Amazon Aurora is a fully managed MySQL-compatible database that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open-source databases. Amazon Aurora is part of the Amazon Relational Database Service (Amazon RDS) family, which means it inherits the benefits of a fully managed service, such as automated backups, patches, scaling, monitoring, and security. Amazon Aurora also offers up to five times the throughput of standard MySQL, as well as high availability, durability, and fault tolerance with up to 15 read replicas, cross-Region replication, and self-healing storage. Amazon Aurora is compatible with the latest versions of MySQL, as well as PostgreSQL, and supports various features and integrations that enhance its functionality and usability123

AWS Migration Hub assists users in planning and tracking the progress of their server and application migrations. It centralizes migration tracking across various AWS services, providing visibility into application inventory and migration status. While AWS Application Migration Service also assists with migrations, Migration Hub is specifically designed for tracking migration data comprehensively.

The AWS account root user is the email address that you used to sign up for AWS. The root user has complete access to all AWS services and resources in the account. You should use the root user only to perform a few account and service management tasks. One of these tasks is changing AWS Support plans, which requires root user credentials. For other tasks, you should create an IAM user or role with the appropriate permissions and use that instead of the root user.

According to the AWS shared responsibility model, the customer is responsible for the security in the cloud, which includes configuring firewalls and networks. AWS provides security groups and network access control lists (NACLs) as firewall features that customers can use to control the traffic to and from their AWS resources. Customers are also responsible for managing their own virtual private clouds (VPCs), subnets, route tables, internet gateways, and other network components. AWS is responsible for the security of the cloud, which includes the physical security of the facilities, the host operating system and virtualization layer, and the AWS global network infrastructure12. References:

 This is a design principle of the operational excellence pillar of the AWS Well-Architected Framework. Performing operations as code means using scripts, templates, or automation tools to perform routine tasks, such as provisioning, configuration, deployment, and monitoring. This reduces human error, increases consistency, and enables faster recovery from failures. You can learn more about the operational excellence pillar from this whitepaper or this digital course.

Using multiple Availability Zones within the same AWS Region meets the requirements for having instances in different locations with independent power and networking. Availability Zones are distinct physical locations within a region, each with separate power sources and networking. Edge locations are used for content delivery, and Amazon Connect and AWS Artifact locations are not relevant to EC2 deployment and infrastructure.

The AWS Cloud is cost-effective for dynamic workloads because of its elasticity, allowing resources to scale up or down based on demand, and its pay-as-you-go pricing, which enables companies to pay only for what they use. Reliability, security, and high availability are also benefits of AWS, but they do not specifically relate to cost-effectiveness in the context of dynamic workloads.

AWS Organizations is an AWS service that enables you to centrally manage and govern your AWS Cloud environments across multiple business units. AWS Organizations allows you to create an organization that consists of AWS accounts that you create or invite to join. You can group your accounts into organizational units (OUs) and apply service control policies (SCPs) to them. SCPs are a type of policy that specify the maximum permissions for the accounts in your organization, and can help you enforce compliance and security requirements. AWS Organizations also simplifies billing processes by enabling you to consolidate and pay for all member accounts with a single payment method. You can also use AWS Organizations to automate the creation of AWS accounts by using APIs or AWS CloudFormation templates. References: What is AWS Organizations?, Policy-Based Management - AWS Organizations
