Before we talk about a content delivery network (CDN), let's talk about your company's website. Maybe it’s for marketing, maybe it’s for ecommerce, maybe it's for sharing cat GIFs. But in 2016, no matter what your company does, it definitely involves a website in some way, shape or form. In fact, visiting your company website is almost certainly one of the first interactions that new customers will have with you. If they find you through an ad, that ad will direct them to your website. If they are responding to an email, they will be clicking on a link to your website. If they speak to one of your salespeople on the phone, they will probably visit your website right after - or even during - the call. If they find you via Google, the link they find will be to your website. Etc., etc., etc.
Acronyms were so much easier in the late 20th century. When it came to “cloud stuff,” all anyone talked about were ASPs, or Application Service Providers. This caused some confusion because asp was also the extension that web sites running on the Microsoft stack used. Asp was (and is) the name used to refer to several species of venomous snakes, which while cool, probably didn’t add to any confusion. Then, as if bitten by an asp, the ASP acronym began to die. It was ultimately replaced by the term SaaS, or Software as a Service. It’s unclear whether the mixed case approach to the acronym that was the draw or if it was just plain convenient to have “as a Service” on the tail end of the expression, but SaaS took off and was ultimately responsible for the creation of a variety of derivative acronyms.
