What’s the difference between cloud computing and web computing?

Question

What is the difference of cloud computing and web computing?

Both are not local and are mostly accessible via browser then one gets the impression that they are similar concepts.

Answer 1

I’m not going into it, not least because the terms are used very, I would say, randomly.

Has a question here explaining what cloud computing is and brush on the web.

Web

Web computing is one that works on top of the HTTP protocol. This can happen in many ways. The server may be cloud-based or not. Eventually even the customer may be in the cloud, although highly unusual and I don’t know if it makes sense to do this.

Cloud

Cloud computing does not require specific protocols, it only needs to meet some criteria set out in the question linked. The fact of being accessible by the web is a chance, it is something possible, eventual. For the cloud does not matter.

Local

It is necessary to define better what "local" means, but it is a mistake to say that both are not local. In general people use remotely (another physical location), but they can be local yes, and it is more common than it seems. Even if location means running on the same computer, it can still be said that being local is a possibility.

Term

The term cloud today is used as a marketing tool more than an engineering tool. People talk about cloud when it doesn’t go anywhere near that. Some people consider if it’s web, it’s cloud. Some consider even the billing model as a definator if it is cloud, that is, if you charge for the use and not a fixed value, it is cloud.

Usefulness

In fact few organizations need real cloud.

• They need a web.
• They need to have a centralization.
• Remote.
• They need virtualization, even locally.
• Need good organization of resources and deployment and maintenance facilities.

In some cases they may even use cloud technologies, but without the typical cloud scaling feature.

Cost X benefit

Real cloud is usually very expensive (but they sell as if it were cheaper) and it takes away a little of the flexibility of what you can do. It has advantages, but can come cheaper in niches or when compared to something poorly done.

Even the rental of a virtualization is usually more expensive, but there are cases that are more interesting, as well as the cloud by the type of use it will have.

Only take the structure from within the company and pass to third parties without adding any real value is only mismanagement of resources made because someone who goes in fashion for lack of knowledge of what they are doing.

Example

So this site here doesn’t use cloud. When there are real engineers working they don’t fall into market traps.

For example, I have a server that’s essentially used to serve the web. Officially it’s in the cloud, but my hiring isn’t like cloud actually. It’s a virtual instance, it comes out relatively cheap. As the use is very low and in Brazil the costs of data communication are absurd, it ends up compensating. If those specific costs were lower I would have, even something small, here with me.
