What is the best Cloud provider || Different Cloud Vendors ||

Cloud service providers (CSP) are companies that offers network services, infrastructure, or business applications in the cloud. The cloud services are hosted in a data center than can be accessed by companies or individuals using network connectivity. The large benefit of using a cloud service provider comes in efficiency and economies of scale. Rather than individuals and companies building their own infrastructure to support internal services and applications, the services can be purchased from the CSP, which provide the services to many customers from a shared infrastructure. There are several different forms of services that can be used “in the cloud” by CSPs, including software, often referred to as Software as a Service (SaaS), a computing platform for developing or hosting applications, known as Platform as a Service (PaaS); or an entire networking or computing infrastructure, known as Infrastructure as a Service (IaaS). The divisions, however, are not always clear-cut, as many providers may offer multiple flavors of cloud services, include traditional web or application hosting providers. For example, you might go to a cloud provider, such as Rackspace, who started as a web hosting company and buy either PAAS or IAAS services. Many cloud providers are focusing on specific verticals, such as hosting healthcare applications in a secure IAAS environment.

Amazon and Rackspace Several large cloud initiatives helped draw attention to the CSP in the mid-to-late 2000s. Amazon helped popularize the idea of cloud services with Amazon Web Services (AWS), which provides its IAAS service for web hosting and applications to millions of customer. Amazon originally developed AWS as a way to leverage the significant infrastructure it had built up for its own e-Commerce services. In addition, several software companies such as Salesforce.com and NetSuite, built their own enterprise software services in the cloud, creating the market for SAAS. Hosting providers such as Terremark and Rackspace offered web hosting and other hosted business services for IAAS Other major cloud service providers include Cisco, Citrix, Google, IBM (SoftLayer), Oracle, Microsoft (Azure), and SAP, Rackspace, and Verizon (which acquired Terremark). Apple and Salesforce are also big players in cloud services, though they are mostly focused on delivering their own applications rather than hosting applications for others. ... https://www.youtube.com/watch?v=-OoxoSeZFbw
