So two things:<p>1. Cloud providers are making it easy for legacy businesses to take baby steps. You don&#x27;t have to use a NoSQL solution with AWS Dynamo, you can use Postgres with RDS. Or if you&#x27;re hyper-conservative&#x2F;stuck with legacy stuff, you can run Oracle with RDS. Or get an EC2 instance and install your own personal copy of Oracle on it. You don&#x27;t have to jump to full modernity right away, you can take the easy wins of hosted infrastructure first, and only later move up to the bigger wins of hosted platforms.<p>2. Yes, legacy stuff takes forever to disappear. There are still businesses running VMS inside of VAX emulators with COBOL apps on them. But once you&#x27;re in that &quot;super-conservative businesses won&#x27;t move away from you anytime soon&quot; area, you&#x27;re in a declining market. New businesses unencumbered by legacy won&#x27;t go down that road -- small businesses starting today will never buy an on-site server to start with (thanks to Office 365&#x2F;Google Apps&#x2F;etc.), and as they grow there&#x27;s no reason for them to change that policy anymore. EMC might never get a new customer, and even if they keep their old ones for some time, it&#x27;s just a question of how fast their decline is.
