Apparatuses and methods for a distributed message service in a virtualized computing system

A computing node cluster, comprising one or more processors and memory configured to cause the computing node cluster to host:

• a virtualized file system including a virtual disk configured to store messages for a message topic;
• a broker logically allocated to the message topic, wherein the broker is configured to cause a message directed to the message topic provided from a publisher to be stored at the virtual disk, wherein the broker is further configured to route the message to a subscriber of the message topic that is registered with the broker;
• and
• an operating system configured to manage the virtualized file system, the operating system including a message service configured to manage logical allocation of the broker and manage allocation of the virtual disk to the message topic, wherein, in response to failure of the broker, the operating system is configured to instantiate a new broker that is logically allocated to the message topic.

A method, comprising:

• receiving, from a publisher, a first message directed to a first partition of a message topic at a first message service hosted on a first computing node of a computing node cluster;
• storing, via a broker of the first message service that is logically allocated to the first partition of the message topic, the first message at a first partition of a virtual disk of a virtualized file system hosted on the computing node cluster;
• receiving, from the publisher, a second message directed to a second partition of the message topic at a second message service hosted on a second computing node of the computing node cluster;
• and
• storing, via a broker of the second message service that is logically allocated to the second partition of the message topic, the second message at a second partition of the virtual disk;
• and
• in response to failure of the broker of the first message, instantiating a new broker of the first message service that is logically allocated to the first partition of the message topic.
