Istio

When eBay needed to secure and manage communication between over 1,000 microservices handling millions of transactions daily, they implemented Istio as their service mesh solution. The platform immediately provided mutual TLS encryption for all service-to-service communication, comprehensive traffic management, and deep observability without requiring any code changes to their existing applications. Within six months, eBay reduced security incidents by 85% and improved their mean time to resolution for production issues by 60% through Istio’s powerful telemetry and traffic management capabilities.

Istio has emerged as the de facto standard for service mesh architecture, adopted by organizations ranging from startups to Fortune 500 companies managing complex microservices environments. IBM uses Istio to power their cloud platform services, leveraging the mesh’s ability to provide consistent security, observability, and traffic management across hybrid cloud deployments. With Istio managing over 500,000 service instances across IBM’s infrastructure, the platform demonstrates its capability to scale enterprise workloads while maintaining performance and reliability.

What sets Istio apart is its comprehensive approach to microservices challenges, addressing security, observability, and traffic management in a unified platform. T-Mobile relies on Istio to implement zero-trust security across their customer-facing applications, using the platform’s automatic mutual TLS and policy enforcement to protect sensitive customer data. The service mesh processes over 2 billion requests daily for T-Mobile while providing detailed metrics and tracing that enable their engineering teams to optimize performance and quickly identify issues across their distributed architecture.
