MEANING OF CLOUD COMPUTING
Internet based services is called cloud computing. The cloud information is more than internet. The cloud is where to use technology when we needed it in very short interval of time. We don’t worry about the software installation, updating the desktop system and technology cost certainly minimise the because of cloud system. Barrett said the cloud can be both infrastructure and software which can be an application we access through the web that can be allow the cloud service:
Let us suppose if you are in anywhere of the cloud the operating system explorer can access a services that facility is based on beyond the internet. There are three criteria of cloud computing.
It is free of cost to get started.
Pay only as we used it.
Service access via web browser.
The system that appear in the form surrounding environment which has of cloud computing. Information and Communication Technology (ICT) system that allow stakeholders to use the internet to access cloud program whenever we need. Today, the emerging concept in cloud computing that broadcast reliable services delivered through next generation data warehouse. Customer will be able to access application and information and data from surrounding environment any time when we needed. In other sense, cloud to be single node for access for all the computing needs of customers. Computing in is available in any time with robust infrastructure.
The number of practitioners and researchers have attempted to define cloud in different way. Based on our empirical evidences what clouds are promising we describe, “A Cloud is a type of parallel and distributed system consisting of a collection of interconnected and vertualised computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers.”
Gartner cloud computing market rise about 21 percent so he define it is the term used to describe those system that allow developer, business and consumer to use the internet to achieve program and data at remote computer station.
Trends
In recent system, clouds in the form of cluster and grids. Clouds are emerging internet based system which have different in time interval. The term cluster computing, grid computing and cloud computing. Google trends, it can be observed that Cluster computing was in 1990s, from begaining from 2000 Grid computing became highlighted, and now Cloud computing started to become popular.
Technology
It has Network, Web2.0, Hardware virtualizations and software.
Network
The advance in grid computing that is networking technology, such as 3G and 8022.11(Wi-Fi), have been contributed significantly in the adoption of grid early 2008. Mobile device is good example of network cloud computing we access digital signal from open environment.
Web 2.0
The web 2.0 era has brought us technologies such as blogs, wikis and social networking platforms. These technologies provide users more feature rich environments, make it easier for users to generate and share web content. The individual network seems to make this less important. Similarly, individuals’ web pages can provide a relationship with business company ads web 2.0 application.
Hardware Virtualization
Hardware virtualization is the emerging technology that belongs virtualized resources like computation, networking and storage ensures resources. Hardware virtualization is the abstraction of the hardware resources into virtual representation of those resources. It includes the aggregating of multiple physical storage resources into a single virtual storage resource that can be managed centrally or logically divisional into virtual machines. Hardware virtualization has emerged as a powerful and practical way to get more from existing storage systems, consolidate resources and simplify the environment. It becomes key element to build infrastructure for workstation, data centers, and production environments. Hardware virtualization supports sharing of computing resources efficiently so that it increased utilization of the resources and decreased infrastructure cost effectively. Virtualization helps in workload consolidation, isolation and migration. Today virtualization is taken as relief for Cloud computing technology based businesses because of its ability for processing and handling hundreds of tera bytes of data per day. The hardware virtualization which provides broad range of storage, connectivity and presentation to virtual machines.
Software
In the cloud base system the software divided in to software as well as infrastructure service. In term of maturity, software in the cloud is important then hardware. In data center hardware and software which is called a cloud. The utility computing and SaaS is not including the private cloud. The term private Cloud belongs to internal data information and software. The software installation, update and maintenance control of its verson, so the client can access the software service anytime anywhere sharing, storing in cloud.
