Study Notes

AWS CLI and Tag Management

Use the delete-tags command to remove tags from an Amazon Elastic File System.
Tags consist of a key-value pair used to label AWS resources like EBS file systems.
If an invalid key tag is provided during deletion, no error occurs.

Amazon S3 Bucket Naming Rules

Bucket names must be unique across all AWS accounts; they cannot be duplicated.
Bucket names cannot contain uppercase letters or underscores.
Once a bucket is created, its name cannot be changed.
Bucket names must start with a lowercase letter or number and be between 3 to 63 characters in length.
Avoid creating bucket names that resemble IP addresses.

AWS Services for Application Migration

Amazon ElastiCache supports data stores for on-premise applications migrating to AWS and is ideal for session management.
It offers two caching options: Memcached and Redis, both of which are scalable and support in-memory data management.

Elastic Beanstalk for Application Deployment

Elastic Beanstalk provides a platform for deploying applications and managing backend resources efficiently.
Key features include automatic load balancing, application monitoring, scaling, and capacity provisioning without control limitations.

Data Migration to AWS

AWS Redshift is recommended for transferring large volumes of data (terabytes to petabytes) from on-premise environments to the cloud.
It operates as a fully functional data warehousing solution with SQL support for complex queries.

Amazon Glacier Data Retrieval

The expedited retrieval option allows access to archived data within one to five minutes.
Retrieval duration can vary based on data size; for data over 250MB, expect one to five minutes.
Two retrieval types are available: on-demand and provisioned.

Monitoring AWS Resources

AWS Trusted Advisor monitors resource limits such as EBS volumes, snapshots, and Elastic IP addresses.
It provides recommendations for cost reduction, performance enhancement, and security risk mitigation within AWS environments.
