The key pillars of legacy migration and digital transformation

Many organizations may find migrating legacy applications to be a daunting or unneeded task. However, failing to update can impede business growth and impede agility. Those who have successfully shifted from a monolithic architecture to a modern cloud-based composable microservices architecture have experienced numerous advantages.

Here is a summary of the changes in technology during the last few years and how modernization and best practices differ.

Event-Driven Architecture

Event-Driven Architecture (EDA) may not be as well-known as cloud or DevOps, but it is essential for a microservices-oriented architecture. Unlike request/response-driven legacy architectures, EDA allows for real-time, asynchronous interactions with software.

With EDA, events are sent without waiting for a response and can be consumed by receiving applications as needed, which fits perfectly with the loosely coupled components of microservices. In short, Event Driven Architecture is essential for modern software architecture.

It enables components to be created, implemented, deployed, and managed independently, with the capacity for modifications and scalability.

DevOps Pipelines for Rapid, Reliable Software Delivery

DevOps and the cloud are closely related. Developing on the cloud makes it easier to transition from development to deployment. Many leading cloud platforms offer continuous integration, delivery, and infrastructure automation to enable DevOps. Strong DevOps (or DevSecOps) practices and implementations are crucial for the quality and speed of modern application development.

Finding the right balance between releasing new features and guaranteeing reliability for users is critical. With more operational systems, SRE (Site Reliability Engineering) can be used to automate tasks and troubleshoot.

Containers and Microservices

Containers have been a significant force in software development over the past decade, driving DevOps processes with their modularity and looser coupling. It has enabled microservices to become the predominant architectural pattern, breaking applications into individual, self-contained services in place of giant, complex monoliths.

This shift has had far-reaching implications for how businesses operate, enabling them to focus more on product management, features, and optimizations - tasks that are difficult in legacy systems.

Automation and Infrastructure-as-Code (IaC)

Migrating to an event-based microservices architecture may bring about some complexity, but it can also diminish it in other areas. Infrastructure automation is the answer to this, as it allows the entire architecture and infrastructure to be coded, developed, changed, and automated – freeing it from the restrictions of legacy/monolithic applications.

A vital advantage of this is the ability to quickly create and remove test environments as needed, along with the relevant application, in a cloud environment.

API Integrations

APIs are at the core of this current system infrastructure/architecture method, which provides a universal way to supply and access services from a growing ecosystem. Utilizing APIs grants the capability to link and combine services and data inside an organization and facilitates broader integration with external systems and data sources.

Employing APIs can fuel your products and services by controlling services and gaining access to more comprehensive data, eventually providing more value to customers or to you internally.

Eight Key Steps for Successful Modernization

Legacy migration services are essential for businesses transitioning from outdated systems to more efficient, modern, and scalable solutions. Here are eight key considerations for engaging in legacy migration services

Distinct types of migration

There are two distinct types of migration: lift-and-shift and business transformation:
  • 01

    Lift-and-shift

    Lift-and-shift is transferring an outdated system initiated by the IT department. It usually occurs when engineers determine that the current software could be more convenient and impede the business's smooth operation.
  • 02

    Business transformation

    On the other hand, business transformation is a response to an inefficient software platform that impacts the business's functioning. For example, suppose a rapidly growing company uses a monolithic architecture that can no longer scale. In that case, it may switch to microservices to gain more flexibility and capacity for expanding operations.
