CDN’s Infrastructure as a Service packages allow the flexibility of keeping your data centre outsourced and up to date with all the latest hardware without the expense of owning your own equipment and being responsible for housing, running and the maintenance of it.
The IaaS is the Physical composition of the Data Centre structure. It comprises of the Hardware footprint which acts as the foundation to house the PaaS (Platform) & SaaS (Software or Applications), and generally includes the following components:
- The Physical servers (Hardware) in a Rack formation with multiple CPU, disks, ram, etc
- The storage or RAID that are attached to the servers and provides TeraBytes of disk space
- Networks – Fibre & UTP to connect the servers, Storage devices and the outside world (Users)
- Virtual Machines (VM) – Virtual replication of unit servers created on top of the Physical servers (Hardware). A customer can purchase their own VM. Typically Hyper-V & VMware are used.
- Clusters of servers – Joining physical servers in parallel for redundancy purposes with auto or manual fail-over.
- Load Balancing – Joining physical servers in parallel for performance increase to produce a scalable “Web Farm” and includes redundancy.
- Firewalls – Routers and switch hubs to segregate the networks and control user access. Creates VLAN & VDOM’s with WAN access via VPN, DMZ, IPSEC, etc.
- 19” Racks, Rack accessories, UPS, A/C, power, cabling, etc are included with CDN’s IaaS pricing.
The IaaS service is sold with an upfront fee and monthly or annual payments that includes ongoing maintenance, expansion and 24/7 support.
The PaaS is required and can be provided by the customer or by the Data Centre vendor. CDN provides all the Microsoft range of PaaS products.
If a customer purchases the SaaS products like CloudVue or CRD, then the PaaS & IaaS are included in the costs.
