Abstract
Migrating from Grid to Cloud: Case Study from GEO Grid

On 11 March 2011 Japan suffered a major earthquake and resulting tsunami that caused great loss of life and devastated many buildings, industries, and information services. Recent flooding in Thailand has resulted in destruction of property and a disruption of services. Thus, it is prudent for information technology infrastructure and services providers to formulate and implement procedures for rapid disaster recovery of key services which become even more critical during catastrophic events. GEO Grid is aiming at providing a Cyber Infrastructure which provides federated access to Earth observation data and related services for Earth sciences. Designed and implemented using Grid technology, GEO Grid provided services such as satellite data services and application services such as disaster mitigation and monitoring for end users. Through the operation of GEO Grid, we could prove that GEO Grid was secure and stable as a Cyber Infrastructure for Earth sciences. However, we decided to migrate from Grid-based implementation to Cloud-like implementation based on the insights gained through our experiences on GEO Grid. This talk presents the overview of GEO Grid followed by the motivation of, and experiences on migration from Grid to Cloud.
