Extract from Reveal’s article “eDiscovery Deployment Options: Processing at Source vs. Cloud”
Most organizations do not lose a litigation matter because they lack data. They lose because they cannot control it: where it lives, how fast it can be processed, and whether moving it creates more legal exposure than the case itself. That is the real tension driving today’s conversation about eDiscovery deployment options.
As data volumes grow and regulatory environments tighten, choosing between processing data at source (on-premises or private infrastructure) and migrating it to a shared or public cloud is no longer a purely technical decision. It is a strategic one with direct implications for litigation readiness, data sovereignty compliance, cost predictability, and organizational risk.
What Are eDiscovery Deployment Options?
eDiscovery deployment options refer to the infrastructure models organizations use to collect, process, review, and produce electronically stored information (ESI) in response to litigation, regulatory inquiries, or internal investigations, as defined by the Electronic Discovery Reference Model (EDRM). The two primary models are: (1) cloud-based eDiscovery, where data is uploaded to and processed in a vendor-hosted cloud environment; and (2) processing at source (also called on-premises or private deployment), where eDiscovery workloads run within the organization’s own infrastructure or a dedicated private instance. According to Gartner’s Legal and Compliance Technology research, each model carries distinct trade-offs in security, scalability, cost, and compliance.
