Rackspace vs AWS vs Internap

 

I wanted to make sure you saw the new research report from Cloud Spectator, Benchmarking a NoSQL Database on Bare Metal versus Public Cloud. Cloud Spectator’s benchmark tests confirm the price-performance advantages of running big data workloads in bare-metal environments over comparable virtual offerings from Amazon Web Services and Rackspace.

Example findings include:

  • Internap outperformed Rackspace by 5x and Amazon by 51% on throughput speed when loading data into the database.

  • Internap had 59% less latency than Amazon and 32% less latency than Rackspace when testing a balanced workload.

  • The equivalent monthly price of hosting an Aerospike database on Internap’s bare-metal servers was at least 78% less expensive than doing so on Amazon I2 or Rackspace Performance Server.

Like a blog it captures small items on many topics which are mostly read through my feed. Like a wiki, however, each entry is a wikiWord as I try to organize the bliki through named concepts. I write the entries to be things that are valid for a long time, and most bliki posts are just as valid now as when I wrote them.

The bliki, like much of the website, has grown and now has over 400 entries. The tags are probably the best way to explore it. There is also a page with all the recent bliki entries. All bliki entries are put, with full text, into my news feed.
