Windows Azure Diagnostics empowers you to gather diagnostic data from an application running in Windows Azure. Diagnostic data is used for capacity planning and evaluation.

Azure Queues give a solid, diligent messaging between and within the services. They also highlight a very straightforward rest-based get/put/peek interface.

Scaling by including extra instances is frequently referred to as scaling out. Windows Azure likewise supports scaling up by utilizing bigger roles rather than more role instances.

By adding and expelling role instances to our Windows Azure application while it is running, we can adjust the execution of the application against its running costs.

An autoscaling solution reduces the amount of manual work engaged in dynamically scaling an application.

Windows Azure runs and stores the information on Microsoft data centers.

The main features are as follows:

Private clouds are those that are constructed solely for an individual enterprise. They enable a firm to have applications in the cloud while tending to concerns with respect to data security and control that is frequently ailing in a public cloud environment.

Private cloud is otherwise called an internal cloud or enterprise cloud and dwells on the organization’s Intranet or hosted data center where the data is protected.

IaaS: IaaS is short for Infrastructure as a Service. It offers a range of capabilities, such as OS and network connectivity, that are at the infrastructural level. It follows a pay-per-use policy. It is used to host applications. Azure VM and VNET are examples of this kind of infrastructure.

PaaS: PaaS is an acronym for Platform as a Service. It primarily includes underlying infrastructure abstraction that allows quicker development of applications without the hassle of hosting management. Azure web apps, cloud services, storage services, etc., are all examples of PaaS. 

SaaS: SaaS stands for Software as a Service.  These applications are delivered with the help of a service delivery model where applications are simply used by an organization. SaaS follows subscription-based payments or ads. Examples of SaaS are Gmail, Office 365, SharePoint Online, etc.

No. Azure Internal Load Balancer supports only private IP addresses.

Azure Resource Manager, offered by Azure, provides management and application deployment in Azure. The management layer helps to build, modify, or delete resources in the Azure subscription account. It is useful while managing access controls, locks, and security of resources.

NSG or Network Security Group contains a list of ACL rules that allow or deny network traffic to subnets, network interface cards (NICs) linked to a subnet, or both. When an NSG is connected to a subnet, the ACL rules are for all virtual machines that are located in that subnet. The traffic restrictions to an individual NIC are achieved by linking the NSG directly to that NIC.

Azure Redis Cache is an in-memory Redis cache system by Azure that helps web applications to optimize performance. Data is fetched from the backend database and stored in the Redis cache for the first request. On subsequent requests, data is fetched from the Redis cache. Azure Redis cache provides powerful and secure caching mechanisms by using Azure Cloud.
