Connect devices, analyze data, and automate processes with secure, scalable, and open edge-to-cloud solutions. A proximity placement group is an Azure Virtual Machine logical grouping capability that you can use to decrease the inter-VM network latency associated with your applications. Measure the network latency against the two DBMS VMs in the two DBMS zones that you selected. Each zone is composed of one or more datacenters equipped with independent power, cooling, and networking infrastructure. According to some tests, i can see like 600 microseconds (0.6 ms) latency between availability zones, inside the same region. Other common connectivity tools, such as Ping employ the Internet Control Message Protocol (ICMP), which can be treated differently from application traffic and whose results might not apply to workloads that use TCP and UDP. Consider starting with fewer iterations to test for success before running longer tests. Datacenter locations are selected by using rigorous vulnerability risk assessment criteria. Data traversing within or between regions is encrypted. In another doc explains what's regions. The ease of setup, configuration, and . Minimize disruption to your business with cost-effective backup and disaster recovery solutions. The output of this tool looks like this, and it is the Latency value were after: While running multiple tests on idle VMs, I found a discrepancy of ~20-30 us between tests, so take that into account when viewing the results below. When you use this architecture, you need to monitor the status closely and try to keep the active DBMS and SAP Central Services instances in the same zone as your deployed application layer. Each zone is composed of one or more datacenters equipped with independent power, cooling, and networking infrastructure. You usually look at two VMs that you want to cover with a failover framework. Select from a wide variety of Azure services, including zone-redundant storage (ZRS) to provide holistic resiliency in the event of a failure. Azure availability zonesare physically separate locations within each Azure region that are tolerant to local failures. Every Azure region each has at least three interconnected availability zones, with each zone consisting of one or more data centers. For example, heres a snipped of the metadata available for a VM with a specific Zone placement: //
