Measures reported by AlibabaVPCTest

A virtual private cloud (VPC) is a private network dedicated for your use. You have full control over your VPC. For example, you can specify the CIDR block and configure route tables and gateways. In a VPC, you can deploy Apsara Stack resources, such as Elastic Compute Service (ECS) instances, ApsaraDB RDS instances, and Server Load Balancer (SLB) instances.

Furthermore, you can connect your VPC to other VPCs or on-premises networks to create a custom network environment. This way, you can migrate applications to the cloud and extend data centers.

Using the AlibabaVPCTest test, administrators can quickly identify the VPCs that have been created, and can understand the status and configuration of each VPC-eg., how many route tables, gateways, vRouters, vSwitches etc., have been configured per VPC.

Outputs of the test : One set of results for VPC that is configured on the Alibaba cloud.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_vpc Indicates the status of this VPC.   The values that this measure reports and their corresponding numeric values are listed below:

Measure Value Numeric Value
Available 1
Not Bound 2

Note:

This measure reports the Measure Values listed in the table above to indicate the current status of a VPC. In the graph of this measure however, the same is indicated using the numeric equivalents only.

Use the detailed diagnosis of this measure to know more about this VPC.
Route_table Indicates the number of route tables configured in this VPC. Number By default, a maximum of 9 custom route tables can alone be created per VPC. You can override this default limit by requesting a quota increase using the Quota Management Page in Alibaba cloud console.

To know which route tables are created for this VPC, use the detailed diagnosis of this measure.
VSwitch_count Indicates the number of vSwitches configured for this VPC. Number A vSwitch is a basic network component that connects different cloud resources in a VPC. After you create a VPC, you can create a vSwitch to divide your VPC into multiple subnets. vSwitches deployed in a VPC can communicate with each other over the private network. You can deploy your applications in vSwitches that belong to different zones to improve service availability.

By default, a maximum of 24 vSwitches can be configured per VPC. You can override this default limit by requesting a quota increase using the Quota Management Page in Alibaba cloud console.

To know which vSwitches are created in this VPC, use the detailed diagnosis of this measure.
Ecs_instance Indicates the number of ECS instances deployed in this VPC. Number Elastic Compute Service (ECS) is a high-performance, stable, reliable, and scalable IaaS-level service provided by Alibaba Cloud. ECS eliminates the need to invest in IT hardware up front and allows you to quickly scale computing resources on demand. This makes ECS more convenient and efficient than physical servers. ECS provides a variety of instance types that suit different business needs and help boost business growth.

To know which ECS instances are deployed in this VPC, use the detailed diagnosis of this measure.
Slb_instance Indicates the number of SLB instances deployed in this VPC. Number Alibaba Cloud Server Load Balancer (SLB) distributes traffic among multiple instances to improve the service capabilities of your applications. You can use SLB to prevent single point of failures (SPOFs) and improve the availability and the fault tolerance capability of your applications.

To know which SLB instances are deployed in this VPC, use the detailed diagnosis of this measure.
Nat_gateway Indicates the number of NAT gateways configured in this VPC. Number NAT gateways are enterprise-class gateways that provide the Source Network Address Translation (SNAT) and Destination Network Address Translation (DNAT) features. Each NAT gateway provides a throughput capacity of up to 10 Gbit/s. NAT gateways also support cross-zone disaster recovery.

Using the detailed diagnosis of this measure, you can quickly identify the NAT gateways configured in this VPC.
Security_group Indicates the number of security groups configured in this VPC. Number Security groups function as virtual firewalls that provide Stateful Packet Inspection (SPI) and packet filtering capabilities to isolate security domains on the cloud. You can configure security group rules to control the inbound and outbound traffic of ECS instances in security groups.

Using the detailed diagnosis of this measure, you can quickly identify the security groups configured in this VPC.
