Canonical Launches MicroCloud To Deploy Your Own "Fully Functional Cloud In Minutes"

[Yalok]

So much talk about how easy it is to setup MicroCloud and nothing about what it really offers.

I would like to see Cockpit packaged as a Snap so that you can install it on Ubuntu Core (which only supports snaps, not .deb packages).

I would also like to see a way to remotely via web browser manage Snap packages on a Ubuntu server.

Michael And if this thread turned out to news how about the real ones:

https://thehackernews.com/2023/11/researchers-find-34-windows-drivers.html

As many as 34 unique vulnerable Windows Driver Model (WDM) and Windows Driver Frameworks (WDF) drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems.

Of the 34 drivers, six allow kernel memory access that can be abused to elevate privilege and defeat security solutions. Twelve of the drivers could be exploited to subvert security mechanisms like kernel address space layout randomization (KASLR).

It turns out this Windows 'hybrid' (not hybrind enough I think..) kernel is nothing, but marketing joke.

L[/URL]inux process scheduler has been bugged since forever: https://thehftguy.com/2023/11/14/the...arly-20-years/

There's nothing like blindly pasting nonsense:

https://lore.kernel.org/all/[email protected]/

The important note here is that this limit is about timescales, not anything else. Previously a 64 cpu system would blow up the latency to 6ms * (1 + ln)2(64)) = 42ms, which is atrocious.

It's not a bug, it's a feature (and no sarcasm here).

MicroCloud looks interesting:

• it is open source: https://github.com/canonical/microcloud
• it is available on snap for free, you do not need a Pro account
• it is not based on kubernetes, which to me is a big selling point

That last "news" from the HFT Guy is pure click bate. It's not a bug, that's just how the scaling factor is calculated. It is not a cpu limit.

The latest software offering announced today by Canonical with an enterprise focus and their hopes of driving new Ubuntu Pro and support subscriptions is MicroCloud.

It looks like the bottom tier subscription is annually $25 dollars. I wish more Linux distributions considered such reasonable pricing to increase their revenue.

"fully functional cloud in minutes"

is that what they call snap startup times?

That's a limit of LXD. LXD is like Kubernetes. LXD is built around running containers on LXC. LXC, if you're not aware, is a container runtime similar to Docker.

Scaling beyond 50ish nodes has been challenging for many projects. Around that number, internode communication can get tricky, as well as managing state in the control plane. Cassandra struggled (since fixed), Kubernetes struggled (since fixed), and Kafka is still capped at 50.

Yes. Originally the it said "50 minutes" (it got corrected afterwards), that's what I was wondering about. 50 machines makes perfect sense.
