PRODUCT OVERVIEW
What is Hong Kong DDoS-protected server?
- Hong Kong deployment
- Cross-border connections
- DDoS protection
Hong Kong DDoS-protected servers focus on Hong Kong’s deployment region and network attack protection. Combined with user distribution, operator lines and business protocols, the access experience, server resources and DDoS-protected solutions are evaluated to support cross-border business deployment planning.
What to evaluate
The selection of Hong Kong DDoS-protected servers should be based on the user's network and business dependencies. Hong Kong can be a candidate location for regional deployment, but the actual experience is determined by the operator interconnection, forward and return routing, cleaning path and data access of the application, and needs to be verified with complete requests from representative users.
Taking into account cross-border connectivity and protection
At the same time, we examine daily access lines and attack cleaning paths to understand the impact on routing, delay and business connections after protection is triggered.
Deployment by business organization region
Hong Kong nodes can be included in the planning of websites, applications or multi-region architectures, and the deployment method can be determined by combining data synchronization, disaster recovery and access scheduling.
INSIDE THE ARCHITECTURE
Place Hong Kong within the complete network and data path
The region describes the location of the server, and the business experience also depends on how the request arrives, how it is returned, and what systems need to be accessed after calculation.
- 01
User networks
Establish samples by user region, operator and access type to identify main revenue or key collaboration groups.
- 02
Cross-network transit
Observe the forward path to the Hong Kong entrance and the return path to the user respectively, and mark the test period.
- 03
Protection and compute
Confirm the forwarding path under normal access and cleaning status, and verify the actual interface performance on the business instance.
- 04
Regional coordination
Organize the location of databases, object storage, and external services, and arrange paths for synchronization, backup, and failover.
Choose for your users, not just the network label
Users in the same city may also experience different paths due to different access operators, mobile networks or enterprise exits. Forward refers to the user to the server, and return refers to the server returning to the user. The two are not necessarily symmetrical. During evaluation, test points should be selected based on the proportion of various users, and operator and time period information should be saved. The results of one test node cannot be used to represent all visitors.
Test the service while traffic is being scrubbed
The direct path of the business during normal times may be different from the traction and forwarding paths during cleaning, and the delay and session behavior may also change. It is necessary to confirm the actual relationship between the entrance, protection node and origin server, and check the switching and recovery process with the cooperation of the service provider. The acceptance should include business accessibility in the clean state, time consumption of key interfaces and long connection reconstruction, to avoid recording only network data when idle.
Keep frequent dependencies close
If the Hong Kong application needs to access the database across regions for every request, the network round trip will enter the critical path of the interface. Before deployment, the number of synchronous calls, data update frequency and consistency requirements should be counted, and the feasibility of nearby reading, caching or asynchronous tasks should be evaluated. Region splitting also increases synchronization and troubleshooting costs, so services should be divided by business boundaries to avoid splitting dependencies solely by server location.
The information on this page is used to explain general regional deployment methods and does not mean that WAF.PRO has committed to specific computer rooms, hardware, CN2 or triple network lines; the applicable scope should be confirmed through actual delivery solutions and line testing.
PERFORMANCE & CAPACITY
Use metrics to locate the bottleneck
Specify samples and observation windows first, then compare plans. The median illustrates the normal state, and the tail delay, failure rate, and peak period changes determine whether the user can stably complete the operation.
| Metric | Application impact | How to assess |
|---|---|---|
| Access user distribution | Experience may vary across carriers and regions. | Covers fixed, mobile and enterprise networks based on the proportion of real users. |
| Round-trip path and RTT | Detours, congestion, and routing changes can affect round-trip performance. | Test from both controllable ends and save the route and time by direction. |
| Packet loss and retransmission | Will slow down transmission and affect interactions and ongoing sessions. | Combined with end-to-end packet loss, retransmission and application error judgment. |
| Real application timing | A smooth network does not mean that login or submission is fast enough. | Breakdown of DNS, connection establishment, TLS, first byte and complete operation time. |
| Zone dependencies and replication delays | Synchronization lag affects reads and failover. | Monitor replication backlog and verify the status of recovered data. |
Metrics and terminology
- RTT
- The round trip time required for data to travel from the test end to the target end and back does not directly represent one-way latency.
- time to first byte
- The waiting time from issuing a request to receiving the first response byte is affected by network and server-side processing and other factors.
- RTO: recovery time objective
- The acceptable target time set by the business from interruption to recovery should be verified through drills.
- RPO: recovery point objective
- Measure the data loss window that the business can tolerate in terms of time, which is used to select backup, replication and recovery strategies.
BEFORE YOU CHOOSE
Define requirements before choosing resources
Bring these four types of information to make the selection discussion more concrete.
- Users and regions
- Mainly visited countries or regions, operators, daily and peak access periods.
- Network quality
- Bidirectional latency, packet loss, jitter, backhaul path, and evening peak performance.
- Bandwidth and Protection
- Business bandwidth, defense quota, cleaning location, over-limit processing and recovery conditions.
- Resources and Deployment
- Specific resource forms, hardware specifications, system support and cross-regional data synchronization.
