As you’ve probably heard, Software-Defined WAN (SD-WAN) is one of the trendy topics of technology at the moment , however, you may not understand why it is so popular nowadays. With this blog post, I hope to clarify this.
Before we start, I would like to show you a few important points about Cloud services in general:
· More and more services are being migrated to Cloud services by companies.
· Nowadays many applications do almost 90% of processing on the Cloud.
· Almost 100% of companies think that application must be virtualized.
· Open networking is becoming more and more powerful.
Challenges of the old WAN model:
· High prices for dedicated/MPLS links
· Technical team on site
· Difficult to manage many remote sites
· Slow to deploy new services/features
· Links are not efficient for today’s apps
SD-WAN offers significant value to businesses because of its remote and/or branch offices that help these locations achieve agility and efficiency. It also helps you save money. Doesn't that sound good to you?
SD-WAN was created to deliver WAN services to your remote/branch sites in order to remove the network layer from your nightmares. With virtualization, it can enable your IT team to manage thousands of remote sites with templates, simplifying your day-to-day operations and helping your deployment team become more efficient.
Benefits of SD-WAN
· Easy to manage
· Low cost
· Zero-touch Provision
Decentralizing your branch/remote offices will help your company follow the trends of this new network generation. The user and services patterns have been changing and now is the moment we adapt ourselves to it. You don’t need to wait for a month or so to have your MPLS link working properly and pay a lot of money for it.
With SD-WAN we can have the same level of security, or better, using any internet connectivity (Cable, DSL, Fiber, 4G) that could be deployed in just a few days to accelerate your branch opening. Also, you will improve your connection to a higher level using a fast access to your cloud services.
SD-WAN would not be nearly as popular if it were hard to manage. Fortunately, it is really easy to manage and deploy new sites, helping your IT team become more efficient and focused on what really matters instead of copying and pasting CLI commands.
SD-WAN gives organizations the ability to automate the boring work with some tools to deliver fast changes, implementations, and new features to the remote sites using APIs.
Scalable and Secure Network
Using standard encryptions to provide secure connectivity between your cloud network, SD-WAN can provide a secure connection using any type of transport. Before the new device can be part of your topology, it must be authorized and allowed from the HQ to become functional.
SD-WAN helps your network become more scalable by setting up new tenants, templates, policies and traffic priorities you can securely deliver your new node in just a few clicks.
Additionally, businesses realize OPEX improvements by switching expensive MPLS services with more flexible and economical broadband connections that increase your bandwidth speed.
SD-WAN can bring you thousands of improvements in your network and infrastructure. Learn more about how powerful SD-WAN is and how you can apply these advantages to your company in INE’s SD-WAN Overview Course.
