Disaster Recovery (DR) planning is crucial to any business and especially service providers such as NTT, whose core business is based on SLA’s. Replication which is the simple concept of copying data from one system to another across sites, has matured over the years, providing better Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for DR. In this session, we will show how OpenSDS is enabling replication for Kubernetes clusters across sites and can scale out to match the needs of cloud-native applications. Besides, we will talk about DR planning at NTT - architecture and design, RTO and RPO and other requirements, and consideration in adopting OpenSDS scale-out data replication and other replication technologies.
