A lot of DBAs aren’t as familiar with Oracle DataGuard as many would think. Even though it’s a phenomenal product, they may have never used it, so knowing the ins and outs of the best Oracle product to use with Oracle on Azure is important.
I highly recommend the following documentation and guidelines from Oracle. The Product team in charge of DataGuard is fantastic at Oracle, so why go anywhere else to learn about this?
If you are in the situation where you’re thinking about moving your Oracle servers to Azure, this is a good starting point.
