Cloud networking is a type of networking technology that uses cloud computing to manage, operate, and deliver network services and resources to users over the Internet.
In cloud networking, network resources such as servers, switches, routers, and firewalls are hosted and managed in the cloud rather than on-premises. This allows enterprises to easily and cost-effectively deploy and manage their network infrastructure, as well as scale up or down their network capacity as needed.
Whilst today’s environment is becoming more competitive than ever, cloud networking has become a key technology for enterprises looking to build a scalable, flexible, and cost-effective network infrastructure that can meet the demands of today's digital economy. By leveraging cloud networking, businesses can better manage their network resources, improve performance and security, and ultimately drive business growth and success.
Cloud networking has become increasingly popular in recent years due to its numerous benefits. Here are some of the key advantages of cloud networking:
Cloud networking allows enterprises to easily scale up or down their cloud network infrastructure to meet their changing needs, which is not possible in on-premises environments. IT resources can be adjusted quickly, such as adding network capacity instantly or deactivating IT resources based on lower demand.
Cloud networking can be more cost-effective because it eliminates the need to invest in expensive networking equipment. Instead, cloud networking services are often charged on a pay-as-you-go basis, which can be more affordable and easier for budgeting.
Cloud networking offers flexibility and mobility from network resource management, access and permission control, to individual end-user experience. Cloud networking services allow greater visibility and flexibility to network management, which is more suitable for today’s distributed enterprise and remote work.
Cloud networking is one type of network infrastructure that utilizes cloud computing technologies to provide high-performing network solutions for enterprises. The basic elements of a cloud network include:
Cloud infrastructure, the foundation of cloud networking, includes the servers, storage, and networking components that are used to provide cloud-based services. Cloud infrastructure is often hosted and managed by cloud service providers.
A VCN is a virtual network that is customizable in a cloud service provider's infrastructure, enabling enterprises to securely connect their cloud infrastructure, applications, and services. VCNs can be customized to meet the unique needs of each business and can include features such as subnets, security rules, and routing tables.
Cloud-based firewalls can help protect businesses against cyber threats and ensure compliance with industry regulations. It can be configured to monitor network traffic, filter out unwanted traffic, and block unauthorized access to cloud-based resources.
Cloud networking solutions typically provide monitoring and management tools that allow enterprises to monitor their network infrastructure, track performance, and troubleshoot.
Cloud network architecture refers to the design and structure of a network infrastructure that is used to deliver cloud services, and there are mainly 3 available choices:
|Virtual Cloud Network||Software-based and runs on top of physical hardware||Highly scalable and flexible||Can be deployed across multiple cloud environments and data centers||Requires manual configuration and management|
|Built-in Cloud Network||Integrated into a cloud service provider's platform||Highly scalable and automated||Deploys and manages applications and services without having to worry about underlying network infrastructure||Automated, requires minimal manual configuration and management|
|Hybrid Cloud Network||Combines both public and private cloud environments||Provides the benefits of both public and private clouds||Requires careful planning and integration||Requires manual configuration and management|
A virtual cloud network architecture is a network infrastructure that is entirely software-based and runs on top of physical hardware. It enables businesses to create a virtual network that spans across multiple cloud environments and data centers. Virtual cloud networks are highly scalable and flexible, making them an ideal choice for businesses that need to deploy and manage applications and services quickly.
A built-in cloud network architecture is a network infrastructure that is integrated into a cloud service provider's platform. Built-in cloud networks are designed to provide a seamless experience for users, allowing them to deploy and manage their applications and services without having to worry about the underlying network infrastructure. Built-in cloud networks are often highly automated, making them ideal for businesses that need to scale their operations quickly.
A hybrid cloud network architecture is a network infrastructure that combines both public and private cloud environments. Hybrid cloud networks enable businesses to leverage the benefits of both public and private clouds, allowing them to maintain control over critical data and applications while also taking advantage of the scalability and cost-effectiveness of public cloud resources. Hybrid cloud networks require careful planning and integration to ensure that they are secure, reliable, and performant.
Depending on their specific needs and requirements, businesses can choose from different types of cloud network options, out of which the 4 main types of cloud networks are public cloud, private cloud, hybrid cloud, and multi-cloud.
A public cloud network is a cloud environment that is offered by a third-party cloud service provider and is available to the general public over the Internet. Public clouds are typically highly scalable and cost-effective, making them an ideal choice for businesses that need to quickly deploy and manage applications without investing in expensive infrastructure.
A private cloud network is a cloud environment that is dedicated to a single organization and not shared with others. Private clouds are typically more secure and customizable than public clouds, making them an ideal choice for businesses that require a high level of control over their data and applications.
A hybrid cloud network is a cloud environment that combines both public and private cloud environments. Hybrid cloud enable businesses to leverage the benefits of both public and private clouds, allowing them to maintain control over critical data and applications while also taking advantage of the scalability and cost-effectiveness of public cloud resources.
A multi-cloud network is a cloud environment that leverages the services of multiple cloud service providers. Multi-cloud networks allow businesses to avoid vendor lock-in and take advantage of the unique features and capabilities offered by different cloud providers. Multi-cloud environments can be either public, private, or hybrid, depending on an organization's specific needs and requirements.
Cloud network solutions can be used in a variety of use cases to help businesses achieve their specific goals and objectives. Here are some common use cases for different cloud network solutions:
SaaS is a cloud-based delivery model for software applications. It enables businesses to access software applications over the Internet without having to install and maintain them on their own servers. SaaS solutions are commonly used for collaborative tools (e.g. business email and video conferencing), productivity tools, customer relationship management (CRM), and other business applications.
IaaS is a cloud-based delivery model for computing resources such as servers, storage, and networking. It enables businesses to rent computing resources on-demand and pay only for what they use. IaaS solutions are commonly used for hosting websites, running applications, and managing large data sets.
PaaS is a cloud computing model that provides development and deployment environment for building, testing, deploying, managing, and updating applications. With PaaS, developers can purchase pay-as-you-go access to everything they need to build custom apps, including infrastructure, middleware, development tools, and more, without the hassle and cost of installing hardware or software.
BaaS is a cloud-based solution that enables businesses to backup and store their data securely in the cloud. BaaS solutions provide an easy and cost-effective way to protect critical data assets from loss, theft, or corruption. BaaS solutions can be used for both onsite and offsite backup, allowing businesses to store their data in a variety of locations for added redundancy and resilience.
DRaaS is a cloud-based solution that enables businesses to quickly recover their IT infrastructure and data in the event of a disaster such as a natural disaster, cyberattack, or hardware failure. DRaaS solutions provide a cost-effective and reliable way to ensure business continuity in the face of unexpected disruptions. It is often worked with BaaS to provide a total solution for backup and recovery services.
