Scale-Up Architecture

Scale-up architecture refers to a design approach where a system's capacity is increased by adding more resources to a single machine, rather than distributing the load across multiple machines. This can mean upgrading the existing hardware, such as adding more memory or faster processors. It's like enhancing a car's engine to make it faster instead of buying multiple cars. While it can be simpler to implement because it involves fewer components, it may have limits on how much you can scale, so businesses often balance this with scale-out architecture, which spreads workloads over many machines.
