Answer to question: What are the best options for High-Avaliability and Disaster Recovery? Is it possible to move data from one datacenter to another and how is data transferred? Are there any numbers about the speed of data replication between two datacenters and consistency of the process?

You can use replication for HA across Elastic Clusters or Single-Server instances. For example, nearly-instantaneous Transactional Replication is used by some of our larger customers (e.g., Globo of Brazil used a Transactional Replication setup for the entire World Cup 2014 without any issues).
Replication, using a variety of topologies, can be used to achieve High-Availability via a collection of Single-Server instances. If need be, you can go further using a Shared-Nothing Cluster Configuration comprising a horizontally partitioned database spread across commodity server machines.
