A new version of Omnissa Horizon has just been released, and 2603 is not just another update — it’s an ESB (Extended Service Branch) release and marks an important transition point for many environments.

🔗 Release Notes:
https://docs.omnissa.com/bundle/horizon8-rnV2603/page/Horizon8-ReleaseNotes.html

First things first: end of support for vSphere 7

Let’s start with something critical:

Horizon 2603 ESB no longer supports vSphere 7.x

• Horizon 2512 was the last release supporting vSphere 7
• Starting from 2603, vSphere 8 is the required platform

This means one thing:
If you’re planning to move to this ESB, your vSphere upgrade is no longer optional — it’s mandatory

This is a key architectural checkpoint, especially for environments that have been delaying the jump to vSphere 8. (vSphere 7 is end of support)

Event Database + Integrated Authentication (finally!)

Now, let’s talk about one of my favorite new features.

Horizon 2603 introduces the ability to configure the Event Database on Microsoft SQL Server using Active Directory identities (Domain User with Integrated Authentication).

No more SQL authentication.

Why this matters:

• Eliminates stored SQL credentials
• Aligns with enterprise security best practices
• Simplifies credential lifecycle management
• Improves compliance and auditability

From a design perspective, this is a very welcome step toward a more secure-by-default architecture.

 Final thoughts

This release is not just about new features — it’s about setting a new baseline:

• ✔️ ESB = long-term stability
• ✔️ vSphere 8 as the standard
• ✔️ Stronger security integration

If you were waiting for the “right moment” to modernize your Horizon platform… this is probably it.

 In the next posts, I’ll dive deeper into the other new features and changes introduced in Horizon 2603 — stay tuned 👀
