package com.eqixiac.equinix.design.constraint
The built-in hard limits of the Metro Optimizer: one small, pure Constraint per field of DesignConstraints, plus the workload rules, the single-currency budget and the every-metro-used rule. Constraints.forSpec(DesignSpec) picks the ones a spec needs.
  • Classes
    Class
    Description
    BudgetConstraint
    The expected monthly cost must not exceed commercial.budgetMaxMonthly.
    ComplianceZonesConstraint
    Every metro must be in a region that at least one zone of constraints.complianceZones allows (ComplianceZone.getAllowedRegions()): the design stays within the stated zones.
    Constraints
    Chooses the built-in constraints a spec needs, and shared helpers.
    EveryMetroUsedConstraint
    Every metro of a design must carry a workload (primary or standby) or a cloud connection.
    ExcludedMetrosConstraint
    No metro in constraints.excludedMetros may be used.
    ExcludedRegionsConstraint
    No metro may be in a region of constraints.excludedRegions.
    GeoZonesConstraint
    Data sovereignty: every metro must belong to at least one of constraints.geoZones according to the live catalogue's geoScopes/geoZones for that metro (matched case-insensitively; CH, AU, BR, JP, CA, US also match the corresponding geo scope).
    MaxSiteLatencyConstraint
    Every site's round trip to its nearest portfolio metro must be within constraints.maxLatencyMs.
    MetroCountConstraint
    constraints.minMetros and constraints.maxMetros.
    MinimumRedundancyConstraint
    constraints.minimumRedundancy as an explicit rule on the metro set (see RedundancyTier): fewest metros, fewest distinct regions, and for N_PLUS_1 two metros sharing a region.
    PinnedWorkloadsConstraint
    Every workload with a pinnedMetro needs that metro in the design.
    RequiredCloudsConstraint
    Every required cloud must be reachable from at least one metro of the design, and every workload must reach each required cloud it names from the metro it is placed in (a workload runs in one metro).
    RequiredMetrosConstraint
    Every metro in constraints.requiredMetros must be part of the design.
    RequiredRegionsConstraint
    The design must have at least one metro in every region of constraints.requiredRegions.
    WorkloadLatencyConstraint
    Each workload with a maxLatencyMs must be placed (by WorkloadPlacer) in a metro whose worst known round trip to any site is within the limit.
