Summary of Hybrid Cloud Architecture

Hybrid cloud architecture is the combination of public and private clouds by a wide area network or broadband connection, through which applications and data can be shared and which can be managed as a single IT architecture.

(a) Connect over the Internet (b) Connect over VPN (c) Connect over Direct Connect

Hybrid Cloud Architecture Details

#UseCase It is well suited to fluctuations in demand for computing resources since it enables businesses to scale from on-premises to public cloud-based to meet increased demand, and scale back from the public cloud to on-premises (private cloud) only once demand recedes.

  • Customer Gateway on the on-prem data center and a virtual private gateway on AWS is required

Network to AWS VPC

[[VPC]] connectivity from other clouds or on-prem requires various architectural considerations. AWS Whitepaper PDF

Site-to-Site VPN

Customer Gateway Device (On-premise)

  • Install [[CGW | Customer Gateway]]
  • Decide on IP Address
    • Public Internet-routable
    • [[NAT]]-T (NAT Traversal) public IP fronting the [[CGW]]
  • Routing
    • Route Table propagation in each route table within a [[subnet]] must be enabled.
    • Ping requires [[ICMP]] protocol in Security Group to be enabled. [[VGW | Virtual Private Gateway]]

Use Cases for Hybrid

  • Cloud Bursting
    • Storage and compute bursting in the cloud
  • Global Reach
    • Use S3, CloudFront and other services on the edge and other regions.

VMWare Cloud expanded to AWS

A company that is already running VMWare on premise can expand into AWS. ![[VMWare on AWS Cloud Architecture.png]] Fig. VMWare Cloud on AWS
