overview of common network and resolution issues in cross-border site groups

1) dns resolution delay: international resolution links often fluctuate between 100-400ms, affecting the loading of the first screen.
2) domain name strategy: main domain + multi-country pan-resolution, it is recommended to use a resolution provider with geodns.
3) jump and sni: for multiple domain names in the site group, the certificate must be compatible with sni to avoid tls handshake failure.
4) ip attribution and ban: a large number of ips from the same as may be identified by search engines or platform risk control.
5) monitoring suggestions: deploy three types of detection: ping/http/trace, and set the thresholds to 200ms, 2s, and 20 hops respectively.

key points for server selection in korean and american site clusters

1) node selection: korean station group gives priority to seoul (nipa/kt/sktelecom), us station group gives priority to los angeles/virginia (west coast/east coast diversion).
2) bandwidth and ports: it is recommended that korean lines have at least 100mbps dedicated ports, and us site groups recommend 200mbps or more or 1gbps shared + traffic package.
3) hardware configuration: static website group page can start with 2vcpu+4gb ram, dynamic e-commerce recommends 4vcpu+8-16gb ram.
4) storage type: nvme ssd is preferred for static resources, independent hdd or object storage is recommended for logs and backup.
5) security functions: choose a supplier with bgp anycast, cleaning capabilities ≥10gbps, and support waf and rate limiting.

3.

practical suggestions on cdn and caching strategies

1) cdn coverage: deploy global anycast cdn and set up edge nodes in south korea and the united states. the recommended ttl for static resource caching is 1 day to 7 days.
2) dynamic acceleration: use intelligent routing or tcp acceleration for api/shopping cart to avoid excessive rtt for one-way across the ocean.
3) cache layering: three-layer settings of browser cache, cdn edge, and origin cache, and reasonable allocation of cache-control.
4) cache preheating: use the batch preheating api to push key pages when going online to reduce sudden traffic back to the source.
5) certificate management: use let's encrypt or commercial certificates uniformly and enable ocsp stapling to reduce tls delays.

4.

ddos defense and high availability design

1) protection capacity: according to case estimates, the peak bandwidth of class a cross-border station groups is usually 200-800mbps, and it is recommended that the cleaning capability is ≥2-5x the peak value.
2) multi-layer defense: edge cdn cleaning + cloud cleaning + three layers of local firewall, enabling rate limiting, connection restrictions and geo-blocking.
3) automatic elasticity: activate automatic expansion and traffic redirection strategies with cdn/protection vendors.
4) real-time alarm: l7 traffic anomalies and the source site return rate increase by ≥20% trigger an alarm and automatically switch backup nodes.
5) drills and filings: regularly drill ddos response plans, prepare backup as/standby bgp links and complete filing information.

case: the practice of a cross-border e-commerce company a in south korea and the united states

1) background: company a focuses on the japanese, korean and north american markets, with an average monthly visit volume of 500,000 uvs, and a peak single-day promotional pv of 2.5 million.
2) architecture: 2 hosts in seoul, south korea + 3 hosts on the east coast of the united states. the front end uses global cdn + local cache nodes.
3) configuration example: see the table below (the table has a border width of 1 and is centered, and the text is centered).
4) protection: enable waf, anycast cdn, ddos cleaning pool 10gbps, and the average peak cleaning delay is <200ms.
5) effect: after deployment, the average first screen loading time dropped from 2.6s to 1.1s, and the return traffic dropped by approximately 68%.
node specification bandwidth storage ddos cleaning
seoul, south korea 4 vcpu / 8 gb ram 200 mbps exclusive 80gb nvme clean pool 5 gbps
virginia, usa 8 vcpu / 16 gb ram 1 gbps shared + traffic package 200gbnvme clean pool 10 gbps

practical suggestions and cost estimates for leasing, operation and maintenance

1) key points of the contract: clarify the ip pool ownership, bandwidth baseline, ddos cleaning sla and billing method (based on peak value or traffic volume).
2) price reference: korean vps monthly payment is about $30-120 (different specifications), and the monthly cost of 1gbps hosting bandwidth in the united states starts at $200.
3) operation and maintenance tools: use prometheus+grafana monitoring, and elk stack for centralized log analysis.
4) automation: scripted deployment and backup, using iac (terraform/ansible) to manage multi-node clusters.
5) compliance and filing: check the target country domain name and icp/local compliance to avoid node being blocked due to filing issues.
