twentieth of this. Also implied is that more and more functionality is migrating from the nodes' infrastructure to the Kubernetes level and that the system's software can become dumber in return. Talos ... In the world of container virtualization, the operating systems of compute nodes are largely degraded to non-player characters that can do little more than start and stop containers.

DigitalOcean has announced a major update to its DigitalOcean Kubernetes Service (DOKS), which now allows organizations to scale up to 1,000 nodes per cluster. Key features of DOKS include

the Kubernetes node manages and loop mounts in the container. Block storage PVs are faster, especially for write access, because they use the filesystem cache of the local node but do not support read

you store, manage, and retrieve data in your applications. The database currently supports 14 programming languages – C, C++, C#, Go, Java, Kotlin, Node.js, PHP, Python, Ruby, Rust, Scala, Swift

laboratories, and commercial environments. It is easy to use, has great flexibility, and is stateless (no installation on a drive in each node). You can use it to boot groups of nodes with a particular

Traditional enterprise virtualization clusters run on physical servers, on which Kubernetes clusters, whose nodes run on virtual machines (VMs), are then based. This kind of architecture is fraught
