SUSE has released the third prototype of their Adaptable Linux Platform (ALP), named “PIZ BERNINA”, which aims to continue the development of SUSE Linux Enterprise distribution. One of the key differences of the ALP is the separation of the distribution’s base into two parts: the “Host OS” for working on hardware, and a layer for supporting applications focused on launching in containers and virtual machines. The ALP is being developed using an open development process with intermediate assemblies and testing results publicly available.
The third prototype includes two separate branches that will develop in different areas of application and will differ in the services provided. A branch called “micro,” focused on constructing cloud systems and launching microservices, is available for testing. Ready assemblies for the X86_64 architecture are prepared, including “bedrock” and “micro.” Additionally, assembly scenarios are available for Aarch64, PPC64le, and S390x architectures.
The architecture of the ALP is based on the “Host OS” environment, which is minimized for support and control of equipment. All user-space applications and components are launched in separate containers or virtual machines, isolated from each other, allowing users to focus on applications and abstract work processes, separating them from the low-level systemic environment and hardware.
To achieve this, SUSE is using the Sle Micro product, which is based on the developments of the microos project, for their “Host OS.” They also offer pre-installed SALT configuration control systems and ANSIBLE for centralized management, as well as podman tools for launching insulated containers.
SUSE positions the ALP as a platform for confidential computing, which can help protect data and prevent interference from malicious actors. With the ALP’s focus on launching applications in isolated environments, SUSE hopes to continue to raise the level of security and privacy in computing.
