有条件的建议申请 Oracle Always Free Arm 机器,评测如图。这机器这配置再其他正规公有云上月费用都得上百刀。
# 一、成本
AWS 韩国:5 美金 Lightsail ,11 块左右(吃码:
my.cloudcpp.com )
Oracle/甲骨文 韩国春川:目前依旧是永久免费。
# 二、配置
AWS 韩国:1 核 1G 内存 2TB 流量
Oracle/甲骨文 韩国春川:4 核 24GB 内存 10TB 流量
# 三、利用
AWS 韩国:做前端服务器,比如说 Nginx ,Haproxy ,支持零拷贝的 moto 等等。其对全国大部分地区都非常友好,特别是联通,非常适合跑流量和网站。
Oracle/甲骨文 韩国春川:做后端服务器,比如说 MySQL ,WordPress ,K8S ,Apache ,ClickHouse 等,其单核主频高达 3GHz 。
# 四、CPU 跑分对比
这里主要采用 Geekbench 5 跑分。甲骨文 ARM 得益于主频较高,且均为真实核心无超线程撕裂核心,拉出传统 x86 CPU 一大截,非常适合跑高负载应用。

# 六、备份
当然是用异地增量备份了,重要的数据建议每小时备份一次,不重要的数据建议每天备份一次。即能做站,也能做开发,机器性能和机器性价比非常的高。
