This time, we will use Colt's "Dedicated Interconnect" and
network interconnection with "Google Cloud Platform (GCP)" as examples.

between on-premise environments and public cloud environments
, or when sharing network bandwidth among multiple departments,
it is best to introduce and build a dedicated line to avoid network delays.

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

Two patterns of network interconnection

There are two connection methods to interconnect public clouds and networks:
"Dedicated Interconnect" and "Shared Interconnect."

■ Dedicated type (Dedicated Interconnect)
・Dedicated 10G port type for Google Cloud Platform (GCP) only
・Provides cross-connect with Colt's dedicated port
・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
- Connection to a dedicated line is possible at the lowest cost

summary

Colt's network lines mainly consist of Ethernet and dedicated line services, which
may seem to increase costs compared to cheaper best-effort network lines, but
it is an ideal service for businesses that have the following requirements:

■ With the increasing use of cloud computing, communication delays are becoming a concern with best-effort lines.
■ We want to centrally manage and integrate network connections between domestic and overseas bases using a single communications carrier.
■ We want to operate systems that require mission-critical workloads.
