What do you dislike?

My only issue with docker is that persistent data storage is very complicated since when a container shuts down all that information is gone unless you figure out with docker data volumes which are not easy to work with.

Containers are the place where companies should move and Docker makes it easy, Docker works on any device that needs it, to allow all employees to use the machine that best promotes their creativity and productivity according to their preferences. I love how easy it is to set up a virtual machine, add one and also get rid of it. The principle of pulling virtual machines away if they are no longer needed and building them when necessary is a delight, you can also create your own images based on those of one or more available in the hub. You can also create your private center to store private images of your software.

Recommendations to others considering the product

We recommend docker as a service to grow your business.

What do you dislike?

Slow if you try to run Docker inside a VM. Probably an unusual use-case, but some dev actually do development in VM.

What do you like best?

It allowed me to create a server without spawning a full VM (which, for development purpose is very heavy) - what's not to like about that?

Recommendations to others considering the product

The only time you need to re-consider using this is if your dev is developing inside VM with different kernels (example: Windows VM inside Linux host), it's very slow during startup. By slow, I mean like 10-15 mins startup time which is horribly slow.

What do you dislike?

Running any virtual technologies can sometimes be a resource hog. Higher end more expensive hardware is preferred to run virtualized containers than running the software natively.

What do you like best?

Quick and easy deployment of required developer software.

What do you dislike?

Trying to handle and get multiple docker containers to talk to each other is definitely a challenge and requires a bit of a learning curve. Docker environments are not perfect replicas of actual linux servers, since they provide their own type of architecture, but luckily it's close enough to where it can be useful.

What do you like best?

Docker allows for a customizable container for any type of application/microservice service/etc. I have used other virtualization tools before, such as VMWare, Vagrant, and none of them have been as easy to set up or easy to use.
