Enterprise Application Migration to AWS and Azure in Barcelona
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.
We start with a complete inventory of your Barcelona company's application portfolio: dependencies between systems, traffic volumes, business criticality, technical state of each application and availability and security requirements. This inventory is the basis of the cloud migration plan and the classification of each workload according to the 7R strategy.
We define the target cloud architecture for each group of your Barcelona company's applications: which cloud services to use, how to design the virtual network, how to manage identities and access, how to implement business continuity and how to structure the cost model to maximize savings compared to the current on-premise infrastructure.
We configure the base cloud environment for your Barcelona company — accounts, organizations, virtual networks, DNS, IAM, centralized logging, monitoring and security tools — following AWS or Azure best practices to ensure all migrated workloads land on a secure, governed and production-ready base infrastructure.
We execute the migration of your Barcelona company's applications in waves ordered by criticality: we start with the lowest-impact applications to validate the methodology and resolve the issues that inevitably arise in the first migrations, building team confidence before tackling the most business-critical applications.
Before each cutover in cloud migration projects for Barcelona companies, we run comprehensive tests: load tests to validate behavior under expected peak demand, security tests to verify the implemented controls and disaster recovery drills to validate that DR procedures work within the defined target time objectives.
We execute the final cutover of Barcelona companies' systems with minimum maintenance window and intensive monitoring during the first 48 hours. After confirming cloud environment stability, we initiate the controlled decommissioning of the on-premise infrastructure and perform an optimization review that identifies additional cost reduction and performance improvement opportunities.
Barcelona companies with on-premise infrastructure bear high fixed costs regardless of actual usage. The cloud allows paying only for what is consumed, scaling according to business demand and leveraging economies of scale that no company can replicate individually. Migration to AWS or Azure is one of the highest-return investments for growing Barcelona companies.
AWS and Azure offer availability SLAs greater than 99.99% in their managed services, with automatic replication between availability zones that guarantees operational continuity even in the face of serious failures. For Barcelona companies with high availability requirements, we implement multi-zone architectures and disaster recovery strategies that meet the most demanding RTO and RPO.
We analyze the complete application portfolio of your Barcelona company and classify each one according to the most appropriate migration strategy: Rehost, Replatform, Refactor, Repurchase, Retire or Retain. This classification defines the migration plan, timelines and budget for each workload, guaranteeing a realistic roadmap prioritized by value.
We migrate Barcelona companies' applications to the most appropriate AWS services for each workload: EC2 for applications requiring full server control, ECS or EKS for containerized applications, RDS or Aurora for relational databases, Lambda for serverless functions, and managed services like ElastiCache, SQS or S3 for the various architecture components.
For Barcelona companies in the Microsoft ecosystem, we migrate to the equivalent Azure services: App Service for web applications, AKS for Kubernetes, Azure SQL Database for relational databases, Azure Functions for serverless computing, and managed services like Azure Cache for Redis, Service Bus or Blob Storage for the various architecture components.
Cloud migration is the ideal opportunity to modernize your Barcelona company's applications. We use the process to containerize applications still running on bare-metal servers, migrate databases to managed services that eliminate operational burden, implement autoscaling and adopt cloud-native patterns that improve system resilience.
The cloud can be more expensive than on-premise if not managed correctly. For Barcelona companies, we implement FinOps practices that guarantee cloud spend control: right-sizing of instances, use of Reserved Instances or Savings Plans for predictable workloads, Spot Instances for interruption-tolerant workloads and cost monitoring dashboards per service and team.
We design and implement cloud security architecture for Barcelona companies: least-privilege IAM identity and access model, encryption at rest and in transit for all sensitive data, virtual private networks with trust-level segmentation, and compliance controls aligned with GDPR and the regulatory standards applicable to each sector.
