In terms of the impact of container orchestration, I would say that though my company does not currently use a lot of containers, we plan to move to containers. I recommend others to just use the internet than ChatGPT since mostly all issues are already known and very easy to deal with so it is better to use the knowledge from the industry. In terms of the use of Docker for AI projects or workflows, I would say that my company deploys AI applications on Docker, like any other application and pipeline. The tools or practices that have proven to be the most beneficial for our company's AI initiatives are agnostic to Docker. There is nothing special in Docker, and our company just uses it to deploy applications. The value derived from the use of the product revolves around the scalability and the reliability it offers. The product helps with the cost-savings part since it saves time and money linked with the amount of engineers required to spend time on operations. I rate the solution a nine out of ten.

Our company uses the solution for the production environment, web projects, and hosting services. For example, we use it to host an NGINX box manager with proxy, reverse proxy, and DNS server. We host a bunch of web services for clients and deploy both on-premises and on the cloud. Several of our…

Overall, setting up the Docker environment is quite easy. Many methods exist, such as using Docker Compose and Docker networks to communicate between containers. The main challenge lies in designing the architecture and integrating different frameworks and microservices. I would rate the ease of setting up the tool at around nine out of ten. The time it takes to deploy depends on the scale of the system. For the early-stage startup I'm currently working with, it doesn't take much time. It's just me handling the deployment. In our early-stage startup, we have a couple of teams with around four to five backend APIs and two front-end services. Deploying these doesn't take much time. My focus is more on minimizing costs due to our lean startup structure.

Key learnings from peers

Valuable Features

Docker's most valuable features include security, detailed documentation, ease of use, fast learning curve, internal DNS, and the overlay network for orchestration. It is highly customizable, supports auto scaling and auto healing, provides a dedicated QA environment, and integrates well with other solutions. Docker is lightweight, portable, and offers excellent resource utilization, stability, and modularity. It facilitates quick deployment, containerization, and efficient management of dependencies and environments, making it user-friendly and cost-effective.

"We use Docker to facilitate deployment, updates, and management."
"It is a quite mature technology."
"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."

Room for Improvement

Docker needs better documentation, enhanced security features, improved stability, and more user-friendly interfaces. Users also desire easier image creation, better Windows integration, and advanced management tools. Troubleshooting within containers, optimizations for performance, and comprehensive tutorials are necessary. Many suggest incorporating GPU support, simplifying orchestration, and providing monitoring tools. Pricing adjustments and enhanced AI capabilities are also recommended for a smoother experience.

"Enhancing artificial intelligence capabilities and cluster management should be a priority. It should facilitate some security management."
"Docker volumes. When I integrated volumes, I faced challenges. I have not essentially used add volumes to the existing instances."
"Sometimes there's a bug or defect in the solution. However, the Docker team works on fixing it."

ROI

Organizations experienced significant ROI from Docker due to reduced development and deployment times, cost savings, and improved efficiency. Docker's ease in provisioning environments, aligning with business requirements, and solving deployment issues contributed greatly. They noted Docker's ability to enhance productivity, streamline workflows, and ensure consistent builds across different environments. Additionally, running applications efficiently on smaller hardware added to the value, providing substantial returns.

Pricing

Docker offers a free open-source version ideal for many companies, but Docker Enterprise requires a paid license. Licensing costs vary, with an enterprise license around $24 per user per month, and smaller licenses costing $9 or $5 per user. When technical support or enhanced scalability is needed, additional costs may apply. Users generally find Docker cost-effective and affordable, though larger organizations may face higher expenses with multiple users and additional services.

"The offering and service are quite free."
"It's an open-source solution, so it doesn't cost anything"
"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."

Popular Use Cases

Docker is utilized primarily for deploying and managing microservices, developing dev stacks, CI/CD pipelines, containerizing applications, and creating secure environments. It facilitates quick setup for testing, building, and shipping applications across various platforms like AWS and Azure. Docker Swarm and Kubernetes orchestration, along with containerization for web applications, cloud solutions, and enterprise-grade applications, are key aspects. Organizations leverage Docker for its isolation, resource efficiency, and improved deployment processes in diverse environments.

Service and Support

Docker's customer service and support are considered good, with comprehensive documentation and an active community. Many rely on community forums and online resources instead of contacting support directly. The support experience varies based on the subscription plan, with licensed users receiving priority and 24/7 technical assistance. Users rate customer support highly, noting that issues are generally solvable through documentation and forums. Some improvements in responsiveness are desired.

Deployment

Most users find Docker's initial setup easy and straightforward, with many mentioning that it can be done within minutes. Some state that a basic understanding of containerization is helpful. Experiences with Mac and Windows can vary slightly, with Windows setups occasionally presenting challenges. Docker documentation is praised as comprehensive, and having prepared images speeds up the process. For some, deployment may take longer based on network configurations and specific application needs.

Scalability

Docker is largely scalable, but automation is lacking, requiring manual container scaling. Many organizations highlight its effective scalability, accommodating thousands of users. Docker's integration with tools like Kubernetes enhances this capability. However, some experience scalability challenges without additional tools, rating it lower. Generally, Docker easily scales applications, is used extensively across various company sizes, and its horizontal scaling works well. Overall, most feedback rates Docker's scalability positively, ranging between six and ten out of ten.

Stability

Docker's stability is largely rated highly, with many assessing it between eight and ten out of ten. Users note it as reliable and performant, though some mention occasional issues with container crashes and memory management. Security vulnerabilities are a concern for a few, but many find Docker stable for Linux, seeking improvements for Windows. High integration capabilities are appreciated, despite some difficulties with specific base images. Users often highlight its positive impact on project workflows.
