Cloud computing facilitates scalability for startups by providing on-demand access to resources and allowing businesses to swiftly adjust their IT infrastructure to meet growing demands. Startups can utilize services such as Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) to scale up without the need for substantial initial capital investment in hardware. This elasticity enables them to manage fluctuations in user traffic and quickly deploy new features or applications. Moreover, the cost-effective billing models typical of cloud services help startups optimize operational expenses and strategically allocate funds for growth initiatives.
