AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards AWS applications against network and transport layer attacks. AWS Shield Standard is automatically included with all AWS services and offers protection against common DDoS attacks. For more advanced protection, AWS Shield Advanced provides additional DDoS mitigation measures. Although AWS WAF, Firewall Manager, and GuardDuty contribute to security, they do not specialize in DDoS mitigation at the network layer like AWS Shield does.

Agility is the AWS Cloud benefit that gives a company the ability to quickly deploy cloud resources to access compute, storage, and database infrastructures in a matter of minutes. Agility means that you can reduce the time to make IT resources available to your developers from weeks to just minutes, resulting in a dramatic increase in innovation and responsiveness1. AWS provides a range of services and tools that enable you to launch, scale, and manage your cloud applications with ease and speed, such as AWS CloudFormation, AWS Elastic Beanstalk, AWS CodeDeploy, and AWS Quick Starts2345. References:

AWS Organizations is the AWS service or feature that allows users to create new AWS accounts, group multiple accounts to organize workflows, and apply policies to groups of accounts. AWS Organizations enables users to centrally manage and govern their AWS environment across multiple accounts. Users can create organizational units (OUs) to group accounts based on their business needs, such as by function, project, or region. Users can also apply service control policies (SCPs) toOUs or individual accounts to define the permissions and restrictions for the AWS services and resources that they can access. AWS Organizations also offers features such as consolidated billing, account creation automation, and trusted access12. References:

AWS Cloud Development Kit (AWS CDK) is an open source software development framework that allows you to model and provision your cloud infrastructure using familiar programming languages such as TypeScript, Python, Java, and .NET. AWS CDK enables you to use the expressive power of your favorite language to define your cloud resources, such as compute, storage, network, and application services. AWS CDK also provides a library of high-level constructs that represent AWS services and best practices. AWS CDK uses AWS CloudFormation in the background to deploy your resources in a safe and repeatable manner12. References:

Amazon S3 is a service that provides durable storage for static content and infinitely scalable data storage infrastructure at the lowest cost. Amazon S3 is an object storage service that allows you to store and retrieve any amount of data from anywhere on the internet. Amazon S3 offers industry-leading scalability, availability, and performance, as well as 99.999999999% (11 9s) of durability and multi-AZ resilience. Amazon S3 also provides various storage classes that offer different levels of performance and cost optimization, such as S3 Standard, S3 Intelligent-Tiering, S3 Standard-Infrequent Access (S3 Standard-IA), S3 One Zone-Infrequent Access (S3One Zone-IA), and S3 Glacier456. Amazon S3 is ideal for storing static content, such as images, videos, documents, and web pages, as well as building data lakes, backup and archive solutions, big data analytics, and machine learning applications456. References: 4: Cloud Storage on AWS, 5: Object Storage - Amazon Simple Storage Service (S3) - AWS, 6: Amazon S3 Documentation

To meet the goals for sustainability impact, the company should follow the best practices of scaling infrastructure with user load and eliminating creation and maintenance of unused assets. Scalinginfrastructure with user load means adjusting the capacity of the infrastructure to match the demand of the users, which can reduce the energy consumption and carbon footprint of the system. Eliminating creation and maintenance of unused assets means avoiding the waste of resources and money on assets that are not needed or used, which can also improve the environmental and economic efficiency of the system3.

Amazon Simple Queue Service (Amazon SQS) and AWS Step Functions are AWS services that can be used to achieve a loosely coupled architecture. Amazon SQS is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. AWS Step Functions lets you coordinate multiple AWS services into serverless workflows so you can build and update apps quickly. Using Step Functions, you can design and run workflows that stitch together services such as AWS Lambda and Amazon SNS into feature-rich applications. References: Amazon SQS, AWS Step Functions

Understanding AWS Compute Optimizer: AWS Compute Optimizer is a service that analyzes the configuration and utilization metrics of your AWS resources. It provides recommendations to help you select the optimal configurations for your workloads.

Why AWS Compute Optimizer for Rightsizing:

Resource Recommendations: It provides specific recommendations to rightsize your EC2 instances by suggesting instance types that match your actual usage patterns.

Cost Efficiency: By optimizing instance sizes, you can reduce costs associated with over-provisioned resources.

Performance Improvement: Ensures that you are using instances that provide the required performance without over-allocating resources.

How to Implement AWS Compute Optimizer:

Enable AWS Compute Optimizer: In the AWS Management Console, navigate to AWS Compute Optimizer and enable it for your account.

Review Recommendations: After a period of monitoring, review the recommendations provided for your EC2 instances.

Implement Changes: Follow the suggestions to resize or change instance types based on the recommendations, ensuring you balance cost savings with performance needs.
