Join David Elfassy for an in-depth discussion in this video Bandwidth requirements for Office 365, part of Office 365: Deployment.
- [Instructor] A common question that I receive when organizations plan to deploy or migrate to Office 365 is how much bandwidth do I really need to connect to Office 365? Many organizations will come from an environment where they have on-premises servers. That is, their servers are located in their local data centers, and they have high speed reliable connections to those email servers. Now moving to Office 365 means that you are going to be moving your email services to the cloud, over to the internet, and you will be depending on a connectivity and a connection to the internet.
How much bandwidth does that connection require, and how much access do I need to have to these Office 365 services? If I have various appliances on my infrastructure and these appliances need to have dedicated bandwidth to Office 365, how much of that bandwidth is really required? Now, that need and those requirements become more and more critical as we have more services that run in Office 365. If you can see here from my environment, I'm running Exchange, OneDrive, SharePoint, Skype for business, and Yammer.
These are various services that I have available for my Office 365 deployment. Now, these services all have various bandwidth requirements based on the numbers of users that I have, and based on the amount of connections that these users require to Office 365. So in order to calculate those bandwidth requirements, I'm going to need some calculators. And Microsoft provides these calculators in the form of spreadsheets. You have separate bandwidth calculators for separate products.
So this is an example of an Exchange bandwidth calculator. All the other calculators are found on the Office 365 websites. Now the first thing I want to point out is when I'm looking at this Office 365 calculator, and I look at the version changes, I see that the last time that this was updated was in 2012. Now, this is the latest one, as of 2016 right now, but unfortunately, it is quite old. Fortunately though, many of those numbers have not changed.
The amount of bandwidth that is used by most of these network clients has not changed a lot. So I'll just give you a quick previewing of where and how this calculator works. So the first tab that you have here is the input tab, which actually gives you an evaluation of how much size or how many changes you perform, or the amount of services that you have on your network. What is being used on the network? So I have this information here. Then I have my profile, my user profiles. I have four of them. From light to very heavy.
Light means it's a user that has small messages, that doesn't connect a tremendous amount, that has a smaller sized mailbox, and that doesn't have a tremendous amount of daily emails that he's going through. A very heavy user is a user that has a lot of daily emails, that has a lot of constant synchronization, and that sends and receives a tremendous amount of email messages. Now what a heavy profile is for one organization may be different than for another organization, so these numbers can be updated and tweaked along.
And as you modify these numbers, they will impact the numbers on the following tabs, which is here, you specify how many offices you have, how many, the profiles of the users that you have, the time zones, so that you can evaluate the connections of these users. As well, you can specify which clients are they using. Are they using a mobile phone, are they using a web client, are they using varying versions of Outlook? Now, based on that, I will start to get some predictions over the bandwidth that is being used.
And that's because if I have a mobile phone client, as opposed to an Outlook client, they'd be using a different type of connection, and therefore would be using different types of bandwidth. Under my data table, I see the average amount of kilobytes used by various types of clients, and you see the difference here between MAPI and cached, as opposed to Outlook Anywhere and cached, so this is an https connection, for example. So looking at those will be helpful as well.
Now, note that these numbers have changed in the latest version of Outlook. Right now, we're at Outlook 2016, and the connections now no longer support MAPI, for example, so Outlook has changed, and these numbers will need to be updated. You'll have to look on the Microsoft Website for the latest numbers. They are not yet available for Outlook 2016, but I suspect that they will be available very soon. So the same way that we have this calculator for Exchange, we have a calculator for SharePoint, and a calculator for Skype or Link, as it's still named in the calculator name.
And these calculators will help you evaluate the amount of bandwidth. Now, this is not an exact science. You will get a rough number of how much bandwidth is being used. Now, if you feel or if you're worried that this bandwidth will not be enough, I recommend that you look at something called Express Route. So Express Route for Office 365 is supported by certain carriers, so you'll have to go on the Express Route for Office 365 website from Microsoft, and by using Express Route, you will create a dedicated connection to Office 365 through your internet provider.
And this, Microsoft describes it as essentially having Office 365 on your internal network, that's how powerful and how fast it is. You need to verify that your internet provider is one of those supported by Microsoft. If you are using your country's major providers, they are supported by Microsoft, and basically, what Microsoft does, is that they provide high speed links from those providers, using NAT directly to the Microsoft data center, providing a very, very high speed connection.
And at this point, if you're using Express Route, the calculators become less relevant, because your connection is going to be quite fast, using Express Route.
This course details the process of moving your network to Office 365 by deploying a new Office 365 subscription. David Elfassy covers creating user accounts, adding domains, and configuring email, directories, conferencing, file sharing, and valuable business services such as PowerShell and SharePoint.
