AWS Cloud Practitioner Study Notes
Region = Geographical area. Each consists of two (or more) availability zones. Availability zone = Data Center.
Edge locations are CDN endpoint for CloudFront. There are many more edge locations
than regions.
Networking & Content Delivery: VPC (Virtual Private Cloud); Route53 (DNS); Cloud Front; Direct connect. Compute: EC2 (VMs in the cloud); EC2 Container Service; Elastic Beanstalk; Lambda (serverless); Lightsail. Storage: S3 (simple storage server, virtual disk in the cloud where you can store objects ); Glacier (data archival); EFS (Elastic File Services, file based storage where you can install apps and share with multiple EC2s); Storage gateway. Databases: RDS (Relation Database Services); DynamoDB (non-relation DB); Redshift (big data); Elasticache (cache data in cloud). Security & Identity: IAM (Identity Access Management); Inspector (agent installed on VMs); Certificate Manager; Directory services (use AD in AWS); WAF (Web Application Firewall); Artifacts (compliance docs). Management tools: Cloud Watch (performance monitor); Cloud Formation; Cloud Trail (auditing aws resources); Opsworks; Config (audit and set alerts); Service Catalog; Trusted Advisor. Desktop & App Streaming: WorkSpaces (VDI); AppStream 2. Messaging: SNS (Simple Notification Service); SQS (Simple Queue Service); SES (Simple Email Service). Migration: Snowball (transfer content of local disks to virtual disks); DMS (DB migration services, can be done from production, no downtime); SMS (Server Migration Services, replicate local VMs to the cloud); Application Services: Step Functions (what is going on inside micro apps); SWF (Simple Workflow Services); API Gateway;
AppStream; Elastic Transcoder (change video format to fit a variety of devices). Artificial Intelligence: Alexa; Polly (turn text to voice); Machine Learning; Rekognition (tell what is in the picture). Developer Tools: CodeCommit (place to store a code); CodeBuild (way to compile a code); CodeDeploy (deploy code in EC2 instances); CodePipeline (way of keep tracking of different codes). Mobile Services: Mobile Hub; Cognito; Device Farm; Mobile Analytics; Pinpoint. Business Productivity: WorkDocs; WorkMail. Analytics: Athena; EMR (big data); Cloud Search; Elastic Search; Kinesis; Data Pipeline; Quick Sight.
Scalability involves beginning with only the resources you need and designing your architecture to automatically respond to changing demand by scaling out or in. As a result, you pay for only the resources you use. The AWS service that provides this functionality for Amazon EC2 instances is Amazon EC2 Auto Scaling.
Dynamic scaling responds to changing demand. Predictive scaling automatically schedules the right number of Amazon EC instances based on predicted demand.
Elastic Load Balancing: is the AWS service that automatically distributes incoming application traffic across multiple resources, such as Amazon EC2 instances. A load balancer acts as a single point of contact for all incoming web traffic to your Auto Scaling group. Although Elastic Load Balancing and Amazon EC2 Auto Scaling are separate services, they work together to help ensure that applications running in Amazon EC2 can provide high performance and availability.
Low-demand period and high-demand period
