What is Cloud Computing?
Is best described as Spreading your infrastructure needs and requirements across traditional technologies and hardware using virtualisation technologies to provide a higher level of redundancy and availability than was previously achievable at a vastly reduced price.
What is Infrastructure as a service (IaaS)?
Companies no longer rely on hardware vendors for their hardware needs. By outsourcing to a IaaS provider they can easily scale up and down their hardware requirements, without incurring the expense of buying or managing their own hardware.
What is Cloud Storage?
Is the term used when you store your companies data or personal data across the internet onto a cloud infrastructure. As your data is stored across multiple SAN storage devices and not in a single physical location this is referred to as cloud storage.
What are Application Stacks?
Application stacks are a pre-bundled selection of software which allow users to quickly deploy or configure a server by installing all the necessary software or operating system via a one-click install.
What is SAN Storage?
Storage Area Network devices are the large highly redundant and highly reliable servers that sit at the back end of all cloud computing infrastructures and provide the large amount of storage space needed in a typical cloud computing set up
What is a Node?
Used when referring to a physical server within a cloud infrastructure. A node does not contain any customer data and is only utilised for its CPU and RAM
What is Self healing architecture ?
When a node or SAN storage array fails there are additional nodes and SANs which quickly and automatically take the load ensuring continued, uninterrupted service.
What is Failover?
It means that when a node or server fails there is another one in place to immediately take the load and continue serving your webpages or application without interruption.
What is Multi-homed?
Is a process used to increase the reliability and redundancy of the network connection to the hardware, as it removes any single point of failure by bringing multiple internet connections into the platform.
What is Software as a Service (SaaS)?
This is where companies are using software that is not installed on their actual PC , but rather connecting over the internet to access the likes of google docs, email, company intranets and communication tools such as VOIP and messenger services, these are hosted by third partner providers and companies pay for access to the online tools as they need them.
What is Virtualization?
Is taken traditional hardware technology and better utilizing it to get maximum use of it and reduce the costs of deploying additional servers/ this is done by software providing a complete simulation of the underlying hardware, and allowing you to deploy multiple virtual server on a single physical hardware server
What is Os Virtualization?
Is where the virtualization technology sits on the operating system level of the server and allows for multiple isolated user-space instances.The restriction on this type of virtualization is that the multiple virtual machines all have to run on the same operating machine as the overall physical machine.
What is Para-Virtualization?
Allows the virtualization software to sit on the actual hardware level of the server , giving a far greater level of control to each of the virtual machine , users can modify their virtual servers down to a kernel level and install whatever operating system they like, this is what dediserve uses.
What is Virtual KVM Acces?
Is the level of access you receive to your para virtualized virtual server, allowing for you to perform functions such as hard reboots as well as complete power downs
