Some authors consider cloud computing to be a form of utility computing or service computing 2. Cloud computing types are service deployment models that let you choose the level of control over your information and types of services you need to provide. These three types differ in the amount of control that you have over your information, and conversely, how much you can expect your provider to do for you. On les appelle parfois « pile » de cloud computing, car elles s’empilent les unes sur les autres. Infrastructure as a Service (IAAS) is a form of cloud computing that provides virtualized computing resources over the internet. IaaS is a cloud computing model where virtualized infrastructure is offered to, and managed for, businesses by external cloud providers. Service offered via the internet are generalized as cloud computing and is categorized as IaaS, PaaS, FaaS, and SaaS, it is mainly divided into two types I,e, Deployment and Service models where the deployment model consists of the cloud computing services like Public Cloud, Private Cloud, Private and Hybrid which is used for applications like blog hosting, creation of a fresh application, Video, and Audio … Types of Cloud. D�@�2��FPT0t���Y@ virtual servers, hard disk space. They charge for cloud computing services based on usage. Cloud computing has been classified as four types of deployment models: public cloud, private cloud, community cloud and hybrid cloud [87]. h�Ėmo�6�� That's why we present the basic 7 fundamentals of cloud computing.

Cloud Computing The term “cloud”, as used in this white paper, appears to have its origins in network diagrams that represented the internet, or various parts of it, as schematic clouds . Cloud Computing is composed of three service models and four deployment methods. All these types of cloud technologies are being used for the different kind of services. The types of cloud computing are covered under Deployment Model. hޜ�mk�0ǿ�`oWN�mɆp�f�yфeP�BK�c�C��-���I�g��M��t��uw��x2B �BN����w��8GD"�D$�%I�"4b˜������R��}�pw2��F ;E�l6Q,R���9E��teH�0Hf�|o$���E���!%|�^vÙ�e����ue����tE��N)��ιR��M^���+�ˮ�u�����;��琔�W��|�VY� �{��y��Z�A�|]ܦ����7.

Either based on the deployment model, or on the service that the cloud is offering. Examples of Cloud Computing services includes Google Docs, Office 365, DropBox, SkyDrive etc.. Types of Cloud Computing. Thomas Erl has written a timely book that condenses the theory and buttresses it with real-world examples that demystify this important technology. %PDF-1.6 %���� These principles allow cloud computing to bring more cost-savings, automation and flexibility to the users, compared to using a traditional web service provider. 0 The most common and widely adopted cloud computing services are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). 1.3 Types of Cloud Computing Providers There are three kinds of cloud computing providers - Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The journey through these phases can take months or even years, and it’s best to go in measured steps. h�b```�Pɾ�A��X��#��C�E��ՃʼnC`B� ��H^��aMC��R�8�X���D*d?�߸�ؚ?�ӯ1������oq@h�5�!�{�ԃs � L\�L�1s��y0�� �,G�՘���x �C�j� �`�ڪ+6(>����4�~��wA�G����\�����‡/%%t8+h)p~c�Ǣ���A+b�$_�MK.�.�{R�Ɣ۞j���Sigii ��3� ���C�*�]���� ��*�b�4���D�4Hb#H�-N+�b�=qL�J��VLk�6C�J�%����p0��;�@6S�I404�5070500 � �� �X2@�l@^P�X"@jX�l ���`��D 1� ��� 2d�Z � Zk�� �Y�����C-u �{�A��& ����>q�zX&�[q%0�����u����p�� ��R The companies that offer these computing services are called cloud providers.

This was used to describe the new services. For example, Cloud services’ adoption is increasing among the mid-tier and small and medium businesses (SMB). Public cloud is open to all to store and access information via the Internet using the pay-per-usage method. “Cloud computing , more than most disciplines in IT , suffers from too much talk and not enough practice. With IaaS, companies can outsource for storages, servers, data center space and cloud networking components connected through the internet, offering similar functionality as that of an on-premises infrastructure. Therefore the security is the biggest problem of this system, because the services of cloud computing is based on the sharing. h�bbd``b`Z$k@�4 �z$�"N �� ���� ����W �o ��H(�1012pY��!�3&�0 0+ Cloud Computing 2.1 Types of Cloud Cloud can be of three types [20]. h�bbd``b`��@��DD ���9�@���?��0 ��� •NIST Definition of Cloud Computing "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."
