How does ordinary virtualization relate to virtualization used in a cloud computing environment? That was the topic of a talk at the Cloud Computing Expo in Santa Clara last week. Is there a difference? Or is it merely a logical or organizational distinction but the techniques used are still the same? Adam Hawley talked about this, slides linked to in the article, and how Oracle's products do or will fit into this paradigm. Database services in the cloud, Application Server services in the cloud, middleware provisioning in the cloud for yourself and your customers, isolation, privacy, security, replication, disaster management. Everything is still the same yet different.
Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.
