CloudFlare vs Limelight CDN: What are the differences?

Introduction

Content Delivery Networks (CDNs) are an essential part of modern website infrastructure, serving to distribute content efficiently to users around the world. Two popular CDNs, CloudFlare and Limelight, offer similar services but also have distinct differences. In this article, we will explore the key differences between CloudFlare and Limelight CDN.

1. Network Size and Reach: CloudFlare operates one of the largest CDN networks globally, with over 200 data centers spread across more than 100 countries. This extensive network allows CloudFlare to deliver content closer to end-users, reducing latency and improving website performance. On the other hand, Limelight CDN has a smaller network, with around 80 data centers located in strategic locations worldwide.

2. Web Application Firewall (WAF): CloudFlare has an integrated Web Application Firewall (WAF) that provides advanced security features such as DDoS protection and protection against common web vulnerabilities. This built-in security layer helps protect websites and applications from various cyber threats. Limelight CDN, however, does not offer a WAF as a part of its CDN service, and users may have to integrate third-party security solutions separately.

3. DNS Infrastructure: CloudFlare is known for its robust DNS infrastructure, providing fast and reliable DNS resolution for websites. Additionally, CloudFlare offers free DNS services with advanced features like DNSSEC and DDoS protection. Limelight CDN also offers DNS services, but its emphasis is more on content delivery rather than DNS management.

4. Edge Computing Capabilities: CloudFlare provides Cloudflare Workers, a serverless computing platform that enables developers to run their code at the edge of CloudFlare's network. This allows for the execution of complex logic and real-time customization directly within the CDN network. Limelight CDN, on the other hand, does not offer a comparable serverless computing platform integrated with its CDN service.

5. Analytics and Reporting: CloudFlare offers detailed analytics and reporting tools that provide insights into website performance, traffic patterns, and security events. These reports help website owners make informed decisions and optimize their online presence. Limelight CDN also provides basic analytics but may not offer the same level of detailed reporting and granular insights as CloudFlare.

6. Pricing Structure: CloudFlare offers a range of pricing options, including a free plan for basic CDN services. They also have different subscription tiers based on the level of features and support required. In contrast, Limelight CDN follows a more traditional pricing model, with pricing based on usage and additional charges for add-ons and premium services.

In Summary, CloudFlare has a larger network size and reach, integrated Web Application Firewall, robust DNS infrastructure, edge computing capabilities, advanced analytics and reporting, and flexible pricing options. On the other hand, Limelight CDN may have a more streamlined and focused approach to content delivery but lacks some of the additional features and extensive network coverage offered by CloudFlare.
