DB2MMT: A massive multi-tenant database platform for cloud computing

DB2MMT is a massive multi-tenant database platform for ISVs and Service Providers to gain business agility and maturity, to reduce time to market, to reduce CAPEX and OPEX and to provide competitive price for end users. This paper introduces isolation model, each model's security, scalability, SLA and these models' performance comparison, then introduces DB2MMT high level architecture and key technical challenges addressed, including resource, tenant and offering management, monitor, scalability and security. Experiments based on RUB is application which compared the economics of DB2MMT versus traditional solution with precise data showed acceptable performance, it also proved that fine grained multi tenant model provided by DB2MMT has significant economy advantage. © 2011 IEEE.
