  3. 3. What is Cloud Computing? Cloud computing: –Internet-based computing in which large groups of remote servers are networked so as to allow sharing of data-processing tasks, centralized data storage, and online access to computer services or resources. –Any computer related task that is done entirely on the Internet.
  4. 4. Cont.. ● Allows users to deal with the software without having the hardware. ● Everything is done by remote, nothing is saved locally.

  7. 7. Cont..  Simply , cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.  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.

  13. 13. Top benefits of cloud computing 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:  Cost  Speed  Global Scale  Productivity  Performance  Reliability  Security COET, Dilla University 13
  14. 14. Cont.. Cost 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. Speed 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. Global scale The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources— for example, more or less computing power, storage, bandwidth—right when they’re needed, and from the right geographic location. COET, Dilla University 14
  15. 15. Cont.. Productivity • On-site datacenters typically require a lot of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. • Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals. Performance • The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. • This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale. COET, Dilla University 15
  16. 16. Cont.. Reliability Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network. Security Many cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats. COET, Dilla University 16
  17. 17. Types of cloud computing COET, Dilla University 17
  18. 18. Types of cloud computing • Not all clouds are the same and not one type of cloud computing is right for everyone. • Several different models, types, and services have evolved to help offer the right solution for your needs. • First, you need to determine the type of cloud deployment, or cloud computing architecture, that your cloud services will be implemented on. There are four different ways to deploy cloud services:  Public cloud  Private cloud  Hybrid cloud  Community Cloud COET, Dilla University 18

  23. 23. Public cloud • Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources, like servers and storage, over the Internet. • Microsoft Azure is an example of a public cloud. • With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. • You access these services and manage your account using a web browser.

  25. 25. Private cloud • A private cloud refers to cloud computing resources used exclusively by a single business or organization. • A private cloud can be physically located on the company’s on-site datacenter. • Some companies also pay third-party service providers to host their private cloud. • A private cloud is one in which the services and infrastructure are maintained on a private network.

  27. 27. Hybrid cloud • Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. • By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options, and helps optimize your existing infrastructure, security, and compliance.

  29. 29. Community Cloud A Community Cloud is a Cloud infrastructure that is shared by users of the same industry or by those who have common goals. This Cloud infrastructure is built after understanding the computing needs of a community as there are many factors including compliances and security policies which need to be included in the community Cloud infrastructure. Ex: U.S.-based dedicated IBM SoftLayer cloud for federal agencies.

  31. 31. Types of cloud services Most cloud computing services fall into three broad categories: o Infrastructure as a service (IaaS), o Platform as a service (PaaS), o Software as a service (SaaS). • These are sometimes called the cloud computing "stack" because they build on top of one another. • Knowing what they are and how they’re different makes it easier to accomplish your business goals.

  35. 35. Infrastructure as a service (IaaS)  The most basic category of cloud computing services.  With IaaS, you rent IT infrastructure— servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. COET, Dilla University 35

  37. 37. Platform as a service (PaaS) • Platform as a service refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. • PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.

  39. 39. Software as a service (SaaS) • Software as a service is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. • With SaaS, cloud providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching. • Users connect to the application over the Internet, usually with a web browser on their phone, tablet, or PC.
