Choosing on-premise vs cloud archiving
The right choice depends on cost, compliance, control preferences, and expected access patterns. Both approaches have strengths and trade-offs.
Consider these factors:
- Compliance and sovereignty: On-premise may be needed for strict data locality or regulatory reasons; cloud vendors offer region-specific controls and certifications too.
- Cost model: Cloud offers pay-as-you-go and lower upfront costs; on-premise can be cheaper at large scale but requires capital investment and maintenance.
- Scalability: Cloud scales elastically for unpredictable growth; on-premises scaling needs planning and procurement.
- Access and retrieval: Cloud archive tiers might incur retrieval fees and latency; on-premise systems can be tuned for predictable access.
Also compare vendor certifications (ISO, SOC), encryption, immutable storage options, and integration with existing workflows. Hybrid models are popular: keep recent or sensitive data on-premise while offloading cold archives to the cloud.
