Step 2: Bind an EIP to an ECS In the EIP list, locate the target EIP, and click Bind in the Operation column. Select the ECS and bind the EIP to it. If the ECS has an EIP bound to it, unbind that EIP from the ECS first. Click OK. Parent Topic: EIP Configuration Examples
You can bind an EIP to the extended network interface of the ECS and configure policy-based routes to ensure that the ECS can access the Internet through the EIP. This section uses a Linux ECS as an example.
The memory usage of the ECS is higher than 80%. For details, see Why Is My Linux ECS Running Slowly? or Why Is My Windows ECS Running Slowly? Unstable carrier lines: The network between the local server and the cloud is unstable. Contact the carrier to check the network status.
Binding an EIP to an ECS Scenarios This section describes how to bind an EIP to an ECS by calling APIs. Prerequisites You have created an ECS. For details, see Purchasing an ECS.
Unbinding an EIP from an ECS Scenarios This section describes how to unbind an EIP from an ECS by calling APIs. Prerequisites You have created an ECS. For details, see Purchasing an ECS.
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.
If you want to change an EIP for your ECS, refer to Changing an EIP. Parent topic: EIP
Can Multiple EIPs Be Bound to an ECS? Scenarios Multiple EIPs can be bound to an ECS, but this operation is not recommended.
Interface of the ECS Step 5: Check Whether Required Security Group Rules Have Been Configured Step 6: Check Whether Traffic from the ECS Subnet Is Blocked Step 1: Check Whether the ECS Is Running Properly Check the ECS status.
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.
Why Is My Windows ECS Running Slowly? Why Is My Linux ECS Running Slowly?
On the Elastic Cloud Server page, click the name of the target ECS. The page providing details about the ECS is displayed. Click the Security Groups tab, expand the information of the security group, and view security group rules. Click the security group ID.
After a global EIP is bound to an ECS, the VPC of the ECS cannot be changed, and no more EIP can be bound to the ECS. A global EIP cannot be bound to a shared load balancer. Prerequisites The required instance (such as ECS or ELB) has been created.
For details, see Purchasing an ECS in Custom Config Mode. Click Submit. Return to the ECS list to view ECS-A01 you have bought. Log in to ECS-A01 and check whether the ECS has obtained an IPv6 address.
Global Internet Gateway After a global EIP is bound to an ECS, a global internet gateway is required to connect the VPC of the ECS to the global EIP so that the ECS can access the Internet through the global EIP.
Step 3: Buy an EIP and Bind It to the ECS Buy an EIP and bind it to the ECS so that the ECS can access the Internet. Step 4: Test Network Connectivity To test ECS connectivity, you can: Log in to the ECS from the local PC. Access the Internet from the ECS using an EIP.
Enabling or Disabling IPv6 EIP Scenarios If your applications deployed on an ECS need to provide services through IPv6 addresses but the ECS does not support IPv6 networks and you do not want to build an IPv6 network either, you can use the IPv6 EIP function to quickly meet your requirements
Global Internet Gateway Overview After a global EIP is bound to an ECS, a global internet gateway is required to connect the VPC of the ECS to the global EIP so that the ECS can access the Internet through the global EIP.
If you do not select this option, you need to manually add a route to the route table (default or custom) associated with the VPC subnet of your ECS to direct traffic to the global internet gateway. - Click OK.
Binding an EIP to an ECS Scenario You can bind an EIP to an ECS to enable the ECS to access the Internet.
