Banco Bradesco partnered with Microsoft to migrate legacy workloads to Azure, adopt Power Platform for citizen development, and modernize its customer‑experience stack. The move cut infrastructure spend by 22 %, reduced time‑to‑market for new services from months to weeks, and positioned the bank for a multi‑cloud future.

What Changed

In May 2026 Banco Bradesco announced the completion of a three‑year transformation that moved more than 70 % of its core banking workloads from on‑premises data‑centers to Microsoft Azure. The migration was coupled with a rollout of the Power Platform (Power Apps, Power Automate, Power BI) across business units, enabling non‑technical staff to build and iterate on internal tools. The initiative also introduced Azure Arc to extend Azure governance to the bank’s remaining private‑cloud nodes, and Azure OpenAI Service to pilot AI‑driven fraud detection.

The partnership was highlighted on the Microsoft Partner Community Hub, where the bank shared its migration timeline, cost‑benefit analysis, and lessons learned. The case study underscores how a large financial institution can combine IaaS, low‑code development, and AI services to meet regulatory demands while staying agile.

Provider Comparison

Aspect	Microsoft Azure (Banco Bradesco)	Amazon Web Services (Typical Alternative)	Google Cloud (Typical Alternative)
Core Compute	Azure VMs with Confidential Computing for PCI‑DSS workloads; Spot VMs used for batch processing, achieving ~30 % cost savings.	EC2 with Nitro Enclaves; comparable pricing but higher egress fees for inter‑region traffic.	Compute Engine with Confidential VMs; lower base price but limited regional availability in Latin America.
Hybrid Management	Azure Arc extends Azure Policy and Sentinel to on‑prem servers, giving a single pane of glass for compliance.	AWS Outposts provides hardware‑based extension but requires separate licensing and management plane.	Anthos offers hybrid control but adds complexity and a separate subscription model.
Low‑Code Platform	Power Platform integrates natively with Azure AD, Dynamics 365, and Microsoft 365; licensing bundled with existing Microsoft 365 Enterprise agreements.	AWS Honeycode is still in preview and lacks deep integration with SAP or Oracle workloads common in banking.	AppSheet integrates with Google Workspace but requires separate data‑loss‑prevention policies for regulated data.
AI Services	Azure OpenAI Service (ChatGPT, embeddings) available within a government‑grade network, simplifying compliance audits.	Bedrock is powerful but data residency for Brazil requires additional VPC peering and legal review.	Vertex AI offers strong ML pipelines but does not yet provide a managed ChatGPT‑style service inside a sovereign cloud.
Pricing Model	Pay‑as‑you‑go with Enterprise Agreement discounts; Azure Reserved Instances combined with Savings Plans reduced compute spend by 22 % for Bradesco.	Savings Plans similar but higher baseline rates; egress charges can increase total cost of ownership.	Sustained‑use discounts are automatic, but lack of long‑term reservation options for certain VM families can raise costs for steady workloads.
Migration Tools	Azure Migrate, Database Migration Service, and Cloud Adoption Framework provided a prescriptive path; partner ecosystem (e.g., Accenture, Infosys) offered certified accelerators.	AWS Migration Hub and Server Migration Service are mature but require more manual scripting for database schema conversion.	Migrate for Compute Engine is solid for lift‑and‑shift but less integrated with on‑prem Oracle environments common in banks.

Key Takeaway: For a Brazilian bank with heavy regulatory constraints, Azure’s integrated identity, compliance, and low‑code stack delivered a smoother end‑to‑end experience than the alternatives, especially when the bank already held a Microsoft 365 Enterprise agreement.

Business Impact

Cost Reduction – By consolidating compute on Azure Spot VMs and leveraging Reserved Instances, Bradesco reported a 22 % reduction in infrastructure spend over three years. The Power Platform licences were covered under the existing Microsoft 365 agreement, avoiding separate SaaS fees.
Speed to Market – Citizen‑development teams built over 150 internal applications (e.g., loan‑approval dashboards, compliance checklists) in weeks rather than months. Power Automate cut manual workflow handling time by 40 %.
Regulatory Alignment – Azure Policy and Microsoft Sentinel provided continuous compliance monitoring for PCI‑DSS, LGPD, and Basel III requirements. Audit reports could be generated automatically, trimming audit preparation cycles from 6 weeks to 2 weeks.
Talent Enablement – The low‑code approach reduced reliance on scarce Java/.NET developers for internal tooling, allowing senior engineers to focus on core banking APIs and innovation projects.
Future‑Proofing – With Azure Arc and the OpenAI Service in place, Bradesco now has a clear path to integrate AI‑driven fraud detection and personalized product recommendations without building separate data‑science pipelines.

Migration Considerations for Other Enterprises

Assessment Phase – Use the Azure Cloud Adoption Framework to inventory workloads, classify data residency requirements, and calculate TCO. Bradesco’s initial assessment identified 45 % of workloads as “cloud‑ready” and 30 % as “re‑architect”.
Pilot First – Start with a non‑critical workload (e.g., a reporting database) to validate networking, identity federation, and cost‑management tags.
Hybrid Governance – Deploy Azure Arc early to bring policy enforcement to legacy VMs; this avoids a hard cut‑over and eases audit compliance.
Skill Development – Invest in Power Platform training for business analysts; Microsoft offers free Power Platform Learning Paths that reduce onboarding time.
Vendor Lock‑in Mitigation – Leverage Azure Arc and open‑source tools (e.g., Terraform) to keep infrastructure as code portable across clouds.

Strategic Recommendation

For organizations that already consume Microsoft 365 and Dynamics 365, extending into Azure and the Power Platform yields immediate operational efficiencies and a unified security model. The Banco Bradesco case demonstrates that a disciplined, phased migration—backed by Azure’s hybrid tools and low‑code services—can deliver measurable cost savings while unlocking the agility needed for next‑generation banking experiences.
