Study Notes
AWS OutPost Zones
- On-premise infrastructure integrated into AWS Cloud, managed as Cloud resources with AWS API and tools.
Amazon CloudFront
- Cloud-based content distribution network (CDN) that delivers content from a location close to the requestor.
- To use Amazon CloudFront, store original versions of files in an Amazon S3 bucket, create a distribution, and use the distribution's domain name in web pages or applications.
- Pay only for data transfer and requests used, with protection from DDoS attacks by AWS Shield.
AWS Edge Location
- Used only for AWS managed services (CDN, firewall, DDoS protection, routing to AWS backbone network).
- Edge locations keep cached copies of content closest to end users, with Point of Presence (POP) serving content directly to viewers.
- Regional Edge Caches, with 600+ edge locations and 13 regional edge caches.
Amazon Elastic Compute Cloud (EC2)
- Provides virtual machines running inside the Amazon Cloud, with instance storage tied to the hosting server.
- Offers network-accessible block storage that persists across time and can be mounted in the VM.
- Allows creation of AMI with a single command, requiring installation and use of AMI tools.
Instance States
- Pending: instance is preparing to enter the running state, not billed.
- Running: instance is running and ready for use, billed.
- Stopping: instance is preparing to be stopped or hibernated, not billed if preparing to stop, billed if preparing to hibernate.
- Stopped: instance is shut down and cannot be used, not billed.
- Shutting-down: instance is preparing to be terminated, not billed.
- Terminated: instance has been permanently deleted and cannot be restarted, not billed.
Instance Placement Groups
- Cluster placement group: logical grouping of instances to increase network performance.
- Partition placement group: spreads instances across partitions to reduce correlated hardware failures and improve performance.
- Spread placement group: spreads instances across distinct underlying hardware to reduce correlated hardware failures.
Pricing
- On-demand pricing: https://aws.amazon.com/ec2/pricing/on-demand/
- Reserved instances pricing: https://aws.amazon.com/ec2/pricing/reserved-instances/pricing/
- Spot-Market pricing: https://aws.amazon.com/ec2/spot/pricing/
- Data transfer pricing: varies based on location and type of transfer.
- Block storage and Elastic IP addresses pricing: varies based on type of storage and usage.
Amazon EC2
- Infrastructure as a service, with flexible instance types and large variety of Amazon Machine Instances.
- Pricing options include On-Demand, reserved, and spot market pricing.
Base Technologies for Accessing the Cloud
- Mobile processors: Wi, DSL, ARM, and Apple M3.
- ARM BIG Little and Apple M3 SoC specifications.
- WLAN: Wireless Local Area Network, IEEE 802.11 standards, and Wi-Fi.
