The software-defined wide area network is designed not only for the current but also the future needs of the organization. In addition, it can help reduce your overall bandwidth costs.

Analysts estimate that about 30% of companies are already using public cloud services; the volume of their use will increase annually by 17%.

In addition, the proliferation of mobile versions of enterprise applications is increasing; they become available on various devices outside the office. This is a very important trend, given the fact that in 2018 half of all employees in the corporate sector will use mobile devices. Networks have become a strategically important asset for companies, and therefore IT leaders must plan for alternative methods of connecting mobile devices in corporate wide area networks.

The communication requirements of companies have outgrown the capabilities of private WAN MPLS services to provide communications between remote offices and data centers. The current network architecture, which is more than ten years old, does not meet today's requirements: an increase in the number of connected devices, mobility, increased security needs. The software-defined wide area network (SD-WAN) is designed not only for the current needs of the organization, but also for the future. SD-WAN technology allows you to create hybrid networks that combine access technologies such as Internet services, dynamic traffic routing and real-time connection configuration based on available bandwidth or selected criteria. Besides,

In 2015, the emerging SD-WAN market was estimated at almost $ 225 million.According to IDC forecasts, in 2016 this market will grow by 165% to $ 595 million. Then in 2017 - by 129%, in 2018 - by another 87%, reaching 2.6 billion. According to analysts, by 2020 the average annual growth rate of the SD-WAN market will be 93%, which will allow it to reach more than $ 6 billion.

When it comes to setting up effective, efficient networks, the help of an expert is essential. Versa SDWAN Engineers are specialized IT professionals that help with just that, primarily by helping to implement, optimize, and manage SDWAN networks.

Enterprise-level businesses, especially those aiming to evolve their tech and keep it up-to-date, are looking for network specialists to help them create the best networks possible. Versa SDWAN Engineers often find work internally as part of an organization’s IT team or with network providers, helping to sell and optimize networks for a range of different clients.

There are a number of factors to keep in mind when you are deciding whether to deploy SD-WAN and how to best go about it.

For example, would you prefer to manage it in-house or do you want it delivered as a service? Compared to managing it in-house, getting it delivered as a service is much faster to deploy and the provider will also manage it for you, so it may be more convenient.

Also, consider whether to use an internet-based SD-WAN deployment or a global private network. Internet-based might be enough for your organization if your branches are in a local area and the internet is of a high quality, but it could bring issues for global SD-WAN deployments. In this case, you might want a global private network that provides a faster response time and increased security. 

Consider all the factors that will affect your decision when deploying SD-WAN. These include the size of your business, the locations of your branches, and how you will manage the network, all of which have an impact.

Spend time reviewing your current system to find out if deploying SD-WAN will be worthwhile. In many cases it is, but it is not always the best solution for every business, so you need to closely analyze your setup and work out the cost and productivity savings.

Obviously, increased reliance on SD WAN Services from cloud service providers has major implications for SD-WAN platform vendors and their managed service provider (MSP) partners. MSPs will need to find way to augment the SD-WAN cloud service in a way that continues to make them relevant to their end customer. Providers of SD-WAN hardware will need to find ways to deliver software that extends the core capabilities of an SD-WAN service. In some cases, IT teams are even deciding the path of least resistance to accessing applications in a local data center is to reverse backhaul traffic via a cloud service provider.
As usage of SD-WAN evolves, it’s clear MSPs will need to find ways to adapt. There may still be plenty of instances where SD-WAN appliances might be deployed in an on-premises IT environment. However, it’s clear MSPs need to adapt to some new SD-WAN realities or quite possibly perish.

MPLS never got the memo about the speed of business changing, because adding new locations can still take weeks, if not months. With SD-WAN, new locations can be brought up in days. What’s more, Aryaka’s Global SD-WAN encrypts traffic end-to-end, which isn’t offered with MPLS and may be an important compliance consideration.

Speed up your applications no matter where they are hosted. An SD-WAN, with built-in WAN optimization, improves performance for all mission-critical applications, hosted on-premises or in the cloud. And if you choose an SD-WAN delivered as a service over a private network, you can realize consistent application response times for users anywhere in the world, and sidestep the performance problems that plague SD-WANs that use Internet transport.

After being a security partner for SD-WAN vendors, Palo Alto Networks is now a competitor in the SD-WAN sector with its $420 million purchase of CloudGenix. Palo Alto announced the all-cash deal on Tuesday, and it is expected to close in its fiscal fourth quarter once it clears the usual regulatory hurdles.

The deal for CloudGenix is notable on several fronts. Increased security by SD-WAN vendors has been one of the major trends over the past few years, which has generated business for Palo Alto Network's firewall virtual network functions.

CloudGenix was rumored to be on the market last year. The deal with Palo Alto Networks marked what could be more consolidation among the 60-plus vendors in the marketplace.

"This is the classic convergence between SD WAN and network security," said Lee Doyle, principal analyst at Doyle Research. "This gives Palo Alto an SD-WAN feature as part of its security offering. It gives them one of the leading independent SD-WAN players. It also gives Palo Alto CloudGenix's customer base and leading edge technology to incorporate into their offer."

Palo Alto Networks will integrate CloudGenix's cloud-managed SD-WAN products with its cloud-based Prisma Access security to accelerate the on-boarding of remote branches and retail stores. Palo Alto said the combination would extend the breadth of the Prisma Access SASE platform, address network and security transformation requirements, and accelerate the shift from SD-WAN to SASE. SASE, which was coined by Gartner last year, defines a sub-trend in SD-WAN, which includes integrating SD-WAN with cloud-based security applications.

What is SD-WAN?

The term SD-WAN is an acronym that stands for Software-Defined Wide-Area Network. It is a term that relates to SDN(Software-Defined Networking) and is something that is used by thousands of companies across the country and further afield as they look to connect different parts of their business to a wireless network.
