The CLIMB project provides a cloud computing infrastructure for microbial bioinformatics in the UK. Funded by the MRC, CLIMB offers large-scale data storage, computing capacity, and training resources to help UK microbiologists analyze the large amounts of data generated from next-generation sequencing. Currently 199 user groups actively use CLIMB's distributed computing clusters, storage, and customized Galaxy platform. CLIMB aims to meet the growing bioinformatics needs of microbiologists through its on-demand, scalable resources.
