Simplicity
Docker Swarm is easy to set up and use, especially for those already familiar with Docker. It integrates seamlessly into the Docker ecosystem, providing a straightforward solution for container orchestration without the need for additional tools.
Native Docker Integration
Swarm is built into Docker, meaning that Docker users do not need to install or configure another orchestration tool. This provides a consistent experience from development to production.
Declarative Service Model
Swarm allows users to define the desired state of their services, and the system works to maintain that state. This includes scaling services up or down, and handling load balancing.
Easy Scaling
Docker Swarm makes it easy to scale applications horizontally by simply changing the number of replicas of a service. The platform manages the distribution of these replicas across the available nodes.
Built-in Load Balancing
Swarm includes built-in load balancing, distributing incoming client requests to running containers based on task states and node availability.
Docker Swarm is a good choice for small to medium-sized deployments where ease of setup and tight integration with Docker are priorities. However, for larger, more complex environments or when advanced features like custom scheduling and multi-cloud support are necessary, other orchestration tools like Kubernetes might be more appropriate.
We have collected here some useful links to help you find out if Docker Swarm is good.
Check the traffic stats of Docker Swarm on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Docker Swarm on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Docker Swarm's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Docker Swarm on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

Docker Swarm Classic (https://github.com/docker-archive/classicswarm) is dead. Docker Swarm Mode is alive, and I know some people use it, but it's very niche compared to k8s. As someone who interacts with k8s regularly, I often feel like there is a place for a simpler k8s alternative. But looking at history I see the attempts like Swarm fail. What do you think played the decisive role in the k8s victory? Features,... - Source: Hacker News / over 1 year ago

Docker Swarm is a container orchestration tool built right into the Docker CLI which allows us to deploy our Docker services to a cluster of hosts, instead of just the one allowed with Docker Compose. This is known as Swarm Mode, not to be confused with the classic Docker Swarm that is no longer being developed as a standalone product. Docker Swarm works great with Appwrite as it builds upon the Compose... - Source: dev.to / about 5 years ago
Docker Swarm, a product originally developed by Docker, Inc., stands out as a lightweight container orchestration tool within the broader domains of developer tools, DevOps, containers as a service, and cloud computing. It functions by managing a cluster of Docker nodes, which allows for the deployment and scaling of containerized applications across distributed environments. Despite its utility, Docker Swarm occupies a niche segment, especially when compared to Kubernetes, the de facto leader in this space.
Public Opinions and Comparisons with Competitors
Docker Swarm often features in discussions as a notable alternative to more comprehensive solutions like Kubernetes and Rancher. It is praised for its ease of use, especially for those already familiar with Docker, as it integrates seamlessly into the Docker CLI and utilizes the Compose specification. This simplicity makes Swarm an attractive option for smaller organizations or projects seeking straightforward orchestration capabilities without the overhead of Kubernetes. However, it lacks the extensive community support, feature set, and extensibility that Kubernetes offers, which are crucial for larger, more complex deployments.
In the competitive landscape, Docker Swarmโs value proposition has traditionally been its ability to transform multiple Docker instances into a single virtual host. This feature contributes to its prominence as one of the most popular container orchestration tools following Kubernetes. The comparative simplicity of Docker Swarm is frequently cited as a benefit for developers looking for a less complex alternative to Kubernetes, particularly when managing smaller clusters.
Challenges and Market Position
Despite these advantages, Docker Swarm faces significant challenges. The decision to delegate support and development to Mirantis has led to stagnation in its feature advancement, leading to a perception of deprecation. This perception is exacerbated by the lack of a clear monetization pathway for Swarm, which diminishes incentives for further development and innovation.
Furthermore, Docker Swarm Classic has been officially deprecated, with Swarm Mode continuing to exist as a feature within Docker. This dichotomy adds to the confusion among users regarding the future of Docker Swarm as an independent technology. Forums such as Hacker News reveal a consensus that Swarm falls short of competing with Kubernetes on grounds of features, openness, and extensibility, raising concerns about its long-term viability in a rapidly evolving ecosystem.
Conclusion
In conclusion, while Docker Swarm provides a straightforward, integrated solution for Docker users seeking container orchestration, its niche appeal, stagnant development, and lack of robust feature evolution restrict its broader adoption. Organizations still find value in Swarm's simplicity and ease of use, but it seems increasingly likely to remain a secondary choice to Kubernetes. The future trajectory of Docker Swarm will largely depend on contributions from the community and stakeholders like Mirantis, whose ongoing support will be critical for maintaining its relevance in the container orchestration space.
