Telliris Transitions to Google Cloud Platform for Enhanced Scalability and Performance

Telliris, a leading provider of IVR solutions for workforce management and time & attendance celebrates its transition to the Google Cloud Platform (GCP) for Telliris Attend in Cloud format.

Telliris Attend was first made available in Cloud format in 2007 and has always been available in On-Premises licensed format since its inception in 2003. Unlike most enterprise software solutions which once transitioned to cloud no longer offer an on-premises version, Telliris is available in both Cloud SaaS as well as On-Premises formats. This is due to it serving a telecommunications role where on-premises format is sometimes more favorable, keeping traffic within an organizations private network and not using the public telephone network.

The transition occurred one year ago and there’s not been a single hiccup. Prior to GCP Telliris in cloud format was provisioned in carrier-neutral data centers also called carrier hotels. Unlike traditional data centers, carrier hotels offer the most interconnected facilities which provide significant benefit from a telecom perspective.

Provisioning at a public cloud provider was made possible when the telecommunications industry transitioned call transport from Time Division Multiplex (TDM) to Voice over IP (VoIP).

The Google Public Cloud enabled Telliris to provision a High Availability, Active-Active environment with multiple levels of fault resilience. An entire facility can go off-line with no impact whatsoever. Scalability enables 100% full load handling even if an entire GCP region were to go off-line. The ability to handle full load under any condition is similar to aircraft design, if a multi-engine aircraft loses all power on an engine, safe operation is still assured due to sufficient remaining available power.

Call processing on the public telephone network (PTN) is handled by Verizon, the world’s second largest telecom provider. Connectivity is maintained between each Telliris GCP region and three geographically dispersed Verizon telecommunications end-points. Each end-point has two connections to each GCP region. This provides a very high level of telecom fault tolerance.

By using an Active-Active architecture across both Google and Verizon an exceptional level of high reliability and high efficiency is achieved. This was simply not possible a short time ago.

Telliris uses a common code base. The same exact software is used for on-premises and cloud format. Those familiar with Telliris are aware they can quickly provision using a one-step installation process which takes 15 minutes to perform. The same quick installation holds true in the cloud – in fact current users can migrate their on-premises Telliris to their own Google Cloud Platform without the need for assistance from Telliris. The ability for end-customers to provision their Telliris solution using Google Cloud Platform was announced in May of 2019. As the saying goes “do they eat their own dog food” – The answer is wholeheartedly “yes” – Celebrating the one year anniversary for Telliris in cloud format at Google with 100% success.

Performance testing included high capacity operation with fifteen Telliris nodes processing at 120% of maximum rated capacity. An example test cycle, a five hour test with 15 nodes running 300 concurrent calls each, processed over 2.5 million transactions. This test is substantially more demanding than normal production usage which commonly peaks for short durations at the top of the hour. This testing has been performed for over 4 years.
