Office 365 and Azure

We are currently utilizing Office 365 for SharePoint, OneDrive and Exchange.   However I notice that Azure is part of our E1 plan.  What exactly is Azure and what can it do for me in practical terms?  All the help I can get is appreciated.

We currently have a domain on our network with an AD controller.  How does Azure help us there also?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There's a bit of a marketing mess created by Microsoft here. What's included in O365 is Azure AD, this is the identity bit of the whole solution. In other words, its sort of the backend of the O365 services. Some of the more advanced security/auditing features for O365 do require the Azure AD Premium plan, which is yet another SKU you can purchase, but that's optional.

"Only" Azure on the other hand is the IaaS/PaaS offering of Microsoft, aka the Public cloud. It allows you to run virtual machines which you can use to setup a DC for example, but this is NOT included in the O365 subscription. It requires a different subscription. It also offers a lot more than just running VMs...

As per my knowledge Cloud provides three types of services-
SAAS – Software as a Service
IAAS – Infrastructure as a Service
PAAS  - Platform as a Service
O365 is work on the basis of SAAS that serves version of Ms Office suite (Outlook, PowerPoint, Word, Excel, Lync, One Note and Access) online no matter about the size and needs
Azure is consists of Windows Azure, SQL Azure, AppFabric, and Azure Marketplace. Windows azure is working on the platform of IAAS & PAAS. With IAAS Model windows azure consist three main components Compute, Storage and Virtual Network
With PAAS It can be used for Development, Service Hosting and Service management Environment.

Can I use axure ad to replace my network AD?

No. It's not an AD in the 'traditional' meaning of the word, for example there are no OUs, no GPOs, etc.
