How does Zscaler leverage public clouds for its services?

Zscaler utilizes public clouds to ensure high availability and scalable performance. By leveraging the vast infrastructure of public cloud providers, Zscaler can distribute its services globally, thereby reducing latency and improving the user experience. The use of cloud resources allows Zscaler to scale its services dynamically based on demand. This means that as more users connect or as bandwidth requirements change, Zscaler can allocate resources in real-time to maintain optimal performance without the constraints of physical hardware.

The approach of relying on public cloud infrastructure also allows Zscaler to provide redundancy and resilience in its services. By not tying its performance to a single physical location or dedicated server, Zscaler can quickly adapt to changes in traffic or unexpected outages, further enhancing its service reliability for users. This combination of high availability and scalable performance is a cornerstone of Zscaler's offering, enabling customers to benefit from seamless access to secure internet resources regardless of their location.
