Zoom selects Oracle as a cloud infrastructure provider for its core online meeting service

Zoom selected Oracle Cloud Infrastructure for its advantages in performance, scalability, reliability, and superior cloud security. Oracle’s pioneering use of off-box network virtualization removes the “hypervisor tax” common in first-generation clouds.


We recently experienced the most significant growth our business has ever seen, requiring massive increases in our service capacity. We explored multiple platforms, and Oracle Cloud Infrastructure was instrumental in helping us quickly scale our capacity and meet the needs of our new users.

Business challenges

In April, as working from home became a global health imperative, Zoom’s daily tally of meeting participants mushroomed to 300 million, up from 10 million in December. One reason for that growth spurt was that the company, founded in 2011 with a focus on business users, had begun supporting educators and students with a free tier for K–12 schools. Zoom becoming an essential service for enterprises further boosted its usage.

Video communications has become an essential part of our professional and personal lives, and Zoom has led this industry’s innovation.

In just nine hours, Oracle’s engineering team took Zoom from deployment to live production—with enough capacity to meet the surge of new users. Oracle Cloud Infrastructure initially supported hundreds of thousands of concurrent Zoom meeting participants. Within weeks, the number had grown to millions, and Zoom was able to smoothly scale to meet that need.

Already, Zoom is transferring upwards of seven petabytes (1015 bytes) through Oracle Cloud Infrastructure servers each day, roughly the same capacity in a day that would be needed to stream HD video for 93 years.
