  7. Document control, security, and competitiveness – The document control is very important for everything. Yes, the collaborate on documents and conflicting file contents are something a little more streamlined, if we some how loose our laptop or any other storage device it makes billion dollar business problem. For your information, the cloud computing software can be operated  and accessed remotely.

Disadvantages of Cloud Computing

Here we mentioned some of the important draw backs of cloud computing. The downtime is one of the major drawbacks in the cloud computing. It mainly needs an internet connection to work frequently or else it will fail to work. The cloud service provider will manage and safeguard the infrastructure of deployment.

At some instances the small-scale projects might stop your instances when the systems are unused, otherwise its just a waste of energy and time. It will make more expenditure in terms of cost proxy for usage. However, the cloud computing may fall and goes over reliability standards that will finally improve the cloud computing platform scale.

History of Cloud Computing

History of Cloud Computing | Cloud Computing Tutorial for Beginners

For your information, the cloud computing word origin is unclear. The word cloud is described a visually appear from agglomeration where the old programs network schematics server with a circle network diagram. The cloud symbol is going to represent computing devices in the ARPANET which was developed in the year of 1977. In 1981, creates a CSNET which provides a predecessor to the connection of internet. Thus the term cloud is referring to the platform of computing distributor.

In the year of 1960, the initial concept of cloud computing became popular by the RJE remote job entry. The data center model was developed by IBM mainframes predominant 1970. In the year of 1990’s, those are all having the telecommunication companies, point to point data circuit’s comparable quality of service. Since 2000, the cloud computing model became popular. Most of them were used to develop the cloud computing. In the year of 2008, NASA enhanced the European commission which was a funded project. Then they developed a quality of service as private, hybrid clouds and for the cloud federation. In the year of 2008 April month, Google released the cloud computing based app called Google app engine. Then, in the year of 2012, Google launched the Google compute engine where the preview model of Google computes original engine model developed and released in 2013, December.

How does Cloud Computing Work

The cloud computing system is a significant workload shift. The local computer does not come to running application. The cloud computing is a metaphor internet with cloud symbols mostly used on the internet diagram. The virtualization is connected through the internet which acts as a cloud. The information is stored on physical server regards to iCloud. There is some various kind of cloud computing services  available for the different needs with a price which is varied depends on your needs.

How does Cloud Computing Work

Thus the cloud computing can save important photos, contacts, videos, and documents in one place. If all documents are stored in one place, anyone can see the document. There is no privacy when comes to access your files. Also, we can easily transfer the new compatible devices like mobile phone, tablet, and computer with a new technology which is going to become widespread.

Types of Cloud Computing

Types of Cloud Computing | Cloud Computing Tutorial for Beginners

Cloud Computing is broadly described in various ways. People who all are seeking to know about different cloud computing can check out here. They are

  • Public clouds
  • Private clouds
  • Hybrid clouds
  • Community Clouds

Public Cloud

One should be aware of that the public cloud is said to be the internet. For the information, thus the service providers are mainly using the internet for making the resources available for the people who want to use the internet often. These are the type of clouds which are generally providing the best economies and also in terms of expenses. It will cost you that is based on how much of internet have been used.

As per the sources, we must admit to knowing that most of the people are easy to recognize. It is the service that is mainly given for the virtual form of environment. For information, it is the cloud that is mainly built from the physical types of resources for the users to follow ahead. It is also readily available in terms of using the internet on the public platform.

Important examples of Public cloud

We all know that the prominent examples are, the cloud computing which is largely used in the public cloud. Also, it is indicating that the cloud computing is available on the public platform. People who all are looking for the example can follow here to understand.

  • Atmosphere develops using cloud
  • Website hosting is largely included cloud hosting
  • It also includes software applications
  • Also, encourages the services for cloud storage

Thus the public clouds are highly used in terms of offering a long for the people who all are working on it, individually. But it offers the less security when coming to the user who works with private clouds. However, the important thing is that most of the different types of enterprises prefer public clouds because it has the potential to satisfy the process. You can also easily expect the collaboration of document in online and web mail.

Public Cloud vs Private Cloud | Cloud Computing Tutorial for Beginners

Excellent features of Public Cloud

Here we are sharing some of the important features that most of the users wanted to know about. Let’s check out that what all are the main benefits that you can expect from this process.

