Time-saving deployment with seamless virtualization for diverse environments
I used Docker to Dockerize Java code. We had a code base, and I needed to create a Docker image from it so that it could be deployed. At the time, we used Docker Compose, which is somewhat similar to Kubernetes Docker allows virtualization at a higher level without the need for a host machine.…

The biggest advantage is how simple the technology was.
I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is Docker has a fast learning curve."
"Traditional deployments take more time and builds can be inconsistent across different environments. Docker solves these issues."
"We find the auto scaling and auto healing functionality of this solution very good."
"The most valuable feature of Docker is its integration with other solutions, such as KVM and AlmaLinux."
"The capability of the solution to convert an application into a Docker image is a vital functionality"
"This makes our publisher fast and our containers are isolated from each other."
"The tool's most valuable feature is its sandbox environment. It makes it very easy to run and test applications without needing configurations, which is the core advantage of containerization. Kubernetes and Helm are helpful as they provide high-level metrics, making tracking the status of all the containers and applications running easier."
"I think the best feature is to replicate anything in our local machine using a simple command."
"The biggest advantage of OpenLegacy was how simple the technology was. We were able to build out the OpenLegacy parts very quickly. We put together a couple hundred APIs in six months."
"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."
"Opens the door to connect modern web products to an old legacy system."
"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."
"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."
"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."
"Without OpenLegacy, it would take us several months to create the same services."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
 

Cons

"The command line interface could be more intuitive. I constantly struggle with it."
"We have found that it is not easy to install it into a Windows system."
"I would like to see a single package image orchestration bundled together."
"The solution is not easy to manage and it is one of the reasons why people introduce orchestration tools to manage it."
"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."
"The stability could be improved."
"Docker could improve by providing the ability to use the GPU for parallel processing. If there was the capability of using the GPU it would improve the machine learning that I want to use."
"The Kubernetes blocks need improvement since Docker has many holes in it."
"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."
"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."
"They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be."
"Debugging and logging for programmers could be better."
 

Pricing and Cost Advice

"The pricing of the solution is fairly cheap."
"Docker is a free-to-use solution. However, Docker Enterprise is not free."
"It's an open-source solution, so it doesn't cost anything"
"Docker has made some changes and there is an enterprise version that is affordable."
"Regarding pricing, we primarily use AWS for our deployments since we have funding for it. We don't spend much on Docker-specific services, just the containerization product. Docker Hub isn't particularly expensive either, so overall, the pricing is pretty reasonable."
"Docker is cost-effective and open-source."
"We use the open-source version."
"The product is a free open-source tool."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."

Questions from the Community

What is your experience regarding pricing and costs for Docker?
The setup cost has balanced out, and I find Docker's pricing reasonable. Docker Engine is free and open source for Linux, and Docker Desktop is free for individual developers and small teams, but a...
What needs improvement with Docker?
As Docker is already a very mature tool, there are areas where it can be improved based on real-world usage. One area I consider is the Windows container experience. The pain point here is that Win...
What is your primary use case for Docker?
My main use case for Docker is to package applications into consistent, portable containers and use those images across CI/CD and production environments. I containerize applications so they can ru...
