Cloud DDoS Protection Services: Technical Documentation

This document details the hardware and operational characteristics of our Cloud DDoS Protection Services. This service isn't a single machine, but a globally distributed network of hardware and software designed to mitigate Distributed Denial of Service (DDoS) attacks. This documentation will cover the core building blocks, performance characteristics, recommended use cases, comparisons to other solutions, and maintenance considerations. This configuration utilizes a multi-layered approach, blending hardware acceleration with sophisticated software analysis.

1. Hardware Specifications

The Cloud DDoS Protection Services infrastructure is built upon a distributed network of strategically located Points of Presence (PoPs) around the globe. Each PoP is equipped with redundant hardware to ensure high availability and resilience. The following specifications detail the core components found *within* each PoP. It's important to note that the exact configuration can vary slightly based on geographic location and capacity needs, but the following serves as a representative baseline.

The core of our DDoS mitigation capacity resides in specialized hardware appliances. These appliances are not general-purpose servers; they are designed specifically for high-throughput packet processing and real-time threat analysis.

Component Specification Quantity per PoP (Typical) Notes
**DDoS Mitigation Appliances (Core)** Custom ASICs (Application-Specific Integrated Circuits) for packet processing 20-80 (Scalable) ASICs are optimized for Layer 3/4 and Layer 7 DDoS mitigation techniques. See ASIC Optimization for DDoS for details.
**CPU (Mitigation Appliance)** Intel Xeon Gold 6348 (28 cores, 56 threads) 2 per Appliance Used for complex traffic analysis, signature updates, and control plane functions.
**RAM (Mitigation Appliance)** 512 GB DDR4 ECC Registered RAM 2 per Appliance High memory capacity is critical for maintaining stateful analysis of network flows. Refer to Memory Management in DDoS Mitigation
**Storage (Mitigation Appliance)** 2 x 1 TB NVMe SSD (RAID 1) 2 per Appliance Used for logging, signature databases, and temporary storage. SSDs are chosen for low latency and high IOPS. See Storage Considerations for DDoS Mitigation
**Network Interface Cards (NICs)** 100 GbE QSFP28 Ports (Dual) 2 per Appliance High-bandwidth NICs are essential to handle large attack volumes. Utilizes SRIOV for increased efficiency. See Network Interface Card Selection
**Firewall/Load Balancer Appliances (Edge)** Fortinet FortiGate 600F series or equivalent 4-16 (Scalable) Provides initial filtering and traffic redirection. Can also act as a global server load balancer. See Firewall Integration with DDoS Protection
**Network Switches (PoP Core)** Cisco Nexus 9800-32T or Arista 7508 2-4 (Redundant) High-performance, low-latency switches for internal PoP communication. Supports VXLAN and BGP. See Switching Architecture for DDoS PoPs
**Network Connectivity** Multiple Tier 1 ISPs (Redundant) N/A Ensures high availability and diverse routing paths. Utilizes BGP Anycast for rapid redirection. See BGP Anycast for DDoS Mitigation
**Power Supply** 2000W Redundant Power Supplies (80+ Platinum) 2 per Rack High efficiency and redundancy are critical.
**Cooling** In-Row Cooling Units As Needed Maintains optimal operating temperatures for high-density hardware. See Thermal Management in DDoS PoPs

We also utilize specialized hardware for specific attack vectors:

  • SSL/TLS Decryption Appliances: Dedicated hardware for accelerating SSL/TLS decryption, crucial for mitigating encrypted DDoS attacks. Utilizes Cavium NITROX processors.
  • Network Taps & SPAN Ports: Used for real-time traffic monitoring and analysis.
  • Deep Packet Inspection (DPI) Engines: Hardware-accelerated DPI for identifying and blocking malicious payloads.

2. Performance Characteristics

Our Cloud DDoS Protection Services are designed to handle multi-terabit attacks. Performance is measured using a variety of metrics and benchmark tests.

