Study Notes
Data Transfer Charges
- Moving data from an EC2 instance to an S3 bucket in the same region incurs charges for both outbound and inbound data transfer
- The company would be charged for both the outbound data transfer from the EC2 instance and the inbound data transfer to the S3 bucket.
AWS Storage Services
- Storage services offered by AWS Cloud include EFS and S3.
AWS Web Application Firewall (WAF)
- WAF protects from common web exploits at Layer 7.
AWS Shared Responsibility Model
- Replacing faulty Amazon EC2 hardware is an AWS responsibility
- Maintaining Amazon S3 data in different availability zones to keep it durable is an AWS responsibility
DDoS Attack Mitigation
- Amazon CloudWatch is a service that can mitigate DDoS attacks.
- AWS Shield is another service for mitigating DDoS attacks
Storage Service for Data Appendage
- S3 is the recommended storage service for appending data simultaneously by hundreds of EC2 instances
Route 53 Routing Policy
- Weighted Routing Policy is used to route traffic to multiple resources and determine the traffic distribution to each resource.
Serverless AWS Service
- Lambda is a serverless AWS service
Advantages of AWS Cloud
- AWS Cloud offers trade-off of capital expense for variable expense.
- Reduced infrastructure capacity guesswork
- Quicker deployment and faster time to market,
AWS Region Replication
- Cross-Region Replication (CRR) copies data between different regions most efficiently.
AWS Managed Services
- AWS RDS managed service offers better performance than a customer-managed database.
- The customer avoids patching the underlying OS.
- The customer isn't required to manage backups.
VPC Endpoint Gateway
- Amazon S3 and Amazon EC2 support VPC Endpoint Gateway for a private connection
Cost-Effective S3 Storage
- The most cost-effective storage class for less frequently accessed data is S3 Intelligent-Tiering.
Security Service, No Additional Costs
- AWS Shield Standard is enabled for all AWS customers by default at no extra charge
Cloud Agility
- AWS cloud architecture allows for quick iterations by quickly leveraging AWS services to deploy new features.
Scaling Principle
- Fault tolerance is achieved with horizontal scaling, where resources are duplicated and increased, not by increasing power of the original machine.
Cloud Computing Advantages
- Economies of scale, by reducing capital expenditure costs.
- Faster global deployments using multiple regions.
- Flexible deployments with quick start-up options.
Database Replication in a Single Availability Zone
- Configuring the RDS database in Multi-AZ mode with automatic failover allows to continue database operations in case of AZ failures.
AWS Expense Areas in Cloud Migration
- Eliminating hardware expenses and application license fees results in saving operational expenses

- Amazon Redshift is an AWS database service.
- Amazon EBS is an AWS storage service
Cloud Computing Type for EC2
- EC2 represents Infrastructure as a Service (IaaS).
Availability Zone Storage Characteristics
- EBS volumes can be attached to one or more instances within the same Availability Zone and EFS file systems can be mounted across multiple Availability Zones
Time Most to Retrieve Data
- S3 Glacier Deep Archive storage class takes the most time to retrieve data (first byte latency).
Storage Cost-Effective Solution for Computation Application
- EBS is a cost-effective solution for high-performance and fault tolerant applications.

- Security of the AWS global infrastructure is AWS's responsibility while security for the operating system inside Amazon EC2 instances falls on the customer.
Computing Model for Data and Applications Management
- The best model for managing data and applications is Platform as a Service (PaaS).
Deployment Model
- When on-premesis data centers are combined with AWS cloud, this is a hybrid deployment architecture
Flexible Schema Database Service
- Amazon DynamoDB supports flexible schemas and document data models
Container Applications
- Amazon Elastic Container Service - Fargate is the service to run container applications without handling server management.
Accessing File-Based Data
- EFS is the recommended service to access file-based data.

- On-Demand Instances are the most flexible and cost-effective option for AWS instances,
Firewalls
- Security Groups are firewalls acting at the instance level, and Network Access Control Lists (NACLs) are firewalls operating at the subnet level
AWS Storage Services
- S3, EBS, & EFS are object-based, block-based, and file-based storage respectively.
Multi-AZ RDS Benefit
- Multi-AZ configuration for RDS databases enhances database availability and resilience to regional failures.
Global Infrastructure Deployment
- A Global infrastructure is a deployment comprising multiple data centers with redundant connectivity, power, and networking.
Cloud Computing Model Focus
- A PaaS (Platform as a Service) model is appropriate if only managing applications and data is desired. This is where the customer only manages the applications and data. It eliminates the need to manage the compute resources.
Cloud Pricing
- The most common pricing model for cloud computing is Pay-as-you-go.
