Google Cloud Network Endpoint Groups – NEG
- Network Endpoint Groups (NEG) is a configuration object that specifies a group of backend endpoints or services.
- Network Endpoint Groups provides a logical grouping of IP addresses and ports for software services instead of entire VMs.
- NEGs can be used as backends for External and Internal HTTP(S) load balancers, TCP/SSL Proxy load balancers, and with Traffic Director
- Zonal NEG
- contains one or more endpoints that can be Compute Engine VMs or services running on the VMs.
- are zonal resources that represent collections of either IP addresses or IP address/port combinations for Google Cloud resources within a single subnet.
- Each endpoint is specified either by an
IP address or an
- All other backends in that backend service must also be zonal NEGs.
- Zonal NEG can be used as a backend for more than one backend service
- Backend services using zonal NEGs for backends only support balancing modes of RATE or CONNECTION. UTILIZATION is not supported
- Internet NEG
- contains a single endpoint that is hosted outside of Google Cloud. This endpoint is specified by hostname
- can use an internet NEG as the backend for a backend service for a Google Cloud external HTTP(S) load balancer.
- does not support other load balancer types.
- ideal to serve content from an origin hosted outside of Google Cloud, and needs to be fronted by external HTTP(S) load balancer
- allows you to
- Use Google Edge infrastructure for terminating the user connection
- Direct the connections to your custom origin.
- Use Cloud CDN for your custom origin.
- Deliver traffic to the public endpoint across Google’s private backbone, which improves reliability and can decrease latency between client and server.
- Serverless NEG
- points to Cloud Run, App Engine, Cloud Functions services residing in the same region as the NEG.
- Zonal and internet NEGs define how endpoints should be reached, whether they are reachable, and where they are located.
- Serverless NEGs don’t contain endpoints.
- A hybrid connectivity NEG points to Traffic Director services running outside Google Cloud.
GCP Certification Exam Practice Questions
- Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
- GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
- GCP exam questions are not updated to keep up the pace with GCP updates, so even if the underlying feature has changed the question might not be updated
- Open to further feedback, discussion and correction.
