We migrate your organization enterprise applications to AWS or Azure with detailed migration plans, cloud-native architectures that make the most of each platform capabilities, and a methodology that guarantees business continuity throughout the process. We reduce infrastructure costs, improve availability and prepare your technology stack to scale with artificial intelligence.
Enterprise Application Migration to AWS and Azure
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 result is a modern cloud infrastructure, more resilient, easier to operate and significantly more cost-effective than the on-premise infrastructure it replaces.
We start with a complete inventory of your organization'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 migration plan and the 7R classification of each workload.
We define the target cloud architecture for each group of 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 versus the current on-premise infrastructure.
We configure the base cloud environment — 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 in ordered waves by criticality: we start with the lowest-impact applications to validate the methodology, identify and resolve the issues that always arise in the first migrations, and build team confidence before tackling the most critical business applications.
Before each cutover, we run comprehensive tests in the cloud environment: load tests to validate behavior under expected peak demand, security tests to validate the implemented controls, and disaster recovery drills to validate that DR procedures work within the target time objectives.
We execute the final cutover 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.
On-premise infrastructures have high fixed costs — hardware, licenses, electricity, cooling, physical space, operations staff — regardless of actual usage. The cloud allows paying only for what you use, scaling elastically according to demand and leveraging economies of scale that no company can replicate individually.
AWS and Azure offer availability SLAs greater than 99.99% in their managed services, with automatic replication between availability zones and geographic regions that guarantee business continuity even in the face of serious infrastructure failures. We implement multi-AZ architectures and disaster recovery strategies that meet the most demanding RTO and RPO requirements.
We analyze the complete portfolio of your organization's applications and classify each one according to the most appropriate migration strategy: Rehost (lift & shift), Replatform (lift, tinker & shift), Refactor (re-architect), Repurchase (SaaS), Retire (decommission) or Retain (keep on-premise temporarily). This classification defines the migration plan, timelines and budget for each workload.
We migrate your 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, SNS or S3 for the various architecture components.
For organizations 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 components.
Migration is the ideal opportunity to modernize applications while moving them to the cloud. We use the process to containerize applications still running on bare-metal servers, migrate databases to managed services that eliminate operational burden, implement autoscaling that didn't exist on-premise and adopt cloud-native patterns that improve resilience.
The cloud can be more expensive than on-premise if not managed correctly. 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, auto-scaling policies and cost monitoring dashboards per service and team.
We design and implement cloud security architecture: 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 the regulatory standards applicable to your sector — ISO 27001, ENS, PCI-DSS, HIPAA.
