Multus: how to escape the Kubernetes eth0 prison

Kubernetes has been successful for a number of reasons, not the least of which is that it takes care of things that application developers may not want to bother with – such as, for example, networking. Multus is a feature that can be used on top of Kubernetes to enable complex networking use cases.

Hybrid cloud and multi-cloud: what is the difference?

Hybrid cloud and multi-cloud are two exclusive terms that are often confused. While the hybrid cloud represents a model for extending private cloud infrastructure with one of the existing public clouds, a multi-cloud refers to an environment where multiple clouds are used at the same time, regardless of their type. Thus, while the hybrid cloud represents a very specific use case, multi-cloud is a more generic term and usually better reflects reality.

Ubuntu on WSL 2 Is Generally Available

Today Microsoft announced the general availability of Windows Subsystem for Linux 2 in the Windows 10 May 2020 update. WSL 2 is based on a new architecture that provides full Linux binary application compatibility and improved performance. WSL 2 is powered by a real Linux kernel in a lightweight virtual machine that boots in under two seconds. WSL 2 is the best way to experience Ubuntu on WSL.

ZFS focus on Ubuntu 20.04 LTS: what's new?

Ubuntu has supported ZFS as an option for some time. In 19.10, we introduced experimental support on the desktop. As explained, having a ZFS on root option on our desktop was only a first step in what we want to achieve by adopting this combined file system and logical volume manager. I strongly suggest you read the 2 blog posts, linked above, as introductions to this blog series we are starting. Here we cover what’s new compared to 19.10 in term of installation and general features.

Kubernetes for Data Science: meet Kubeflow

Data science has exploded as a practice in the past decade and has become an undisputed driver of innovation. The forcing factors behind the rising interest in Machine Learning, a not so new concept, have consolidated and created an unparalleled capacity for Deep Learning, a subset of Artificial Neural Networks with many “hidden layers”, to thrive in the years to come.

Kubernetes on Windows with MicroK8s and WSL 2

Kubernetes has enjoyed an unparalleled 5-year growth that has revolutionised the IT industry. It has become a key factor for organisations to be successful and have a competitive advantage. In order to optimise these benefits, organisations look for new ways to reduce Kubernetes complexity and get interoperability with other systems. See how combining MicroK8s and WSL 2 brings a low-ops, fully conformant Kubernetes through a single-command install within Windows.

Kubernetes GitOps with Azure Arc and Charmed Kubernetes

This week, Canonical announced the integration of Charmed Kubernetes with Microsoft Azure Arc. This integration provides businesses with a centralised place to manage their Kubernetes clusters and deploy their applications at scale, from cloud to the edge. The Azure Arc dashboard enables management and governance of any Kubernetes, across any substrate.

Ubuntu 20.04 LTS to enforce stronger TLS v1.2 encryption by default

In Ubuntu 20.04 LTS, the OpenSSL 1.1.1f library has been modified to use Security Level 2 by default (previous versions of Ubuntu use Security Level 1). Security Level 2 guarantees that protocols, key exchange mechanisms, cipher suites, signature algorithms, certificates and key sizes provide a minimum of 112 bits of message secrecy. In practice, it means that RSA keys are required to be at least 2048 bits long and ECC keys at least 224 bits using the SHA256 certificate signature algorithm.

FIPS certification for Ubuntu 18.04 LTS

Canonical has received FIPS 140-2, Level 1 certification for cryptographic modules in Ubuntu 18.04 LTS, with FIPS-validated OpenSSL-1.1.1. modules included. This certification enables organisations to meet compliance requirements within the public sector, healthcare and finance industries when utilising Ubuntu 18.04 LTS within public and private cloud environments. Canonical worked with U.S. Government and BSI accredited laboratory, atsec information security, for the 18.04 LTS FIPS certification.
