SpeedSize’s infrastructure is built on Amazon Web Services (AWS). SpeedSize solution can’t be deployed on-premise or blackboxed and is only available under the SaaS model. However, single-tenant deployment is available. While other cloud or CDN solutions may be able to proxy SpeedSize responses, they may lose some SpeedSize-specific features, such as adaptive delivery and global data replication, resulting in reduced performance. For the best results, we recommend using SpeedSize CDN natively to fully leverage all available optimization features.
