The European Commission Is Testing an Open Source Alternative To Microsoft Teams (euractiv.com) 69

The European Commission is preparing to trial a communications platform built on Matrix, the open source messaging protocol already used by the French government, German healthcare providers and European armed forces, as a sovereign backup to Microsoft Teams.

Signal currently serves as the backup tool but has proven too inflexible for an organization the Commission's size, it said. The Matrix-based solution could also eventually connect the Commission to other EU bodies like the Parliament.

    The move away from MS crap. Not for the reason I expected, but still.

    The fatal mistake that Microsoft made was disable the email of the chief prosecutor at the International Court of Law. At that point, it became blatantly obvious and impossible to ignore that MS will do whatever the US administration wants to its international (and probably national) customers. The EU administration observed this event very carefully and drew its conclusions. Obviously, this will be a process over the next 5-10 years or so, but MS is cooked.

      What did it take to destroy Microsoft?
      Corpocracy + fascism + consistently bad US foreign policy.
      Sort of a perfect storm that turns what probably seemed like a sweet deal for the big tech companies into a nightmare scenario of break up. I bet they wish they still had Biden and the Dems in power, that let corporate interests run much of the government as long as they had diversity policies.

      Can the EU actually pull this off? There are some tools that MS has, which nobody else has:

      1: AD/Entra. Maybe in the past, we had directory services and policy object servers that could scale up and out, but right now, AFAIK (and please correct me) AD/Entra are the only game in town if you have millions of users and need to handle AAA (authentication, authorization, auditing), of users, machines, and other objects, with GPOs and other policies attached. Yes, there is FreeIPA/IdM, and it works well, with replication, performance, and security. I'd assert it has a smaller attack profile than AD. However, it doesn't scale as well as AD can. AD can figure out how to replicate itself, and handle all kinds of oddball conditions.

      Note, this can't be a cloud service. Ideally, authentication should either be on-prem, or at least hybrid, so even without network connectivity, people can log into their machines and do offline work, even if caching isn't doable.

      2: A unified file sharing protocol. NFS v3 doesn't cut it for users. NFS v4 takes a well tuned environment to work. S3 is awesome for objects, but definitely not something you want to use as a VM storage backend. We need to have a protocol that allows for file sharing with the robustness of S3, but have additional commands for block I/O, so that can be as fast as possible. This would allow for things like versioning, object immutability, maybe even tiers of compression and encryption. However, as it stands now, SMB/CIFS is king, with nothing really dethroning it.

      3: Something to replace Outlook/Exchange. A standardized mail, calendaring suite that has all the C-level features needed. This can be hard, as there are a lot of systems out there (Google WorkSpace, Zimbra, Zoho)... but feature-wise and usability-wise, MS comes out ahead, if only because people are familiar with it, and it does well enough.

      4: SharePoint. Don't laugh, but SharePoint and Confluence are unique programs. There are other Wiki programs that can do the job, but the ability to import things in and make workflows happen make those two commercial programs extremely useful, especially in maintaining documentation.

      5: GitHub/GHE. If I have a F/OSS project, and forget about it, I am pretty much certain that 5-10 years from now, it will still be there and usable, perhaps someone finds it, forks it and makes it useful again. Other Git systems... not so much, and when stuff vanishes, that is history lost forever. This needs to have government support, and some sanity (so this doesn't get turned into someone's personal multi-terabyte storage of videos). Maybe more space if people "adopt" it. It also needs to span countries, just so if something happens in Europe, that source code would be available in the US.

      6: MDM/RMM tools. Intune has its issues, but the Holy Grail would be something that could manage Macs, Windows machines, and many Linux distributions, as well as iOS, and Android devices. This would be both cloud based as well as available on-prem. This functionality is critical to a business's operations, and needs to be integrated into the OS. Ideally, for Linux, some parameter which can be inputted at install time to have the installer pause, go to a URL, pull code from there and then function like Autopilot or Apple's ABM provisioning.

      7: I hate to mention this, but an IRM. Something like MS Purview. DRM is ugly, but in this case, it can be the one thing that is the difference between exfiltration or no.

      8: A VDI cloud connection broker, as well as a VDI system. Otherwise, you are paying for Omnissa, Microsoft W365 or AVD, Citrix, or something else, and those are not cheap. Having a VDI system that is inexpensive and works well with Proxmox can bring a critical security tier to a company.

      9: Don't laugh... a GPG keyserver combined with transparant GPG in mail apps and webmail. We have moved away from tried and true encryption to stuff based on "trust me". Enough. We need to see about going back to the GPG standard.

      Getting rid of Teams is a positive, but to break MS's iron grip, there are a lot of other basic enterprise items which need to be made into vetted, maintained, open source projects.

