Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Has provided exceptional performance for handling high web traffic
In my opinion, Windows Azure CDN is one of the best CDNs. We tried to replace it and made a business case to check other options such as Cloudflare, and we are using Cloudflare and tried Akamai, wanting to explore alternatives from OCI. One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF. Windows Azure CDN is easily integrated with Azure services such as Azure Storage and Azure Web Apps, and sometimes we are using just Azure Front Door while the back end and database will be on OCI. The impact of Windows Azure CDN's dynamic content acceleration on our application performance is very significant. For one of our clients, we could not use anything other than Azure Front Door.

Quotes from Members

"The UI is very intuitive."
"We use the product for faster content delivery with low latency."

Cons

"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
