Department of Computing Faculty of computing and information Technology (FCIT) Indus University, Karachi SEE-321 Cloud Computing ASSIGNMENT NO 1 Basic concept of cloud computing (CLO1, C1) Name: KANZA BATOOL Students I.D: 2096-2019 Date of submission: 10TH April 9, 2022 Submitted to: MAAM RESHMA Teacher sign:__________ Q1. Explain basic characteristics of cloud? Ans.1: CHARACTERISTICS OF CLOUD: Following are the characteristics of cloud 1. Resources Pooling: Cloud provider use multi-leaner model to provide computing resources to different cloud consumers. In cloud, a consumer can use resources with other users. 2. On-Demand Self-Service: Cloud is based on self-service model where a cloud consumer can manage and monitor the computing functionalities. User can track on server uptimes, capability and network storage. 3. Easy Maintenance: Maintenance in cloud is very easy for consumers. Also, cloud come up with update time to time. 4. Large Network Access: A cloud consumer can use the cloud services from anywhere. Cloud doesn’t have any geographical boundaries. 5. Availability: Cloud can modify and extend the storage as per the consumer usage. It analyze the storage and allow user to have extra cloud storage. 6. Automatic System: Cloud automatically analyze the data and support service level measuring.it help to track, manage and report the usage. 7. Economical: It is one time investment for consumers to get resources and cloud services. Only amount is spent in modification and maintenance. 8. Security: Cloud provide the security to user and create the snapshot of data stored so that data cannot get lost. The data storage service is reliable and secure. 9. Pay as you go: In cloud, consumer only have to pay for the service or space which they need. There is no additional and hidden charges. 10. Measured Service: In cloud, services are monitor and record by the consumers. The resources are being analyzed by charge-per-use capability. Q2. Why Cloud enabled solutions are being implemented in enterprise business solutions. Also comprehend key classical data center infrastructure components. Ans.2: CLOUD COMPUTING FOR ENTERPRISE BUSSINESS: Cloud computing saves businesses time and money by boosting productivity, improving collaboration, and promoting innovation. Here are five additional benefits enterprise businesses can have from cloud computing solutions: 1. Extremely accessible data Businesses use cloud computing to access information anywhere with any compatible device. Rather than storing information on your computer or a server in your office, cloud computing stores data on the internet. Information is available from a central web-based hub that gives anyone with proper credentials access from any location with an internet connection. 2. Maintains consistency between users When multiple workers are working on the same digital file, it's easy for mistakes to happen. Since cloud-hosted files exist in the same central location, data is automatically synced between all devices, which means people are using the most up-to-date version of files. 3. Allows for remote programs Businesses rely on software that isn't commonly used at home. Since specialized software is often installed on company computers in the office, cloud computing allows users to access all types of files and applications as though they were in the office. By removing the barrier for employees to use the programs they're comfortable with, regardless of where they are physically, cloud computing brings the office to the kitchen table. 4. Easy data backup Catastrophic data loss can happen at any time. Whether that loss occurs from natural disasters, power surges, or hardware failure, affected companies are at increased risk of bankruptcy within the same year as the data loss. And while most companies have adopted backup plans, it helps to have additional contingencies in place. By utilizing the cloud to store important data, business owners can rest easy knowing that important files are safe even if hardware fails. 5. Cost-efficient Buying and maintaining server equipment requires time, expertise and money. Rather than building your own bespoke server, which can be prone to downtime, a cloud computing provider stores data for you without all the downsides. Prices for business-oriented cloud services are still a monthly expense, but it's a manageable and predictable expense in many aspects. DATA CENTER INFRASTRUCTURE COMPONENTS: The core elements of a classic data center are: 1. Compute: A core commonality of all data centers is servers. 2. Storage: Storage devices, such as hard-disk, solid-state, and robotic tape drives are important to helping any data center run these servers. 3. Network: Network infrastructure consists of hardware like routers, switches, security appliances and firewalls. 4. Application: Data centers rely on software to run it. This includes various operating systems and applications that run on their servers, 5. Database Management System (DBMS): Data center also manage the database of a consumer to keep record of data.
