    12:15 - Persistent Storage with Kubernetes/ Openshift using Heketi - Ramakrishna Reddy, Contributor to Heketi

    Heketi ( provides a RESTful management interface which can be used to manage the life cycle of GlusterFS volumes. With Heketi, cloud services like OpenStack Manila, Kubernetes, and OpenShift can dynamically provision GlusterFS volumes with any of the supported durability types. Heketi will automatically determine the location for bricks across the cluster, making sure to place bricks and its replicas across different failure domains. Heketi also supports any number of GlusterFS clusters, allowing cloud services to provide network file storage without being limited to a single GlusterFS cluster

    Ramakrishna Reddy, Ramky  is currently a Principal Engineer with Red Hat with the Storage Engineering Group. He is also a contributor to the Fedora Project.  Prior to Red Hat, he was an Independent Consultant, consulting in the Natural Language Processing, Machine Translation, Indic Text processing.

At present, facilities provided by Apache Storm to access logs are limited. Logs are also stored locally, often resulting in loss. This talk is  about a system built using Rsyslog and Elasticsearch that aggregates logs real time and provides querying and visualization capabilities.

    Karri is working as a Production Engineer in Grid Ops team at Yahoo!. Grid Ops team provides Hadoop, HBase and Storm as a service to rest of teams at Yahoo! and he works on dealing with various operational and scaling problems associated with them.
