免费的Redis数据库

做一些小程序要用到数据库,由于Serverless所以不想自建服务器做,就打算借助外力.

提供者:http://redislabs.com/

免费套餐:

  • 只在部分地区提供
  • 30个并发连接
  • 30MB储存

性能测试:

redis-benchmark -h redis-14504.c61.us-east-1-3.ec2.cloud.redislabs.com -p 14504 -a Pldg74aNadkGD6NCsvG3ZaQNUNjouUkk -c 30 -n 500000 -d 32

所以实际性能和网络关系还挺大的,redis本身足够快,但是想获得好的能力,还需要自己网络本身快.
