AWS Monitoring and Deployment Instruments
To sustain cloud systems, deployment, and monitoring are essential. Be prepared to be asked:
- How can infrastructure provisioning be automated in AWS?
- How is AWS Cloud Formation different from Terraform, and what is it?
- Which services offered by AWS support logging and real-time monitoring?
For optimal system dependability, demonstrate your proficiency with tools like AWS Cloud Watch, AWS Config, and auto-scaling techniques.
