Cloud Computing is defined as storing and accessing of data and computing services over the internet. It doesn't store any data on your personal computer. It is the on-demand availability of computer services like servers, data storage, networking, databases, etc.

Cloud Application Architecture Guide

Cloud Computing is defined as storing and accessing of data and computing services over the internet. It doesn't store any data on your personal computer. It is the on-demand availability of computer services like servers, data storage, networking, databases, etc. The main purpose of cloud computing is to give access to data centers to many users.

Users can also access data from a remote server. Likewise other passengers also takes ticket and travel in the same bus with you and it hardly bothers you where they go. When your stop comes you get off the bus thanking the driver. Cloud computing is just like that bus, carrying data and information for different users and allows to use its service with minimal cost. The shape of this network design was like a cloud.

Why Cloud Computing? It requires a strong IT support and a storage hub. Not all businesses can afford high cost of in-house IT infrastructure and back up support services. For them Cloud Computing is a cheaper solution.

Perhaps its efficiency in storing data, computation and less maintenance cost has succeeded to attract even bigger businesses as well. The only thing that user must be able to run is the cloud computing systems interface software, which can be as simple as Web browser, and the Cloud network takes care of the rest. We all have experienced cloud computing at some instant of time, some of the popular cloud services we have used or we are still using are mail services like gmail, hotmail or yahoo etc.

While accessing e-mail service our data is stored on cloud server and not on our computer. The technology and infrastructure behind the cloud is invisible. Cloud computing helps small businesses to convert their maintenance cost into profit. In an in-house IT server, you have to pay a lot of attention and ensure that there are no flaws into the system so that it runs smoothly. And in case of any technical glitch you are completely responsible; it will seek a lot of attention, time and money for repair.

Whereas, in cloud computing, the service provider takes the complete responsibility of the complication and the technical faults. Benefits of Cloud Computing The potential for cost saving is the major reason of cloud services adoption by many organizations. Cloud computing gives the freedom to use services as per the requirement and pay only for what you use.

Due to cloud computing it has become possible to run IT operations as a outsourced unit without much in-house resources. Now in this Cloud Computing tutorial, we will learn the benefits of Cloud Computing. Following are the benefits of cloud computing: Lower IT infrastructure and computer costs for users Improved performance Fewer Maintenance issues Instant software updates Improved compatibility between Operating systems Backup and recovery Performance and Scalability Increased storage capacity Increase data safety Types of Clouds There are four different cloud models that you can subscribe according to business needs.

Following are the different Types of Clouds: Types of Clouds Private Cloud: Here , computing resources are deployed for one particular organization. This method is more used for intra-business interactions. Where the computing resources can be governed, owned and operated by the same organization. Community Cloud: Here , computing resources are provided for a community and organizations. Here the computing resource is owned, governed and operated by government, an academic or business organization.

This deployment method is called hybrid cloud as the computing resources are bound together by different clouds. SaaS Software as a Service SaaS or software as a service is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network internet. Through internet this service is available to users anywhere in the world.

SaaS users on the other hand, instead of purchasing the software subscribes to it, usually on monthly basisvia internet. Anyone who needs an access to a particular piece of software can be subscribe as a user, whether it is one or two people or every thousands of employees in a corporation.

SaaS is compatible with all internet enabled devices. Many important tasks like accounting, sales, invoicing and planning all can be performed using SaaS. PaaS Platform as a Service Platform as a service, is referred as PaaS, it provides a platform and environment to allow developers to build applications and services. This service is hosted in the cloud and accessed by the users via internet. To understand in a simple terms, let compare this with painting a picture, where you are provided with paint colors, different paint brushes and paper by your school teacher and you just have to draw a beautiful picture using those tools.

Software developers, web developers and business can benefit from PaaS. It provides platform to support application development. It includes software support and management services, storage, networking, deploying, testing , collaborating, hosting and maintaining applications.

It provides computing infrastructure like virtual server space, network connections, bandwidth, load balancers and IP addresses.

The pool of hardware resource is extracted from multiple servers and networks usually distributed across numerous data centers. This provides redundancy and reliability to IaaS. For small scale businesses who are looking for cutting cost on IT infrastructure, IaaS is one of the solutions. Annually a lot of money is spent in maintenance and buying new components like hard-drives, network connections, external storage device etc. What is Cloud Computing Architecture?

Cloud Computing Architecture is a combination of components required for a Cloud Computing service. A Cloud computing architecture consists of several components like a front-end platform, a back-end platform or servers, a network or internet service, and a cloud based delivery service.

Cloud computing comprises of two components front end and back end. Front end consist client part of cloud computing system. It comprise of interfaces and applications that are required to access the Cloud Computing or Cloud Programming platform. Cloud Computing Architecture While back end refers to the cloud itself, it comprises of the resources that are required for cloud computing services.

It consists of virtual machines, servers, data storage, security mechanism etc. It is under providers control. Cloud computing distributes the file system that spreads over multiple hard disks and machines. Data is never stored in one place only and in case one unit fails the other will take over automatically. The user disk space is allocated on the distributed file system, while another important component is algorithm for resource allocation.

Cloud computing is a strong distributed environment and it heavily depends upon strong algorithm. Virtualization is a partitioning of single physical server into multiple logical servers. Once the physical server is divided, each logical server behaves like a physical server and can run an operating system and applications independently. They are fast, cost-effective and less time consuming.

For software developers and testers virtualization comes very handy, as it allows developer to write code that runs in many different environments and more importantly to test that code. Storage Virtualization: It is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.

Storage virtualization is commonly used in storage area networks SANs. Server Virtualization: Server virtualization is the masking of server resources like processors, RAM, operating system etc, from server users.

The intention of server virtualization is to increase the resource sharing and reduce the burden and complexity of computation from users. Virtualization is the key to unlock the Cloud system, what makes virtualization so important for the cloud is that it decouples the software from the hardware.

Usually hard disk has a lot more space than memory. Although virtual disks are slower than real memory, if managed properly the substitution works perfectly.

Likewise, there is software which can imitate an entire computer, which means 1 computer can perform the functions equals to 20 computers. 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.

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 : Amazon 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 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 Amazon, 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.

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.

 Ах какие мы скрытные. А ведь у нас в Третьем узле нет друг от друга секретов. Один за всех и все за одного. Сьюзан отпила глоток чая и промолчала. Хейл пожал плечами и направился к буфету. Буфет всегда был его первой остановкой.

Беккер изобразил улыбку. - Я должен идти. Он извинился перед немцем за вторжение, в ответ на что тот скромно улыбнулся. - Keine Ursache. Беккер вышел в коридор. Нет проблем.

Когда он проходил мимо лифта, дверцы открылись.

Для Сьюзан это не составляло проблемы: она была безмерно счастлива в своей скромной двухкомнатной квартире, водила вольво и довольствовалась весьма консервативным гардеробом. Но вот туфли - совсем другое. Даже во время учебы в колледже она старалась покупать самую лучшую обувь. Нельзя дотянуться до звезд, если чувствуешь себя ущемленной, - сказала как-то ее тетушка.

Смотрите сюда! - Он попытался поднять левую руку.  - Кто теперь напишет материал для моей колонки. - Сэр, я… - За все сорок три года путешествий я никогда еще не оказывался в таком положении. Вы только посмотрите на эту палату. Мою колонку перепечатывают издания по всему миру.

Он снова с силой пнул ногой педаль стартера. Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся. Беккер изо всех сил цеплялся за жизнь. Мотоцикл, виляя, мчался по газону и, обогнув угол здания, выехал на шоссе. Халохот, кипя от злости, побежал к такси.
