Overview
CDNSun, founded in 2012, is a content delivery network provider based in Prague, Czech Republic. It offers services like website acceleration, video streaming, and software delivery through a network of over 50 points of presence (PoPs) worldwide. Its customer base includes businesses seeking cost-effective CDN solutions, particularly small to medium-sized enterprises. CDNSun emphasizes affordability with a pay-as-you-go model and a 15-day free trial. The service supports HTTP/2 and provides free shared SSL on its *.r.worldssl.net domain.
Google Cloud CDN is a content delivery network integrated with Google Cloud. It sits behind Google Cloud Load Balancing to cache and serve HTTP(S) content from edge locations. Typical users are teams already running workloads on Google Cloud that want CDN caching, signed URLs, modern TLS, and consistent operations across the platform. The service emphasizes policy-driven caching, fast invalidation, and security integration through Cloud Armor. Pricing follows a pay-as-you-go model that varies by region and usage.
Network & Architecture
CDNSun operates more than 50 PoPs across five continents, including locations in North America (e.g., Atlanta, Chicago, Dallas), Europe (e.g., Amsterdam, Frankfurt, London), Asia (e.g., Hong Kong, Singapore, Tokyo), South America (e.g., Sao Paulo), and Australia (e.g., Sydney). All edge servers use SSD drives for faster data access and have redundant connectivity to robust internet networks. The network supports global content delivery with a focus on reducing latency for websites and streaming services. Specific routing or peering details are not publicly disclosed, but the provider claims strong performance for global audiences.
Google Cloud CDN uses Google’s global edge and backbone to terminate HTTP(S) traffic close to end users and fetch from origins over Google’s private network. Coverage spans major regions in North America, Europe, and Asia-Pacific, with additional presence in other geographies. Strengths include integration with Google Cloud Load Balancing, Anycast routing, and private backbone connectivity from edge to origin. Limitations can include fewer CDN-specific knobs than specialist CDNs and feature gaps for advanced video packaging.

Pricing
CDNSun uses a pay-as-you-go (payg) model with no monthly or setup fees. A 15-day free trial (free-tier) is available for all services. Pricing is transparent, with custom options for high-volume users, but specific per-GB rates are not publicly listed. SMB-friendly pricing targets smaller businesses. The official pricing page is https://cdnsun.com/pricing/.
Pay-as-you-go pricing with regional rates for cache egress and request charges. Total cost depends on geography, volume, and cache behavior. See cloud.google.com/cdn/pricing for current details.
Integrations & DevEx
CDNSun offers an API-first approach for managing CDN services, including access to real-time logs. It provides integration support via a dashboard and API, with 24/7 technical support through email, phone, and live chat. No specific Terraform or CI/CD integrations are documented. The service includes tools for testing performance gains, such as ping tests and downloadable test files (1 MB and 20 MB).
Deep integrations include Google Cloud Load Balancing for traffic ingress, Cloud Armor for WAF and DDoS protections, Cloud Storage and Compute Engine for origins, and Cloud Logging and Monitoring for observability. Infrastructure as code is supported via Terraform, and a REST API enables CI/CD automation.
When it fits
- Small to medium-sized businesses needing affordable, pay-as-you-go CDN services with a free trial.
- Companies targeting global audiences with video streaming or software delivery needs.
- Developers seeking an API-driven CDN with real-time logs for monitoring.
- Workloads already hosted on Google Cloud that need an integrated CDN layer.
- Teams standardizing on Cloud Load Balancing, Cloud Armor, and Cloud Logging.
- Organizations that want signed URLs, HTTP/3, fast purge, and policy-driven caching.
- Buyers who prefer Terraform and API-first management across cloud services.
When it doesn’t
- Enterprises requiring advanced security features like WAF, DDoS protection, or bot mitigation.
- Businesses needing specialized edge compute, key-value storage, or advanced video features like DRM.
- Users prioritizing extensive integrations with Terraform, CI/CD pipelines, or specific cloud platforms.
- Multi-cloud environments seeking provider-neutral or MultiCDN routing.
- Advanced video workflows needing packaging, DRM, or low-lency live features.
- Use cases requiring built-in image optimization pipelines.
- Projects that rely on WebSocket-heavy bidirectional traffic at the edge.
