Offers application conversion to Docker image and a mature environment
The learning curve with Docker is huge and extensive. Adopting Docker is a bit difficult because it requires a lot of expertise and background, including an understanding of networking and security concepts. Many professionals are facing issues with the different architectures that interact with each other in Docker. Whenever in our company, we are working with the production environment, professionals are hesitant to adopt Docker due to the extensive learning curve, and most of the team members in our company are more accustomed to an environment like VMware instead of Docker. Docker runs on scripts, so if AI can automate most of the scripting process in Docker, it would be a great advantage in the future version of Docker. As of now, we can create scripts utilizing most of the functions within Docker, but that initial planning phase wherein to understand exactly how you will plan for the resources, how you will convert applications into a Docker-based image, and similar tasks needs to be simplified so that more professionals can adopt Docker.

Manage infrastructure automation and smooth application deployment with robust auto-scaling capabilities
Kubernetes is highly valuable for its node-based setup, which allows for the running of multiple pods. This feature is essential for infrastructure automation and application deployment. Kubernetes also offers rollback control and auto-scaling capabilities, which are crucial for maintaining an application's availability even if nodes or pods go down. Additionally, Kubernetes supports load balancing to distribute traffic efficiently across multiple pods.

Quotes from Members

Pros

"Docker allows you to create small applications and containerize them. You can create multiple such application containers that can run simultaneously on the Linux operating system. In a DevOps environment where multiple teams are creating applications, developing new versions, and deploying applications frequently, Docker is very helpful. The greatest benefit of the solution is that you can create applications and multiple versions of the same application, distributing them across various Linux platforms. Setting up Docker is very quick; whereas setting up a Linux operating system can take five to ten minutes, you can set up a Docker-based Linux OS container within minutes. For developers who frequently create and deploy applications, Docker makes it easy to quickly develop, deploy, and run the latest versions. The solution’s stability is great. I rate it a nine out of ten. Regarding scalability, Docker doesn't require any separate configuration for multiple users. If you are trying to create an application quickly for testing or development purposes, Docker is the best tool available."
"The tool helps us in code versioning. I think it's pretty much easy to use and very straightforward. Even if someone is new to the tool, they can easily start using it with a little guidance or theoretical knowledge. Go through the tool and start using it without much struggle."
"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."
"It is neat and very flexible."
"I have seen end-to-end performance with Docker. It's a great tool, and it's the most popular container service in the market."
"The solution is easy to install."
"We are able to stop our containers or stop the service with a single command."
"Docker's containerization property is its main selling point."
"Kubernetes also offers rollback control and auto-scaling capabilities, which are crucial for maintaining an application's availability even if nodes or pods go down."
"It is a very good solution for deploying microservices in an application. It has a lot of freedom in it, which makes it very interesting. It is also web-enabled. You can run services in other virtual applications and virtual machines."
"The easy management of containers is one of the main features I have found useful."
"Kubernetes has everything. Its design structure is quite advanced, and its offerings are extensive. The practical feature was the seamless failover."
"Provides auto rollback and scale-up and scale-down functionalities."
"The best feature is autoscaling. It's effortless to use for scaling deployment parts, CI/CD, etc."
"The cluster is very stable with outward scalability and good performance."
"The most valuable feature is the support for Docker containers."
 

Cons

"As for improving Docker, I would like to see enhancements in its user interface and documentation to make it even more user-friendly and accessible. I believe Docker will expand its scope and reduce limitations to support more applications, both online and offline. For instance, in scenarios like deployments on ships or during upgrades, Docker can continue to offer software services and container-based intelligence."
"I would like to see better management layers."
"The runtime and security could improve in Docker. Security is paramount in the cloud and important."
"Sometimes, we have sync-up issues where the build doesn't get processed due to these sync issues, causing the build to fail. That's one of the drawbacks I see. When we did a huge sync-up, we faced a couple of issues. It takes some time for us to complete the sync-up. For frequent, smaller updates, we haven't had any issues. However, challenges can arise for those who prefer doing everything in one go. This might not necessarily be due to the tool itself but because of the approach of doing everything in a single batch."
"I want to see if new architectures have been incorporated in Docker or if we have to wait for another release."
"I would like to see a more UI-based tool so that students can easily understand it rather than memorizing all of the Docker commands."
"Sometimes, it can become heavy and cause performance issues."
"I think Docker can improve as it relates to overall stability."
"The lack of native support for billing and self-service capabilities is an area Kubernetes could improve. This requires the use of third-party integrations or managed services in order for customers to be able to deploy clusters on their own. It would be beneficial to have these features built-in into the Kubernetes platform."
"The solution lacks some flexibility."
"The tool needs to improve its UI. The tool is very complex and basic."
"The front end is very rudimentary."
"Setup was not straightforward."
"Although we face issues when migrating to new versions of Kubernetes, such as misunderstandings on using new features or integration with proxy services, these issues can be addressed with proper preparation."
"Management features could be simplified."
"In the financial service sector, I'd rate scalability an eight out of ten. But do it in a controlled manner, not auto-scaling. If your application has a bug and you enable the autoscaler, it will spike your costs. If someone deploys an application with a bug, that's automatically a problem."
 

Pricing and Cost Advice

"Docker is open source. To use a Docker enterprise model, we would need to pay for it."
"Pricing is based on the number of users."
"We are using the open-source version of the solution."
"We use the open-source version."
"The pricing of the solution is fairly cheap."
"The current cost for us is nothing as an open source."
"Docker is a free open-source solution. However, there is the Docker Enterprise which is a paid solution."
"The solution offers an open-source version that is free and includes a lot of functionality."
"We use the solution's open-source version."
"Kubernetes is open source. But we have to manage Kubernetes as a team, and the overhead is a bit high. Compared with the platforms like Cloud Foundry, which has a much less operational overhead. Kubernetes, I have to manage the code, and I have to hire the developers. If someone has a product, a developer should know exactly what he's writing or high availability, and all those things may differ the costs."
"It's an affordable solution"
"The solution is open source and has no fees."
"Pricing isn't a major concern for us. Since we resell Kubernetes services and focus on providing support, integration, and education, we don't usually have pricing issues. Our customers are more concerned with getting the right support and services than the cost. So, the value we provide is more important than the actual pricing. Pricing might change in the future, but it’s not a big issue for us right now."
"The solution requires a license to use it."
"I would say the solution is worth the money, but it depends on the required workloads, the type of workload, and the scaling requirements etc."
"Microsoft provides reasonable costs for Kubernetes."
