Cloud Network Architecture- An Introduction In 3 Easy Points

Introduction

Technology has grown by leaps and bounds, and so the organizations reap the benefits of the changing infrastructure for availing better services to scale up their business. A cloud network aims at achieving automated replacement of components, process distribution and achieving resilience. A cloud network should be designed in such a way that it supports and handles all the necessary services.

This is often challenging as many companies do not have a ready underlying infrastructure. With the advancement in science and technology, there are multiple options for various network designs depending on one’s requirements. Cloud computing has evolved in a shorter span, thus offering greater better alternatives.

Cloud computing is used by all sizes of companies for storage and access to data and information on a real-time basis. Cloud networks help in the design, management, and configuration of the network. This is done in a private or public cloud. Private Cloud is more feasible as the whole management, configuration, and design of the underlying infrastructure is handled by the cloud provider. For Public Cloud, the handling, managing, and controlling of the networking are only in IaaS deployments.

The cloud service providers have full control over SaaS and PaaS, and hence customers cannot control such functions. A combination of Private and Public Clouds is also available- Hybrid Clouds. In a Hybrid Cloud, some functions are controlled by the company themselves, and some are with the IaaS provider infrastructure.

1. What is a cloud network?
2. What cloud network architecture options are available?
3. How do you choose cloud network architecture?

1) What is a cloud network?

Cloud networking is playing a crucial role in addressing the organization and it is infrastructural needs, geographic expanse and other plans like redundancy. They even aim for higher scales and getting real-time data on a constant and dynamic basis. 

A cloud network is an IT infrastructure wherein some or all organization’s network resources and capabilities are hosted. These can be public, private or hybrid platform. A cloud network can be managed in-house, available on-demand or by a service provider. 

Organizations can use on-premises cloud networking resources for building a private network. They can even use the public network on cloud-based networking resources. Also, it should be kept in mind that the network design supports all the relevant applications, information and services.

2) What cloud network architecture options are available?

Companies have three cloud networking architecture, as outlined under:

1. Built-in networking tools: These tools are the ones that are readily available as a part of the IaaS service. This aids in the independent configuration and management of the IaaS cloud of any public or private cloud. So here, basic access is easily provided.

2. Virtual networking applications: A networking vendor offers his services for the management of networking tasks. This all is done virtually. Some of them include virtualized routers, firewalls for sale on IaaS. Popular companies offering them are Cisco, Jupiter, SonicWall.

3. Multi-cloud management platform: This is a complex option. They are created to overlay between the private and public cloud. This aids in the distribution of networks across many public cloud providers. 

3) How do you choose cloud network architecture?

Depending on the short-term and long-term needs, one should choose cloud network architecture. It can be in-house, available on-demand or by a third-party service provider. Many companies decide on hybrid architecture with a single provider. This can be a third party or built-in. Some companies may need vast distributed multi-cloud ambition, so in that case, a multi-cloud management platform would be considered. 

Also, considering the requirements of long-term IaaS or SaaS, one should make a decision. It has been predicted that SaaS will surpass IaaS and PaaS. So companies should think of the long term and consider the forecasts as well.    

Conclusion

With the dynamic changes in information technology, the need for robust implementation of the various services offered is a must. Cloud Computing is one such field where new ways and methods are incoming at a fast pace. Hence, the underlying architecture is also adapting and paving its way for better compatibility. With this, there are high chances for the definition of cloud computing and its architecture to change. 

Organizations want to constantly take benefit of the feasibility and choice of the best cloud offering. Certain things should be kept in mind as the business efficiency should improve, and the data should be highly secure. They should look for a comprehensive cloud management solution offering all the strategies in one place.

Cloud Computing Architecture aids in improving data processing requirements. It also results in scaling up the cloud resources as well as automatic updating of its services. One of the best features is the ability to cope up with a disaster as it provides a high level of security. With these clients also feel that their data is secure, providing them with a better environment to work with services accessible over the internet.
