<p>This article describes how to create a server resource pool for external or internal ELB instances.</p> <p>Both external and internal ELB support ECS and BMS hosts to build resource pools.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <p>&bull;&nbsp;You have created an external or internal ELB instance.</p> <p>&bull;&nbsp;For an external ELB instance, make sure you have created an ECS or other computing resources in any subnet under the DMZ network in the VPC where the ELB instance is located.</p> <p>&bull;&nbsp;For an internal ELB instance, make sure you have created an ECS or other computing resources in the subnet of VPC where the ELB instance is located.</p> <p><span style="font-size:18px"><strong>Procedures</strong></span></p> <p>1.&nbsp;Log in to the <a href="https://pinganyun.com/console/loadBalance/overview" target="_blank">ELB Console</a>.</p> <p>2.&nbsp;In the left navigation pane, click <strong>Instance Management</strong> and enter the<strong> Instance Management</strong> page.</p> <p>3.
