INTERACTIVE SESSION: ORGANIZATIONS Computing Takes Off in the Cloud Cloud computing is now the fastest-growing form o computing. The biggest players in the cloud com- puting marketplace include Amazon Web Services (AWS), Microsoft, and Google. These companies have made cloud computing an affordable and sen- sibl net startups to established companies like Netflix owning information technology, it doesn't alway deliver on its promise. For large companies a public cloud provider a monthly service fee for 10,000 or more employees may actually be expensive than having the company maintain its own IT infrastructure and staff. Companies also worry about unexpected "runaway costs" from u a pay-per-use model. Integrating cloud services with existing IT infrastructures, errors, mismanagement, or unusually high volumes of web traffic will run up f ng or example, AWS provides subscribing companies with flexible computing power and data storage as well as data management, messaging, payment, and other services that can be used together or individu ally as the business requires. Anyone with an Inter net connection and a little bit of money can harness the same computing systems that Amazon itself uses to run its retail business. If customers provide speci- fications on the amount of server space, bandwidth storage, and any other services they require, AWS can automatically allocate those resources. You don't pay a monthly or yearly fee to use Amazon's com puting resources-instead, you pay for exactly what you use. Economies of scale keep costs astonishingly low, and AWS has been able to keep reducing prices. To remain competitive, other cloud computing ven dors have had to follow suit e bill for cloud service users. The more data and tems that a company uses in the cloud, the b ger the job of changing cloud providers. When y buy cloud software, you may be stuck with it for a Gartner, Inc. technology consultants advise cli ents contemplating public cloud services to take into account the number of machines an organization will run, the number of hours per day or per week they'll run, and the amount of storage their data will require. Additional costs include licenses that need to be paid for on a recurring basis, the rate of change for the data, and how much new data the busines is expected to generate. A very large company may find it cheaper to own and manage its own data cen- ter or private cloud. But as public clouds become more efficient and secure and the technology grows Cloud computing also appeals to many busi nesses because the cloud services provider handle all of the maintenance and upkeep of their IT infrastructures, allowing these businesses to spend more time on higher-value work. Startup aper, large companies will start using more cloud che major barrier to widespread cloud adoption is concern about cloud reliability and security. Ama zon Web Services experienced an outage on Septem- ber 20, 2015, that affected Netflix, Reddit, IMDB, Product Hunt Alexa and Instant Video services for users across eastern North America. There were als Amazon cloud outages several times a year in the preceding five years. As cloud computing contin- ues to mature and the major cloud infrastructure providers gain more experience, cloud service and reliability have steadily improved. Experts recom- mend that companies for whom an outage would be a major risk consider using another computing s and smaller companies are finding that y no longer need to build their own data center. ompa With cloud infrastructures like Amazon's readily and Amazon's own sses.
