Using FASP protocol to accelerate near time secured data movement for database replication.

This article centers around database replication over large distances. One of the key issues is to transfer data securely over long distance without compromising on the speed of local replication. This article tries to address the issue by proposing a innovative approach to transfer data at high speed using available bandwidth including delivering into cloud targets. All these by not affecting any other application using the same network.

There is a topology that replication products support which can be termed as manual log shipping. In this topology database logs are ftp-ed to another location where replication agents are running. There are many manual steps that are involved in this method. Also error prone when done over a long distance. On top of this user has to secure the transfer of the database logs. The advantages of this article is that it will eliminate all of the shortcomings described before with the current technology. File transfer will be very fast using FASP protocol and replication can achieve near real time speed in the proposed configuration even in manual log shipping topology

Aspera is a product which specializes in high speed file transfer over internet. It uses FASP. Unlike TCP, FASP throughput is independent of network delay and robust to extreme packet loss. FASP transfer times are as fast as possible (up to 1,000x standard FTP) and highly predictable, regardless of network conditions. The maximum transfer speed is limited only by the resources of the endpoint computers (typically disk throughput). The FASP protocol does not compromise transfer speed. It is based on open standards cryptography, it provides SSH end-point authentication, on-the-fly data encryption (where we can also store files encrypted on the receiver's end), and data integrity verification. With all these it claims that speed would be same.

Database replication products reads the backup log files generated by the source database and reconstructs the transactions and send them over the wire to a target datastore. One of the topologies of the DB replication products is to copy the backup log files to another location where replication engine is running. This is practical over a short distance. When it comes to long distance near real time replication, securely and reliably sending the log files becomes an issue. For example, sending the log files from on premise datacenter to soft layer maintained cloud system.
