Cerillion originally came to 4D for support on a project for a new customer which required high levels of resiliency across two data centres. Today, 4D provides Cerillion with hosting across two data centres, networking between the facilities, layer-2 and layer-3 transit and managed backup services. The two companies regularly work together on new projects, with 4D acting as a consultant to provide advice and support as Cerillion continues to grow.

Despite the challenges of lockdown, working with 4D we were able to setup a geo resilient hardware stack in record time. The data centre interconnects and internet services worked first time, meaning minimal site visits were required, and 4D’s tech support and onsite smart hands were very quick to respond to any issues.”

The Challenge

Cerillion needed a network with high levels of resiliency – including multiple network paths through the data centre, across the core network, and out to the wider internet. We handled everything network-related which let Cerillion avoid the added complication of third parties getting involved. They also needed a variety of services hosted across a dual-site system. Since 4D could provide these dual-site services, and operate as an ISP for their network infrastructure, working with us meant Cerillion could achieve everything they needed with a single managed infrastructure partner, without diverting focus from developing their platform and end customers.

It is always great to work with a SaaS business that has such a keen eye on resiliency. When you couple that with Cerillion’s innovative software offering, they provide a reliable and valuable service.”
