Shared Bandwidth Overview

+

Shared bandwidth allows multiple EIPs to share the same bandwidth. All ECSs, BMSs, and load balancers that have EIPs bound in the same region can share a bandwidth.

+

When you host a large number of applications on the cloud, if each EIP uses an independent bandwidth, a lot of bandwidths are required, increasing O&M workload. If all EIPs share the same bandwidth, VPCs and the region-level bandwidth can be managed in a unified manner, simplifying O&M statistics and network operations cost settlement.

An IPv6 client on the Internet can access the ECS that has an EIP bound in a VPC. For details about the implementation and constraints, see How Does an IPv6 Client on the Internet Access the ECS That Has an EIP Bound in a VPC?

+
+

Follow-Up Procedure

After an ECS with an EIP bound is created, the system generates a domain name in the format of ecs-xx-xx-xx-xx.compute.xxx.com for the EIP by default. xx-xx-xx-xx indicates the EIP, and xxx indicates the domain name of the cloud service provider. You can use the domain name to access the ECS.

+
You can use any of the following commands to obtain the domain name of an EIP:
  • ping -a EIP
  • nslookup [-qt=ptr] EIP
  • dig -x EIP

What Are the Differences Between a Dedicated Bandwidth and a Shared Bandwidth? Can a Dedicated Bandwidth Be Changed to a Shared Bandwidth or the Other Way Around?

+

Dedicated bandwidth: The bandwidth can only be used by one EIP and the EIP can only be used by one cloud resource, such as an ECS, a NAT gateway, or a load balancer.

+

Shared bandwidth: The bandwidth can be shared by multiple EIPs. Adding an EIP to or removing an EIP from a shared bandwidth does not affect your workloads.

+

A dedicated bandwidth cannot be changed to a shared bandwidth or the other way around. You can purchase a shared bandwidth for your EIPs.

What Is a Quota?

+

What Is a Quota?

A quota limits the quantity of a resource available to users, thereby preventing spikes in the usage of the resource. For example, a VPC quota limits the number of VPCs that can be created.

+

You can also request for an increased quota if your existing quota cannot meet your service requirements.

+
+

How Do I View My Quotas?

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. In the upper right corner of the page, click .

    The Service Quota page is displayed.

    +
  4. View the used and total quota of each type of resources on the displayed page.

    If a quota cannot meet service requirements, apply for a higher quota.

    +
+
+

How Do I Apply for a Higher Quota?

The system does not support online quota adjustment. If you need to adjust a quota, call the hotline or send an email to the customer service mailbox. Customer service personnel will timely process your request for quota adjustment and inform you of the real-time progress by making a call or sending an email.

+

Before dialing the hotline number or sending an email, make sure that the following information has been obtained:

+ +

Learn how to obtain the service hotline and email address.

What Are the Priorities of the Custom Route and EIP If Both Are Configured for an ECS to Enable the ECS to Access the Internet?

+

The priority of an EIP is higher than that of a custom route in a VPC route table. For example:

+

The VPC route table of an ECS has a custom route with 0.0.0.0/0 as the destination and NAT gateway as the next hop.

+

If an ECS in the VPC has an EIP bound, the VPC route table will have a policy-based route with 0.0.0.0/0 as the destination, which has a higher priority than its custom route. In this case, traffic is forwarded to the EIP and cannot reach the NAT gateway.

How Does an IPv6 Client on the Internet Access the ECS That Has an EIP Bound in a VPC?

+

Users with IPv6 clients can call APIs to assign IPv6 EIPs and bind the EIPs to ECSs. Then, the users can use the EIP to access the ECSs in the VPC over the Internet.

+

For details, see Floating IP Address (IPv6) > Creating a Floating IP Address in the Virtual Private Cloud API Reference. The NAT64 gateway in the data center will convert the IPv6 EIP to the IPv4 address. (The last 32 bits of the obtained IPv6 EIP is the IPv4 EIP.)

+

After users who use IPv6 clients bind an IPv6 EIP to an ECS, the data flow is shown in Figure 1.

How Do I Access an ECS with an EIP Bound from the Internet?

Each ECS is automatically added to a security group after being created to ensure its security. The security group denies access traffic from the Internet by default. To allow external access to ECSs in the security group, add an inbound rule to the security group.

