Layer 3 or 4 DDoS are absorbed by the CDN as design (IP, TCP ,UDP), the high volume doesn't reach your origin server so you are automatically protected.
But in case of layer 7 DDoS, all application attacks (SQL injections, XSS, Remote file inclusion), you need a Web Application Firewall (WAF) to protect against this kind of threat, the CDN will not "see" and of course not block these attacks (and it's not his role)

Because the CDN have normally a WAF, a reverse proxy and a lot of locations to replicate in miliseconds your site. I know Cloudflare better and this is the response can I answer you.
If you have a CDN, does it mean you don't have to worry about DDoS attacks or will hackers still succeed in carrying out DDoS attacks?
I'm a VAR/System Integrator and I don't see any problem once you have Cloudflare.

CDN is not going to help you to avoid DDoS. The main function of a CDN is to deliver content faster. To mitigate the risk of a DDoS you need a Web Application Firewall (WAF). Todays WAF come with CDN capabilities.

Of course with CDNs people always think about speed.
I see CDNs in a differently. A CDN provides users, and vendors a unique deployment spot based on its location within a network diagram, between the user and the origin web server. Due to this unique location you SHOULD expect more from a CDN than just performance. Why? Because this is the perfect place to layer on ancillary services.
Find a CDN vendor who has service you need, in addition to just plain old performance enhancement. CDN vendors offer all sorts of add on services including:
DNS Management
Malware Detection
Bot Detection
API Security
Web Application Firewalls
2 Factor Authentication
Load Balancing
Threat Intelligence and Fraud Detection
DDoS Protection
Etc.
If you're implementing a CDN as a net new project, stop and ask yourself "Do I have other projects that I can knock out at the same time?"

Downtime overall, ease of deployment, least resistance for buy-in. Is it forward looking and encompassing for future upgrades or requirements with little or no disruption?

"Imperva Incapsula’s stability is what stood out for a vice president of global IT security at an insurance company. He noted, “The stability of the solution is very good. I've never heard of any outages that I'm aware of. It doesn't crash or freeze. There aren't bugs or glitches. It's reliable.”"

It's almost right, but even that don't happen often, it happens (and both outage had a huge impact)
