What can open source companies learn from Mark Benioff? Plenty. READ MORE

Update: Sun has expanded its Cloud Computing portfolio with the recent acquisition of Qlayer, a cloud computing company that automates the deployment and management of both public and private clouds.  The Q-layer organization, based in Belgium, is now part of Sun's Cloud Computing business unit which develops and integrates cloud computing technologies, architectures and services.

Cloud computing is about managing petascale data. Sun's server and storage systems can radically improve the data-intensive computing emerging in the cloud. Some clouds are closed platforms that lock you in. Sun's open source philosophy and Java principles form the core of a strategy that provides interoperability for large-scale computing resources. Sun's virtualization solutions for advanced …

I had so much to say in response to a recent post asking about virtualization from Jennifer Glore that I realized it was long enough to be a blog post.

It really depends on what you’re looking to do. Many companies don’t have the money and staff to have an in-house data center with proper power and network redundancy; others don’t want the depreciation associated with owning computer hardware (even if they leased space in a data center, they’d have to buy equipment to put in it).

Some reasons to virtualize:
1) you need a fresh machine and cannot wait to order a new one or re-purpose an older one.
2) your need for machines/services fluctuates (and again, re-purposing takes time). This need can be as broad as employee desktops or as …

SmugMug , a photos and videos publishing site, goes into Production on Open Solaris + MySQL + ZFS. Check out this story on why a Linux geek decided to move his site from Linux To Open Solaris.

Don MacAskill, chief geek and CEO of SmugMug says"  ZFS is the most amazing filesystem I’ve ever come across. Integrated volume management. Copy-on-write. Transactional. End-to-end data integrity. On-the-fly corruption detection and repair. Robust checksums. No RAID-5 write hole. Snapshots. Clones (writable snapshots). Dynamic striping. Open source software. " He is also excited about the CoolStack 5.1 stack available in Open Solaris along with …

I recently attended an interesting talk by Brion Vibber, CTO of WikiMedia Foundation, a non-profit organisation that runs the infrastructure for Wikipedia. He described how his team of 7 engineers manages the Wikipedia site that gets on an average of 7 billion page views per month. The highlights from the talk are listed below that included the architecture of the site infrastructure to scale up to the traffic that is received. They are ranked amongst the Top 10 sites in terms of traffic.

The site runs on the LAMP stack and you know what that is:

• Linux
• Apache
• MySQL from Sun
• Perl/PHP/Python/Pwhatever :-)
  

WikiMedia runs the site on about 400 x86 servers. Of those, about 250 run the webservers and the remaining run MySQL database. Recently they acquired the …
