Well it does; not every company needs their own data centres

Makes sense to share data centres at a specialised company

someone even punted putting a big data project in AWS. like ... what.. do you even under... no you dont.

Urmm, cloud is just storing your data in another companies physical servers

its the bills

Yea but they pale in comparison

AWS for some use cases isn't cost effective

i couldnt even save money running a goddamn forum server of my own

To long term running costs of data resources, land, maintainable buildings

Cleaning and office staff for the data centres

tech debt

Upgrades

It’s a huge amount of work

if you already have your own datacentres the cost benefit figures are quite a bit different

Having your own enterprise level data centre

a couple of projects ended up staying on premesis because AWS was simply too expensive for them

storage particularly is nasty. i did official AWS training a while back and part of the training is an explanation of where you get charged. and then i realised just how much money amazon must make from this

Yea they make money

They are a business

But cloud does make sense in a lot of cases

You can fire a lot of your staff you don’t need to manage the data

Resource costs are hugeeeeeee

i suspect that quite a few cloud hosted people did not in fact accurately work out how much they could end up paying, it's also designed to vendor lock you

Vendor locking is why I keep shooting down the idea at work

That and I simply don' trust Amazon

i trust them honestly

But they're going ahead and using it anyway because they have no choice, so i'll get overruled on everything, then shit will go wrong and i'll tell them I told them so

Which happens alarmingly regularly

as much as i trust any corp anyway, but theyre not as evil as google at a cursory glance

Well

They’re evil to their staff

Warehouse workers and such

but speaking as someone who used to have specific responsibility for services *definitely working all the time* it would take a hell of a cost saving to not want to look after it personally.

Depends on the size

My company is lloyds

Their data centre in Leeds

Is fucking HUGE

So fucking expensive to maintain

It’s their biggest building

you can get a bit of paper from amazon citing 99.99% uptime (not sure if they do 5 9s?), at 3am in the morning when shit is totally broken that piece of paper is worth absolutely nothing. your customers dont care about the piece of paper either, they hold the business responsible

so im expecting our 'zomg cloud' phase to end the moment someone puts something actually critical there and it breaks
