Cloud computing uses remote servers and the internet to maintain data and applications. It provides benefits like reduced costs, flexibility, and collaboration capabilities. Cloud computing delivers on-demand IT resources and applications from external providers via internet technologies in various forms including Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Cloud structures can be private, public, or hybrid depending on the needs and resources of an organization.
Cloud
- 1. Cloud Computing Cloud computing is an emerging computing technology that uses the Internet and central remote servers to maintain data and Applications´
- 2. Benefit • You don’t have to own the hardware • You don’t have to own the Software • Cost control • Agility/flexibility of technology • Real time information and immediate feedback Work Anywhere at any time Collaboration Sharing Work wherever you are
- 3. Benefits • Increase IT responsiveness and efficiency. • Reduce capital expenditures and operational overhead. • Provide greater business flexibility through an on-demand, pay-as-you-go model that scales with your business. • Get more choice in providers — use in-house or third-party vendors. • Free up IT resources for innovation
- 4. What is Cloud Computing A style of computing where massively scalable (and elastic) IT-related capabilities are provided “as a service” to external customers using Internet technologies.
- 5. DISA’s Components to Cloud Computing Platform-As-A-Service (PaaS) Infrastructure-As-A-Service (IaaS) Software-As-A-Service (SaaS)
- 6. Platform-As-A-Service (PaaS) It is a software development and hosting environment made up of development tools, databases, middleware and infrastructure software.
- 7. Infrastructure-As-A-Service (IaaS) It enables your system administrators and developers to self-provision the compute, storage and network resources they need to deploy and run applications and operating systems
- 8. Software-As-A-Service (SaaS It gives your users web access to applications hosted on a service provider's infrastructure. A wide range of applications can be delivered through a SaaS model, such as customer relationship management, collaboration, email and enterprise resource management.
- 9. Cloud Structures • Private clouds, whether operated and hosted by your enterprise IT department or by an external provider, are for the exclusive use of your organization. • Public clouds are open to any number of organizations and individual users on a shared basis. Using a public cloud minimizes your initial capital investment and combines agility and efficiency with massive scalability. • Hybrid clouds link private and public clouds, providing access to extra resources when the private cloud hits maximum utilization. Or, a hybrid cloud might split computing by tier between private and public clouds. For example, the database may reside in the private cloud while the application server is located in the public cloud.
