Quickly Modernize Your Mainframe
Technology for AWS

Migrate to the cloud faster with TSRI's reusable process and scalable solution


Seamlessly Migrate Valuable Mainframe Technology with TSRI's AWS-Certified Engineers and Architects

As an AWS Mainframe Migration Competency Launch & Certified Technology Partner, TSRI's certified engineers and architects get mainframe software into the cloud quickly leveraging our automated refactoring technology.
Our near-100% automation process transforms legacy applications to Cloud-native applications directly for deployment on AWS.

Our model-based solution transforms even very large (tens of millions of lines of code) legacy systems written in languages like COBOL, Fortran, PowerBuilder, Ada, MUMPS, VB6, and more than 35 other languages, into modern applications in cloud native target architectures. The output is a multi-tier application, taking advantage of cloud utilities and scalability.

TSRI's Migration to AWS Cloud

TSRI has extensive experience in all forms of legacy code transformation, including migration to cloud services and containerization. TSRI can move the currently-modernized applications to the cloud using cloud-specific refactorings – targeting services, micro-services, and containerization. Our migration services take a three-step approach:


Migrate monolithic applications to service-oriented applications

Migration of legacy monolithic code to a service-oriented environment. This includes updating language from COBOL to Java or C#, changing databases, and refactoring to enable microservices. This step begins the process of abstracting underlying services from the application.

Migrate service-oriented to native-cloud services

Integration of service-oriented applications with native cloud services. This could include re-orienting code from, for example, WebSphere DB2 legacy platforms to Apache Tomcat and Amazon RDS. Upgrading to incorporate the latest native architectural interfaces ensures that applications are tightly integrated with the new environment, and ensures easier updates in future.

Native-cloud, docker, kubernetes and containers, lambda/API gateway - serverless framework

Transformation of native cloud to Docker Containers. The movement to containers provides additional architectural abstraction and improved integration of applications within the cloud.

AWS Cloud Case Studies

For over 25 years, TSRI has focused on modernizing the world's most critical technology. From retail and financial systems to mission-critical military applications, TSRI has completed over 250+ projects including modernizations targeting private and public cloud architectures. We are pleased to bring our experience to AWS cloud migrations, and have achieved success on every past project with references available.


Choose Your Path to
the Cloud

The key to a successful migration is to evaluate and model the underlying legacy code logic and to pinpoint those areas which must be adapted to the new environment. Not every application has a natural and hazard-free path to a cloud-based, containerized solution. 

Multiple Approaches to the Cloud:

In software transformation, changes are made to deliver a new system that has the same functionality of the legacy system, but it is "transformed" to meet the goals of a specific project like cloud migration. TSRI's fully-automated toolset ingests each software application and transforms it into a modern, native, object-oriented target language.

Transformation, coupled with Refactoring is the right choice for you, if you want a functional equivalent cloud-native application that will be maintained and actively developed on in the future.

The TSRI modernization approach includes refactoring and optimization of the modernized software systems. In performing this function, we can evaluate source code and model it, refactoring it into microservices that permit a flexible and modern approach to integration with cloud services.

TSRI's experience in over 250 legacy application transformations for major software systems includes innumerable success stories of re-architecture in moving older systems of a wide variety of languages and structures to modern, architectures.

Rehosting and Lift & Shift, is moving but not modernizing the application, remaining in the legacy language without any change to it's behavior, code, database or UI.

Rehosting is a great solution if the application is not actively maintained, will be sunset or decommission in two to three years, and only needs to move off its current hardware or platform.

The solution retains the legacy language, and so development/maintenance continues to be difficult, resources scarce and quite costly, and exposes the customer to increased technical debt as fewer and fewer resources are available. The significant license costs associated with rehosting can be unattractive.

Rehosting is a great temporary solution to get off the legacy environment and achieve savings quickly, which in turn can be used to transform or refactor the application. In fact, some of our clients have rehosted and then transformed their application with TSRI!

A full rewrite, is green-fielding or reengineering an application from the ground up.

It is the most time consuming and expensive option for modernization and migration. It requires securing a team of engineers, PM's and other resources. Additionally, you’ll need a thorough understanding of how to build the application to be cloud-native.

While it's possilbe to see long-term benefits, the high-risk, high-cost, and extremely long cycle to release is typically not worth it in most scenarios.

If your application and its functionality needs to change dramatically (30+% change in functionality) then then a full rewrite makes great sense.

Yes, you are reading this right! You can indeed do nothing and push out your modernization journey until a later point.

While we want you to modernize your applications and help you get away from legacy environments, such as mainframes and thick-client applications - we understand that sometimes the timing is not right...yet.

Even in this case we can still support you in the final modernization planning and provide legacy code-level documentation via our Application Blueprint® ("As-Is") documentation for over 35+ different legacy languages to support and lower the cost of your O&M maintenance costs.
