PDC Cloud services

Computation

The PDC Cloud features 8TB of memory and over a thousand physical CPU cores that can be utilised as an even larger number of virtual CPUs through virtual machines. The VMs in the PDC Cloud are hosted on servers that have AMD EPYC 7713 processors. These servers run the hypervisor software which creates and runs the VMs in the PDC Cloud. These hypervisor machines are interconnected to each other via a network with a top speed of 100 Gbps and are also connected to the KTH campus network with the same speed.

Researchers will be able to choose to use various types of VMs that will feature different numbers of CPU cores and different memory capacities to suit a range of diverse computational needs. This will enable researchers and other service providers to deploy their services in a robust environment. (Some examples of such types of services include Jupyter Notebook services for training, database services and data analytics workflow services.) People who use the PDC Cloud will also be able to benefit from a concept called floating IPs (a type of virtual IP address) to make their portals and web services publicly available to other users.

Data storage

  • The PDC Cloud platform includes a large-scale object store based on Ceph (a highly scalable open-source software-defined storage solution designed to address today’s high-growth storage requirements).
  • The initial gross capacity of this storage is slightly above 1 PB, and the capacity is likely to be extended in the future.
  • This object store will initially be made available via an S3 interface.
  • It is easy to access the PDC Cloud as new users do not have to create an account on the cloud if they already have a virtual identity, such as a SWAMID identity provided by the Swedish University Computer Network (SUNET). The underlying Ceph technology supports identity authentication mechanisms which can be integrated with various virtual identity providers.

Other services

  • user support
  • information about project quotas

Note that there is a wide range of possible services that may be included in the PDC Cloud services catalogue in the future, such as a container orchestration platform, high availability services, load balancing and big data analytics.
