In August 22, 2024, Marc Olson shared insights into the evolution of Elastic Block Store (EBS) at AWS. EBS started in 2008 as a simple block storage service but has grown to deliver over 140 trillion operations daily. The journey involved transitioning from HDDs to SSDs, tackling noisy neighbors, and making incremental improvements across the stack. By dividing the development team into smaller focused groups, EBS was able to address performance issues effectively. The post highlights the importance of challenging assumptions and continuously measuring and managing system performance to meet customer needs in the ever-evolving landscape of cloud storage.
