azure network latency between availability zonesazure network latency between availability zones

In the usual cases, it consists out of two VMs that are covered by a failover framework. The example specified the NetworkWatcher_eastus network watcher in a resource group named NetworkWatcherRG, but you can specify any existing network watcher. But in some Azure regions, the latency between the active DBMS VM and the SAP application instance, when deployed in different zones, might not be acceptable for SAP business processes. Nature of the SAP architecture is that, unless you configure it differently, users and batch jobs can be executed in the different application instances. Though some scenarios might work, other scenarios aren't yet working. The options vary depending on the selected Type. VM properties, such as Accelerated Networking or size changes. Compare the effects of changes in network latency after related changes are made to: Operating system (OS) or network stack software, including configuration changes. Ensure compliance using built-in cloud governance capabilities. We recommend that you use a configuration like this only in certain circumstances. It consists of discrete data centers housed in separate facilities, with redundant power, networking, and connectivity. Given this, you can expect an update of this table every 6 to 9 months outside of the addition of new regions. Deploy the VM SKU you want to use for your DBMS instance in all three zones. configure routing for Azure HLI. 1 Azure is available or coming soon to the following geographies: United States, Belgium, Brazil, Canada, Chile, Mexico, Azure Government, Asia Pacific, Australia, China, India, Indonesia, Japan, Korea, Malaysia, New Zealand, Taiwan, Austria, Denmark, Europe, Finland, France, Germany, Greece, Italy, Norway, Poland, Spain, Sweden, Switzerland, .

The larger the date range you specify, the more you can average latency over time. In another doc explains what's regions. Customer workloads can be categorized to utilize any of these architecture scenarios to meet application performance and durability. To achieve run time consistency for critical business processes, you can try to direct certain batch jobs and users to application instances that are in-zone with the active DBMS instance by using SAP batch server groups, SAP logon groups, or RFC groups. Azure availability zones are connected by a high-performance network with a round-trip latency of less than 2ms. An Azure Availability Zone is defined as: "Unique physical locations within a region. You don't need separate virtual networks for each zone. You don't need separate virtual networks and subnets for each zone. Other common connectivity tools, such as Ping, might measure latency, but their results might not represent the network traffic that's used in real workloads. Take advantage of high availability with Azure availability zones as a part of your comprehensive business continuity and disaster recovery strategy with built-in security and flexible, high-performance architecture. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. If, instead of specifying the relative latencies between a specific location and a specific Azure region using -Location, you wanted to determine the relative latencies to all Azure regions from a specific physical location, you can do that too. Eliminate any single point of failure through a regional network design that connects at least three physically distinct strategically placed datacenters in each region, taking into consideration more than 30 viability criteria and risk factors. I set out to test #1 within EastUS2. Azure regions where this type of deployment architecture across different zones could be preferable are: The basic layout of the architecture looks like this: Microsoft doesn't share any information about geographical distances between the facilities that host different Azure Availability Zones in an Azure region. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Azure Operator Nexus delivers operator mobile core and vRAN network functions securely in on-premises (far-edge, near-edge, core . Azure Arc Secure, develop, and operate infrastructure, apps, and Azure services anywhere Products AI + machine learning AI + machine learning Create the next generation of applications using artificial intelligence capabilities for any developer and any scenario More info about Internet Explorer and Microsoft Edge, how bandwidth is allocated to virtual machines. Just like Regions, Local Zones are fully managed and supported by AWS, giving you the elasticity, scalability, and security benefits of running on the AWS. Additionally, you can use it to help evaluate service providers' connections to Azure. Check the document Bandwidth Pricing Details. An Azure Availability Zone is defined as: "Unique physical locations within a region. The claim that there's always a network latency between 1 and 2 milliseconds isn't correct. Azure Availability Zones aren't available in all regions. For Listen on Interface (s), select wan1. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking". Based on many improvements deployed by Microsoft into the Azure regions to reduce network latency within an Azure Availability Zone, the new deployment guidance for zonal deployments, looks like: The difference to the recommendation given so far is that the database VMs in the two zones are no more a part of the proximity placement groups. Monthly latency numbers across Azure regions do not change regulary. Create reliable apps and functionalities at scale and bring them to market faster. Ideally, latency will be as close to zero as possible. Powered by, reference architecture described in the cloud adoption framework, Azure AD OAuth client credential flow with custom certificate walk-through, Allowing DNS resolution of Azure resources from on-premise, same v-net, same availability zone, same proximty placement group, multiple v-nets (in peering), same availability zone, multiple v-nets (in peering), across availability zones, multiple v-nets connected in a Hub & Spoke topology and Routing via. As a result, we're holding back documenting the usage of Virtual Machine Scale Sets with Flexible orchestration until some of the gaps are going to be closed. In the previous example, while it's clear that the latencies were the same both days and that there is a small difference between the latency of the two providers, it's also clear that the latencies for both providers are low on the 1-100 scale. You must specify a date within the past 30 days for -StartTime and -EndTime. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking". If you are interested in measuring the network latency from your end users to your selected set of network destinations you may want to try the Azure Internet Analyzer tool (preview). For an updated list, check your documentation for Azure services that support Availability Zones. The network watcher can be in any region. The network latency across Availability Zones isn't the same in all Azure regions. AWS builds Availability Zones 10km to 100km apart. You also want those VMs in an acceptable proximity to the DBMS layer to keep network latency in an acceptable window, SAP ASCS/SCS layer that is representing a single point of failure in the SAP NetWeaver and S/4HANA architecture. 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. In this scenario, the third-party will make a connection to your on-premises network. This allows architects to deploy their workloads in multiple DC's at the same time, but on the same network . Dependent on what you're willing to tolerate on run time differences other regions not listed could qualify as well. Evaluate service providers, or troubleshoot a user reporting an issue such as "the site was slow," from a specific location to the azure region where a service is deployed. Get fully managed, single tenancy supercomputers with high-performance storage and no data movement. Each zone is composed of one or more datacenters equipped with independent power, cooling, and networking infrastructure. Your workload will be spread out across . They can be configured in two ways. Availability Zones are connected through high-speed private fiber optic networks. AZs give customers the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.

Really, it all boils down to the Health Service and the Storage Bus Layer (SBL). Any available port number is fine. This deployment architecture is called active/active because you deploy your active SAP application servers across two or three zones. For example, you might use it when data can't leave the Azure region for security or compliance reasons. Determine whether you want to distribute your active SAP application layer across one, two, or all three zones, based on differences of network latency in-zone versus across zones. If an ASCS/SCS or DBMS VM fails over to the secondary zone, you might encounter higher network latency and with that a reduction of throughput. Based on your measurements and the availability of your VM SKUs in the Availability Zones, you need to make some decisions: In making these decisions, also take into account SAP's network latency recommendations, as documented in SAP note #1100926. As a result the deployment through the availability set isn't protected by power, cooling or networking issues that affect the dataceter(s) of the zone as a whole.
