The Financial Services Sector’s GenAI Surge in a Container Driven World

The financial services industry is no stranger to IT transformation, and is in the midst of a significant one, rapidly adopting Generative AI (GenAI) and embracing widespread application containerization. 

The 7th Annual Nutanix Enterprise Cloud Index Report for Financial Services paints a compelling picture: a sector eager to leverage these innovations for productivity, efficiency, and automation, yet grappling with critical challenges in infrastructure, security, and skills.

Containerization Is Fueling the Future—but Adding Complexity

Every financial services respondent (100%) is containerizing applications, with 98% citing the benefits of cloud-native applications and containers. This trend is hardly surprising, given the agile and scalable environment containers can provide - essential for handling sensitive financial data across hybrid and multicloud setups.

The container surge is especially pronounced for GenAI workloads —outpacing even dev/test workloads. Containers offer the modular and scalable environments GenAI requires, particularly when integrating with legacy systems.

However, this widespread adoption isn't without hurdles. A significant majority of financial services are managing multiple Kubernetes® environments, complicating infrastructure modernization, container-native application development, data silos, and application portability. The underlying message - while containers are the engine of modern financial applications, the infrastructure supporting them needs significant upgrades.

GenAI Ambition Is Soaring, But Infrastructure Lags Behind

The vast majority of respondents are already leveraging GenAI, particularly in customer support and content generation. Yet this is only the beginning. Over the next 1–3 years, priorities are shifting toward mission-critical areas like cybersecurity, fraud detection, and code generation - reflecting a maturation in how GenAI is being applied.

Despite this enthusiasm, GenAI expansion raises serious concerns. Data privacy and security top the list, as the biggest challenges to scaling GenAI. Nearly all respondents (97%) believe they could be doing more to secure GenAI models and applications. AI control and guardrails are paramount in the industry and respondents signal a need for stronger data governance frameworks and security-oriented infrastructure modernization.

Skills and Infrastructure Gaps Are Holding Back GenAI Scale

A staggering number of financial services respondents face challenges scaling GenAI from pilot to production. The biggest issues? A lack of skills and friction with existing infrastructure. While 65% believe they currently have the necessary skills, 62% are actively hiring to close the gap. This tension reflects the competitiveness that organizations should expect to find in hiring and retaining IT talent able to help meet organizational objectives for GenAI implementation.

GenAI’s success will depend not just on recruitment, but also on continuous upskilling of existing teams. Alongside talent development, modernizing IT infrastructure is essential. Ninety-two percent say their current infrastructure needs improvement to meet data security requirements - especially in hybrid multicloud environments where consistency and compliance can be difficult to maintain across platforms.

The Long Game: ROI Expectations and Strategic Commitments

Short-term GenAI ROI may be mixed, 39% expect losses in the next year, but the long-term view is more optimistic, with 58% anticipating gains within 1-3 years. This reflects a willingness to invest in GenAI over time, with the understanding that iterative improvements and strategic alignment are necessary for meaningful returns.

Still, many firms report difficulty measuring ROI. Clearer metrics, tied to both IT performance and business outcomes, will be critical as organizations seek to justify continued investment.

The Bottom Line

The financial services industry is not short on ambition when it comes to GenAI as early adoption is widespread, and plans are aggressive. But momentum will fade without parallel investment in infrastructure, skills, and security.

Containers and multicloud strategies are emerging as enablers of this GenAI push, yet they add layers of operational complexity that can’t be ignored. The challenge now is to connect innovative intent with foundational readiness.

GenAI may be the spark, but modern infrastructure and skilled teams are the fuel. The institutions that master both will lead the next wave of transformation in financial services.
