2025 Reflection: Looking back nearly a decade, the infrastructure transformation described in this article was part of the broader cloud-native revolution. In 2016, we were transitioning from monoliths to microservices, from physical data centers to cloud, from manual scaling to auto-scaling. These weren’t just technical changes—they represented a fundamental shift in how we think about infrastructure.
How the Landscape Has Changed:
Kubernetes Everywhere: What was experimental in 2016 is now ubiquitous. Kubernetes has become the OS of the cloud.
Serverless Maturity: Functions-as-a-Service evolved from niche use cases to mainstream architecture patterns.
Observability Revolution: We’ve moved from “monitoring is working” to “understanding system behavior through traces, metrics, and logs.”
Platform Engineering: The emergence of internal developer platforms has abstracted infrastructure complexity, letting developers focus on business logic.
Multi-Cloud Reality: What started as vendor lock-in concerns evolved into genuine multi-cloud deployments with abstraction layers.
Edge Computing: CDNs evolved from static asset delivery to full compute platforms at the edge.
What Hasn’t Changed:
- Performance matters: Users still expect <1s page loads; slow websites lose customers
- Scalability principles: The CAP theorem still holds; trade-offs remain
- Cost consciousness: Cloud bills can spiral; optimization is ongoing
- User experience first: Technology serves users, not the other way around
For Modern Infrastructure Engineers:
If you’re building scalable platforms in 2025, consider:
- Start cloud-native: Containerize from day one, design for Kubernetes even if you’re not using it yet
- Observability first: Instrument your code before problems arise; you can’t debug what you can’t see
- Automate everything: Manual toil doesn’t scale; invest in automation, CI/CD, GitOps
- Security embedded: Don’t bolt it on later; zero-trust from the start
- Cost visibility: Tag everything; understand unit economics (cost per user, per transaction)
- Developer experience: Platform teams serve developers; make it easy to do the right thing
- Learn fundamentals: Kubernetes abstracts VMs, but understanding networking, storage, compute remains critical
The Indian Tech Context (2016 vs 2025):
In 2016, Indian tech companies were adopting cloud cautiously, often hybrid cloud. By 2025:
- Hyperscale adoption: Indian unicorns run entirely on cloud (Flipkart, Paytm, Swiggy)
- Data residency: RBI mandates drove Indian data center regions
- Mobile-first: India’s mobile internet boom demands mobile-optimized infrastructure
- Cost sensitivity: Indian market’s price sensitivity demands extreme infrastructure efficiency
- Global scale: Indian companies now serve global audiences, requiring worldwide infrastructure
The job portal and movie site I helped scale in 2016 were part of India’s digital transformation. Today, India is a major player in global tech, and the infrastructure principles we pioneered—scalability, performance, cost-efficiency—remain relevant.
For modern infrastructure challenges, the technology has evolved but the principles endure: understand your domain, measure everything, scale intelligently, never stop optimizing.
