Legacy System Modernization Approaches

A. Re-platforming, or re-hosting

This powerful modernization approach lets companies migrate their existing systems who a cloud-based ecosystem without expansive code changes.

Think of it like rearranging the furniture around the house.

Here’s why this approach is popular:

1. Fast & efficient processes This approach allows the modernization process to have as little disruption as possible on other systems. This is because it takes much less time to employ this approach.

2. Cloud Benefits Delivered This approach lets businesses reap the benefits of cloud computing: scalability, expansion & seamless integration. These benefits can be availed without even a complete system overhaul.

3. Reduced Reliance on Hardware Such an approach lets every system capture a space in the World Wide Web. This allows businesses to let go of expensive & unmaintainable systems, making room for additional flexibility.

Although there exist some minor code changes or database modifications here & there, the approach offers a smooth transition of multiple applications.

B. Rewrite

This approach includes developers rewriting the existing legacy code & building it anew. This process has two ways to function: manual & automated.

Manual efforts let dedicated developers offer complete control over the new system. However, it can take a significant time frame to achieve the required results.

Now, there exist automated tools to rewrite the code, accelerating the entire process.

Regardless of the path chosen, rewriting offers a fresh start for companies to break free of the tried & tested moulds.

C. Replacing with Ready-Made Solutions

For many companies, directly replacing legacy systems with commercial solutions can be implemented effectively.

These off-the-rack solutions let businesses avail themselves of pre-built functionalities & workflows that integrate smoothly with current systems.

Such solutions carry readily available features, security updates & compliance capabilities. Additionally, it lets companies to future-proof their systems with the use of newer technologies.

D. Retaining the Current System

Even when completely modernizing a legacy system is preferable, let’s explore an approach where the companies tend to retain them.

This happens due to:

1. Systems being a perfect fit Current systems are built for delivering the exact functionality a business needs.

2. User Comfort Many stakeholders, such as all the employees, including the C-suite level associates, are already comfortable using a set system.

3. Complexities in Integration Choosing a complete overhaul while modernizing legacy systems disrupts the ongoing integrations with existing processes.

4. Limited Use This refers to when the legacy system is only utilized whilst auditing or any compliance related reasons.

In a case like this, companies have the options to archive the system for a low-cost solution or customize it heavily to just generate reports from it.

E. Using DevOps for Legacy

Many businesses have started relying on a DevOps solution to facilitate the process of legacy system modernization. This lets businesses constantly integrate new or updated code into a single codebase.

This results in streamlined processes to build & deploy error-free code later and faster.

What are legacy systems?

In the iterative realm of information technology, legacy systems refer to yesterday’s cutting-edge solutions. These systems can range from enterprise applications, software platforms, or any IT infrastructure

Companies usually look to revitalise or modernize these systems, catering to its name. These can quickly become outdated due to the following reasons:

1. Technology becoming Obsolete: Advancements & newer updates in hardware, software & security systems can make old legacy systems’ functionalities incompatible with modern IT environments.

2. Limited Integration Capabilities: Integrating legacy systems with these new gen technologies can result in heavier mental load & resource-intensive processes.

3. Maintenance Challenges: Vendor Support for established legacy systems is often unreliable. This causes companies to face ground-level challenges of finding qualified workers for maintenance & support.

4. Security Vulnerabilities: A legacy system’s code, being developed in the past without any current support, can contain unaddressed security flaws, making them & their data susceptible to hackers & cyberattacks.

Discovering the Impact of Legacy Systems

Outdated legacy systems can restrain innovative efforts, further affecting a business’s agile approaches. This can lead to:

1. Lessened Productivity: Heavy effort-taking processes paired with outdated processes results in frustrating, slowed-down workflows.

2. Higher Costs: Maintaining an unreliable legacy system can take up significant resources that could be invested elsewhere.

3. Limited Future Scalability: Legacy systems mostly struggle to changing needs, integrations, and all growth-related efforts.

4. Security Burdens: Legacy systems having unaddressed vulnerabilities can pose a consistent security threat for companies.

Let’s get into the solution!

Within the modern, cloud-centric IT landscape, legacy systems act like the core infrastructure layers. By encompassing both software & hardware parts, these systems are the technological bedrock on which major business processes operate.

Trends show that even after being essential, legacy systems are maintained, but not iterated, or upgraded to match the modern needs of users.

But, as more and more businesses become agile & new gen, this maintenance may cause unnecessary burdens, pausing growth & success.

Legacy system modernization, thus, brings forth a new wave of business success. By retiring the outdated software, businesses get better functionality & modern development capabilities.

Businesses, however, may approach this need for change in the following two ways:

Legacy Application Modernization

Think of this as a complete system overhaul. This approach refers to breathing new life in the existing systems by upgrading the core components & functionalities to meet the modern requirements.

Here’s how some companies achieve this:

a) Refactoring This means restructuring the legacy code to facilitate enhanced readability, maintainability and overall performance. This can result in increased efficiency, and clears the path for future growth, & scalability through feature enhancements.

b) Re-platforming Systems with outdated hardware & software limitations can heavily detain your system’s potential. Re-platforming involves essentially migrating your system to a new, cloud-based platform.

This gives companies benefits like:

1. Increased chances of scalability

2. More platform-based flexibility

3. Widened access to cutting-edge features

c) Microservices Architecture Here, dedicated developers break down the older systems into smaller, independent services. This approach results in faster development cycles, easier deployments, and a simplified maintenance process.

Each of the developed microservices can be developed & scaled independently, allowing for higher agility & resilience.

2. Legacy System Migration

Sometimes, the system demands a complete replacement. Legacy system modernization, thus, involves eradicating the existing system, and implementing a brand new, modern one.

Here are some strategies developers employ:

a) Lift & Shift Basically, this is a quick approach that transfers the legacy system ‘as-is’ to a new hardware or cloud-based environment. This is a temporary fix, or the first step taken while migrating the legacy system.

Just transferring the system doesn’t address any underlying issues with code or architecture.

b) A Complete Overhaul This is where developers decommission the entire legacy system, and begin implementing a new one built from scratch. While being disruptive & resource-intensive, it offers a unique opportunity:

– Companies can easily adopt the latest technologies & functionalities.

– Developers can build the fastest performance.

– You achieve an efficient system.

c) Phased Migration This method allows developers to have more control with the system transition. The system’s components are migrated in stages, reducing heavy disruption in ongoing operations.

This method is highly preferable when a complete system overhaul is too risky or time-consuming

How To Choose?

Deciding on the ideal method depends on these considerations:

1. Complexity & Criticality of Existing Legacy System Legacy systems that are highly complex can be modernized using the phased approach. This reduces disruption and allows more control over the revamping.

2. Budget & Resource Constraints Legacy system modernization demands an upfront investment while refactoring or re-platforming, however, exporting the system in an as-is condition might be more cost-effective

3. Getting the Right Business Outcome Aligning business goals with each approach is crucial. One might prioritize being cost-friendly, while the other may want to add some new features.

The approaches mentioned provide numerous benefits, but it’s required of developers to properly analyze each method and choose the one that works best for their scenario.
