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

"Compute@Edge features are valuable to me."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"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."
"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."
"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."
"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."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"It is a stable solution."
"The UI is very intuitive."
"We use the product for faster content delivery with low latency."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"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."
 

Cons

"The solution's pricing could be better."
"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."
"What I don't like about Fastly is that they charge a heavy price."
"Support is not that great."
"I think Fastly could improve by improving the documentation and having some code examples so that it is easier for developers, since at the beginning it becomes a bit complicated."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"Fastly's customer service area needs improvement."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"Windows Azure CDN should lower its prices."
"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."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"The solution’s pricing could be improved."
"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."
"They should include configuration for cache rules."

"You need to pay a premium price for the tool."

"In my opinion, Fastly is priced competitively."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"The pricing has been very competitive."

"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
"The tool's pricing is cheap."
"The solution's price is above the medium range."
"The pricing is extremely high, almost 9 out of 10."
"It comes at a relatively affordable cost."
"The tool's pricing is cheap."
"The pricing of the solution depends on usage and varies based on the company's needs. If you want additional features like advanced logging, it will be pricier. However, it could be cheaper if you don't need those features. It all depends on the resources and requirements."
