Legacy Systems 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 TANGLE OF INTERCONNECTIONS BEYOND CONTROL

PROCESSING REQUESTS TAKES MUCH TIME DUE TO LOW PERFORMANCE

THE APP IS 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 Principles:

Don’t underestimate the project complexity

Don’t change the architecture without a strong need

Build transitional architecture in case of 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

01 Assessing the Current System
02 Planning
03 Building a transitional architecture, if needed
04 Rolling out the pilot
05 Implementing the system
06 Maintaining the system

Assessing the Current System

We determine problem areas in the legacy solution and generate ways to improve the architecture.

Planning

We design target architecture based on assessment results and carefully plan the entire process with minimal business disruption while still moving towards modernization.

Building a transitional architecture, if needed

In the case of extensive changes, we prototype and build a transitional system — a temporary structure to create the final architecture. It’s especially necessary when we work with systems in production that need to continue operating.

Rolling out the pilot

In the case of extensive changes, we prototype and build a transitional system — a temporary structure to create the final architecture. It is especially necessary when we work with outdated systems that need to continue operating.

Implementing the system

After the new system is checked and de-bugged, we can implement it into production, mindful of the fact that it’s only the beginning of re-architecture.

Maintaining the system

To enable the system to stand the test of time, you should remember what maintenance tasks to do 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 continuous integration
Tech writers have to update documentation
Program managers should learn about new system dependencies
HR should look for new skillsets 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.
