Service discovery in loose coupling refers to using DNS names or service endpoints rather than hardcoded IP addresses. This allows services to be dynamically located and accessed without clients knowing their exact IP addresses, enabling infrastructure flexibility.

IAM users access the AWS Management Console through a unique sign-in URL that includes the AWS account ID: https://AWSAccountID.signin.aws.amazon.com/console. This is different from the root account URL.

Provisioned IOPS SSD (IO1) volumes are designed for applications requiring consistent, high I/O performance like NoSQL databases. They provide guaranteed IOPS rates and low latency, unlike HDD volumes which are better for sequential access.

AWS Direct Connect provides a dedicated network connection from your premises to AWS. It supports speeds of 1Gbps, 10Gbps, and higher.

The IAM console provides a 'Last activity' column for users, which displays the date and time of the last AWS service request made by that user. This helps administrators identify inactive accounts.

RDS automated backups are free up to 100% of your total database storage size. If you exceed this, you are charged for the additional storage.

Yes, on-premises servers can access Amazon EFS using AWS Direct Connect or a VPN connection, allowing for hybrid file storage solutions.

IAM policies are defined using JSON (JavaScript Object Notation) format to specify permissions for users, groups, and roles.

The AWS Simple Monthly Calculator was the legacy tool for estimating costs, though it has been largely superseded by the AWS Pricing Calculator.

You can install database software (like MySQL or PostgreSQL) on an EC2 instance to host a relational database, though you would be responsible for managing the OS and database software.

The AWS Personal Health Dashboard provides alerts and remediation guidance for AWS events that specifically impact your resources.

EC2 key pairs are region-specific. If you create a key pair in one region, it cannot be used to launch instances in another region.

AWS allows customers to perform security assessments and penetration testing on their own instances, provided they follow the AWS Penetration Testing Policy.

Amazon S3 is an object storage service, which stores data as objects within buckets, rather than as blocks or files.

Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS.

AWS pricing philosophy includes 'pay as you go', 'pay less when you reserve', and 'pay even less as AWS grows' (economies of scale). 'Pay less when you consume less' is not a formal pricing pillar.
