What is Cloud Infrastructures?
Cloud infrastructure refers to the hardware and software components that support the requirements of a cloud computing model. These components include:
- Virtualization software
- Management tools
Cloud infrastructure also includes an abstraction layer that virtualizes and presents resources and services to users through application program interfaces, as well as API-enabled command-line or graphical interfaces.
With cloud computing, these virtualized resources are hosted by a service provider or IT department, and are delivered to users over a network or through the internet. These resources include:
- Network switches
- Load balancers
Cloud infrastructure components
Cloud computing is the on-demand availability of computer system resources without the need for direct active management by the user. These system resources primarily include data storage and computing power.
Cloud storage is the ability to store files / data in a facility other than your own on premise systems. It gives a business the ability again to backup or just expand their storage systems without incurring the whole cost of maintaining the new systems. Cloud storage also gives the business the ability to access their data anywhere from the internet regardless of where they are or device they are using. As with all cloud based systems you can add resources when needed, which is always a plus in a world that is creating more & more files from someone movie collection to a small business that uses a podcast to get their message out to employees or customers.
Cloud Hosting (Shared Resourses)
Cloud Hosting or web hosting as some may call it is a bit different than
just normal shared hosting. You have 3 different levels of web hosting &
each one of them has their plus’s then minus. Shared hosting is on the
bottom of the chain & cloud hosting is at the top of the chain.
VPS stands for Virtual Private Server. A VPS is a space on a server that has the characteristics of an entire server itself. A virtual server hosting has its own Operating System (OS), applications, resources, and configurations. All of this is contained within a single powerful server. Each server can have multiple VPS accounts on it.
Cloud PBX (Cloud-based Private Branch Exchange) is a virtual PBX system rooted on the internet, which automatically answers all calls and routes them to the right department or user extension. Traditionally, PBX systems are housed on-premises. These machines are big and need their own storage room. They also require significant capital investment, making them out of reach for smaller businesses.