You can set Protocol to TCP, UDP, ICMP, or All as required on the page for creating a security group rule.

Can I Bind Multiple EIPs to an ECS?

+

Scenarios

You can bind multiple EIPs to an ECS. However, this configuration is not recommended.

+

To bind multiple EIPs to an ECS, you must manually configure routes.

+
+

Configuration Example

Table 1 lists ECS configurations.

+ +
+ + + + + + + + + + + + + + + + + + + +
Table 1 ECS configurations

Parameter

+

Configuration

+

Name

+

ecs_test

+

Image

+

CentOS 6.5 64bit

+

EIP

+

2

+

Primary NIC

+

eth0

+

Secondary NIC

+

eth1

+
+
+

Example 1:

+
If you are required to access public network 11.11.11.0/24 through standby NIC eth1, perform the following operations to configure a route:
  1. Log in to the ECS.
  2. Run the following command to configure a route:

    ip route add 11.11.11.0/24 dev eth1 via 192.168.2.1

    +

    In the preceding command, 192.168.2.1 is the gateway IP address of standby NIC eth1.

    +
+
+

Example 2:

+

Based on example 1, if you are required to enable routing for default public network traffic through standby NIC eth1, perform the following operations to configure a route:

+
  1. Log in to the ECS.
  2. Run the following command to delete the default route:

    ip route delete default

    +

    Exercise caution when deleting the default route because this operation will interrupt the network and result in SSH login failures.

    +
    +
  3. Run the following command to configure a new default route:

    ip route add 0.0.0.0/0 dev eth1 via 192.168.2.1

    +

    In the preceding command, 192.168.2.1 is the gateway IP address of standby NIC eth1.

What Is Elastic IP?

+

The Elastic IP (EIP) service enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidths. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, or load balancers.

+

Each EIP can be used by only one cloud resource at a time.

The cloud system provides two types of user permissions by default: user management and resource management. User management refers to the management of users, user groups, and user group rights. Resource management refers to the control operations that can be performed by users on cloud service resources.

Region and AZ

+

Concept

A region and availability zone (AZ) identify the location of a data center. You can create resources in a specific region and AZ.

+ +

Figure 1 shows the relationship between regions and AZs.

+
Figure 1 Regions and AZs
+
+

Selecting a Region

Select a region closest to your target users for lower network latency and quick access.

+
+

Selecting an AZ

When deploying resources, consider your applications' requirements on disaster recovery (DR) and network latency.

+ +
+

Regions and Endpoints

Before you use an API to call resources, specify its region and endpoint. For more details, see Regions and Endpoints.

Overview

+

If your ECSs need to access the Internet (for example, the ECSs functioning as the service nodes for deploying a website), you can follow the procedure shown in Figure 1 to bind EIPs to the ECSs.

+
Figure 1 Configuring the network
+

Table 1 describes the different tasks in the procedure for configuring the network.

+ +
+ + + + + + + + + + + + + + + + + + + +
Table 1 Configuration process description

Task

+

Description

+

Create a VPC.

+

This task is mandatory.

+

A created VPC comes with a default subnet you specified.

+

After the VPC is created, you can create other required network resources in the VPC based on your service requirements.

+

Create another subnet for the VPC.

+

This task is optional.

+

If the default subnet cannot meet your requirements, you can create one.

+

The new subnet is used to assign IP addresses to NICs added to the ECS.

+

Assign an EIP and bind it to an ECS.

+

This task is mandatory.

+

You can assign an EIP and bind it to an ECS so that the ECS can access the Internet.

+

Create a security group.

+

This task is mandatory.

+

You can create a security group and add ECSs in the VPC to the security group to improve ECS access security. After a security group is created, it has a default rule, which allows all outgoing data packets. ECSs in a security group can access each other without the need to add rules.

+

Add a security group rule.

+

This task is optional.

+

If the default rule does not meet your service requirements, you can add security group rules.

Step 1: Create a VPC

+

Scenarios

A VPC provides an isolated virtual network for ECSs. You can configure and manage the network as required.

+

You can create a VPC by following the procedure provided in this section. Then, create subnets, security groups, and assign EIPs by following the procedure provided in subsequent sections based on your actual network requirements.

+
+

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. On the console homepage, under Network, click Virtual Private Cloud.
  4. Click Create VPC.
  5. On the Create VPC page, set parameters as prompted.

