Azure CDN vs. Imperva CDN

Azure CDN has at hand an infinity of applications and tools to implement in your system and have better control of your data in a clean and secure platform on the web, we recommend this program since the percentage of solutions provided by this program is very high and find a way to make each user's job easier.

Incapsula really exceeds if you have a very large amount of traffic, it is a truly durable and resilient WAF. Global load balancing, increased security, added caching, smaller number of sites (but very important)? Then I would recommend Incapsula. Incapsula is always additive to features your infrastructure has and it does those well, so I would always advise using it if your site has high traffic, is business critical, or accesses sensitive information through a SQL backend.

• New websites can be boosted up quickly
• Easily scalable according to our performance requirements
• Easy integration with other Azure services
• You only pay for what you need

• For the longest time they didn't have a robust SDK. They have one now, but it could be better.
• The different flavors of Azure CDN (Akamai, Verizon, etc) have different costs, but not well differentiated features. Might be confusing to new users.
• I'm not overly familiar with it, but AWS does have a programmability in their CDN offering (Lambda @ Edge) and Azure doesn't seem to have an equivalent (Azure Functions is region-specific).

• CDN functionalities are secondary and cannot be compared to a top-level CDN.
• The WebGUI interface of the dashboard is very improvable. They have been changing the UX for years and it is disjointed and with services that have not yet been migrated.
• The analysis of WAF attack logs is insufficient. It is difficult to analyze attacks of past hours, event filters are missing. It is complicated to analyze the chronology of an attack.
• There are extra modules to improve the attack logs analysis but they are expensive and add little.

I give it 9/10 rating because it solved my problem by Caching my website content on global servers to load faster.

Great support from the team whenever we're stuck. Very proactive in resolving issues and also making changes as per the requirements of the organization.

We did not evaluate any other CDN's before we selected Azure. We heavily use Azure for our development and infrastructure efforts so choosing the Azure CDN was easy. The only thing we compared it to was standing up a Windows Server VM and pointing a CDN URL to it allowing it to serve as a file server, which was much more cumbersome.

• Azure CDN reduced origin instance load by removing the need to constantly serve large numbers of static files, meaning applications can be deployed with smaller/fewer instances.
• Azure CDN reduces apparent load times to customers by serving cached files out of POPs in the local region of those clients, instead of requiring those clients to make multiple, lengthy requests through to the origin servers.

• It's an expensive product if you have a lot of traffic volume, but I feel confident with their WAF.
