A nationwide digital learning initiative brought together millions of learners over a short period, creating one of the largest coordinated online learning events in the country.

The initiative recorded:

• 3.18 crore course completions
• 4.48 crore hours of learning
• 33 lakh+ employees completing their learning targets

But numbers alone don’t explain what really happened.
To support this level of participation, the platform had to handle millions of concurrent users, continuous data generation, and sharp traffic spikes all in real time. That requirement shaped every architectural decision underneath.

Built for Scale, Not Adjusted to It

To begin with, the platform needed an infrastructure that could scale proactively, not reactively. It was built on Google Cloud Platform using a hybrid infrastructure approach, with Amnex as the cloud infrastructure ecosystem partner.
The architecture combined:

• Google Kubernetes Engine for containerized, dynamic workloads
• Compute Engine for stable backend services

This separation ensured that scaling compute-heavy workloads wouldn’t impact core system stability. Once the compute layer was designed to scale, the next challenge was managing the data generated at that scale.

When Millions Learn at Once, Data Becomes Critical

At peak usage, the platform was continuously processing data. Every interaction, such as course access, progress tracking, and certification, added load to the system.
To ensure this didn’t become a bottleneck:

• Databases were deployed in clustered configurations
• Systems were built for horizontal scalability
• Real-time storage monitoring tracked usage thresholds
• Automated workflows enabled zero-downtime storage expansion

This ensured that data growth scaled in parallel with user activity.
With both compute and data layers prepared, the system still needed to handle one of the hardest problems:

Handling Sudden Traffic Surges at Extreme Throughput

Traffic did not build gradually. It surged sharply during periods of high engagement.

To absorb this, the entry layer was designed for extreme throughput.
Google Cloud Load Balancing was configured to handle up to 2 million requests per second, ensuring incoming traffic was evenly distributed from the first touchpoint.

This traffic then passed through two Fortinet firewalls in High Availability (HA) mode, adding a layer of security and redundancy before reaching the application layer. Behind this:

• Google Kubernetes Engine operated with multiple node pools
• Autoscaling dynamically aligns resources with real-time demand

This architecture ensured that even at peak load, the platform sustained 160K+ transactions per second in production.

Ensuring Real-Time Visibility for Performance at Scale

With multiple layers operating simultaneously, the system needed deep observability to detect and resolve issues instantly.
A multi-layered monitoring stack was implemented:

• Native monitoring through GCP
• Custom dashboards built on Grafana and Prometheus
• Integration with database exporters and API Gateway exporters for granular insights

To make this data actionable:

• An AI-driven reporting system was integrated
• It generated summarized insights across infrastructure and application layers
• Reports were delivered directly via WhatsApp, enabling faster response cycles

This ensured that issues were identified and addressed before impacting users.

Where Scale and Reliability Translate into Inclusive Reach

The infrastructure did not just support scale. It enabled reach across diverse user groups.

• 77 lakh+ course completions in Hindi and regional languages
• 22.87 lakh learners certified under AI Daksh

This reflects a system that was capable of serving diverse users across geographies, languages, and digital access levels.

The Invisible Layer That Made It Possible

While multiple ecosystem partners contributed, the cloud infrastructure layer remained the backbone.
As the cloud infrastructure ecosystem partner, Amnex ensured that:

• Scaling happened in real time, without disruption
• Systems remained stable under unpredictable load patterns
• Performance stayed consistent across all interactions

At this scale, infrastructure is no longer invisible. It directly defines user experience.

What This Signals Going Forward

This initiative demonstrates how Amnex engineers cloud infrastructure for real-world, high-pressure digital environments.

From designing elastic architectures to enabling real-time observability, every layer was built to perform under sudden, massive demand without disruption. As India’s digital public infrastructure expands, the expectation is no longer about systems that work in ideal conditions. It is about systems that hold steady when millions engage at once.

At Amnex, that is the benchmark we build for.