  • Costing of efficacy style
  • Clients wherever they are located, it gives you best location.
  • It is high reliability in terms of usage.
  • Flexible to work
  • It is highly cost effective

Private Cloud

Unlike the public clouds, private is quite expensive in terms of economies. This is large works for the large type of enterprises instead of working for a small and medium type of enterprises. It is the highly secure-able form that largely satisfies the users.

One must know as an outcome, and this public cloud computing is largely working for the business and adaptable as per to the environment as well.

Also, the cloud deployment from private and public is always different from others. When coming to the basic benefits of private cloud computing, it highly delivers the self-service, developing multiple types of machines for a various complex type of computing jobs and more. However, the private cloud has some of the disadvantages as well. Yes, instead of working with the third party, it should be able to manage the private cloud. But, as an outcome, it carries the same maintenance and expenses. Also, the private cloud additionally includes the cloud management tools, virtualization and cloud software.

Hybrid Cloud

With the help of hybrid clouds, a large number of companies can get the benefits in terms of managing the internal private cloud. To recover the issue this is easy because of low-cost. On the other side, Business continuity and disaster recovery it happens due to a cloud, it will mainly allow recovering in a quick time of period.

Hybrid Cloud | Cloud Computing Tutorial for Beginners

People who all are looking for an enterprise which deploying a private cloud to host critical works but as a third party cloud provider of the public. When coming to hold the backup data, this hybrid cloud will simply use the Amazon storage device. One must know that the hybrid cloud is widely valuable for changeable works. On the other side, hybrid cloud mainly works with big data processing.  For example, most of the companies are largely using hybrid cloud to retain its sales, data, test and more.

In this cloud, despite its positive, it also delivers the challenges of management, business and technology. It also requires an API compatibility along with the connectivity of the reliable network. When coming to this cloud, we can expect some connectivity issues as well to face at anytime. To prevent these issues, most of the organizations go over hybrid overload works which helps to operate with the providers of a public cloud. One should understand that this workload is quite way higher of complications in terms of testing and designing. On the other side, workloads are largely helped for the hybrid cloud redesign to welcome the providers.

Community Cloud

It is said to be the multi-tenant infrastructure which highly helps to share among a number of organizations with the help of several groups and computing forums. For the information, most of the forums and concerns are working related to the regulatory fulfillment. These are the requirements in performance wise, hosting the applications which mainly need a response time in a quick period. The ultimate aim of the community cloud is to allowing many organizations for turning up the benefits along with public cloud. One should be very much aware on off or on premises which are mainly governed by the organizations or managed service provider.

Community Cloud | Cloud Computing Tutorial for Beginners

Thus the cloud is mainly representing the significant shift where the computing largely depends on it. So, showing the interest towards the cloud will help to bring the service based technology to the globe with clustering, data centers, OS and more. To know more about cloud computing and its difference can follow the above-mentioned above. Hope it will be useful for all the seekers.

Cloud Computing Services

Cloud computing is one of the software models and computing infrastructure. The cloud computing allows a various computing capabilities users and enterprises. The cloud computing world originate unclear. If we use it in the business cloud computing model, cost is very low, then the business organization correctly uses the cloud computing model, and you can neglect the unwanted layers of management. The cloud computing service model is based on the organization needs. And moreover, we can improve the cloud computing service model for business needs.

Cloud Computing Services | Cloud Computing Tutorial for Beginners

Kinds of cloud computing service models

There are three different kinds of the cloud computing service models which are shown below. The organization must be selected what actually they need for cloud computing service models.

  • IaaS – Infrastructure as a Service
  • PaaS – Platform as a Service
  • SaaS – Software as a Service

Software as a Service (SaaS)

Software as a service is going to replace traditional licensed software on the subscription basis. In the software as a service, the model is a centrally hosted when comes to the cloud. We can also operate the most of SaaS application through online and we can use this software as a service cloud computing models on the internet without downloads or installation process. The software as a service cloud computing software model is mostly used in the payroll processing software, DBMS software, CRM (customer relationship management), MIS (management information system), ERP (enterprise resource planning), and the information technology, etc.

