Big Cloud Fabric enables virtual private cloud (VPC) based logical networking, delivering network automation and visibility to both on-premises enterprise clouds and multiple public clouds. With consistent networking principles and governance policies, IT organizations can finally bring the hybrid cloud vision into reality.

IT organizations face great challenges with siloed approaches to hybrid cloud: As long as on-premises and public cloud environments have completely different styles of networking and governance processes, IT needs two different teams to manage hybrid cloud networking. With silos, where to place applications depends on infrastructure and governance constraints, which leads to greater complexity, higher cost, and higher service enablement latency.

Big Cloud Fabric™ is the first of its kind to adopt public cloud networking with IT governance to streamline hybrid cloud deployments. This approach is customer driven, as a majority of enterprises will deploy hybrid cloud within the next five years if current trends continue. In this environment, no matter where applications reside or how mobile they become, enterprises need common networking fabrics. To avoid bifurcation—and yet another vendor lock-in by cloud providers—the Big Cloud Fabric approach unifies network configurations, visibility, automation, and Day-2 operations management.

BCF Overview

Core to BCF is the definition of logical networks which are defined within the SDN controller abstractions. Given the popularity and benefits of VPCs, BCF embraces VPC as the universal construct across both on-premises data centers and multiple public cloud environments. By enabling VPCs to run anywhere with governance, this approach eliminates network dependencies, giving IT organizations more choices for where to place applications.

Offering the same constructs in any BCF location greatly simplifies Day 0 through Day 2 operations management, thanks to common APIs for network automation, inventory, and troubleshooting. With a single button, network or cloud admins can pull up rich data on every object deployed and running within the fabric.

BCF comes in two form factors: Enterprise Cloud and Public Cloud

Big Cloud Fabric – Enterprise Cloud (BCF-EC) is an SDN-based physical switching fabric that leverages open networking switches. Not only does BCF-EC offer VPC consistency with the public cloud, it supports many Day-2 operations management tasks of deploying, configuring, and maintaining the data center infrastructure with zero-touch provisioning, remediation, and integrated alerting. The operations controls significantly alter the calculus of comparing total cost of ownership for public and enterprise clouds, whether by capital or operational expenditure.

Big Cloud Fabric – Public Cloud (BCF-PC), is virtual, for deployment in multiple public clouds such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Independent of the public cloud persona, BCF-PC offers complete management and visibility of VPCs. This approach gives the IT team a means for discovery, visibility, and compliance checking of all VPCs configured within the user account. BCF-PC also enables IT to configure VPCs for new applications from within BCF, and extend security policies to ensure consistency in any public cloud. BCF-PC supports the emerging hub-and-spoke VPC model, where application VPCs flow through transit VPC for cross-VPC, on-premises, or Internet-facing communication.

VPCs serve as the cloud-first network identifier. While networking know-how remains a prerequisite for configuring VPCs, its universal construct that has become user friendly within application communities, that general acceptance cuts through layers of bureaucracy, complexity, and delays in getting applications up and running. Big Cloud Fabric extends the same advantages on premises, while adding a layer of governance and external control to VPCs configured within public clouds. Customers benefit on both ends.

BCF leverages the VPC advantages

The Big Cloud Fabric offerings incorporate and extend the advantages of VPC. The customer benefits derive from four key principles.

  • VPC consistency Consistent network management and operations is the number one requirement for IT organizations embarking on a hybrid cloud path. With VPC as a normalized unit of networking, BCF enables a common operations toolchain for applications deployed either on-premises in the enterprise cloud or in any public cloud. IT admin can easily generate compliance reports. Network teams have a well designed troubleshooting workflow. With VPC as the underlying unit of networking, cloud lock-in becomes a thing of the past. IT can now govern consistently.
  • VPC automation BCF-EC is integrated with the more popular enterprise orchestrators such as VMware, Nutanix, HCI, containers, and OpenStack. BCF-PC integrates with multiple public clouds, including AWS, Azure, and GCP. With VPC automation, the network becomes invisible — no longer a barrier to application deployment, whether on premises or in any public cloud.
  • VPC visibility Both BCF-EC and BCF-PC offer rich flow-level visibility and infrastructure monitoring, including the workload attributes within VPCs.
  • Single pane of glass across multiple sites and multiple clouds Core to any hybrid cloud journey is the need to manage multiple networking fabrics. Integration with Multi-Cloud Director provides this capability for multiple instances of BCF-EC and BCF-PC. Because all BCF deployments have the same database object definitions, Multi-Cloud Director easily centralizes and manages complex deployments.

Imagine a network that allows the application community to autoselect their networks in a language they already understand: VPCs.

Imagine a network that eliminates network dependency when making decisions about where to host applications.

Imagine a network you can deploy the same way whether it is an on-prem physical network or within a provider cloud where the physical network is abstracted.

Imagine a network that autoconfigures whenever a new switch element is added or removed, when a new host is added or removed, and when a new VM/container is added or removed.

Imagine a network that pulls up and compares inventory data across multiple sites for monthly compliance checking.

Imagine fabric upgrades within minutes—without paying routing convergence tax.

Imagine pinpointing a network issue in a single click rather than hunting from box to box or across many different tools.

Imagine a network that provides freedom from vendors. Where you can select hardware from various switch vendors. Where you can choose any public cloud vendor and be free to switch at any time in future.

Extending the public cloud networking concept of VPC everywhere offers pervasive network automation and visibility. BCF truly delivers the benefits of the hybrid cloud era: consistent policy, common operational toolchain, rapid service enablement, and transparent application deployment.
