摘要
如今,随着云计算的发展,各类企事业单位逐步开始利用云计算技术提供业务、数据等托管服务,通过基于互联网的“托管”及“租用”的模式解决企业数据库基础设施建设的问题,以降低数据库部署、容灾等运维成本。文中主要从混合云环境下多租户数据库实际业务需求以及数据保护的角度,阐述了通过混合云资源池多租户数据库RAC(Real Application Clusters)+DG(Data Guard)的数据库容灾模式,可大大提升混合云资源池多租户数据库服务的可靠性及连续性,从而数据库即服务(DBaaS)的高可用性得到充分体现。
Nowadays,with the development of cloud computing,various enterprises and institutions are gradually using cloud computing technology to provide business,data,and other hosting services.They are solving the problems of enterprise database infrastructure construction through Internet based"hosting"and"leasing"models to reduce database deployment,disaster recovery,and other operation and maintenance costs.From the perspective of the actual business requirements and data protection of multi tenant databases in a hybrid cloud environment,this article expounds that the database DBRA model of RAC(Real Application Clusters)+DG(Data Guard)for hybrid cloud resource pool multi tenant databases can greatly improve the reliability and continuity of hybrid cloud resource pool multi tenant database services,and fully reflect the high availability of database as a service(DBaaS).
