WCI management hired you as a Security Architect for their Cloud strategy and requested you to evolve a Hybrid Cloud infrastructure solution including a private connectivity to Public Cloud. WCI tasked you to connect their existing datacenter infrastructure services with a Public Cloud service provider (CSP) so that they can integrate their on-premises VLAN hosted databases with Public Cloud hosted Web applications running in a VPC. WCI wants to assure direct network connectivity from Public Cloud hosted VPC to its VLAN segmented internal networks specific to departments such as Engineering, Development, Sales, Support and Finance so that they are fully isolated in terms of compute and network services.

The CEO of WCI requested you to recommend an industry-standard protocol for establishing private connection for exchanging routes between their on-premises datacenter and their VPC.

1. Identify a protocol solution that enables private connectivity between their on-premises location and public cloud hosted VPC? Briefly describe how the security isolation characteristics can be assured between the VLAN in a Datacenter and VPC in Public Cloud.
2. Draw a high-level topology diagram of the proposed Hybrid Cloud Architecture which illustrates the private connectivity between their on-premises data centers running 5 internal VLANs - A (Engineering), B (Sales), C (Support), D (Finance) and E (Development) to 5 VPCs residing in Public Cloud. WCI uses AT&T as their Internet Services Provider (ISP) and they will act as the Intermediary between the Public Cloud Provider and WCI datacenters. The CEO recommends each VLAN must use and connected to a dedicated VPC for each department. The CEO also want you to verbalize and document the security characteristics of the applied isolation solution.
   • Show the diagram clearly labeling all the building blocks intended for connecting VLANs in WCI datacenters to the VPCs residing in a Public Cloud.
     • Use Microsoft PowerPoint or your choice of diagramming tool for creating the topology diagram.
