Using EC2 instances in multiple Availability Zones is an AWS infrastructure solution that meets the requirements of migrating a high performance computing (HPC) application to AWS with fault tolerance and failover capabilities, and with the least latency between components. An Availability Zone is a physically isolated location within an AWS Region that has its own power, cooling, and network connectivity. EC2 instances within the same Region can communicate with each other using low-latency private IP addresses. By using EC2 instances in multiple Availability Zones, the company can achieve fault tolerance and failover for their HPC application, because they can distribute the workload and data across different locations that are independent of each other. If one Availability Zone becomes unavailable or impaired, the company can redirect the traffic and data to another Availability Zone without affecting the performance and availability of the application5

One of the primary advantages of the AWS Cloud is the ability to provision resources on demand. Users no longer need to over-provision or guess the capacity needed for infrastructure, which helps optimize costs and improve agility. AWS handles infrastructure scaling dynamically based on the actual usage. Options B, C, and D are incorrect as users do not maintain sole ownership of IT hardware or control of underlying infrastructure, and while they do maintain some control over the operating system in some cases, it is not an advantage specific to the cloud.

Amazon S3 is the AWS service that offers object storage. Object storage is a technology that stores and manages data in an unstructured format called objects. Each object consists of the data, metadata, and a unique identifier. Object storage is ideal for storing large amounts of unstructured data, such as photos, videos, email, web pages, sensor data, and audio files1. Amazon S3 provides industry-leading scalability, data availability, security, and performance for object storage2.

Amazon RDS is the AWS service that offers relational database storage. Relational database storage is a technology that stores and manages data in a structured format called tables. Each table consists of rows and columns that define the attributes and values of the data. Relational database storage is ideal for storing structured or semi-structured data, such as customer records, inventory, transactions, and analytics3.

Amazon Elastic File System (Amazon EFS) is the AWS service that offers file storage. File storage is a technology that stores and manages data in a hierarchical format called files and folders. Each file consists of the data and metadata, and each folder consists of files or subfolders. File storage is ideal for storing shared data that can be accessed by multiple users or applications, such as home directories, content repositories, media libraries, and configuration files4.

Amazon DynamoDB is the AWS service that offers NoSQL database storage. NoSQL database storage is a technology that stores and manages data in a flexible format called documents or key-value pairs. Each document or key-value pair consists of the data and metadata, and can have different attributes and values depending on the schema. NoSQL database storage is ideal for storing dynamic or unstructured data that requires high performance, scalability, and availability, such as web applications, social media, gaming, and IoT.

AWS Artifact is a service that provides on-demand access to security and compliance reports from AWS and Independent Software Vendors (ISVs) who sell their products on AWS Marketplace. You can use AWS Artifact to download auditor-issued reports, certifications, accreditations, and other third-party attestations of AWS compliance with various standards and regulations, such as PCI-DSS, HIPAA, FedRAMP, GDPR, and more1234. You can also use AWS Artifact to review, accept, and manage your agreements with AWS and apply them to current and future accounts within your organization2. References: 1: Cloud Compliance - Amazon Web Services (AWS), 2: Security Compliance Management - AWS Artifact - AWS, 3: AWS Compliance Contact Us - Amazon Web Services, 4: AWS SECURITY AND COMPLIANCE QUICK REFERENCE GUIDE

AWS Trusted Advisor is a service that provides real-time guidance to help optimize AWS resources, improve security, and maximize performance. It includes a Security category that can identify security group configurations that allow unrestricted access to specific ports. It offers recommendations and alerts to help remediate misconfigurations and ensure proper security practices1. References:

The AWS Pricing Calculator is a web-based tool that allows customers to estimate their monthly AWS costs by configuring and projecting the costs of different AWS services. The calculator is specifically designed to help customers plan their AWS spending based on their specific architecture and usage patterns. The other options are not correct because:

B. Calculate historical AWS costs: This is incorrect as the AWS Pricing Calculator does not track or calculate historical costs. For historical costs, AWS Cost Explorer is used.

C. Provide in-depth information about AWS pricing strategies: While the AWS Pricing Calculator provides cost estimations, it does not provide detailed insights into AWS pricing strategies.

D. Provide users with access to their monthly bills: This is incorrect; AWS Billing and Cost Management provides access to actual billing information.

Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast container management service that allows you to run, stop, and manage Docker containers on a cluster of Amazon EC2 instances or a serverless environment powered by AWS Fargate. It provides secure, reliable, and scalable operations for containers, allowing users to deploy containers in a highly secure and reliable manner. Amazon Aurora is a relational database service, Amazon Athena is an interactive query service, and Amazon Polly is a text-to-speech service. Therefore, the correct answer is Amazon ECS.References:
