Explanation

https://docs.cloud.oracle.com/iaas/Content/Compute/References/bestpracticescompute.htm System Resilience Oracle Cloud Infrastructure runs on Oracle's high-quality Sun servers. However, any hardware can experience a failure. Follow industry-wide hardware failure best practices to ensure the resilience of your solution. Some best practices include: Design your system with redundant compute nodes in different availability domains to support fail-over capability. Create a custom image of your system drive each time you change the image. Back up your data drives, or sync to spare drives, regularly. If you experience a hardware failure and have followed these practices, you can terminate the failed instance, launch your custom image to create a new instance, and then apply the backup data.
