Zero-downtime migration of a monolithic e-commerce platform to microservices on AWS, cutting infrastructure costs by 40%.

A leading West African e-commerce platform faced frequent crashes during flash sales due to its monolithic PHP architecture. We containerised the monolith into 6 microservices (Docker/Kubernetes), built CI/CD pipelines (GitHub Actions), and used a blue-green deployment strategy. The cutover was seamless, and the new architecture auto-scales to handle 10x peak traffic.

Project Timeline

Assessment & Architecture Design

01 Nov 2025

Mapped 6 core domains and designed ECS Fargate architecture.

Containerisation

15 Dec 2025

Dockerised all services and set up staging Kubernetes clusters.

CI/CD & Load Testing

15 Jan 2026

Implemented pipelines and simulated 10x flash-sale traffic.

Blue-Green Cutover

15 Feb 2026

Switched DNS with zero downtime; green environment went live.

Challenges

Ensuring database consistency during the split of a monolithic MySQL database into service-specific Aurora clusters.

Results

Zero downtime, 40% cost reduction, 50% faster deployment cycles, and successfully handled 10x Black Friday traffic.

Common Questions

We build both

electrosoft NIGERIA combines software engineering, electronics, electrical engineering, embedded systems, artificial intelligence, automation, robotics, connectivity, and digital platforms

Depending on the project, we can deliver software alone, physical technology alone, or an integrated end-to-end system where hardware, software, data, and automation work together.

We design and deploy intelligent engineering and automation solutions.

You do not necessarily need to replace what you already have. We can assess your existing infrastructure, applications, equipment, processes, and communication systems and determine what can be automated, integrated, upgraded, or replaced. Where practical, our approach is to build on useful existing assets rather than forcing an organisation into an entirely new system.

Project duration depends on the complexity of the solution. Smaller automation and software projects may take a few weeks, while integrated industrial, energy, robotics, healthcare, infrastructure, or institutional systems may require several months. After an initial discovery and technical assessment, we provide a defined scope, implementation roadmap, milestones, and estimated delivery timeline.

Yes. We can provide post-deployment maintenance, monitoring, troubleshooting, system upgrades, security updates, performance optimisation, technical support, and continuous improvement. For systems involving physical infrastructure, we can also support operational monitoring and engineering maintenance requirements.

Yes. We can work alongside your existing engineering, IT, operations, management, or technical teams. Depending on the engagement, Electrosoft can act as the principal technology partner, a specialist engineering team, or an implementation partner while providing documentation, training, knowledge transfer, and technical handover.

Yes. Our solutions can serve individuals, households, SMEs, corporations, factories, farms, schools, universities, healthcare organisations, professional organisations, community platforms, government agencies, and other institutions. The appropriate technology and level of engineering are determined by the specific problem we are solving.

Our projects are generally quoted according to scope rather than using a fixed price list. We consider the technical requirements, hardware and software components, integrations, infrastructure, development effort, deployment environment, security requirements, support needs, and project complexity. We first understand the problem and then prepare an appropriate technical and commercial proposal.

Yes. We can work from an early concept, engineering problem, business requirement, prototype, or existing system. Depending on the project, our work can include feasibility analysis, system architecture, research, prototyping, software development, electronics and embedded engineering, AI integration, testing, deployment, and further product development.

Start by booking a free discovery call or contacting our engineering team. We will discuss the problem you want to solve, understand your objectives and existing infrastructure, identify the appropriate engineering approach, and determine whether Electrosoft can build or deploy the required solution. Where appropriate, we then proceed to technical discovery, scope definition, proposal, and implementation.
