A brief history of MicroStack

=> ↺ A brief history of MicroStack

OpenStack is no doubt a wonderful and successful piece of software. It allows you to create your own cloud infrastructure, and thanks to its open-source nature, it’s free to use for everyone. But as with many giant software projects, all that power comes with a challenge: it is reasonably complex to install and configure. A number of OpenStack distributions do exist that intend to make engineers’ life a lot easier, but those also tend to be more complex than a non-experienced user would like them to be.

To solve this problem once and for all, Canonical created a simplified and easy-to-install distribution of OpenStack called MicroStack.

- Detect EFI boot variables with hexadecimal digits, not only

  decimal digits.

• hw-detect:

- Restore support for firmware license prompts (#1033921).

  footprint (#1033301).

  exabyte (EB), and exbibyte (EiB).

- With many thanks to Vincent Danjean!

  the hostname parameter on the kernel command line as a fallback

Confidential computing use cases [Ed: IBM/Red Hat pushing data breach (outsourcing) as privacy or "confidential computing"]

=> ↺ Confidential computing use cases

This article is the third in a six-part series (see our previous blog), where we present various usage models for confidential computing, a set of technologies designed to protect data in use—for example using memory encryption—and the requirements to get the expected security and trust benefits from t​​he technology.

In this third article, we consider the four most important use cases for confidential computing: confidential virtual machines, confidential workloads, confidential containers and confidential clusters. This will allow us to better understand the trade-offs between the various approaches, and how this impacts the implementation of attestation.
