they don't build it this way because cloud is cheap and slow. I have a UCS farm with 2000VMs, connected to 3PB of usable all-flash across 2 arrays, replicated active/active to another array, second-hopped to cloud. That's one site. About 100k users across 2 domains - 1k? I said enterprise. A SAN is not scalable but internal disk is? You need to look up what a SAN is. The reason there is a standing joke with your coworkers is because you don't work on important things that run the world. When 1 minute of downtime costs you over $1mil, your "ripped off" Oracle costs, your SAN costs, etc, are lost in the rounding errors. I can have a SAN have hundreds of arrays, across multiple datacenters, and dynamically grow and shrink my storage needs. It is the definition of scalable. I can have one VM farm vmotion to another VM farm 30 miles away transparently, which will sit on a different array attached to the SAN. What happens when the storage needs of your server outgrow the drives you can shove in there? There are servers and databases a petabyte in size, pushing a million IOPS. They're in charge of money. If there is corruption on the SAN, well it infrequently happens, just like with servers and memory. Twice in my vast experience. You can roll back all writes on the replication software, and usually keep an undo journal a few days long, and something like hourly snapshots. This also protects against cryptoviruses and other types of corruption. This is why people like you work at small companies, fiddling with your cute little projects, while the world moves forward with you on the sidelines. I've been doing this for 20+ years, and have been at most fortune100 companies, in 80 countries. But yeah, your opinion, while being dismissive, is cute. The CIO is the guy in charge of getting this stuff at enterprises. It's clear you don't understand the impact of design. I am guessing you are not at an architect level. There's a reason for that, and a reason other people - the ones you put down in your post, are making the big decisions. People like you would cost the company millions of dollars in loss per year. |
Again, if you read what I said you'll notice that I pointed out that you actually can build decent architectures using enterprisey stuff, it will however never scale horizontally in a resonable way. What happens when you have filled all your shelves in the array box? Ah, you'll need a new $250K box...
Mentioning vmotion and all... yeah so... VSAN et al... brrr... I'll put my trust in the open source world rather than shoddy software from 3rd party vendors trying to appease to the latest fad. Hyperconverge my *ss! =)
KISS is what rules but vendors are busy feeding channels and partners with impossible to penetrate acronyms leaving you in a mess sooner or later.
Focus from these vendors is to keep integration at a minimum, which means API's are usually crappy and achieving a reasonable level of automation is often a chore.
Now there is probably a little percentage of "enterprises" that uses tech in a sane way, but my bet is that the CIO you mention is a blockchain expert, as well as putting AI at the top of strategic actions to "implement" this year.
He probably have commissioned a pre-study from Accenture that outlines these strategic imperatives.
This is of course a little rant, but also true for the 90% of the 90% mentioned.
Don't be defensive and close minded. That's what's leaving most enterprises in the dust. There's just a lot of inertia inherent within certain businesses that will let them continue to burn through cash on pointless tech for yet a while.
