Scheduled downtime for the HPC2N region of SSC – 3/9 2018

One of the central network switches in the storage-infrastructure will be replaced due to a failed fan and to do this we must shut down all running instances in the HPC2N region on 3/9 2018 between 08:00 and 12:00.

This will only effect the HPC2N region and will not have any impact on instances running in the other SSC regions.

However login via the web dashboard to the other regions will not work during this maintenance period.

SNIC Science Cloud Workshop in Sundsvall, 31 August 2018

The SNIC Science Cloud (SSC) invites all interested current and future users to a training workshop on an introductory level at Mid Sweden University, Campus Sundsvall, 10:00-16:00 on the 31st of August.

We will introduce cloud computing in general, including covering the best practices around security and you will learn the basics of how to work with the OpenStack based Infrastructure-as-a-Service (IaaS). The majority of the time will be spent in lab sessions on basic usage of the IaaS cloud.
You need to bring a laptop, but no prior experience of using cloud resources are required.

Information Security Workshop

The work on SNIC Science Cloud is progressing rapidly. Today we are operating two fully functional regions (at HPC2N and C3SE), with capacity to host over 2000 VCPUs. That capacity will soon double with the addition of our third region provided by the UPPMAX centre.

As part of assessing the readiness of the project to start delivering production resources, we gathered last week for an Information Security Workshop organized by the SNIC office. It was two intensive days filled with interesting potential scenarios, and corresponding mitigation options.

One major outcome of the workshop was a more extensive list of topics that we need to carefully explain to the users of the IaaS systems, in a structured manner. This is important input that we will bring with us into the work on finalizing a draft service description for SSC, and a security guideline, that we are currently working on.

Using IPv6 with your instances

One prevalent problem for SSC has been a constant shortage of IPv4 addresses. Fortunately, it is now possible to use IPv6 with your instances. You can find a tutorial for how to enable the interfaces in your instances, and read about the requirements client-side to access instances over IPv6 here: https://github.com/SNICScienceCloud/technical-training/tree/master/how-to-use-IPv6
