The Advantages of AVS: Reducing Host Overallocation Through Supply Chain Elimination

by Greg Kaffenberger

Azure VMware Solution (AVS) is a powerful software-defined datacenter seamlessly integrated into Microsoft Azure Cloud. It provides users with the flexibility to purchase resources on an hourly basis or through one- or three-year reserved instances, offering various host sizes to accommodate diverse resource needs. In this article, we’ll delve into how AVS can reduce your reliance on hosts by removing traditional supply chain constraints.

Right Buying is Right Sizing

The central theme of Azure VMware Solution is its ability to optimize resources, resulting in tangible cost reductions. Let’s explore this in the context of AVS’s approach to resource allocation and how it relates to the absence of supply chain constraints.

Breaking Free from Supply Chain Limitations

Unlike traditional on-premises datacenters, which often require extensive capacity planning and substantial upfront investments, AVS offers remarkable flexibility. In the cloud environment, resources are acquired on-demand, eliminating the need to predict future capacity requirements or make significant initial investments.

Shedding On-Premises Supply Chain Constraints

Let’s take a closer look at the typical constraints encountered in traditional on-premises environments:

  • Free Space for New Projects: On-premises datacenters must predict needs for future projects, which can lead to unnecessary over-provisioning.

  • Discount Dilemmas: To secure the best discounts, organizations often find themselves forecasting future capacity needs and purchasing resources prematurely.

  • Upgrades with Minimal Disruption: Space must be reserved for equipment upgrades without causing operational disruptions.

  • Equipment Failures: Adequate space must be set aside for the prompt replacement of failed equipment.

  • Accommodating Organic Growth: Additional space must be allocated to accommodate natural growth in data and workloads.

These constraints often result in data centers being over-provisioned, especially during the initial stages of equipment ownership due to supply chain limitations. However, Azure VMware Solution operates on a more flexible principle.

Unleashing Cloud Freedom

In the cloud landscape, these constraints no longer apply. Organizations leveraging AVS can acquire resources based solely on real-time virtual machine utilization. During migration and ongoing operations, hosts can be added as needed, eliminating the guesswork and over-provisioning that are common in conventional datacenters.

Data-Informed Decision-Making

By analyzing utilization data from existing virtual machines, organizations can accurately estimate their host requirements. This allows for the adoption of versatile reservation strategies, including rapid migration with on-demand resources or prudent estimation of host needs with the purchase of reserved instances upfront.

The Benefits of Supply Chain Elimination

By freeing themselves from supply chain constraints, organizations significantly reduce their dependence on additional hosts to ensure fault tolerance, allocate free space for upgrades, and accommodate organic growth. In a scenario where a failed node can be replaced in just 15 minutes, the need for extra nodes to support compute fault tolerance becomes almost unnecessary. AVS’s use of VMware VSAN as the primary storage solution has its own fault tolerance requirements. Ensure you take all software constraints into account when designing fault tolerance. 

Enhancing Cost Efficiency

The key takeaway here is that the elimination of supply chain constraints can substantially reduce the number of hosts required, resulting in significant cost savings. Azure VMware Solution encompasses various factors contributing to a diminished total cost of ownership, enhancing its appeal in terms of resource efficiency.

In conclusion, Azure VMware Solution not only offers a seamless cloud-integrated datacenter solution but also revolutionizes resource allocation by removing supply chain constraints. It is essential, however, to consult with experts in cloud technology to effectively evaluate and compare your options. Embracing AVS not only ensures cost-efficiency but also unlocks scalability and agility, revolutionizing how organizations manage their IT infrastructure while reducing their reliance on hosts.
