Cloud computing takes shape


AS CLOUD TECHNOLOGY MATURES, THE OPTIONS FOR HPC USERS CONTINUE TO EXPAND, WRITES ROBERT ROE


HPC users are increasingly turning to cloud technologies due to their flexibility and scalability,


allowing them to quickly change the size of their workloads, adopt new technologies in a small testing environment and to help to increase the agility of a company working across multiple sites, or even countries. However, there are many different

options from managed services to on- premise cloud installations and hybrid approaches, which each offer their own benefits to different user groups. A recent survey carried out by Ansys and Digital Engineering aimed to identify best practices and insight into the type of cloud technologies being adopted by HPC and simulation users. The survey found that the cloud is beginning to take hold of the simulation user landscape. For example, 17 per cent of respondents are currently using the cloud and another 20 per cent plan to do so within 12 months. ‘The growing need for cloud options is fuelled by the trend of users increasing the size of their simulations. These large simulations require more high- performance computing and data storage resources,’ states Wim Slagter, director for


HPC and Cloud Alliances at Ansys. The survey notes that more than a third


of users reach peak computing capacity a few times per month. When these moments occur, users can access cloud resources to meet the need for additional storage and HPC. Respondents were requested to note if


they worked for a large, medium or small company. Based on those responses, 42 per cent of those that are already using the cloud for simulation purposes are
