Overview
Before creating an eSurfing Cloud DCS Redis instance, you need to make some preparations. First, you need to set up a virtual private cloud (VPC), which is an isolated network environment to host the Redis instance. Next, you need to create a subnet, which is a subnet inside the VPC to separate different parts and regions. Finally, you need to configure a security group to control inbound and outbound traffic rules to ensure the security of the Redis instance.
Each DCS Redis instance is deployed in a specific VPC and associated with a specific subnet and security group. This allows you to configure and manage the network environment of your Redis instance on your own, and provides security protection policies. If you already have existing VPCs, subnets, and security groups, you can reuse them without having to additional creation. This saves time and resources, and also ensures consistency and reliability.
Preparing Instance Dependencies
Before purchasing a DCS Redis instance, you need to prepare the following dependency resources
VPCs and Subnets
VPCs and subnets can be reused, or you can use different VPCs and subnets to configure your Redis instance based on your actual needs. When creating a VPC and a subnet, keep in mind the following requirements:
l The VPC and the eSurfing Cloud DCS Redis should be in the same region.
l If you have no special requirements, you can use the default configuration to create VPCs and subnets.
For operations about how to create a VPC and a subnet, refer to Virtual Private Cloud (VPC) - Creating a VPC and a Subnet, and Building a Private Network.
If you want to create and use a new subnet in an existing VPC, refer to Virtual Private Cloud (VPC) - Subnet Management - Creating a Subnet.
Security Group
Security groups can be reused, or you can use different security groups and configurations based on your actual needs.
For more operations about how to create a security group, refer to Virtual Private Cloud (VPC) - Creating a Security Group.
If you want to add rules to a security group, refer to Virtual Private Cloud (VPC) - Security Group - Adding a Security Group Rule.
Elastic IP (optional)
If you want to access the Redis instance over the Internet, you must apply for an Elastic IP (EIP) address.
For operations about how to apply for an EIP, see Purchasing an EIP.
