Introduction 📝 

In this article, we will discuss what Network Service Tiers are in google cloud and the types of Network Service Tiers. We will also discuss the regions supporting the standard tier and more about Network Service Tiers.

Network Service Tiers

Google Cloud is the first large public cloud to offer a tiered network with Network Service Tiers. Choose the best network service tier for your needs and budget. Let's Understand the Network Service Tiers in detail:

Network Service Tiers overview 🌐

Network Service Tiers allow you to improve the connection between internet-connected equipment and Google Cloud instances. Premium Tier traffic is routed over Google's premium backbone, whilst Standard Tier traffic is routed through standard ISP networks.

Premium Tier should be used to optimize for performance, while Standard Tier should be used to optimize for cost. Let's compare both the tier:

Premium Tier

Standard Tier

Highest performance: Traffic between the internet and VM instances in your VPC network is routed as much as feasible within Google's network.

Cost-effective: Traffic between the internet and VM instances in your VPC network is often routed through the internet.

 

For services that require worldwide accessibility.

 

For services hosted entirely within a region.

Unless you make configuration changes. Premium Tier is the default.

Performance is comparable to those of other cloud service providers.

 

 

Each Network Service Tier has its own egress cost. See Network Service Tiers Pricing for further details.

 

use cases for the Standard Tier and Premium Tier

The suggested use cases for the Standard Tier and Premium Tier are shown in this figure.

🔖Network Service Tiers and Google Cloud resources

Google Cloud has two sorts of external IP addresses: global and regional.

External IP address type Premium Tier Standard Tier

Global external IPv4 and IPv6 addresses

 

Anycast IP addresses that are publicly routable.

✅Supported

❌ Not supported

Regional external IPv4 addresses

 

IPv4 addresses that are publicly routable and assigned to a single Google Cloud area for usage by resources.

✅Supported

When IP addresses are utilized with approved resources, support is provided.

IP addresses imported to Google Cloud utilizing bring your own IP are not supported (BYOIP).

 

Regional external IPv6 addresses

 

IPv6 addresses that are publicly routable and assigned to a single Google Cloud region for usage by resources.

✅Supported

❌ Not supported

The network is built to maintain traffic between virtual machine (VM) instances in the same area on Google's network, regardless of the tier you use, even if a load balancer is in the way. This is true irrespective of whether the transmission utilizes openly or secretly routable IP addresses.

🔖Regions supporting Standard Tier

Only resources that use local external IP addresses in the following Google Cloud regions are eligible for Standard Tier. The external HTTP(S) load balancer must utilize a regional external IP address and choose Standard Tier if Cloud Storage buckets are being used as the backends for HTTP(S) Load Balancing.

  • asia-east1
  • asia-east2
  • asia-northeast1
  • asia-northeast3
  • asia-south1
  • asia-southeast1
  • asia-southeast2
  • australia-southeast1
  • europe-north1
  • europe-west1
  • europe-west2
  • europe-west3
  • europe-west4
  • Europe-west6
  • Northamerica-northeast1
  • southamerica-east1
  • us-west1
  • us-west2
  • us-west3
  • us-west4
  • us-central1
  • us-east1
  • Us-east4

🔖Traffic routing

The routing variations for each of the Network Service Tiers are listed in this table.

Traffic

Premium Tier

Standard Tier

Ingress to Google Cloud

Google's network receives traffic from your users at a node that is close to them.

In the location where you have installed your Google Cloud services, traffic from your users enters Google's network through peering, ISP, or transit networks.

Egress from Google Cloud

cold potato routing

Egress traffic is routed over Google's backbone network and exits at the global edge point of presence (PoP) that is most convenient for your consumers.

hot potato routing

A peering or transit network located in the Google Cloud area from whence it originates is used to send egress traffic to the internet.

🔖Premium Tier

The Premium Tier routes traffic from external systems to Google Cloud services across Google's low-latency, high-reliability worldwide network. This network is made up of a large private fiber network with over 100 points of presence (PoPs) throughout the world. This network is intended to withstand several failures and disturbances while continuing to distribute traffic.

For VM instances and load balancers, Premium Tier supports both regional and global external IP addresses. Premium Tier must be used for all global external IP addresses. 
 