    A default subnet will be created together with a VPC and you can also click Add Subnet to create more subnets for the VPC.

    +

    Description

    +

    Example Value

    +

    Basic Information

    +

    Region

    +

    Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest you.

    +

    eu-de

    +

    Basic Information

    +

    Name

    +

    The VPC name.

    +

    +

    The following CIDR blocks are supported:

    +

    10.0.0.0/8-24

    +

    172.16.0.0/12-24

Step 2: Create a Subnet for the VPC

+

Scenarios

A VPC comes with a default subnet. If the default subnet cannot meet your requirements, you can create one.

+

The subnet is configured with DHCP by default. When an ECS in this subnet starts, the ECS automatically obtains an IP address using DHCP.

+
+

Procedure

  1. Log in to the management console.
  1. Click in the upper left corner and select the desired region and project.
  2. On the console homepage, under Network, click Virtual Private Cloud.
  3. In the navigation pane on the left, click Subnets.
  4. Click Create Subnet.

    The Create Subnet page is displayed.

    +
  5. Set the parameters as prompted.

    +

    +

    The gateway address of the subnet.

    +

    192.168.0.1

    +

    DNS Server Address

    +

    By default, two DNS server addresses are configured. You can change them if necessary. A maximum of five DNS server addresses can be configured. Multiple IP addresses must be separated using commas (,).

    +

    100.125.x.x

    +

    NTP Server Address

    +

    The IP address of the NTP server. This parameter is optional.

    +

    You can configure the NTP server IP addresses to be added to the subnet as required. The IP addresses are added in addition to the default NTP server addresses. If this parameter is left empty, no IP address of the NTP server is added.

    +

    A maximum of four IP addresses can be configured. Multiple IP addresses must be separated using commas (,).

    +

    192.168.2.1

    +

    Tag

    +

    The subnet tag, which consists of a key and value pair. You can add a maximum of 20 tags to each subnet.

    +

    The tag key and value must meet the requirements listed in Table 2.

    +
    • Key: subnet_key1
    • Value: subnet-01

    +

    subnet-01

    +
    +
    +
  6. Click OK.
+
+

Precautions

When a subnet is created, there are five reserved IP addresses, which cannot be used. For example, in a subnet with CIDR block 192.168.0.0/24, the following IP addresses are reserved:

+
  • 192.168.0.0: Network ID. This address is the beginning of the private IP address range and will not be assigned to any instance.
  • 192.168.0.1: Gateway address.
  • 192.168.0.253: Reserved for the system interface. This IP address is used by the VPC for external communication.
  • 192.168.0.254: DHCP service address.
  • 192.168.0.255: Network broadcast address.
+

If you configured the default settings under Advanced Settings during subnet creation, the reserved IP addresses may be different from the default ones, but there will still be five of them. The specific addresses depend on your subnet settings.

Step 3: Assign an EIP and Bind It to an ECS

+

Scenarios

You can assign an EIP and bind it to an ECS so that the ECS can access the Internet.

+
EIPs for dedicated load balancers:
  • In the eu-de region, if you choose to assign an EIP when you create a dedicated load balancer on the management console or using APIs, EIPs for dedicated load balancers (5_gray) will be assigned.
  • Do not bind EIPs of this type to non-dedicated load balancers.
  • Do not add EIPs of the dedicated load balancer type and other types to the same shared bandwidth. Otherwise, the bandwidth limit policy will not take effect.
+
+
+
+

Assigning an EIP

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. On the console homepage, under Network, click Elastic IP.

An IPv6 client on the Internet can access the ECS that has an EIP bound in a VPC. For details about the implementation and constraints, see How Does an IPv6 Client on the Internet Access the ECS That Has an EIP Bound in a VPC?

+
+

Follow-Up Procedure

After an ECS with an EIP bound is created, the system generates a domain name in the format of ecs-xx-xx-xx-xx.compute.xxx.com for the EIP by default. xx-xx-xx-xx indicates the EIP, and xxx indicates the domain name of the cloud service provider. You can use the domain name to access the ECS.

+
You can use any of the following commands to obtain the domain name of an EIP:
  • ping -a EIP
  • nslookup [-qt=ptr] EIP
  • dig -x EIP
