避免传统的补丁程序重启是破坏性的,造成停机时间,造成延误

Security Update Released

1. System administrator negotiates with management to schedule outage windows

2. System administrator schedules downtime the following week

3. System administrator notifies users of planned downtime

…And Another 4 Hours Later

1. Updates applied and tested

2. Back in business after first notification of security update - typically over one week has passed

1. Shut down application server

2. Shut down database

3. Apply Linux OS update

4. Start up database

5. Start up application server

6. Sanity check application

…One Week Later
