A TV channel is developing a Video On Demand application. The IaaS resources used for this application are hosted in AWS while the original database for video streaming is currently hosted in the customer’s datacenter. This origin server is connected to a Content Delivery Network (CDN) to deliver media streams to growing audiences with the needed quality.
The customer uses the InterCloud connectivity to access its five Video On Demand application environments in AWS: development, test, pre-production, production and big data.
To ensure full isolation of the data flows to and from each application environment, the media chose to separate the 5 environments in 5 VPCs while using InterCloud’s private connectivity to isolate each data flow through AWS Direct Connect up to the customer on premises. This means that the data flow for each individual environment is fully isolated, providing much-needed traffic segmentation according to each environment’s criticality and performance requirements. Traffic segmentation allows granular network visibility for better monitoring, control and faster troubleshooting.
There was growing concern about soaring connectivity needs between the on-premise database (origin server) and the CDN that grew from 2 Gb to 5 Gb in just 6 months. Although it makes sense to move this data lake to the Cloud to rationalize connectivity costs and guarantee latency reduction as well as the stability of media streams, the customer’s challenge is to temporarily scale up the bandwidth during the migration and scale it down once completed. Leveraging InterCloud’s flexible bandwidth called Capacity, the customer can allocate and reallocate it at will.
Securing both to accesses for the VOD application resources and the origin server is absolutely critical to our customer. To do so, the media chose Fortinet’s firewall to secure application flows between AWS infrastructure and its premises. This Fortinet Virtual Network Function (VNF) is virtualized and hosted in the InterCloud platform to centralize and optimize all cloud connectivity towards AWS. The advantage of the flexibility brought by this VNF is all the more relevant when this application has a multi-cloud architecture. In this example, the media plans to replicate its AWS environment in two other Cloud Providers in different regions. InterCloud’s VNF service insertion saves the customer the costs and complexity of replicating the Fortinet infrastructure and service in different CSPs or world regions.
