Maybe IBM's Mainframe? I mean reliable hardware, etc.
Same would have been said of running IBM mainframes in the 1970's no?
IBM does this with their mainframes.
It's not a mainframe unless IBM ships 6 entirely different OSes for it.
This is a good article on the subject: https://arstechnica.com/information-technology/2023/07/the-i...
Surprised they’re still not on IBM Mainframes
Ex-IBMer here. I worked with WebSphere (IBM's Java App Server) on zOS, and am by no means a Z-series expert.My understanding is that these machines are amazing at IO, and handle virtualized environments incredibly well (and have so for decades) (e.g. thousands of Linux machines running).If you need raw CPU performance then a mainframe is not for you. If you need competitive pricing then a mainframe is not for you. If you have a mainframe and need a have an expiring agreement then this mach
I think IBM actually has something like this for their mainframes right?
I am not a mainframe guy, but AFAIK mainframes are very special beasts. Especially they guarentee very high aviability and have special hardware features to support this guarentees. So you do not use them in the first place if you are not more scared of downtime, than of hardware costs. And with this comes a specific very conservative style of software development. If it ain't broken, don't fix it. So a lot of the mainframe code is very old and will only be replaced, if the company is replaced b
IBM has been doing this for decades with mainframes.