APPLICATION SCENARIOS
Workloads to start with
Cross-border websites and e-commerce
Provide website services to visitors from different regions, and optimize access paths by combining static resource acceleration and origin server deployment.
Asia Pacific Apps and Games
Conduct line testing based on players or users' main regions to match protocols, bandwidth and protection requirements.
Regional business node
Plan Hong Kong service nodes for multi-regional businesses and evaluate data synchronization, back-to-origin and cross-regional communications.
DEPLOYMENT PLAYBOOK
Pilot the region before planning primary and standby services
Use small-scale operations to verify the benefits of Hong Kong deployment, and gradually complete the observation, data and recovery capabilities required for cross-regional operations.
- 01
Create access sample
Summarize the main user sources, select representative operators and peak hours, and define acceptable operation time and failure rates.
- 02
Pilot the workload
Verify the website or interface with the complete request chain, while measuring uploads, downloads, and necessary long connection scenarios.
- 03
Plan data replication
Clarify the primary write location, read replicas, and backup strategies, and set rules for replication lag, duplicate commits, and conflict handling.
- 04
Test failover and failback
Practice health determination, entrance adjustment, data takeover and switchback inspection, record the actual recovery time and data differences, and check against the predetermined recovery goals.
Deployment trade-offs
Synchronous cross-region writing will increase waiting, and asynchronous replication needs to accept and manage data lag; the cost and operation and maintenance complexity of backup and recovery, warm backup and multi-active are also different, and should be selected based on business recovery goals.
OPERATE WITH CONFIDENCE
From launch to ongoing operations
Make tests reproducible
Each round of testing saves the source region, operator, protocol, target, time period and business version, and repeats sampling during working days and peak periods. Bidirectional measurements should be recorded separately; the direction and hop-by-hop round trip time displayed by a single traceroute cannot be directly regarded as a complete bidirectional link conclusion.
Interpret routing alongside endpoint behavior
Intermediate routers may limit or reduce the priority of probe replies. Failure of a certain hop to respond does not necessarily mean service packet loss. The investigation should check the endpoint connection, transmission and application data, and compare the routing changes before and after the exception; if operator assistance is required, evidence of the same time period should be provided.
Base failover on application health
Only checking port liveness may miss database or external dependency failures. Health signals that reflect key services should be selected, observation windows and anti-shake conditions should be set, standby site capacity and data progress should be checked before switching, and user sessions, callbacks, and repeated execution risks should be checked after recovery.
Include data in regional operations
Clearly record the storage locations of business data, logs, backups, and keys, limit operation and maintenance access, and maintain recovery copies. Hong Kong deployment still needs to evaluate applicable requirements based on business and data flow; replication cannot replace independent backup, and recovery after accidental deletion or data damage should also be verified.
CHOICES & TRADE-OFFS
Compare product advantages under real conditions
When your business is
Users are concentrated in Hong Kong and surrounding areas
Priority will be given to conducting real business pilot projects in this region.
Geographical proximity has reference value, but ultimately the interconnection path and application dependencies still need to be verified.
When your business is
Both mainland and overseas users account for a large proportion
Compare routes by group and evaluate multi-region services.
A single region may not be able to meet the experience goals of each operator and region at the same time.
When your business is
Hong Kong nodes are used for disaster recovery
First clarify the recovery goals, and then select the data replication method.
An accessible standby server does not equal a complete business that can take over writes.
Three judgments that are easily overlooked
Misconception: Hong Kong always gives low latency to mainland users
Specific paths cannot be guaranteed by region, and operator interconnection, congestion, and cleaning and forwarding all require actual testing.
Misconception: a CN2 label guarantees identical paths in both directions
Line labels are not enough to cover all directions and user networks. You should confirm the specific routes and applicable scope.
Misconception: two regions guarantee lossless failover
Data replication, capacity preparation, health judgment, and consistency and failback design are also required.
QUESTIONS & ANSWERS
Questions before you choose
Is access to Hong Kong servers faster from everywhere?+
Not necessarily. Access experience depends on user location, operator, circuit, backhaul routing and network load. It is recommended to test latency, packet loss and actual business response at different time periods from major user areas.
Does the Hong Kong DDoS-protected server have to be an exclusive physical machine?+
"Hong Kong DDoS-protected" describes the region and protection direction, and cannot alone describe the resource form. When purchasing, you need to confirm whether cloud instances, bare metal or other dedicated servers are delivered, as well as the corresponding hardware and network configuration.
What business information needs to be prepared before activation?+
Please provide the main access area, business type, protocol port, normal bandwidth and existing attack situations to evaluate the line and protection. Please confirm with technical consultant for test conditions, lead time and support scope.
Can asynchronous replication ensure no data loss during switching?+
This guarantee cannot be made simply by enabling replication. Asynchronous replication may lag. In the event of a failure, you should confirm what data has been received by the standby site, and decide on the takeover and compensation method based on the allowable data loss range of the business.
Why is the ping fast but the page is still slow?+
The ping reflects only part of the probe round trip; connection establishment, encrypted handshakes, resource loading, and cross-region database calls can all add to the wait.
How to compare normal path and clean path?+
Use the same set of clients and business samples under test conditions confirmed by the server to compare bidirectional paths, tail delays, failure rates, and session recovery.
