What makes the Cloud so A scalable architecture is critical to take advantage of a scalable.

Cloud computing architecture refers to the components and subcomponents required for cloud computing. These components typically consist of a front end platform fat client, thin client, mobile device , back end platforms servers, storage , a cloud based delivery, and a network Internet, Intranet, Intercloud. Combined, these components make up cloud computing architecture. Cloud computing architectures consist of front-end platforms called clients or cloud clients. These clients are servers, fat or thick clients, thin clients, zero clients, tablets and mobile devices. These client platforms interact with the cloud data storage via an application middleware , via a web browser, or through a virtual session. The zero or ultra-thin client initializes the network to gather required configuration files that then tell it where its OS binaries are stored. This creates a single point of failure, in that, if the network goes down, the device is rendered useless. An online network storage where data is stored and accessible to multiple clients. Cloud storage is generally deployed in the following configurations: In order to be effective, the cloud storage needs to be agile, flexible, scalable, multi-tenancy , and secure. The software-as-a-service SaaS service-model involves the cloud provider installing and maintaining software in the cloud and users running the software from cloud over the Internet or Intranet. The users' client machines require no installation of any application-specific software since cloud applications run in the cloud. SaaS is scalable, and system administrators may load the applications on several servers.

Grid Computing Vs Cloud Computing When we switch on the fan or any electric device, we are less concern about the power supply from where it comes and how it is generated. The power supply or electricity that we receives at our home travels through a chain of network, which includes power stations, transformers, power lines and transmission stations. Grid Computing is a middle ware to co-ordinate disparate IT resources across a network, allowing them to function as whole.

It is more often used in scientific research and in universities for educational purpose. For example, a group of architect students working on a different project requires a specific designing tool and a software for designing purpose but only couple of them got access to this designing tool, the problem is how they can make this tool available to rest of the students.

To make available for other students they will put this designing tool on campus network, now the grid will connect all these computers in campus network and allow student to use designing tool required for their project from anywhere. Cloud computing and Grid computing is often confused, though there functions are almost similar there approach for their functionality is different. Let see how they operate- Cloud Computing Cloud computing works more as a service provider for utilizing computer resource Grid computing uses the available resource and interconnected computer systems to accomplish a common goal Cloud computing is a centralized model Grid computing is a decentralized model, where the computation could occur over many administrative model Cloud is a collection of computers usually owned by a single party.

A grid is a collection of computers which is owned by a multiple parties in multiple locations and connected together so that users can share the combined power of resources Cloud offers more services all most all the services like web hosting, DB Data Base support and much more Grid provides limited services Cloud computing is typically provided within a single organization eg : site Grid computing federates the resources located within different organization.

Utility computing is a good source for small scale usage, it can be done in any server environment and requires Cloud Computing.

Utility computing is the process of providing service through an on-demand, pay per use billing method. Based on the concept of utility computing , grid computing, cloud computing and managed IT services are based. Through utility computing small businesses with limited budget can easily use software like CRM Customer Relationship Management without investing heavily on infrastructure to maintain their clientele base.

Utility Computing Cloud Computing Utility computing refers to the ability to charge the offered services, and charge customers for exact usage Cloud Computing also works like utility computing, you pay only for what you use but Cloud Computing might be cheaper, as such, Cloud based app can be up and running in days or weeks.

Utility computing users want to be in control of the geographical location of the infrastructure In cloud computing, provider is in complete control of cloud computing services and infrastructure Utility computing is more favorable when performance and selection infrastructure is critical Cloud computing is great and easy to use when the selection infrastructure and performance is not critical Utility computing is a good choice for less resource demanding Cloud computing is a good choice for high resource demanding Utility computing refers to a business model Cloud computing refers to the underlying IT architecture Security concerns for Cloud Computing While using cloud computing, the major issue that concerns the users is about its security.

It protects the data from root kits and malware. As computing has expanded to different devices like hard disk drives and mobile phones, TCG has extended the security measures to include these devices. It provides ability to create a unified data protection policy across all clouds. Some of the trusted cloud services are site, Box. The administrative staff of the cloud computing service could theoretically monitor the data moving in memory before it is stored in disk.

To keep the confidentiality of a data, administrative and legal controls should prevent this from happening. Reason for using Cloud Computing:Reducing the cost made after communication for 28, employees and to provide advance features and interface of e-mail services to their employees.

Royal mail group, a postal service in U. K, is the only government organization in U.

From the HomePort @cobiacomm

K that serves over 24 million customers through its post offices and separate processing sites. Its logistics systems and parcel-force worldwide handles around million parcel a year.

And to do this they need an effective communicative medium. Learn how to design scalable, resilient, and highly available cloud apps Take a structured approach to designing your cloud applications. This cloud computing architecture e-book focuses on architecture, design, and implementation—considerations that apply no matter which cloud platform you choose.

How cloud apps work Data is stored and compute cycles occur in a remote data center typically operated by a third-party company. A back end ensures uptime, security and integration and supports multiple access methods. Cloud applications provide quick responsiveness and don't need to permanently reside on the local device.

They can function offline, but can be updated online. Cloud apps vs.

The term cloud application has gained great cachet, sometimes leading application vendors with any online aspect to brand them as cloud applications. Cloud and web applications access data residing on distant storage.

Both use server processing power that may be located on premises or in a distant data center.

A key difference between cloud and web applications is architecture. A web application or web-based application must have a continuous internet connection to function. Conversely, a cloud application or cloud-based application performs processing tasks on a local computer or workstation.

An internet connection is required primarily for downloading or uploading data. A web application is unusable if the remote server is unavailable.

If the remote server becomes unavailable in a cloud application, the software installed on the local user device can still operate, although it cannot upload and download data until service at the remote server is restored. The difference between cloud and web applications can be illustrated with two common productivity tools, email and word processing.

Gmail , for example, is a web application that requires only a browser and internet connection. Through the browser, it's possible to open, write and organize messages using search and sort capabilities. A CRM application accessed through a browser under a fee-based software as a service SaaS arrangement is a web application. Online banking and daily crossword puzzles are also considered web applications that don't install software locally. An example of a word-processing cloud application that is installed on a workstation is Word's Microsoft Office
