The premise of your counter argument ...Dear Chugh,<br /><br />The premise of your counter argument is that enterprise cloud does move you along the transition to a more commodity environment where architectural best practices shift from N+1, scale-up, disaster recovery to design for failure, scale-out and chaos engines.<br /><br />This is not the case as "Enterprise" cloud is designed to make migration of legacy environments as easy as possible by avoiding such architectural changes and duplicating the product world with high resilient & scaleable virtual machines.<br /><br />You even infer this with in the point regarding keeping the "lights on".swardleyhttp://www.blogger.com/profile/04702421918430488600noreply@blogger.comtag:blogger.com,1999:blog-24244078.post-60749035580889049562011-12-12T05:51:27.285Z2011-12-12T05:51:27.285ZI am a big proponent of commodity public cloud but...I am a big proponent of commodity public cloud but also see value of enterprise clouds. One line caught my attention:<br /><br />"Enterprise clouds don't move you along that architectural transition and here there's a real gotch'a" - and herein lies a gotch'a for the author as well IMHO :)<br /><br />This line exposes a hidden assumption that commodity clouds some how magically help you to move along the <br />"architectural transition" curve, at least more so than enterprise clouds do. Is that really true? I think not. <br /><br />The problem of architectural transition remains the same regardless of whether you use Commodity cloud or Enterprise cloud. So if that is true, what is the point against enterprise cloud?<br />Greenfield apps could leap frog the architectural transition and move to commodity clouds, sans doubt.<br /><br />Despite all rhetoric the fact remains that businesses need to keep their lights on for most critical applications such as ERP or enterprise data warehouse systems even when they move to the cloud. Enterprise clouds offer that by definition and commodity clouds do not. Such mission critical apps will not undergo architectural transition overnight and in fact will co-exist with modern apps for a very long time. Consequently enterprise cloud shall exist for a very long time.<br /><br />What is author's case against enterprise cloud? Still unclear, would love to understand more.Harshaan Singh Chughhttp://www.blogger.com/profile/00658251794113795157noreply@blogger.com
