The benefits of application of high performance computing (HPC) on cloud is undeniable. HPC on cloud not only gives organisations agility but also flexibility and scalability. However, while many agrees that HPC on cloud is the future HPC application, some organisations are still reluctant in its implementation due to misconception on various issues in adopting HPC on cloud such as cost and security . This post explores every challenge to change organisations view on why they should leverage the benefits by getting started with HPC on cloud.
According to a market survey conducted by a third party for AWS, many organisations are hesitant in running HPC on cloud due to the cost and cost-management. While the concern is relevant, organisations should understand that the implementation of HPC on-premises is also costly. With issues such as overutilised system where demand for on-premise HPC resources frequently exceed capacity, HPC on-premise leads to lost productivity. In addition, HPC on-premise requires organisations to invest on a more advanced hardware as the technology advances. On the contrary, HPC on cloud helps organisations to cut cost on purchasing and support on-premises servers for pre- and post-processing service. Moreover, once data is stored in the cloud, innate workflow advantages further lower the cost. Therefore, in reality, HPC on cloud is a better choice in cost saving department as it allows users who are unable to invest the upfront capital and effort to acquire on-premises infrastructure to leverage the use of HPC.
Security will always be a challenge when dealing with data. Thus, cloud security concerns are nothing new. HPC on-premise is undeniably advantageous over HPC on cloud in term of security and privacy benefits. However, the advantage cannot distinguish aging infrastructure issues that leads to the increase in the security costs of maintaining compliance. HPC on cloud, on other hand, is managed by the providers, where continuous system updates based on the latest technology is their main process. Today, leading cloud-based providers had come up with various security measures (Role-based access control (RBAC) to firewalls and private networks).
In summary, every adoption of new technologies and application come with challenges especially at the beginning stage. Misconception on certain implementation may hinder the growth of an organisation. Therefore, it is important for organisation to better understand the challenges in order to know whether an implementation is worthwhile.
