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.
The Key Differences Between On-Premise, SaaS, PaaS, IaaS
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.
Types of cloud computing
Nothing demonstrates the importance of technology in the commercial world better than the fact a system originally designed for business purposes is now widely used by consumers across the globe. From iCloud to Dropbox, Gmail to Skydrive, cloud computing is everywhere. Given its ubiquitous presence in modern life, it's perhaps a little strange to consider "the cloud" as a business tool, but for investment banks like Goldman Sachs that's exactly what it is. While the "public cloud" may be a great place to store your photos, music and documents, Goldman Sachs requires a greater deal of control over how its data is stored. Technology teams at Goldman Sachs have been providing virtual desktops and server infrastructure as a service for a while now. They just didn't call it the cloud.
You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change. Cloud computing is a big shift from the traditional way businesses think about IT resources. Here are seven common reasons organizations are turning to cloud computing services:. Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure. It adds up fast. Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning. The benefits of cloud computing services include the ability to scale elastically. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.
