Redis instances

Redis is a storage system that supports multiple data structures such as key-value, with the following features.

• support for mixed memory plus disk storage.
• Supports data structures such as String, Hash, List, Set, Sorted Set, and Stream.

Currently, the OneCloud platform already supports managing and creating Redis instances in Alibaba Cloud, Huawei Cloud and Tencent Cloud, and AWS, Azure Redis instances and Tencent Cloud Platform’s cloud cache Memcached only support synchronization for now. Other platforms are being supported in succession.

Using process

1. Create a Redis instance, please see Create Redis Instance for details.
2. If you want to control the IP address of the Redis database, please set up a whitelist, please see Create Whitelist for details.
3. After the system is created, there is only an administrator account. Users can create accounts and set permissions according to their needs, please see Create Account for details.
4. Use the account to connect to the Redis database.
