Dedicated Cloud Access

Connect the office or data centre to your cloud over a private path.

Dedicated Cloud Access (DCA) connects supported providers such as AWS, Azure and Google Cloud. It suits private workloads; start with the origin, region and routes required.

Validate the cloud provider (CSP), region, on-ramp, layer, routing and capacity; other traffic may still use the Internet.

How it works

Connect your locations to the cloud you use, with clear boundaries.

Office or data centre
Colt connection
CSP private network
Cloud on-ramp

Three domains, one journey

The office or data centre reaches the cloud provider’s on-ramp through Colt. Associate the connection with the correct cloud network and agree ownership of routing, authorisation and security.

Colt lists connectivity agreements with AWS, Microsoft Azure, Google Cloud, Oracle OCI, IBM Cloud and OVHcloud. Validate region, on-ramp and service variant for the project.

The circuit can be healthy while the application is not

Check connection state, routing sessions, prefixes, MTU and capacity limits. Then distinguish cloud networking, DNS, permissions and the performance of the service used by the application.

Measuring only the site port misses part of the journey. Agree evidence and contacts for both domains so an incident does not become a dispute over ownership.

Two paths, including the cloud side

Resisting an outage requires connections and on-ramps suitable for the CSP, with recovery routing. Two circuits ending at one location can share a failure domain.

Internet backup needs an explicit alternative architecture; it does not appear automatically. Test path loss, remaining capacity and application reachability before migration.

Connect to your cloud

From an office or data centre, DCA uses a private path, not the public Internet. We define access, cloud entry point (on-ramp), region and routes. Providers with direct agreements listed by Colt:

  • AWS
  • Microsoft Azure
  • Google Cloud
  • Oracle OCI
  • IBM Cloud
  • OVHcloud

Other options listed by Colt: Salesforce, SAP, Alibaba Cloud.

DCA provides connectivity. Compute, storage and hosting are not included; your CSP bills separately for its services. We validate region, on-ramp and service variant for your project.

Illustrative case: from situation to decision

Situation
An office uses a private business application in the cloud alongside Internet browsing.
Option
Use DCA for the private flow and retain Internet access for public services.
Check
Test routes in both directions, provider permissions and separation of the two flows.

DCA is connectivity; compute, storage and cloud-provider services are contracted separately.

Decisions for your project

Provider and region
CSP, on-ramp service, account, region and source locations.
Routing and permissions
Prefixes, BGP where applicable, MTU, authorisations and non-overlapping networks.
Continuity and cost
Diversity through to the CSP, standby capacity and each party’s charges.

From design to operation

Inventory flows, validate region and access, coordinate with the cloud administrator and test applications before cutover.
