Network interconnection with Google Cloud Platform (GCP)


, we will take as an example the network interconnection between Colt's Dedicated Interconnect and

between an on-premises environment and a public cloud environment
, or when sharing network bandwidth among multiple departments,
it is appropriate to introduce and construct a dedicated line to avoid network delays.

Colt is also connected to most GCP POP regions.
(Tokyo, Hong Kong, Singapore, London, Paris, Frankfurt, Amsterdam)

Two patterns of network interconnection


You can choose from two connection methods to interconnect the public cloud and network:
"Dedicated Interconnect" and "Shared Interconnect."

■ Dedicated Interconnect
- Dedicated 10G port type only for Google Cloud Platform (GCP)
- Provides cross-connect with Colt dedicated port
- Colt bandwidth: 1-2-5-10Gbps
- Same Multiple BGP sessions, VLANs, and multiple VPCs on a port

■ Shared type (Partner Interconnect)
/Single BGP peering/VLAN based
/Shared DCA-NNI
/Connection with dedicated line possible at minimum cost

Network interconnection with Google Cloud Platform (GCP)

In the GCP console below, select "Dedicated interconnect" this time.

*When connecting to the network,

two companies (two charges) will be collected each month: ``line fee from Colt'' and ``port/data usage fee from GCP.''

To perform network interconnection with Colt,
if you are in Japan, select one of the following "Equinix TY2" or "ComSpace 1" data centers.

summary

Since Colt's network line mainly provides Ethernet/dedicated line services,
it seems that the cost will be higher than a cheap best-effort type network line, but it
is suitable for corporations with the following requirements. is the best service.

■ With the increasing use of the cloud, communication delays with best-effort lines have become a concern.
■ You want to centrally manage and integrate network connections between domestic and overseas locations using one telecommunications carrier.
■ You want to run systems that require mission-critical workloads.
