Description
Currently major cloud providers provide cold storage services as a part of their public IaaS offerings, targeting users who need to store data with relatively low access frequency for long periods. The adoption of cold storage services should be considered in order to reduce the total cost of ownership and the labor of storage management of maintaining large amounts of scientific research data over a long period of time. However, performance and cost of public cold storage services in scientific applications have not been well studied, and the following issues arise:
- It is difficult to determine whether cold storage services meet the performance requirements of research applications.
- It is also difficult to assess the feasibility of storing and accessing research data in cold storage services in terms of cost.
- We can obtain practically acceptable performance of data access in the cold storage services by configuring the archive system with appropriate sizing of instances and tuning the system. Although some cold storage services require hours to start data access, this disadvantage can be mitigated by adopting an appropriate tiered storage architecture.
- The proposed cost estimation model enables to estimate total cost of data archive in the cloud cold storage services and data analysis on the cloud services. The model is also capable to estimate cost on a hybrid system organized by clouds and on-premise systems. Additionally, the practical information which can be used to determine the optimal configuration of the analysis system such as sizing information of AWS instances are acquired.
