Vodafone remote access re-platforming delivers flexibility-on-demand

Vodafone highlighted early successes in a major, ongoing re‑platforming exercise for desktop and application remote access, bringing a well‑timed enhancement of flexibility and functionality in the post-COVID‑19 environment.

The prescient refit, being run by Vodafone’s Group Data Centre (GDC) organisation, is seeing the operator shift to a “next-generation”, hybrid cloud‑based platform to support an estimated 100,000-plus users across Local Markets, Group functions, and external partners, said Michael Janssen, Lead Architect for Remote Access at GDC.

Through the project, which stems back to at least 2017, the Group is migrating away from a legacy Citrix-oriented solution to a blend of Microsoft Azure public cloud capability and an on‑premises stack from US hybrid multi-cloud infrastructure specialist Nutanix hosted in Vodafone’s European data centres.

Janssen said Vodafone’s workloads are “predominantly” being placed in the public cloud — to make use of flexible, on‑demand pricing — with the on‑premises infrastructure assigned to use‑cases with special legal requirements or particularly latency-sensitive. Nutanix plays the role of facilitating GDC’s “journey to a hybrid cloud scenario”.

Both public and hybrid cloud infrastructures were in place by mid-2019, along with accompanying network connectivity, and the new “foundation platform” is being tested by Local Markets as part of a “staggered migration” approach aimed at completing deployment in June 2021.

Big footprint

Overall, Janssen indicated that the new platform will support more than 6,000 applications and 55,000-plus concurrent users, spread principally across contact centres, retail stores, Local Markets, and Shared Services functions within the Group’s Vodafone Intelligent Solutions (_VOIS) arm. Around 60% of users are said to be internal within Vodafone, with the remainder customer-facing partners and other contractors.

The platform does not extend to African operations, which are not yet using GDC functionality, but the unit is discussing with them their “journey for remote working”, said Janssen. He added that the new infrastructure will support usage from outside the Group’s Europe Region, such as _VOIS facilities in Egypt and India, and Vodafone Spain’s contact centres in South America. “Basically, we are hosting a platform of the European market, but access is coming from across the globe”, he said.

One step ahead of pandemic

Janssen said the pandemic, and the accompanying uplift in demand for remote access, had not made GDC’s “migration life easier”, but the new, more flexible platform had enabled Vodafone’s business to run more smoothly where instances were available. “There were additional requirements in virtual desktops, in virtual applications, where we could help quite fast in racking up instances”, he said. If there was leftover capacity on‑premises at peak times then that could be used, and in the markets where the migration had already kicked off, we could directly make use of public cloud instances”.

Vodafone UK is said be one of the more advanced Local Markets in terms of integration and validation, with its contact centre operation having already migrated to the new platform before the country entered its first pandemic lockdown in March 2020. This enabled GDC to “within a few hours” ramp up capacity to serve 2,000 retail store employees that needed remote access, enabling them to keep working. “That was a huge success already for the new architecture”, said Janssen. He praised both Nutanix and Microsoft for dealing with the “dramatic spike in infrastructure requirements” seen in the early days of the pandemic.

Hybrid cloud for hybrid offices

Following the crisis, Vodafone Group Chief Executive Nick Read has indicated interest in a “hybrid” office future, with new ways-of-working being piloted in the UK, Czech Republic, and Hungary, and Janssen stressed that, having migrated to the cloud, the Group’s IT stack is better configured for a more malleable approach.

“ We all know remote working will remain in the future. There are markets that have already decided that a higher number of jobs and users should continue to work from home [after the pandemic] and it helps that we have this dynamic opportunity with the remote access platform. We can easily scale up and scale down for whatever the business is demanding in the near term. ”

Another effect of the pandemic, with the emphasis it has placed on ensuring business continuity, could be that Vodafone pushes the button on a move to desktop-as-a-service solutions. “We have in the industry talked about desktop-as-a-service for quite a while — more than a decade now… I think the COVID‑19 situation finally made desktop-as-a-service here to stay and now all the vendors have their offering”, said Janssen. “That is something that we are looking at for Vodafone”. Microsoft and Nutanix are both contenders in this market segment, along with the likes of Amazon Web Services.
