Mintyn’s Well-Architected Review

Introduction

Managing your cloud infrastructure can get really complex: the hidden charges, some idle services you left running, and overprovisioned resources that drain budgets. It’s a challenge many businesses face, and to tackle this, an in-depth review with efficient solutions must be taken to make your AWS environment more cost-effective.

Client Overview

Mintyn Bank, a digital product under Finex Microfinance Bank, offers an effective and innovative banking experience designed to serve both personal and business needs. Founded in 2020, Mintyn eliminates traditional banking fees such as Cost of Transfers (COT) and account maintenance charges. With a focus on free banking, and accessibility through its mobile app, Mintyn stands out as an alternative to traditional banks.

However, while leveraging AWS services for their digital banking operations and to serve different users, they faced high cloud costs. To solve this, Mintyn MFB partnered with CloudPlexo, an AWS advanced partner to implement a more cost-efficient solution.
