A large state corporation in Brazil is currently trialing 800 Linux PCs. If successful, it will deploy and replace 22k Windows installs, comparable to the migration happening in Germany.
Companies that use Windows and Azure are locked into it by their use of things like AD, Intune, Exchange, OneCloud, SharePoint, Hello etc., on the infrastructure and ops administrative side, not necessarily by Office365. It's almost impossible to make a clean break from all that for any company past a certain size.
History tells us that 85% of these people will move to Windows 11 despite what they say.
The interesting rub this time is the hardware. There's tons of still powerful and useful CPU's in use today that don't support Windows 11's TPM 2.0, so I wonder if that will push a few more people to Linux than when Windows 7 was EOL.
Google workspace has a fraction of the functionality. At a base level they're relatively comparable. But once you go into more advanced functionality and security, 365 is a landslide better.
In terms of the basic office utilities like text editor, spreadsheets and so on, Google is a good contender. But Google Workspace isn't even close to the functionality IT admins have with Microsoft Defender, Intune, Entra, Purview, and so on.
There's a lot more going on at the administration side than just the user's experience, that could make it less ideal to move to Linux.
I'm saying this as someone who hates both Microsoft and Google.
I'm work in IT as a support specialist that manages computers for about 30-40 people and we don't even use those tools like Defender, Intune, etc. We can definitely make the switch from Windows to Linux. It's not impossible, especially when you have someone in your company who knows enough on how to self-host and use Linux efficiently.
My boss and I are working on moving to Coreboot on our machines. We have a bunch of older computers that support it (e.g. Dell Optiplex 9020/9010/7020/7010), they all support Coreboot/Libreboot firmware so not only will we save on hardware costs, we are moving towards using Proxmox VE with Kicksecure on all of our employees computers.
I also want to setup Nextcloud for file storing and self hosting for OnlyOffice. We can also move toward Bitwarden, we unfortunately still are using LastPass. I would also like to replace our routers/switches with those that can run on OpenWRT.
We only have about at most 30-40 computers total operating total at both of our locations. I figure why not? My boss is giving me a chance to apply these skills and I'm hoping we can just start moving away from anything that requires a subscription. We can save so much money.
