Stop Overpaying for GP2: GP3 Cost & Performance Explained

Most people still use GP2 as the default EBS volume type in launch templates and infrastructure modules. Not because it is optimal today, but because it has been there for years. In most production audits I review, oversized GP2 volumes are one of the easiest cost optimizations left untouched. GP2 performance is tied to volume size and burst credits, which can lead to unstable latency and throughput during sustained workloads. For production databases, search clusters, and write-heavy services,
