It's good to receive feedback that helps people determine information that has value to others. It helps us focus on topics with merit.
There are a couple of additional things I'd like to address though, as briefly I can, considering I'm a rather loquacious sort ;)
I think it was @frogzone that brought up the general controversies that typically do follow #Cloudflare around. I have privacy conscious friends on both sides of that widening chasm...
In general it tends to be the developer sorts that although are cautious, reserved usually, when passing around compliments where Cloudflare is concerned, they're also the pragmatists where performance and dare I say security is concerned, and are often quite willing to turn to Cloudflare (specifically, as a #CDN).
With respect to security concerns, it is true that incorporating a CDN does provide a level of obfuscation of the IP spectrum, that is often cited as a major reason by hosting providers for the customer to incorporate/subscribe to CDN services (more often than not, Cloudflare - because they offer better kickbacks (er.... incentives) to hosting providers.
Then there's the hard core privacy concerned folks. #Last_Mile delivery performance considerations typically being much less of a compelling reason to use, let alone pay, for a CDN like Cloudflare to be injected into the website admin's #DNS. This is because, and let's be real here folks, most websites don't generate anywhere near the levels of traffic that their Nginx or Apache Servers can easily serve up, and for folks on the other side of the world from the particular website, a few milliseconds on a clear day is negligible.
Now, if you're running a very busy site, like... Etsy, or even really popular sites with thousands of requests per minute then you can really benefit by spreading your cache around the globe on super fast CDN services. Even a site that receives on average 1 request per second (60 per minute - and that's pretty respectable traffic) doesn't really benefit enough from the #caching related benefits of a CDN to mark a compelling case - the Last Mile Delivery, however, to Oslo, Norway, from a website in Melbourne, Australia... that can indeed improve perceived response by 250ms (2.5 seconds) or so.
So, just like these so-called VPN services, like NordVPN, etc., there needs to be an effort to educate the consumer as to the actual benefits expected for specific matters - some may be important considerations for the consumer, while others may just be a tech support person in a boiler room trying to reach that bonus number for the month... I've seen waaaay too many people purchase services they really didn't need or would receive much benefit from, and many support desk personnel upselling customers with things they probably shouldn't have.
Now, there's another thing I didn't mention - #Denial_of_Service attacks... Good ole #DDoS campaigns. Well, first of all, one should check with their hosting provider - whether they have the benefit of protections against such attacks, and then, weigh the added benefit of using something like Cloudflare to do the same job (are you paying for protection that you might need twice?).
I personally would probably not have included Cloudflare as part of the #HowTo. It can be added at anytime, but some folks swear by it, so it's not that I'm on the fence about Cloudflare, it's just that I look at it more from the engineering and security perspective, with an eye specifically focused on the veracity of any perceived needs by the customer. And I'm not super fond of turning all of that DNS control (and valuable #metadata) to some third party.
I realize that may have only served to raise more questions, so I'll just say that this is why you pay your trusted IT support professionals who make all of their money on labor they've billed you for, to sit down and discuss what you may or may not need, and especially, why 👍
Brenden Eich was invoked by @marathon - and I too, concur that It is only right to measure technology based on it's own merit and capability - without regard to superfluous and unrelated matters of personal politics.
When haters start fomenting hatred, disparaging everyday, average people for their informed choice of technologically capable software relevant to the task at hand, I like to remind those vile, adolescent, sniveling children that they're literally denigrating things like Brave Browser and Soapbox (the platform I'm authoring this post on), while at the same time availing themselves of the full compliment of features that #JavaScript's technology affords them - JavaScript, invented by#Brenden_Eich...
And they have my blessings to completely swear off and forgo ever using JavaScript again - but they won't, will they? Why? Because they're filthy, hateful, hypocrites consumed by their own criminal commiserations.
