When we are developing an application, we try various libraries. It is better to isolate one application from the other because if they install one library and then it doesn't work on the other end or while using a driver, then it doesn't work on the other driver. There is always this conflict that is bothering us, and that is where Docker separates containers to build applications.

A scalable solution that is useful for developing and testing applications
Pros and Cons
- "Docker is perfect for what I do...The solution is scalable."
- "Owing to a few shortcomings in its stability, I would say that its stability can be improved."
What is our primary use case?
What is most valuable?
Docker is a useful tool that we just implement and use directly.
What needs improvement?
It is a perfect solution for me stability-wise. Owing to a few shortcomings in its stability, I would say that its stability can be improved. It is important to note that I am not an expert to speak about what needs improvement.
In the future releases of Docker, we should be able to isolate a couple of applications. It should also be possible to isolate an environment.
For how long have I used the solution?
I have been using Docker for one or two years.

849,190 professionals have used our research since 2012.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is scalable.
We have a couple of users in our organization using Docker since it's just a test system right now.
We don't have plans to increase usage.
How are customer service and support?
We haven't contacted the technical support of Docker. We did search for the details of Docker's support team on Google.
Which solution did I use previously and why did I switch?
We have used the virtual machine named VMware previously. We switched to Docker because VMware was very clumsy when we tried to build a lot of virtual machines using it. VMware is best suitable as a business solution.
How was the initial setup?
The initial setup of the complete environment is complex, but Docker is easy to set up.
If you want to set up a complete environment, it will take a week, depending on the applications.
We don't do the deployment since we only look into the PoC phase. The company we work with does the deployment, and then they worry about the environment, infrastructure, and other things.
What about the implementation team?
We do the deployment by ourselves because we need to test or develop some applications and do the PoC phase.
What other advice do I have?
Docker is perfect for what I do, though it is really limited as a tool.
Overall. I rate the solution a ten out of ten.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

Data Analyst and Developer at Bridge Labs
A scalable solution that can be used for containerization and working with CI/CD pipelines
Pros and Cons
- "Docker's containerization property is its main selling point."
- "I want to see if new architectures have been incorporated in Docker or if we have to wait for another release."
What is our primary use case?
I use Docker for containerization, deployment, and to create packages. Docker has a wide range of uses and integrates well with other command-line tools like Terraform. Docker is most helpful when trying to work with CI/CD pipelines.
What is most valuable?
Docker's containerization property is its main selling point.
What needs improvement?
I'd like to see the new update on containers and what you can achieve with the new version of Docker by using containers. I would also like to know the range of applications for which it can be used. I want to see if new architectures have been incorporated in Docker or if we have to wait for another release.

I have been using Docker for one year.
What do I think about the stability of the solution?
I rate Docker a nine out of ten for stability.
What do I think about the scalability of the solution?
Docker is a very scalable solution. I rate Docker a nine out of ten for scalability.
How was the initial setup?
Docker's initial setup is straightforward. As a command line tool, it also provides you with docks to reference if you get stuck or have issues.
What about the implementation team?
The solution's deployment time depends on your internet latency or internet speed and the size of the container. If you are deploying a very large application, it will take some time to set up.
What other advice do I have?
Docker is deployed on-cloud in our organization.
To effectively use Docker, users should learn the basics of Docker and understand what containers and images are in Docker.
Overall, I rate Docker a nine out of ten.

- "Stability is an area with a shortcoming."
What is our primary use case?
I use the tool for SQL, MySQL, and web development.
What is most valuable?
I think that with Docker, it is easy to deploy it on different platforms.
What needs improvement?
Stability is an area with a shortcoming. Hence, stability needs to be improved.
For how long have I used the solution?
I have been using Docker for a year. Also, I don't remember the version of the solution I am using since it comes from the repository of Linux.
What do I think about the stability of the solution?
I rate the stability of the solution a nine out of ten.

