Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Overrides Object.Equals(Object).)
	Equals(RoleEnvironmentTopologyChange)	Determines whether the specified RoleEnvironmentTopologyChange object is equal to the current object.
	Finalize()	(Inherited from Object.)
	GetHashCode()	Retrieves the hash code that corresponds to the current object.(Overrides Object.GetHashCode().)
	GetType()	(Inherited from Object.)
	MemberwiseClone()	(Inherited from Object.)
	ToString()	(Inherited from Object.)

Remarks

The topology refers to the number of instances and the number of endpoints that are defined for a role. For more information about service definitions, see Windows Azure Service Definition Schema.

Note

At least one internal endpoint must be defined for a role in order to raise a RoleEnvironmentTopologyChange. For more information about defining endpoints, see Enable Communication for Role Instances in Windows Azure.

Important

It is highly recommended that you configure the cloud service to run at least two instances of the role. When you deploy two or more role instances in different fault and upgrade domains, your Internet facing roles have external connectivity at least 99.95% of the time. For more information, see Service Level Agreements.
