Google Cloud Platform Networking Services

Last Updated : 11 Dec, 2024

Google Cloud Platform offers a suite of networking services that can help you manage and build complex network architectures, reduce network latency, and simplify network administration. To learn more about the GCP Networking Services, read on!

GCP Networking Services offers IP transit service in peering locations around the world. You can also create your own private connection. GCP Networking Services have a rich set of networking tools that allow you to design networks using APIs or Cloud Console or CLI commands for advanced use cases like configuring firewall rules.

Cloud Networking

Google Cloud Networking which is used to connect the different resources available in the cloud together to the internet following are the some of networking services offered by the GCP(Google Cloud Networking).

Virtual Private Cloud (VPC).
Subnets.
Firewall rules.
Load balancers.
VPNs.

What is a Subnet?

When a bigger network is divided into smaller networks, to maintain security, then that is known as Subnetting. So, maintenance is easier for smaller networks. For example, if we consider a class A address, the possible number of hosts is 224 for each network, it is obvious that it is difficult to maintain such a huge number of hosts, but it would be quite easier to maintain if we divide the network into small parts. To Know more about sub-netting refer to Introduction To Subnetting.

Benefits of Subnet

Dividing the network into smaller networks will improves the performance which will reduce the latency of the application by reducing the follow of traffic between the networks.
Improves the security of the applications by dividing the network into sub net which will isolate the one subnet form another which will reduce the security threat of different applications.
Scalability of the application is very easy instead of redesign the entire network you can just scale the network you want to scale by using the subnet option.

What are Firewall Rules and Why are They Important?

The network traffic of the virtual machine in the GCP is controlled by the firewall rules. Firewall rules will allows you to specify the IP address and ports which you want to allow to the virtual machine. Which will restricts the unauthorized access of to the virtual machines.

Why use Regions and Zones?

In Google Cloud Platform regions are The Region is a Specific geographical location to host your applications. Each region is designed to comply with specific laws and regulations and to provide low-latency network connectivity to specific geographic areas and zones are small isolated areas of that regions.

Reasons to use Regions

If you want your application to be more available then you need to deploy it in the regions and zones and this where actual data centre of the cloud will be located.
In a region there will be multiple availability zones which are used for disaster recovery purpose.
The zones which are available in the same region are inter connected with each other.
The data which is more important to the organization will be stored in the multiple zones of an single region.

Virtual Private Cloud (VPC)

Resources offerd by Google Cloud Platform can be isolated with the help of Virtual Private Cloud. You can manage the access to GCP resources which are deployed in the VPC by configuring the IP address which can allowed to access the resources.

Importance of VPCs in GCP

You can isolate the resource which are in GCP from one another.
You can control the access to the resource by allowing the incoming and outgoing traffic.
Scaling of the application can be done very easily.

Load balancers in Google Cloud

Load balancing is a service that allows you to distribute your traffic across multiple servers so that one server does not become overburdened. An example of this would be if all of your customers were on the same network with hundreds of requests coming from them at a specific time. If you had only one server handling this traffic, it would quickly become overwhelmed and unable to handle the request load. Load balancing allows you to distribute the traffic evenly across multiple servers so that one server does not become overburdened. There are two types of load balancing:

Network load balancers do not hash the IP address of each request. Instead, they know what the IP address is for each server in the pool and in turn, send that request to that specific server. If no servers are available, then either a new server will be elected or requests will be rejected due to the inability to handle the load. Network Load Balancers (NLB) only support HTTP or HTTPS and have some other limitations such as a maximum size of 50,000 requests per second (RPS).

Distributed Network Load Balancers (DNLB) utilize a hash algorithm such as the Secure Hash Algorithm 3 (SHA-3). DNLB supports TCP, HTTP, HTTPS, SMTP, and POP3. The possibilities are endless when it comes to the types of applications that can be supported with DNLB.

There are a couple of ways to implement this service. You can have your entire infrastructure behind one instance for both load balancing and DNS/DHCP services. There will be a single IP address for you and any DNS that needs to be used can be provided from that one IP address as well.

GCP Components and Fundamentals

The following are some components of GCP:

Load balancing: To distribute the workload uniformly across a group of servers by distributing the load and responses to each server in the group.
Cluster: A collection of nodes that work together as a single unified computing resource.
Area (Zone): Isolation of resources for different customer types, their operational requirements, or regulatory restrictions.

Virtual Private Networks (VPN)

A Virtual Private Network (VPN) is a network of computers that have a connection to the Internet, but they appear to be located outside the network and may use this virtual location to conduct their business. VPNs are widely used by organizations, corporations, and others who want security and anonymity on the Internet.

There are many reasons why you might want an encrypted virtual web portal on the internet that serves as an anonymous entry point into your computer network: online banking transactions, software piracy/illegal downloads, and streaming services.

Dynamic DNS

A Dynamic Domain Name System (DDNS) is an Internet service that allows one computer to have a stable, easily remembered name that is automatically updated without requiring any action from the user. Dynamic DNS creates a temporary name for a computer or device, which is then replaced by the real IP address at a later time. For example, if you connect to your own home network, you can set up dynamic DNS on your router to allow you to access your home computer's files and networks whenever you want.

In order for this to work, your router must be set up to point to the Internet, and your computer or device must be equipped with a dynamic DNS client.

The client (computer or device) sends a registration request command to the Dynamic DNS server. The Dynamic DNS server responds with the requested information.
The client contacts the Dynamic DNS server with an IP address in order to update its name. If the information has not changed since registration, then no action is necessary.

To meet this need for high-performance computing (HPC), GCP Networking Services offer the service Cloud Dataflow which is a service for processing data in a streaming fashion. Cloud Dataflow provides a declarative programming model for building processing pipelines, as GCP Networking Services as machine learning libraries and inference models with support for custom data sources and destinations. Cloud Dataflow is Google's first framework for streaming data.

Cloud Datalab

Some Key points of Cloud Datalab are listed below :

It is a self-contained programming environment for querying and analyzing large-scale datasets stored in the Cloud through a unified user interface. Cloud Datalab leverages the poGCP Networking Services of BigQuery, the Google Cloud Platform data warehouse, which enables you to store, query, and analyze petabytes of structured and unstructured data at incredible speed.
Cloud DNS allows you to configure domain names for your applications with our globally distributed network of public DNS server infrastructure. You can also use our name server service to manage multiple domains from a single UI by using Cloud DNS' delegation feature. Cloud DNS offers rich functionality and a flexible API, allowing you to support many different use cases, including private and public hosting environments, traffic management, SSL certificates, and more.
Cloud Load Balancing allows you to expand the capacity of your applications with a globally distributed network of edge locations. You can spread incoming user requests across different regions and Availability Zones within your network. This helps speed up access times for users worldwide.
Cloud Logging is an analytics service that allows you to collect, store, and retrieve log data for debugging or monitoring purposes. With Cloud Logging, you can view logs in the cloud console or programmatically analyze them using the Google Stackdriver Logging API.
