MesosCon NA 2016

Framework authors attempting to write frameworks which encapsulate or administer stateful services often encounter difficulties mapping the resource offer stream provided by Mesos to the framework’s provisioning, maintenance and upgrade goals. For disparate frameworks: Cassandra, Kafka, HDFS we have adopted a declarative approach to address this mapping problem. This approach has also been applied successfully to different layers of the framework lifecycle. In particular, we have applied a declarative approach to the fault-tolerant fulfillment of reservation and persistent volume requirements, and to the overall maintenance and upgrade of frameworks.
