What is Cloud Networking?
Cloud networking refers to the utilization of cloud computing principles to create, manage, and optimize networks. It encompasses a range of services and technologies that leverage the cloud’s scalability, flexibility, and cost-effectiveness to enhance traditional networking functionalities.
Cloud networking is an element of cloud computing and refers to the way the networking infrastructure works within it. Cloud computing has revolutionized the way companies run, making it easier, faster and cheaper to complete functions that previously required a company to have its data centre. Almost every type of business today uses cloud computing for a wide range of purposes, including data backup, email and customer-facing web applications.
Why Cloud Networking?
Businesses today turn to the cloud to drive agility, deliver differentiation, accelerate time-to-market, and increase scale. The cloud model has become the standard approach to building and delivering applications for the modern enterprise. Cloud networking has also played a critical role in the way organizations address their growing infrastructure needs, regional expansions, and redundancy plans. Cloud networking is one where all the network resources are in the cloud environment. Cloud networking is a technique of resource sharing where the resources are:
- Servers
- Storage
- Other computing resources
Companies nowadays use the cloud to boost scale, drive agility, create differentiation, and improve time-to-market. For the corporate entity, the cloud model has evolved into the de facto method for creating and distributing applications.
Why is it Required?
Modern businesses require an agile network that can provide faster computing solutions. Cloud networking offers a computing solution that can be monitored and managed remotely. With this, the computing solutions it offers are fast and secure.
Cloud networking leveraged organizations to increase their computing infrastructure, regional expansions, and data redundancy plans. So, many companies, organizations, and enterprises are nowadays opting for cloud networking.
Functions of Cloud Computing
In general, the cloud is a distributed space where information can be exchanged over satellite systems. Every cloud application needs a host, and that institution manages the enormous data centres that offer the security, storage space, and computational power required to keep all user-submitted data in the cloud.
These hosting firms can charge customers for the use of their clouds and the storage of data on their networks while simultaneously providing an environment that allows devices and software to talk with one another.
How Cloud is Changing Traditional Networking
Cloud networking is continuously evolving and creating new challenges for network architects. The main concern of every network user is that they can have reliable, fast and secure access to the application or data they use daily.
Traditional Networking is secure because the data owner has complete control over it and its transmission. But for the traditional networking model, we have to purchase the entire setup for Networking, such as hardware & software, and update them regularly. Buying and maintaining the entire setup can be tedious even for the big companies with skilled IT teams.
Examples of Cloud Services include
- Software as a Service (SaaS), which gives companies access to applications as a subscription.
- Infrastructure as a Service (IaaS), which provides virtual computers over the internet, including virtual machines, networks, computers and other resources.
- Platform as a Service (PaaS), which makes it possible to develop and run applications without the complexity of infrastructure management.
- Machine Learning as a Service (MLaaS), offers cloud-based platforms and APIs that enable developers to build, train and deploy machine learning models.
Cloud networking capabilities are provided by the cloud service providers.
Types of Cloud Networking
There are various types of cloud networking. Here are the main ones:
Based on Deployment
- Public Cloud
A public cloud means that the servers are being shared by other people. You might think of a public cloud as similar to a public swimming pool. This type of cloud is adjustable to different capacities of a company’s IT department. Multiple users may be using a public cloud but will all be able to benefit from the service.
- Virtual Private Cloud (VPC)
While a public cloud is like sharing a pool, a virtual private cloud (VPC) is more like putting a rope around the pool and creating a private area. Companies can choose to build their own private cloud within a public cloud. Increased security is the main reason a company would choose a VPC.
- Hybrid Cloud
Hybrid cloud refers to the combination of public clouds and VPCs. The term hybrid cloud network is also used to refer to the connection between a physical data centre and a public cloud.
- Multi-cloud
The term multi-cloud refers to using more than one cloud provider. For example, a company might choose to use services both from AWS and Microsoft Azure. While they both offer cloud computing, they do have differences. A company may find the differences between the two providers make it worth it to use both.
Based on Service Model
- Infrastructure as a Service (IaaS) Networking
IaaS providers offer networking components such as virtual networks, firewalls, load balancers, and VPNs, allowing users to build and manage their network infrastructure on the cloud.
- Platform as a Service (PaaS) Networking
PaaS solutions offer networking tools and services as part of their platform, enabling developers to build, deploy, and manage applications without worrying about the underlying network infrastructure.
- Software-Defined Networking (SDN)
SDN decouples the control plane from the data plane, allowing for centralized management of network traffic and configurations. It provides flexibility, automation, and programmability in network operations.
- Network Functions Virtualization (NFV)
NFV virtualizes network functions, transforming them from hardware appliances to software-based instances. This enables easier scalability, agility, and cost-efficiency in deploying network services.
Benefits of Cloud Networking
- Scalability and Flexibility
Cloud networking offers on-demand scalability, allowing businesses to easily scale their network resources up or down based on fluctuating demands without significant infrastructure changes.
- Cost-Efficiency
By eliminating the need for expensive hardware investments and allowing pay-as-you-go models, cloud networking reduces capital expenditure and offers cost-effective solutions.
- Improved Performance and Reliability
Cloud networking often leverages distributed infrastructure and redundancy, leading to enhanced performance, reduced latency, and improved reliability compared to on-premises setups.
- Centralized Management and Automation
Centralized management tools in cloud networking simplify network configuration, monitoring, and maintenance. Automation capabilities streamline operations, reducing manual intervention and potential errors.
