In this post, I will try to clarify the doubts around Azure AD.
What is Azure AD and what its not?
Azure AD is the Active Directory services hosted at Microsoft datacentres and provided as a service (SaaS) to its customer. Its extremely reliable and secure.
Like On premise AD it provides Authentication (User ID & Password) and authorization (access to services).
It doesn’t provide domain controllers in Azure and group policies. You cannot create trusts between different AD forests\domains.
Its not a replacement of On premise AD (for medium to large organization). In fact it complements the On premise AD in today’s cloud world.
You can connect your On Premise AD with Azure AD and keep them synchronized.
It doesn’t have all the flexibility and control you have with On Premise AD, you will have to use the features that Microsoft offers.
What is the purpose of Azure AD?
It helps organization Increase productivity by allowing users to access business applications from anywhere using single identity with required controls and security. Also, get self service for passwords, account unlocks and groups management.
It allows organization to easily achieve Single Sign-on (SSO) with cloud applications such as SAPBYD, JIRA, O365, G-Suite, Salesforce etc. and on premise applications. So, they will have a single identity for all the business application resulting in ease of management with increased security.
Automate user provisioning and de-provisioning in multiple systems (a very costly, error prone and inefficient process otherwise)
Increase security by using features like multi-factor authentication, Conditional Access, Identity Protection and Privilege Identity management.
Helps to achieve digital transformation.
