Fixed Capacity Provisioning
Fixed Capacity Provisioning is a resource allocation strategy where computing resources (such as servers, storage, or network bandwidth) are pre-allocated in fixed, predetermined amounts based on anticipated peak demand, rather than scaling dynamically. This approach involves provisioning infrastructure to handle maximum expected workloads upfront, often leading to over-provisioning to ensure availability during traffic spikes. It contrasts with elastic or on-demand provisioning models where resources scale automatically based on real-time usage.
Developers should learn and use Fixed Capacity Provisioning in scenarios where predictable performance, compliance with strict SLAs (Service Level Agreements), or legacy system constraints are critical, such as in financial trading platforms, healthcare systems, or government applications requiring guaranteed uptime. It is also relevant when dealing with applications that have stable, well-understood traffic patterns, as it can simplify cost management and avoid the complexity of auto-scaling configurations, though it may lead to higher costs due to idle resources during off-peak periods.
