Should You Rehost, Rebuild, or Rewrite a Legacy Application With Latest Software?
We revealed each of these modernization approaches and compared them to make the decision-making process easier for you.
Legacy System Architecture Improvement Services
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
You need legacy architecture modernization services if:
YOUR SYSTEM IS A COMPLICATED TANGLE OF TOO MANY INTERCONNECTIONS
PROCESSING REQUESTS TAKES MUCH MORE TIME DUE TO LOW PERFORMANCE
THE APP IS NOT INCOMPATIBLE WITH THIRD-PARTY TOOLS
YOU WANT TO PREPARE THE APPLICATION FOR CLOUD MIGRATION

JUST A PIECE OF ADVICE
As an architect, you design for the present, with an awareness of the past, for a future which is essentially unknown.

Our Architecture Improvements Rules:
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
The Process of Re-Architecting Software Systems
Assessing the Current System
We determine problem areas in the legacy solution and generate ways to improve the architecture.
Planning
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.
Building a transitional architecture, if needed
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 It is especially necessary when we work with outdated systems that need to continue operating.
Rolling out the pilot
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.
Implementing the system
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.
Maintaining the system
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.
What Should Be Done After
Transition
Although the complicated process of modernization of legacy architecture is completed, it is still necessary to consider the following organizational factors of your architecture improvement:
-
DevOps should revamp builds and plan for continuous integration
-
Tech writers must update documentation
-
Program managers should learn about new system dependencies
-
HR should look for new specialists to hire
A piece of adviсe
Conway’s law says that architecture follows organization and vice versa, so a change in architecture requires a change in organization and people.
I Don’t Know If I Need the Modernization of Legacy App Architecture
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.

FROM MONOLITH TO MICROSERVICES
A microservices architecture consists of loosely coupled services that can be developed, deployed, and maintained independently. 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.

THE KEY BENEFITS OF MICROSERVICES FOR THE COMPANY ARE THE FOLLOWING:
Improved fault isolation
If there is an error in one area of service, the entire app will not stop performing.
Agility
Independent services mean easier updates, bug fixes, system upgrades and feature releases, because you won’t need to redeploy the entire app.
Scalability
Transform the system whenever you want by scaling out subsystems without scaling the entire app.
