**Horizontal Scaling** refers to provisioning additional [[dido:public:ra:xapend:xapend.a_glossary:s:server|servers]] to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional [[dido:public:ra:xapend:xapend.a_glossary:i:instance|instances]] instead of moving to a larger instance size.
