Measuring Cloud Storage Performance: Blocks vs. Files

What are some good reasons to adopt cloud storage? Cost, durability and flexibility. So let me talk about performance, instead. Look at this graph: As part of our daily testing, we do routine performance measurements across a broad swath of cloud storage providers. It gives us a check to ensure that the various CloudArray subsystems […]

Measuring Cloud Storage Performance

There are many excellent reasons to use cloud storage, but fast and efficient transfer of large amounts of data isn’t usually listed as a benefit. That’s one of the reasons why people use cloud storage gateways: to speed up cloud storage access. Recently, I realized we’ve never published any details on the performance gains that […]

Clouds, Consistency, and Progress Bars

I have the bad habit of staring at progress bars. I was backing up my Mac laptop to a CloudArray volume.¹ With gigabit ethernet, a full backup to a CloudArray volume takes less time than my local USB drive. Apple’s Time Machine actually only does a full backup once, followed by hourly incrementals that are […]

The API is not the Cloud

“If we’re not using the APIs, we aren’t using the cloud.” That’s what he said, and that’s what I can convince myself to believe every other Tuesday. (That’s when I like to exercise my self-skepticism.) What’s the context? I was involved in a discussion with a prospect implementing a private cloud, and he was dead-set […]
