Wow Impressive! Yes, it's about time I upgraded to one of those Bad Boys

you don't one of those, you want one of these

Netflix? It's Owly remember, I think he's only just switched to VHS

There's a lot of truth in that

Until it goes wrong - Amazon's huge EC2 cloud services crash permanently destroyed some data.

Cue tech heads response...

None of their hardware died (so it doesn't really relate to what I said :P )

This was caused by three things hitting at once

-bad backup procedures
-Engineer incompetence during an upgrade
-a bug in their software

A similar perfect storm of combined errors would wipe out all the data for a non-cloud service.

One of their engineers managed to goof and internally isolate an entire section of nodes from the network. Said nodes couldn't access sufficient backup facilities to store all their information, so a small sliver of data within them was lost. At the same time bugs in Amazons cloud software caused other nodes to start freaking out due to not being able to access the isolated nodes, causing them to bring down other services (without data loss).

No tech is 100% resistant to bad implementation, human stupidity and poor development.

Yeah 'cos data has never been lost on servers hosted inside a companies office.

A web site can also be hosted on the cloud so that (under the surface) it is distributed across multiple nodes around the world as demand dictates. You are highly unlikely not to be near one of the nodes hosting it and a catastrophe of sufficient scale to eliminate the hardware supporting that web site would need to also be big enough to destroy a significant portion of the human race.

I see. What does that mean? Why is it different from being hosted on the public Internet?

The cloud is all about shared dynamic use of distributed resources.

A web site can be hosted on a single machine. All well and good but if you are physically distant from that server, or if the machine the server is sitting on goes down, you will have access problems. If a lot of people try to access the site at the same time, it will chug down to being almost unusable or seize up altogether.

You are highly unlikely not to be near one of the nodes hosting it and a catastrophe of sufficient scale to eliminate the hardware supporting that web site would need to also be big enough to destroy a significant portion of the human race. The number of nodes assigned to it can also dynamically scale as demand dictates, allowing it to run equally well when 1 person or 1 million people are accessing it.

This is very important for high-bandwidth internet based services (a few of which have already been listed in this thread). A lot of services that anyone not approaching retirement age takes for granted, just would not work without the cloud overcoming the technical problems of access, redundancy and scalability on the fly.

You don't use netflix?
Amazon prime?
Channel 4 on demand?
Amazon?
GitHub?
BitBucket?
Evernote?
Spotify?

Personally I'm not interested in 3D printing, but the cloud is very relevant to me - and it also makes me rather a lot of money

The Cloud

3D printing

Can't envisage any conceivable situation where either would be remotely relevant to me (for my own use anyway).

3D printing means I can fabricate parts for my Morris! No hunting around through boxes at swap meets. - well okay its probably a bit of a ways off and my lovely will probably fall to dust by that time. But ya gotta dream sometimes.

The internet of things: more total bollox.

Cars stuffed so full of electronics that they're unrepairable.

The cloud.

Orifice365.

- internet of things..don't tell my brother-in-law, he's making millions off that.

- Now this is why I drive a 25 yearold banger. and guess what? Its the most damn reliable car I have.

- Okay so its my job at present, so Yippeee!. But I do want to retire to teaching! (arthritis kicking in)

- office 365 - the best thing out there.
at least on the cloud I won't (hopefully) have to worry about my data on 3.5" floppy or the data on 1/4" tape that I can no longer access because who would have thought those would become obsolete!

[VectraMan]

All those services are hosted on the public cloud.

The slow cooker.

It's just a small oven that's not quite as good as a big one so it takes longer.

Get over it.
