Cost Considerations in Gen AI Deployment: Cloud vs On-Premises

October 11, 2024 By: Debabrata Debnath

According to McKinsey’s 2024 Global Survey, 65% of organizations worldwide are regularly using Gen AI to enhance their performance. That is double the percentage from their previous survey just 10 months ago, in 2023.

Generative AI could significantly boost productivity, potentially adding $2.6 trillion to $4.4 trillion annually to the global economy. The rapid growth of this technology is mainly due to its improved natural language understanding, crucial for tasks that can automate 60-70% of current business operations.

Its ability to generate novel insights from existing data has made it integral across industries, from R&D to customer operations. However, a key dilemma rattles businesses when they think of Gen AI deployment: whether to opt for an on-premises model or a cloud solution. This decision is heavily influenced by cost considerations.

The expenses involved can vary significantly depending on the deployment model chosen. These include initial setup, maintenance, scaling, and ongoing operational costs. This blog will explore a cost comparison between on-premises and cloud deployment models to aid in this decision-making process.

Cost Benefit Analysis: Cloud v/s On-Premises Gen AI Infrastructure

When deciding between cloud and on-premises infrastructure for Gen AI deployment, several factors come into play. Cloud solutions offer flexibility and scalability, allowing businesses to scale resources up or down based on demand without large upfront investments. Conversely, on-premises infrastructure provides greater control and security, critical for sensitive data and compliance-heavy industries.

Following is a list of charges businesses accrue over time for both these models.

Initial Investment: If an on-premises infrastructure is chosen for Gen AI deployment, businesses would inevitably incur hefty upfront expenses. This is because setting up a physical data center is a costly endeavor. businesses need to bear the initial hardware expenses. They also need to invest in cooling systems, power supplies, and network infrastructure.

With cloud-based solutions, however, upfront costs are much lower. This is due to the fact that businesses don’t need to create or maintain the virtual ecosystem. It is already supplied by a third-party vendor. On top of that, businesses only need to shift to a pay-as-you-go model, which can be cost-effective for variable workloads.

Operational Expenses and Scalability: On-premises deployments offer greater control over data and infrastructure but can be challenging to scale quickly and efficiently. Businesses need to invest in hiring experts to manage the infrastructure, along with maintenance charges and upgrades of both hardware and software within their data centers.

Cloud-based generative AI models significantly reduce operational expenses by leveraging cloud infrastructure’s scalability and cost-efficiency. They provide unparalleled scalability, allowing businesses to quickly scale resources up or down based on demand. This flexibility is ideal for Gen AI applications that require varying computational resources.

Open Source Language Models: Using open-source Large Language Models (LLMs) on-premises can be more cost-effective. These models, especially those with fewer parameters, can handle many business tasks without needing extensive infrastructure. On-premises deployment can reduce infrastructure costs since it uses existing resources within the organization. Data remains within the organization’s network, enhancing security.

It’s not always true that cloud deployment is cheaper. Using cloud services for AI can sometimes be more expensive due to the cost of API calls. These costs can add up, especially with high usage and large context windows. Cloud costs can vary significantly depending on the load and usage patterns, sometimes making it a less economical choice compared to on-premises solutions.

Data Security and Compliance: Running Gen AI solutions on on-premise models offers distinct advantages over cloud platforms. This is mainly because data is stored in enterprise servers rather than in vendor servers. So, organizations retain a lot of control over proprietary intelligence and don’t have to stress about third-party infiltration.

They also aren’t restricted to generalized security standards for their defenses. Their in-house security team can customize security protocols according to company needs.

However, if businesses don’t have a dedicated IT team monitoring risks, they would become vulnerable to data breaches or malware attacks. Additionally, they might run the risk of being non-compliant.

In this context, cloud-based platforms like Generative AI on Google Cloud have the upper hand. While businesses may not always know the exact location of their data, they’re assured that an expert team is continuously tracking threats.

ROI and TCO: On-premises Gen AI models involve high initial capital expenditures (CapEx) and ongoing operational expenses for maintaining physical infrastructure. businesses with consistent Gen AI usage can achieve significant ROI by customizing data centers to their needs. However, those with fluctuating Gen AI demand may struggle with resource underutilization, impacting ROI.

In contrast, Generative AI in a cloud allows businesses to scale resources as needed and pay only for what they use. This reduces overall costs and lowers CapEx compared to on-premises setups. While cloud deployments minimize financial waste, recurring contract renewals can accumulate costs over time, necessitating long-term financial planning.

As Gen AI continues to evolve, several key trends and innovations are shaping its deployment, particularly focusing on solutions and advancements in cloud technology.

Since both of the above-mentioned approaches come with their pros and cons, businesses today are often seen opting for a hybrid solution that combines on-premises and cloud-based infrastructure. This approach allows leveraging the strengths of both environments, balancing data privacy, and performance needs.

This model enables businesses to retain the flexibility and cost-effectiveness of the cloud while being able to uphold the security perks of on-site infrastructures.

A convenient middle ground can thus put an end to this debate as businesses go on augmenting operations with Gen AI and cloud services.
