JtmCode: Building Modern Enterprise Applications: Inspired by the Mainframe Legacy

Developing complex enterprise applications can be a daunting task. The traditional approach requires a "full-stack" developer mastering various technologies, making them a scarce resource. Additionally, the complexities of frameworks like Vue.js, Angular.js, or React can add further challenges.

However, the enduring success of mainframe systems offers valuable lessons. Their secret lies in a core component: the middleware. This software layer sits between the operating system and application code, acting as a communication hub. It ensures reliable exchange of data between users, applications, and external systems. The middleware efficiently manages user sessions, handling input, context data, and output presentation.

Drawing inspiration from this robust and centralized approach, we can redefine how we build modern enterprise applications. This new approach will:

• Reduce development complexity by simplifying the application building process.
• Decrease reliance on scarce "full-stack" developers by enabling a more modular development approach.
• improve code maintainability and reusability through well-defined and centralized communication mechanisms.
• Enhance overall development efficiency streamlining workflows and leveraging specialized skills.

By learning from the past, we can build modern enterprise applications that are robust, scalable, easier to manage, and tailored to meet the specific needs of complex business environments.

By prioritizing simplicity throughout business application development, we ensure your modern application, like its mainframe predecessors, is built to endure for years to come.

Modern Enterprise App Development: Move In, Not Build the House

Imagine building a new life, but instead of laying the foundation, framing the walls, and installing plumbing, you want to move in and start enjoying it. That's the philosophy behind our approach to modern enterprise applications.

Our foundational system software is akin to a pre-built, reliable house. We leverage the proven and enduring principles of mainframe architecture, ensuring its stability and longevity for decades to come.

This eliminates the need for you to spend time and resources on low-level development like writing core code and managing infrastructure. Instead, you can focus on what truly matters: building your business.

Think of it like this:

• Traditional approach: Like building a house from scratch, you'd need a team of specialists for various tasks – foundation, framing, plumbing, etc. This is time-consuming and requires extensive expertise.
• JtmCode approach: We provide the finished house, ready for you to move in. You just need a carpenter (Java programmer) to customize the interiors and add your personal touches - the functionalities specific to your business.

This streamlined approach offers several advantages:

• Faster development: Get your application up and running quickly, focusing on core business logic.
• Reduced costs: Eliminate the need for extensive upfront investment in infrastructure and low-level development.
• Simpler maintenance: Benefit from a robust and well-maintained foundation, minimizing ongoing maintenance hassles.

JtmCode empowers you to move in and start building your business, not wasting time laying the foundation.

OS Isolation from different versions	add_circle_outline Docker containers can isolate any system software upgrades;    I.E. an OS upgrade to the host system will require regression testing, maybe code changes / recompiles; BUT by using Docker containers, the application program runs in its own version of the OS, which is part of the container and is therefore unaffected		Not possible	Not possible
New for 2021 February, Single Sign On (SSO)	add_circle_outline Allow user Logon Authenication using Open Id Connect (OIDC) standard. Farm out Logon to third party ie. Auth0 which handles all password authenication or 2FA or password recovery.   With the additonal benefit of hacking detection and handling of 'Denial of service' (DOS) attacks. Once Authenicated, OIDC allows mulitple browser tabs to go directly to their first screen without logon again.		Not possible	Not possible
