Expanding into new markets is usually a sign that things are going well. For digital banking platforms, however, growth brings a different kind of challenge - more customers, more data, and stricter expectations around availability, security, and regulatory compliance. At Multitude, we operate across 17 countries and deliver digital banking, credit services, payment processing, and regulatory reporting through a platform composed of more than 400 microservices. Each service encapsulates a defined business capability, including onboarding, risk assessment, collections, and compliance workflows. Historically, our services relied on on-premises PostgreSQL and MySQL environments deployed within our own data centers, where capacity scaled vertically on shared compute and storage resources. This model created contention between unrelated workloads and limited their ability to scale independently. Expanding capacity required adding or upgrading physical hardware, which involved demand forecasting, procurement, delivery coordination, and installation within the data center. Over time, continued growth amplified these architectural constraints. The database engines themselves remained reliable, but the surrounding infrastructure limited elasticity and domain-level isolation. As a result, sustained growth began to expose structural limits in the underlying infrastructure. "In a regulated financial environment, those constraints carried broader implications. Frameworks such as DORA and GDPR require predictable availability, controlled recovery procedures, and governed access to sensitive data. As workload demands increased, sustaining both growth and compliance required structural changes at the database layer. We decided that redesigning our data architecture was necessary to improve workload isolation, scalability, and governance alignment. Rearchitecting data boundaries with Azure Databases We initiated our architectural redesign by migrating database workloads to Microsoft Azure and standardizing on Azure Database for PostgreSQL and Azure Database for MySQL for core application services. Central to this redesign was the adoption of bounded contexts. Each bounded context represents a logical business domain and encapsulates the services and schemas required to support that capability. Each domain is owned and managed by a single team, aligning technical boundaries with team responsibility and accountability. Rather than maintaining a small number of large, shared database instances, we provisioned dedicated database instances aligned to defined business domains, establishing domain-level isolation at the database layer. Today, approximately 35 database instances support more than 400 microservices across the platform. Each instance may host multiple schemas serving related services within the same domain, while cross-domain database dependencies are intentionally avoided. This structure limits the blast radius of configuration changes or workload spikes and allows scaling adjustments to be applied within clearly defined domain boundaries. While the bounded context model was a strategic architectural decision, leveraging managed database services helped us implement it by drastically reducing the operational overhead of provisioning, scaling, and maintaining independent instances across domains. Azure Database for PostgreSQL and Azure Database for MySQL provide the managed capabilities required to sustain this model. Instances are provisioned according to the performance and storage requirements of each domain and can be adjusted as workload characteristics evolve. Compute and storage resources are scaled at the instance level, allowing capacity changes to be applied to a specific bounded context without affecting unrelated domains. Altogether, these architectural decisions balance domain-level isolation with operational manageability. A database-per-microservice pattern would significantly increase provisioning, monitoring, and lifecycle overhead without materially improving data ownership boundaries. By grouping related services within bounded contexts, we maintain clear domain alignment while keeping the number of database instances practical to operate. As a result, data boundaries, scaling behavior, and operational controls remain consistent with business domain structures across the platform. Operationalizing high availability and backup strategy To support availability, we deploy Azure Database for PostgreSQL and Azure Database for MySQL with zone-redundant high availability, placing primary and standby replicas in separate availability zones within the same Azure region. Replication preserves transactional consistency, and zone separation reduces exposure to localized infrastructure failures. We periodically exercise failover procedures as part of operational validation to confirm recovery behavior under defined conditions. Availability controls are complemented by a layered backup strategy. Azure Database for PostgreSQL and Azure Database for MySQL provide automated backups with a retention window of up to 35 days and point-in-time restore capabilities. These features allow us to restore a database to a specific timestamp within the retention window, supporting recovery from application-level errors or unintended data modifications without custom snapshot orchestration. Together, operational backups and governed archival retention address both short-term recovery and long-term compliance obligations. Restore operations require documented justification and follow established approval workflows, ensuring that recovery actions remain controlled, traceable, and auditable. We also enforce consistency through lifecycle management. Azure’s managed service model standardizes engine patching and version updates across environments, reducing configuration drift and minimizing manual coordination. By operating within the managed service boundary, the database team can focus on workload analysis, performance tuning, and capacity planning. For migration and synchronization scenarios, we use Azure Data Migration Service to orchestrate controlled cutovers between database environments. Engineers validate configuration and readiness before initiating synchronization, after which Azure-managed replication then maintains data alignment until final switchover. Provisioning decisions and structural modifications remain subject to internal governance approvals to preserve change control and oversight. By combining zone-redundant availability, structured recovery workflows, governed retention policies, and standardized lifecycle management, we operate a database layer engineered for resilience, auditability, and regulatory alignment at scale. Compliance as an architectural property For us, governance is embedded directly into how the platform operates, beginning at the identity layer. Access to Azure Database for PostgreSQL and Azure Database for MySQL integrates with Microsoft Entra ID, aligning database authentication with centrally managed corporate identities. Role-based access control is enforced through enterprise identity policies, providing centralized visibility into access assignments and authentication events across environments. These controls extend into production access management. Privileged access is approval-based and time-bound, and administrative roles are not permanently assigned. Access requests follow defined workflows, and all privileged actions are logged for review under established oversight procedures, ensuring traceability of operational interventions. Database isolation reinforces these identity controls. By aligning database instances with bounded contexts, each business domain maintains a discrete data boundary at the database layer. This structure limits lateral access across domains and confines sensitive data to clearly defined ownership scopes, simplifying monitoring and audit review. In a regulated financial environment, these architectural controls also support compliance requirements under frameworks such as DORA and GDPR. By embedding identity integration, domain isolation, and lifecycle controls directly into the platform architecture, governance becomes an operational property of the system rather than a separate procedural layer. The simplicity of this architecture is a strong driver for both auditability and security of the whole platform. Measurable impact across engineering teams and business outcomes Beyond improved stability, our ability to respond to growth has changed significantly since moving to Azure. In the past, expanding database capacity meant procuring hardware and planning installation in the data center. Now, capacity adjustments happen directly within Azure and can be applied to individual databases instances, allowing us to scale in near real time as workload demands change. Maintenance effort has also decreased. Managed patching, version alignment, and automated backups have reduced the need for manual coordination and reactive capacity management. Infrastructure-level tasks that once required continuous oversight are now handled within the managed service boundary. Our DBAs are now focused on improving performance and stability. We spend far less time maintaining the basics. Resilience by design The structural changes behind these results reflect a deliberate long-term strategy. Our database architecture now aligns with the operating model we expect to sustain over the next five years and beyond. Bounded contexts define discrete data domains, while Azure Database for PostgreSQL and Azure Database for MySQL provide managed high availability, scaling controls, and standardized lifecycle management across those domains. Identity integration and governed recovery procedures operate consistently across environments. With this architecture in place, Multitude scales responsibly in regulated markets while maintaining strict governance and availability standards. Expanding into new markets still means more customers and more data - but now our platform is designed to handle that success.Ignite 2022: Announcing new features in Azure Database for MySQL – Flexible Server
