TCTS Cloud Networking as a Service for SD-WAN

 

Software Defined WAN – SDWAN
As SD-WAN technologies transforms the wide area networks of most businesses, IDC predicts the Global SD-WAN Infrastructure Market to be $5.25B by 2023 with a CAGR of 30.8%. The key business drivers for enterprises are easier management of WAN connectivity, improved user experience, application performance guarantees, better support for cloud-based applications and hybrid multi-cloud usage. However, SD-WAN started within the enterprise as a Do-It-Yourself (DIY) project but has recently evolved into managed services by most operators worldwide. IDC predictions of the US SD-WAN managed services market is expected to grow at a CAGR of 74% to $4.5B by 2023. As this paradigm shift to SD-WAN continues to grow, TCTS is happy to provide operators worldwide a fully managed white-label service that integrates SD-WAN and clouds, which includes a full range of professional services from planning, deploying and operating SD-WAN at the customer sites with cloud integration.

TCTS SD-WAN for Azure Virtual WAN
Tata Communications Transformation Services (TCTS), partner of choice for the world’s leading Service Providers (SPs) and a wholly owned subsidiary of Tata Communications, together with Microsoft Azure, has launched a fully managed SD-WAN offering for Azure Virtual WAN. Built to help Service Providers create solutions to further enable enterprises with seamless migration to the Azure cloud, the TCTS SD-WAN offering will enable service providers to increase their revenue in IT migration to public clouds. In partnership with Azure and strategic vendors, TCTS has augmented Azure’s current Virtual WAN offering in which application polices can be centrally configured using Fortinet SD-WAN technologies to deliver both performance guarantees and security protection. This offering enables inter-branch connectivity for customers using the Microsoft backbone, and enables them for site-to-site, site-to-cloud and hybrid MPLS/Internet support while utilizing Azure Virtual WAN services with the addition of application performance steering with SLAs utilizing SD-WAN technologies in partnership with strategic SD-WAN vendors.

TCTS’s SD-WAN offering enables enterprises at any given site to use a hybrid deployment of MPLS and Internet to steer the traffic between mission critical traffic (MPLS and Carrier Ethernet) and non-mission critical traffic (Internet), which further connects directly to Azure’s clouds via Express Route. This connection can be established leveraging TCTS’ award winning platform, ‘Virtual Cloud exchange’ for building within native service provider environments or white labeled edge solution offerings within their data centers globally. TCTS’s SD-WAN solution utilizes modernized Software Defined Network (SDN) and Network Function Virtualization (NFV) principles that enables Microsoft Azure enterprise customers to choose either a standard offering, that needs no further SD-WAN Virtual Network Function (VNF) in Azure’s cloud, or a more advanced option that places a SD-WAN VNF in Azure’s cloud to deliver SD-WAN application traffic steering and security protection bi-directionally.

TCTS SD-WAN and Azure Virtual WAN Standard Offering
In the standard Azure SD-WAN Virtual WAN offering, thousands of applications can be selected and assigned SLA performance objectives. The SD-WAN edge at any given site will then traffic steer accordingly to the SLA performance objective provisioned by the enterprise subscriber. It should be noted that in the standard model, traffic steering is only unidirectional from any given site towards the Azure cloud. Any returning traffic will not be traffic steered by the cloud, however the path back to any site should follow the originating path so that path unification is maintained. The key value proposition of SD-WAN being built on top of Azure Virtual WAN is the following:

Value Proposition:

  • Site-to-site, site-to-cloud and device-to-cloud utilizes Azure Virtual WAN including Azure’s global backbone
  • Express Route is fully automated using orchestration, SDN and NFV via TCTS’s patented Virtual Cloud Exchange (VCX) solution offering. Since Express Route requires BGP and possible NATing, all of the routing functions are automated using SDN separation of the control and forwarding planes. A full NFV implementation supporting both BGP control and IP forwarding VNFs are utilized. Both IPv4 and IPv6 are supported.
  • Hybrid MPLS/Internet and all Internet local loops are supported. Smaller sites can use an all Internet approach while larger site can use the hybrid approach.
  • Hybrid Virtual WAN and SD-WAN polices are combined by the SD-WAN edge appliance.
  • No SD-WAN virtual appliances or any additional non-Azure virtual functions are required in the Azure cloud. This makes deployment of SD-WAN for Azure Virtual WAN vastly simple. However, traffic steering is unidirectional only from the site to the cloud.
  • Security functions can we added to any given site SD-WAN implementation and Azure native security function can be invoked in the Azure cloud
  • Each enterprise customer gets their own Azure Virtual WAN hub and Express Route gateway in their own VNET. Any Azure region can be configured using this method and then inter-region routing can be configured utilizing native Azure routing and gateway functions

TCTS SD-WAN and Azure Virtual WAN Advanced Offering
In the advanced version, all the standard features and value proposition are supported with the addition of the following:
Value Proposition:

  • SD-WAN traffic steering is now bi-directional. SD-WAN traffic steering will occur in both directions site-to-cloud and cloud-to-site.
  • A SD-WAN virtual appliance needs to be installed and configured in the Azure cloud VNET that belongs to the given enterprise subscriber. This adds additional complexity but delivers bi-directional SD-WAN functionality
  • Security can be invoked and configured in both the site and Azure cloud using TCTS’s SD-WAN partner solutions. Security solutions available for the advanced version allows security functions natively within the SD-WAN offering such as (native SD-WAN security functionality depends on the SD-WAN vendor chosen):
    • Intrusion Prevention - controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet
    • Next Gen Firewall - monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet
