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."
  • "If you install Docker on a host, it creates its own firewalls. It can become an issue."

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?

Suitable for enterprises and helps with device management
Pros and Cons
  • "In our line of work, we've been involved in various sectors, such as industrial products, transportation, client engineering, telecom, and medical. For instance, we're currently developing an IT platform. One key use case we're tackling is device management."
  • "Docker needs to improve its pricing."

What is our primary use case?

In our line of work, we've been involved in various sectors, such as industrial products, transportation, client engineering, telecom, and medical. For instance, we're currently developing an IT platform. One key use case we're tackling is device management.

We're looking at managing devices within our setup. These devices send data or signals, which then get transferred to the cloud. It's all about handling the lifecycle of these devices, deploying them, and managing non-provisioned ones, both on our end and on the client's side.

What needs improvement?

Docker needs to improve its pricing. 

What do I think about the stability of the solution?

I rate Docker's stability a nine out of ten. 

What do I think about the scalability of the solution?

One of the primary reasons we use the tool is its scalability. It scales easily, and we haven't had any issues with it.

How are customer service and support?

Docker's support is user-friendly, fast, and knowledgeable. 

How was the initial setup?

The tool's deployment difficulty is medium.

What other advice do I have?

It tends to make sense as an investment for larger enterprises, but the cost might seem expensive for smaller businesses.

Provides good load-balancing features and helps save costs
Pros and Cons
  • "The solution helps save costs."
  • "Docker management is very difficult when we have a large number of nodes."

What is our primary use case?

We use the tool for some of our services. We use it for containerization.

What is most valuable?

Load balancing features are valuable. We are leveraging this software for containerized services. We are using EKS for orchestration. We are leveraging almost all features. The solution helps save costs. We can know how much CPU memory is required so we can manage it accordingly.

What needs improvement?

Docker management is very difficult when we have a large number of nodes.

For how long have I used the solution?

I have been using the solution for the last two years.

What do I think about the stability of the solution?

I rate the tool’s stability a six or seven out of ten.

What do I think about the scalability of the solution?

I rate the tool’s scalability a six out of ten. We have more than 500 users. The tool is used extensively. We have plans to increase usage in the future.

How are customer service and support?

We get good support from AWS.

How was the initial setup?

The setup is straightforward. We need ten people for deployment, including managers, developers, and the IT team.

What about the implementation team?

We can deploy the product ourselves.

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

We use the open-source version.

What other advice do I have?

We use EKS for large applications. I will recommend the solution to others. If people want to leverage load balancing and containerized services with less CPU and load management, they can use Docker. We must pay for EKS based on the clusters and nodes we use. The price depends on the use case. Overall, I rate the solution an eight out of ten.

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?

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.

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.

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.

Pros and Cons
  • "Docker allows you to run multiple virtual machines independently."
  • "The solution is not easy to manage and it is one of the reasons why people introduce orchestration tools to manage it."

What is most valuable?

Docker allows you to run multiple virtual machines independently. 

What needs improvement?

The solution is not easy to manage and it is one of the reasons why people introduce orchestration tools to manage it. 

For how long have I used the solution?

I have been using the solution for six to seven years. 

What do I think about the stability of the solution?

The tool's stability is high and I would rate it a ten out of ten. 

What do I think about the scalability of the solution?

We use the solution 24/7. 

How are customer service and support?

The tool is an open-source product and there is no technical support for it. 

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

We use Hyper-V and VMware as per our client's requirements. 

How was the initial setup?

The tool's setup is difficult and I would rate it a two out of ten. The tool's POC can be completed in a couple of hours. However, if the project is big, then deployment can take around one to two months to complete. 

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

The solution is an open-source technology and not a commercial product. However, you will have to pay sometimes. The tool's pricing depends on the vendor. 

What other advice do I have?

I would rate the product a nine out of ten. The solution is a virtualization technology that is more like a mini-computer.

Helps to replicate anything in the local machine using a simple command
Pros and Cons
  • "I think the best feature is to replicate anything in our local machine using a simple command."
  • "The product does not have an extensive documentation. The tool does not have good scenarios. We have to go through the GitHub repository and investigate similar scenarios. Also, if you are copying multiple things, then you can jeopardize the copy number. The copying aspect also lacks a UI part. We also need to limit the memory."

What is most valuable?

I think the best feature is to replicate anything in our local machine using a simple command. 

What needs improvement?

