The IT infrastructure nowadays has become too complex and costly to manage without specialised professional assistance. Study shows that 70% of IT investments in most companies is billed to maintenance, leaving just about 30% for innovation and other strategic projects. To respond aptly to client's demands whilst reducing management costs, IT needs a better approach. This is where cloud computing comes into focus.

Cloud computing is an internet-based computing paradigm which allows access to dynamically scalable and virtualised resources that are typically owned and operated by a third-party provider on a consolidated basis in one or more data centre locations. It represents a significant leap from the traditional hard-wired proprietary connections among software components and their consumers, to a virtual compute platform that lets you access lightweight server, software, and data storage resources over the internet.

Cloud computing is characterised by a significant workload shift from local computers running all the necessary applications to a network of computers that make up the cloud hence a decreased hardware and software demands on the user's side. Using any customised application that runs in the cloud is as simple as logging in using an interface software which can be as simple as any web browser.

Efficiency and scalability are the primary benefits of the cloud platform. Once computer resources are moved into the cloud, you get reduced IT costs and complexities, and optimised workload and service delivery.

• A web-based platform allows you to store/retrieve data and access applications from anywhere,   anytime.
• It obviates the need to invest in IT personnel to maintain a full set of IT infrastructure.
• Services are typically charged by usage and can be scaled dynamically cutting down unnecessary   expenses.
• No upfront spending for physical equipments.
• Capacity can be increased or decreased on demand and applications can be added almost at a   moment's notice.

The Cloud Computing architecture can be divided into 2 parts: the front end and the back end. The front end is the side of the computer user, composed of a computer and the interface software or web browser required to access the cloud. The back end is composed of servers and vendor's data centers or co-location facilities that create the cloud of services. Both ends are connected to each other by the internet.
The entire cloud computing platform is administered by a high-end central server which monitors traffic and ensures everything runs smoothly. Data is stored in data centres where they are managed and kept in multiple copies to avoid data loss in case of a system breakdown.

Webvisions (Australia) cloud computing is characterised by a dynamic consolidation of IT capabilities (hardware, software, and services) to create a stable, scalable, and resilient web-based platform of IT services including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Webvisions (Australia) uses VMware ESX/ESXi virtualisation technology to partition a single physical server into several isolated Virtual Machines (VMs), each having its own isolated virtual hardware, operating system, network, and storage.

Each Virtual Machine is a fully customisable, creating an isolated, virtualised environment that behaves exactly like a real networked server. With full root access, you can configure your system as if you have your own dedicated physical server.

• Virtualised Hardware Hardware resources within the physical server are further distributed and   configured to each VM. Each VM is completely isolated and behaves exactly like a stand-alone   server.

• Virtualised Operating System Each VM within a physical server is capable of installing your choice   of Linux or Windows operating system individually.

• Virtualised Network Each of our VMs is setup in an isolated virtual network using VLAN. A virtual   network has similar attributes with a physical network, but it allows for end stations to be grouped   together even if they are not located on the same network switch. By using VLAN, one can control   traffic patterns and react quickly to relocations, as you will no longer require to physically relocate   devices. VLAN provides flexibility to adapt to changes in network requirements and allows for   simplified administration.

• Virtualised Storage System Each VM has an isolated virtual storage that's setup within a reliable,   high availability SAN infrastructure instead of physical hard disk. With virtualised storage system,   you can easily manage, copy, mirror, and swap data within the storage box and across the storage   area network (SAN)

Webvisions (Australia) cloud architecture provides a stable, scalable, and resilient platform of IT services to help you undertake and complete your most ambitious IT projects whilst staying away from plumbing concerns.

1. Incremental Scalability

Consumers have the ability to grow dynamically in response to increasing demands. IT departments that anticipate an enormous uptick in workload need not scramble for additional hardware and software. Storage capacity, computing power, security, and other IT functions can be increased or reduced on demand without any costly service interruptions.

2. Reduced Cost

The pay-as-you-go approach ensures no wasted resources by over-subscribing, upfront capital expenditures for hardware and software components, and implementation of services. Pay only for what you need. A Greener approach; save energy, power, and avoid EOL (End of Life) hardware.

3. Reduced Time-To-Market

Quick and easy provision of new servers and/or allocation of resources such as RAM and CPU into the infrastructure allowing businesses to compress development and design cycles. This enables faster time-to-market, minimising hardware-software integration lead-times.

4. Mobility

Webvisions(Australia) data mobility feature eliminates the risks and complexities associated with data migration necessitated by various IT tends such as server and storage consolidation, upgrade difficulties associated with lease rollovers, equipment replacements, storage relocation and optimisation, etc.


5. Availability, Reliability & Fault-Tolerance

The built-in redundancy of a large number of servers enables high levels of availability and reliability for applications. Webvisions (Australia) cloud infrastructure is designed in a way that loss of any one component will not result to system failure.

6. SLA/SLG Driven

Clouds are managed dynamically based on service-level agreements and goals that define policies including delivery parameters, costs, and other factors.
