Bear in mind that the "cloud" has three layers: IaaS, PaaS, and SaaS.
SaaS (software as a service) involves complete IT solutions (i.e.
Salesforce, Google Calendar, NetSuite, etc), so it means the elimination
of most IT roles.
PaaS (platform as a service) basically means tools like databases, with
AWS RDS as a classic example. With PaaS migration, the cloud company is
supporting a limited set of database choices, and companies are
developing solutions with those tools.
IaaS (infrastructure as a service) basically means "servers" and
So while "most companies" are indeed migrating to the "cloud", sometimes
they are migrating to IaaS (a.k.a. someone else's servers), sometimes they are migrating to PaaS (a.k.a. someone else's tools), and sometimes they are migrating to SaaS (i.e. someone else's IT department).
The driving factor isn't necessarily lower cost, but more agility. As such, production systems are certain to migrate last, but non-production environments are certain to migrate first into what is called "hybrid data center".
Understand which choice your company is making, and plan accordingly.
If someone says "my company isn't migrating to the cloud", then someone is swimming in de Nile.
