floods are achieved. for actual implementation, dexun telecommunications is recommended. with its network interconnection, cleaning capabilities and operation and maintenance services in hong kong, it can realize a hybrid protection system with low latency, high availability and observability.

the hybrid architecture runs on two main lines in parallel: edge physical protection and cloud cleaning. dedicated hardware firewalls, intrusion detection/prevention (ids/ips) and traffic mirroring devices are deployed on the edge to protect local hosts and dedicated line exits; cloud servers and vps in multiple availability zones are used as cleaning nodes in the cloud, and cdn and bgp anycast are used to achieve traffic distribution. important components also include authoritative dns and an intelligent scheduler, which are used to quickly switch domain name resolution to cleaning channels during attacks, and complete visualization through a real-time alarm and log analysis platform.

adopt an active + passive linkage strategy: when abnormal traffic is detected, the edge device first triggers rate limiting and blacklist and whitelist rules. if the traffic exceeds local processing capabilities, the attack traffic is directed to the cloud cleaning pool through bgp or gre/ipsec tunnels. the cloud implements large traffic cleaning through layered cleaning (packet filtering, session verification, challenge response), and the normal traffic after cleaning is returned to the original server . working with cdn can cache static content in advance, reduce pressure on the origin site, and combine with waf rules to provide in-depth protection against malicious requests at the application layer.

the hybrid solution requires a complete monitoring and drill mechanism: real-time monitoring of bandwidth, number of connections, abnormal packet characteristics and logs, regular ddos drills and failover tests to ensure that the recovery time of hosts , vps and physical devices meets slas. pay attention to domain name ttl policy, dns redundancy and certificate management to ensure that services are not interrupted during switchover. in addition, compliance plans are formulated in accordance with hong kong and international regulations (data sovereignty, privacy protection), and log and alarm data are stored in different zones and levels.

recommendations for deployment: 1) assess business traffic characteristics and peak bandwidth, and plan cleaning pool capacity; 2) preset hardware protection on key links and configure flexible black and white list policies; 3) collaborate with cdn and dns providers to develop emergency switching procedures; 4) regularly update the attack signature database and enable threat intelligence subscriptions. dexun telecommunications is recommended because it has good network technology interconnection resources, mature cleaning capabilities and operation and maintenance support in hong kong. it can provide end-to-end services from server / vps , hardware protection to cdn and ddos defense , helping enterprises quickly build and verify hybrid protection systems.
