IaaS Stability Woes: Fighting the Losing Performance Battle Against Unfair Resource Provisioning

  1. iaas-performance

When the performance isn’t stable on your IaaS VM and you can barely scale resources to accommodate demand spikes, know that you could have fallen prey to unfair resource provisioning by your cloud vendor.

Before reaching out to vendor support requesting small tweaks that address the issue momentarily, it’s important to understand why you’re facing the issue in the first place. Most IaaS providers are not running clustered, high availability architectures. Vendors often deploy your VM on a stand-alone server that is also occupied by a number of noisy neighbors battling for the limited resources of that same server. Vendors are incentivized to maximize the number of VMs they deploy on each server, thereby increasing returns on investments while also compromising your ability to scale resources at the rapid pace of your business growth. As a result, you will rarely have much overhead on any server, which prevents you from resizing the server to squeeze more resources. The only real solution to increasing resource capacity is to migrate the workload to new servers because the existing server resources are already sold to other users.

Business organizations want to understand their capacity and limits to scale IT resources in context of varying business demands. The solution for cloud vendors is to promise accurate and predictable performance, stability and scalability figures. However, vendors will rarely present accurate information if their cost-cutting and profitability maximization efforts potentially lead to unfair resource provisioning.

HOSTING understands these customer pain points and offers transparent and customer-centric resource provisioning services to maximize stability and performance for end-users. HOSTING’s highly available public and private clouds leverage fully-clustered high availability architectures – our cloud platforms are continually rebalancing workloads across the entire site to ensure that everyone is able to leverage the resources they’re paying for. HOSTING provides the most predictable and constant level of performance to your VMs – especially notable against the massively spikey AWS storage offering. Some providers can achieve slightly higher raw performance as customers are accessing local disk instead of a SAN, but this capability is never advantageous when performance is neither guaranteed nor predictably available. For applications that demand predictable performance, the most advantageous solution for your organization is the HOSTING unified cloud — a multi-cloud high-availability cloud architecture developed on a hybrid network and transparently connected to assets running on other platforms such as AWS and Azure. To learn more, download Leveraging the Unified Cloud for Business Transformation white paper.
