Zorluk: KolayDesigning Network Architecture and Hybrid Connectivity

A financial services organization needs to establish private, SLA-backed hybrid connectivity between its on-premises data center and a Google Cloud Virtual Private Cloud (VPC). The solution must support a throughput requirement of 1 Gbps without traversing the public internet. The organization does not have a presence in a Google colocation facility. Which Google Cloud connectivity solution should the cloud architect choose?

  1. Partner InterconnectCevap
  2. B
    HA VPN
  3. C
    Dedicated Interconnect
  4. D
    VPC Network Peering connected to a third-party partner VPC

Cevap

Partner Interconnect is the appropriate choice because it delivers private, SLA-backed connectivity to Google Cloud through a supported service provider without requiring direct physical presence in a Google colocation facility.
Partner Interconnect connects on-premises networks to Google Cloud VPC through a supported service provider. It satisfies requirements for private transport (bypassing the public internet), provides SLA guarantees, supports 1 Gbps capacities, and does not require the customer to co-locate in a Google edge facility.

Adım Adım Çözüm

1
Evaluate internet path requirements
Disqualify HA VPN because the requirement explicitly forbids traffic traversing the public internet.
HA VPN relies on public IP routing over the internet for IPsec tunnel establishment.
2
Evaluate co-location constraints
Disqualify Dedicated Interconnect.
Dedicated Interconnect mandates a direct cross-connect at a Google colocation facility.
3
Evaluate network topology and transit rules
Disqualify VPC Network Peering as a hybrid connectivity mechanism.
VPC Peering is non-transitive and connects VPC networks internally, not on-premises sites.
4
Select supported service provider hybrid option
Partner Interconnect fulfills all throughput, private routing, SLA, and co-location constraints.
Partner Interconnect allows connection through a service provider at bandwidths starting from 50 Mbps up to 10 Gbps.
