2.2 Summarize virtualization and cloud computing concepts Flashcards
Virtual Machine
running multiple OS on a single computer.
Hypervisor
Software that allows you to run a VM. (also known as virtual machine monitor (VMM))
Types of Hypervisor
Type 1: Software that runs directly on the hardware.
Type 2: The OS that runs the hypervisor is installed on top the hardware.
VM Sprawl
Organization has too many VM that have no process to manage it . Administrators can not mange them.
VM Escape (attack)
Attacker is able to jump from one virtual machine to the next.
Infastructures as code
Code that describes the application description and then is deployed. Allow application instances follow a specific config setting.
SDN
(Software Defined Networking) is a network that separates the control plane and data plane.
SDV
(Software defined Visibility) Allows virtual firewalls to be placed instead of placing them physically. Focus on encryption
Edge computing
IoT that specific and don’t need to be on the internet to function. Ran of your local network.
Fog Computing
Separates local data and cloud data. Devices that send specific data to the cloud but doesn’t need to send everything to the cloud.
IaaS
(infrastructure as a Service) Only provides the hardware for the infrastructure
SaaS
(Software as a Service)
On demand software Third party takes care of the application.
PaaS
(Platform as a Service)
middle ground of IaaS and SaaS. Provides you with infrastructure but no on software or management. Allows you to build your app.
XaaS
(Anything as a service) Any service provided over the cloud.
On/Off Premises
All infrastructure located in house/locally. Off is the opposite of on On Premises
CPS
Cloud service Provider
Third parties that sell cloud services.
MSP
Managed Service Providers. They manage and repair the service.
MSSP
Manage Security Service Provider
They focus on security for CPS.
Cloud Deployment Models
Public
Community
Private
Hybrid
Public Cloud
Service that everyone has access too.
Community Cloud
Organizations that come to together to share a cloud service. Cost efficiency
Private Cloud
Virtualized your own data center locally
Hybrid Cloud
A mixture of pubic data and Private cloud data
Thin Client
a device that allows you to connect to a virtual desktop. Also called a VDI (virtual Desktop Infrastructure)
Containerization
Seperates apps data within VM
Microservice
Architecture
Uses API to break up different Services
Serverless Architecture
Application are up into a computerized container and built and disabled as needed.
Transit Gateway
VPC (virtual Private Cloud) is a router within the cloud. that takes you to different VPC
Resource Policies
Restricts services being built within the cloud.
Service Integration
Mixing different CPS you need to use SIAM (Service Integration and Management) allows to view all different clouds at once.
