Project Snapshot

Leading a client team to cloud-hybrid microservices with OpenShift

Keyhole re-architected a large, monolithic, legacy application to a microservice-based suite of applications running in the cloud.

Technologies: Java, Microservices Architecture, Kubernetes, OpenShift, Spring Boot, AWS Cloud, React, Cypress, DevOps, Spring/Netflix OSS

The Java application was iteratively moved to containers, orchestrated by Kubernetes in the AWS Cloud. Additionally, the team introduced a React SPA-style UI and architected DevOps automation for hybrid cloud using OpenShift.

The success of this project led to the creation of a DevOps team and an enterprise-wide automation platform, supporting dozens of development teams across many disciplines.

Typical Modernization Approach

Though every project is a custom engagement, we have a generalized path for taking our clients through successful modernization. We help companies at every step, whether you are just now looking into modernization options, or are in the middle of your modernization efforts and need sharp implementers.

Analysis & Assessment

We analyze current application architecture, tooling, and environments. This can include interviews with members of your technical team to highlight architectural constraints, current practices, and blockers.

Keyhole will produce a document with identified findings, including a summary of suggestive approaches that can deliver the most value to the organization.


Strategic Modernization Planning

Using the Assessment document, Keyhole Software works with your team to help estimate and establish an incremental modernization plan to fit within established budgets.

Whether the best path is a rewrite to modern technologies (like SPA, Java or .NET), code transformation, migration from proprietary solutions to open source or cloud, or another approach, our consultants work with your team directly to plan successfully.

Educational Component

Current development personnel must be educated to be successful with new approaches.

Educational services include lab/lecture courses, informal hands-on exercises, and mentoring.

Popular Courses

We teach every technology we work in.
