Enterprise Application Migration to AWS and Azure in Madrid
At MiT Software we specialize in migrating enterprise applications from on-premise infrastructures and legacy cloud environments to AWS and Azure. Our migration methodology is based on the AWS 7R framework — Rehost, Replatform, Refactor, Repurchase, Retire, Retain, Relocate — and adapts to the specific characteristics of each application to maximize cloud benefits while minimizing migration risk and time. We have experience migrating all types of workloads: web applications and APIs, relational and NoSQL databases, batch processing systems, desktop applications transitioning to web, and complete microservices architectures.
The application portfolio inventory of a large Madrid organization is often a revealing process: forgotten applications still running, hidden dependencies between systems and applications that are candidates for decommissioning. We conduct this inventory rigorously, documenting each application, its dependencies and its criticality, as the basis for a well-prioritized cloud migration plan.
Designing the target cloud architecture for a large Madrid organization involves strategic decisions that go beyond technology: cloud account and organization model, connectivity strategy with on-premise systems, security and governance model, DR strategy and cost model. We design a cloud architecture that balances all these factors to maximize the value of the investment.
The landing zone is the foundation on which all the Madrid organization's cloud infrastructure will be built. We configure this base environment with the highest standards of security, governance and operability: multi-level account structure, segmented private networks, identity and access policies, security and compliance tools, and centralized observability mechanisms.
For large Madrid organizations with extensive portfolios, the wave migration methodology is the only way to manage the complexity and risk of a large-scale cloud migration. We design the wave plan with careful prioritization that balances progressive learning, risk minimization and visible business value generation in the early phases.
Cloud migrations of critical systems for Madrid organizations require an exhaustive validation process before any cutover. We run complete test suites — load, security, integration and DR — adapted to each system's requirements, with clear acceptance criteria that determine whether the system is ready to receive production traffic.
The cutover of critical systems at large Madrid organizations requires maximum preparation and coordination. We plan each cutover with the level of detail of a business continuity plan: maintenance window agreed with all stakeholders, tested rollback plan, 24h incident response team available and reinforced monitoring during the stabilization period.
Large Madrid organizations maintaining their own data centers or significant on-premise infrastructure incur high fixed costs that are not justified in the cloud era. Migration to AWS or Azure transforms those fixed costs into an optimized variable model, with the possibility of reducing infrastructure spending by up to 35% in the first years after migration.
Large Madrid corporations in regulated sectors — banking, insurance, telecommunications — need to guarantee the availability of their critical systems with very demanding SLAs. AWS and Azure offer the availability levels, geographic resilience and disaster recovery capabilities needed to comply with regulatory requirements and the expectations of the most demanding customers.
Madrid organizations with extensive application portfolios need a rigorous assessment and planning process before starting any cloud migration. We apply the AWS 7R framework to classify each application according to the most appropriate strategy, and build a detailed migration plan that balances business value, technical risk and team capacity.
For Madrid organizations choosing AWS as their primary cloud platform, we design the most appropriate target architecture for each workload type and execute the migration with our proven methodology: complete inventory, detailed design, validated incremental migration and post-migration optimization that maximizes the value of the AWS investment.
Large Madrid organizations in the Microsoft ecosystem get especially high returns when migrating to Azure. We leverage Microsoft ecosystem synergies to design an Azure architecture that maximizes the value of the organization's existing technology investments — Enterprise Agreement licenses, Active Directory, Microsoft 365 — in the new cloud infrastructure.
The cloud migration of a large Madrid organization is a unique opportunity to modernize the technology portfolio without incurring separate and costly modernization projects. We identify which applications benefit from containerization, migration to managed services or refactoring to adopt cloud-native patterns during the migration process, maximizing the value of the initiative.
Large Madrid organizations with hundreds of cloud services and multiple development teams need mature FinOps discipline to keep cloud spending under control. We implement a cloud spending governance model that includes complete visibility by team and project, continuous optimization processes and a culture of financial accountability in engineering teams.
Madrid organizations in regulated sectors must ensure their cloud infrastructure complies with ENS, GDPR, PCI-DSS or any other applicable regulation. We design a cloud security architecture that meets all relevant regulatory requirements while maintaining the operational agility that justifies cloud adoption.
