Network interconnection with Google Cloud Platform (GCP)

This time, we will use the example of network interconnection between Colt's "Dedicated Interconnect" and "Google Cloud Platform (GCP)"

between an on-premises environment and a public cloud environment
, or when sharing network bandwidth among multiple departments,
deploying and building a dedicated line is suitable to avoid network latency.

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

Two patterns of network interconnection

There are two connection methods you can choose from to interconnect public clouds and networks: "Dedicated Interconnect" and "Partner Interconnect"

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

■ Shared type (Partner Interconnect)
- Single BGP peering / VLAN-based
- Shared DCA-NNI
- Enables connection to dedicated lines at minimal cost

Network interconnection with Google Cloud Platform (GCP)

In the GCP console below, select "Dedicated Interconnect."

*Please note that when connecting to the network, you will be charged monthly by two companies (two services): "Colt's line charges" and "GCP's port/data usage charges."

To establish network interconnection with Colt,
in Japan, you will need to select one of the following data centers: "Equinix TY2" or "ComSpace 1".

summary

Colt's network services primarily consist of Ethernet and dedicated lines,
which may give the impression of higher costs compared to inexpensive best-effort network lines. However, it
is an ideal service for businesses with the following requirements:

■ With the increasing use of cloud services, communication latency on best-effort lines has become a concern.
■ We want to centrally manage and integrate network connections between domestic and overseas locations using a single telecommunications carrier.
■ We want to run systems that require mission-critical workloads.
