The ability to scale resources up and down based on application load is tied to the advantage of "Stop guessing capacity." This feature allows users to scale resources automatically to match the demand, thereby avoiding over-provisioning or under-provisioning of resources. "Go global in minutes," "Benefit from massive economies of scale," and "Trade fixed expense for variable expense" are other advantages of cloud computing, but they do not specifically address scaling resources up and down based on load.

EC2 Instance Savings Plans are a flexible pricing model that offer discounted hourly rates on Amazon EC2 instance usage for a 1 or 3 year term. EC2 Instance Savings Plans provide savings up to 72% off On-Demand rates, in exchange for a commitment to a specific instance family in a chosen AWS Region (for example, M5 in Virginia). These plans automatically apply to usage regardless of size (for example, m5.xlarge, m5.2xlarge, etc.), OS (for example, Windows, Linux, etc.), and tenancy (Host, Dedicated, Default) within the specified family in a Region. With an EC2Instance Savings Plan, you can change your instance size within the instance family (for example, from c5.xlarge to c5.2xlarge) or the operating system (for example, from Windows to Linux), or move from Dedicated tenancy to Default and continue to receive the discounted rate provided by your EC2 Instance Savings Plan4567. References: 4: Compute Savings Plans – Amazon Web Services, 5: What are Savings Plans? - Savings Plans, 6: How To Cut Your AWS Bill With Savings Plans (and avoid some common …, 7: AWS Savings Plans vs Reserved Instances - GorillaStack

AWS Artifact is a service provided by AWS that offers on-demand access to AWS compliance reports, including the Payment Card Industry (PCI) reports. It is the primary tool for retrieving compliance reports such as Service Organization Control (SOC) reports, ISO certifications, and Payment Card Industry Data Security Standard (PCI DSS) reports.

To obtain these reports:

The company should log into the AWS Management Console and navigate to AWS Artifact.

From there, they can select and download the necessary compliance reports.

Why other options are not suitable:

A. Contact AWS Support: AWS Support is not needed to obtain these reports; they are readily available through AWS Artifact.

C. Download reports from AWS Security Hub: AWS Security Hub is a service that provides a comprehensive view of security alerts and compliance status, but it does not host or provide compliance reports like PCI DSS.

D. Contact an AWS technical account manager (TAM): While a TAM may assist in various AWS-related queries, they are not required to obtain PCI reports. AWS Artifact is designed for this purpose.

Amazon GuardDutyis a threat detection service that continuously monitors AWS accounts and workloads for malicious activity and unauthorized behavior to help protect your AWS resources.

B. AWS WAF: Incorrect, as it is a web application firewall that protects against common web exploits but does not provide comprehensive threat detection.

C. AWS Shield: Incorrect, as it provides protection against DDoS attacks but does not detect compromises within AWS accounts.

D. Amazon Inspector: Incorrect, as it is a service that helps improve the security and compliance of applications deployed on AWS by assessing for vulnerabilities, not for threat detection.
