Scaling of resources based on demand
Elasticity
Multitenancy
Many different clients using the same cloud infrastructure
Replacement of physical network components with virtual ones
Network Functions Virtualization (NFV)
T F: Virtual devices have the same functionality as physical devices
T. Virtual devices are capable of being configured in the exact same way as physical
Benefit of deploying network functions virtually
Quick and easy deployment and management
Pool of resources created in a public cloud
Virtual Private Cloud (VPCs)
Why is it common to create many different VPCs for different applications?
Separate VPCs improve organization and security
What does a transit gateway do?
Connects multiple VPCs to VPCs and users to VPCs
What is the function of a site-to-site VPN in cloud architecture?
Allows users to connect to transit gateways
How are VPCs made more secure?
They are placed on separate subnets
Allows for internet users to connect to a VPC
Internet gateway
What does a VPC NAT gateway allow for?
Private cloud subnets can connect to external resources
Direct connection between cloud provider networks
VPC Endpoint
Effectively firewalls for the cloud
Network security groups / Network security lists
Assigns security rules to entire IP subnets
Network Security List
Characteristics of Network Security Lists
Very broad and low granularity
Assigns security rules to specific VNIC s (Virtual Network Interface Cards)
Network Security Group
Characteristics of Network Security Groups
Better control and higher granularity
Cloud model available to everyone over the internet
Public model
Cloud model located on own virtualized local data center
Private model
A mix of private and public cloud models
Hybrid model
What is Software as a Service (SaaS)?
On-demand software developed and managed by someone else
What is Infrastructure as a Service (IaaS)?
Outsourcing of physical equipment instead of software
What is Platform as a Service (PaaS)?
Someone else handles the platform, you handle the developement
