Theoretically, the cloud seems tailor-made for ensuring high availability (HA) and disaster recovery (DR) solutions in mission critical SQL Server deployments. Azure, AWS, and Google have distributed, state-of-the-art data centers throughout the world. They offer a variety of SLAs that can guarantee virtual machine (VM) availability levels of 99.95% and higher.

But deploying SQL Server for HA or DR has always posed a challenge that goes beyond geographic dispersion of data centers and deep levels of hardware redundancy. Configuring your SQL Server for HA or DR involves building a Windows Server Failover Cluster (WSFC) that ensures not only the availability of different machines running SQL Server itself but also — and most importantly — the availability of storage holding the data in which SQL Server is interacting.

In the pursuit of data protection, businesses nowadays face more hurdles in the security landscape than ever before. We know there’s a growing demand for reliable, scalable infrastructure, but issues with downtime are complicating businesses’ confidence in their existing systems, implicating all-too-precious data in the process.

For example, 31 percent of respondents in the 2018 Data Center Industry Survey experienced severe and damaging downtime, and almost 80 percent note that the downtime they did experience could have been avoided. Not to mention, prior to IoT, organizations had to protect their datacenter and ROBO locations. With the emergence of IoT, organizations need to protect their infrastructures at the edge and ensure reliability beyond the core of their datacenter alone.
