Once you’re at any scale, you’re already de facto locked in. “Infrastructure has weight”. It’s a major undertaking to migrate infrastructure once you e spent time creating data, setting up a hybrid network infrastructure, training, going through compliance, DNS entries, configuration, load balancers, validation and regression testing, etc.
The typical large corporation depends on so much third party software and so many services, it’s a pain and costly to migrate from any of them.
You can’t imagine how much coupling companies can do to something as simple as WorkDay.
I wish all of the idealists who want to maintain “cloud independence” would do a thought experiment and set up a realistic project plan and budget to migrate their infrastructure to another platform even if they didn’t use any proprietary offerings.
And then take that plan to their CTO and see where he wouid place it on the list of priorities for their company and do a realistic cost/benefit and risk analysis.
