Application Modernization

Today’s modern application is also called a cloud native Application. It is not your “mother’s application” of yesteryear. The modern application attempts to address the failings of the monolithic application that currently IT is burdened with. Monolithic applications are difficult to upgrade and are tightly coupled interdependent applications.— Any change in a version can break the application.

OVERVIEW

How it Works

Modern applications are based on Microservices that are loosely coupled and consistent Application Programing Interfaces (API) The published API for all programs enable programmers to consistently create, manipulate and program applications. The design of applications based on published API’s increase the ease of how infrastructure services are consumed. Databases, Networks, Storage, compute systems when publishing an API lessen the difficulty of access to those services.  

One key element to a Modern Application is the concept of MicroServices. Each Application publishes a set of API’s, that software intermediary allows the programmer to let two applications “talk to each other”. As a whole each application provides microservices that the API specifies how the software components interact with the programming GUI components. There is no single definition of a Microservice, but key elements of this service-oriented-Architecture include: 

  • Loosely coupled services 

  • Fine-grained services 

  • Lightweight protocols 

  • Services in a microservices architecture are independently deployable 

  • Services can be implemented using different programming languages, databases, hardware and software environment, depending on what fits best.

The presence of this ecosystem allows for CI/CD Continuous Integration and Continuous Development methodologies. This avoids the waterfall method of application versioning that monolithic applications are burdened. Changes to applications can be rapidly be deployed and integrated into production and conversely reversed if required. In stark contrasts monolithic applications that require a waterfall deployment have long gaps between versions and each version has immense testing cycles. Bugs are difficult to resolve and are slow to address.

WHY YOU NEED APPLICATION MODERNIZATION

RESPONSE TIME

The monolith application is difficult to maintain over time. It quickly becomes a liability to an organization’s agility to respond to changing business requirements and environment. You cannot re-tool quickly your software and services to meet your customers needs. Moving to a software defined architecture includes addressing the software and applications that utilize this modern SDDC infrastructure. Hardware and software innovations can be quickly put into production and ideas can quickly be brought to market before your competition can react.
