  • Better stability
  • Project quality has increased
  • New projects launched more quickly
  • Customer base growing and innovation hastening


Cardano’s mission is to maximize its customers’ investments through intelligent trade in equities, derivatives, foreign exchange, options and exotics. The company was founded in Rotterdam, in 2000, later opening an office in the UK. Between Rotterdam and London, Cardano has clients whose assets exceed 140 billion British pounds.

The group recently acquired NOW: Pensions Ltd, the group’s first venture in the retail pensions market. From managing a select portfolio of corporate clients, to becoming the third largest retail pension provider in the UK, the Cardano group is now preparing itself for rapid growth.


Founded in 2000, the Cardano group is a privately-owned, purpose-built risk and investment specialist, and a financial pioneer. It is widely recognized as a market leader in the provision of specialized services to private-sector and collective pension schemes in the United Kingdom and the Netherlands.

Charting the path toward containers

With a desire to expand Cardano’s leadership position in the pensions world, and aspirations to become a leader in the consumer pensions market, the technology team’s primary focus has been to transform the group’s IT infrastructure to keep pace. To maintain stability and keep innovating, while moving from 60 large clients to millions of individual customers, Cardano knew it had to scale dramatically.

Originally, Cardano’s .net and SQL-based infrastructure had been developed to suit the needs of its financial analysts — the code written for specific functions and requirements. Bespoke internal systems suited the group for a while, but the architecture couldn’t scale with Cardano’s growth. The team needed to migrate to a modern, web-based, scalable API (application programming interface) and microservices-centric architecture.

Containers have become an intrinsic part of the strategy since CTO Alison Johnston, and senior DevOps engineer David Sanftenberg, joined Cardano three years ago. With a shared history working in engineering at Goldman Sachs, they had experimented with containers and knew they wanted to bring an automated, scalable and container-centric approach to Cardano.

The team had a number of major challenges to contend with, including the building of new data web platforms. Consequently, the team wanted a way to onboard and manage Kubernetes in an intuitive way. With scarce resources, they needed a platform that would automate much of the difficult back-end processes and that would allow developers to get closer to the infrastructure.

Doing this, they knew they could free up vital time and expertise to focus on their major infrastructure projects. Looking at a number of Kubernetes distributions and orchestration platforms, most options lacked the right user interface (UI); then the team started working with SUSE Rancher.

“Everyone’s done the ‘hello world’ foray into containers, but when it actually comes to production and release, it’s a different beast. SUSE Rancher is a really nice solution that fills all the gaps that you discover when deploying containers to production.”

What were the problems Cardano was trying to solve?

Automation, resilience and efficiency

The automation of a host of basic functions has been one of the biggest reasons for bringing SUSE Rancher into Cardano. With two major development projects running concurrently, the team needed a stable platform that would automate several development processes and simplify the lifecycle: role-based access control (RBAC), Namespace-as-a-Service (NaaS), authentication, and Application Catalog, etc.

Historically, many basic tasks performed have been heavyweight in terms of manual operations and internal processes. The primary objective was to automate as much of the team’s daily business as possible — even major workloads running within business process management (BPM) platforms such as Camunda. Cardano’s portfolio management system, for example, is a node.js web app with node.js APIs. As Camunda works perfectly in containers, teams can access the platform via the API — view the portfolio, their current position, place orders and trade easily. Whereas this was always done with spreadsheets, teams can now use the container workflow which has dramatically reduced workload.

The team estimates its developers have saved 20-30 days’ support per quarter working with SUSE Rancher.


Importantly, Cardano’s portfolio management system is far more stable and reliable when running in SUSE Rancher. The team has found it easy to deploy multiple different tools and services easily, and at the same time, while maintaining overall stability. Historically, they would set up special servers for separate services, but this was time consuming and would slow down the development cycle. Moving to a containerized architecture in SUSE Rancher, the team can prototype and deploy Jupiter Hub, Rabbit MQ and a host of other solutions, simultaneously within the same platform while writing node js web apps and services.

Energy and environmental efficiencies

The flexibility of the platform has resulted in significant energy efficiencies, too. Running services in the cloud can result in significant costs if running an ‘always on’ model. By virtue of running SUSE Rancher in Azure, Sanftenberg has developed a script which allows them to power down certain services overnight. Any nonproduction workloads are off during the night but can be spun up again in minutes the next morning. As a result, the team have been able to reduce costs by over 75%.

Becoming a leader in retail

Earlier this year, Cardano took a major step toward becoming a leader in retail pension provision. With the acquisition of NOW: Pensions Ltd, the group has gone from managing a select portfolio of corporate clients, to becoming the third largest retail pension provider in the UK, with millions of individual customers. Not only is the sheer volume of customers dictating a shift to containers, it’s also a shift in portfolio development and provision, in line with market changes. A more tailored approach requires Cardano to manage millions of pension accounts directly. As NOW: Pensions integrates with Cardano’s infrastructure, SUSE Rancher brings the ability to scale at speed. Johnston and Sanftenberg can quickly spin up multiple instances of parallel servers — on demand and at no cost. This is particularly important at peak times (end of year statements); SUSE Rancher allows the team to scale the infrastructure up and down, as activity surges.

The cloud is important, too. Cardano wants to maintain an agnostic approach which can flex according to rapidly changing needs. The team sees the value of running SUSE Rancher in Azure, equally, the infrastructure has to be flexible enough to allow a blend of on-premises, hybrid private and public cloud, as needs change. This is critical for an organization that will become the custodian of millions of gigabits of sensitive data. SUSE Rancher brings an ability to scale clusters up and down, regardless of cloud preference.

‘Shift Left’ — empowering DevOps

Finally, a major driver in the move to SUSE Rancher was the desire to create a selfservice ecosystem for developers. With self-service becoming a major internal policy, Johnston and Sanftenberg’s key role is to empower developers to work autonomously. Working within the SUSE Rancher framework and UI, Cardano developers find it easy to set up a new service or a new environment. Unlike the old method, putting in a request and waiting for an infrastructure engineer to set up a server and install on their behalf, developers can come to the platform, build a container within SUSE Rancher and deploy it themselves.

Unlike the experiences of the past, where code is committed and runs somewhere in a remote location, SUSE Rancher has made the process of developing and committing code transparent through the lifecycle. Developers can see the code running in situ and retain control over its management. By allowing developers to get closer to systems, the team believes project quality has increased.

What’s next for Cardano?

Last year was about building platforms, this year is all about stabilizing and automating them. The team has invested heavily in new technologies, now it’s time to build controls around it. The ultimate aim is to provide developers with a way to push code without needing to log in to a terminal, or access SUSE Rancher. By putting a structured approval process in place, developers can deploy code with a few simple commands, further simplifying developments and accelerating innovation.

With the onboarding of NOW: Pensions, the team is now evaluating the integration of this completely different system — Java and AWS — with Cardano’s infrastructure. In particular, development teams on both sides are looking forward to experimenting with Istio — native in SUSE Rancher 2.3.
