Study Notes
AWS - Amazon Web Services
- Amazon started as an online bookstore, and AWS was launched on March 13, 2006; it's now one of the top cloud providers
- Estimated to have over 2 million servers
- AWS pioneered the IaaS (Infrastructure as a Service) model, offering compute, network, and storage services
AWS Services
- Compute: Running VMs based on Amazon Machine Images (AMIs)
- Storage: Amazon Simple Storage Service (S3) for reliable and inexpensive data storage
- Network: Availability Zones, Regions, and Elastic IP addresses for flexible network configurations
AWS - Resource Distribution
- Geographic cluster of Availability Zones (AZs) with 33 regions and 105 AZs
- User can control resource allocation for fault tolerance, latency, and legal requirements
- Regions are isolated for fault tolerance and stability, with communication among regions incurring costs
AWS - Availability Zones
- Availability Zone: equivalent to a data center
- 33 regions and 105 Availability Zones, with two AZs having no common points of failure for infrastructural redundancy
- User can control the zone for VM startup, and communication within a zone is free, while between zones it has to be paid
Amazon Simple Storage Service (S3)
- Reliable and inexpensive data storage infrastructure
- Supports objects from 1 byte to 5 TB, with two-level namespace (buckets and objects)
- Slow compared to local discs or EBS, with high durability but low availability
- Most users use S3 for short-term or long-term backup
Amazon EC2 Instance
- Running VM based on an Amazon Machine Image (AMI), with instance type determining compute and memory capabilities
- Boot device volume: Elastic Block Storage (EBS) and Instance Storage, with persistency achieved using EFS or EBS
- List of instance types, including M7 with AWS Graviton, Intel, and AMD CPUs
- Elastic IP address: static IP address for always-accessible instances, with account limits on VMs of a certain type
AWS EC2 Instance Lifecycle
- Boot time, root device volume, data persistence, and charges vary between EBS-backed and Instance Store-backed instances
- Instance lifecycle: reboot, stop/start, hibernate, and terminate, with differences in host computer, IP addresses, and charges
Base Technologies for Accessing the Cloud
- Mobile processors: ARM, a British company acquired by SoftBank, developing processor designs for mobile devices
- ARM Big Little, and Apple M3, a System-on-Chip (SoC) fabricated by TSMC 3 nm process, with varying performance, efficiency, and GPU cores
- WLAN: Wireless Local Area Network, using IEEE 802.11 standards, marketed as Wi-Fi, consisting of clients and access points acting as routers
