Web Server Load Balancing with NGINX Plus

Real‑time APIs have become part of our daily lives. From ordering food to buying and selling stocks using our mobile phones, many day-to-day activities entail interaction with real‑time APIs. But what does this look like from the perspective of the API publisher? What market demands are driving companies to serve APIs in real time? How are NGINX customers achieving real‑time performance? Let’s look at some examples.

Managing API Traffic at Scale for a Microservices‑Based Application


African Bank was founded in 2016 in South Africa to provide digital banking services to underserved and rural customers. They built a modern application from the ground up using microservices.


A sophisticated microservices architecture based on a reference architecture from NGINX provided speed-to-market and cost advantages, but introduced complexity around API scalability and inter‑service communication.


The bank replaced Apigee, a legacy point solution for API management, with NGINX. The NGINX Controller API Management Module complements the existing NGINX microservices deployment with CI/CD integration and monitoring for SRE teams.

Processing a Large Volume of Credit Card Transactions in Real Time


A leading U.S.‑based financial services corporation is adopting the Open Banking Standard, which provides API specifications for sharing of customer‑permissioned data and analytics with third‑party developers and firms that are building applications and services. This is driving the need to support increased API volumes and provide API-Management-as-a-Service.


The incumbent API management solution added 500 milliseconds (ms) of latency to every API call. To avoid adverse impact to revenue as it transitions to Open Banking, the customer needed a solution that processed API calls with latencies under 70ms.


The customer deployed the NGINX Controller API Management Module. API processing time is consistently below 10ms – exceeding their performance requirements by 85%.

Powering Digital Transformation with Real‑Time APIs


A leading telecom organization in the Asia‑Pacific region embarked on digital transformation initiatives that require processing 600 million API calls per month for 800 different APIs.


The incumbent API management solution was too expensive and slow for the high volume of internal API traffic. The customer also wanted to augment and empower their DevOps teams with self‑service API management.


The NGINX Controller API management solution sits “beside” the legacy API management solution. The NGINX solution reduced latency by 70%, while also enabling self‑service for DevOps to create, publish, and monitor APIs. DevOps teams were able to increase API release velocity by integrating API management tasks into their CI/CD pipelines. They achieved significant savings in time and effort by automating routine tasks such as API definition and gateway configuration using APIs.
