CloudTech<\/em>. “He said why, and I said because anything can go over IP, so why are you stating the bleeding obvious?<\/p>\n“He was coming from a traditional voice and telecoms background,” Finnie adds. “He said you can speak over IP…well of course you can, it’s a packet.<\/p>\n
“Anything you can shove into a packet you can put over an IP network. Doesn’t mean it’s going to work, but it means you can put anything over it.”<\/p>\n
Ivan Harris, cloud services manager at Eduserv, argues the ‘as a service’ model is useful for customers.<\/p>\n
“I think people like nice pigeonholes to put things in, so you can find stuff easily,” Harris says. “I think that’s the way Gartner makes its money in defining what those pigeonholes are.<\/p>\n
“There’s loads of –aaS, and I think the –aaS badge is useful to help you find things,” he adds. “I think it’s going to stick for some time, and it’s going to proliferate as well.”<\/p>\n
The overall effect of XaaS would be fewer data centres, with more IT resource and power located off-premise. This will come about as the public cloud continues to grow in stature.<\/p>\n
A recent David Linthicum thought piece, published on CloudTech<\/em>, argues the private cloud’s new role as an entry point for organisations to public cloud. Finnie argues there’s similar confusion over the definition of public and private, admitting he’s “always hated” the definition of both.<\/p>\n“The trouble is people assume with public cloud you get that elasticity, you get that flexibility, but you don’t get security. That’s not true,” he says. “That’s you making an assumption of what public cloud is.<\/p>\n
“Not all cloud computing platforms are purely internet-facing. The version 2 ones which are network integrated give you the option to have that public cloud interface, and experience, and elasticity, but in an entirely private domain,” he adds.<\/p>\n
One of Dixon’s tenets for XaaS was analogising clouds with cars. When you buy a car you pay for one service, but different parts are manufactured in different places, and components can be customised to suit the buyer’s needs.<\/p>\n
Interoute also uses the car analogy to describe its offerings, yet Finnie adds a caveat.<\/p>\n
“When I was a kid there were loads of brands of cars,” he explains. “Now, you’ve probably got eight manufacturers worldwide.<\/p>\n
“As an analogy it’s a useful way of thinking about it, because it says at some level…if what you’re buying is a car, which is infrastructure in the analogy, then it is so much about scale, and size, and R&D, and how sophisticated that car’s going to be,” he adds.<\/p>\n
“If you’re going to use a cloud service provider and you’re going to buy from someone who’s a good old boy who’s bought a couple of racks and spun up a bunch of servers, it’s possibly not the smartest thing to do. You might want to use his advice, but you might want to use his advice on something else.”<\/p>\n
So what to conclude? The concept of XaaS has been around for a long time – but then again, so has the concept of cloud. Now, the technology and business needs may be catching up with the aspirations.<\/p>\n","protected":false},"excerpt":{"rendered":"
As cloud computing becomes ever more pervasive, future models will begin to revolve around XaaS. Anything as a service, everything as a service, more as a service, call it what you will. The overall effect is that a new type of service will deliver Iaa…<\/p>\n","protected":false},"author":50,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[],"tags":[],"class_list":["post-11431","post","type-post","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/posts\/11431","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/users\/50"}],"replies":[{"embeddable":true,"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/comments?post=11431"}],"version-history":[{"count":0,"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/posts\/11431\/revisions"}],"wp:attachment":[{"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/media?parent=11431"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/categories?post=11431"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/icloud.pe\/blog\/wp-json\/wp\/v2\/tags?post=11431"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
