The correct answer is D. Platform.

The Platform perspective in the AWS Cloud Adoption Framework (AWS CAF) includes a capability for well-designed data and analytics architecture. This capability helps you design, implement, and optimize your data and analytics solutions on AWS, using services such as Amazon S3, Amazon Redshift, Amazon EMR, Amazon Kinesis, Amazon Athena, and Amazon QuickSight. A well-designed data and analytics architecture enables you to collect, store, process, analyze, and visualize data from various sources, and derive insights that can drive your business decisions12.

The Security perspective does not include a capability for data and analytics architecture, but it does include a capability for data protection, which helps you secure your data at rest and in transit using encryption, key management, access control, and auditing13.

The Governance perspective does not include a capability for data and analytics architecture, but it does include a capability for data governance, which helps you manage the quality, availability, usability, integrity, and security of your data assets14.

The Operations perspective does not include a capability for data and analytics architecture, but it does include a capability for data operations, which helps you monitor, troubleshoot, and optimize the performance and availability of your data pipelines and workloads1 .

This is the AWS service or resource that will meet the requirements of distributing traffic between the Amazon EC2 instances that host the website. Application Load Balancer is a type of Elastic Load Balancing that distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. Application Load Balancer operates at the application layer (layer 7) of the OSI model and supports advanced features such as path-based routing, host-based routing, health checks, and SSL termination. You can learn more about Application Load Balancer from [this webpage] or [this digital course].

Savings Plans offer cost savings for predictable, steady workloads over a one or three-year term, with flexibility in instance family and size, making them suitable for critical workloads on EC2 instances that will run for a long term like three years. Spot Instances are more cost-effective but not suitable for critical, predictable workloads due to potential interruptions. Dedicated Hosts and On-Demand Instances would be more costly.

Understanding High Availability: High availability (HA) refers to systems that are durable and likely to operate continuously without failure for a long time. HA ensures that an architecture can withstand failures with minimal downtime.

Importance of High Availability:

Redundancy: Systems are designed with redundancy to prevent single points of failure.

Fault Tolerance: Ensures that failures do not result in significant downtime, maintaining service continuity.

Automated Recovery: Utilizes automated recovery mechanisms to quickly restore services in the event of a failure.

AWS Services for High Availability:

Multi-AZ Deployments: Services like RDS, DynamoDB, and others support Multi-AZ deployments for fault tolerance.

Elastic Load Balancing: Distributes traffic across multiple instances or availability zones to ensure no single point of failure.

Auto Scaling: Automatically adjusts the number of instances based on demand, ensuring availability even during traffic spikes.
