What is the difference between normal MVC and Azure MVC forms authentication systems?

Question

I see in Visual Studio 2013 when creating a default MVC application and creating a Windows Azure cloud service MVC application that the Forms authentication tables differ:

Normal MVC:

• UserProfile
• webpages_Membership
• webpages_OAuthMembership
• webpages_Roles
• webpages_UsersInRoles

Azure MVC:

• AspNetRoles
• AspNetUserClaims
• AspNetUserLogins
• AspNetUserRoles
• AspNetUsers

Questions:

• What is the name for each system (for Googling)?
• Why are they different?
• Which is the more recent\better system that I should use?

Even the code for AccountController.Register() differs:

Normal MVC:

WebSecurity.CreateUserAndAccount(model.UserName, model.Password);
WebSecurity.Login(model.UserName, model.Password);

Azure MVC:

var user = new ApplicationUser() { UserName = model.UserName };
var result = await UserManager.CreateAsync(user, model.Password);

Answer 1

The Azure way is called ASP.NET Identity and is MVC 5. The old way is called ASP.NET membership.

The new way is more powerful.
