THE CHALLENGE:
Our customer, a leading life insurance company in India, embarked on journey to expand their horizons, by launching new products and innovating new ways of engaging their customers. Application modernisation was one of the approaches finalised, with upgrades for both, their internal and external facing applications. Over the years, and as applications grew, this naturally led to a multi cloud environment, and the strategy required an overall transformation for the cloud. The incumbent IT architecture followed the traditional model, where the data center performed the hair-pinning role for all types of data flows – whether cloud to cloud, branch to cloud and even the agents to cloud. Scalability was also a missing feature, where every additional cloud required the creation of new landing zone replicating the existing AWS architecture principle.
THE SOLUTION:
Tata Communications proposed a 2-landing zone philosophy – a first for the customer. One IZO™ Multi Cloud Connect landing zone was meant for internal applications, while the other would work for the external applications. The landing zone philosophy offers scale, simplicity & cost efficiency for the customer:
- Scalability: A common landing zone allows for the options to continue adding more clouds as applications continue to get added. The architecture also supports the addition of a disaster recovery (DR) site, which the customer is planning in the near future.
- Simplicity: This solution completely eliminates data center hair-pinning – which is not an efficient architecture for critical cross-cloud communication – with multi cloud hub acting as the gateway for cloud-to-cloud communication.
- Cost efficiency: Such a common landing zone reduces the internet egress costs for all the 4 clouds, thereby delivering ~30% or more internet data egress cost efficiency.
THE RESULTANT OUTCOMES FOR THE CUSTOMER:
The customer gets a refreshed multi cloud IT architecture, underpinned by the 2-landing zone solution from Tata Communications – a first for us. This leads to a reduction in network & security licenses for multiple clouds, and thus, adds to the simplification as well as life cycle cost savings to the tune of 25-30%, apart from the egress cost savings mentioned earlier.
WHAT WE LEARNT:
Traditional IT architectures continue to add on additional clouds & applications – both internal and external – and create complex and cost inefficient estates. Digital transformation and application modernisation initiatives are great reasons for enterprises to reimagine these multi cloud estates and innovate to simpler, more scalable and cost-efficient setups.

In today’s fast-paced digital world, legacy systems can quietly become a company’s biggest bottleneck. Outdated applications may still “work,” but they often drag down performance, limit scalability, and eat up IT budgets. That’s where application modernisation steps in—a strategic move to breathe new life into old systems. By updating software architecture, infrastructure, and features, businesses can unlock agility, enhance security, and stay competitive. Whether it’s moving to the cloud, adopting microservices, or revamping user interfaces, modernisation is no longer optional—it’s essential.
