Elastic Load Balancing
highly available service that distributes traffic across Amazon EC2 instances and includes options that provide flexibility and control to incoming requests to Amazon EC2 instances
internet-facing load balancer
type of load balancer that takes requests from clients over the internet and distributes them to Amazon EC2 instances that are registered with a load balancer
listener
process that checks for connection requests, configured for the elastic load balancer
Auto Scaling
service that allows you to scale your amazon EC2 capacity automatically by scaling out and scaling in according to criteria that you define

Maintain Current Instance Levels
Manual Scaling
Scheduled Scaling
dynamic scaling
launch configuration
template that Auto Scaling uses to create new instances
what five things is the launch configuration composed of
Configuration Name
Amazon Machine Image
Amazon EC2 instance type
Security Group
instance key pair
Scaling policy
used by auto scaling with cloud watch alarms to determine when your auto scaling group should scale in or out
VPC
a logically isolated network in the AWS CLoud
what five Core elements do a VPC include
subnet
route tables
DHCP option sets
security groups
network ACLs
public subnet
a subent whose traffic is routed to an IGW
private subnet
a subent with no route to an IGW
VPN-only subnet
a subent with no route to an IGW, but has its traffic routed to a VPG
IGW
horizontally scaled, redundant and highly available Amazon VPC component that allows communication between instances in your Amazon VPC and the internet
public IP address
an AWS-owned IP that can be automatically assigned to instances launched within a subnet
Elastic IP address
an AWS-owned IP that you can allocate to your account and assign to instances or network interfaces on demand
Amazon VPC Endpoint
enables you to create a private connection between your Amazon VPC and another AWS service without requiring access over the internet or through a NAT instance. Support is within a region only
Amazon VPC peering
a networking connection between two VPCs that enable instances in either Amazon VPC to communicate with each other as if they are within the same network. Created through request/accept protocol.
CGW
represents a physical device or a software application on the customer's side of the VPN connection

Magnetic Volumes
provide an average performance of 100 IOPS and can be provisioned up to 1 TB. Good for cold infrequently accessed data
General purpose SSD
provide three IOPS/GB up to 10,000 IOPS, with smaller volumes able to burst 3000 IOPS. They can be provisioned up to 16 TB are are appropriate for dev/test environments, small databases, and so forth.
Provisioned IOPS SSD
can provide up to 20,000 consistent IOPS for volumes up to 16 TB. they are the best choice for workloads such as large databases executing many transactions
Amazon s3 cloud object storage
manages data at the application level as objects using a REST API built on HTTP
Block storage
manages data at the operating system level as numbered addressable blocks using protocols such as SCSI or fibre channels
File storage
manages data as shared files at the OS level usnig protocols such CIFS or NFS
Bucket
simple flat folder that stores objects
lifecycle configuration
these rules define actions to transition objects from one storage class to another based on time
event notification
set at the bucket level and can trigger a message in Amazon SNS or AMazon SQS or an action in AWS LAmbda in response to an upload or a delete of an object
