GCP Cloud CDN is a content delivery network service by Google Cloud Platform, designed to deliver content with low latency and high performance to users worldwide.
When a user requests content from a website or application, the request is directed to the nearest edge server in the Cloud CDN. The edge server checks if it has a cached copy of the requested content. If the content is cached, it is delivered directly to the user with reduced latency. In cases where the content is not cached, the edge server fetches it from the origin server, caches it locally, and then serves it to the user. Subsequent requests for the same content are then served from the edge server, further reducing response times.
GCP Cloud CDN automatically optimizes the delivery of both static and dynamic content, making it ideal for a wide range of applications, from websites to APIs and streaming content.
GCP Cloud CDN is a valuable addition to various scenarios, especially for businesses with a global audience. Some common use cases for GCP Cloud CDN include:
GCP Cloud CDN, part of Google Cloud Platform's suite of services, is a global content delivery network that accelerates the delivery of websites, applications, and other content to end-users. It leverages Google's extensive network infrastructure, consisting of edge locations strategically distributed worldwide, to cache and serve content from the closest edge server to the user's location. This approach reduces latency and improves the overall performance of web applications, resulting in an exceptional user experience.
GCP Cloud CDN is a paid service, and the pricing structure depends on usage and other factors.
GCP may offer multiple pricing tiers, allowing users to select the one that aligns with their specific needs and budget. Cloud CDN offers a transparent and flexible pricing structure that takes into account various factors, including cacheable content, cache hit/miss, cache egress, cache fill, and HTTP/HTTPS cache lookup requests. The pricing is designed to provide cost-effective content delivery solutions for a wide range of use cases.
Cache Egress: Cache egress charges are applicable when Cloud CDN serves cached content to users. The charges vary based on the destination and your monthly usage. The monthly usage is calculated per project per destination, where the destination is determined by the client's IP address. The cache egress prices are as follows:
Cache Fill: Cache fill charges represent the data required to populate Cloud CDN's caches. Charges vary based on the source and destination of the content. The cache fill prices are as follows:
HTTP/HTTPS Cache Lookup Requests: Cache lookup requests occur when Cloud CDN serves cached content. The GET and HEAD HTTP methods cause cache lookups, while other methods like POST and PUT do not. The price for cache lookup requests is $0.0075 per 10,000 requests.
Requests Sent from Cloud CDN to External Backends: For requests sent from Cloud CDN to external backends, standard Compute Engine internet egress rates apply.
A simple usage scenario for Cloud CDN is shown below:
Pricing category Type of usage Amount Cache egress in North America 500 GiB Cache fill Data transfer to Cloud CDN caches 25 GiB Cache lookup requests GET and HEAD HTTP methods 5,000,000 operations
Total Cost: ~$44.00
