Thanks, Danny! I'm preparing to renew my associate certification, and this guide is just what I was looking for. It's a relief to see that the basics haven't changed too much in three years, I haven't missed anything major ;-)
Great article! I'm looking forward to a guide on the DevOps Engineer Exam, Professional Level.
Question 6: How is it that RDS is not just as Multi-AZ-aware as DynamoDB and S3?
And VPCs are also designed to support multi-AZ insofar as a subnet can span multiple AZs, load balancers are multi-AZ, Autoscaling is multi-az, etc.
Is there some nuance I have missed?
DynamoDB and S3 are designed by default to be fault tolerant and use Multi-AZ design principles to accomplish that. All the other services are applicable to be deployed Multi-AZ but by default are deployed in a Single-AZ unless specified otherwise.
Thanks for this article. Could you rank your AWS certs in order of difficulty?
Thanks Danny, the "at least 40 to 50 hours" is for people coming with prior IT knowledge (e.g. software engineers) or is it general?
