- 3. The cloud refers to application, services and data storage on the internet. “Cloud Computing” simply means the use of computing resources as a service through internet. With this, users can access database resources via internet from anywhere, for as long as they need, without worrying about any maintenance or management of actual resources.
- 4. Cloud computing is both, combination of software and hardware based computing resources delivered as a networked service. These applications and resources can be accessed using a simple front end interface such as web- browser. Thus enabling users to access resources from any client device including notebooks, desktops and mobile devices.
- 5. Characteristics of cloud computing:
- 7. Cloud architecture is the way technology components combine to build a cloud, in which resources are pooled through virtualization technology and shared across a network.
- 8. The cloud computing architecture comprises two fundamental components, i.e. frontend and backend. Frontend works as a client in such architecture and communicates with the backend via a network or internet. In the cloud computing architecture, the client-side or frontend is visible to the end-user. The frontend sends queries to the backend via the middleware. The backend protects the data and respond to the queries asked by the frontend. The backend is a bigger part of the whole cloud computing architecture as shown:
- 10. There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models of cloud computing: 1. Deployment Models 2. Service Models
- 11. Deployment models define the type of access to the cloud, i.e how the cloud is located? Cloud can have any of the four types of access: 1. Public 2. Private 3. Hybrid 4. Community
- 13. • Allows system and services to be easily accessible to general public. • It may be less secure because of itf openness, eg., e-mail. Public • Allows systems and services to be accessible exclusively for organization’s benefit. • Offers increased security because of its private nature. Private
- 14. • Mixture of public and private cloud. • However, the critical activities are performed using private cloud and non critical activities, using public cloud. Hybrid • Allows systems and services to be accessible by group of organizations. • It may be owned ,managed and operated by one or more org. in the community. Community
- 19. The three Cloud Service Models are as follows: 1. Infrastructure as a Service (IaaS) 2. Platform as a Service (PaaS) 3. Software as a Service (SaaS)
- 21. Do you use cloud??
- 23. Cloud storage is a cloud computing model that enables storing data and files on the internet through a cloud computing provider that you access either through the public internet or a dedicated private network connection. The provider securely stores, manages, and maintains the storage servers, infrastructure, and network to ensure you have access to the data when you need it at virtually unlimited scale, and with elastic capacity. Cloud storage removes the need to buy and manage your own data storage infrastructure, giving you agility, scalability, and durability, with any time, anywhere data access.
- 24. Cloud storage is delivered by a cloud services provider that owns and operates data storage capacity by maintaining large datacenters in multiple locations around the world. Cloud storage providers manage capacity, security, and durability to make data accessible to your applications over the internet in a pay-as-you-go model. Typically, you connect to the storage cloud either through the internet or through a dedicated private connection, using a web portal, website, or a mobile app. When customers purchase cloud storage from a service provider, they turn over most aspects of the data storage to the vendor, including capacity, security, data availability, storage servers and computing resources, and network data delivery.
- 25. Cloud Storage • Create an Account User name and password. • Content lives with the account in the cloud. • Log onto any computer with Wi-Fi to find your content.
- 26. Download a cloud based app to on your computer. The app lives on your computer. Saves files to the app. When connected to internet it will sync with the cloud. The cloud can be accessed from any Internet Connection.
- 27. There are three main cloud storage types: 1. Object storage, 2. File storage, 3. Block storage. Each offers its own advantages and has it own use cases.
