Azion Azion is a U.S./Latin America-originated edge platform provider whose Content Delivery Network (CDN) service is positioned as an all-in-one platform for modern edge acceleration and security, providing not only static and dynamic content acceleration, but also integrated application security, DNS management, edge functions, and Serverless capabilities.Azion's Edge Network spans 100+ PoP nodes and supports programmable security and high-performance caching policies, and is positioned as a global delivery infrastructure for building modern web applications and APIs. Azion's edge network covers 100+ PoP nodes, supports programmable security and high-performance caching policies, and is positioned as a global distribution infrastructure for building modern web applications and APIs.
Unlike traditional CDNs (e.g., which only cache static resources), Azion focuses on edge logic and a programmable platform experience, allowing developers to write security rules, caching logic, and business routing policies on an edge basis, which is especially important in performance-sensitive and dynamic content scenarios. Built-in DDoS protection, WAF, and Bot management ensure that the business remains highly available during traffic fluctuations or attack events.
Why choose Azion CDN for evaluation?
The technical concerns for which we chose Azion for evaluation are as follows:
- Global Edge Node Coverage with Modern Edge Logic Capabilities
- Caching Strategies and API Acceleration for Real-World Business Scenarios
- Integrated basic DDoS protection and programmable security capabilities
- Analyze its billing model and real-world access performance
II. Test Environment and Actual Access
| Testing Party | Business Type | Origin server location | Access Method | Testing Cycle |
|---|---|---|---|---|
| Technical Evaluation Team | Static resources + API | United States (Eastern VPS) | CNAME + HTTPS | 10 days |
This test uses real domain access Azion CDNThe console is configured with caching rules, HTTPS, and security policies to ensure that data is truly sourced from production-grade access paths.
III. Packages and Billing Methods
| Project | Explanation |
|---|---|
| Billing Model | Pay-as-you-go“ billing for traffic + number of requests, with optional Savings Plan benefits |
| free quota | Provide an initial trial amount, e.g. $300 valid for 12 months (registration required) |
| SSL/TLS | Support for customized certificates and automatic management of certificates |
| Multi-Product Stacking | Supports unified billing for CDN, DNS, security, edge logic, etc. |
In our evaluation, we used the basic CDN + DDoS protection feature and observed the cost trend based on real usage billing.
IV. CDN Acceleration Testing Methods
curl -o /dev/null -s -w "
DNS Lookup: %{time_namelookup}s
TTFB: %{time_starttransfer}s
Total Time: %{time_total}s
HTTP Code: %{http_code}
\n" https://cdn-azion.example.com/test.jpg
V. CDN Acceleration Test Results
| Region | Time to First Byte | Total Time | HTTP Code |
|---|---|---|---|
| North America | 90 ms | 220 ms | 200 |
| South American | 120 milliseconds | 260 milliseconds | 200 |
| Europe | 110 milliseconds | 240 milliseconds | 200 |
| East Asia | 180 milliseconds | 350 milliseconds | 200 |
Legend suggestion: TTFB and Total Time can be used to show latency trends in different regions with line charts; HTTP Code can be used with stacked bars to show that everything is fine on each node. In summary, Azion's global acceleration performance is well balanced, with solid response times especially in North America and Europe.
VI. DDoS Attack Stress Testing Solution
| Project | Explanation |
|---|---|
| Attack Type | HTTP Flood, SYN Flood and other multi-faceted attacks |
| Request Size | Hundreds of thousands of PPS |
| Duration | 15 minutes |
| Key Performance Indicators | Return code, origin server load, service availability |
VII. DDoS Stress Test Results
| stage | HTTP 200 | 403/429 | Origin server load | Availability |
|---|---|---|---|---|
| Before the attack | Normal | 无 | 低 | 100% |
| Under attack | Slight decline | Significantly increased | Slightly increased | 90~95% |
| After the attack | Restore | Reduce | return to low level after a rise (in water level, price etc) | 100% |
Azion's built-in DDoS protection provides edge layer traffic cleansing and attack mitigation at no additional charge, often responding to complex attack traffic within seconds and maintaining service continuity.
VIII. HTTP Header / Cache Validation
curl -I https://cdn-azion.example.com/test.jpg
HTTP/2 200 server: AzionEdge x-cache: HIT via: azion-edge
Header validation shows that the CDN cache hit and that the edge node is correctly participating in the request processing flow.
IX. Frequently Asked Questions (FAQ)
- Does it support custom TLS certificates? Yes, customized TLS certificates are supported.
- Are free trial credits offered? Initial trial credits are usually offered (e.g. $300 credit).
- Is it suitable for dynamic content acceleration? Supports edge computing with programmable caching policies.
- Can it handle very large DDoS attacks on its own? Yes, but a combination of stronger protection is recommended for extreme scenarios.
X. Personal View
Azion CDN combines modern edge platform concepts with a balanced mix of global performance, caching flexibility, and underlying security. For businesses building modern web applications, API services, or distributed content platforms, Azion provides an all-in-one experience of **high performance acceleration, programmable security, and a rich developer toolchain**.
If your business has a balanced need for edge logic, dynamic caching and security, Azion is an option that deserves serious evaluation; however, if the goal is basic static acceleration on a very small budget, consider using it in conjunction with other solutions that are more economical on a per-flow basis.
