Modernization to the Cloud


Modernized Code, Cloud-Ready


TSRI's near-100% automation process transforms legacy applications to cloud-native application in AWS, Azure, OpenStack, BlueMix, DISA, or other cloud architectures. 

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 30 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 Migration
to the Cloud

We have 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

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

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

Native-Cloud, Docker, Kubernetes and Containers, Lambda/API Gateway

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

Cloud Case Studies

TSRI has completed over 250+ major past projects including modernizations targeting private and public cloud architectures. We have achieved success on every past project with references available.


TSRI Advantages

Scalability & Interoperability

TSRI can help bring legacy systems into highly scalable, flexible cloud platforms.

Eliminate Unnecessary License Fees

Remove costly, proprietary runtime annual license fees by transforming to "license-fee free" Java, C++, or C# code. TSRI's transformed code carries no costly proprietary runtime fees.

Eliminate the Mainframe

Move off mainframe systems and reduce operational and maintenance (O&M) expenses. Reduce your hardware failure risk and footprint and move to high performance computing systems.

Retarget Existing Databases

While modernizing the application logic, TSRI offers customers the options of retaining the existing database or moving your database to a new target, including SQL Server, Oracle, or open source databases.

Transform Languages Simultaneously

TSRI's toolset and process allows for the simultaneous modeling and automated transformation of other languages commonly present in legacy systems.

Go from Monoliths to Microservices

With additional refactoring, TSRI can break monolithic systems into microservices. Many of these refactorings can be automated, reducing time and effort.

Reuse & Iterative Approach

Reuse of modernization and refactoring rules allows for a faster portfolio-wide modernization of your applications. These great efficiencies and reuse means less time to market, minimal business disruption due to our iterative approach, and larger economies of scale/lower modernization costs.

Eliminate Dead & Redundant Code

TSRI's model-based toolset allows for fully automated remediation of dead and redundant code, as well as the consolidation of similar statements and methods to improve maintainability. Because this process operates on the model level, functional equivalence is preserved during all refactoring.

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 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, also known as lift and shift, moves but does not modernize an application. The application remains in its legacy language without any change to behavior, code, database, or UI.

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

The solution retains the legacy language, so development and maintenance continue to be difficult, human resources are often scarce and quite costly, and the customer may be exposed to increased technical debt as fewer and fewer resources are available. The significant licensing costs associated with rehosting can also be unattractive.

Rehosting is a great temporary solution to leave a 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, then later transformed their application with TSRI.

A full rewrite means green fielding or reengineering an application from the ground up.

It is the most time consuming and expensive option for modernization and migration. Full rewrites require securing a team of engineers, PMs, and other resources. Additionally, you will need a thorough understanding of how to build the application to be cloud-native.

While it's possible to see long-term benefits, the high-risk, high-cost, and extremely long cycle—oftentimes measured in years—to release typically doesn’t achieve the desired value in most scenarios.

If your application and its functionality need to change dramatically (30%-plus change in functionality) then a full rewrite makes sense.

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

While it makes sense to modernize your applications and get away from legacy environments such as mainframes and thick-client applications due to the functionality, security, and human-resource availability, 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.
