On June 30, CentOS 7 will reach end of life, requiring migrations in many software stacks and server environments. In advance of this, Zscaler has selected Red Hat Enterprise Linux 9 as the next-generation operating system for Zscaler Private AccessTM(ZPA). RHEL 9 is the modern enterprise equivalent to CentOS 7, backed by Red Hat, and supported through 2032. This continues ZPA's proven stability and resiliency on open source Linux platforms and builds on 10 years of maturity on Red Hat Enterprise Linux-based derivatives. What's more, this transition can be done with no impact to operations or user access.
Pre-built images for all ZPA-supported platforms are targeted for release in May 2024. All ZPA images, including containers, hypervisors, and public cloud offerings, will be replaced with RHEL 9. This is the recommended deployment for all future App Connector and Private Service Edge components, and customers should begin migration immediately on release. For customers that manage their own Red Hat base images, Zscaler is targeting the end of April 2024 for release of RHEL 9-native Red Hat Package Manager (RPM) and repositories.
To ensure an excellent experience for our customers, Zscaler will provide operating system licenses for all RHEL 9 images on supported platforms. This continues our commitment to secure, open source platforms without imposing additional licensing costs on our customers.
We also understand the need for control over security baseline images that meet your security posture and will continue to provide RPM options through support of RHEL 8 and RHEL 9. These software packages are bring-your-own-license (BYOL) and won't conflict with any existing Red Hat enterprise license agreements you may hold.
The CentOS Project and Red Hat will be ending the final extended support for CentOS 7 and RHEL 7 on June 30, 2024. While we aim to provide RHEL 9 support in advance of this date (and do currently support RHEL 8 with RPMs), we recognize that the transition is a large undertaking, affecting all enterprise data centers, and operations and will take time to transition over to new operating systems and software.
In light of this, we want to provide ample time to migrate while considering the security implications of continuing to support an obsolete operating system. Zscaler will support existing CentOS 7 deployments, RPMs, and distribution servers until December 24, 2024. We are confident our ZPA architecture and design uniquely position us to continue to support CentOS 7 past its expiry date. See End-of-Support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.xfor more details on CentOS EOL and the ZPA white paper for architecture and security design.
While we have ample controls in place and the utmost confidence, there is always inherent risk in using an unsupported server operating system. Zscaler will not provide backported operating system patches during this transition, but will maintain the ZPA software and supporting security libraries.
Following Zscaler's cloud-native and best-in-class zero trust approach, ZPA infrastructure components are designed to be lightweight, container ready, and quickly deployed. This allows App Connector and Private Service Edge the benefit of being scaled and migrated without worry for previously deployed instances or operating system upgrade paths. For these reasons, the migration best practice is to deploy new App Connectors and Private Service Edges. Zscaler does not provide direct operating system upgrade paths for currently deployed infrastructure components.
In further support of this, we offer Open Container Initiative (OCI) compatible images for Docker CE, Podman, and Red Hat OpenShift Platform. These images as well as the public cloud marketplaces are fully ready for autoscale groups, supporting quick scale up and scale down.
Zscaler understands your concerns and will fully support you throughout this transition process. Our Technical Account Managers, Support Engineers, and Professional Services are ready to address all concerns related to migration. If a temporary increase of App Connector or PSE limits are needed in your environment to complete migration, there will be no extra licensing costs.
Below are the steps to help you replace CentOS 7 instances with RHEL 9. The enrollment and provisioning of new App Connectors and Private Service Edges can be automated in a few steps using Terraform (infrastructure-as-code) or Container Orchestration to simplify deployment further.
(This version profile can be set as default for the tenant once all connectors are moved to RHEL 9)