Premium Tier

Routing path for Premium Tier

 

Incoming traffic from internet-connected systems enters Google's high-performance network at the PoP nearest to the sending system with Premium Tier. Traffic is directed from that PoP within Google's network to the VM in your Virtual Private Cloud (VPC) network or the nearest Cloud Storage bucket. Outbound traffic is routed through Google's network and terminates at the nearest PoP to its destination. By decreasing the number of hops between end users and the PoPs nearest to them, this routing strategy reduces congestion and maximizes performance.

🔖Standard Tier

The Standard Tier routes traffic from external systems to Google Cloud services over the internet. It only uses Google's network's double redundancy up to the point when Google's data center links to a peering PoP. Packets leaving Google's network are delivered over the public internet, which is subject to the dependability of intermediary transit providers and ISPs. Standard Tier network quality and dependability are comparable to other cloud providers. Premium Tier or Standard Tier can be used for regional external IP addresses.
 

Standard Tier

The routing path for Standard Tier

 

Standard Tier is less expensive than Premium Tier because traffic from internet-connected devices is routed through transit (ISP) networks before reaching VMs in your VPC network or regional Cloud Storage buckets. Regardless of the destination, standard Tier outbound traffic generally leaves Google's network from the same location as the sending VM or Cloud Storage bucket. In exceptional instances, such as during a networking event, traffic may be unable to escape through the nearest exit and may be routed through another exit, maybe in another area.

Set the network tier ⚙️

This section explains how to configure a network tier for your workloads. Before manually configuring a network tier, study the Network Service Tiers overview

🔖Specifications

Network Service Tiers are only supported by Google Cloud resources that are qualified. Standard Tier is only offered in certain areas. Every Google Cloud area offers Premium Tier.

📍External IP address pools

The pool from which an external IP address is picked is determined by whether it is regional or global (and, if regional, what network tier it belongs to). IP addresses cannot be transferred from one pool to another.

The pool of regional external IP addresses in Standard Tier is specific to its particular area, not to the type of qualifying resource. Virtual machine (VM) instances and Google Cloud load balancers that use Standard Tier (external HTTP(S) load balancers, external SSL proxy load balancers, external TCP proxy load balancers, and network load balancers, for example) all use IP addresses from the Standard Tier pool of the selected region.

 

📍Unassigned IP addresses

Unused regional external IP addresses in the Standard Tier act differently from those in the Premium Tier.

When standard Tier IP addresses are not allocated to an eligible resource, they are automatically parked. When an IP address is parked, the load balancer responds to specific requests directed at that IP address; for example, HTTP requests directed at a parked Standard Tier IP address are routed to a Google-hosted HTTP 404 (Not Found) web page. Messages delivered to parked Standard Tier IP addresses are not simply discarded. Furthermore, Standard Tier IP addresses that are being evaluated for assignment to a resource may appear to be parked.You can con visit the official documents of the Setting the default network tier for a project for more information.

APIs and reference 🎯

This section provides information on Google Cloud resources related to Network Service Tiers. See Using Network Service Tiers for techniques and examples.

Compute Engine includes the Network Service Tiers APIs and gcloud commands.

🔖gcloud CLI and API reference

📍Addresses

Creates, edits, and manages internal and external IP address resources that may be allocated to virtual machine (VM) instances and load balancer forwarding rules. Internal IP addresses are always Premium Tier, as are global exterior IP addresses. Regional external IP addresses may be assigned to either the Standard or Premium Tier.

📍Forwarding rules

Used in your Virtual Private Cloud (VPC) network to build, update, and manage forwarding policies. Forwarding rules with an EXTERNAL load balancing scheme establish pathways for traffic to be sent from outside your VPC network to a load balancer or VM instances within your VPC network.

External forwarding rules might be global or localized in nature. The rules for global external forwarding are always Premium Tier. Regional external forwarding rules may employ either the Standard or Premium Tier.

📍Instances

Creates and modifies VM instances in your VPC network.

📍Instance templates

Creates and modifies instance templates. Managed instance groups make use of instance templates. Instance groups are one sort of load balancer backend.

📍Projects

Used to provide the default network tier for resources in a project. This default can be overridden resource by resource.
