Rehosting (Lift & Shift)
This is the fastest path to the cloud. We migrate your existing application architecture to a modern cloud infrastructure with minimal code changes. It's the ideal first step for organizations looking to quickly exit data centers, reduce infrastructure costs, and gain foundational cloud benefits like scalability and reliability.
- Rapidly migrate applications to IaaS platforms like AWS EC2 or Azure VMs.
- Achieve immediate cost savings on hardware and data center maintenance.
- Establish a cloud footprint as a foundation for future optimization projects.
Replatforming (Lift & Reshape)
Replatforming involves making targeted cloud optimizations during migration without changing the core application architecture. This could mean moving from self-managed databases to managed services like Amazon RDS or Azure SQL, or containerizing parts of the application. This approach provides a better price/performance ratio and unlocks more cloud capabilities than a simple rehost.
- Leverage managed cloud services (PaaS) to reduce operational overhead.
- Improve application performance and scalability with minimal refactoring.
- Implement containerization with Docker and Kubernetes for portability and efficiency.
Cloud-Native Development
For applications that require maximum agility and scalability, we help you refactor or rebuild them using cloud-native principles. This involves breaking down monolithic applications into microservices, leveraging serverless functions, and building CI/CD pipelines for rapid, automated deployments. This is the path to true digital transformation.

From High-Cost Legacy to High-Agility Cloud
"The modernization project was a game-changer. We've gone from deploying updates quarterly to weekly, and our infrastructure costs are down 40%. Developers.dev was not just a vendor; they were a true transformation partner."
The Problem
The bank's monolithic COBOL-based system was a major bottleneck. Every minor change required months of testing, API integrations were nearly impossible, and the escalating licensing and hardware costs were unsustainable.
Key Challenges
- Migrating decades of sensitive financial data with zero data loss.
- Ensuring compliance with strict financial regulations (PCI DSS, SOX).
- Minimizing downtime during the transition to avoid disrupting banking operations.
- Retraining the internal IT team on new cloud technologies.
Our Solution
We executed a phased replatforming strategy to a secure AWS environment.
- Conducted an AI-powered assessment to map all system dependencies and data flows.
- Containerized the application components using Docker and orchestrated them with Amazon EKS (Kubernetes).
- Migrated the mainframe database to Amazon Aurora PostgreSQL for improved performance and scalability.
- Built a robust DevSecOps pipeline with automated compliance checks and security scanning.
Modernizing Retail for the On-Demand Economy
"Black Friday used to be a nightmare of server crashes. After Developers.dev refactored our platform to microservices on Azure, we handled 5x our previous peak traffic without a single issue. Our conversion rates have never been better."
The Problem
The tightly-coupled nature of their monolithic application meant that a failure in one module (e.g., inventory) could bring down the entire site. Deploying a simple bug fix was a high-risk, all-or-nothing event.
Key Challenges
- Decomposing the monolith into logical microservices without disrupting sales.
- Ensuring data consistency across distributed services.
- Implementing a robust API gateway for secure service communication.
- Managing a complex, multi-service production environment.
Our Solution
We refactored the monolithic application into a collection of independent microservices hosted on Microsoft Azure.
- Used Domain-Driven Design to identify service boundaries (e.g., Product Catalog, Cart, Orders, Payments).
- Developed services using .NET Core and deployed them as Azure Functions and App Services.
- Implemented Azure API Management as a secure gateway for all internal and external API calls.
- Established comprehensive monitoring and observability using Azure Monitor and Application Insights.
Unlocking Trapped Value from Mainframe Data
"Our mainframe data was a black box. Developers.dev helped us rehost it to Google Cloud, making it accessible to our data science team for the first time. The insights we've gained have already optimized our routes, saving us millions."
The Problem
The high MIPS (Million Instructions Per Second) costs of running queries on the mainframe made data analysis prohibitively expensive. The business couldn't get the real-time insights needed to compete in a fast-moving logistics market.
Key Challenges
- Extracting and converting data from proprietary EBCDIC format to ASCII.
- Ensuring data integrity and synchronization during the migration process.
- Replicating complex batch processing jobs in a cloud environment.
- Building a secure and performant data access layer for analysts.
Our Solution
We executed a rehosting strategy to move the mainframe data and processing to Google Cloud Platform (GCP).
- Used specialized tools to extract, transform, and load (ETL) mainframe data into BigQuery.
- Re-engineered COBOL and JCL batch jobs into modern Python scripts running on Cloud Composer (Airflow).
- Built secure REST APIs using Cloud Endpoints to provide real-time data access to other applications.
- Empowered the analytics team with Google Data Studio and Looker for powerful, self-service reporting.

Frequently Asked Questions
Rehosting (or "Lift and Shift") is like moving your application from an on-premise server to a cloud server (IaaS) with almost no changes. It's fast and simple. Replatforming (or "Lift and Reshape") is a step further; you move the application but also make some optimizations to leverage cloud services, like switching from a self-managed database to a managed cloud database (PaaS). Replatforming offers more cloud benefits for a modest increase in effort.
Security is our top priority. We use a multi-layered approach: 1) All data is encrypted in transit and at rest using industry-standard protocols. 2) We establish secure, private connections (like VPN or Direct Connect) between your environment and the cloud. 3) Access is strictly controlled using IAM (Identity and Access Management) policies with the principle of least privilege. 4) We conduct thorough security audits before, during, and after migration.
The timeline varies significantly based on the application's complexity, the chosen strategy, and the amount of data. A simple Rehosting of a single application might take 4-8 weeks. A more complex Replatforming project could take 3-6 months. A full Refactoring of a large monolith into microservices can be an ongoing program over 12+ months. Our initial 'Discover & Assess' phase provides a detailed and realistic timeline for your specific project.
Our goal is always to minimize or eliminate downtime. For critical applications, we use strategies like blue-green deployments, where we set up a new, identical environment in the cloud. We test it thoroughly, and then seamlessly switch traffic from the old environment to the new one. For data migration, we use continuous replication tools to keep the old and new databases in sync, allowing for a near-instantaneous cutover with minimal service interruption.
We calculate ROI by looking at both "hard" and "soft" savings. Hard savings are direct cost reductions, such as eliminating data center hardware, maintenance contracts, and software licensing fees. Soft savings are business value gains, which include increased developer productivity (faster time-to-market), improved application performance and reliability (better customer experience, higher conversion rates), enhanced security (reduced risk of breaches), and the ability to innovate and launch new features that were previously impossible.
