But instead of working with the IT team to expand systems when needed, the DBA is responsible for adjusting the cloud service tiers with the DBaaS vendor to accommodate required capacity growth. A DBA continues to work with application developers and end users to forecast system usage and resource requirements. For critical security and system availability updates, the vendor often sets strict deadlines that require them to be done by a specific date and then applies the patches itself, instead of the DBA doing that. The DBaaS vendor defines maintenance windows, although a DBA can adjust dates and times for regular maintenance as needed. The vendor handles configuration and execution tasks, while the DBA is responsible for adjusting the backup routines and schedule to meet application needs. That becomes a shared responsibility with the DBaaS vendor in the cloud. In on-premises systems, a DBA is responsible for data backup, recovery and retention processes. That requires the DBA to learn the chosen DBaaS vendor's disaster recovery architecture. Another shared responsibility on premises, it typically falls on a cloud DBA to ensure that geo-replicated backups and geo-redundant database system clusters are set up and configured as needed. #DATABASE ADMINISTRATOR FULL#But in the cloud, a DBA often assumes full responsibility for working with the vendor to provision the database system and allocate compute, memory and storage resources to workloads. Initial system design and resource allocation responsibilities are commonly shared with other IT staffers in on-premises environments. Here's an overview of some of the changes that DBAs can expect when they begin administering DBaaS environments. Typically, they also must take on some new duties and responsibilities in place of existing ones that they no longer need to do. But it does decrease the routine administrative work that's required.ĭBAs who shift from managing on-premises database systems to cloud-based ones need to be trained on the new architectures. Migrating to a DBaaS environment in the cloud doesn't reduce the amount of time a DBA spends administering the back-end system to zero. Managing databases in a hybrid cloud: 8 key considerationsĪ mistake that some IT and data management teams make is assuming that DBaaS vendors provide the vast majority of database administration functions - or all of them, even. #DATABASE ADMINISTRATOR HOW TO#
