Scalable computing that flexes with the speed of your business

Business change is hard to predict, particularly in a challenging economy. Rigidly structured IT infrastructure cannot provide the flexibility that such business change demands.

Is your business growing at an unpredictable rate? Do you experience seasonal peaks in IT demand? Are you considering a merger or acquisition? Do you need a local service?

With IaaS (Infrastructure as a Service) from Colt you can scale your IT infrastructure in line with your business. Upgrade/ downgrade on the go via Colt’s ISO27001 data centres underpinned by our enterprise grade data network.

Colt owns and manages over 20 data centres across Europe – where we were the first vCloud Virtual Datacentre Service Provider.  Our local presence and extensive experience means that your services, data and applications stay within your country, and are in line with the most rigorous local regulations.

Which IaaS is right for you?

Colt’s IaaS (Infrastructure-as-a-Service) services combine IT scalability with enterprise quality and commercial flexibility. Services can be configured and consumed from European data centres via different models tailored to your needs:

  • If you need to spin up IT resources for immediate use and with minimal technical expertise, you can opt for our On-Demand IaaS services. These will allow you to scale resources up and down as needed, keep track of your resources and pay per server, per hour.
  • If you need direct access to a pool of IT resources in order to build a self-managed infrastructure, you can opt for our vCloud Virtual Data Centre services. These will allow you to easily leverage internal and external IT resources and build hybrid cloud environments. You will have more visibility and control over the end-to-end infrastructure configuration.

We understand each business is different and we will help you decide on which IaaS service and management options are best fit for you – self-service, partially or fully managed.

When you require agility, flexibility, and an end-to-end range of infrastructure offerings, Colt delivers with quality, integrity and reliability.
