Opta Information Intelligence
Processing half a trillion data links in days, not months
Opta needed to process massive datasets for their information intelligence platform. Their original infrastructure took 80-90 days to run half a trillion links across 70 nodes. After migrating to a high-performance cloud platform, they achieved the same results in just 3 days.
"On our first attempt we ran half a trillion links across 70 nodes which took about 80-90 days. Since we moved to the new platform, it only takes 3 days!"

Cutting hosting costs in half while scaling 6x
Vanilla Forums powers online communities for brands like Electronic Arts, HootSuite, and Adobe. As they grew, public cloud costs became unsustainable. By switching to a private OpenStack cloud, they slashed hosting bills by nearly 50% while growing their infrastructure 6x with the same small ops team.
"Right out of the gate we cut our hosting bill nearly in half by switching to a private cloud. It's been much more stable than our public cloud VMs were."
