Consider These Things Before Legacy Application Re-architecting
Is it time for re-architecting the legacy software in your company? Be aware of all the pitfalls, risks, and challenges.
Even the most well-written code will not work properly within a solution with poor architecture. Modernizing legacy architecture offers many benefits, starting from better system performance and ending with higher interoperability. Migration to the cloud environment also requires architecture improvements to reduce future hosting costs.
Architecture improvements
Architect
As an architect, you design for the present, with an awareness of the past, for a future which is essentially unknown.
Architect
Do not underestimate a project’s complexity
Do not change the architecture without a valid reason
Build transitional architecture when making considerable changes
No “Big Bang” deployments
Perform a pilot rollout of a new architecture to validate the system
Create solutions that will stand the test of time
We determine problem areas in the legacy solution and generate ways to improve the architecture.
We design the target solution architecture based on the results of our assessment and carefully plan the entire process to minimize business disruption while modernizing the product.
In the case of extensive changes, we prototype and build a transitional system — a temporary structure for you to use while we create the final architecture. It is especially necessary when we work with outdated systems that need to continue operating.
During this time, the new system will be validated; we will be relying heavily on the transitional architecture to enable the roll-back and roll-forward of the architectures without impacting users.
After the new system is checked and de-bugged, we can implement it into production, mindful of the fact that re-architecture isn’t complete without proper maintenance.
To ensure that the system can stand the test of time, you should remember to maintain the system after the technical stage of re-architecture.
A piece of advice
Conway’s law says that architecture follows organization and vice versa, so a change in architecture requires a change in organization and people.
In case you’re not sure about the state of your architecture, there are assessment and audit options that will expose the reasons for low performance or any other issue. It will simplify the decision-making process for you.

Each of these services is responsible for discrete tasks, but in case of larger complex business problems, they can communicate with other services through simple APIs.

If there is an error in one area of service, the entire app will not stop performing.
Independent services mean easier updates, bug fixes, system upgrades and feature releases, because you won’t need to redeploy the entire app.
Transform the system whenever you want by scaling out subsystems without scaling the entire app.
