Research Computing Services

Dependant on the type of research workload that must be carried out, different flavours (instance types) of virtual machine can be created and operated by research groups. Usage of these flavours would be charged at different rates for the duration of their life-time and broadly these flavours fall into compute and memory-focused categories. 

Please note that the minimum commitment when purchasing resources is 1 year. Resources can be also purchased with 3 and 5 year commitment.

Please also note that this page does not describe pricing for the main HPC Service , the prices for which can be found here.

Compute-focused flavours (Instance Types)

Usage cases: Scientific modelling & analytics, batch processing, virtual laboratories, scientific web applications/web servers and data warehouses.

Storage

Default backing storage for an instance root volume is co-located on the hypervisor RAID1+0 SSD array. This provides for low-latency access to hypervisor-local storage for instance root disks, at the penalty of reduced total storage capacity and added difficulty migrating instance root disks from a hypervisor.

An alternative where larger, but higher latency instance root storage is required is to boot an instance to network storage provided by a large Ceph cluster. Additional block volumes or object storage from the same Ceph cluster can be attached or detached from a compute instance as needed.

Storage type Cost per TB/Month Cost per TB/Year
Block storage £12.00 £144
Object storage £12.00 £144
