Measuring the Performance of Clouds – GoGrid

Tuesday, March 17th, 2009 by

Raditha Dissanayake posted a blog entry comparing Amazon EC2 and GoGrid performance. Unfortunately, we think Raditha did not use the most rigorous methodology possible for doing his comparison. It would be inappropriate for GoGrid to performance test Amazon’s EC2. In fact, their Customer Agreement may actually make such activity questionable, but IANAL (I Am Not A Lawyer).

Let’s take a more rigorous look at GoGrid disk subsystem performance.

Framing the Issue

As a start the entire issue is a LOT more complex than can potentially be covered here. Today’s disks, hard drive controllers, and operating systems have many different kinds of caching mechanisms. In addition, virtualization systems like Xen can impact results in unexpected ways. For example, did you know that Xen can be deployed in two major manners?

Either ‘paravirtualized’ or ‘hardware virtualized’. The two different models almost certainly impact any testing methodology. And yes, you guessed it, Amazon and GoGrid don’t configure Xen in the same way. Amazon uses paravirtualization and GoGrid uses hardware virtualization. Beyond this public information neither Amazon nor GoGrid provide significant details about their infrastructure considering it, rightfully so, proprietary intellectual property.

Without a deep understanding of all of the issues it’s difficult to do a test much less a proper comparison.

Podcast: GoGrid’s Telemachus Luu & Michael Sheehan and f5′s Peter Silva on Cloud Computing

Wednesday, March 11th, 2009 by

f5_devcentralLast week I had the pleasure of joining Peter Silva (Technical Marketing Manager at f5) and Telemachus Luu (Director of Business Strategy at GoGrid/ServePath) in a podcast hosted by f5 on their DevCentral community site. The topic of the podcast was “Cloud Computing” (of course) but specifically how using f5 technology, ServePath and GoGrid were able to create a full spectrum of hosting solutions ranging from Dedicated and Managed Hosting (ServePath) and Colocation hosting(ColoServe), up and into the Clouds with GoGrid.

The podcast titled “Hosting in the Cloud with ServePath and F5” covers a variety of topics including:

  • ServePath’s product extension from managed hosting to cloud hosting with GoGrid
  • The “Cloud Pyramid” and distinctions within the various Cloud layers
  • Understanding the nuances within the Cloud Infrastructure layer: “Infrastructure Web Services” & “Cloudcenters”
  • How f5 was paramount in creating a Cloud Computing Infrastructure offering

I encourage you to listen to this 30 minute podcast (forgive the audio quality, we were in an empty conference room) which is available at the following locations:

  • On f5′s DevCentral site
  • As a downloadable MP3 file
  • Play from this site (click on the graphic below)

GoGrid Whitepaper: “Scaling Your Internet Business”

Wednesday, March 11th, 2009 by

Today we released a new Whitepaper written by Randy Bias, GoGrid’s VP of Technology Strategy titled “Scaling Your Internet Business.” If you are a Web Application Developer or interested in learning about scalability, specific to how it relates to Web Applications in or outside of the Cloud, I encourage you to give this whitepaper a read.

The whitepaper can be downloaded here from the GoGrid site.

Scalability is critical to the success of many organizations currently involved in doing business on the Web or who are providing information that may suddenly become heavily demanded. While there are many strategies that IT organizations can undertake, the way they are designed and implemented can make or break these businesses.

The GoGrid whitepaper discusses the following topics:

  • How web applications scale
  • Cloud Computing and scalability therein
  • Thinking through and choosing a scaling strategy
  • GoGrid & ServePath scalability options

Scalability can come in all shapes, sizes and flavors. You can scale “up” (vertically) or “out” (horizontally). Choosing the right option can be tricky, if not daunting. Depending on what you want your strategy to be, you can choose “cloud-only”, “dedicated/colocated-only” or a “hybrid” approach.
