Exam1-Part5 Flashcards
EFS lifecycle management Tip
EFS lifecycle management doesn’t delete objects. It can only transition files in and out of the “Infrequent Access” tier.
IAM database authentication
a feature provided by Amazon Web Services (AWS) that allows you to authenticate to your Amazon Relational Database Service (RDS) instances using AWS Identity and Access Management (IAM) credentials instead of traditional database credentials. It provides a more secure and centralized approach to manage database access and authentication.
SQS Tip
Always remember that the messages in the SQS queue will continue to exist even after the EC2 instance has processed it, until you delete that message. You have to ensure that you delete the message after processing to prevent the message from being received and processed again
AWS Key Management Service (KMS) custom key store feature
It is an advanced capability that allows you to securely store your KMS keys in a hardware security module (HSM) that you own and manage.
The Custom Key Store feature integrates your HSM with the KMS service. It establishes a secure connection between your HSM and the KMS service in AWS, enabling you to use your HSM to generate, manage, and protect your KMS keys.
AWS Database Migration Service (DMS)
AWS DMS is a fully managed service that simplifies database migration to AWS. It supports both homogenous (e.g., Oracle to Oracle) and heterogeneous (e.g., Microsoft SQL Server to Amazon Aurora) migrations. DMS handles schema conversion, data replication, and ongoing replication for continuous data synchronization.
RPO & RTO with Aurora
Aurora Global Database supports storage-based replication that has a latency of less than 1 second. If there is an unplanned outage, one of the secondary regions you assigned can be promoted to read and write capabilities in less than 1 minute. This feature is called Cross-Region Disaster Recovery. An RPO of 1 second and an RTO of less than 1 minute provide you a strong foundation for a global business continuity plan.
RDS events
RDS events only provide operational events such as DB instance events, DB parameter group events, DB security group events, and DB snapshot events. capturing data-modifying events (INSERT, DELETE, UPDATE) can be achieved thru native functions or stored procedures.
DynamoDB stream
A DynamoDB stream is an ordered flow of information about changes to items in an Amazon DynamoDB table. When you enable a stream on a table, DynamoDB captures information about every modification to data items in the table.
