Amazon

- IaaS (Infrastructure-as-a-Service) - PaaS (Platform-as-a-Service) - SaaS (Software-as-a-Service)

1. Regions 2. Availability Zones 3. Edge Locations

Created in IAM. Set permissions for multiple users. Contain user policies.

JSON key value pairs that provide rules to what a user or group can do in AWS.

Simple Storage Service

Fully redundant data storage for object-based storage. (Images, files, static web pages, etc.)

A location to store objects in S3. Similar to a directory in computer. Each bucket has a globally unique name, and can be accessed globally.

Similar to S3, but for long term storage. Cheaper, but requires larger files and takes 3-5 hours to retrieve files.

1. Bucket Policies - Apply to a bucket. 2. Access Control Lists - Apply to individual objects.

Uses edge locations to upload files.

Content-Delivery Network (CDN) service from AWS. Uses edge locations to cache files.

The origin of all files that the CDN will distribute. Can be S3, EC2, ELB, or Route 53.

1. Web distribution - Collection of Edge locations used for Cloudfront websites. 2. RTMP - Specific Cloudfront edge locations used for streaming.

Eventually correct. Older versions can be invalidated immediately, for a fee.

Elastic Compute Cloud

Virtual Servers on the cloud.

1. On Demand 2. Spot 3. Reserved 4. Dedicated

Charged as needed. Most expensive but most agile.

Bought by bid and only temporary. Cheapest but very few use cases.

Paid all or partly ahead of time for 1 or 3 years. Cheapest besides spot. Most reliable.

Own specific serves in cloud. Expensive and obly used for corner cases.

Elastic Block Storage. Disk in the cloud. Block based.

1. General Purpose SSD 2. Provisioned IOPS SSD 3. Throughput Optimized HDD 4. Cold Hard Disk HDD

Roles are easier to manage and track then access keys.

Relational Database Service

1. Multi AZ for disaster recovery 2. Read Replicas for performance

Predictable and Scalable NoSQL Data Store

1. Public 2. Hybrid 3. Private

Elastic Map Reduce (Big data service, can use Hadoop etc.)

Amazon's proprietary big data service. Used for business intelligence and data warehousing.

VPC Elastic Beanstalk CloudFormation IAM Auto Scaling Opsworks Consolidated Billing (Anything these target or provision is not free)

Key Value pairs attached to resources Data about data

Group resources by tags

Allows all billing in one place for ease of use Allows multiple accounts to share reserved instance pricing, etc.

Creates a combination of AWS resources for the user to quickly start operations.

1. Simply Monthly Calculator (Estimated cost of specific products by month.) 2. Total Cost of Ownership (TCO) Calculator - Compares current private cloud costs to projected costs of switching to AWS public cloud.

Aws manages security OF the cloud. User manages security IN the cloud.

Web Application Firewall

A special type of firewall that looks more deeply into packets that carry HTTP traffic.

Managed DDOS protection service. Standard (Free) vs Advanced.

Product installed on EC2 to evaluate security.

Looks at a range of metrics on a range of AWS products for security, pricing, best practice, etc.
