While the cloud can offer an organization a wide array of benefits—including a reduction in infrastructure costs, greater flexibility to deploy regionally, and more—it’s not always an organization’s first choice when it comes to building out an SAP landscape, where high availability (HA) is essential.
A cloud service provider such as AWS may offer a service level agreement (SLA) that guarantees that at least one VM in a HA failover cluster will be available 99.99% of the time, but the availability of a single VM does not translate to 99.99% availability of this mission-critical application.
