Cloud Solutions
A cloud service is any service made available to users on demand via the Internet from a cloud computing provider's servers as opposed to being provided from a company's own on premises servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider.
A cloud service can dynamically scale to meet the needs of its users, and because the service provider supplies the hardware and software necessary for the service, there’s no need for a company to provision or deploy its own resources or allocate IT staff to manage the service. Examples of cloud services include online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services and more.

Here are some types of cloud solutions:
​
INFRASTRUCTURE AS A SERVICE (IaaS)
IaaS is a standardized, highly automated offering, where compute resources, complemented by storage and networking capabilities are owned and hosted by a service provider and offered to customers on-demand. Customers are able to self-provision this infrastructure, using a Web-based graphical user interface that serves as an IT operations management console for the overall environment. API access to the infrastructure may also be offered as an option.
​
PLATFORM AS A SERVICE (PaaS)
​
PaaS offerings facilitate the deployment of applications or services without the of buying and managing the underlying hardware and software and provisioning hosting capabilities. All "as-a-service" offerings are characterized as providing low initial cost, incremental cost as your service usage grows, self-service, best practices built-in, resource sharing, automated deployment, management services, lifecycle management, reuse. PaaS provides these capabilities for application and service development.
​
SOFTWARE AS A SERVICE (SaaS)
​
SaaS is typically accessed by users using a thin client via a web browser. SaaS has become a common delivery model for many business applications, including office & messaging software, DBMS software, management software, CAD software, dDevelopment software, virtualization, accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), content management (CM) and service desk management.
​
DESKTOP AS A SERVICE (DaaS)
