Guy Tel-Zur announces the end of grid computing, based on Google trends data for "grid computing" vs. "virtualization."
The data are fun, but I'm not convinced. Certainly the Google Trends data captures the fact that "virtualization" has replaced "grid computing" as the most popular industry buzzword. But given that industry has used "grid computing" mostly to mean "cluster computing" (e.g., Oracle 10-G, SGE), that doesn't say too much about grid per se.
Measuring adoption and impact is nevertheless an important goal. Thus we have integrated usage reporting mechanisms into our Globus software. We see continued growth in use, as captured by metrics such as service deployments. We're now trying to understand the underlying usage modalities. We believe that many are concerned with "eResearch" functions other than "federating computers"--e.g., on-demand access to computing [on HPC systems and/or EC2], data distribution, service publication and composition, etc. Do these functions count as "grid"? They do according to our article "The Anatomy of the Grid"--and if you look at the goals of projects such as D-Grid.
It would be interesting to see Google Trends data for just "grid." However, that word alone has too many different uses.
