Quantum ActiveScale Automatically Meets Strong Consistency Requirements for Amazon S3 Compatibility News provided by Share this article Share this article SAN JOSE, Calif., Dec. 10, 2020 /PRNewswire/ -- Quantum Corp. (NASDAQ: QMCO) today announced that its ActiveScale ™ object storage platform automatically complies with the new strong consistency requirements for compatibility with Amazon Simple Storage Service (S3) applications. To claim AWS S3 compliance following the recent S3 update, object storage systems must ensure strong consistency. Strong Consistency and Why It Matters Strong consistency refers to the availability of data objects in distributed storage systems. As many applications require that data is written and immediately read back, strong consistency ensures that the latest version of the data is immediately presented to the application with no impact on performance. All metadata instances are updated simultaneously so that the data is presented in a consistent state, no matter which node in a distributed cluster a request is sent to. Without this capability, data requests that go to a different node from where it was originally written are likely to return inaccurate data or result in the system being unable to locate the data at all.
