About Fastly's Cloud Accelerator
Last updated February 12, 2017
Fastly's Cloud Accelerator provides an integration between Fastly and Google services. Specifically, the integration enables you to connect to Google's Cloud Platform service via peered network interconnections (direct PNIs) directly to Fastly's content delivery network services, thus speeding up your content delivery and optimizing backend workload.
When you sign up for Fastly services and configure a Google Cloud Platform service as your origin server, you designate a specific point of presence (POP) to serve as an Origin Shield that handles cached content from their servers.
Requests from Fastly POPs to the Cloud Accelerator Origin Shields are routed over Fastly's network, which leverages optimized TCP connection handling, quick-start and opened connections to ensure fast response times between POPs and through to the end-user. Fastly ensures that requests go directly to the Origin Shield instead of the origin servers. Only requests that the entire network has never handled will go back to the Google Cloud Platform service.