  • **Maximum Mitigation Capacity:** > 15 Tbps (as of Q4 2023) - This capacity is dynamically scalable. See Scalability of DDoS Mitigation Services
  • **Packet Loss During Mitigation:** < 0.1% (under normal operating conditions). Loss may increase during extremely large volumetric attacks, but is minimized through intelligent traffic shaping.
  • **Latency Added During Mitigation:** < 5ms (typically). Latency is minimized through hardware acceleration and optimized routing. See Latency Impact of DDoS Mitigation
  • **Concurrent SSL Connections:** > 10 million
  • **HTTP Request Rate:** > 500 million requests per second
  • **DNS Query Rate:** > 200 million queries per second
    • Benchmark Results (Example):**

We regularly conduct benchmark tests using industry-standard tools and simulated attack traffic. The following is a representative example:

Attack Type Attack Volume Mitigation Success Rate Latency Impact
Volumetric UDP Flood 10 Tbps 100% < 2ms
SYN Flood 5 Tbps 100% < 3ms
HTTP Flood 200 million RPS 99.9% < 5ms
Slowloris 100,000 concurrent connections 100% < 5ms
DNS Amplification 5 Tbps 100% < 2ms
Application Layer Attacks (OWASP Top 10) Variable > 95% < 10ms
    • Real-World Performance:**

In real-world scenarios, our services have successfully mitigated attacks ranging from small-scale probes to massive volumetric attacks exceeding 10 Tbps. We have a documented track record of protecting against a wide range of DDoS attack vectors, including:

  • Volumetric Attacks (UDP Floods, ICMP Floods, DNS Amplification)
  • Protocol Attacks (SYN Floods, ACK Floods, Ping of Death)
  • Application Layer Attacks (HTTP Floods, Slowloris, RUDY)
  • Encrypted Attacks (HTTPS Floods, TLS Fragmentation Attacks)
  • Multi-Vector Attacks (Combinations of the above)

See Real-World DDoS Attack Examples for case studies.

3. Recommended Use Cases

Our Cloud DDoS Protection Services are ideal for a wide range of applications, including:

  • **E-commerce Websites:** Protecting online stores from revenue-disrupting attacks.
  • **Financial Institutions:** Ensuring the availability of online banking and trading platforms.
  • **Gaming Servers:** Maintaining a stable gaming experience for players.
  • **Content Delivery Networks (CDNs):** Protecting the CDN infrastructure from overload. See CDN Integration with DDoS Protection
  • **DNS Providers:** Ensuring the availability of DNS resolution services.
  • **Cloud Service Providers:** Protecting cloud-based applications and infrastructure.
  • **IoT Platforms:** Securing Internet of Things devices and services.
  • **Any Internet-facing Application:** Any service that relies on internet connectivity and must remain available.

The service is particularly well-suited for organizations that:

  • Lack the internal expertise to build and maintain a dedicated DDoS mitigation infrastructure.
  • Require a highly scalable and resilient solution.
  • Need global protection.
  • Demand low latency and minimal impact on legitimate traffic.

Our service differentiates itself through a combination of hardware acceleration, a strategically distributed network, and granular control over mitigation policies. See Competitive Analysis of DDoS Protection Providers for a more detailed comparison.

5. Maintenance Considerations

While our Cloud DDoS Protection Services are fully managed, understanding the underlying infrastructure is important.

  • **Cooling:** Each PoP utilizes in-row cooling units to maintain optimal operating temperatures for the high-density hardware. Regular monitoring of temperature sensors is performed remotely.
  • **Power Requirements:** Each PoP requires significant power capacity (multiple MW). Redundant power supplies and backup generators are in place to ensure uninterrupted operation.
  • **Network Monitoring:** 24/7 network monitoring is performed to detect and respond to anomalies.
  • **Software Updates:** Firmware and software updates are applied regularly to maintain security and performance. These are typically performed during off-peak hours to minimize impact. See Software Update Procedures for DDoS Appliances
  • **Hardware Redundancy:** Redundancy is built into every aspect of the infrastructure, from power supplies and cooling systems to network connections and mitigation appliances.
  • **Physical Security:** PoPs are located in secure data centers with restricted access.
  • **Capacity Planning:** We continuously monitor traffic patterns and adjust capacity accordingly to ensure we can handle future attacks. See DDoS Capacity Planning and Forecasting
  • **Log Analysis:** Detailed logs are collected and analyzed to identify trends and improve mitigation techniques. Log Management and Analysis for DDoS Mitigation
