Excellent simulation feature, realized scalability, with community support forums
Pros and Cons
  • "The most valuable feature is that it gives you the same environment as on a developer machine as well as a production machine relevant to specifications."
  • "I would like to see better management layers."

What is our primary use case?

Our primary use case is to build and bundle applications.

What is most valuable?

The most valuable feature is that it gives you the same environment as on a developer machine as well as a production machine relevant to specifications. The binaries and dependencies are all bundled together and they are in a similar fashion in both places.

What needs improvement?

I would like to see better management layers. One example of this would be binary shipping. I would also like to see Docker utilize a concept like Red Hat Family.

For how long have I used the solution?

I have been using Docker for three to four years.

What do I think about the stability of the solution?

The stability is excellent. Sometimes, memory management can be tricky.

What do I think about the scalability of the solution?

Docker is scalable on both community and commercial levels. I am using the community version. There are around one hundred to one hundred and twenty of us using Docker on a daily basis.

How are customer service and support?

For customer support, we are using the documentation on the forums and they are suitable.

How was the initial setup?

The initial setup was very simple and straightforward.

What about the implementation team?

You can use either an in-house or vendor team. We simply downloaded Docker into our organizational environment.

What other advice do I have?

There are a sufficient number of YouTube videos and best practices to build Docker. I would encourage a potential user to investigate those videos. On a scale of one to ten, I would rate Docker a nine.

Which deployment model are you using for this solution?

Public Cloud

Excellent scalability, easy to understand and follow, most widely accepted
Pros and Cons
  • "Docker is easy to understand and follow. It provides good scalability to the application."
  • "I would like to see a single package image orchestration bundled together."

What is our primary use case?

Our primary use case is to build images for all of our microservices and UI applications. We are building an enterprise-grade application where there are a lot of integrations. We have around forty to fifty different microservices which we are deploying using Docker and all of the orchestration through Kubernetes.

What is most valuable?

Docker is easy to understand and follow. It provides good scalability to the application.

What needs improvement?

I would like to see a single package image orchestration bundled together. Although Docker has ways to implement, it is not as flexible as Kubernetes.

For how long have I used the solution?

I have been using Docker for the past six months.

What do I think about the stability of the solution?

Docker is currently stable.

What do I think about the scalability of the solution?

There is definitely scalability with Docker. We have more than two thousand working on products.

What's my experience with pricing, setup cost, and licensing?

It is both open source for public projects and a licensed solution.
When you are talking in terms of a dedicated technical support team you may need to purchase a support license.

Which other solutions did I evaluate?

Docker is the most widely accepted image-building tool. It has a large support base and community. 

What other advice do I have?

I would recommend having good POC's because there are certain niche cases that you might not consider while just doing a POC. There are a lot of activities, that need to be considered, and how this application is going to be consumed by other applications. I would rate Docker a nine on a scale of one to ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Has great customization features and helps our organization with proofing designs
Pros and Cons
  • "It is neat and very flexible."
  • "Unfortunately, base images are not currently available."

What is our primary use case?

Docker is a POC setup and a proof of concept. Therefore, we work closely with other clients and proof some designs.

What is most valuable?

We have found the customization feature most valuable. Docker is used for customizing images and is a self-hosted or self-managed application. It is neat and very flexible, and you can have all your applications and dependencies in one image. You can use that image in different applications and run it off other applications. You only need a registry to put them in, and you can leverage it. Kubernetes helps with orchestration.

What needs improvement?

The product could be improved by providing more documentation and detailed tutorials for the initial setup. Additionally, in the next release, I would love them to add the latest base image for DPN. They can look closely into upgrading their base images to assist some of our clients in looking for specific base images to build their applications. Unfortunately, base images are not currently available.

For how long have I used the solution?

We have been using this solution for approximately two years.

How are customer service and support?

Our experience with technical support has been decent. It falls in line with the general support aspect of Docker. It depends on the plan we are using. So if you have a higher goal, you get full support. I rate our experience with customer service and support an eight out of ten.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have not worked with other similar solutions.

How was the initial setup?

The initial setup is straightforward. I rate it a six out of ten.

What's my experience with pricing, setup cost, and licensing?

I cannot comment on licensing costs as I don't have access to that information.

What other advice do I have?

I rate this solution nine out of ten. The solution is good and easy to use but can be improved by including more documentation and detailed tutorials for the initial setup.

Easy to use, and great for building containers and handling multiple apps
Pros and Cons
  • "We are able to stop our containers or stop the service with a single command."
  • "We have found that it is not easy to install it into a Windows system."

What is our primary use case?

We primarily use the solution to create the node for the containers to deploy multiple apps. We have iOS applications in the containers, and we can build multiple microservices in the containers. It provides access to the content for public IPs. We can host it, for example, on AWS can contain some instances in Azure or AWS.

How has it helped my organization?

In my project, it is easy to just build all the microservices locally in my local system through Docker. I can use it to test and deploy all the microservices in containers, including the front-end applications as well. Everything communicates from container to container. It's very easy. I can have multiple Docker files and deploy them easily into the cluster.

What is most valuable?

It's really helpful for building containers and handling multiple apps.

We have three applications. They are running on Windows using C Sharp, Java, and Python. We're able to build containers for each.

It's easy to run a single command and run the containers on a local machine. It's very easy to adjust the logs and describe your containers properly.

We are able to stop our containers or stop the service with a single command. That's very handy.

The stability is very good. 

There are a lot of features included in the solution. 

What needs improvement?

We have found that it is not easy to install it into a Windows system. I get very frustrated with Windows. When I install a Docker instance on a Windows machine, it is not easy to handle. In contrast, it's very easy to use on the Mac OS.

I'd like the solution to be more flexible.

For how long have I used the solution?

I've used the solution for about three to four years. 

What do I think about the stability of the solution?

The solution is reliable and stable. I'd rate the stability nine out of ten. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

The solution is very scalable. I'd rate the scalability nine out of ten.

How are customer service and support?

The solution is open-source the support you get depends on the licensing you have.

How would you rate customer service and support?

Neutral

What was our ROI?

I have witnessed an ROI while using the solution. I'd rate the ability to achieve ROI nine out of ten.

What other advice do I have?

I'm not sure which version of the solution we're using. It's likely the latest.

I'd recommend the solution to others. It is very easy to use. I'd rate it eight out of ten.
