Amazon DynamoDB is a global AWS service. It automatically replicates data across multiple AWS regions, providing high availability and durability, and enabling low-latency data access even at scale.
Amazon Route 53 is a scalable DNS web service that allows you to route end users to different AWS regions where your applications are hosted, enabling deployment across multiple regions.
In AWS's shared responsibility model, AWS manages the security of the cloud infrastructure, while the customer is responsible for security in the cloud. This includes managing their data, identity and access management, and configuring security features like encryption and network firewalls.
To ensure high availability in AWS, it is essential to design your architectures using multiple Availability Zones. This strategy allows resilience to failures in individual zones by distributing resources across isolated locations, ensuring your application remains available even if one zone goes down. Option 2 is the correct choice for achieving high availability.
AWS Trusted Advisor is the service that provides recommendations to help improve resource efficiency, security, cost optimization, and performance. It analyzes your AWS environment and identifies ways to optimize your service usage. Option 2 (AWS Cost Explorer) primarily focuses on cost management, while option 3 (AWS Support Plan) provides support services, not specific recommendations for cost and performance improvements.
Amazon RDS (Relational Database Service) is a managed service that makes it easy to set up, operate, and scale a relational database in the cloud. It supports several database engines and automates common administrative tasks.
AWS CodeDeploy is a deployment service that automates application deployments to various compute services such as Amazon EC2, AWS Lambda, and on-premises servers. It helps to manage and automate the deployment process, ensuring consistent and safe updates across your application infrastructure.
AWS Organizations is a service that enables you to create and manage multiple AWS accounts within a central organization. It allows for the streamlined management of different environments, such as development, testing, and production. You can use AWS Organizations to apply policies, consolidate billing, and organize resources based on the stage of development.
The AWS Key Management Service (KMS) is specifically designed to create and manage cryptographic keys and control their use across a wide range of AWS services and in your applications. AWS KMS is the primary service that stores and manages encryption keys securely within AWS. On the other hand, AWS Certificate Manager deals primarily with SSL/TLS certificates, and AWS CloudHSM provides hardware-based key storage for more stringent compliance requirements.
Amazon SQS (Simple Queue Service) is suitable for decoupling and scaling microservices. It allows you to send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available. It's an effective way to decouple and scale distributed systems and microservices architectures.
