As a SIOS Strategic Alliance Partner, Amazon has worked closely with SIOS to ensure our SANLess cluster solutions are fully integrated with Amazon Web Services. SIOS DataKeeper enables you to create a SANLess cluster using local storage in an Amazon cloud environment. It keeps real-time copies of that local storage synchronized across Amazon EC2 Availability Zones using a lightweight, host-based replication that minimizes the performance impact on application servers and networks. This proven, highly efficient solution for AWS deployments is designed to protect your applications and data from downtime and disasters while lowering your total cost of ownership. SIOS SANLess clusters also ensure security of your cloud environment by controlling access to the backup environment, preventing unauthorized or inadvertent update access, and protecting against data corruption.
