Bare Metal vs. Public Cloud: Peak Performance for AI Applications

Paul Painter, Director, Solutions Engineering

The ever-evolving landscape of Artificial Intelligence (AI) demands a robust hosting infrastructure to guarantee peak performance, scalability, and cost-effectiveness. While the public cloud offers undeniable flexibility, bare metal hosting from providers like HorizonIQ provides distinct advantages tailored specifically for the demanding nature of AI applications. 

Let’s delve into the key benefits of hosting AI workloads on bare metal compared to the public cloud.

AI processor

Unparalleled Performance and Low Latency

AI applications, especially those involving deep learning and high-throughput computing, require exceptional responsiveness and minimal delays.  Bare metal hosting offers dedicated hardware resources, bypassing the virtualization layer that can introduce overhead. This translates to:

Superior computational power: Dedicated resources ensure faster processing and reduced inference times.

Enhanced model training efficiency: Eliminate bottlenecks for faster model development and training cycles.

Improved overall application performance: Critical for real-time AI applications like autonomous vehicles, financial trading algorithms, large language models (LLMs), and healthcare diagnostics.

Tailored Infrastructure for Demanding Workloads

Bare metal hosting offers unparalleled control and customization over the hardware and software stack.  AI developers can fine-tune the infrastructure to their specific models’ needs, optimizing resource utilization for accelerated compute tasks. This level of control is particularly beneficial for:

Complex AI workloads: Fine-tune hardware configurations for specialized needs.

Low-level optimizations: Unrestricted access empowers researchers and data scientists to push the boundaries of innovation.

Prioritizing Data Privacy and Security

Data privacy and security are paramount for AI applications handling sensitive information. Bare metal hosting allows organizations to:

Maintain complete control over data: Minimize the risk of exposure or unauthorized access inherent in multi-tenant public cloud environments.

Ensure regulatory compliance: Meet industry standards and instill confidence regarding data integrity and confidentiality.

Cost-Efficiency for Predictable Workloads

While the public cloud offers scalability and pay-as-you-go models, bare metal hosting can be more cost-effective in specific scenarios. Here’s why:

Eliminate virtualization overhead: Reduce costs associated with hypervisor licensing, instance sizing, and resource contention.

Predictable pricing: Flat, predictable pricing from HorizonIQ avoids variable costs associated with public cloud usage.

Optimized cost-performance ratio: Organizations with consistent or high-performance workloads benefit from long-term cost savings.

Navigating Compliance and Regulatory Requirements

Certain industries face stringent data privacy, sovereignty, access, and auditing regulations. Bare metal hosting offers greater flexibility in adhering to these mandates, making it an attractive option for AI applications in highly regulated sectors like finance, healthcare, and government.

Choosing the Right Infrastructure for AI Success

While the public cloud offers convenience, bare metal provides distinct advantages for performance-critical AI workloads. By carefully evaluating factors like data privacy, regulatory compliance, and workload demands, organizations can make informed decisions about the hosting solution that aligns best with their AI objectives, leading to success in the era of AI-powered innovation.

Choosing a Public Cloud: Avoiding Noisy Neighbors

Paul Painter, Director, Solutions Engineering

I frequently hear people asking how to choose from among so many potential cloud options. The answer, I’m afraid, is “It depends.” Some cloud providers may over-provision their resources, causing your traffic to slow down. This drop in service is often called the “noisy neighbor” syndrome, but how can you avoid this?

Location, Location, Location

Just like choosing a house, it’s important to get a comfort level with the neighborhood. To evaluate cloud provider environments, you need to ask a few questions:

1.) What is the underlying hardware in the cloud environment?

For performance issues, you first want to confirm that the processor is equal or greater in horsepower than your computing needs. It is also important to know if hyper-threading is activated on the processor. For example, our AgileCLOUD is built using Intel e5-2650v3 processors, which have 10 cores running at 3.0 GHz per core and hyper-threading enabled, effectively doubling the processing power.

2.) What is the vCPU ratio?

In a virtual cloud environment, the hypervisor will divide the CPU cores into smaller mini-CPUs or virtual CPUs (vCPUs). Many providers will oversubscribe the available vCPUs; in other words, they will assign more vCPUs than physically available. This assumes that running virtual servers requires all the CPU cycles assigned. Cloud environments that oversubscribe are often cheaper and are ideal for workloads that are typically idle most of the time.

When a guest operating system is installed on the hypervisor, the guest instance is assigned a pool of vCPUs, as well as virtual RAM (vRAM) and disk storage to be used. The hypervisor manages the time a vCPU has access to the physical CPU in a round-robin manner, thus creating vCPU queues.

3.) What are the underlying disk configuration and network speeds?

The local disk type (SSD or HDD), number of disks and the RAID configuration will affect the performance of an I/O intensive application. AgileCLOUD uses SSD disks with RAID10, providing the fastest local disk performance possible.

Hypervisors and the Noisy Neighbor Syndrome

Just like large lots make for quiet neighborhoods, a low physical to virtual ratio makes for good computing. A cloud with a low ratio will have more access to the physical hardware, like a house with a large yard keeps noisy neighbors’ music from disturbing your dinner. A higher ratio of resources means you have less access to the actual physical hardware, which would be like your townhouse neighbor’s rock band practicing next door.

Understanding a cloud provider’s performance is more complicated than vCPU price performance.

  • Compare the processor speeds: some cloud providers have different generations on hardware with different clock speeds (and cores).
  • What is the oversubscription ration?
  • Available Disk I/O, both read/write capacity of the drive and network access if attaching to a block storage device are critical to server performance.
  • Finally, understand the physical network capacity of the server to move both LAN/WAN data and any storage access.

INAP Provides You Options

Our AgileCLOUD for example, comes in two flavors and, depending on your workload, one may be better than the other. Our Series A is specifically suited for web, application and light I/O workloads. Our Series B is better suited for applications that have higher CPU and memory demands.

Answering which of these two options is better for you depends on the workload you have, and the answer may even be both!  Let me break down the differences for you. The obvious differentiator between the two options is the hypervisor on the AgileCLOUD lineup.

To keep it simple, our AgileCLOUD offers two series of cloud compute (see table below).

Our A Series, good for small databases, websites and content management systems that require moderate CPU utilization has a 3:1 vCPU to CPU ratio.

Our B Series, better for medium databases, complex websites and scheduled batch processing tasks requiring heavy memory and CPU utilization has a one to one (1:1) ratio.

In other words, we don’t overprovision on the B series, so there is no chance of CPU contention and little chance of that noisy neighbor.

Armed with this knowledge, we believe that you will be in a better position to understand the vast array of available cloud options.