The product does not have an extensive documentation. The tool does not have good scenarios. We have to go through the GitHub repository and investigate similar scenarios. Also, if you are copying multiple things, then you can jeopardize the copy number. The copying aspect also lacks a UI part. We also need to limit the memory. 

For how long have I used the solution?

I have been using the tool for four years. 

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 tool is very easy to scale up. My company has 100 percent usage for the product. 

How are customer service and support?

I have never contacted the support. I always look at GitHub instead of raising a ticket. 

How was the initial setup?

The product's setup is easy and straightforward. However, you will encounter difficulty in customization. The speed of the product's setup depends on the bandwidth and download speed. 

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

The product is a free open-source tool. 

What other advice do I have?

I would rate the product a nine out of ten. 

Which deployment model are you using for this solution?

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.

Provides containers independent of the operating system and is easy to use
Pros and Cons
  • "The solution's most valuable feature is having containers independent of the operating system or environment."
  • "The solution’s documentation could improve a bit."

What is our primary use case?

I have an energy management platform running on AWS, but I saw some limitations in that setup. So I'm designing one to be independent and containerized rather than using AWS services. That is why I'm now checking if I could go to a Red Hat OpenShift or EKS.

What is most valuable?

The solution's most valuable feature is having containers independent of the operating system or environment. Also, you can just be modular and scale with the solution.

What needs improvement?

The solution’s documentation could improve a bit.

A new feature was added to Kubernetes to deploy and manage containers. Currently, it is a bit of a tedious process to combine containers using Docker. Hence, a new way to deploy containers would be a good feature to be included in Docker's next release.

For how long have I used the solution?

I have been using Docker for one year.

What do I think about the stability of the solution?

It is a stable solution.

What do I think about the scalability of the solution?

The solution is scalable.

How are customer service and support?

I've never contacted Docker's technical support, but I contacted the developer of a few images that were incompatible with Mac.

How was the initial setup?

The initial setup is fairly easy and fast.

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

The pricing of the solution is fairly cheap.

What other advice do I have?

I am using the latest version of Docker. Currently, we have four people using Docker in our company. My company chose Docker because it is popular and used on all platforms.

People should definitely use Docker. Since there's a learning curve, users should first start small and then expand. It also depends on your use case. You need to understand what Docker is because it is not always the right solution for everything. Docker is very lightweight, and you can use it to build containers and create your application. It will be modular and cross-platform.

Overall, I rate Docker an eight out of ten because it is a cross-platform solution that is straightforward and easy to use.

Affordable, user-friendly, and easy to deploy
Pros and Cons
  • "The deployment is quite fast, which is beneficial."
  • "There is always room for improvement. I often refer to forums such as StackOverflow to learn from other developers' experiences and the challenges they have faced while using Docker."

What is our primary use case?

I am able to containerize my application using Docker on my Docker account.

Deploying two solutions is much faster and easier for me on Docker. Docker makes deployment much simpler and more efficient.

What is most valuable?

The deployment is quite fast, which is beneficial.

I think Docker has done an excellent job on their website in illustrating the installation process and addressing any challenges that may arise. 

Their website provides clear instructions for deploying Docker on various operating systems, including Mac, Linux, and Windows environments.

What needs improvement?

There is always room for improvement.

I often refer to forums such as StackOverflow to learn from other developers' experiences and the challenges they have faced while using Docker.

For how long have I used the solution?

I have been using Docker for the last two years.

We are using the most recent version. I released the most recent update two or three days ago.

What do I think about the stability of the solution?

I prefer not to disclose that specific project at the moment because it is a personal one and not related to LiveScale.

I would rate the stability a nine out of ten.

What do I think about the scalability of the solution?

I am the only user.

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

I have used Apache Web Server.

How was the initial setup?

The initial setup is straightforward.

It can be deployed in less than thirty minutes.

What about the implementation team?

I was able to deploy it myself.

Regarding my last deployment, I used Docker as a containerization platform to package and deploy my application. As for the design, I purchased the Blue on the Bureau theme for $250 and used it on my Mac computer.

I found the deployment process to be quite straightforward.

It is installed on-premises on my local machine. However, whenever I need to make updates or changes, I push them to Git to maintain a version control account.

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

I prefer to pay on a monthly basis.

The pricing is reasonable. 

Pricing is based on the number of users.

What other advice do I have?

Based on my experience with Docker and the speed and ease of deployment it offers for various applications, I would highly recommend it to others.

I would rate Docker, a nine out of ten.
