Amazon FSx for Lustre, a fully managed service that makes it easy and cost effective to launch, run, and scale the world’s most popular high-performance file system, now supports project quotas. With project quotas, you can group multiple files or directories on your file system into a project, and monitor storage consumption on a per-project basis. Project quotas are ideal for storage administrators who manage file systems that serve multiple projects or teams who want to ensure that no project exceeds its allocated storage capacity.
