After evaluating on premises and cloud options, the company decided to go for Amazon Web Services (AWS) cloud with Runibex who was its partner for their implementation of their SAP platform. Enhanced SAP performance, a fully structured and operative disaster recovery scenario, and reduced storage costs were the main targets at first stage. A cost model was developed and main saving points determined. Furthermore, a seamless and swift migration goal kept in mind, a total of 72 hours of migration time was programmed and realised.

Amazon Simple Storage Services (Amazon S3) for data backups and AWS Elastic Block Store (AWS EBS) SSD volumes as storage are used. Amazon Virtual Private Cloud (Amazon VPC), and AWS Identity and Access Management (AWS IAM) is used for user and access management.
