When a network is “managed,” it means that someone is actively taking care of it. In this context, managed Software Defined Wide Area Network (SD-WAN) is a concept that offers end-to-end ready to use network solutions that can be implemented on an existing network infrastructure by organizations or branch offices quickly and easily. It functions as an ever changing structure to multiple connections for a better bandwidth. However, in addition to Managed SD-WAN, there is another approach, which is the do it yourself (DIY) SD-WAN. Through this post, we will give a detailed explanation of both methods and considerations to take note of.
DIY SD-WAN vs Managed SD-WAN
A Do it yourself (DIY) SD-WAN just like the name implies is an enterprise that will require a hardworking and committed team to install, control and look after the SD-WAN solution by itself. A managed service provider (MSP) on the other hand is a service provider that installs, controls and looks after an SD-WAN solution for an organization, while the IT staff can focus on other valuable projects. In essence, DIY SD-WAN is an in-built solution that requires enterprises to purchase, install and maintain their own hardware and software while Managed SD -WAN deploys and manages WAN enterprise to a third-party service provider..
DIY SD-WAN has full power and control over all aspects of the service since it operates in the enterprise itself. However, It has slower integration of new sites, time to market and upgrade as juxtaposed to Managed SD-WAN which has less control over all aspects of the service. It is also distinguished with faster integration to new sites, time to market and upgrade.
Comparison between DIY SD-WAN vs Managed SD-WAN
| DIY SD-WAN | Managed SD-WAN | |
| Cost | Requires significant in-house networking and IT expertise to design, implement, and manage. | Less in-house expertise required as the service provider manages the network. |
| Setup | May take longer to implement due to the need for in-house setup and configuration. | Faster implementation as service providers use standardized processes. |
| Performance | In-house teams must continuously monitor and optimize network performance. | Service providers offer continuous monitoring and optimization as part of their service. |
| Security | Security is managed internally, requiring dedicated resources to stay updated on threats. | Service providers typically include advanced security features and regular updates as part of their service. |
| Technology Updates | Organizations need to stay updated with the latest technologies and implement them. | Service providers manage technology updates and ensure the network uses the latest advancements. |
| Customisation | Organizations can fully manage the deployment and tailor configurations to fit their specific requirements. | Service providers manage the implementation by providing pre-defined settings and minimal customization options. |
Most preferred installation method
Businesses frequently opt for managed SD-WAN as it streamlines network administration by delegating it to skilled service providers. This enables businesses to concentrate on fundamental tasks instead of overseeing the intricate network infrastructure, which they lack the required expertise for. Managed SD-WAN provides expert knowledge, ensuring fast problem-solving and access to updated technologies. While the initial expense may be greater, it results in cost savings in the long run by decreasing the requirement for internal IT personnel. Furthermore, it offers improved security, ongoing performance optimization, and the ability to scale with business expansion. Quick implementation, consistent technology upgrades, streamlined operational processes, and assurance of reliability via service level agreements (SLAs) also contribute to the appeal of managed SD-WAN for businesses.
Considerations for choosing SD-WAN services
Innovation
WANs function differently from other data center networks. SD-WAN service providers understand how they operate. Consider choosing a SD-WAN service that has mitigated network issues like latency or packet loss and have adequate plans for future digital changes. Choose an SD-WAN service provider that has secure plans for the future because SD-WAN technology is structured to evolve over the years
Cost
Cost effectiveness of SD-WAN is crucial for businesses. It is important to choose a SD-WAN service provider that supports different types of connections in order to optimize SD-WAN usage and cost. Make sure that the cost usage is as it should be and never pay high for a poor performance.
Security
One of the most important things when choosing a SD-WAN service is the matter of security and it is important to give it considerable thought. While SD-WANs comes with some features like the data encryption to protect against possible threats, it would be wise to choose a service that has integrated some solutions like; next-generation firewalls, anti-malware, intrusion prevention system (IPS) and so on for a tighter security
Flexibility
When selecting SD-WAN and struggling to make do with little resources, choose an SD-WAN service provider that uses a dynamic path to ensure the distribution of the network across various branches. Choose a network path that does the work you require while also having a variety of options to pick from.
Bandwidth
Network bandwidth determines the data transfer capacity of a network, which is why it is important to consider the bandwidth of the SD-WAN service provider you want to choose— against now and in the future. The bandwidth will go a long way in measuring the efficiency of an organization, both on-site and remotely, therefore be careful in selecting which service providers will work best for you.
The Future of Managed SD-WAN
There is strong evidence that SD-WAN is necessary as cyberattacks continue to grow rapidly. MPLS is gradually becoming obsolete, and without an SD-WAN solution, the rise in data flow from devices is likely to decline. However, the future of managed SD-WAN is promising. Replacing traditional WAN with SD-WAN will improve performance for organizations. Additionally, government agencies and organizations are increasingly focusing on preventing cybercrime, which continues to evolve. With the growing demand for security, next-generation SD-WAN will depend on supporting technologies.
