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.

The volumes for persistent storage could be more user friendly right out of the box. I would like an option to just use it as local storage or some kind of NSF or CIF. Or to mount the volume straight to a Google Drive or through a particular cloud storage. It's not that these things are impossible, but you have to do some extra work or configurations.

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

Last updated Nov 8, 2024

Valuable Features

Docker offers valuable features like security, detailed documentation, ease of use, and fast learning. The overlay network for container orchestration, integration with other solutions, quick deployment, containerization, and portability are highly appreciated. Customization, load balancing, auto-scaling, resource efficiency, and isolation between environments are significant benefits. Docker's flexibility, scalability, fast deployment times, resilience, and independence from the underlying system enhance its attractiveness to various users.

"Docker is highly scalable."
"The ability to use an image with the software built into it, rather than just the software, is beneficial."
"We use Docker to facilitate deployment, updates, and management."

Room for Improvement

Docker faces challenges with stability and security, requiring improvement in documentation and tutorials. Users request better firewall management, GPU capabilities, and pre-deployed multi-container solutions. There's demand for intuitive user interfaces, quicker deployments, and improved Docker Swarm integration. Docker's pricing, support, and integration with Windows need enhancement. Some users experience performance issues and need simpler image manipulation. Improved tools for debugging and monitoring, along with advanced features and AI enhancements, are desired.

"There can be challenges with port mapping, however, that's not related to Docker itself."
"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."

ROI

Users report Docker facilitates faster development and deployment, significantly reducing time and staffing needs. It enhances ROI by providing a free open-source version and delivering high efficiency with consistent builds across environments. Docker increases productivity, simplifies workflows, and extends cost-effectiveness, especially in repeatable environments. It streamlines software dependencies and infrastructure by using smaller hardware efficiently. Docker aligns services quickly with business objectives while simplifying deployment compared to EC2, offering substantial cost savings and substantial ROI.

Pricing

Docker offers a cost-effective, open-source solution widely used for free, but the Enterprise version requires a paid license. Enterprise pricing can be $24 per user per month, with smaller plans costing $9 or $5 per user. Organizations may face additional costs for features like Docker Swarm and support. While some view it as affordable, others consider alternative solutions due to new licensing fees. Overall, Docker remains popular due to its efficiency and ease of use.

"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 primarily used for deploying and managing applications in containerized environments such as Kubernetes. Many use it for building images for microservices and UI applications, enhancing security, deploying web applications, simplifying cloud solutions, and managing DevOps pipelines. It serves as an efficient tool for containerization, offering quick deployment and scalability. Various users emphasize its use in creating development environments, fostering microservices architecture, and managing network resources.

Service and Support

Many users find Docker's customer service and support satisfactory, with strong documentation and community resources often resolving issues without direct contact. The availability of information online and user forums proves helpful. Those needing support rate it between seven to eight. More advanced support is tied to specific licensing packages, and professional support is globally available 24/7. Users also mention good experiences with technical support, though responsiveness could sometimes improve.

Deployment

Docker's initial setup is generally easy and quick, often taking just minutes. Users report a straightforward process, especially on Linux, with some challenges on Mac and Windows due to networking issues. The availability of Docker Hub facilitates the process by providing necessary container images. Installation requires minimal technical knowledge, supported by comprehensive documentation. Docker's setup phase is highly efficient for those with basic containerization understanding, although more complex deployments may pose challenges.

Scalability

Docker is generally scalable, effectively supporting large user bases when configured properly. However, it requires manual vertical scaling and benefits from integration with tools like Kubernetes for enhanced scalability. Users appreciate Docker's capability to manage numerous applications simultaneously, although some note the lack of built-in autoscaling features. Docker is popular across various sectors and is often utilized for its efficient handling of containerized applications, accommodating thousands of users without significant issues.

Stability

Users generally find Docker stable, with many rating it between eight to ten out of ten for reliability. While Linux compatibility and performance are praised, Windows can have occasional issues. Some note memory management as a concern. Docker excels in providing a consistent environment, though security tools may be needed to handle vulnerabilities. Users appreciate its ability to isolate containers, ensuring stability and minimal impact across services, although memory and integration downtimes can occur.
