2 Hw des Clud Cmputing Wrk? By Carl Mazzanti, CEO, emazzanti Technlgies We are already in the Clud Clud Cmputing is Internet- based prcessing, where cmputing infrastructure, sftware applicatins, business prcesses and cllabratin and infrmatin capabilities are delivered t cmputers and ther devices (such as smart phnes and tablet PCs) n demand ver the Internet. S, the "clud" we're talking abut is nt a white puffy thing in the sky, it's the metaphr used t describe capabilities that are available via the Internet. Clud Cmputing is the latest buzz wrd arund a number f Internet services that already are available as well as thse services that will yet cme. It's the next phase in the Internet's evlutin thugh we've already started ur relatinship with the clud sme time ag. Familiar Clud- Based Services If yu use any f the ppular public services like Yah!, Ht Mail r Gmail, yu're already taking advantage f clud cmputing. Yur Inbx, Sent, Drafts, Deleted and Cntacts files are hsted n the prvider's cmputer servers. If yu als signed up fr additinal services frm prviders such as Micrsft Messenger and Ggle Gmail, yu might als be taking advantage f instant messaging r blgging features, als clud- based services that make cmmunicating with friends, family and business assciates easy and efficient. If yu've ever used Skype t make phne calls r hld vide cnferences, this is anther clud- based service that reduces csts and makes efficient use f ur time. Sftware as a Service- Smething Old, Smething New Thugh Sftware- as- a- Service (SaaS) has been arund a number f years and is technically n mre r less a frm f Clud Cmputing, it is als evlving int sme pretty interesting pprtunities fr users, n bth the persnal and business level. 2

3 Again, public is a great example f SaaS that we've enjyed fr a lng time. Hwever, the SaaS r Clud Cmputing landscape is mrphing int a new generatin f capabilities. Fr example Micrsft Office Live, Office 365 (cming sn) and Ggle Dcs ffer web- based wrd prcessing, spreadsheets, presentatin capabilities and data strage. These clud services give us instant access t pwerful dcument creatin and management tls that are always available regardless f gegraphy. This nascent capability is the ultimate evlutin in mbility and prductivity. Clud Cmputing Characteristics Clud cmputing requires searching fr a clud prvider. Whether yur clud is public, private, r hybrid, lk fr scalability, access, interface, and usage mdel: Scalability. The clud is elastic, meaning that resurce allcatin can get bigger r smaller depending n demand. Elasticity enables scalability, which means that the clud can scale upward fr peak demand and dwnward fr lighter demand. Scalability als means that an applicatin can scale when adding users and when applicatin requirements change. Self- service access. Clud custmers can get clud services withut ging thrugh a lengthy prcess. All yu have t d is request a specific amunt f cmputing, strage r sftware frm the service prvider. After yu use these resurces, they can be autmatically shut dwn by discnnecting frm the Internet. General User Interface (GUI). Clud services shuld have standardized interfaces, which prvide instructins n hw tw applicatin r data surces can cmmunicate with each ther. A standardized interface lets the custmer mre easily link clud services tgether. Free r Service Use Metering. Right nw there are a number f free Clud Services fr basic dcument preparatin capabilities fr example. Sme targeted clud services such as payrll r accunting sftware are based n a pay- as- yu- g mdel r mnthly/annual fee. Span f Capabilities and Risks Clud Cmputing is usually classified int three categries: (1) Infrastructure as a Service (IaaS)- strage and cmputing resurces; (2) Platfrm as a Service (Paas)- black bx infrastructure that develpers can build applicatins n tp f; (3) Sftware as a Service (SaaS)- where a service prvider hsts sftware service n ff- site servers. 3

4 Cmputing n the clud requires vigilance abut risks such as security, manageability, standards, gvernance, and cmpliance: Clud security. The same security principles that apply t n- site cmputing apply t clud cmputing security. Fr example: identity management- persnal identify infrmatin needed t access any cmputer netwrk assciated resurce; detectin- identifying real vs. illegitimate activity; Encryptin- infrmatin asset cding t prtect data. Clud manageability. The ability t have a cnsistent view and management capabilities acrss physical and clud- based envirnments. Yu need a cnsistent view acrss bth n- premises and clud- based envirnments. Clud standards. Clud standards ensure inter- functinality, s yu can take tls, applicatins, virtual images and use them in anther clud envirnment seamlessly. Clud gvernance. Gvernance identifies respnsibility fr the plicies and prcedures that need t be fllwed. Clud gvernance requires gverning wned infrastructure and infrastructure nt wned as well. Data in the clud. Managing data in the clud requires data security and privacy, including cntrls fr mving data. It als includes managing data strage and the resurces fr large- scale data prcessing. Hw Clud Cmputing Can Reduce Csts Mst small and medium size businesses are very interested in reducing csts where ever pssible. Public r private clud cmputing slutins are wrth investigating. Bradly speaking, Clud Cmputing can benefit yur cmpany in the fllwing ways: Lwer up- frnt investment Dynamic scalability Enrich experiences acrss PCs, phnes and brwser Rapid deplyment Distributed disaster recvery scenaris Reputatin- based technlgies (technlgies that cme frm majr prviders) Mre specifically, public r private- based Clud Cmputing can, fr example, help reduce IT csts. Belw are five additinal ways f ding s: 4

5 The public clud mdel ften has the ptential t deliver the mst dramatic cst savings: 1. Pay as yu g. This is perhaps the mst cmpelling f any clud value message. By mving applicatins and wrklads t a public clud platfrm, internal IT staff can instantly adjust resurces up r dwn, depending n the immediate needs f any particular wrklad. 2. Cntrl server prliferatin. Placing wrklads in the clud means thse wrklads n lnger require dedicated server capital investments. While the clud isn t free, running applicatins clud- based servers allws the pssibility f reducing r eliminating that cst. 3. Data center cst reductins. Fewer servers mean a smaller data center ftprint. That translates t direct savings n real estate, pwer, and cling. It als translates t indirect savings n business cntinuity and facilities maintenance. Even thugh these savings extend t the private clud mdel, the public clud mdel ffers small and medium- size businesses the pssibility f eliminating the need fr a data center. But as the new shift in clud cmputing expands, businesses will likely see a cmbinatin f private and public clud mdels becme the mst ppular implementatin. This cmbinatin prvides the mst flexible IT infrastructure and has cmpelling csts savings f its wn: 4. Virtualizatin Decreases IT Csts. Scaling infrastructure t meet new wrklad demands, maintaining physical security, and sftware deplyment and patching are just a few examples f cstly IT management tasks that are decreased significantly by running a virtualized infrastructure. 5. IT as a Service Decreases IT Csts. Private r hsted private cluds allw users t prvisin many IT services n their wn thrugh self- service prtals. Significant savings can result n cmmn help desk calls and ther IT management tasks like prcurement and server cnfiguratin.
