Vistara :The First Indian Airline Born on the AWS Cloud
TATA SIA Airlines Limited, known as Vistara, commenced commercial operations in 2015 with an aim to set new quality standards in India’s aviation industry. Today, it connects 32 destinations across the country, operating more than 200 flights a day. Vistara has flown more than 18 million customers since launching operations.
“Since using AWS services, we have never faced a single instance of downtime.”
Subhash Mishra, Head of IT Enterprise, Vistara
Digital Innovation at Its Core
India’s aviation market has grown rapidly in the past five years, with a surge in the traveling population giving rise to fierce competition in the industry. Vistara, one of India’s most well-known full-service carriers, launched in January 2015 as a joint venture between India’s Tata Sons and Singapore Airlines. Vistara now connects 32 destinations and operates more than 200 flights a day, served by a fleet of 32 aircraft. Digital innovation is at the core of the company’s DNA and enables Vistara to achieve its competitive edge.
Subhash Mishra, Head of IT Enterprise at Vistara, has more than eight years of dedicated experience working on the cloud and was among the first cloud adopters in India. He understood the importance of the cloud and its agility to launch new workloads quickly and cost-effectively. Mishra chose Amazon Web Services (AWS) due to its maturity in the market, pay-as-you-grow model, and security features. “When we started evaluating different public cloud providers, AWS emerged as the clear winner in terms of depth and breadth of services,” Mishra says.
Three Engineers Manage over 180 Servers
Vistara is running nearly all workloads on the AWS Cloud. This includes mission-critical ones such as its enterprise applications, digital workloads, infrastructure and security workloads for security operations centers (SOCs), network operations centers (NOCs), and CyberSOC. Mishra and two other engineers manage all its servers, architecture, and operations to maintain strong business continuity. Building a new workload — from planning to architecting to deployment — happens in six hours or less. Mishra says, “With an on-premises infrastructure, this would have taken us several weeks or months, and Vistara would not have been able to grow as fast to become what it is today.”
He adds, “We have run close to 20 proofs of concept in the past year, testing new initiatives and workloads, and AWS offers us the agility to spin up the test and production environments in minutes with a pay-as-you-go model.”
