Key Products: Three-Tier Design Flashcards
AWS Regions and Availability Zones
Amazon EC2 is hosted on multiple locations world-wide. These locations are composed of regions and Availability Zones. Each region is seprate geographic area. Amazon EC2 provides you with the ability to place resources, such as instances and data, in multiple locaitons.
Availability Zones
Within a region are two or more availability zones. The availability zone is isolated, but the availability zones in a region are connected through low-latency links.
Edge Locations
Edge location = AWS lambda edge, amazon cloudfront, amazon route 53, AWS shield, and AWS WAF services that are offered at AWS edge locations
Hybrid cloud architecture
Integration of on-premises resources with cloud resources.
Amazon Route 53
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service.
Amazon Cloudfront
Amazon Cloudfront is a web service that speeds up distribution of your static and dynamic web content to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations.
Amazon VPC
A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. It is logically isolated from other virtual networks in the AWS cloud. You can launce your AWS resources, such as Amazon EC2 instances, into your VPC.
Internet Gateways
An Internet gateway is a horizontally-scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet.
Subnets
A subnetwork or subnet is a logical subdivision of an IP network.
Route Tables
A route table is a set of rules that is used to determine where data packets traveling over an Internet Protocol (IP) network will be directed.
Amazon EC2 Security Groups
A security group acts as a virtual firewall that controls the traffic for one or more instance.
AWS Elastic Load Balancing
Elastic Load Balancing automatically distributes your incoming application traffic across multiple targets, such as Amazon EC2 instances. It monitors health of registered targets and routes traffic only to healthy targets. Elastic Load Balancing supports two type of load balancers: Application Load Balancer and Classic Load Balancer.
Amazon Elastic Compute Cloud (Amazon EC2)
Amazon Elastic Computer Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud.
Auto Scaling
Auto Scaling helps you maintain application availability and allows you to scale your Amazon EC2 capacity up or down automatically according to conditions you define.
Amazon Relational Database Services (Amazon RDS)
Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the cloud.
