Amazon slides first flash hardness into Redshift data muncher

SSD-backed compute nodes to cut query times on the mega data warehouse

Next gen security for virtualised datacentres

Amazon has added compute nodes with flash drives to its cloudy data warehouse Redshift – as the e-retailer turned computer-renter takes on Teradata, Greenplum, Oracle, IBM and the like.

The two "Dense Compute Nodes" were announced today by Bezos & Co: these are solid-state-drive-backed server options to sit alongside the disk-based Storage Nodes.

"The Dense Compute nodes feature a high ratio of CPU power, RAM, and I/O performance to storage, making them ideal hosts for data warehouses where high performance is essential," the web bazaar wrote in blog post.

"You can start small, with a single Large node for $0.25/hour, and scale all the way up to a cluster with thousands of cores, terabytes of RAM, and hundreds of terabytes of SSD storage."

The nodes are available in two formats: "Large", which comes with 160GB of SSD storage, two Intel Xeon E5-2670v2 virtual cores, and 15GB of RAM, and "Eight Extra Large" which has 2.56TB of SSD storage, 32 Intel Xeon E5-2670v2 virtual cores, and 244GB of RAM.

The company claimed that if customers were storing less than 500GB of compressed data in the Redshift data store, then the "lowest cost and highest performance option" is the new nodes.

This is likely because the Redshift tech (based in part on ParAccel's database software) is based around columnar data storage with advanced compression techniques and fast disk and network I/O. By adding in SSDs, companies can get a better I/O performance and reduce turnaround times on complex queries, though their storage will be more expensive at scale.

Amazon launched the Redshift service in November 2012 and claimed the service would be cheaper than those offered by incumbents.

Now, Amazon reckons Redshift "has become the fastest-growing service in the history of AWS [Amazon Web Services]."

The service is one part of a new emphasis by Amazon on targeting enterprise jobs, and moving away from the bare bones infrastructure-as-a-service tech that Amazon Web Services is best known for. Redshift sits alongside other high-level tools like the Elastic Beanstalk platform-as-a-service, and the Citrix-slaying Workspaces VDI tech.

Initially, the new Redshift nodes are available in six of Amazon's ten data center regions, including US East (Northern Virginia), US West (Oregon), EU (Ireland), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney). ®
