For a reporting application that runs only periodically, On-Demand Instances are the most cost-effective choice because they allow the company to pay only for the compute capacity used, without long-term commitments. Reserved Instances are less flexible due to the need for upfront payment or long-term contracts, which would not be cost-effective given the application’s intermittent usage. On-Demand Capacity Reservations would also be more costly, as they hold capacity regardless of usage.

Amazon RDS (Relational Database Service) supports SQL Server and other relational databases while handling administrative tasks such as backups, patching, monitoring, and scaling. This allows the company to migrate its SQL Server database without managing the infrastructure manually. Amazon EC2for SQL Server would require more administrative overhead, as the company would be responsible for the maintenance. Amazon DynamoDB and Aurora do not support SQL Server directly.

AWS CloudFormation allows developers to create, manage, and deploy AWS resources using templates, ensuring a standardized and repeatable infrastructure setup. It’s ideal for setting up development, test, and production environments consistently. AWS Cloud Map, CloudFront, and CloudTrail do not provide templated infrastructure management capabilities.

AWS Snowball Edge is designed for large-scale data transfer tasks, allowing companies to transport significant amounts of data (up to petabytes) from their data centers to AWS without relying on the internet. With the ability to transfer 100 TB of data securely and efficiently, Snowball Edge is the ideal choice for this use case. AWS Snowcone is for smaller transfers, and AWS Data Exchange and DataSync are not designed for physical data transport.

The AWS Cloud's global infrastructure enables rapid deployment across multiple geographic regions, allowing companies to extend applications to new markets quickly. This capability to "go global in minutes" is especially valuable for businesses looking to reach customers in new countries without building data centers. Other options, like speed and agility, are advantages but do not specifically address global deployment.

Amazon CloudFront is a content delivery network (CDN) that uses edge locations to cache content closer to users, reducing latency and improving performance. It supports the delivery of web content, such as videos and images, by caching copies at edge locations around the world. Amazon Kinesis, SQS, and Route 53 do not utilize edge locations for content caching.

Using multiple Availability Zones within the same AWS Region meets the requirements for having instances in different locations with independent power and networking. Availability Zones are distinct physical locations within a region, each with separate power sources and networking. Edge locations are used for content delivery, and Amazon Connect and AWS Artifact locations are not relevant to EC2 deployment and infrastructure.

Amazon Route 53 is a scalable Domain Name System (DNS) web service that routes end-user requests to infrastructure running in AWS. It is specifically designed to host domain names and manage DNS records, making it the ideal service for hosting the domain name of a public website. AWS Lambda, CloudFront, and Direct Connect serve different functions and are not DNS hosting services.

Amazon CloudWatch alarm is an AWS service or feature that can initiate an Amazon EC2 Auto Scaling action based on CPU utilization. Amazon CloudWatch is a monitoring and observability service that collects and tracks metrics, logs, events, and alarms for your AWS resources and applications. Amazon CloudWatch alarms are actions that you can configure to send notifications or automatically make changes to the resources you are monitoring based on rules that you define67.

Amazon EC2 Auto Scaling is a service that helps you maintain application availability and allows you to automatically add or remove EC2 instances according to definable conditions. You can create dynamic scaling policies that track a specific CloudWatch metric, such as CPU utilization, and define what action to take when the associated CloudWatch alarm is in ALARM. When the policy is in effect, Amazon EC2 Auto Scaling adjusts the group’s desired capacity up or down when the threshold of an alarm is breached89. References: 6: Cloud Monitoring - Amazon CloudWatch - AWS, 7: Amazon CloudWatch Documentation, 8: Dynamic scaling for Amazon EC2 Auto Scaling, 9: Amazon EC2 Auto Scaling Documentation

AWS Pricing Calculator and AWS Application Discovery Service are the best combination of AWS services or tools to meet the requirements of determining the total cost of ownership for compute resources that will be hosted on the AWS Cloud. AWS Pricing Calculator is a tool that enables you to estimate the cost of using AWS services based on your usage scenarios and requirements. You can use AWS Pricing Calculator to compare the costs of running your applications on-premises or on AWS, and to optimize your AWS spending. AWS Application Discovery Service is a service that helps you plan your migration to the AWS Cloud by collecting and analyzing information about your on-premises servers, applications, and dependencies. You can use AWS Application Discovery Service to identify the inventory of your on-premises infrastructure, group servers by applications, and estimate the performance and resource utilization of your applications45

AWS VPN and AWS Direct Connect are two services that enable customers to connect their on-premises data center network to the AWS Cloud. AWS VPN establishes a secure and encrypted connection over the public internet, while AWS Direct Connect establishes a dedicated and private connection through a partner network.
