The data in each protection group is replicated across six storage nodes. The distributed, low latency storage engine at the center of Amazon Aurora depends on AZs.Īmazon Aurora handles its storage volumes in 10 GB logical blocks called “protection groups”. Each AZ is isolated from the others, except for a low latency link that allows for rapid communication with the other AZs in the region. Instead of talking about SAN, DAS, fiber channel, connections, and so many other variables Amazon just wants you to think about AWS and now their Amazon Aurora.Īmazon Aurora storage engine is a distributed SAN that spans multiple AWS Availability Zones (AZs) in a region. The cloud solutions found this as an incentive to customers to avoid those large investments and complex platforms, and migrate these databases to the cloud. And we could be talking about platforms that insert hundreds of millions of new rows within a few hours, it’s easy to understand that we need a storage platform with high performance.
And also announced a short time ago, PostgreSQL compatibility (available as a preview).Īs any IT person would know, the storage design in any enterprise-scale platform for a database is going to be the backbone of the service that is providing. Amazon Aurora is promising up to five times better performance than MySQL with better security, availability, and reliability of a commercial database and a 10% cost of what organizations are paying. StarWind Virtual Tape Library (VTL) OEMĪmazon released recently the Aurora Storage Engine as a MySQL-compatible relational database service and is highly encouraging to customers to migrate from Oracle or Microsoft SQL Server to this new cloud service platform.
