How cool are those half racks!!!

Man. A small stack of C-Series, a VNX 3300 and some management/support magic sauce and that could be a little Vblock! Hmmmm....

OMG... Whilst I appreciate that "md76040303317" is trying to make a point (albeit in *very* poor taste), thankfully the post is in part a hoax (see section of post thread below).

I have managed complex life critical/mission critical systems for a large Medical Research organisation in the UK; whilst I did everything practicable to prevent unforeseen IT disruption/outages (off-site DR facility, fail-over circuits/servers; etc.), when I worked on implementing a BCM/DR plan, we also had appropriate manual 'last resort' protocols in place for absolutely critical systems; so that in the event primary and secondary IT services let-us down, we could work-around these.

This is a home based system, not an intra-hospital system. So the promised 99.95% uptime is fine. But this situation showed that the promised 99.95% = fiction...
BTW. All three servers are working - hopefully the situation will remain stable."

HA HA HA - You crashed Joe's office...good call. Whose MB Air is that on his desk? Let's hope Wade "liberated" it on the way out.

BTW - spot on with your AWS stuff. As our world becomes more simplified and commoditized, one phrase will begin to resonate MUCH louder:

Caveat Emptor.

AWS's SLAs (which have not changed since 2008), says EC2's "Service Commitment" is 99.95%; S3's is 99.9%...if you go premium. These are AWESOME SLAs for stretching into temporary hybrid cloud space when needed, but should NEVER EVER EVER EVER be considered for the sole location of "life critical" (to borrow from your link) applications.

And THAT is the second challenge of a commoditized Public Cloud - it gives more people the ability to simply bypass a seasoned and cynical IT pro who ALWAYS thinks in pairs - "If this function is so critical, what happens when it goes down?". You don't need to think about that if you have a dream, a credit card, and access to AWS.

May we live in interesting times.

> If apps were written to have app-level resiliency and leverage multiple AWS availability zones, they would have been OK.

I think that was the problem here -- all of the availability zones in US-EAST had the problem. People who were following Amazon's guidelines were still hooped.

The way that Amazon bills for traffic between regions makes it expensive to replicate data between regions, and they don't offer a solid way to use both data centres at the same time if you do so.

I forsee some new product offerings along those lines though ;)

But I agree -- not a reason to dismiss *wavy hands* the cloud

Mike @NetApp - Great comments on AWS.

It is a scary proposition when speaking with customers and it becomes obvious 'The Cloud' does not always go hand in hand in their minds with a conversation about doing it right - things to keep applications and data properly protected and available.

"Cloud" does not equal 'Safe" in all cases, and it never absolves the IT buyer from building and buying the solution that meets the required SLA's. There has always been a basic set of business requirements in every shop, and the big question is this: Will The New Architecture Meet My Requirements. The answer is a solid YES, but only if we ignore the glitter and keep our core requirements close at hand. Else, nasty surprises lurk.

It brings me to an adjacent point, one that I've experienced as a vendor(mostly) and a customer (a little).

Who is at fault when a failure like this occurs? In my experience, everyone owns a piece of the blame - vendor, customer, consultant - all of them. I've never seen a disaster occur that has brought a business to it's knees where it was not a perfect storm of circumstances owned by all the participants. Ever.

It does happen occasionally that the full set of the accused stand up together and take ownership, make speedy repairs and then strengthen not only their infrastructure, but the business and personal bonds between them. That is a real big win in the face of failure. People doing good by one another.

Just curious -- what do you use for the half-height racks? I'm considering one for my home server setup, and those look pretty good :)

Love the way that Plan B is the half racks whereas everyone else has that as plan A and Cloud Plan B.
Outages happen always will I'd much rather Amazon is managing my outages not some snotty 20 yearold who is more concerned with getting back to gears of war.
