A company implements a web farm with 100 servers behind an application load balancer. Dunng scaling events, new web servers that are placed in service have not loaded all their modules, which causes some requests to the web farm to fail.
Which of the following should the cloud engineer implement to address the scaling issue?
- Instance warm-up
- Scheduled scaling
- Event-based scaling
- Load balancer passthrough
Answer(s): A
Explanation:
Implementing an instance warm-up period can address the issue of new web servers not having all modules loaded during scaling events. This warm-up period allows new instances to fully initialize and start serving traffic only when they are ready, preventing failed requests.
Reference:
Scaling strategies and their operational impact, including the concept of instance warm- up, are covered under cloud infrastructure management in the CompTIA Cloud+ curriculum.
