Epos Now is a cloud-based software provider, specialising in the
design and manufacture of electronic point of sale systems and
integrated payments solutions.
Kloia modernized Epos Now’s application environment on AWS.
We moved Windows environments to Linux and .NET Core, and
started using Amazon EKS, AWS Lambda, and Amazon API
Gateway to efficiently manage and scale their internal and
customer-facing application.
Aside from the obvious benefits of modernization, Epos Now
gained incredible speed in software delivery. They can now roll
out features every day instead of every three weeks.

GoDataFeed is used by thousands of brands, retailers, and agencies
to transform static catalogs into dynamic product feeds tailored to
channel requirements and optimized for marketing goals.
Kloia has rearchitected and replatformed GoDataFeed for
cloud-native success. We started with a deep-dive workshop with
the team who designed, built, and currently manage the platform at
GoDataFeed. We then implemented a cloud-native architecture
within a six-month timeframe.
By converting monolithic legacy applications from the .NET
Framework into cloud-native, GoDataFeed benefitted from the
agility, scalability, and cost savings of the cloud.

Digiturk, Bein Media Group Company, is a global sports and
entertainment media group and their services include both streaming
and VoD (Video-on-Demand), along with value-added services that
includes complex business logic developed over the last two
decades.
Kloia has rearchitected and replatformed beIN for cloud-native
success. We started with a deep-dive set of workshop with the team
who designed, built, and currently manage the platform at beIN. We
then modernized their Microsoft Workloads together with splitting the
Monolith to the Microservices within a one-year timeframe.
By converting monolithic legacy applications from the .NET
Framework into cloud-native, beIN benefitted from the agility,
scalability, and cost savings (65%) of the cloud.
