Then again, I've often noticed that being in or out of the MS stack is a bubble, and the other side sees things very differently, so I could definitely be wrong here.
The only reason Amazon vanishing would be significant is because there's not really a competitor in the whole of their space. online booksellers aren't doing online non-book goods delivery aren't doing cloud services aren't doing grocery delivery, etc. Each of those services would be easily replaced, but not by a single company.
Government! Government and enterprise! Neither would function without MS!!
Windows/Active Directory, Windows Server, MS SQL server, SharePoint, and Office all make the world go round in the public and private sectors. You'd have to entirely replace pretty much all corporate infrastructure.
Coke and Pepsi together represent a huge share of the soft drinks people drink. If those two flavors, or even the two companies, disappeared, it would have a notable impact in that a lot of people would find new drinks (plus the significant impact to the supply chains, distributors, etc).
But there are absolutely competitors to fill in the gaps. There ARE other soft drinks. And if none of the existing brands are up to the challenge, in the absence of a huge established market presence, we can easily imagine new companies stepping up.
Just because MS products have a huge presence in the market doesn't mean MS products are irreplaceable.
I would dispute that active directory is irreplaceable. There is literally nothing on the market today that has the functionality and ease of use, and getting anything on the market today to that point would be about as easy as re-writing AD from scratch.
My experiences with AD are anything other than "ease of use", but again, I tend to live outside the MS stack, and it's been 15 or so years since I did anything remotely related (I did a lot of interaction with some LDAP servers, but only interact with AD as an end-user...where I have weird issues like "must authenticate with a userId@domain that is not my actual email address at that domain" or "Have to look up everyone by last name, even though we have 50 Agrawals but only one Preetha" or "can't get a frigging email address without navigating into contact details, and that won't even work if it's a forward email from someone outside" (though that might be Outlook). Voicing these complaints gets me "oh, you just don't have a good administrator", but...just about every place I've been has had these issues, so either AD isn't that easy to use or everything else is REALLY bad.
I'm also uncertain what functionality AD has that isn't specific to integrating with the MS Stack, but that's a literal lack of knowledge, not a criticism.
As for AD: An email address isn't an identity. I'm not sure why you would expect the two to match. I don't login to my mac with [email protected], I don't expect to login to my Windows laptop with [email protected] either.
The searching I can only surmise you were doing it wrong? I've never had an issue searching by first or last name in any tool whether it be the AD tools themselves or Outlook.
AD is a directory server, it can service a Windows environment or a Mac environment or a Linux environment. They've got a complete implementation of LDAP if you choose not to use AD auth on the client side. That being said: EVERYONE integrates with AD. Very few people integrate with anything else. I like having unified auth in my environment, perhaps you enjoy managing local hosts but that sounds disgusting to me.
That all has to be replaced. That's billions upon billions in lost productivity.
Yup...over time, just like it is ALREADY replaced over time. But let's assume I accept everything you stated without quibble.
I feel like we've lost the point of this thread. Yes, ANY large company vanishing would have a large impact. The more widespread the current influence of that company, the larger the impact.
But we weren't discussing "does MS qualify as a company with widespread influence". We weren't saying "I bet I can name a large company that could vanish without notable impact". Someone made the assertion that Amazon is somewhat unique in the results of theoretical vanishing. Even if Amazon ISN'T unique in this regard, the consequences of Amazon vanishing and MS vanishing are very, very different.
Windows Server -- RHEL
MS SQL server -- PostgreSQL
SharePoint -- let it die, useless
Office -- LibreOffice, Google Apps
If MS stopped supporting their products it would be literally billions of collective dollars to migrate to alternatives.
I've been doing this a long time and in my personal observations I've noticed my corporate and (especially) government customers have been moving more into the Microsoft ecosystem than 10 years ago. MS is more important than they've ever been, if you can believe it.
Except for the Server OS. That's already built to be pretty standalone (aside from updates and collaborating with other Windows Servers). The idea here is that future security vulnerabilities aren't being patched which means it'd be open season for hackers once new vulns are discovered.
...and I'm desperately trying to hold in comments about the small difference in performance between 1980s and MS software - I honestly blame Outlook for how the world killed email as an effective medium.
Though I do count myself lucky to have my current job. I've worked public sector in the past, and recently started up a 2nd (part time) job at a university that involves using Outlook. It is quite painful.
If they were to suddenly go legs up today that would have unimagionable consequences. The size of their offerings and the amount of companies using their stack is breathtaking. Sure, except for their online services the stack would still be there, but the prospects of no more security updates would cause real problems and a slow but steady meltdown.
There would be scrambling like we have never seen before in the IT world. So much scrambling.
