  1. ServiceNow - Cloud Services Types of deployment models The types of deployment models: Public cloud This type of cloud is freely available for community use. It are often owned by big companies or government organisations providing freed from cost services. for instance - Gmail, Dropbox, Microsoft Azure, etc. Private cloud Private cloud is employed exclusively by one organisation for his or her internal purposes. they're generally, amid firewalls restricting the overall public from using the cloud. for instance , an enormous MNC operating private cloud for its multiple subsidiaries or business unit for his or her internal computing/sharing resources.

  2. Community cloud It is a model between public and personal cloud. Only selected organisations or communities of users having an equivalent line of business or same agenda have access to the present sort of cloud. for instance , all the banks maintaining a standard cloud having the database of loan defaulters, which is shared among the banks to refer while issuing a fresh loan. Hybrid cloud This type of cloud infrastructure may be a mixture of any of the deployment models discussed above (Public, Private and Community). for instance , an outsized company maintaining a hybrid cloud of public and personal . All the sensitive information of the businesses like future strategies, internal policies, etc. are stored and processed privately cloud while public information like product details, prices, orders are processed and stored during a public cloud. Cloud Service Models There also are cloud service models, which are categorised supported the services offered by the cloud service providers. we've discussed the three service models of cloud below − Infrastructure as a service (IaaS) This is the foremost fundamental level of cloud service, where in customer only takes computing resources or virtual hardware like storage, CPU, RAM, etc. from the cloud service providers. The customer takes complete ownership of managing applications, OS s, software, databases, etc. within the cloud. for instance − Rackspace, Digital ocean, etc. Platform as a service (PaaS) This is one level further to IaaS. Here, along side the computing resources/virtual hardware, operating system, some software service and tools also are provided by the cloud service providers. The client takes ownership of increasing appliance

  3. using those software services/tools and maintaining it. for instance − Google App Engine, Apache Stratos, ServiceNow, etc. Software as a service (SaaS) This service model offers fully functional, able to use software over the web . The service provider takes the entire ownership of managing the software, servers, database, infrastructure, etc. The SaaS services are often free or available at monthly/yearly prices. For example: Salesforce, Google Apps, ServiceNow, etc.
