0:00.0	AI might be the most important innovation ever. It's storming every industry with literally billions being invested, so buckle up.
0:07.9	The problem is that AI needs the right data and a lot of speed and processing power, so how do you compete without cost spiraling out of control?
0:15.7	Time to upgrade to the next generation of the cloud, Oracle Cloud Infrastructure or OCI.
0:21.4	OCI is a single platform for your infrastructure, database and application development, with AI
0:26.4	embedded across it all. And Oracle's offering cloud helps you address your requirements for location,
0:31.4	access and data residency. OCI provides blazing fast speeds for AI's demanding workloads,
