Docker and containerization survey

You can also see the results of another survey, this time from the guys of DataDog, where they use the data they collect for showing some interesting facts:

• Real Docker adoption is up 5x in one year
• Docker now runs on 6% of the hosts they monitor
• Larger companies are the early adopters
• 2/3 of companies that try Docker adopt it
• Users triple the number of containers they use within 5 months
• The most widely used images are registry, NGINX, and Redis
• Docker hosts often run four containers at a time
• VMs live 4x longer than containers
