Zscaler Private Access (ZPA) enables organizations to provide access to internal applications and services while ensuring the security of their networks. ZPA is easier to deploy, more cost-effective, and a more secure alternative to VPNs. Unlike VPNs, which require users to connect to your network to access your enterprise applications, ZPA allows you to give users policy-based secure access only to the internal apps they need to get their work done. Business Continuity for ZPA is powered by Private Cloud Controllers, which are deployed as a software package in enterprise data centers, local private cloud environments such as VMware, or public cloud environments such as Amazon Web Services (AWS), Microsoft Azure Cloud, or Google Cloud Platform. Private Cloud Controllers function as the brains of the operation, along with ZPA Private Service Edges, to deliver uninterrupted policy-enforced access to private applications, even when the Zscaler cloud is unreachable. Private Cloud Controllers perform the following critical functions:
- Continuously syncs policies and configurations in real time: Any changes made in the ZPA Admin Portal are pushed immediately to Private Cloud Controllers.
- Redirects users for authentication in Business Continuity: Becomes the authentication endpoint for users in Business Continuity, redirects users to the identity provider (IdP), and verifies SAML assertions.
- Redirects users to ZPA Private Service Edges based on load: Maintains the load table of all ZPA Private Service Edges and redirects users closest to the least loaded ZPA Private Service Edges for optimum performance.
- Enrolls new users: Allows new users (never enrolled in ZPA) to authenticate and redirects them to ZPA Private Service Edges.
- Enables App Connectors and Private Service Edges to download configurations: Ensures that App Connectors and ZPA Private Service Edges have the latest policies and configuration.
- Streams logs directly to SIEM: All logs are streamed directly to your SIEM in case of outage detection, ensuring you have visibility into user activity, App Connector status, and ZPA Private Service Edge status in Business Continuity.
Highlights
- Zscaler Private Cloud Controllers: Zscaler Private Cloud Controllers function as the brains of the operation, along with Private Service Edges, to deliver uninterrupted policy-enforced access to private applications, even when the Zscaler cloud is unreachable.
- Zscaler Client Connector: Installed on your users' devices, Zscaler Client Connector connects to the ZPA cloud to enable granular, policy-based access to your organization's internal resources.
- Global Zscaler Cloud: Stitches all components together. The Central Authority (CA) provides a central location for software updates as well as policy and configuration settings. The ZPA Public Service Edges or ZPA Private Service Edges enforce user policies and provide secure transport to the App Connectors.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
