Packages that use Constraint

Package	Description
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.
com.eqixiac.equinix.design.resilience	Failure analysis of a design.
com.eqixiac.equinix.design.spi	Extension points of the design engines.

Uses of Constraint in com.eqixiac.equinix.design.constraint

Classes in com.eqixiac.equinix.design.constraint that implement Constraint

Modifier and Type	Class	Description
final class	BudgetConstraint	The expected monthly cost must not exceed commercial.budgetMaxMonthly.
final class	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.
final class	EveryMetroUsedConstraint	Every metro of a design must carry a workload (primary or standby) or a cloud connection.
final class	ExcludedMetrosConstraint	No metro in constraints.excludedMetros may be used.
final class	ExcludedRegionsConstraint	No metro may be in a region of constraints.excludedRegions.
final class	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).
final class	MaxSiteLatencyConstraint	Every site's round trip to its nearest portfolio metro must be within constraints.maxLatencyMs.
final class	MetroCountConstraint	constraints.minMetros and constraints.maxMetros.
final class	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.
final class	PinnedWorkloadsConstraint	Every workload with a pinnedMetro needs that metro in the design.
final class	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).
final class	RequiredMetrosConstraint	Every metro in constraints.requiredMetros must be part of the design.
final class	RequiredRegionsConstraint	The design must have at least one metro in every region of constraints.requiredRegions.
final class	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.

Methods in com.eqixiac.equinix.design.constraint that return types with arguments of type Constraint

Modifier and Type	Method	Description
static List<Constraint>	Constraints.forSpec(DesignSpec spec)	The built-in constraints for a spec: one per field of DesignConstraints that is set, the workload rules (pinned metro, per-workload latency, cloud reachability) when the spec has workloads or required clouds, the budget when one is stated, and EveryMetroUsedConstraint always.

Uses of Constraint in com.eqixiac.equinix.design.resilience

Classes in com.eqixiac.equinix.design.resilience that implement Constraint

Modifier and Type	Class	Description
final class	FailoverGeoZonesConstraint	"geo_zones_failover": data sovereignty that holds through failover.
final class	MinSurvivalConstraint	"min_survival": a portfolio must keep at least a minimum share of its baseline service through its worst single-element failure (see N1Survival).
