APIs
Application Programming Interface communication between clients and servers or
applications and servers
4 different kinds:
SOAP APIs
RPC APIs
WebSocket APIs
REST APIs
AWS Cost Explorer
easy-to-use interface that lets you visualize, understand, and manage your AWS costs
and usage over time.
Analyze your data at a high level (for example, total costs and usage across all
accounts) or dive deeper into your cost and usage data to identify trends, pinpoint cost
drivers, and detect anomalies.
AWS Cost and Usage Report
contains the most comprehensive set of AWS cost and usage data available, including
additional metadata about AWS services, pricing, and reservations
AWS Command Line Interface (CLI)
A unified tool to manage your AWS services, can control multiple AWS services from
the command line and automate them through scripts
Elastic Load Balancer
automatically distributes incoming application traffic across multiple targets and virtual
appliances in one or more Availability Zones (AZs).
Three types:
,Application load balancing
Gateway Load Balancing
Network Load Balancing
Amazon EC2 Instance Types
1. General Purpose instances 2. Compute Optimized Instances 3. Memory Optimized
Instances 4. Accelerated Computing Instances 5. Storage Optimized Instances
General Purpose instances
provide a balance of compute, memory, and networking resources
Compute optimized instances
ideal for compute-bound applications that benefit from high-performance processors
Memory optimized instances
designed to deliver fast performance for workloads that process large datasets in
memory
Accelerated computing instances
use hardware accelerators, or coprocessors, to perform some functions more efficiently
than is possible in software running on CPUs. Examples of these functions include
floating-point number calculations, graphics processing, and data pattern matching.
Storage Optimized Instances
designed for workloads that require high, sequential read and write access to large
datasets on local storage. Examples of workloads suitable for storage optimized
instances include distributed file systems, data warehousing applications, and high-
frequency online transaction processing (OLTP) systems.
Amazon EC2 instance pricing types
1. On-demand pricing 2. Reserved-Instance pricing 3. Spot Pricing 4. Savings Plan
Pricing
On-demand pricing
No long-term commitment instance pricing model that does not allow for interruptions.
Reserved Instances
Provide you with a capacity reservation, and offers discount on the hourly charge for an
instance (up to 75% off ondemand). 1 Year or 3 Year terms
Spot Instances pricing
, name your own price for EC2 computing capacity. Bid on spare EC2 instances -auto-
whenever your bid exceeds the current spot price. If your bid goes below the spot price
after these instances are provisioned, your instances will automatically be terminated.
90% discount
terminated instance= not charged
Savings Plan Instances
Long term commitment of usage for up to 72% off on demand pricing.
AWS Global Infrastructure
Regions, Availability Zones, Edge Locations
AWS Regions
Physical location around the world where AWS clusters data centers. AWS Region
consists of multiple, isolated, and physically separate AZ's within a geographic area
AWS Availability Zone
A collection of one or more data centers. Three or more AZs make up a Region.
AWS Edge Locations
An AWS Edge location is a site that CloudFront uses to cache copies of the content for
faster delivery to users at any location.
Also used by AWS Global Accelerator
Infrastructure as Code
Managing a hardware and software infrastructure using the same principles as
developing computer code.
Cloud Formation uses IaC
Amazon Machine Image (AMI)
supported and maintained image provided by AWS that provides information required to
launch an instance
An AMI is used in one of the following:
EBS snapshots
Templates for root volume of instance (ex. operating systems, applications)
Launch permissions that control which AWS accounts can use the AMI to launch
instances