Software as a Service (SaaS) | Cloud Computing Tutorial for Beginners

In the year of 2010, Gartner Group estimates the software as a service cloud computing service model sales which reach ten billion dollars. The customer relationship management has grown up with the large market for SaaS. There are two main kinds of software of service model they are vertical SaaS (software as a service) and horizontal SaaS (software as a service).

Vertical software as a service

The software is going to be developed and used only for particular industries like healthcare, real estate, agriculture, finance industries, etc.,

Horizontal software as a service

The horizontal software as a service cloud computing service model is mostly focused on a software category. For example, the horizontal software as a service is considering as the marketing, sales developer tools and the HR human resource.

SaaS examples – Sales force, Google app, concur, citric GoToMeeting, Cisco WebEx

Common SaaS use case – to replace the traditional device’s software.

Technology analyst examples – Bill pray (Gartner), Amy DeMartin (Forester)

Benefits of SaaS

We can access the administration easily. The automatic update process, the patch management and the compatibility level are high. All users must have the same versions of software like software as a service. It is easy to collaborate for the same kind of reason. The SaaS is like a global accessibility.

The storage as a service is a business model for smaller companies or for individuals. The communication as a service is one of the software as a service cloud computing model. The enterprise communication solution is responsible for hardware and software managements. The cloud computing set up cost is based on the organization needs.

Infrastructure as a Service (IaaS)

The infrastructure as a service layer is one of the cloud computing service models. The infrastructure as a service layer is a very first and major layer. A few years back, if you want to run your business. You must need the application in control company website and the office hardware in local applications. The infrastructure as a service layer is provisioning the enterprise systems and computing resource required. The IaaS includes hardware, storage, networking components and the servers.

Infrastructure as a Service (IaaS) | Cloud Computing Tutorial for Beginners

The physical infrastructure is typically moved on offsite and service providing virtualization environment. The cloud computing service model can be improved by the organization requirements. The infrastructure as a service can be outsourcing needs to hardware. The maintenance of hardware and software both are accessing anytime.

Examples for the IaaS layer – Amazon, Microsoft, VMware, Red Hat and the Rack space.

Benefits of IaaS

If we use infrastructure as a service, layers are used in the business model. We can use the CPU central processing unit dynamically. The memory and the storage configuration is mostly based on the organization needs. You may access the computing service model in the information technology. We can eradicate the unwanted investment in the hardware. The IaaS cloud computing service model is a platform which can be used as a customization option and privacy.

Disadvantages of IaaS

The infrastructure service as a cloud computing service model will work only on the internet and it is one of the major drawbacks in the IaaS layer well. In case one or two days are not available on the internet, then the whole work will get corrupted. The IaaS layer cloud computing service model highly depends on the virtualization services.

Platform as a Service (PaaS)

The platform as a service (PaaS) layer is one of the second major layers in the cloud computing service models. It is also known as the middle-ware. If the platform as a service layer is used in the business organizations or the institutes, it will save time and resources. Thus the PaaS is developing and deploying applications in the scattered workforce. However, the web application and management application are the collaboration tools in the operating systems.

Platform as a Service (PaaS) | Cloud Computing Tutorial for Beginners

Thus the platform allowing business need to develop, manage the application and run typically associated with the consumer which controls software deployment.  The software developers, information technology professionals, and business leaders may be deployed next level of generation of application in the cloud service models.

Examples for the PaaS layer – Google app engine, Microsoft Azure, Engine Yard, sales force owned Heroku, AppFog, Mendix and standing cloud.

Benefits of PaaS

The main advantages of PaaS are reducing the higher level complexity. The overall development, infrastructure maintenance and enhancement of the applications are easy to access whereas the multiple developers of the platform as a service will be improved on the basis of organization needs. Cost reduced the two major important benefits of platform as a service and increased by speed.

Disadvantages of PaaS

The platform as service developers may not be using the conventional tools. For examples, relational database with the unrestricted joins and another possible drawback is locked into a several platforms. Moreover, the most of PaaS cloud computing is relatively with lock-in free.

What is Cloud Computing Architecture?

