A customer requests a review of its current vSphere platform design.
The following information is noted:
There are three different workload profiles for the virtual machines:
Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.
Tier-3 virtual machines operate platform management tools such as vCenter Server and have different lifecycle management requirements.
Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.
The Chief Information Security Officer (CISO) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards.
The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server.
The Operations lead has stated that management changes have consistently been rejected by application teams.
As a result of the review, which recommendation should the architect make regarding the design of this platform?
