The author envisions some impacts of cloud computing on the BI software industry:
- easier evaluation (nothing to download, no machine / space / skills required to install, no configuration, nothing to uninstall)
- more short-term ad-hoc analysis
- more BI projects because funding is easier and less resources required
- extension of data warehouse projects to medium size companies
- analytic SaaS market will grow quickly
Well, maybe it won't be so easy, it will be interesting to track real projects going in this direction and how they succeed/fail.
Obviously this "BI over the cloud" requires a new kind of database technology (database column is linked with Vertica):
- Share-nothing architecture, to quickly asborb peaks in on-demand analysis.
- Aggressive data compression to reduce storage costs. ==> Agreed, but what about performance?
- Automatic grid replication and failover ==> The cloud must prove it is at least as robust as an internal installation.
