Microsoft is finally<\/em> making updates to Azure to reduce downtime to virtual machines when a host is rebooted.<\/p>\n

Microsoft sent out the following announcement via the regular pricing and features update email to customers last night:<\/p>\n

That sounds like Quick Migration. So Azure has caught up with Windows Server 2008 Hyper-V. \"Winking And it sounds like later in 2016, we\u2019ll get Live Migration … yay \u2026 Windows Server 2008 R2 Hyper-V \"Smile<\/p>\n

Seriously, though, Azure was never designed for the kinds of high availability that we put into an on-premises Hyper-V cluster. Azure is cloud scale, with over 1 million physical hosts. A cluster has around 1000 hosts! When you build at that scale, HA is done in a different way. You encourage customers to design for an army of ants \u2026 lots of small deployments where HA is done using software design leveraging cloud fabric features, rather than by hardware. But, when you have customers (from small to huge) who have lots of legacy applications (e.g. file server) that cannot be clustered in Azure without redesign\/re-deployment\/expense, then you start losing customers.<\/p>\n

So Microsoft needed to make changes that acknowledged that many customer workloads are not cloud ready \u2026 and to be honest, most of the prospects I\u2019ve encountered where code was being written, the developers weren\u2019t cloud ready either \u2013 they are sticking to the one DB server and one web server model that has plagued businesses since the 1990s.<\/p>\n

These improvements are great news \u2026 and they\u2019re just the tip of last night\u2019s very big and busy iceberg.<\/p>\n
