Ubicloud is an open, free, and portable cloud. Think of it as an open alternative to cloud providers, like what Linux is to proprietary operating systems.

It's amazing how benchmarking a PostgreSQL change led to discovering an SSH compromising backdoor.
Makes you wonder how many developers in the world have the skills and stamina to investigate an issue end-to-end these days.

AWS popularized Arm-based CPUs with their Graviton line. When compared to x86, this new CPU architecture offers better price / performance and uses up to 60% less power.
We expected that enabling a new CPU architecture on Ubicloud would be tricky. We were pleasantly surprised

AWS, Azure, and GCP load balancers don’t support random as a load balancing (LB) algorithm. If you’re into distributed systems, ever wondered why?
After all, random is the simplest stateless way to distribute load across VMs/containers.

There are two ways to build elastic load balancers in the cloud today. You (a) take a solution like HAProxy and put it inside a VM or (b) reprogram your existing network plane to do load balancing.

One of Ubicloud’s networking features is firewalls. We wrote a blog post to describe how we implemented this using the Linux kernel’s Netfilter / Nftables subsystems.

The EU's new Data Act requires cloud providers to eliminate all switching costs (data egress fees) by Jan 2027. It also imposes requirements for cloud portability.

Our favorite Hacker News post of the day - "Llama 3 8B is almost as good as Wizard 2 8x22B (140B parameters)"
It's amazing how well small models can do if they are trained for a long time. If true, your GPUs with small VRAM can now go much further.

It’s for this reason that cloud load balancers support round-robin as a stateless load balancing algorithm. Sneak preview: Ubicloud network load balancers are live as of today and they support round_robin and hash_based LB algorithms.

We ran bunch of simulations to demonstrate this effect. For example, if you have a load balancer that serves 16 VMs, and your LB serves 2K requests, the most heavily loaded VM will serve 38% more traffic than the least heavily loaded VM.

This question came up as
@sahinffurkan
was designing Ubicloud's network load balancer.
Short answer: using random as an LB algorithm leads to a non-uniform load distribution across VMs.

This only makes sense. If you randomly assign requests to a large pool of VM/containers, one VM out of 16 will get lucky and won't have to serve as many requests. Another VM will get unlucky and receive more requests than all others. You’ll then need to plan your capacity for the
