Windows Azure First Experience-Features introduction

Introduction to Windows Azure features

With the advent of the cloud computing era, many people feel at foggy. What is the concept of cloud? I believe no one can give a reasonable explanation, anyway I understand now is that the public cloud is a server hosted in the data center, provided that the data center provides all the hardware and software services, but this interpretation is not entirely correct, is not completely wrong.

Windows Azure is divided into Chinese and international versions, and the two are functionally different. The international version of Azure features is relatively rich. The Windows Azure Service room deployed in China is mainly located in Beijing and Shanghai. Differentiate by affinity groups on Windows Azure. So what is an affinity group? An affinity group is a way to group services that need to work together to achieve the best performance in your Windows Azure subscription. After you create an affinity group, the affinity group lets Windows Azure know that all services that belong to your affinity group are running in the same datacenter cluster. For example, if you want to have your data and code run with the service, specify the same affinity group for those services. This way, when you deploy these services, Windows Azure places these services in the datacenter as closely as possible to each other. This reduces latency and improves performance while potentially reducing costs.

An affinity group is defined at the subscription level, and the name of each affinity group must be unique within the subscription. When you create a virtual network, you can either use an affinity group that you created previously or create a new affinity group. If you have a previously created affinity group that you want to use, you only need to specify that affinity group when you create a new virtual network. Any previously deployed cloud services within the affinity group will be automatically assigned to run as close as possible to other cloud services deployed to your new virtual network.

Windows Azrue offers a number of features that allow you to migrate your on-premises services to Azure to ensure service stability, guaranteed service stability, but high charges and charges for all services running on Azure, but one benefit is that Windows Services on azure are calculated on a per-day, space-use basis. For example, the traffic is calculated according to MB, the disk space utilization is based on GB, service is based on the number, version calculation, etc., can refer to the world's Internet Information: https://windowsazure.cn

3. Cloud service Features: The cloud service feature that is understood on Windows Azure is the extranet IP Association for the new virtual machine, because the newly created virtual machines on Windows Azure Publish the service (create a cloud service for the first time with the virtual opportunity prompt); Cloud services on Azure I value, because this feature for real physical environment has a great improvement, so to speak; if the real physical environment of the server to do internal IP to the external IP of the release is generally one-to-do, this is a waste of the corresponding network IP. At the same time, the most important thing for individuals is that this function is very convenient for doing load balancing.
