A Verizon Wireless
success story

Verizon Wireless deploys Akka and doubles overall business and performance results using half the hardware

The need

More than a decade ago, Verizon adopted a commerce platform from Oracle to process business transactions and orders from customers online. Demands on this system were exploding as Verizon moved more and more customer transactions online and added support for a range of new features, including Alexa, Google Home, Facebook chat bots and more.

Due to the complexities of the system architecture, it took the Verizon team on average two months to roll out any new features on this legacy platform—hindering business agility.

The challenge

The existing platform was a huge monolith, and since the code base was so large, software builds often took a whole night to run. Setting up a testing, development or production environment required five to 10 days of work, and deploying an emergency fix to production took 24 hours.

Even worse, the legacy platform couldn’t handle the massive increase in site traffic on holiday sales days and other big events, such as the launch of a new iPhone. So, for more than a decade, Verizon’s engineers had to recreate the entire e-commerce site in parallel with a special light code base that disabled logging, removed all complex transaction requirements, and was subjected to massive load testing. This bespoke website only ran in production for a few days each year, even though it took more than six months to create.

Verizon’s site never crashed on the holidays or after a new iPhone launch, an industry record unmatched by any other cell provider. But all of that special code was tossed out every year and never re-used.

The solution

Verizon set up a special team of architects to review alternatives to the Oracle platform. They quickly embraced reactive principles, and over a two-month period, they evaluated every major platform on the market. The final two choices were Spring Boot from Pivotal and Akka.

What Verizon liked about Akka is its ability to scale as needed, its hot reload features, and the ease of use it provides for ops teams. Akka also delivered blazing performance through its support for stateless, asynchronous non-blocking I/O, the ability to bounce a server in seconds, minimal garbage collection, and a hot reload capability that cuts development cycles in half.

Moreover, compared to the legacy Oracle system, which required 20GB of reserved memory since everything was cached locally, Akka only required a Java Virtual Machine (JVM) footprint of under 500MB—making it considerably more memory-efficient.

The results

Verizon quickly built out a new system for both the Verizon app and the mobile platform, and the before and after results were stunning.

In the mobile phone network industry, average customer response times through the website are around six to seven seconds. With its legacy platform, Verizon was at six seconds. With Akka, that time was slashed to 2.4 seconds. The legacy platform could handle up to 1,600 orders a minute. Akka has been tested to 12,000 orders per minute and Verizon expects to increase that number over time—an improvement of almost an order of magnitude.

The performance and user experience benefits have translated into amazing bottom line business results. Sales on the new platform increased 235 percent; conversion rates jumped 197 percent; builds took 40 percent less effort; and total cost of ownership (TCO) was cut in half.

By halving its resource requirements on both the hardware and human side of the equation, Verizon Wireless achieved results that are twice as good as with the previous platform. The CIO is now taking the new system to other major business groups at Verizon, such as billing and point of sale, to encourage them to move to Akka.
