    Cloud Migration and Modernization Services

    Bluelupin plans and runs cloud migration projects. We assess each application, set up a secure cloud foundation, move workloads and databases in planned waves with rollback steps, and rebuild the parts that benefit from containers or serverless. We work mainly on AWS and also on Azure. After go-live, our cloud operations team can run it.

    Move or rebuild: how we choose for each application

    There are four ways to take an application to the cloud. We pick one for each application, based on how it is built, how often it changes and what it costs to run today.

    Rehost

    Move the application as it is to cloud servers. It is the fastest option with the least change, and suits stable applications that work well today.

    Re-platform

    Move with small changes, such as a managed database in place of a self-run one, or the application packaged in containers, so it is easier to run.

    Refactor or rebuild

    Redesign the application as cloud-native when it must scale or change often. It takes longer and leaves the most room to grow.

    Retire or replace

    Switch off what nobody uses, or replace it with a ready-made product when one already does the job.

    The assessment decides the option for each application separately.

    Assessment and migration plan

    As a cloud migration company in India working with teams in India and abroad, we start every cloud transformation with an assessment, so you see the plan and its risks before anything moves.

    1. Inventory

      A list of your applications, databases and servers, and how they depend on each other.

    2. Priority

      Which applications matter most to the business, and which can move first with the least risk.

    3. Cost and risk

      The cost of running each application today against its cost in the cloud (TCO), and the risks of each move.

    4. Wave plan

      Applications grouped into migration waves, each with a cutover window and rollback steps.

    The output is a wave plan for you to review and approve, with the chosen option and the rollback steps for every application.

    Landing zone and security baseline

    A cloud landing zone is a pre-set cloud environment with security, networking, identity and governance rules in place. We set it up before any workload moves, so every application lands on the same secure foundation. On AWS we build it with AWS Control Tower.

    • Separate accounts for production, testing and shared services
    • Network design (VPC) with private subnets and controlled access
    • Identity and access by role
    • Encryption for data at rest and in transit
    • Central logging and audit trails
    • Guardrails that block settings your policies do not allow

    Moving workloads and databases

    Workloads move in planned waves. Each wave has a cutover window agreed with your team, checks before and after the switch, and a rollback step if something does not work as expected.

    AWS migration

    We move servers and applications to AWS wave by wave. Each cutover is rehearsed first, runs in a planned window and has a tested way back to the old setup.

    Database migration

    Data is copied by replication, such as AWS DMS and read replicas, while the old database keeps running. We check that the data matches, then switch over in phases within a short planned window.

    Cloud-native modernization

    Cloud-native development means building or rebuilding an application to use what the cloud does well: scaling on demand, managed services and automated setup. We use it for the parts of your systems that must scale or change often.

    Serverless and containers

    Lambda, ECS, Fargate and Kubernetes, with blue-green deploys, so a new version runs beside the old one and traffic switches when it is ready.

    Managed data and messaging

    Aurora, DynamoDB, SQS and EventBridge, with caching, so you run fewer database and queue servers yourself.

    Infrastructure as code

    Terraform and CloudFormation, so every environment is set up the same way, with drift detection that warns when a setting is changed by hand.

    Breaking up a monolith

    We split a large application step by step with the strangler-fig approach, moving one part at a time into its own service. For older systems, see Legacy Application Modernization.

    For web and mobile products we build on AWS with API Gateway, Lambda, ECS, S3, CloudFront, Cognito and managed databases, designed to scale automatically.

    Resilience and disaster recovery

    We design each system to keep running when a part of it fails. That means deployments across more than one availability zone (multi-AZ), health checks that replace a failing server, backups and failover options, with runbooks matched to your recovery time and recovery point targets (RTO and RPO).

    Keeping cost in check during the move

    Cost is part of the migration plan. We right-size each workload before it moves, so you do not pay for capacity it never used. Every resource is tagged by product and environment, and budgets with alerts show a jump in spend within days instead of at month end.

    After migration

    At go-live we hand over the runbooks, the architecture notes and the access, so your team can run the new setup. If you want us to support the applications after the move, see Application Support and Maintenance.

    How long it takes: A focused module usually takes 8 to 12 weeks, and a larger program 4 to 9 months in phased releases.

    Cloud migration FAQs

    Common questions about cloud migration.

    Do you work on AWS only, or on other clouds too?

    We work mainly on AWS, and also on Microsoft Azure when your systems or policies need it.

    What is a cloud landing zone?

    A landing zone is a pre-set cloud environment with security, networking, identity and governance rules in place. It is the foundation every migrated workload moves into.

    Can you migrate databases with minimal downtime?

    Yes. We use replication, such as AWS DMS and read replicas, and a phased cutover, so the switch happens in a short planned window.

    Can you move a monolith to cloud-native?

    Yes. We break it up step by step with the strangler-fig approach, move parts into containers or serverless, and extract services one at a time instead of rewriting everything at once.

    What about disaster recovery?

    We design backups, failover options and runbooks to match your recovery time and recovery point targets.
