What is SaffronSierra (in plain english)?
Wednesday, February 17th, 2010 by admin
I recently received a request to describe SaffronSierra “in plain english”, this post will attempt to do just that.
SaffronSierra is a cloud-based, hosted version of SaffronMemoryBase. SaffronSierra enables developers to easily leverage the analytical powers of SaffronMemoryBase using a simple REST API. Using SaffronSierra, you don’t have to worry about downloading, installing and configuring software. You simply login to your SaffronSierra console and press “Start”. Within minutes, you will have a private instance of SaffronSierra ready for your use. Once your service is available you can start putting your data into SaffronSierra and powering your applications with advanced analytics. We hope that SaffronSierra enables people to quickly realize the benefits of SaffronMemoryBase in a low-cost, low-risk way.

TweetDive Worlds
Tuesday, February 16th, 2010 by admin
Up until today if you were to login into TweetDive you would have only seen data from what we call the “Money” world. TweetDive could only display Twitter data that had been ingested into this one SaffronSierra instance. Today we refreshed TweetDive and now users have access to more “worlds”. A “world” represents a Twitter account paired with a SaffronSierra instance. Now when you login you should see the world selector towards the top-right of the screen.

Amazon CloudWatch Interface for Common Lisp
Thursday, February 4th, 2010 by David Young
To complement our Common Lisp EC2 interface, I’ve written a similar package for Amazon’s CloudWatch, an “easy-to-use web service that provides comprehensive monitoring for Amazon Elastic Compute Cloud (Amazon EC2) and Elastic Load Balancing”. There are currently just two operations provided by CloudWatch: ListMetrics and GetMetricStatistics, both of which are supported by our new package.
The CloudWatch Lisp interface has some work remaining; mostly just parsing the responses from Amazon into more useful representations of the metrics (similar to the way we transform EC2 responses). Since GetMetricStatistics can return a lot of information, I’ll have to decide how best to represent this data in an easy-to-use, Lispy fashion. At present, the CloudWatch responses are filtered through the s-xml package and returned in a “parsed-xml” format.

SaffronSierra Transition
Tuesday, February 2nd, 2010 by admin
We’re going to be moving SaffronSierra over to a new look and feel over the next few days. We’ll start will the blog portion of the site and then we’ll move to the console. The two pieces of the site may be out of phase for a bit while we flip the switches.
Also, as part of this transition we’ll be moving SaffronSierra customers off of Amazon Payments and onto normal credit card billing. We’ll be contacting all of our customers individually about this transition.
We thank you ahead of time for your patience during this transition.

Sierra and Amazon EC2 Security
Tuesday, February 2nd, 2010 by David Young
A few weeks back there was an interesting article describing a security breach on Amazon’s EC2 Cloud. Of particular interest is this quote:
“On another part of the Sensepost presentation, they looked specifically at vulnerabilities of Amazon’s Web Services. To start off, they detailed the process involved in setting up a new instance on EC2… While Amazon has provided 47 machine images they built themselves, the remaining 2721 images were build by other EC2 users. Can you really believe that all of these images were built securely? Basically, the template directory is just a big archive of user-generated content.”
