API Scaling and Performance

Modern APIs must cope with high load, peak requests and parallel calls. We design and implement solutions that enable smooth scaling and consistent performance even in high-volume environments.

We use best practices: horizontal scaling, caching, queues, asynchronous calls, CDN and load balancing.


Approaches to scaling

MethodDescription
Horizontal scalingIncreasing the number of API instances under load
Load balancingDistribution of requests between servers (HAProxy, Nginx, AWS ELB)
CachingQuick access to frequently used data (Redis, Memcached, CDN)
Asynchronous processingPending tasks through queues (RabbitMQ, Kafka, Celery)
Rate Limiting и ThrottlingControl the flow of requests from clients

Performance optimization

Analysis of bottlenecks by logs and metrics
  • Support for batch requests and minimization of roundtrip
  • Using HTTP/2, compressing, merging responses
  • Code profiling, refactoring, and latency reduction
  • Load testing (k6, JMeter)

Business results

Reliable operation even with a sharp increase in traffic
  • Ready to scale at any time
  • Reduce costs through efficient resource allocation
  • Predictable performance and fault tolerance
  • Fewer incidents and manual responses

Where especially important

Mobile and web applications with a large number of users
  • Financial and Transaction Services
  • Highly active gaming platforms
  • API-first products and SaaS solutions

The API should not be a narrow neck of the system. We create a scalable, peak-resistant, easy-to-maintain, and growth-ready architecture without sacrificing performance or stability.
