Calculating the cost savings
of moving to the public cloud

We recently built a model for one of our customers, and determined they would save 60% on their TCO over five years. Discover how!

When a communications service provider (CSP) evaluates a migration to the public cloud, the IT department often approaches it as a “lift and shift” exercise. In other words, they scope taking what they have — exactly as it exists in their data centers — and deploying it onto Google Cloud Platform (GCP) or Amazon Web Services (AWS). Their conclusion: it’s too expensive and not worth the effort.

However, this is the wrong approach. Only by moving truly cloud-native applications — those that have been explicitly designed to use and optimize the new cloud technologies — to the public cloud can CSPs save significantly and gain real market advantages. This is what we have done at Optiva. We took core OSS/BSS, completely re-architected as cloud-native, and deployed on the public cloud. And our customers are reaping the benefits!

Provision what you need, when you need it

A key differentiator — and benefit — of public cloud is the capability to auto-scale both compute and database resources. With elastic computing and database resources, you no longer need to pre-purchase and plan resources to handle 20-40% above peak capacity. You can provision for actual capacity, scaling up or down as needed, to adapt to dynamic business needs. The resulting cost savings is significant and is only made possible by moving to the public cloud.

With this move, you eliminate a myriad of costs — from the obvious (like reduced hardware, data center, and third-party software) to human resources (like reduced database management staff). And as another benefit, your IT staff can focus on delivering business requirements and less on dealing with managing and troubleshooting hardware.

Take a holistic approach to TCO

The direct cost of a BSS application — the license and support fees — is a small part of the overall expense. It’s the tip of the iceberg, and there is so much more below the surface. The components that comprise total cost of ownership (TCO) of managing and operating an on-premise BSS deployment quickly add up.

It starts with the cost of purchasing and installing hardware. Then, there are the costs for hardware maintenance and support, which you replace every five years and need to repair and expand much more frequently. Next, there is the third-party software to enable the BSS application to run — from the operating system to the database management software and all monitoring, logging, security, and other solutions. Add to that support costs or annual subscriptions and network costs (switches, load balancers, etc.). Last, look at data center costs — rent, maintenance personnel, electricity, security, administration, and overhead of managing the operation.


What does this look like in practice?

We recently built a model for one of our customers — a medium-sized operator in Asia Pacific — and determined they would save 60% on their TCO over five years by moving their production and disaster recovery on-prem charging application to Optiva Charging Engine on GCP.

In addition to these dramatic cost savings, the operator also identified the following benefits:

  • Better preparing your technology stack for initiatives, such as IoT and 5G
  • Modern hardware and data center infrastructure managed by Google, not you
  • No need to maintain disaster recovery
  • Introduction of autoscaling
  • Zero-downtime, streamlined upgrades

With a compelling business case like this, it became an easy decision for this operator, and we’re implementing their new solution now.
