One might ask how does cloud computing work? Cloud computing architecture refers to the components that work together to form cloud computing. The architecture behind cloud computing involves two different parts, the front end and the back end. Each part connects through the internet and works together. The front end structure is also referred to as the clients. This is the part or side of the server that the user interacts with and sees. For the user to connect and interact with this end, they need to have access to a computer with internet. An example of the front end structure being used is a user logging on the internet to check their email. Again, millions of people check their email every day and do not realize it is part of cloud computing. The other part of cloud computing architecture is called the back end structure. This part is responsible for the service that make the cloud work. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. () The back end service is made up of Software as a Service (SaaS), Platf...
The idea of accessing, storing, and processing data from online server or virtual server instead of local server is called as Cloud computing. When we store data in our hard disk which is very near to computer that is called as local storage and computing but Cloud computing doesn’t access data from our hard disk.
The second cloud infrastructure that I would like to describe is the Software as a Service model, which is also known as SaaS. The SaaS model provides a broad scope of devices that are able to access software programs from one company’s applications. System as a service was developed to run applications from any device or user that has permission from the host. The book states, “Online email services, such as Gmail and Yahoo!, are good examples of SaaS” (Jill West, 2016). Cengage Learning made the Software as a
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
INTRODUCTION: With cloud computing, Amazon has enabled the usage of internet and central remote servers to maintain data and applications and created an environment where connectivity and availability is unobtrusive and prevalent. Amazon offers two options for hosting applications and databases. Amazon EC2 with Elastic Block Storage allows one to run a MySQL database server on Elastic Compute Cloud, an Infrastructure-as-a-Service provider, with Elastic Block Storage (EBS). Meanwhile, another option called Amazon’s Relational Database Services (RDS) is a scalable relational database in the cloud with high availability.
Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
You can define distributed computing many different ways. Various vendors have created and marketed distributed computing systems for years, and have developed numerous initiatives and architectures to permit distributed processing of data and objects across a network of connected systems. They have developed a virtual environment where you can harness idle CPU cycles and storage space of tens, hundreds, or thousands of networked systems to work together on a particularly processing-intensive problem. The growth of such processing models has been limited, however, due to a lack of compelling applications and by bandwidth bottlenecks, combined with significant security, management, and standardization challenges. A number of new vendors have appeared to take advantage of the promising market; including Intel, Microsoft, Sun, and Compaq that have validated the importance of the concept.1 Also, an innovative worldwide distributed computing project whose goal is to find intelligent life in the universe--SETI@Home--has captured the imaginations, and desktop processing cycles of millions of users and desktops.
Cloud computing refers to hosting services provided over the Internet. The Internet connects the users to the subscribed remote database, where all the consumers under the cloud service will use a pooled set of resources with the infrastructure cost being shared across everyone.
Our research group has to agree that implementation of cloud computing to PCB companies can be done within the next few years because the IT industry being used by PCB companies will drastically change as the research group knows. Most or some employees may not fully understand the concepts or even grasp the basics of cloud computing in this present era but it takes time for them to learn. Personnel of PCB companies especially upper managers would expect good results and benefits both financial and technical from cloud computing in this fast moving years run by society depending on tons of IT platforms. Managers and employees would expect a statement from favorable to high ratio of profit to budget. The business model of PCB companies are based on helping managers and employees on how to move efficiently and effectively while saving costs and earn more profit to improve productivity and sales. The IT industry will still develop and invent a lot of ways to help people from individuals at their homes to every employee at worldwide companies. In the future, there may be innovations and inventions better than cloud computing and better ways of assistance to it. Cloud computing could wipe out traditional IT service providers because for PCB companies, the coming services wave will be very disruptive. More customers and consumers will demand more PCBs, integrated circuits (IC), solders, coppers, and other electrical and electronic components needed. PCB companies need raw materials like copper, paper, epoxy and glass fibers to keep up with the growing demands. The ways of processing like etching, lamination, drilling, plating, coating, soldering, screen printing, testing, protection, packaging and quality control are done all or most au...
The term used as cloud computing is a wide term. It includes a wide range of different services. Cloud computing is also known as on demand computing. This name is given to cloud computing because it provide online services to different persons on computer by sharing processing resources in addition with data to computers depending upon different demands.
The cloud is a computing network of remote, servers hosted on the internet and used to store, manage and process data in place of local servers or personal computers. There is a rich, complex, and shared data store in the cloud (Oxforddictionaries.com, 2014). In addition. in the could computing, there is also a thing used to explain a range of computing concepts that include a large number of computers attached through a real-time communication network like the internet. In since, cloud computing is a synonym for distributed computing over a network and that means the ability to run a program or an application on many connected computers at the same time.
Grid computing is defining the combination of computer resources from many numbers of administrative domains to reach the existing goal. The grids have heterogeneity and geographic disreputability in its resources. Grids can solve grand challenge applications using the Computer Modeling, Simulation and Analysis. Grids can be available in the form of distributed computing and differs from the other architectures like as a cluster. Grid computing can overcome the limitations such as the conventional shared computing mood and to become a principal trend in the distributed computing system. Grid core service is the Centre of grid computing which can take the charge of entire grid system in order to give definite grid system with its work effectiveness. The grid core service is an important part in the grid computing and the task scheduling strategy is the part of grid core service. The grid resources are required more number of tasks and the system can optimizes the resource through scheduling the tasks reasonably.
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
Cloud computing is the ability to use programmes and data on a remote server somewhere in the world that is connected to the internet to get work done. In cloud computing there are 3 types of cloud computing SaaS, PaaS & IaaS. Information is stored on servers, you host your IaaS (infrastructure as a service) service on a server or multiple servers. This is expensive to do for the average person so companies have been set up to do this for you like amazons Elastic Computing and you pay for how many servers you use over a month and you pay for storage. Programmes are run in virtual machines (virtual computers) on servers so users can use these services over the internet at ant time.
Abstract: Fog computing extends cloud computing, cloud computing provide data, compute, storage, and application services to end-user, also the fog computing also provide the services like data, compute ,storage and application to end user. But in cloud the main problem that occurs is security and now a days security and privacy both are main concern that needed to be considered. Fog Computing is not a replacement of cloud it is just extends the cloud computing by providing security in the cloud environment. With Fog services we are able to enhance the cloud experience by isolating users’ data that need to live on the edge. The main aim of the fog computing is to place the data close to the end user.The securityissues are mentioned in this paper.
