Speaker: Jay Runkel, Principal Solution Architect, MongoDB Speaker: Jayson Hurd, Comcast Level: 200 (Intermediate) Track: Operations Comcast is pioneering private-cloud initiatives to bring velocity, elasticity, and self-service to its internal customers. For databases, this means providing the infrastructure and tooling to support a DevOps model enabling application teams to request/provision, monitor, backup, upgrade, and tune their own environments. Using this approach, an extremely small operations team can manage a large number of applications and servers. We will discuss the business goals of velocity, elasticity and self-service, outlining the hidden benefits of this approach. The technical and process architectures will then be explored in detail, demonstrating how a recipe of IaaS, web, Ansible, and MongoDB Ops Manager are used to provide an automated self-service DBaaS platform. What You Will Learn: - How to leverage Ops Manager to support a self-service DevOps model. - Establishing requirements for your own MongoDB as a Service platform. - Best practices for building a DBaaS for MongoDB.
