Trends in SD-WAN for 2023

According to IDC, SD-WAN infrastructure revenue growth is expected to continue, reaching nearly $7.2 billion in 2026. In 2023, revenues are projected to grow by 17.7% to $5.3 billion.

Drawbacks of SD-WAN

One potential drawback of SD-WAN is the lack of on-site security functionality, requiring additional security standards to be implemented to protect the network from external threats.

Why MPLS Might Be a Better Choice

MPLS offers more control over packet routing and is better suited for real-time applications compared to SD-WAN, which relies on Internet services.

The Hype and Disadvantages of SD-WAN

The marketing hype surrounding SD-WAN can lead to misconceptions, and there is a risk that IT teams become complacent, relying solely on SD-WAN without considering the need for MPLS or dedicated Firewall security.

Is SD-WAN still relevant

As organizations increasingly adopt cloud services, embrace digital transformation, and require efficient connectivity across multiple locations, SD-WAN is likely to remain a prominent solution in the networking landscape.

Does SASE replace SD-WAN

SASE is a next-generation network and security solution that is based upon and incorporates SD-WAN functionality. The two main differences between SASE and SD-WAN are: Security: While some SD-WAN solutions (commonly called Secure SD-WAN) integrate a full security stack, not all do.

What is next-generation SD-WAN

Next-generation SD-WAN is an advanced software-defined networking solution that incorporates modern technologies like artificial intelligence, machine learning and automation.

Is SD-WAN the future

In conclusion, the future of SD-WAN services is expected to continue to evolve, with an increasing focus on cloud-based solutions, enhanced security, automation, AI and machine learning, 5G networks and multi-cloud support.

What is better than SD-WAN

MPLS services often include quality-of-service (QoS) guarantees. SD-WAN leverages best effort Internet services and may experience occasional packet loss. However, most SD-WAN services compensate for this by intelligently steering traffic away from lossy connections. MPLS is better for real-time applications.

What is the trend in SD-WAN in 2023

For 2023, IDC foresees year-over-year revenue growth of 17.7% to $5.3 billion, down somewhat from the revenue growth of 21.5% in 2022. IDC estimates that SD-WAN infrastructure revenue growth will continue with the market reaching nearly $7.2 billion in 2026.

What’s the difference between SASE and SD-WAN

Differences Between SD-WAN and SASE

SD-WAN deals with traffic functions one at a time, case by case, whereas SASE examines traffic overall and provides an overall solution. SD-WAN's security features are secondary, whereas SASE combines a security-focused approach with network optimization.

What is the trend in SD-WAN 2023

For 2023, IDC foresees year-over-year revenue growth of 17.7% to $5.3 billion, down somewhat from the revenue growth of 21.5% in 2022. IDC estimates that SD-WAN infrastructure revenue growth will continue with the market reaching nearly $7.2 billion in 2026.

Why not to use SD-WAN

There is no on-site security functionality. Security standards will still need to be implemented to ensure that your network remains protected and not exposed to outside threats. One simple data breach could compromise the entire enterprise.

Why MPLS is better than SD-WAN

MPLS offers more granular control over where packets go.

Depending on the routing method used, network traffic on an SD-WAN likely will not always take the same route, and some packets may be lost in transit, as is the case with most Internet traffic.

What is the downside of SD-WAN

In many ways, the disadvantage of SD-WAN revolves around the hype. With marketing suggesting a single device is able to perform everything required using almost no deployment involvement, there is a risk that IT teams become complacent believing there is no need to spend on MPLS or dedicated Firewall security.

What will be the hottest network technology in 2023
