Edge caching has transformed response times and delivers faster candidate data globally

Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Our data is cached faster and sites load faster

We use the solution for hosting static web applications. We use it to cache images or files We mostly distribute images through the CDN. Earlier, we were directly caching from the server to CDN. Since we started using the solution, there has been a significant improvement in the response time.…

Quotes from Members

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

Pros

"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."

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

"Fastly has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."

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

More Fastly pros

"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."

"I like that CDN offers a routing feature."

"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."

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

"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 fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."

"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

"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."

"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."

"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."

"The solution's pricing could be better."

"Support is not that great."

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

"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."

More Fastly cons

"The solution’s pricing could be improved."

"I aim to enhance the reporting."

"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."

"The high price of Windows Azure CDN is an area of concern where improvements can be made."

"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."

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

"We have experienced issues with switch connectivity."

"Windows Azure CDN should lower its prices."
