I learnt a lot from it (still a noob though). But I agree that I see most vendors asking for crazy requirements when offering products to run in VM&#8230;. and that looks like that kills that idea itself of having a virtualization environment because that VM looks like requires a dedicated server&#8230;. So right-sizing your product\/VM is very important. I agree with the statement that vendors dont really do load testing for their VM offering and the high requirements it is an excuse to &#8220;avoid&#8221; problems from customers.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is a very interesting article about how Longest Prefix Matching is done in networks chips.
