Restack Empowers Fintech Business with Enhanced Agility and Optimisation

The Challenge

The MTN Telco buyout of aYo Holdings created the opportunity to make aYo a cloud-first, cloud-only Fintech business that needed more agility as well as cost optimisation while implementing an aggressive expansion roadmap into Africa.

The Solution

We successfully migrated all line-of-business applications—including Core LOB systems, engagement platforms, integration platforms, and USSD platforms—along with ERP systems such as Payroll, General Ledger, and Cashbook. Additionally, we transitioned EUC capabilities from Google Suite to O365 and implemented Power BI reporting. This extensive project also involved moving the on-premise IBM DB2 data warehouse to a cloud-based data warehouse. This comprehensive migration spanned 5 countries, served over 15 million clients, and supported more than 1,000 staff members.

The Benefits

Today, the business operates entirely in the cloud, eliminating the need for on-premise systems, data centres, and associated dependencies. We assembled a dedicated team that achieved this transformation in record time, ensuring minimal downtime. This shift has enabled the business to boost revenue through increased agility, safeguard gross profit with robust, highly available infrastructure, and reduce operational expenses via reserved instances. As a result, the cash flow has stabilised, aligning seamlessly with revenue growth.

AWS Services
Restack implemented Infrastructure as Code (IaC) foundations and migrated all on-premise services into a landing zone for aYo Holdings, encompassing multiple management groups and subscriptions. This was executed within the client’s own tenant and included network and security configurations, hosted infrastructure (such as SQL databases, virtual machines, and Kubernetes clusters), Azure AD, and security and tagging policies. The project enabled the rollout of both existing and new country IT infrastructures via DevOps pipelines, which were configured with manual and automated stage gates. One of these automated gates ensured best practices and security checks through policy as code.
