Posit: A private cloud has less lock-in than a public cloud because realistic, practical alternatives exist and migration is possible
- Moving between public cloud services is practically impossible.
- It may never be possible.
- Your business process is hostage to a third party and completely outside of your control from a timeline, cost and change view
- Consider, your business is under threat and cutting costs is imperative. Your cloud provider is forcing a migration to a updated service and you have fixed time period to complete the upgrade process. You must spend to maintain service. Control is lost
- Loss of control is a lock in
In private cloud, you have some greater degree of control over these issues. Its a tradeoff.
- Take for examples, the collapse of public clouds by VMware, Cisco, HPE, Verizon etc. All of these are forcing your business to undertake an activity outside of your control.
- Amazon is quite ruthless about forcing customers to fit its technology. Machines are force rebooted, products are deprecated and discontinued reguarly.
- Azure if forcing upgrades on its SQL products as a rapid pace, often beyond what customers are able to handle (they don’t have the resources to change their systems).
