Provision local DNS servers in each location and ensure that Microsoft 365 connections egress to the Internet as close as possible to the user's location. Remote users connect to corporate resources both in on-premises datacenters and in the cloud from uncontrolled locations such as homes, hotels, and coffee shops. These network hairpins greatly lengthen the network path between a user and Microsoft’s global network, and this increases network latency and reduces performance of Office 365. Recommended optimizations can be applied the same way to all endpoints in a given category. Most small businesses are going to use either a PAN, LAN, WAN, or VPN for their network infrastructure. Most enterprise networks enforce network security for Internet traffic using technologies like proxies, SSL inspection, packet inspection, and data loss prevention systems. However, existing internet connectivity will not provide adequate performance for Office 365 in most scenarios. When Internet services and web sites are distributed around the globe, latency between corporate egress points and any given destination endpoint is largely a function of geographical distance. The optimum connectivity model is to always provide network egress at the user's location, regardless of whether this is on the corporate network or remote locations such as home, hotels, coffee shops and airports. But it’s not always simple like that. All endpoints are hosted in Microsoft datacenters. However, this reduces the number of clear frequencies an AP can use against neighbouring APs. You can get the best possible performance by following a few key principles: For more information on Microsoft 365 network connectivity principles, see Microsoft 365 Network Connectivity Principles. For more information on understanding and applying Microsoft 365 network connectivity principles, see Microsoft 365 Network Connectivity Principles. For example if it’s a sales office they may communicate with the Head office just through email or phone. You can learn more about the Microsoft Global Network at How Microsoft builds its fast and reliable global network. This all too often neglected part of your infrastructure usually is the weakest link and is the cause of most system outages when not managed properly. A holistic approach to enhanced security should include consideration of the following: For more information on Microsoft 365 security and compliance, see the articles Microsoft 365 security and Microsoft 365 compliance. Examples of Optimize endpoints include https://outlook.office365.com, https://.sharepoint.com, and https://-my.sharepoint.com. As organizations adopt Microsoft 365, some network services and data are partly or completely migrated to the cloud. The following are common examples of network infrastructure. Microsoft recommends the following principles to achieve optimal Microsoft 365 connectivity and performance. The diagram below shows an example of a network topology that allows users connecting from main office, branch office, and remote locations to follow the shortest route to the closest Microsoft 365 entry point. Because Microsoft 365 runs on the Microsoft Global Network, which includes front-end servers around the world, there will often be a front-end server close to the user's location. In the majority of cases, the best user experience is achieved by allowing the customer network to route user requests to the closest Microsoft 365 service entry point, rather than connecting to Microsoft 365 through an egress point in a central location or region. Securing Microsoft 365 connections The goal of traditional network security is to harden the corporate network perimeter against intrusion and malicious exploits. A supervisory position responsible for a team of network infrastructure staff who provide monitoring, troubleshooting, and maintenance of networks and communications of moderate complexity in assigned organizational areas. By treating Microsoft 365 connections as trusted traffic, you can prevent latency from being introduced by packet inspection and competition for proxy bandwidth. The diagram below illustrates such a network topology. To ensure that Microsoft 365 connectivity is not subject to network hairpins even in the local egress case, check whether the ISP that is used to provide Internet egress for the user location has a direct peering relationship with the Microsoft Global Network in close proximity to that location. Endpoints may be URLs, IP addresses or IP ranges, and some endpoints are listed with specific TCP/UDP ports. The local egress network architecture does this by allowing Microsoft 365 traffic to be routed over the nearest egress, regardless of user location. Today Office Network Cable Installation Service File,Data Sharing Network For Office 09 694512438,09 951846759 New categories of network endpoints to differentiate highly critical network traffic from network traffic which is not impacted by Internet latencies. Without optimization, traffic between users and SaaS applications is subject to latency introduced by packet inspection, network hairpins, inadvertent connections to geographically distant endpoints and other factors. Before you begin planning your network for Microsoft 365 network connectivity, it is important to understand the connectivity principles for securely managing Microsoft 365 traffic and getting the best possible performance. Mentors network infrastructure and operations staff. You'll get a score based on how aligned you are with best security practices.
