Network interconnection with Google Cloud Platform (GCP)

Colt's "Dedicated Interconnect" and
we will use the example of network interconnection between

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

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

■ 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

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.
