A specialist’s guide to your SD-WAN journey

Using SD-WAN correctly: The key to digital transformation

Why strategy, network quality and choice of provider are crucial

Many companies are in the midst of digital transformation – and are encountering a familiar problem: the network is slowing down cloud performance, hampering innovation and causing unnecessary costs. SD-WAN is seen as a solution – but without the right strategy, its introduction can fail.

Typical challenges on the way to a successful SD-WAN implementation:

The question:
How can companies successfully introduce SD-WAN – as a driver of digital transformation, not as a stumbling block?

When talking about digital transformation, the path quickly leads to networks – and therefore to SD-WAN and cloud applications. No wonder: networks are crucial for the performance of modern applications that are increasingly operated in the cloud. It is precisely these applications that are at the heart of digital transformation – they ensure innovative strength and competitive advantages.

Cloud has changed the network paradigm

As applications moved from the data center to the cloud, traditional hub-and-spoke network architectures became less important.

SD-WAN was introduced. Companies realized that they could use different transmission types such as 4G/5G and the Internet with MPLS, orchestrate them with SD-WAN and reduce transmission costs at the same time.

SD-WAN’s software-based approach to network management promised to solve a number of problems. However, experience shows that this is often not the case.

SD-WAN Box should be last on your list

SD-WAN and its up-and-coming successor, the SASE framework, are the future of networking. But your network is made up of several moving parts. Before you deploy either technology, you should consider how the rest of your network environment can support it.

Most importantly, your business goals must come first. No two companies have the same needs, so a one-size-fits-all approach will not deliver the best results. Define your business requirements and then deploy the right technology solution.

Below are some of the key points to consider before implementing SD-WAN to support digital transformation.

Insist on the choice of technology

You will probably not set up SD-WAN yourself. You will rely on the expertise of a third party.

This approach has its pitfalls. Vendors recommend their own devices, and most integrators recommend the vendors they are connected to. The problem is that different SD-WAN/SASE-led solutions have different levels of performance. The technologies offered by the vendor or integrator may not fully support you. But that’s all you’re going to get, because that’s all they’re selling.

Savecall ensures that you receive manufacturer-independent advice. And, above all, that you are familiar with the entire range of provider technologies. However, most integrators are only familiar with a few technologies or refer to a few providers.

Savecall and its partners, on the other hand, have expertise in most major vendors and technology areas for medium and large enterprises. As a result, we can put your business objective first and then match the technology to it – and that’s how it should be.

Check the quality of the network connections.

The performance of an overlay technology such as SD-WAN ultimately depends on the strength of the networks over which it runs – or the underlay. Several networks are involved in the underlay.

The core network. Performance is highly dependent on the quality of the core network, which should have a high capacity and multiple fail-safe paths.

Internet. Direct internet access is now the preferred method of connecting users to the cloud. However, some internet providers offer shared services, so check what you’re getting into. The other option is to use dedicated internet access, which provides a dedicated, unattended internet connection with guaranteed bandwidth.

Mobile. With the introduction of 5G, mobile technologies are being used, both as a backup and as the main connection. But coverage is the be-all and end-all.

Check how everything is connected

Good core networks are only one side of the coin. Just as important is how the network is connected to the functions you use every day.

Most companies today use one or more public clouds. The peering links between these cloud providers play an important role in network performance. The more connections your network provider offers and the closer they are to clouds and other networks, the fewer hops users have to make to get to their applications.

Peering links therefore have an impact on the functionality of applications and ultimately on productivity as well as the user and customer experience.

Will you be flexible for business?

Regardless of your SD-WAN solution, you need to buy connectivity. However, with some providers, you are locked into bandwidth, access types and pricing. This can prove to be a stumbling block in an evolving application landscape, especially as your digital transformation progresses. It pays to choose a network provider that offers flexibility.

SD-WAN and digital transformation

SD-WAN is an important part of digital transformation. But it is only one part of many, and most of them are interlinked.

When considering these technologies, it pays to have a partner who has the big picture in mind. A partner whose skills not only cover the entire technology area, but also incorporate your entire business strategy. This makes it easier to achieve your transformation goals.

Savecall is that partner.

From discontinued model to future solution

VPN as a discontinued model?

During the pandemic, VPN access was quickly ramped up. But VPN was never designed for widespread remote access.

Problems with VPN:

  • Limited licenses
  • Unstable connections
  • High administrative costs

This is where SASE (Secure Access Service Edge) comes in. The cloud-native architecture combines network functions with integrated security and is increasingly competing with traditional VPNs.

Rethinking IT infrastructure

The demands placed on companies have changed. Customers, employees and processes expect the same today:

  • Personalization
  • Security
  • Sustainability
  • Flexibility

This also increases the demands on the network infrastructure:

  • Introduction of SD-WAN for more control and better connectivity
  • Introduction of UCaaS solutions such as Microsoft Teams or RingCentral
  • Rollout of IoT applications and smart devices
  • Securing home office environments with Zero Trust and SASE

Why SASE is the better VPN alternative

Compared to VPN, SASE offers many advantages for the modern working world:

  • Scalability: grows with you, no matter how many remote workstations are added.
  • Security: Zero Trust architecture, access policies and integrated protection against cyber attacks.
  • Performance: intelligent routing via local nodes.
  • Ease of use: simple setup, consistent user experience everywhere.

In a nutshell:

  • Future-proof replacement for VPN
  • Sustainably optimized remote access
  • More security, better performance, greater flexibility

Today, the home office is often the entry point for cyber attacks:

  • Private devices
  • Unprotected networks
  • Lack of IT control

SASE protects exactly where conventional VPNs reach their limits.

Companies must take responsibility > together with their employees.

Cybersecurity starts at home.

Conclusion: SASE is more than just a VPN replacement

SASE is not just another security feature, it is a new way of thinking. For companies that want to make their infrastructure future-proof, secure and scalable.

SASE makes hybrid working safe, efficient and flexible.
Now is the right time to make the switch.
