Using The Cloud Flashcards
What is Network Functions Virtualization (NFV)?
Decoupling of network functions from hardware devices
What does NFV allow for in cloud computing?
Flexible deployment and management of networking services
What does NFV reduce the need of?
Dedicated hardware
What does NFV enhance?
Resource utilization and reduces costs
What is a virtual private cloud (VPC)?
An isolated network space within a public cloud
How are VPCs designed?
Provides a similar level of segmentation, control, and security as a private data center
What can users do in their own VPCs hosted within a public cloud?
Define their IP address range, configure subnets, route tables, and network gateways
What do VPCs allow enterprises to do as if they would manage a network in their own data center?
Run their cloud resources in a virtual network
What are network security groups used for?
To control inbound and outbound traffic to cloud resources within a VPC
How are network security lists used?
Manage and secure network traffic in a cloud environment
What do network security groups and lists provide?
Stateful or stateless traffic filtering on a subnet level within the same or different VPNs
What do network security groups and lists act as?
A virtual firewall
What does the internet gateway enable?
Internet access for the resources within the VPC
What does a NAT gateway allow?
Allows instances in a private subnet to connect to the internet while preventing an external system connecting directly toward them
Why are NAT gateways crucial for instances that require outbound internet access?
For updates
What cab cloud gateways server as?
An intermediary device or service that connects cloud environments with different networks
What can cloud gateways facilitate between dissimilar environments?
Users and applications can securely and efficiently access cloud resources
What does cloud collectively options refer to?
Methods through which data and applications can connect to and interact with cloud environments
How are these cloud connectivity options crucial when accessing the cloud?
Offer efficient, reliable, and secure access to cloud resources from different locations
What is the private-direct connection to the cloud provider?
Dedicated network link between an organization’s on-premises infrastructure and a cloud service provider’s data center
What does the private-direct connection offer when bypassing the public internet?
Reliability with secure and faster connectivity for accessing the cloud services
Where would private-direct connections be ideal?
For business with strict performance and security requirements for their cloud-based applications and data
What do deployment models in networking and cloud computing refer to?
Specific configurations in which technology services and infrastructure are implemented
What does the deployment of public cloud offer?
Multi-tenant third-party services that anyone can use
What do organizations share within a public cloud?
Hardware resources are shared with other different organizations
What are the two features of public cloud?
Most affordable and least secure
What private cloud options differ from a public cloud?
Single tenant service where no hardware resources are shared among organizations
Which cloud deployment model is most expensive and secure?
Private cloud
Who can host a private cloud?
The company that owns it with its own hardware and data centers or cloud providers
What do organizations in a community cloud share?
Interests such as mission, policy, and compliance considerations
Who manages the community clouds?
The organization itself or a third-party
What is a hybrid cloud?
A combination of any cloud services also being host on-premises
How are these hybrid clouds bounded together?
Standardized or proprietary technologies
What do hybrid clouds enable?
Data and application portability
