- Docker gives us more flexibilty- Smaller and lighter Services

(Microservices)- Agility- Immutable Services- Faster deployment of apps and DBs- Scalability

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?
