Exam AWS Certified Solutions Architect - Professional topic 1 question 491 discussion

D A: Cloudwatch does not provide cost-savings suggestions. B: You don’t need to use 3rd party application. You can use AWS trusted adviser or cost explorer which comes free. C: Reserved instances may not help if you cannot even decide which instance to use. D: You do not need Business support to check have cost saving suggestions. But since this is the only open that has Trusted Advisor, I chose this.

Question is to optimize CURRENT workload, NOT re-platform software. A: Best choice without completely rebuilding environment B: Issues with using CodeDeploy to configure EC2s aside, AWS will NEVER recommend you buy a 3rd party app to analyze usage--AWS has tools for this C: Only a suicidal buffoon would make monthly meetings part of an architecture workflow. Absolutely not. Beanstalk is a maybe, but the end of this answer absolutely rules it out. D: Again, this answer re-platforms (re-architects?) the software, it doesn't optimize the CURRENT workload, which is what the questions asked for. Also, anyone with experience using Business Support and Trusted Advisor will know that the TA utilization checks are not as good as custom cloudwatch metrics. While this answer is tempting because it gets off EC2 and uses a managed service for utilization analysis, I don't think it answers the original question and I don't think upgrading to business support is a good recommendation for a workload improvement.

D. Workload, IMHO, refers to the work for team periodically evaluate the utilization of the instance types. ECS minimize service impact on current running solution, and Trusted Advisor simply provide cost saving tips (with regards to right EC2 instance type)

This is a really old question and the answer WAS A, but CloudFormer is already deprecated, the next answer that makes more sense is D.

"Enough Amazon EC2 instances to satisfy peak demand" > autoscaling is obvious optimization

Answer: D Why NOT A: In Vertical scaling, only automatic option is to shutdown EC2 instance. Manually, CloudWatch will generate a lot of Alarms almost hourly … The best solution is Horizontal scaling. https://aws.amazon.com/about-aws/whats-new/2013/01/08/use-amazon-cloudwatch-to-detect-and-shut-down-unused-amazon-ec2-instances/

D. Deploy the application as a Docker image by using Amazon ECS. Set up Amazon EC2 Auto Scaling and Amazon ECS scaling. Register for AWS Business Support and use Trusted Advisor checks to provide suggestions on cost savings.

D is right based on statement "The team must conduct frequent evaluations of the instance types' use to ensure that the appropriate sizes are deployed".

D. Workload, IMHO, refers to the work for team periodically evaluate the utilization of the instance types. ECS minimize service impact on current running solution, and Trusted Advisor simply provide cost saving tips (with regards to right EC2 instance type)

Ill choose D over A, since cloudformer is deprecated and CW doesn't do cost savings suggestions

AAA ---

I think maybe D because with microservices Docker in this case the utilization is more fine grained. And also the Trust Advisor is a good tool. Also CloudFormer seems to be discontinued.

I don't understand this question/the options..

A https://aws.amazon.com/about-aws/whats-new/2013/01/08/use-amazon-cloudwatch-to-detect-and-shut-down-unused-amazon-ec2-instances/

I'll go with D

this is weird question ever encounter, by choice will be A

Inclined to choose A since optimisation is the key but cloudformer has deprecated so going with D instead
