Now, that we have set the scene about SD-WAN, let’s discuss the particular case of SD-WAN in Myanmar and why we believe this is a great technology for the country at this moment in time.
As we have discussed extensively, SD-WAN provides significant benefits to enterprises:

1.SD-WAN eases the implementation of Disaster-Recovery Plans

According to Wikipedia, “Disaster Recovery involves a set of policies, tools, and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster”. Failing to design and implement DR puts businesses at risk of data loss which can lead to economical loss or worst bankruptcy.
Which the emergence of virtualization and cloud-based solutions, replicating workloads from site to site has never been simpler.  But activating a simple replication feature is by no means enough to achieve a disaster recovery plan.
One of the most complex parts of a Disaster Recovery Plan is to design how remote users resume access to business applications through a disaster scenario. As SD-WAN is completely abstracted of the physical layer and centrally managed, it makes a great case for ensuring that all traffic is redirected to the disaster site.
SD-WAN can help to build and operate a point to multipoint network between the branches and a DR site in a few easy steps. The leading SDWAN solutions in the market are also compatible with the most popular private and public cloud providers (VMware, AWS, Azure, Google Cloud, Alibaba) which enable enterprise customers to quickly deploy a hybrid approach with a Disaster Recovery Site in the cloud.

2.SD-WAN improves reliability and performance

SD-WAN is a perfect solution to implement site redundancy. The technology is entirely agnostic of the underneath infrastructure which means that the company looking to implement SD-WAN can leverage existing connectivity no matter the medium.
Furthermore, SDWAN runs seamlessly over Fiber, xDSL, Wifi, 3G, and 4G Mobile Data, even VSAT. It lies on OSI Layer 3 and works seamlessly over any Internet and MPLS connectivity.
 By implementing SD-WAN on top of two diverse Internet connections, the enterprise can obtain high availability and improve user experience.
Furthermore, SD-WAN provides the capability to tag applications and protocols that are critical to the business (E.g., VoIP, Videoconference…) and ensure that in case of performance degradation or unavailability of one of the upstream links, these get priority over non-business-critical applications.
SD-WAN also optimizes network performance. It monitors the characteristics and real-time performance of the upstream and steers packets to achieve optimal performance.

3.SD-WAN is cost-effective

One of the sale arguments of SD-WAN is also the cost reduction on the underlying infrastructure as SD-WAN limit the enterprise investment in private lines as SD-WAN works perfectly over standard Internet services.
In Myanmar, this argument is quite relevant as MPLS connectivity is expensive, at least 10x more expensive than broadband internet access.
For those looking to cut down costs, a solution to explore could be to use home / SME broadband connectivity to protect an existing enterprise dedicated uplink with SD-WAN. The current price for a 10Mbps home broadband in Myanmar is around 25000 MMK ~ $ 19 per month which makes an easy business case for a redundant solution.
Another cost reduction opportunity is on the Internet connectivity of the main site.
For security reasons, enterprise IT administrators usually implement one or two Internet gateways for an entire organization. These gateways are usually located at the company data center or headquarter.
This to ensure that Internet traffic goes through all the Internet security policies no matter where the user is located.
As more and more applications are hosted in the public cloud such as Office365, or Salesforce, Internet traffic keeps growing for the enterprise.
Enterprises that implement a centralized firewall/gateway to access the Internet are somehow billed twice for Internet bandwidth. First, at the branch level where the Internet is the underneath technology for the point to multipoint WAN network. Second, at the HQ level when the traffic goes out to the Internet.
As SD-WAN can implement consistent security policies across the entire organization, it is absolutely possible to let the internet traffic of the branch exits directly at the branch level, therefore, reducing drastically the internet usage at the HQ level.

4.SD-WAN centralized management could be outsourced to a Managed Service Provider such as GlobalNet

As SD-WAN is centrally managed, it reduces the need for technical resources across your network. The complete network and security infrastructure can be managed from the SD-WAN orchestrator sitting in the enterprise cloud or the public cloud.
With years of experience in the IT and ISP field, GlobalNet can help enterprises in Myanmar implement SD-WAN in a managed service fashion, offloading the IT department from the day-to-day support and operation and allowing them to focus on new innovative projects and digital transformation.

5.SD-WAN is your gateway to public cloud

SD-WAN can be deployed easily in the cloud. If you take a look at the AWS marketplace, for instance, you will find SD-WAN products readily available for deployment. Among them, the top brands for SD-WAN:

1. VMware SD-WAN by VeloCloud Virtual Edge
2. Cisco Cloud Services Router (CSR) for SD-WAN
3. Citrix SD-WAN Standard Edition
4. CloudGenix ION SD-WAN Virtual Appliance
5. Riverbed SteelConnect Gateway (SD-WAN)
6. Silver Peak Unity EdgeConnect for AWS
7. Fortinet FortiGate Next-Generation Firewall
More and more companies these days are adopting a hybrid cloud strategy.  A hybrid cloud is a mixture of a private cloud (usually the enterprise data center) combined with the use of public cloud services like AWS or Azure. The objective is to combine services and solutions from a selection of cloud providers to create a unified and consistent computing environment.

SD-WAN fulfills this need for consistency by implementing a standard set of network and security policies across the board.