      • I wonder if a country could just pass a law saying that from 1 year ahead all SW in public administration must be Open Source, as public transparentcy ought to demand anyway. I bet that it is far less trouble and loss compared to the trouble keeping especially MS around. If there is no way back, I am sure they will handle it, but if they keep MS as a fallback, nothing happens, because all the MS centric IT people will block it.

          Though I agree, in principal at least, some past attempts at requiring open source had lead to various "source available" licenses that are still proprietary. It can be an easy way for them to keep their foothold where needed, and mostly defeats the purpose of the open source requirement.

          Teams and XBox are the things that are keeping people using their Microsoft accounts. Teams has alternatives, like Jitsi and Matrix, but they are not interoperable with Teams. Microsoft Office is also something people cling to, even though LibreOffice can do the same, better, and without requiring any retraining.

          Matrix has the ability to hook in compatibility with Teams but it's paid. If the rest of the world (other than the US) is already switching to something Open Source and better, why not just switch with them?

      You may have overlooked that in Europe, both the overall administration and member states sponsor FOSS projects. You may also have overlooked that there are quite a few businesses maintaining and developing FOSS in Europe. The European Commission can get whatever is missing developed for them and make that FOSS as well. And they probably will and then anybody can use it.

      Incidentally, I used a teaching video conference platform from an EU project some 20 years ago. The only thing was that it needed more bandwidth that was readily available in those days, so they used a complex TCP tunneling set-up for their tests that required scheduling 2 weeks in advance. My site just went with the ample bandwidth we had over regular Internet (10Mbps at that time) on the 2nd test and this all worked really well, including features like shared whiteboards, camera-switches, user cameras and voice, integrated quick test mechanisms, etc. And the bandwidth restrictions are not an issue anymore today.

      Bottom line, it is not that hard to make a good video-conferencing tool. It does not need any kind of secret engineering or big magic. All it needed was bandwidth for the regular user to get to a reasonable level. And we have that now.

    If they are looking for a chat app, then they may have success.
    If they are looking for an integrated app in corporate groupware then they will fail miserably. As long as they don't side by side compare features such as Sharepoint integration, Outlook integration, the selection of commercially available meeting room hardware, etc. they may stand a chance, otherwise Teams offers a feature set that has no comparison with anything else.

    I'd amazing that people are pitching the creation and integration of a Teams alternative as some mammoth task that only Microsoft can pull off, and attempts by anyone to compete will fail. You should keep in mind the fact that the US is not the sole source of IT expertise on earth, and the EU is more than capable of taking them on. The EU has the ability to pass legislation that can compel Microsoft to co-operate, and access to the necessary skillset is certainly available. The world has seen how broken the US has become recently, and there is no debate that the US will leverage its access to US companies to force outcomes that meet their need - they are in reality no different to China or Russia in that area. Recent development such as the arbitrary and unbalanced tariffs, invading foreign countries and threatening to annex sovereign territories shows that the US are no longer the 'good guys' but are slowly descending into a mess approaching that of other dictatorships around the world. There is every reason for nation states and blocks like the EU to invest in technology that serves their interests over those of the US. The fact that this is being discussed publicly shows that this is not a random thought bubble but rather a signal from people more than capable of competing with Microsoft on this. The idea that a nation state competitor to Teams is not possible is a joke.

      The obstacle to replacing Microsoft will not be the code, it will be the necessity of ensuring every country gets their participation, gets their say, that every special interest gets served, that everyone has a piece of whatever is created.

    As a Linux user, all microsoft products are crap. Teams is just another example. In theory, they ported it everywhere, and it's not much better on Windows, but the most basic things about their systems are completely disfunctional, particularly on Linux. People continually send me teams invites and there are problems with authentication, it asks me to log in and then i have to go out and click in again. Sharing documents, well of course that's word, and office 365 isn't the same as office on Windows, which isn't the same as Office on mac. Microsoft can't even make their flagship components work seamlessly for paying customers across platforms, so aside from political issues, I just don't understand why anyone enjoys using their garbage. I know that for a single user, Word was better than Libreoffice, and certainly has more features than Google docs. But we have other needs now, like editing in a team, and their advantages in formatting are nothing compared to their inability to just create a single coherent, compatible product that interoperates with itself. I know I wrote more in this post about office, because I've had such horrible recent dealings with it, I just have blanked out the memory of my problem with teams, but it definitely sucks. I think the only way it will ever get better is if they start to lose the monopoly and are forced to actually deliver value. But since Microsoft culture has never been about that, they simply bought companies who had developed Word, Excel, etc. the question is, can they develop a culture of fixing their broken garbage? I don't think so. They are too big and too dysfunctional. They just want to keep adding paperclips, AI advisors, and focus on stealing my data rather than providing a decent tool to work with.
