Azure terminologies

The following is the list of Azure terminologies that are required in NetScaler ADM:

Term Definition
Azure Load Balancer The Azure load balancer is a resource that distributes incoming traffic among NetScaler VPX instances in a network. Traffic is distributed among virtual machines defined in a load-balancer set. A load balancer can be external or internet-facing, or it can be internal.
Traffic Manager The Azure traffic manager is the DNS based load balancer in Microsoft Azure. It sends the incoming traffic to desired NetScaler VPX instance in a network.
Azure Resource Manager (ARM) ARM is the new management framework for services in Azure. Azure Load Balancer is managed using ARM-based APIs and tools.
Back-End Address Pool These IP addresses are associated with the virtual machine NIC to which load is distributed.
BLOB Binary Large Object – Any binary object like a file or an image that can be stored in Azure storage.
Front-End IP Configuration An Azure Load balancer can include one or more front-end IP addresses, also known as a virtual IPs (VIPs). These IP addresses serve as ingress for the traffic.
Instance-Level Public IP (ILPIP) An ILPIP is a public IP address that you can assign directly to your virtual machine or role instance instead of cloud service. This IP does not take the place of the VIP (virtual IP) that is assigned to your cloud service. Rather, it’s an extra IP address that you can use to connect directly to your virtual machine or role instance.
Inbound NAT Rules These rules map a public port on the load balancer to a port for the specific virtual machine in the back end address pool.
IP-Config It is an IP address pair (public IP and private IP) associated with an individual NIC. In an IP-Config, the public IP address can be NULL. Each NIC can have multiple IP-Config associated with it up to 255.
Load Balancing Rules A rule property that maps a given front-end IP and port combination to a set of back-end IP addresses and port combination. With a single definition of a load balancer resource, you can define multiple load balancing rules. Each rule reflects a combination of a front end IP and port and back end IP and port associated with virtual machines.
Network Security Group (NSG) NSG contains a list of Access Control List (ACL) rules that allow or deny network traffic to your virtual machine instances in a virtual network. NSGs can be associated with either subnets or individual virtual machine instances within that subnet.
Private IP address This address is an IP address used for communication within an Azure virtual network, and your on-premises network when a VPN gateway is used to extend your network to Azure. Private IP addresses allow Azure resources to communicate with other resources. The communication in a virtual network or an on-premises network is through a VPN gateway or ExpressRoute circuit. This communication does not require an internet-reachable IP address. In the Azure Resource Manager deployment model, a private IP address is associated with the virtual machines, Internal Load Balancer (ILB), and Application Gateways of Azure.
Probes Health probes used to check the availability of virtual machines instances in the back end address pool.
Public IP Addresses (PIP) PIP is used for communication with the Internet. It includes Azure public-facing services associated with virtual machines, Internal Load Balancer (ILB), VPN gateways, and Application Gateways of Azure
Region An area within geography that does not cross national borders, it contains one or more data centers. Pricing, regional services, and offer types are exposed at the region level. A region is typically paired with another region, which spans a large distance from a regional pair. Regional pairs are also used as a mechanism for disaster recovery and high availability scenarios. Also known as location.
Resource Group A container in Resource Manager holds related resources for an application. The resource group can include all the resources for an application, or only those resources that are logically grouped.
Storage Account An Azure storage account gives you access to the Azure blob, queue, table, and file services in Azure Storage. Your storage account provides the unique namespace for your Azure storage data objects.
Virtual Machine The software implementation of a physical computer that runs an operating system. Multiple virtual machines can run simultaneously on the same hardware. In Azure, virtual machines are available in various sizes.
Virtual Network An Azure virtual network is a representation of your own network in the cloud. It is logically isolated and dedicated to your subscription in Azure cloud. You can control the IP address blocks, DNS settings, security policies, and route tables within this network.
