Benefits

Stable & Available

Incorporating an independent disaster recovery mechanism, which can improve the reliability of data with the help of system images and snapshots. Providing service availability up to 99.95%, and data reliability up to 99.99999%.

Flexible Control Over Cost

Support the creation of multiple instances in minutes, quickly provides flexible scaling according to actual business situations. Offering purchase on demand, pay-as-you-go billing, control cost with flexibility.

Secure & Reliable

Providing basic security protection features such as host firewall, network firewall, host resource monitoring and failure alerts free of charge; each tenant can customize their private network and completely isolate resources; security detection tools and operation logs for cloud servers are also provided.

Deployed in Seconds with Simple Scalability

Deploy a single cloud server in seconds and supporting customized batch-scale deployment of an image. The same image can quickly replicate the environment in multiple cloud servers to rapidly establish and expand capacity.

    • The security group functions as the whitelist firewall for the egress and ingress traffic of the virtual network card on the cloud server, security group rules in the list allow appropriate traffic to pass through.
    • Established data centers (T3 and above), robust and highly availability network architecture, advanced virtualization technology, comprehensive hardware equipment and monitoring and alert system to ensure the stable operation of cloud servers.
  • Monitoring Service

    Provide comprehensive cloud monitoring services, including resource information monitoring, alert, notification and other services.

    • Monitoring overview: display an overview of cloud resource instances on the Dashboard screen, and view the monitoring data including CPU utilization, memory utilization and other dimensions to quickly determine resource usage.
    • Flexible alerts: customize alert rules combined with alert template, and send instant alert notification of failure by setting trigger granularity, threshold, etc.

Scenarios

  • Website/Mobile APP
  • Mass Traffic Applications
  • At the initial stages of building a website, users may choose a low-spec cloud server to put applications, files and other resources on the same cloud server.

  • Adjust the configuration and number of cloud servers at any time according to the changes in the number of visitors, and easily cope with the growth and any concurrencies of the website business.

  • For image and video websites/applications, cloud servers will provide front-end access with Wangsu object storage, to facilitate storage of massive image and video files.

  • Combining Wangsu CDN and cloud scheduling service to support traffic load and nearby distribution, greatly improve user access experience, reduce bandwidth usage and save cost.
