Single Cloud Provider SDWAN Deployment vs Multi-Cloud Provider SDWAN Deployment

In today’s modern business landscape, the use of cloud technology has become increasingly widespread. Organizations rely on cloud services to manage and store data, and many businesses also use cloud-based applications to streamline their operations. However, delivering applications from the cloud to remote locations, branch offices, and mobile workers can be a significant challenge. This is where Software-defined wide-area networking (SD-WAN) comes in.

Understanding the Basics: What is SD-WAN and Why is it Important for Cloud Deployments?

SD-WAN is a software-defined approach to Wide Area Network (WAN) connectivity used to connect enterprise networks – including branch offices and data centers – over long distances. It simplifies the management of network infrastructure by separating network hardware infrastructure from the underlying software and the management and control functions from the data plane. In essence, SD-WAN technology offers a way for businesses to connect their remote branches and applications to the cloud and data center without having to rely on traditional WAN technologies or Internet-based VPNs.

SD-WAN is of critical importance for cloud deployments as it significantly enhances application performance and user experience for cloud-based applications. SD-WAN is designed to optimize the use of cloud-provider networks and make them work seamlessly to deliver the best possible application performance. Hence, SD-WAN is becoming increasingly essential in the era of cloud computing as it helps businesses decrease their reliance on expensive T1 lines and legacy WAN connectivity and also lowers the total cost of ownership (TCO).

Another advantage of SD-WAN is its ability to provide better security for cloud deployments. With traditional WAN technologies, security is often a concern as data is transmitted over public networks. However, SD-WAN offers advanced security features such as encryption and firewalls to protect data as it travels over the network. This makes it a more secure option for businesses that rely on cloud-based applications and data storage.

The Pros and Cons of Single Cloud Provider SDWAN Deployment

A Single Cloud Provider SDWAN deployment is a type of software-defined networking deployment that involves the use of a single cloud provider to host business application workflows, virtual machines, and other software infrastructure elements. This type of deployment provides several benefits, such as cost savings due to eliminating or reducing legacy equipment and lower overhead costs. Additionally, it provides a better user experience, since the cloud provider’s network is designed to provide the best possible application performance for the specific cloud environment.

However, Single Cloud Provider SDWAN deployments have some limitations. The biggest concern is that businesses become dependent on a single cloud provider, resulting in one point of failure. In case of a severe outage or data breach, the business could potentially lose access to its data and applications. Another challenge is following compliance and regulatory requirements, where some businesses or government institutions may have constraints on where their data and applications can reside. Finally, vendor lock-in is another potential pitfall, trapping businesses into a specific provider and technology, resulting in significant switching and migration costs if they choose to change providers in the future.

Another potential disadvantage of Single Cloud Provider SDWAN deployments is the lack of flexibility in terms of customization. Since the business is relying on a single cloud provider, they may not have the ability to customize their network infrastructure to meet their specific needs. This can be a problem for businesses that require unique configurations or have specific security requirements.

On the other hand, Single Cloud Provider SDWAN deployments can also provide businesses with a more streamlined and simplified network infrastructure. By relying on a single provider, businesses can reduce the complexity of their network and simplify their management processes. This can be particularly beneficial for smaller businesses or those with limited IT resources.

The Pros and Cons of Multi-Cloud Provider SDWAN Deployment

A Multi-Cloud Provider SDWAN deployment, on the other hand, is a type of cloud networking deployment that utilizes more than one cloud provider to host business applications. The goal of a multi-cloud solution is to have a more robust and resilient infrastructure that can balance workloads and offer better application performance and uptime.

The key advantage of a multi-cloud SDWAN deployment is that it provides more redundancy and resiliency than a single cloud provider deployment. Using more than one cloud provider provides businesses with better options regarding service availability and can help to ensure business continuity regardless of external situations or geographic locations. The multi-cloud environment also gives businesses a certain degree of flexibility, allowing them to select whichever cloud environment is appropriate for a particular purpose or application without relying on a single vendor. Additionally, a multi-cloud deployment makes regulatory compliance more feasible for several organizations by providing more freedom to locate applications and data across different geographic regions in a specific cloud environment.

However, Multi-Cloud Provider SDWAN deployments also have some challenges. The complex, siloed nature of multi-cloud can be complicated to manage and optimize, and interoperability between clouds and workload mobility between clouds can be a significant challenge. Also, a multi-cloud environment can result in higher operational and management costs if not correctly implemented.

Single Cloud Provider SDWAN Deployment: When is it the Best Option?

A Single Cloud Provider SDWAN Deployment is most suitable when the business has a small number of data centers and branch office locations. It would be easier and more cost-effective to use a single cloud provider rather than manage multiple providers. A Single Cloud Provider SDWAN Deployment is also ideal for businesses that need to move data and applications to the cloud rapidly and if they don’t have extensive regulatory compliance requirements.

Multi-Cloud Provider SDWAN Deployment: When is it the Best Option?

A Multi-Cloud Provider SDWAN deployment is the best option when the business has compliance requirements that mandate the use of specific cloud providers. Additionally, if a business has multiple branch office locations and data centers, a multi-cloud environment offers more resiliency and redundancy than a single cloud provider. This deployment would be ideal for large businesses that have complex networking requirements that cannot be met by a single cloud provider method.

Cost Analysis: Which Option Provides the Most Cost Savings?

The choice between Single Cloud Provider SDWAN Deployment and Multi-Cloud Provider SDWAN Deployment depends on the specific business requirements. Single Cloud Provider SDWAN Deployment is the best option for businesses that have lower networking requirements and don’t need to meet regulatory compliance standards. In contrast, Multi-Cloud Provider SDWAN Deployment can provide more resiliency and flexibility, but it comes with higher operational and management costs.

It’s worth noting that businesses must compare the TCO of both options before choosing a cloud provider. The TCO of Multi-Cloud Provider SDWAN deployment can be more expensive than a single cloud provider. In addition, businesses can save costs in a Single Cloud Provider SDWAN deployment by consolidating network infrastructure and reducing overhead costs such as maintenance, licensing, and support costs.

Security Considerations: Is Single or Multi-Cloud Provider SDWAN Deployment More Secure?

When it comes to security, both Single Cloud Provider SDWAN Deployment and Multi-Cloud Provider SDWAN Deployment have their unique set of challenges.
