Colt Data Centre Services has been designing, building and operating large-scale data centres and providing data centre colocation services for more than 15 years. However, they were having problems with their core database, as it was struggling to keep up with the company's growth. Colt selected DSP to migrate their database to OCI whilst keeping it connected to Azure, as we are experts in Oracle and Microsoft multicloud services.

"The solution was blazing fast. It felt like the Oracle Database was sitting right next to the VMs in Azure."

The Challenge

The global IT infrastructure manager for Colt Data Centre Services,  saw its core database struggling to keep up with the company’s growth. Based in London, Colt has 26 state-of-the-art facilities in Europe and Asia-Pacific. These massive hyperscale data centres power their customers’ surging data and computing needs.

Colt was running its Oracle Database 19c on a couple of Microsoft Azure virtual machines. “Hosting an Oracle Database on an infrastructure that isn’t tailored to the purpose held us back,” says their IT infrastructure manager. “Our platform couldn’t keep pace with our business expansion. We also incurred high costs in hosting and support, with my team constantly trying to hotfix our solution.”

Finding a better alternative was an urgent priority. “The database hosts everything we do,” says their IT infrastructure manager, “including customer data and billing. It helps us run the business and makes sure the money flows.”

The Solution

To improve performance, Colt needed a completely native solution, one that ran its Oracle Database on Oracle Cloud Infrastructure (OCI). When Oracle announced its Interconnect partnership with Microsoft, Colt jumped at the opportunity. Built on a private, direct connection—a kind of high-speed “express lane”—Interconnect lets businesses migrate workloads and seamlessly run them across Azure and Oracle Cloud. The company could migrate its database to OCI and keep it connected to Azure. “The speed of deployment, easy configuration, and trust in both companies cemented the decision,” says Colt's IT infrastructure manager.

Working with DSP, Colt planned a six-month implementation. It took only two months, however, giving Colt’s team extra time to tweak the solution.

When they unveiled it, the solution was extremely fast, with OCI-Azure latency as low as 1.1 milliseconds. Two Azure virtual machines still form the front end of Colt’s platform, sending mega-workloads to OCI via Interconnect’s pipeline.

The Result

The solution has been rock-solid, with zero outages. It’s also been cost-effective, yielding savings of about 15% compared to the old setup. Using OCI’s CapEx model, Colt expects the savings to double in the next year.

Built-in OCI security helps Colt comply with extensive industry regulations. And as a managed service, Interconnect comes with Oracle technical support.

Added Value

Ongoing Support

As a managed service, Interconnect provides Oracle technical support, and manages major incidents and alerts. DSP works in collaboration with Colt's internal support team.

Performance Boost

The new solution has increased performance levels and is extremely fast, with OCI-Azure latency as low as 1.1 milliseconds, meaning Colt's databases can now keep up with the company's growth.

Cost Reduction

DSP's solution was successful, resulting in significant cost savings. It saved Colt about 15% compared to their previous setup. They can now use those savings to invest in other areas of the business.
