In this guide, Azure Front Door pools two instances of a web application that run in different Azure regions. You create a Front Door configuration based on equal-weighted and same priority backends. This configuration directs traffic to the nearest site that runs the application.
Azure Front Door continuously monitors the web application. The service provides automatic failover to the next available site when the nearest site is unavailable.
In this guide, you will use the Azure portal to create an application gateway. Then you test it to make sure it works correctly. The application gateway directs application web traffic to specific resources in a backend pool. You assign listeners to ports, create rules, and add resources to a backend pool.
In this guide, you will learn how to set up disaster recovery of on-premises Hyper-V VMs to Azure, Select your replication source and target, Enable replication for a VM. The Azure Site Recovery service contributes to your disaster-recovery strategy by managing and orchestrating replication, failover, and failback of on-premises machines and Azure virtual machines (VMs).
In this guide, you will see how to implement and configure Azure storage services Blob and File share. The Azure Storage platform is Microsoft’s cloud storage solution for modern data storage scenarios. Core storage services offer a massively scalable object store for data objects, disk storage for Azure virtual machines (VMs), a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store.
In this guide, you will see building solutions for high availability using Availability Zones. High availability refers to a set of technologies that minimize IT disruptions by providing business continuity of IT services through redundant, fault-tolerant, or failover-protected components inside the same data centre. In our case, the data center resides within one Azure region.
In this guide, you will learn how to create a deployment slot as a staging environment in App Service.
Azure Traffic Manager allows you to regulate the distribution of user traffic by using DNS to direct requests to the most appropriate service endpoint supported on a traffic-routing method and therefore the health of the endpoints.
Azure traffic manager selects an endpoint based on the configured routing method. It supports a variety of traffic-routing methods to suit different application needs. After the selection of endpoints, the client is connected directly to the appropriate service point. It also provides endpoint health checks and automatic failover. It also enables you to build a highly available application that is resilient to failure, including the failure of an entire Azure region.
Traffic Manager uses DNS to direct client requests to the most appropriate service endpoint based on a traffic-routing method and the health of the endpoints. An endpoint is any Internet-facing service hosted inside or outside of Azure. It provides a range of traffic-routing methods and endpoint monitoring options to suit different application needs and automatic failover models. It is resilient to failure, including the failure of an entire Azure region.
Azure Traffic Manager distributes the traffic based on one of the six traffic-routing methods that determine which endpoint is returned within the DNS response.
These following traffic routing methods which are available:
When you select the priority routing method, it contains a prioritized list of service endpoints where the primary service endpoint has the highest priority for all traffic. If the primary service endpoint is unavailable, it redirects the traffic to the second priority endpoint and so on.
The weighted routing method is used when you want to distribute traffic evenly or to use pre-defined weights across a set of endpoints. In this traffic-routing method, you allocate a weight which is an integer from 1 to 1000, to each endpoint in the Microsoft Azure Traffic Manager profile configuration.
This traffic routing method is used when you want to improve the responsiveness of many applications by routing traffic to the location that is closest to the user. The ‘closest’ endpoint isn’t necessarily closest as measured by geographic distance. Instead, the ‘Performance’ traffic-routing method determines the closest endpoint by measuring network latency.
In Geographic routing, each endpoint associated with that profile must have a set of geographic regions assigned thereto. When a region or a set of regions is assigned to an endpoint, any requests from those regions get routed only thereto endpoint.
You can select MultiValue for Azure Traffic Manager profiles which may only have IPv4/IPv6 addresses as endpoints. When a question is received for this profile, all healthy endpoints are returned.
Select the Subnet traffic-routing method to map sets of end-user IP address ranges to a specific endpoint within an Azure Traffic Manager profile. When a request is received, the endpoint returned are getting to be the one mapped for that request’s source IP address.
Some of the features are discussed below:
It provides high availability for your critical applications by monitoring your endpoints and delivering automatic failover when an endpoint goes down.
Azure allows you to run cloud services or websites in data centres located all over the world. It enhances application responsiveness by directing traffic to the endpoint with the lowest network latency for the client.
You can perform planned maintenance operations on your applications without downtime. It can direct traffic to alternative endpoints while the unkeep is ongoing.
Microsoft Azure Traffic Manager supports external, non-Azure endpoints enabling it to be used with hybrid cloud and on-premises deployments, including the “burst-to-cloud”, “migrate-to-cloud,” and “failover-to-cloud” scenarios.
Using nested Azure Traffic Manager profiles, multiple traffic-routing methods are often combined to make sophisticated and versatile rules to scale to the requirements of larger, more complex deployments.
Step 1) Log in to Azure Portal (Please make sure you have a subscription before doing all this. If you created a free account for the first time, you’ll already have a FREE TRIAL subscription for 1 month).
If you don’t know how to create an instance or virtual machine then click on Create a Virtual Machine to know more
Create a Traffic Manager profile that directs user traffic based on endpoint priority
Step 2) On the upper-left side of the screen, select Create a resource > Networking > Traffic Manager profile.
Step 3) In the Create Traffic Manager profile, enter, or select these settings
Name: Enter a unique name for your Traffic Manager profile.
Step 4) Select Create and its done now you have created successfully traffic manager profile on Azure
