A leading mobile-operator in Sri Lanka used to run all of its Value-Added-Services such as missed call alerts, ringing tones and news updates, on standard server infrastructure. They were running hundreds of VAS applications with every app requiring a server of its own. These applications were real-time and required specific hardware provisioning, resulting in significant CAPEX and OPEX investments to install and maintain servers, taking a massive toll on the electricity bill.
Due to seasonal workloads, they were even forced to maintain an over-provisioned server hardware infrastructure. Aside from this, launching VAS applications were a time consuming endeavor, as new servers had to be ordered and installed prior to launching new services. This made it difficult for the business to compete in the marketplace as service launch times were lengthy, making it impossible to launch services fast, as-and-when needed.
By adopting server virtualization at a time when it was a nascent technology, the mobile-operator reduced their VAS server hardware footprint from almost 200 physical servers to 6 blade servers. This not only significantly reduced the cost of maintaining servers, but it also gave them the ability to launch applications within just hours by creating virtual machines as needed. Today, over 400 VAS applications run smoothly on 12 servers!
This was an era where virtualization was unheard of, but the company boldly took the opportunity and became the first Telco in all of South-Asia to run complex VAS applications on virtual platforms. N*able brought this solution to them and revolutionized the entire VAS industry by challenging conventional wisdom, resulting in increased agility and business efficiency.
