Features: Windows Azure CDN's valuable features include scalability, global reach, and integration with Microsoft services. Fastly offers real-time analytics, instant configuration updates, and edge computing capabilities, appealing to tech buyers seeking high performance and dynamic capabilities.

Room for Improvement: Windows Azure CDN could improve its flexibility for users needing more tailored options, enhance its real-time analytics capabilities, and refine its interaction features to compete with advanced competitors.

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

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."

"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."

"Fastly provides CDN, WAF, image optimization, and IP restriction."

"Rate limiting is a good feature that protects from volumetric attacks."

"The product's initial setup phase is straightforward."

"Compute@Edge features are valuable to me."

"The product helps our organization to access sites located in different regions quickly."

"Its initial setup process is straightforward."

More Fastly pros

"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."

"The most valuable feature of Windows Azure CDN is its effectiveness."

"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."

"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."

"I like that CDN offers a routing feature."

"It is a stable solution."

"The UI is very intuitive."

"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."

Cons

"The solution's pricing could be better."

"The product should provide improved bot detection and management."

"What I don't like about Fastly is that they charge a heavy price."

"Support is not that great."

"Fastly's customer service area needs improvement."

"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"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."

"Exploring shared access solutions with cloud accounts would be a beneficial choice."

"It is not a weakness of Windows Azure CDN; rather, it is the fact that it is outside Saudi Arabia, leading to some regulation issues."

"We have experienced issues with switch connectivity."

"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."

"I aim to enhance the reporting."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