The cloud computing architecture must need some kinds of components and sub components. To make cloud computing, there are two various platforms available in the component which makes cloud computing architecture. The front end platform is like a fat client, thin client, and mobile device. The back end platforms are making to use server and storage purpose. Thus the network based is large to provide an internet, intranet and inter cloud. The cloud computing services or delivery is based on something which is mentioned here. The cloud based delivery first one is software as a service, then the second one is developing as a service, and the third one is data as a service, the fourth one is the platform as a service, and the final one is infrastructure as a service.

The online network storage will access to multiple clients whereas the cloud computing storage consists of the private cloud, public cloud, and the community cloud. Thus the above combination of three clouds is known as the hybrid cloud. However, the server based application delivers the cloud computing resources and the applications are made to use on mobile and desktops. The front platform cloud computing is most widely used to visible interface through their web enabling devices. The back end cloud computing platform is to deliver cloud computing services as well.

Grid computing vs. Cloud Computing

The grid computing computer can solve the problems more than one together. The problems involving a maximum number of crunching and can be easily paralleled. The cloud computing is evolving from the grid computing. The grid computing services are providing the resource provisioning. The grid computing may or may not depends on the cloud computing. The system administrator and integrator is maintained in the cloud. Grid computing requires software programs on a large number of systems image to the several thousand computers.

Grid computing vs. Cloud Computing | Cloud Computing Tutorial for Beginners

The both of grid computing and the cloud computing are scallable. We can accomplish a load balancing of the applications running separately. The variety of connections and the operating software like open-source and closed source software are through the web services. A large number of data can be transferred at a given particular time. In this storage capacity is varied from the number of users going up and down. The service level agreement SLA based on the cloud computing and grid computing availability of saying ninety-nine percent.

If use grid computing, the amount of distribution large for computationally. The computational grid computing is focused on intensive operations standard and high central processing unit CPU. The grid creates a service for the low level and the high-level functions. A grid combines both hardware and software infrastructure. The grid computing is most widely used in the academic research. The clouds are large pool usable and the accessible resources. The grid infrastructure will provide a customized service.

Utility Computing vs Cloud Computing

The utility computing and grid computing both are sharing the subsets of the latter with cloud computing. The utility computing involves a network bandwidth and software on the basis of requirements and demand basis. The considered products organized as a public utility become the basis of new and important industry. Although, the utility computing and the grid computing were procured everything by cloud computing. Cloud computing is not specific networks and resources pronounced.

Note that utility computing can work and can be implemented without cloud computing. The utility users may pay for the resources used in the computer services. However the cloud computing and utility computing both is virtualization of the resources. At the same time, compare grid computing and cloud computing. The grid is weaker than the cloud computing. Here always virtualization is involved in the utility computing. The utility computing refers to services and charges that customers used for the utility services.

Most of the time utility computing is connected with the cloud computing. The cloud computing infrastructure is a good choice for resource demanding application. The utility computing does not run in the cloud computing server environment. It is unreasonable for smaller usage and economically applied on a smaller scale. The utility was to be procured dynamically allocated or upgraded in the systems. The utility provides a large scallability and cost saving process for back bone of cloud computing. The utility storage device networks handle peak workload and the projected growth.

Finally, we can say that the grid computing is weaker than the cloud computing. The major drawback in grid computing is that the storage level is very low. The utility computing will be used or consider in the business model. It will support only a specific technology. The cloud computing supports the utility computing, but utility never supports cloud.


The main technology of cloud computing is virtualization. The virtualization is nothing but, to create something new from others. The virtualization is mostly used to divide a single physical server into the multiple logical servers. If the physical server is divided into performing some logical server like each logical server will perform on same physical server. Now Microsoft Company provides the virtualization service.

What is Virtualization?

The virtualization is creating various from others like that a server, a desktop, a storage device, an operating system or the network resources. The operating systems and the hardware are known as the hardware virtualization. Virtualization is mostly used to divide a single physical device into some logical servers. The machine called virtual machine is going to create a host machine. The host virtual machine is referred as a guest machine.

