  Publié: février 6, 2019, 7:40pm CET par Dave Bermingham

  A number of options are available for providing high availability protection for applications running in the Azure cloud. Some of these options are cloud-based services. Some are in the operating system or application software. And some are purpose-built by third-parties. The numerous permutations and combinations available can make it extraordinarily difficult to choose the best and most cost-effective solution for each application. In general, failover clusters are the best option for assuring high availability. Historically, failover clusters were relatively easy to configure and test in the enterprise datacenter using shared storage and standard features built into Windows Server.

Is there a way to make public cloud services equally, if not more, cost-effective than a high availability, high performance private cloud? Yes, but that requires carefully managing how the public cloud services are utilized by each application. The objective… [Continue Reading]