Développeur applications at Trust Merchant Bank
Easy to manage, scale and creates lightweight applications
Pros and Cons
- "Docker creates lightweight applications that are easy to manage and scale."
- "Management can be improved with the necessary tools for orchestration."
What is our primary use case?
We are currently migrating some of our applications to Docker containers on the tenant to improve their performance.
We have already started migrating one application to Docker and Kubernetes. We plan to complete this migration within the next two days. Additionally, we plan to migrate our core banking software to microservices, which will be containerized using Docker and Kubernetes.
What is most valuable?
Docker is useful for container virtualization and installation of applications. Docker is a containerization tool that enables the installation of applications without the need for virtualization. Its primary advantage is that it allows for more efficient utilization of resources, such as with Oracle virtualization.
The key difference between Docker and classic consolidation is that the former does not rely on a physical machine for resource allocation. Instead, Docker creates lightweight applications that are easy to manage and scale, making the process faster and more efficient.
Moreover, Docker's scalability and manageability are the most valuable features for me.
What needs improvement?
There is room for improvement in terms of management. Because to use Docker, we should also use Docker as an orchestrator. But if Docker had the necessary tools for management, it would be very good.
For how long have I used the solution?
I have been using Docker for one year. Moreover, I am using the latest version.
What do I think about the stability of the solution?
It's stable because we just use it in a UAC environment.
What do I think about the scalability of the solution?
It is a very scalable solution. It is one reason we plan to migrate to Docker. It is very scalable. We still have technical people working on it. Most of the admins can work on those solutions.
How was the initial setup?
The initial setup of Docker is very simple and easy. If you know what you are doing, deploying the solution takes less than an hour.
What about the implementation team?
The deployment process depends on how the solution was developed. For Docker, you need to install it and then use Docker to get the necessary image for your OS. It keeps access and depends on your OS.
Once Docker is installed, you can get the necessary image for your solution. The deployment can be done in-house.
What's my experience with pricing, setup cost, and licensing?
The licensing cost is not expensive.
What other advice do I have?
Overall, I would rate the solution an eight out of ten. I would recommend using Docker if you are looking for a scalable solution.

Unix/Linux Systems Administrator at a financial services firm with 10,001+ employees
Detailed documentation, simple to use, but vertical scaling could improve
Pros and Cons
- "The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes."
- "If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created."
What is our primary use case?
Docker is an open-source container runtime for running container images. We are using Docker Swarm which is similar to Kubernetes but from Docker.
What is most valuable?
The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes.
There is a feature called overlay network for orchestrating containers in Docker Swarm which makes everything easy. You don't need a load balancer, which makes everything easy for accessing in one container. Additionally, it has internal DNS, which is not in Kubernetes.
What needs improvement?
If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created.
For how long have I used the solution?
I have been using Docker for approximately six years.
What do I think about the stability of the solution?
The performance of Docker is good. We usually follow best practices before deploying Docker, we have not had any issues since deployment.
What do I think about the scalability of the solution?
Docker is scalable. However, If you want to vertically scale, you have to do it manually. It doesn't have autoscaling.
We have seven people using Docker in my organization.
How are customer service and support?
The support from Docker is very good. The documentation is rich, any issue you face, somebody already faced and the information is available.
How was the initial setup?
The main reason we are using the Docker Swarm instead of using Kubernetes is you can set up Docker Swarm within five minutes. Docker is easy to set up. Once you install it, you can run it. In this case, the container runtime becomes Docker. The reason why we are using it is the vendor recommended Docker for bank sector purposes.
Setting up the master nodes in Docker is very easy.
What's my experience with pricing, setup cost, and licensing?
Docker is a free open-source solution. However, there is the Docker Enterprise which is a paid solution.
What other advice do I have?
The founder of Docker decided to move to Docker Enterprise to make revenue. There are many people moving away from Docker.
My advice to others is if you are using legacy applications they do not run well with containers. The person wanting to use Docker has to ask themself questions about themselves to determine if this solution is best. For example, the application that they want to run has to be scalable. People think Docker or Kubernetes is going to solve their problems, but no. If you have problems, it's going to amplify them, but if you have easy, smooth applications, it's going to make your life easier. The application itself has to be scalable.
The application has to be container ready, such as login inputs, does it follow the 12-Factor principles of deployment, and has security. Even if you don't have security, Docker can help with security if you don't have application security.
You need to consider how you are going to patch the images or the applications and if it will work with languages on WiFi, such as Java, Python, or Ruby version. Those are requirements you need to meet before deploying Docker. You have to find answers to many questions.
I rate Docker a seven out of ten.
I gave my rating a seven out of ten because autoscaling is necessary for cloud-native applications and it is not available. However, it's easy to use, scalable, and straightforward. It was the defacto container runtime for a long time until they went to an enterprise. Docker is very good in CI/CD. Anybody building images is using Docker to build the images and it works well with CI/CD.
Which deployment model are you using for this solution?
On-premises
