According to the AWS Shared Responsibility Model, AWS is responsible for the security of the cloud, while the customer is responsible for the security in the cloud. This means that AWS is responsible for protecting the infrastructure that runs AWS services, such as DynamoDB, while the customer is responsible for properly configuring the security of the provided service.For abstracted services, such as DynamoDB, the customer is primarily responsible for managing their data, classifying their assets, and using IAM tools to apply the appropriate permissions12.Therefore, the customer is responsible for controlling the access to DynamoDB tables, such as by creating IAM policies, roles, and users, and using encryption and authentication mechanisms3.Reference:

The concept of granting access only to the resources needed to perform a task is known asleast privilege access. This is a security best practice in IAM that helps to reduce the risk of unauthorized or malicious actions. By applying least privilege access, you can limit the permissions of your IAM users, groups, and roles to the minimum required for their specific tasks. You can also use conditions, permissions boundaries, and IAM Access Analyzer to further restrict and verify access.Reference:Security best practices in IAM,Policies and permissions in IAM,Use IAM policies to grant the least privileges required to access Amazon RDS resources,How to Design a Least Privilege Architecture in AWS,12 Azure & AWS IAM Security Best Practices

Economies of scale are the cost advantages that result from increasing the scale of production or operation. In cloud computing, economies of scale are achieved by pooling resources and sharing them among multiple users, which reduces the unit cost of computing and storage. One of the benefits of economies of scale in cloud computing is increased speed and agility, which means the ability to deploy applications faster and respond to changing business needs more quickly. Cloud computing allows users to access computing resources on demand, without having to invest in expensive infrastructure or wait for lengthy provisioning processes.This enables users to scale up or down as needed, experiment with new ideas, and deliver value to customers faster123.Reference:

AWS Global Accelerator is a service that improves network performance by sending traffic through the AWS worldwide network infrastructure. It uses the AWS global network to direct TCP or UDP traffic to a healthy application endpoint in the closest AWS Region to the client. This provides improvements in terms of latency, throughput, and jitter.Global Accelerator also introduces features such as TCP termination at the edge, jumbo frame support, and large receive side window and TCP buffers to optimize data transfer12. Route table, AWS Transit Gateway, and Amazon VPC are not services or features that improve network performance by sending traffic through the AWS worldwide network infrastructure.Route table is a resource that defines how traffic is routed within a VPC3.AWS Transit Gateway is a service that enables you to connect your VPCs and on-premises networks to a single gateway4.Amazon VPC is a service that lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define5.Reference:Achieve up to 60% better performance for internet traffic with AWS Global Accelerator,Improving Performance on AWS and Hybrid Networks,Route tables,AWS Transit Gateway,Amazon Virtual Private Cloud (VPC)
