GeneralPrinciplesoftheClusterPlanThefollowingaresomegeneralprinciplestobeawareofwhenconfiguringtheclusterplan:

DesignedforConsistency

RabbitMQclusteringisnotprimarilyasolutionforincreasedavailability.Instead,itisdesignedforconsistencyandpartitiontolerance,asdescribedintheCAPtheorem .RabbitMQclusteringprovidesincreasedmessageconsistencythroughqueuemirroring.Thismeansthatmessagesaccessedinonequeueareexactlythesameasinanotherqueue.Formoreinformation,seeConsistencyorAvailabilityTradeoff.

Otheroptionscanbeusedforavailabilityrequirements,suchastheuseoffederationbetweenexchangesorqueues.

ForadetaileddescriptionofdistributedRabbitMQbrokers,seetheRabbitMQdocumentation .

NumberofNodes

Everynodeintheon-demandclustermaintainsacompletedatabaseofallmetadata,andallchangestothemetadataareconfirmedbyeverynodeinthecluster.Therefore,goingbeyondsevennodescanhaveasignificantnegativeimpactonperformance.Foroptimumresilienceandperformance,Pivotalrecommendsthreenodesformostworkloads.

NetworkLatency

RabbitMQclustersareonlyrecommendedfordeploymentinlowlatencynetworks,whichnormallymeansthatitisnotadvisabletodeploytheseclustersacrossavailabilityzones(AZs).ThestabilityandperformanceoftheRabbitMQclusterisheavilyinfluencedbytheworkloadonthenodes,replicationchoices,andnetworklatency.

Forthisreason,PivotalrecommendsthatyoudeployRabbitMQclustersintoasingleOpsManagerAZ.However,wheredifferentAZsareinthesamedatacenter,withreliablelowlatencylinks,spanningAZscanbeused.

ForcloudIaaSdeployments,Pivotaldoesnotrecommendthatdeploymentsspanregions.Forexample,inAmazonWebServices(AWS)terms,deployingaRabbitMQclusteracrossAZswithinaregionshouldprovidehighenoughnetworkperformancetopreventimpactingclusterstability.However,deployingacrossAWSregionsislikelytoleadtoclusterinstability.Formoreinformation,seetheAWSdocumentation .

ConsistencyorAvailabilityTradeoffInadistributedmessagingsystem,atradeoffmustbemadebetweenavailabilityorconsistencywhenanetworkpartitioneventoccursandoneormorenodesarenotabletocommunicatewitheachother.TheclusterplanletsoperatorsdecidehowtheywanttheRabbitMQclustertoreactintheeventofanetworkpartition.

Pivotalrecommendskeepingthedefaultclusterpartitionoptionof pause_minority becausethissatisfiesmostusecases.Choosingthe pause_minority

partition-handlingstrategyfavorsmessageconsistencyoveravailability.Formoreinformationabouttheoptionsforhandlingpartitions,seetheRabbitMQdocumentation .ForadetaileddescriptionoftheoptionsavailableinRabbitMQforPCF,seeClusteringandNetworkPartitions.

Hereisanexampleofhow pause_minority works.IfyoucreateaRabbitMQclusterwiththreenodesandonenodebecomesunabletocommunicatewiththeothertwo,thisnodeisintheminority.Thenodethatisintheminorityispaused,andtheothertwonodescontinueservingtraffic.Ifeachofthenodeslosesconnectivitywiththeothertwo,thentheentireclusterispausedtopreservedatasincenomajoritycanbeestablished.Theclusterhealswhentwoormorenodesareabletocommunicatewitheachother.

RabbitMQQueueAvailabilityItisimportanttobeawarethatmessagequeueavailabilityisdifferentfromclusteravailability.So,havingclusteravailabilitydoesnotmeanthatallofthemessageswithinthequeuesarealsoavailable.

Bydefault,queueswithinaRabbitMQclusterarelocatedonasinglenode—thenodeonwhichtheywerefirstdeclared.However,queuescanbeconfiguredtomirroracrossmultiplenodes,sothatanymessagepublishedtothequeueisreplicatedtoallmirrors.Enablingmirroringcanhaveanegativeimpactonqueueperformancebecausemessagesmustbecopiedtoallmirrorsbeforebeingacknowledged.

acknowledgedatthemaster.Queuemirroringenhancesqueueavailability,butdoesnotdistributeloadacrossnodesbecauseeachoftheparticipatingnodesmuststilldoallthework.

Appdevelopersmustdecideiftheywanttousequeuemirroringanddeterminethepolicytheywanttoapplytotheirqueues.Thesechoiceshavesignificantimpactontheavailabilityoftheirqueues.Formoreinformation,seetheRabbitMQdocumentation .

Unlikethepre-provisionedplan,theclusterplandoesnotshipwithadefaultloadbalancer.Therefore,developersmustconfiguretheirapptousethearrayofhostsprovidedin VCAP_SERVICES .Ifdevelopersenablequeuemirroring,theymustalsoensuretheirappshavere-trylogicandreconnectionlogicthatiteratesovertherangeofhostsprovided.MostcommonRabbitMQclientshavethislogicbuiltintothem.Formoreinformation,seetheSpringAMQPdocumentation .

ManagingOn-DemandResourcesThroughPlansInconfiguringeachplan,thereareanumberofoperationalcontrolsthatplatformoperationsteamscanusetomanagetheresourcesconsumedbyon-demandRabbitMQ:
