Six scenarios for private network (VPC) applications

Six scenarios for private network (VPC) applications

A private network (VPC) is an isolated network environment with ARM hostingflexible configuration to meet different application scenarios.

Managed application

You can host the application programs that provide information services Cloud platfrom providerfor external development in a VPC. In addition, you can create security group rules and access the internal control whitelist to manage and control Internet access. You can also isolate data access control between the application research server and the database, deploy the Web server in a subnet that can effectively access the public network, and deploy the application analysis database in a subnet that is not properly configured with public network access.

An application that hosts active access to a public network

You can host applications that need active access virtual private cloudto public networks in a VPC's subnet and route their traffic through network address translation (NAT) gateways. By configuring SNAT rules, an instance in a subnet can access the Internet without exposing its private IP address, and the public IP can be replaced at any time to avoid outside attacks.

Cross-availability zone Dr

By creating a switch, you can divide a private network into one or more subnets. Internetwork communication between different switches in the same private network. By deploying resources in switches in different availability zones, disaster tolerance across availability zones can be achieved.

Service system isolation

Logical isolation between VPCS. If you have multiple service systems, such as a production environment and a test environment, you can use multiple VPCS to isolate services. To communicate with each other, you can set up a peer connection between two VPCS.

Building a hybrid cloud

A VPC provides a dedicated network connection that connects local data centers to a VPC and extends the local network architecture. In this way, you can seamlessly migrate your on-premises applications to the cloud without having to change how your applications are accessed.

The traffic of multiple applications fluctuates greatly

If the bandwidth fluctuation of your application system is greatly affected, you can configure DNAT forwarding rules through the NAT gateway at the same time, and then add the EIP to the data sharing network bandwidth to achieve multi-IP bandwidth sharing and reduce the peak and trough effect, thereby reducing your cost.
