Keyhole Consultants are currently leading an initiative at a large financial services firm to move a large, monolithic, legacy application running in the organization’s “on-premise” data center, to a microservice-based suite of applications running in the “cloud.” The application is being iteratively moved to containers, orchestrated by Kubernetes in the AWS Cloud.

The effort was centered on developing a more agile environment including process, practices, and technology choices, with the goal of cultivating a DevOps culture.

M204 To Spring Boot Microservices

In this project, almost 1,000 existing Model 204 batch applications were converted to Java Spring and Spring Batch-based applications.

The goal of this engagement was for Keyhole Software to help the client to implement an application architecture and platform that supports the conversion of its Model 204 applications into Spring Boot-based application modules. There were many modules, both batch and online-based, so this platform needed to allow for scalability and durability. On-demand deployment was also necessary.

Modernization: HTML5 Designer Tool

A team of Keyhole Consultants has been focused on a rewrite initiative for a client proprietary Designer tool.

This tool enables a non-programmer to create a form-based web application by dragging UI elements onto a page of a form. The form contains pages that have UI elements. Each element has a number of associated properties, interactive at design-time. Each element can have behaviors that impart program logic to the form. The form can have a workflow associated with it. The tool user interacts with those artifacts by dragging and dropping elements, drawing behavior or workflow connections, modifying properties, and then saving the form, as XML, to a server. A web-based player interprets the form XML to serve it to an end-user as a web application.
