Enterprise-Class Traffic Engineering– Static Architecture Becomes Dynamic and Resilient Business leaders have zero-tolerance for business-critical application downtime and network connectivity is like electricity, if connectivity is down, the application is down. Native cloud networking solutions are no panacea. Enterprises who explore using native cloud constructs, such as AWS Transit Gateway or Azure vWAN, soon discover they cannot leverage the dynamic resiliency and traffic engineering they have relied on in data center and enterprise WAN networking in the past. For example, neither AWS or Azure networking supports dynamic alternative path routing, allowing the primary route to be the lower latency, hyperscaler inter-region connection, but dynamically failing over to the enterprise private interconnection and private WAN connection if the cloud provider link is not available. Native cloud networking constructs only allow simple, static routes that fall short of delivering a dynamic, resilient network architecture that enterprise business-critical cloud infrastructure demands. ENTERPRISE BENEFITS WITH A CLOUD NETWORK BACKBONE FROM AVIATRIX 1. Reduced Latency – Inter-Region Traffic Stays on Hyperscaler Infrastructure As the center of gravity for enterprise IT moved from data center to cloud, enterprise network architecture evolved. Many enterprises defaulted to a "connect to the cloud" architecture that simply connected their data center networks to the cloud with private interconnect services such as AWS Direct Connect, Azure ExpressRoute and Google Cloud Interconnect. As more workloads and business-critical applications moved to the cloud, cloud environments grew from single region to multi-regions and network teams routed traffic through data centers and over private WAN networks to gain visibility and troubleshooting capabilities required to support business critical applications. This architecture resulted in additional latency for inter-region traffic. Traffic from one cloud provider region was routed out of the cloud, to the enterprise data center, across the enterprise WAN backbone to another data center or colocation infrastructure and finally out to another cloud provider region. Aviatrix Cloud Network Backbone Solution: While it is possible to connect using native cloud networking constructs to build an inter-region transit network, enterprises lose the visibility and control required to support business critical applications in the cloud, increasing meantime to resolution and downtime. Aviatrix keeps inter-region cloud network traffic on the hyperscaler's infrastructure, leveraging the high-speed underlay. This reduces the number of routing hops and therefore the latency. Utilizing the Aviatrix solution delivers several additional benefits including dynamic routing and traffic engineering, enterprise-grade operational visibility and troubleshooting capabilities, high-performance encryption and cloud infrastructure cost optimization.
