by Lydia Leong  |  April 29, 2009  |  Comments Off

I’m at Gartner’s business continuity management summit (BCM2) this week, and my second talk, upcoming later this morning, is on the relevance of colocation and cloud computing (i.e., do-it-yourself external solutions) to disaster recovery. My recent written research has been all focused on cloud, although plenty of my day to day client time has been [...]

McKinsey on cloud computing

by Lydia Leong  |  April 16, 2009  |  3 Comments

Google App Engine and other tidbits

by Lydia Leong  |  April 8, 2009  |  1 Comment

As anticipated, Java support on Google App Engine has been announced. To date, GAE has supported only the Python programming language. In keeping with the “phenomenal cosmic power, itty bitty living space” sandboxing that’s become common to cloud execution environments, GAE/Java has all the restrictions of GAE/Python. However, the already containerized nature of Java applications [...]

Scala, Ruby, cost, and development trends

by Lydia Leong  |  April 6, 2009  |  2 Comments

A recent interview of some Twitter developers, on Twitter’s use of Scala has touched off a fair amount of controversy in the Ruby community, and prompting Todd Hoff of the High Scalability to muse on an interesting statement: At some point, the cost of servers outweighs the cost of programmers. We all know that the [...]
