The best cloud computing services offer the opportunity for businesses to undergo digital transformation in order to improve efficiency and reduce costs. Microsoft Azure. Amazon Web Services. Google Cloud. IBM Cloud. Oracle Cloud Infrastructure. Cloud services have revolutionized computing, not least through IaaS , PaaS , and especially SaaS , which have allowed businesses to develop virtualized IT infrastructure and deliver software through the cloud, independent of a user's operating system. Even better still, businesses can also mix and match cloud services from different providers through cloud brokers in order to ensure these services work to maximum efficiency and cost effectiveness, but also to reduce the chances of vendor lock-in while also improving redundancy.
Top benefits of cloud computing
Cloud computing  is the on-demand availability of computer system resources , especially data storage cloud storage and computing power , without direct active management by the user. If the connection to the user is relatively close, it may be designated an edge server. Clouds may be limited to a single organization enterprise clouds   , or be available to multiple organizations public cloud. Cloud computing relies on sharing of resources to achieve coherence and economies of scale. Advocates of public and hybrid clouds note that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand,    providing the burst computing capability: high computing power at certain periods of peak demand. Cloud providers typically use a "pay-as-you-go" model, which can lead to unexpected operating expenses if administrators are not familiarized with cloud-pricing models.
At E3 last week, in a behind closed doors presentation called Xbox , Microsoft engineering manager Jeff Henshaw - not a member of the PR team, he points out - tells a small gathering of journalists that Xbox One's , server cloud gives the next-generation console a unique advantage. It's a somewhat abstract claim that Microsoft made first only a few weeks earlier during its Xbox One reveal event, and it's been dismissed by more than a few developers, including The Witness creator Jonathan Blow, as little more than a marketing trick. Digital Foundry's In Theory analysis concluded: "Microsoft needs to prove its position with strong ideas and practical demonstrations.
The Wolfram Language is deeply integrated with the cloud, providing seamless persistent storage of code and data, cloud computation, and instant external deployment through active documents, APIs, forms, apps, etc. CloudObject — a handle to an expression or other content in the cloud. CloudGet — get an expression from the cloud. CloudPut — put an expression into the cloud, creating a new cloud object if necessary. CloudSave — save definitions associated with a symbol to the cloud. CloudExpression — an expression whose parts can be manipulated directly in the cloud. CloudSymbol — a symbol whose value is stored in the cloud. CloudEvaluate — evaluate an expression in the cloud. CloudFunction — a pure function to be evaluated in the cloud. CloudSubmit — submit an expression for asynchronous evaluation in the cloud.
