Third-party storage - Seven cattle cloud

Seven cattle introduced cloud

• The initial project, a small amount of data, the general will use a third-party storage solutions, the cost is relatively low, but also safe and reliable
• When the data reaches a certain size, the cost of third-party storage of more than build their own service file, the file will choose to build their own service system
• Object storage service OSS
• Details
  • Requirements Verified
  • Create storage space
  • The default domain name to generate test is valid for one month is required for long-term use to bind your own domain name
