In the financial sector, the Journey to Cloud is now a driving force that spans the entire IT system. Infrastructure, applications, data, and delivery processes must evolve together to make services more scalable and increase the capacity for change. The choice, therefore, is not just about where to deploy workloads; it concerns the operational model that financial institutions use to design, manage, and ensure the resilience of their digital services.

The transition proceeds at different paces, because priorities depend on the criticality of the processes, integrations with existing infrastructure, and business continuity requirements. The cloud is used in areas where it can support rapid deployment, processing power, and continuous updates; the most sensitive systems often retain on-premises components. This gives rise to the need for a common architectural design capable of enabling different environments to interact without adding costs or complexity.

From Workload to Operating Model

The value of the cloud becomes apparent when migration is part of a modernization roadmap. Moving an application to a new platform without addressing dependencies, integrations, data, and delivery processes leaves the legacy constraints unchanged. The priorities, therefore, become application modularity, release automation, service observability, and consistent management of interfaces between systems.

This evolution requires aligning technological choices with business objectives. The cloud roadmap must clarify which services to modernize, with what levels of control, and based on which performance, continuity, and cost metrics. From this perspective, the cloud becomes a foundation for strengthening existing services and developing new digital, data, and analytics capabilities.

The hybrid requires a common design

The hybrid phase is now a structural reality. Some services are migrating to the cloud more quickly, while highly critical processes and systems remain anchored to on-premises environments. This coexistence addresses concrete needs for traceability, security, integration with legacy platforms, and control over service continuity.

The key focus is managing the interdependence between environments. Cetif evidence shows that when cloud and on-premises environments coexist within the same process, the complexity of integration, monitoring, and orchestration increases. End-to-end governance is therefore necessary: visibility into application dependencies, clear responsibilities, shared integration standards, and recovery procedures that cover the entire service. Without these safeguards, technological stratification can generate new operational costs and slow down evolution.

Front-end and operations: Two Different Rates of Adoption

Adoption is more advanced in access channels. Forty-five percent of institutions are cloud-oriented for their main front-end applications, where scalability and time-to-market directly impact the customer experience and the ability to evolve digital services. Channels can thus benefit more quickly from reusable components, continuous updates, and greater flexibility in managing peaks in demand.

In the “ operations ,” the approach is more cautious: 35% of institutions have adopted a cloud-oriented approach for their primary back-end applications. Integration with core systems, data governance, and security requirements call for more structured migration paths. For these areas, the architectural choice must balance efficiency, resilience, and control, ensuring that local improvements to a single component do not increase the fragility of the entire process.

Potential Impact and Execution Capacity

The experts’ assessment for 2026 confirms a transformation characterized by varying degrees of progress. IT is leading the way, with a high level of readiness and the most substantial investments: the cloud is already a key driver for modernizing infrastructure and applications. Cybersecurity and the “ Advanced Analytics , and AI” have the greatest potential impact, but their readiness still needs to be strengthened; more mature skills, data integration, and security measures are essential for translating this potential into results.

Digital Insurance Claims, Corporate Banking & SME, and ESG Sustainable Finance , on the other hand, maintain a more “follower” position, with gradual adoption and limited investment. The data suggests that the Journey to Cloud is not proceeding uniformly across functions: the priority is to identify, for each domain, the right balance between expected impact, organizational maturity, and governance capabilities.

Resilience and Sourcing Become Part of the Architecture

The Journey to Cloud directly involves security, business continuity, third-party management, and data control. The choice of provider therefore has architectural and risk implications: concentrating a significant portion of workloads with a single provider may simplify the initial rollout, but it increases dependence and reduces options over time.

Multi-cloud and multi-provider models help mitigate the risk of vendor lock-in when supported by a clear strategy. Workload portability, interoperability, data governance, contractual requirements, and exit plans must be defined from the very start of the relationship with vendors. The goal is to ensure that critical decisions remain reversible and to demonstrate the resilience of services, even in the event of disruptions or changes in the scope of sourcing.

Making spending transparent to manage expenses

Cloud governance also includes cost allocation. The pay-as-you-go model makes spending more dynamic and requires the CIO to establish a clear chain of accountability from process to service, from application to function, and to the user. Making this relationship transparent allows for the accurate allocation of usage, the comparison of service value and cost, and the ability to address underutilized or oversized resources.

FinOps brings this discipline into day-to-day management, creating a common language among IT, the “ finance ,” and the business. Control is not limited to verifying actual spending; it extends to architectural decisions, resource sizing, and capacity planning. Technical debt, internal expertise, security, and compliance now weigh less heavily on IT processes than in the past, signaling a greater ability to manage the transformation; however, they remain essential safeguards for consolidating results.

The cloud creates value when it enhances the ability to evolve without losing control over data, dependencies, and costs. For financial institutions, integrating, orchestrating, and governing hybrid environments means transforming migration into a sustainable capability that supports resilience and innovation.
