Data residency challenge solved with a new cloud platform, multi-cloud application deployments and ongoing cloud engineering support.

CASE STUDY - Delio

Delio Logo

Delio, a fintech scale-up, needed to enable faster, more reliable software development. The plan was to migrate from the legacy virtual instances to AWS EKS and evolve the monolithic core application into a microservices architecture. DevOpsGroup made the transition quick, easy and effective with a containerisation approach. This rapid modernisation has advanced Delio’s capabilities, giving it the confidence to engage with larger financial companies.

Fintech overcomes data residency issues with multi-cloud presence

New opportunities in Switzerland meant Delio needed to store customer data on Swiss soil, but its existing cloud vendor didn’t have a presence there. DevOpsGroup was appointed to help build and run a dedicated platform hosted on Azure’s Swiss datacentre.

The data residency challenge

When Delio secured a high-profile Swiss investment bank as a client, a rethink of its cloud computing model was required. While all customer information had to be held in Switzerland, Delio’s existing cloud vendor, AWS, didn’t have a data centre in the country. To overcome this issue, Delio opted to build a dedicated platform on Azure for its new customer and the broader Swiss market while retaining its AWS-hosted platform for other markets.

DevOpsGroup was appointed to help build a new solution in Azure to support Delio’s core application. This involved providing a way to deploy services to both cloud platforms. There were also long-term technical matters to consider beyond the initial set-up and data transfer. Delio’s in-house skillset centred on AWS, meaning neither developers nor DevOps engineers had experience of Azure. This presented potential issues surrounding the compatibility of new software updates and the maintenance of reliable and secure operations.

Since DevOpsGroup holds expertise in both AWS and Azure, we were the ideal partner to overcome these issues with a cloud platform operations service.

“We wanted an IT partner with advanced cloud engineering expertise across both AWS and Azure. DevOpsGroup had the skills we needed to build a strong, secure and compliant presence in Switzerland.”

Build it, migrate it and run it

We replicated Delio’s AWS environment during the platform build phase, working with the Delio team to make improvements and changes where required. This included adding more automation, enabling Delio to add new Swiss customers and scale seamlessly over time.

Any cloud-to-cloud transition presents challenges related to code incompatibility between the two providers. This was a particular issue for Delio as the development team continued to write code during the setup phase.

Services in AWS and Azure may have the same purpose, but they work very differently. When it comes to storage, AWS has S3 buckets, whereas Azure has storage accounts. Authentication methods differ between platforms, too; the APIs the service needs to interact with are different, as are the configuration and parameters required to retrieve data. We ensured Delio’s developers benefited from an increased understanding of different software development kits (SDKs) and updated applications to work on each platform.

We also configured application deployments to be tagged according to the destination cloud platform. This allows different configurations (such as API endpoints, connection strings, credentials) to be retrieved, meaning an application can reach out to the appropriate storage resources.

Consistency and operational maturity

With DevOpsGroup’s assistance, Delio now has a fully operational multi-home platform, enabling it to meet the demands of the Swiss private banking market seamlessly and securely. In-house developers can easily deploy to the AWS and Azure-hosted platforms, ensuring a consistent approach to ongoing innovation and improvement.

“DevOpsGroup is a great cloud-based operations partner for us. Not only are they always on-hand to offer technical guidance, but they've taken the time to help upskill our team with Azure's best practices and techniques. This partnership has enabled us to access important new markets, and we've been able to build a fantastic working relationship with the DevOpsGroup engineers.”
