Study Notes

AWS Services and Tools

AWS Auto Scaling: Automatically adjusts the number of Amazon EC2 instances based on application needs, optimizing costs by selecting the most cost-effective EC2 instances. Used to respond to changing demand.
AWS Compute Optimizer: Provides recommendations for right-sizing Amazon EC2 instances based on historical workload data, analyzing instance configurations and performance. Helps improve performance, reduce costs, and eliminate underutilized resources.
AWS Cost Explorer: Used to analyze and visualize cost and usage data in the AWS account. Not for responding to demand changes.
AWS Well-Architected Framework: A framework for designing secure, reliable, efficient, and cost-effective cloud architectures. Not a service or tool for responding to demand changes.

AWS Database Services

Amazon RDS (Relational Database Service): A managed service that simplifies the setup, operation, and scaling of MySQL and other databases in the AWS cloud. Handles routine tasks like provisioning, patching, backups, recovery, and scaling.

Cloud Concepts

Reliability: Configuring automatic failover between AWS Regions.

AWS Compliance

AWS Artifact: Provides access to AWS compliance reports, agreements, and security standards documentation.

Data Analysis Services

Amazon Athena: An interactive query service for analyzing data stored in Amazon S3 using SQL, handling various formats including .csv, with minimal operational overhead.

AWS Account Management

AWS Organizations: Enables consolidation of multiple AWS accounts into one managed organization, managing groups of accounts with policies (Service Control Policies - SCPs). Facilitates consolidated billing.

Messaging Services

Amazon Simple Notification Service (SNS): A fully managed pub/sub messaging service used to send messages (text and email) from distributed applications to multiple endpoints.

Cloud Architecture

Decoupling: Improves the ability to upgrade components independently.

Cost Optimization

Right-sizing services: Choosing the most appropriate AWS resources for application needs, to avoid over- or under-provisioning.
Cost allocation tags: For tracking infrastructure costs for different projects. Allows categorization of resources for billing purposes and doesn't impact existing infrastructure.

AWS Services for Applications

Amazon AppStream 2.0: Allows deployment of applications without backend infrastructure investments. Suitable for applications that require robust hardware but must be accessible via lightweight, low-cost client devices (e.g., student laptops).

AWS Compute Capacity

Spot Instances: Flexible pricing for EC2 instances (up to 90% discount). Ideal for stateless, fault-tolerant workloads that can run up to 3 hours.
Reserved Instances (RI): Reserved EC2 instances for a specific period (1 or 3 years), with a lower hourly rate. Suitable for steady-state or predictable workloads.
On-Demand Instances: Standard fixed hourly rate for EC2 instances. Suitable for short-term or irregular workloads.
Dedicated Instances: EC2 instances running on dedicated hardware. Useful for workloads needing regulatory compliance or data isolation.

Accessing AWS Compliance

AWS Artifact: Allows companies to access AWS compliance documentation (e.g., audit reports, certifications) for compliance with industry standards and regulations like PCI.

Site-to-Site VPN

Virtual Private Gateway: AWS side of the VPN connection.
Customer Gateway: Customer's side of the VPN connection.
