This is actually the first publish within our Unpacking Office 365 series. You’ll find another posts within the series below:

Office 365 tenants share just one large logical infrastructure made up of thousands and thousands of servers spread across multiple Microsoft data centers. Figure 1-1 shows work 365 data center deployment at the begining of 2018. Because of its nature, this overview is incomplete as it doesn’t show a few of the infrastructure that’s under development.

Additionally, it doesn’t convey the deep investment designed to create “edge” network termination points setup by Microsoft to create user traffic rapidly into Office 365 from all across the globe or even the internal network that transports Office 365 tenant data between your data centers.

Microsoft organizes work 365 data centers into 14 regions. The information center region selected for hosting the information for brand new tenants is dependant on the nation (location) selected through the tenant. Because the launch of Office 365 this year, Microsoft has progressively built the Office 365 data center infrastructure using the aim of keeping data as local as you possibly can (“in-geo data residency”) to support customer choice and satisfy local rules.

Where Office 365 once concentrated service delivery from bigger data center regions for example The European Union (with data centers in Ireland, Finland, Austria, and also the Netherlands), localized services are available these days in individual countries like France, Germany, and also the U.K. This is also true in Asia-Off-shore, where Office 365 services originate from data centers in Japan, Columbia, Singapore, Australia, and China.

In addition to the capability to serve large customer populations, natural and economic advantages for example ambient temperature (to lessen the requirement for cooling) or accessibility to cheap hydro power influence data center placement. Clearly, security is of prime concern and Microsoft pays great focus on the physical security from the structures (you won’t find large signs proclaiming Office 365 or Microsoft anywhere) in addition to cybersecurity for that data contained inside the structures.

Since the Office 365 infrastructure is continually growing and expanding, the live place for tenant data also changes. Additionally, Microsoft moves data to rebalance strain on the servers in multiple data centers (inside the same region) and also to make more efficient utilization of available sources. Although the underlying infrastructure is altering constantly, users could work and access their information everywhere all over the world.

The Microsoft Cloud spans more than 100 data centers in 54 regions to provide service in 140 countries, but every data center doesn’t host Office 365. Following a new data center comes online, a classy migration process takes over to maneuver tenants using their company datacenters towards the new location.

This is also true when Microsoft results in a new Office 365 region. For example, following the Uk datacenters came online, some tenants requested to maneuver the work they do to individuals datacenters to have their data continued to be “in country” exactly the same happened in France or when Australian and Nz tenants gone to live in the Australian data centers.

The work happens behind the curtain (much like regular mailbox moves) so the eventual switchover is fast and painless. Microsoft has a documented process to assist tenants with specific data residency needs to inquire about Microsoft to maneuver their core data to a different region after it comes down online.

Additionally to work 365 applications, Microsoft has migrated over 400 million Outlook people that use the consumer email service in the legacy Hotmail.com infrastructure plan to run within Office 365. Outlook mailboxes are now using Exchange Online (the only difference may be the set of features uncovered to users).

These mailboxes run on a single server, storage, and network infrastructure as Exchange Online to benefit from features like Native Data Protection and Exchange Online Protection, and also the same client set can be obtained for services. Even though the same engineering teams can also be found for services, the functionality in Outlook far less comprehensive than that open to the entry-level Exchange Online plan.

However, the 2 services share some features (such as the approach to connect the Outlook mobile clients) and Microsoft introduces some functionality into one service before they choose to perform the same for that other. For instance, “Sweep” rules first made an appearance in Outlook and therefore are available these days in OWA, as the calendar and calendar discussing features available these days in Outlook originated from Exchange Online. Taken together, the infrastructure shared by Exchange On the internet and Outlook delivers email plan to over 600 million mailboxes.

Although Office 365 is invariability located alongside Azure, Microsoft doesn’t host other commercial work at work 365 data centers. Work 365 data centers indexed by Table 1-1 are individuals that provide core services (Exchange, SharePoint) in the present group of data center regions. Other services at work 365 suite, like Skype for Business and Project Online, may also run during these datacenters, however the picture is less obvious for applications like Planner, Teams, Sway, and Yammer.

In some instances, other datacenters inside the region deliver specific services, as with The United States in which the Sway and Planner services run from datacenters in California and Virginia. In other people, some services or backup for services originate from other regions. However, the problem changes with time so if you’re worried about data sovereignty, you can examine with Microsoft to know wherever your computer data are suitable for all relevant applications. Azure Active Directory is yet another service that come from another region. For example, the U.K. region uses Azure Active Directory running in EMEA datacenters.

Table 1-1: Office 365 data center regions

Microsoft intends to introduce Office 365 data centers in Nigeria (Gauteng and Cape Town), Europe, the Uae (Dubai and Abu Dhabi), and Norwegian, with services beginning within the 2018-19 period. They also have announced intends to switch the dedicated German sovereign data center region with a brand new data center region located in Berlin and Frankfurt to provide Office 365 services in 2020.

Development of a brand new data center region normally implies that Microsoft can provide customers the fundamental Office 365 workloads (Exchange On the internet and SharePoint Online) in the data centers. It will take a while prior to the full suite of abilities can be obtained, including applications (like Teams or Microsoft Planner) and utilities (such as the Office 365 Import Service). You’ll find more details concerning the current Office 365 data centers online.

Workloads Running Within Data Center Regions

Microsoft distributes work over the multiple data centers inside a region to safeguard data against failure. For example, the active-active the perception of Exchange Online Database Availability Groups (DAGs) implies that mailbox database copies appear in a minimum of two data centers inside a region. Additionally, as Microsoft adds data centers to some region, the chance exists to spread database copies to individuals data centers.

For instance, new DAGs designed for use by Exchange Online within the The European Union region may include databases spread over the Amsterdam, Dublin, Helsinki, and Vienna data centers. Distributing data across a lot of data centers cuts down on the risk that anyone outage will affect a significant quantity of users. It’s something which the typical on-premises administrator could never contemplate due to the investment required to build the underlying data centers and network.

One method to understand which data center region supports tenant information is to gain access to the business Profile with the Office 365 Admin Center. Visit the Data Location section and you’ll begin to see the region for many, although not all, from the workloads utilized by the tenant (Figure 1-2).

Figure 1-2: Data locations to have an Office 365 tenant

Although Azure Active Directory holds the majority of the information for tenant accounts and configurations within the same data center region like a tenant’s Office 365 data, the best exists for the reason that Microsoft stores five user-related attributes (such as the User Principal Name and password hash) for tenant accounts within the U.S. This really is to make certain that authentication can occur as rapidly as you possibly can wherever on the planet a person is situated. For additional info on this subject, see Microsoft’s support article around the situation for European customers.
