Why Amazon Web Services?
After considering many options, GAVDI Polska chose Amazon Web Services (AWS). The AWS platform is a leading provider of cloud solutions that assure results. Amazon Web Services also has a strong group of partners who help combine the functionality of SAP systems with modern cloud technologies.
By creating its environment in the AWS cloud, GAVDI trusted one of its long-term partners, SoftwareOne, to carry out the migration process and maintain SAP systems in the AWS infrastructure. As a result, GAVDI Polska can focus on its specialization, providing services and products for SAP HCM and SAP.
The GAVDI Polska systems are located on EC2 virtual machines (Amazon elastic Compute Cloud), which provide adequate computing power, memory size, and I / O operations performance for maintained systems. As additional projects are launched, virtual machines can be easily expanded, and the entire SAP application environment can be effectively duplicated and reconfigured. EBS (Amazon Elastic Block Store) volumes are connected to virtual machines to provide the best performance at a given moment and can be modified immediately to optimize performance as requirements vary.
S3 (Amazon Simple Storage Service) is used for back-up, ensuring durability at 99.999999999 per cent and storing backup copies in three separate locations at the same time. Additionally, AWS CloudFormation is used, which enables quick recovery of the environment in another AZ (Availability Zone) in the event of infrastructure failure. The Amazon Instance Scheduler is responsible for the periodic launch and shutdown of systems.
