Now all these commands are available in AWS panel, with a nice graphic user interface. So most of the users would not need this, unless they like a command line, like me.<br /><br />Regards,<br />Pradeeban.Pradeeban Kathiravelu, Ph.D.https://www.blogger.com/profile/02966629782470028375noreply@blogger.comtag:blogger.com,1999:blog-1478030848346376035.post-9192162905932469142013-04-26T03:57:16.771+01:002013-04-26T03:57:16.771+01:00Hi Kathiravelu, you've got a good guide here.....Hi Kathiravelu, you've got a good guide here... it looks like you posted this in 2011 :) but it is still relevant today.<br />There are online tools that you can use as well to manage some of these things if you don't want to use the command line tools. EZAutoScaling and ylastic are some. I work at EZAutoScaling, so I can set you up with a "free-forever" account if you want to use it. It's not Open Source :) and I don't know if you need an auto scaling tool today, but I thought you might find it useful.<br />boyanhttps://www.blogger.com/profile/04170152877824201743noreply@blogger.comtag:blogger.com,1999:blog-1478030848346376035.post-89818322273152279752013-04-25T10:55:51.391+01:002013-04-25T10:55:51.391+01:00hi Kathiravelu,
