The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.

VMware vSphere Enterprise Plus offers advanced networking and storage features that will support the required high availability, performance, and management capabilities. Features such as Distributed Switches and Network I/O Control (NIOC) are critical to meeting the business-critical application and performance requirements for the latency-sensitive stock trading application.

The solution will deploy a single vSphere Distributed Switch with each host connected to it.

A vSphere Distributed Switch (VDS) is ideal for managing network configurations centrally across multiple hosts, which meets the requirement for centralized vSphere operational management. It also ensures consistent network configurations and simplifies network management at scale.

The solution will configure Network I/O control to ensure that system-level bandwidth does not impact workload network traffic.

Network I/O Control (NIOC) is essential for prioritizing network traffic, ensuring that latency-sensitive workloads are not impacted by other system-level or less critical traffic. This is crucial for the performance requirements of the stock trading application.

vSphere Lifecycle Manager (vLCM) is used to manage ESXi host configurations and software versions in a consistent and streamlined manner. In this case, the architect needs to account for the heterogeneous hardware across two sites (Intel and AMD-based servers).

Since Intel and AMD processors are incompatible for remediation with a single vSphere Lifecycle Manager image, the different processor architectures should be grouped by site (not across sites). Within each site, vLCM can manage a single image per processor architecture, ensuring that each site's hosts with compatible processors are remediated consistently. Intel-based servers will be managed with one image and AMD-based servers with another image, but they can be managed in separate sites.

This approach avoids the issue where heterogeneous hardware with different processor types would need separate images. By keeping them within the same site, the architecture simplifies the lifecycle management and meets the requirement for minimizing clusters and ensuring service availability during upgrades.

vSphere Lifecycle Manager helps reduce operational expenditure (OPEX) by automating the patching and management of the vSphere environment. It provides centralized management for host updates, ensuring consistency across the environment and reducing the manual effort required for ongoing operations. This leads to reduced operational overhead, which directly addresses the requirement to reduce OPEX.

Use an active-active array for Fibre Channel storage-based VMFS datastores

An active-active array provides redundancy and load balancing by allowing multiple paths to be active at the same time, ensuring better performance and fault tolerance. This supports the requirement for redundancy and no single point of failure by ensuring that storage traffic can be distributed across multiple paths to different storage controllers.

Configure a minimum of two paths to every LUN or datastore

Having multiple paths to every LUN or datastore is essential for ensuring redundancy in the storage path. In case one path fails, the system can continue to function by using the other path, meeting the requirement for tolerance to at least one failure.

Configure a minimum of four paths to every LUN or datastore

Configuring four paths further increases redundancy, ensuring that the storage system can tolerate multiple path failures while still maintaining access to the LUN or datastore. This improves load balancing and provides greater fault tolerance.

This solution aligns with the requirements of having a primary and secondary isolated environment, orchestration of application dependencies, the ability to scale on demand in a disaster recovery (DR) scenario, and a single interface for management. VMware Cloud on AWS integrates with VMware's vSphere environment and offers orchestration for DR, as well as the flexibility to scale resources on demand in the event of a DR scenario. It also provides a unified management interface through vCenter.
