Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.
Muhammad ZaheerNazir - PeerSpot reviewer
Helps to handle edge cases and has purge features
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.

Quotes from Members

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

Pros

"Easier http to https redirect using page rules"
"The most valuable features of the solution are performance and security."
"I like Cloudflare's application gateway and DDoS protection."
"The most valuable feature is its usability."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The most valuable feature of Cloudflare DNS is security."
"The solution is very good at mitigating threats."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product helps our organization to access sites located in different regions quickly."
"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."
"Its initial setup process is straightforward."
"Compute@Edge features are valuable to me."
"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."
"I enjoy engaging in discussions with colleagues possessing unique expertise. I leverage the three platforms—Azure, Google, and AWS extensively. This allows me to offer diverse solutions to customers, commonly referred to as a multi-cloud approach."
"I like that CDN offers a routing feature."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"It is a stable solution."
"The UI is very intuitive."
"We use the product for faster content delivery with low latency."
 

Cons

"Integration involving API with other products could be more user-friendly."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"The solution could be more user-friendly."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"Technical support is lacking."
"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."
"Fastly's customer service area needs improvement."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"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."
"The solution's pricing could be better."
"Support is not that great."
"The product should provide improved bot detection and management."
"We have experienced issues with switch connectivity."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"They should include configuration for cache rules."
"Windows Azure CDN should lower its prices."
"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."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The product's pricing is minimal compared to other products."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"A free version of the solution is available."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free version."

"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"The tool's pricing is cheap."
"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."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"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."
