When running fast, it's easy to trip — many businesses struggle when success forces them to scale rapidly. Scalability is a vital consideration when purchasing or building infrastructure as foundational systems that can't scale become hurdles instead, resulting in lost momentum and expensive replatforming. Business leaders need to understand the different dimensions of scale to ensure that the infrastructure they choose allows them to run at full speed, encompassing administrative, functional, and load scalability. Choosing platforms that address these varied challenges can help future-proof a business, with extensible solutions being more likely to meet current and future needs.
