GCP Structure and Network Flashcards
The purpose of this deck is to provide an overview of the layout for resources and the various areas of networking
1
Q
GCP Resource Types
A
Global
|_ Multi-Region
|_ Region
|_ Zone
2
Q
What is a is an independent geographic area that consists of Zones referred to as?
A
Region
3
Q
Regions
A
- Consist of Zones
- Tend to have round-trip network latency under 5 milliseconds on the 95th percentile
4
Q
What is a deployment area for Google Cloud Platform resources within a region
A
A Zone
5
Q
What is a Zone?
A
- A zone is a deployment area for Google Cloud Platform resources within a region
- A zone as a single failure domain within a region
6
Q
Describe Zonal Resources
A
- Zonal resources operate within a single zone
- If a zone becomes unavailable, all of the zonal resources in that zone are unavailable until service is restored.
7
Q
Describe Regional Resources
A
8
Q
Describe Multi-regional Resources
A
- Some Google Cloud Platform services are redundant and distributed within and across regions.
- Multi-regional resources require a reduction in either latency or consistency
- Multi-regional services:
- Google App Engine and its features
- Google Cloud Datastore
- Google Cloud Storage
- Google BigQuery
9
Q
What are PoPs?
A
- These are Googles points of presence
- This is where Google’s network is connected to the rest of the internet
10
Q
What is a Virtual Private Cloud (VPC)
A
- A VPC is a Global resource
- VPC is a comprehensive set of Google-managed networking objects
- VPC provides IP addresses for internal and external use, along with granular IP address range selections
- Provides networking functionality to Compute Engine, Google Kubernetes Engine (GKE), and App Engine - as well as for any other Google Cloud resources built on Compute Engine
- Provides various network related services (load balancing/VPN/firewall)
11
Q
GCP Projects
A
A Project in GCP is a collection of resources
12
Q
Describe Subnets in GCP
A
- Subnetworks allow you to divide or segregate your environment
- Subnetworks cross all zones in a region
- A subnet is simply an IP Address range
13
Q
What are the 5 means of connecting on premise networks with your GCP instance?
A
Layer 3
- Direct Peering
- Carrier Peering
- VPN
Layer 2
- Direct interconnect
- Partner interconnect
