Cloud Application Modernization

Cloud Application Modernization

Transform your legacy applications to make them Cloud-ready and take a full advantage of what Cloud has to offer in terms of agility, scalability, and performance.

Transform your legacy applications to run in Cloud 

Very often organizations feel pressure to move to the Cloud without fully understanding the level of their readiness to operate in a new infrastructure paradigm. It’s true that during migration from the traditional data-center approach to the Cloud, applications need to be tuned up for the new environment and requirements like security and scaling should be taken into account. Such changes need a specific competency which is not often present within traditional development teams. Sometimes it’s due to limited experience with Cloud architectures and frameworks, or lacking the best practices in combining Cloud-native features with traditional container-based on VM-based applications. But a reliable Cloud software development partner can fill this gap.

Cloud offers numerous possibilities in terms of agility, scalability, and performance. But to fully leverage its immense potential and keeping the cost efficiency, oftentimes application modernization services are required first.

Legacy application modernization strategy

Consider new software development paradigms, frameworks, and architectures:  

  • Microservices
  • Containerization
  • Serverless computing
  • Infrastructure as a Code
  • Multi-tenancy
  • Security enablement
  • Cloud-native services

Why Cloud modernization

To manage cost efficiency within continuously changing market environments, businesses need to maintain their agility. It enables you to link your costs to actual service usage, on one hand, and gives an ability to deliver features and fixes extremely fast on another. That’s why application modernization is only one step on your Cloud journey, but a very important one. To be better aligned with the new Cloud environment, you need to customize your applications. Here’s why you need to refactor your application with the following assumptions:

  • Avoid Monolithic, tightly coupled application
  • Dependency on physical resources
  • Avoid stateful programming, stateless is the key for fast scaling
  • Increase scalability and performance
  • Eliminate high cost of licensing, e.g. move from Oracle to AWS RDS Postgres
  • Enhance end-user experience, it could be a good time to refresh your UI/UX
  • Adoption to DevOps best practices with using CI/CD for smooth release and upgrade

Application modernization with Cloud migration

We offer the proven application modernization roadmap that includes the following:

  • Reimagine the user experience in ways that are consumer-centred & market-relevant.  
  • Evaluate application Cloud-readiness and design Cloud architecture to support Cloud modernization.
  • Build out new or optimize existing Cloud infrastructure as foundation for transformation.
  • Transform your application for optimal Cloud operation using an agile, minimum viable product (MVP) approach.  

As a result, get enhanced user experience; secure, scalable and automated Cloud environment with the frameworks and tools that will help you accelerate innovation; modernized application, refactored using Cloud-native architectures and services; and a roadmap for continued modernization to achieve long-term business goals.   

  • Assess infrastructure architecture and optimize Cloud architecture design to support modernization requirements.   
  • Study the current app test and deploy procedure to ensure a proper support handoff or modification of existing app functionality, if needed.  
  • Perform additional assessments according to business needs: Security, Cloud Economics, DevOps, Cloud Operations.  

App migration assessment takes into consideration a broader context, legacy, and limitations. During this stage an optimal strategy will be decided, ensuring data consistency and no app downtime in the migration process. To avoid getting users blocked or lose their productivity with the app, migration experience of the end user is mapped. And finally, security and data access plan is developed for the process

  • Gain a higher degree of comfort with Cloud or emerging technologies and validate technical decisions.
  • Quickly demonstrate to stakeholders, investors, and consumers end-to-end functionality and prove value in a cost-effective manner.
  • Create the foundational infrastructure and technical components for an MVP build.

This stage is all about determining the scope and success criteria for PoC, designing and building out minimum Cloud infrastructure to support it. Use experience design techniques to prototype user interaction, leverage an agile approach to build PoC, and hold regular meeting to review progress and discuss changes.

  • Translate modernization requirements and assessment results into high-level epics and User Stories to be decomposed into backlog during MVP sprints.  
  • Prioritize User Stories and define the MVP to accelerate time to value.  
  • Define a phased plan to serve as a roadmap to how business value can be realized.   
  • Define resource plan, on-/offshore locations, and costs to deliver.  

Review business goals and modernization drivers and develop high-level Epics/User Stories based on modernization requirements and assessment results. Work with key stakeholders to understand critical business goals, select Epics/User Stories to include in the MVP based on these goals. And then prioritize the remaining User Stories for high-level roadmap and phased implementation plan.   

Cloud Build-out  

  • Build-out or modify existing Cloud infrastructure as defined by architecture assessment. 
  • Follow best practice patterns, such as common shared services for logging, monitoring and security.  
  • Create frameworks and tools needed by development teams to accelerate innovation and facilitate agile processes.
  • Leverage CTP’s minimum viable Cloud (MVC) methodology and infrastructure automation framework.   


  • Establish CI/CD processes and tool chain, including automated testing and code promotion, to speed development cycles.  
  • Design, develop, and test MVP features using a cost-effective delivery model and a lean/agile approach to drive time to market.  
  • Validate designs throughout the development Lifecycle to ensure engaging user experiences. 
  • Continue to optimize infrastructure and maintain Infrastructure as Code. 
  • Maintain CI/CD scripting and automated testing throughout the development lifecycle.  

At this stage expect to perform Agile/Scrum training, if needed, as well as Sprint planning and refinement. Other activities involve: developing Experience Design artifacts, completing DevOps tooling, designing and coding features in sprint backlog, developing automated unit tests and including in DevOps tool chain, developing and executing functional tests, refining Cloud infrastructure as needed. 

Why Cloud migration

Migrating to the Cloud will help you achieve multiple business results, such as:  

  • Faster time-to-market of the new features in your app.  
  • Improved cost efficiency and flexibility for your business solutions.   
  • Increased rate of innovation, as instead of managing and maintaining the data bases, you may focus on customer value generation.   
  • More reliable application with easier scalability, performance and modern app development practices integrated.
