Pranav Vashistha presented on cloud computing. He discussed basic concepts like traditional on-premise computing versus cloud computing. He covered first movers in cloud like Amazon, Google, and Microsoft. Pranav defined cloud computing and explained its components including clients, data centers, distributed servers. He described the three main cloud service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Pranav also covered types of cloud, benefits like scalability and cost savings, and applications like storage and databases.

- 5. Traditional Approach Few years ago- • The user used to back up their data on storage disks. With few advancements in technology, smart & handy devices are created to store data on the go. • To set-up a business successfully, you needed to invest on setting up devices, technical staff, software & licenses. As your business grows you need additional investments not only for keep your business running but also for persisting changes in technology. • You need upgrades, renewal of licenses, additional staff for managing the excessive amount of data.

- 7. Definition Cloud Computing can be defined as a technique which enables the web hosting service providers to provide their customer an efficient self-service approach. It integrates various applications, platforms, infrastructures & services which can be shared by several people or businesses at the same time. It is a blend of communication networks, business applications & IT resources which is basically implemented to cut off costs ,optimization & synchronization of various resources. Cloud Computing 7
- 8. Components of Cloud [3] Internet Clients Computers Distributed Servers Datacenter Cloud Computing 8
- 9. 1. Clients • Mobile- Mobile devices like PDAs, Smart-Phones. • Thin- Devices not having internal hard drives. • Thick- Regular computer accessing through web browsers. 2. Datacenter • It is the collection of servers where the application we subscribe are housed. 3. Distributed Servers • Servers are placed at different geographical locations to ensure that in case of a failure, the service can be accessed from some other site. Grid Computing is often confused with Cloud Computing, but they are quite different. In grid computing, a large project is divided among multiple computers to make use of their resources. Cloud computing just does opposite. It allows multiple smaller applications to run at the same time. Cloud Computing 9
- 10. Cloud’s Service Models [1] The services of a cloud includes the following traits:- • Multitenancy • Device Independency • Large Scalability • Low barriers to entry. It includes the following three models of services:- 1. Software as a Service (SaaS) 2. Platform as a Service (PaaS) 3. Infrastructure as a Service (IaaS) Cloud Computing 10
- 11. Software as a Service (SaaS) Cloud Computing 11 In this model an application is hosted as a service to customer who access it via the Internet. The idea is that you use the software out of the box as is & do not need to make a lot of changes or require integration to others systems, The provider does all the patching & upgrades as well as keeping the infrastructure running.

- 12. Cloud Computing 12 Platform as a Service (PaaS) PaaS supplies all the resources required to build applications & services completely from the internet, without having to download or install software. It is also known as “Cloudware”. PaaS services include:- • Application Design • Development • Testing • Deployment • Hosting • Database Integration • Security • Versioning
- 13. 13 Cloud Computing Infrastructure as a Service (IaaS) It offers the hardware so that your organization can put whatever they want onto it. Rather than purchase servers, software, racks, & having to pay for the datacenter space for them, the service provider rents those resources. IaaS allows you to “rent” such resources as:- • Server Space • Network equipment • Memory • CPU cycles • Storage space
- 14. 14 Cloud Computing Types of Cloud The cloud computing services can be public or private. A public cloud sells services to anyone on the internet. A private cloud is a proprietary network. It is also a data center that provides hosted services to a limited number of people. When public cloud resources are used by a service provider to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy admittance to computing resources and IT services. Services can be anything from Web-based email to inventory control, and database processing. Because the service provider controls both the applications and the data, the user can use the service from anywhere freely.
