How Salesforce Hyperforce Is Developed?

Hyperforce is a complete re-architecture of Salesforce's platform, built to be more flexible, scalable, and secure while maintaining the core principles of Salesforce's multi-tenant, metadata-driven platform.
Hyperforce has been designed to deliver all of Salesforce's apps, services, and systems on public cloud infrastructure. It's built on a scalable architecture that allows Salesforce to run on any public cloud, with a lower cost and higher compute capacity.
Development-wise, Salesforce used a lot of open-source technology to create Hyperforce. The core idea is to bring Salesforce to the data, rather than the data to Salesforce. So, they designed Hyperforce to be able to operate in data centers around the world.
To ensure security, Salesforce uses its existing methods like at-rest encryption, but they also add additional layers of security when they transport data to and from these public clouds.
