Pese painokura sisitimu yako, traffic inowedzera, vashandisi vazhinji vanoshandisa zvigadzirwa zvako, maseva anotanga kupindura zvishoma nezvishoma, nguva yekuderera inomanikidza bhizinesi rako kutambura wobva watanga kufunga nezve kuyera.  Pane nzira mbiri dzekutanga dzekuyera - vertical uye horizontal.    inotarisira kuwedzera simba rehurongwa nekuwedzera kazhinji CPU, uye RAM kumaseva ako. Vertical scaling  Mukupesana,   kunotarisa pakudzokorora (kana cloning) maseva ako mudziva rezviwanikwa. kuyera kuyera   Zvimwe pane izvi:  Vertical scaling  Vertical scaling ndiyo yakanakisa sarudzo kune yakaderera-traffic sisitimu nekuti ndiyo nzira inosvikika yekubata kukura pasina kuunza kumwe kuoma.

Horizontal scaling Load balancer    inogovera traffic pamaseva ako uchishandisa   akadai se: A load balancer chaiwo algorithms   Round-robin   Weighted round-robin  IP hash-based approaches  Kashoma yekubatanidza nzira  Weighted shoma yekubatanidza nzira  Nzira shoma yekupindura,  nezvimwe zvakawanda.   Kunyange zvakadaro, ine zvipingamupinyi zvakawanda:  Masevha anofanira kunge asina nyika  Zvirongwa zvinofanirwa kuenderera muchitoro che data  More complicated  zvingadiwa   kuendesa mazano  Mutoro unoremerwa unogona kuita bhodhoro rekuita kana rikasagadziriswa uye zviwanikwa zvisina kukwana  Inounza kuwedzera kuomarara kune sisitimu uye inomira senge ingangoita imwe pfungwa yekutadza, iyo inoda kushandisa failover mazano.
