The Case for CloudFlare

Several of the Layer 3 and 4 features are built in. However, services such as CloudFlare also offer additional, commonly needed services around globally delivered content. This includes:

Breach protection : CloudFlare to protect our network from breaches as well as to reduce bandwidth on the servers themselves and therefore freeing up the bandwidth for our other projects.

Instant DNS Propagation:   Instant DNS propagation across the internet is rare. CloudFront can offer such propagation and can also be used for DNS hosting  (AnyCast DNS – which also supports DNSSEC + IPv6).

Free Included SSL:  This is a built-in feature with CloudFlare and you can eliminate internal encryption tools for images and static content such as email obfuscation.

Summary

When picking between a cloud native CDN offering, it is important to ask the question ‘What else can it offer besides Content Delivery?’  Does it offer breach protection? How about SSL Termination or Free SSL? Can I host DNS on the same service? These answers may help you decide between offerings such as CloudFront (AWS)  or Azure Front Door (Azure) and  CloudFlare’s CDN service.
