Apache Mesos vs DC/OS: What are the differences?
Introduction
Apache Mesos and DC/OS are two popular distributed systems platforms used for managing large-scale data centers and running containerized applications. While both platforms offer similar functionality, there are key differences that differentiate them.
Architecture: The architecture of Apache Mesos is based on a master-slave design, where a Mesos master node manages Mesos slave nodes. In contrast, DC/OS builds on top of Mesos and provides additional features like service discovery, load balancing, and multi-tenancy. It introduces the concept of a DC/OS master, which coordinates multiple Mesos masters, making it more powerful and flexible for enterprise deployments.
User Interface: Apache Mesos primarily provides a command-line interface (CLI) and a web-based user interface (UI) called the Mesos web UI. On the other hand, DC/OS offers a more advanced web-based UI, the DC/OS dashboard, which provides a visually rich user experience, making it easier to navigate through the system and manage applications.
Application Management: Mesos focuses on managing and scheduling tasks and frameworks, providing a flexible framework for deploying applications. DC/OS, being built on top of Mesos, enhances application management by providing extended capabilities like app deployment, rolling upgrades, and scaling, making it easier to manage and monitor applications.
Service Management: DC/OS goes beyond Mesos' native functionality and offers more advanced service management capabilities. It introduces service definitions and allows users to deploy and manage services as first-class citizens, providing a declarative and easy way to create and manage long-running services.
Package Management: DC/OS includes a built-in package manager called the DC/OS Universe, which allows users to install and manage applications or services from a marketplace-like repository. In contrast, Apache Mesos does not have built-in package management, requiring users to manually manage and install applications.
Enterprise Features: DC/OS caters more towards enterprise needs by providing additional features like fine-grained ACL-based multi-tenancy, security, and high availability. It offers advanced authentication and authorization mechanisms, allowing enterprises to enforce secure access control and management policies.
In summary, Apache Mesos provides a foundational layer for resource management and scheduling, while DC/OS builds on top of Mesos and provides additional features like advanced user interface, application and service management, package management, and enterprise-grade features.