Virtualization | Cloud Computing Tutorial for Beginners

Types of Virtualization

The different kinds of virtualization are available now are shown below. Such as

  • Hardware virtualization
  • Software Virtualization
  • Server Virtualization
  • Storage Virtualization
  • OS virtualization
  • Windows Virtualization

Hardware Virtualization

Hardware Virtualization

The hardware virtualization is most widely important things for creating a virtualization.  The virtual machine manager or software can install to the hardware system. It’s known as the hardware virtualization. The hardware virtualization is to perform a logical abstraction of the component or functionally required to run the various operating systems. The hardware can control the virtualization was called a hyper-visor or the virtual machine monitor. The hardware virtualization provides architectural support facilities to build a virtual machine. The Hardware virtualization is mostly used to do by the server platform. The controlling virtual platforms server machine is going to control a physical server.

Software Virtualization

Software Virtualization

The software virtualization allows a single host computer. The single host computer will create run one or the more virtual environments. The software virtualization is most widely used to emulate the complete computer systems. The computer systems are going to allow the operating systems to be run for multiple purposes. If you are used to Linux, open source operating software can run a personal computer. The naively run a Microsoft windows operating system is one of the closed source software. Which is used to inverse the running windows as a guest on Linux. There are some kinds of subcategories software virtualization available. Which is shown in below like that, first one is platform virtualization software and the second one is the emulation software, the third one is free virtualization software, and the last one is virtualization related software for the Linux.

Server Virtualization

Server Virtualization

The virtual web server is to provide a low-cost web hosting services. The separate computer web server, dozens of the virtual servers can access the same computer. The server virtualization has many benefits like that runs in an own operating systems. The virtual server also runs in a separately rebooted with one another. The server virtualization can reduce the cost because it requires less number of hardware which will help to avoid spending money. The server virtualization provides a conserves space through the consolidation as several machines. The machine can be consolidated into a single server running multiple virtual environments. We can use the minimum number of physical servers to reduce the hardware maintenance.

Storage Virtualization

Storage Virtualization

The storage virtualization is going to help the storage administrator performance. The storage server can backup arching and recovery more easily within a minimum amount of time. The actual complexity of storage area network administrators can be implemented while the software application used in the hardware server or software hybrid appliances. The storage virtualization can be divided into the two kinds of virtualization category they are shown below. The first one is blocked virtualization and the second one is file virtualization. The storage virtualization is used to enable better functionally and more advanced features in computer data storage.

OS Virtualization

The OS operating system virtualization is known as the containerization. The operating system virtualization is a multiple isolated user space instances. The instances called as containers. The real computer programs on an ordinary persons computer operating system. The individual person operating system can allow seeing all the resources of that device assigned by the container. The operating system features can be used to the various implementation of the standard mechanism. The apparent root folder processes were to be isolated. The isolating mechanism provides a resource management. The resource management features are to limit the impact of container activities to other containers.

Windows Virtualization

The windows virtualization personal computer is a virtualization program. The virtualization programs based on the Microsoft windows. The Microsoft Company has released the windows version as a free product. The older version will support the range of host and guest operating systems. Virtual standard IBM personal computer compatible device and its associated with the hardware devices are the Linux operating system which is one of the open source software. In the virtual machine, additions includes all the essential drivers for the Linux operating systems.

Windows virtual personal computer is a predecessor’s version which supports only Microsoft operating systems. The originally required hardware virtualization supports which allow it to run the hardware support. The windows virtual PC is the application used in world wide. The windows platform production will be multiple monitors and supports for vista as both host and guest.

Benefits of Virtualization

  • Here we mentioned some of the benefits of virtualization are shown below. Read one by one carefully and utilize it. Such as
  • While the build up a virtualization structure, producing heat is very low.
  • Very low cost.
  • Redeploy is much faster compared to others.
  • Easy to backup.
  • Better testing.
  • No vendor locks in.
  • We can recover the disaster time.
  • Single minded server.
  • Easy to migrate the cloud.
  • Migrate to the virtual machine.
  • Infrastructure management.
  • Instant capacity.
  • Isolate the application.
  • We can reduce the data center foot print.
  • Faster server provisioning.
  • You can increase up-time.
  • Help move things to the cloud.

Virtual machines relieve the typical headaches through an administrator. You can easily use virtualization data centers to migrate a simple physical file server into the virtualized technology. When you are choosing to implement the business or an IT organization, virtualization is better option comparing with others.
