tiered storage
A layered structure of performance levels, or tiers, that matches data
access requirements with the appropriate performance tiers. The tiers
are:
Tier 1: Static content. Tier 1 is fully supported computing expected to
be production quality.
Tier 2: Application logic. Tier 2 platforms are not supported by the
security officer and release engineering teams. Tier 2 systems are
targeted for Tier 1 support, but are still under development.
Tier 3: Database. Tier 3 platforms are architectures for which hardware
is not or will not be available or that are considered legacy systems
unlikely to see broad future use.
