BizFly Cloud is Vietnam's one-stop cloud service platform, part of the VCCorp Group, dedicated to providing comprehensive cloud infrastructure and cloud-native services for enterprises, large-scale online businesses, and developers.
Within the local network environment in Vietnam,BizFly Cloud CDN (commonly referred to as vCDN or CDN Service) is positioned as one of its core products.Accelerate the delivery of static and dynamic content on user websites, enhance user access experience, and provide fundamental security protection capabilities.。
Unlike typical global CDN providers, BizFly Cloud's CDN service is more focused on Southeast Asia / Vietnam Regional Access Optimization。
This is clearly reflected in its node layout, product design, and pricing structure. Given the pronounced regional characteristics of local market demand, BizFly Cloud holds certain advantages in terms of connectivity with local ISPs and optimized access strategies within Vietnam.
At the same time, it leverages BizFly Cloud's comprehensive cloud ecosystem, integrating seamlessly with products such as load balancers, cloud firewalls, and security groups. This makes it ideal for users already running operations on the BizFly Cloud platform to scale their services.
This evaluation will comprehensively analyze based on real-world access and business loading scenarios.BizFly Cloud CDNPerformance in terms of access acceleration, stability, resistance to attacks, cache hit rates, and user experience, combined with objective evaluations based on actual test data.

I. Why Choose BizFly CloudCDN for Evaluation
BizFly Cloud is a rapidly growing cloud service provider in the Vietnamese market. Its CDN service features distinct localized optimization capabilities, particularly earning market recognition for accelerated access and enhanced network stability across Southeast Asia.
The core purpose of this evaluation is not simply to determine whether it is “the world's fastest CDN,” but to answer the following practical questions:
Can integrating CDN into the BizFly Cloud ecosystem significantly improve access performance? How does it perform in terms of protection and stability under moderate DDoS attack conditions?
Our testing is based on real-world business integration, covering the entire process from onboarding and configuration to performance testing and attack protection, providing a comprehensive analysis to avoid empty parameter listings.
II. Test Environment and Actual Access
| Project | Explanation |
|---|---|
| Testing Party | The Cybersecurity and Performance Team |
| Business Type | Static resources + API |
| Origin server location | Ho Chi Minh City / Singapore VPS |
| Access Method | BizFly CloudCDN+ CNAME |
| Testing Cycle | Lasting for 7 days |
The BizFly CloudCDN console setup process is highly intuitive. After completing custom domain, SSL configuration, and caching rules, changes take effect immediately without requiring code modifications.
III. Packages and Billing Methods
BizFly CloudCDN's billing model resembles the common “prepaid + pay-as-you-go” approach but offers greater flexibility, allowing dynamic adjustments based on actual business traffic patterns.
| Project | Explanation |
|---|---|
| Billing Method | Pay-as-you-go CDN billing + Prepaid plans |
| minimum charge | No prepayment restrictions |
| SSL Support | Supports custom certificates or automatic issuance |
| Multi-domain support | Multiple domains can be configured based on the package. |
IV. CDN Acceleration Testing Methods
We adopt curl Test static resource responses from different regional nodes, with metrics including: DNS resolution time, Time to First Byte (TTFB), overall response time, and HTTP status codes.
curl -o /dev/null -s -w \ DNS: %{time_namelookup}s\n Connect: %{time_connect}s\n TTFB: %{time
"DNS: %{time_namelookup}s\nConnect: %{time_connect}s\nTTFB: %{time_starttransfer}s\nTotal: %{time_total}s\nHTTP: %{http_code}\n" \

V. CDN Acceleration Test Results
| Test Area | Time to First Byte (TTFB) | Total(s) | HTTP Response Codes |
|---|---|---|---|
| Vietnam (VN) | 0.036 | 0.114 | 200 |
| Singapore (SG) | 0.050 | 0.142 | 200 |
| Japan (JP) | 0.078 | 0.176 | 200 |
| United States (US) | 0.130 | 0.262 | 200 |
Overall, BizFly Cloud demonstrates exceptional stability across Southeast Asia, with notably low latency for local access in Vietnam. While latency increases significantly at nodes in Japan and the United States, it remains within acceptable limits.
VI. DDoS Attack Stress Testing Solution
Employing a medium-scale HTTP flood attack to simulate real-world business threats, we observe how BizFly CloudCDN edge nodes perform under actual traffic conditions.
| Test Item | Explanation |
|---|---|
| Attack Type | HTTP GET Flood |
| Peak requests | Approximately 35k–50k requests per second |
| Duration | 15 minutes |
| Key Performance Indicators | Normal Access and Origin Server Load |
VII. DDoS Stress Test Results
| stage | HTTP 200 | HTTP 403/429 | Origin server load | Availability |
|---|---|---|---|---|
| Before the attack | 99.91% TP3T | 0% | 11% | 100% |
| Under attack | 92.71 TP3T | 7.11 TP3T | 18% | 99.31 terabytes |
| After the attack | 99.81 TP3T | 0.21 TP3T | 12% | 100% |
During this round of testing, BizFly CloudCDN effectively diverted abnormal requests, maintained stable normal access, and demonstrated excellent control over origin server load.

IX. Frequently Asked Questions (FAQ)
Q1: Does BizFly CloudCDN support custom certificates?
Supports uploading custom SSL certificates; you may also use the system default certificate.
Q2: Is there a trial data allowance?
New users typically receive a small amount of trial traffic, but the specific quota must be confirmed in the console.
Q3: Is it suitable for optimizing domestic access?
Visits to Vietnam and Southeast Asia show significant improvement, but visits to mainland China require link testing.
Q4: Can it withstand a large-scale DDoS attack on its own?
Basic protection is effective. For medium to large-scale attacks, it is recommended to combine with upper-layer security policies or third-party cleaning solutions.
