7. The Big Challenge...
In the last two years we often talked with our customers who were interested in
using docker. The main questions we always heard, were similar:
Common Customer questions:
– How is a new Docker setup done right?
– Do we need extra software like Consul, Vault, etcd…?
– Is it possible to dockerize our existing application stacks?
– We want microservices, but we need some time to change our application
development.
– Is it possible to setup a simple Docker Environment in our existing platform?
Do you have a solution for us?
