Delaware North is a major food and hospitality company serving half a billion customers each year.

“We compared the costs of keeping our on-premises data center versus moving to the AWS cloud…We estimate that moving to AWS will save us at least $3.5 million over five years by reducing our server hardware by more than 90%. But the cost savings will likely be greater due to additional benefits, like the increased compute capacity we can get using AWS. That lets us continually add more and larger workloads than we could using a traditional data center infrastructure, and achieve savings by only paying for what we use.”

Playwith is a Korean online game developer and publisher that publishes high quality, free-to-play games.

“We chose to run our Windows workloads on EC2 AWS because the platform provided us with scalability and performance, versus other cloud providers that we were evaluating. We recently launched our first mobile game using our own IP, which mean that it was very difficult to predict the number of initial users. During the launch, it was important that we could prepare for unexpected user traffic overflow. In the past, we had to manage every single thing in an internet data center environment, even physically visiting the datacenter. But now that we’re on AWS, we can focus on our core business better instead of managing a datacenter. We would have needed 1.5x larger of a workforce to successfully manage an infrastructure this large. On AWS, we are able to manage large-scale infrastructure with a compact workforce.”

Trimble offers software, hardware and services to help customers in agriculture, construction, geospatial, and other industries to blend physical and digital businesses.

"Migrating our Windows-based application to AWS has resulted in close to 100% uptime on a system that is significantly easier to scale. As soon as we did the migration and we completed the reservations on these instances, we were able to save about 23% cost based on what we were spending on drag space. And after enabling scheduled scaling methodologies where the development instances don't run all the time and the production instances run only UK working hours, Trimble is easily able to see about 35% savings.”

Xero provides cloud-based accounting software to small and medium-sized businesses, with over two million subscribers worldwide.

“Running Windows on AWS was a key enabler in our move to AWS in 2015. CloudFormation allowed us to reimagine our existing manual deployment processes entirely in code. More recently AWS System Manager made it even easier to run script for patching in a controlled manner across portions of our Windows fleet. Finally, the stability of the EC2 platform when combined with Autoscaling groups gives us peace of mind around tolerating Availability Zone failure without missing a beat. This allows our teams to focus on improving the application or in some cases transitioning part of the stack to containers. Over the next 3 years, Xero plans to move from a 70% Windows / 30% Linux mix to a 30% Windows / 70% Linux mix of OS. The flexibility of the AWS Platform has been a key enabler in this change.”

Ben Salt, Executive GM of Reliability, Xero

IntelliGuard creates Radio Frequency Identification (RFID) solutions that offer automation for management of pharmaceutical inventory and critical care supplies.

"When I first came to IntelliGuard, I saw what we had built in Azure and, knowing what I knew about AWS, felt it was only right to advocate that we move to AWS. I feel AWS is much more mature than Azure. It was the obvious choice. We must make it easy for our developers to deploy into an infrastructure, create solutions, and iterate. When we ran in Azure, I didn't see those capabilities for our team. For example, the Azure SQL database solution didn't have much of the functionality we wanted to take advantage of, even though SQL is a Microsoft product. Comparatively, Amazon Relational Database Service (Amazon RDS) for SQL Server provided us all of the flexibility and functionality we needed and more."

Jeff Webber, Director of Technology, IntelliGuard
