Why Companies Use Outdated Legacy Systems?

Many businesses still use outdated systems. This is due to many factors, which we will describe below.
Business Requirements
Investment 360
Coping with Challenges
Business Requirements

  • Many existing legacy applications were designed and custom-built to fulfill the main business requirements and perform functions, following specific processes of the organization. So even if the system is outdated, it still performs its functions, and the business continues to use it.

  • All processes are tied to an outdated solution, and its reworking will be a significant step, as it will be necessary to globally switch to newer processes.

  • Employees have been using applications for many years, know their specifics and dependencies. Replacement of the outdated solution or switch to a newer one will also mean the need for staff training to use the updated software.

Investment 360

  • Businesses invest in search, purchase, implementation, customization, and licensing their legacy solutions, so abandoning them in favor of new ones may seem like a waste of money.

  • Sometimes projects related to the migration from legacy systems can be costly and time-consuming, so often decision makers decide to allocate budgets towards initiatives where they can quickly see profitability.

  • If the old system fulfills its functions and is still satisfactory, then modernization may be perceived as a risk from a financial point of view.

Coping with Challenges
When a solution is outdated, it may have certain technical issues. The organization is aware of these issues, and users are able to use the solution even if there are some difficulties. However, over time, the system may frequently crash, freeze, or have problems accessing data or executing certain options, which leads to the realization of the need for legacy system migration.

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.
Cloud technology is not a novel concept, but its progress has been extraordinary. Its significance in modern architecture is tremendous, as it serves as a base for constructing, constructing, and preserving applications and services in a novel way. The cost-effectiveness of cloud computing is debatable; however, the correct management can save you money and provide you with possibilities to grow your business, which was probably only possible after.

There are fantastic public cloud services, and it is not suitable to consider the pros and cons of AWS, Azure, GCP, etc., or your platform strategy in this context. A well-laid plan is essential; you can opt for a single platform, a hybrid option, or a multi-platform architecture.

The approach should be consistent, whether it's hybrid (cloud and on-premise/managed data center), multi-cloud, or a single consolidation cloud platform. The architecture, tools, and methods used must be appropriate for the chosen approach.
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.
During the application migration, aspects such as DevOps and Cloud are important. Cloud development also contributes to the simple application deployment process. Modern cloud platforms provide the core options for CI/CD and deployment automation. DevOps/DevSecOps practices enable businesses to deliver developed solutions. The right balance between releasing new functionality and ensuring reliability is important.
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.

Why Your Apps Need Migration

Optimize your solutions portfolio Optimize your solutions portfolio
Optimization of the Existing Solutions

When applications become obsolete, an organization may face certain challenges related to the stable operation of the application or the inability to add certain features, etc. Reworking obsolete applications allows you to ensure the smooth functioning of systems, perform their appropriate work, and ensure business growth.

Scale as business needs change Scale as business needs change
Fast Solution Scaling

As a business grows, it has more needs, and it makes sense to expand its solutions. For example, by migrating legacy systems to newer architectures like microservices, the application can be quickly extended and new functionality added without taking up much developer effort.

Deliver world-class user experiences Deliver world-class user experiences
Offer Up-To-Date User Experience

More modern solutions are focused on simplicity combined with business value. If a solution is easy to use and understandable from the user’s perspective, then it becomes an effective tool in their activities.

Drive innovation Drive innovation
Following Modern Trends

When the company is up-to-date and follows modern technology trends, it has higher chances to attract more customers. Also, if the organization gives customers something new, modern features, then they are more inclined to buy the product that meets their expectations.

Migration Types

App Migration Strategies

Application Rehosting
Application Replatforming
Refactoring/Rearchitecture
Application Rehosting

This type of legacy migration means the transfer to another environment from the current one without global changes in the app’s architecture/code. This system migration is aimed at the reduction of the costs for the infrastructure and continued stable functioning of business operations.

Application Replatforming

This type of migration foresees the movement to another environment, including certain changes in the solution’s code and architecture. This option needs more effort and is aimed at the reduction of operational costs, usage of the platform capabilities, improvement of the scalability, and making the first step to the incremental modernization of the app.

Refactoring/Rearchitecture

This is a more complex strategy for the legacy application migration that involves restructure and the rework of the application to be compliant with modern standards and software architectures. This is a rework with the long-term benefits for future application scalability and easy maintenance.

Main Benefits of the Migration

Businesses that make decisions to migrate the outdated apps to modern technologies and approaches have many benefits, and here is the list:
