   Lot of companies migrate off cloud, but really no companies   
   migrate off cloud.   
      
   It depends on exactly what we are talking about.   
      
   The traditional model from 20 years ago - a data center with:   
   * a mainframe   
   * some commercial Unixes on a RISC platform   
   * some relative unique Linux and Windows server on x86-64 or   
      ESXi on x86-64   
      
   New model with:   
   * Linux containers deployed to Kubernetes cluster   
   * standardized Linux VM's   
      
   Nobody is going back from the new model to the traditional model.   
      
   Everybody is staying with the new model.   
      
   But a significant number of companies are migrating either fully or   
   partially   
   from public cloud to private cloud.   
      
   Still the new model. But the companies own the hardware instead of   
   Amazon/Microsoft/Google/Oracle owning it. And the companies manage their   
   own platform software instead of using managed services.   
      
   The reasons are not technical but:   
   1) Cost - if the company have a relative stable workload and have necessarry   
       inhouse IT expertise, then it is often lower cost.   
   2) Regulatory issues (data can not leave state/country) or poltical reasons   
       (dependency on another country).   
      
   But the practical change is often small.   
      
   One of the most public migrations is that of 37signals. Not because they   
   are a huge company, but because DHH is a very public person. They moved off   
   AWS and to their own servers. Servers that they paid for, but servers that   
   are hosted in a colocation data center and servers that was installed by   
   a third party company. It is quite possible that no 37signals employee has   
   ever been in the same rooms as their servers. From a technical   
   perspective not   
   so big a difference between AWS data center and co location data center, but   
   they saved money from paying Dell once instead of Amazon monthly!
