Cloud computing- Benefits,Future and Challenges

All about cloud computing

1. Why it is called so ? Metaphorically the word cloud is used because of the analogy between the property of rain clouds and the way the cloud computing is designed Benefits ! Cost Effective Easy to implement Secure and Reliable Flexible and Scalable Interoperable Cloud computing is all about accessing computing capabilities like storage, processing, security on different digital platforms from any location through internet What is cloud computing

2. Lower Upfront Costs Lower Hardware Requirements Access Anytime, Anywhere Backups and Recovery Competitiveness Document Control Security Increased Productivity

3. How Cloud Computing Works If you have experienced using e-mail, you have already experienced using the cloud. Basically, what you are loading on your machine, as an e-mail user, is simply – an application. You log in into a Web Service, and all the programs necessary to actually run the application, are located on a remote machine owned by another company. The real storage and the software does not exist on your computer, but exist instead – on the cloud. It is estimated that there is over 1 Exabyte of data stored in the cloud at the moment, or 1,073,741,824 gigabytes of data. The Gartner prediction is that at the year-end 2016, more than 50% of Global 1000 companies will have stored customer-sensitive data in the public cloud. By adopting the cloud, companies are relying on an automated decision making system to reduce the number of the staff they need to perform complex calculations, analysis, and to actually maintain the system.

4. What is Cloud Made of? Cloud can be divided broadly into two layer – front end and back end On front end we have a client , an application, user interface On the back end of the system, there are: Computers that run the applications Servers (with a central server(s)) Data storage systems

5. Types of Cloud Computing Based on a deployment model Public Private Hybrid Hommunity cloud Based on a service : IaaS (Infrastructure-as-a-Service) PaaS (Platform-as-a-Service) SaaS (Software-as-a-Service)

6. Based on Deployment Model Public Cloud: The whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. The location remains, thus, separate from the customer and he has no physical control over the infrastructure. As public clouds use shared resources, they do excel mostly in performance, but are also most vulnerable to various attacks. Private Cloud: Provides the same benefits of Public Cloud, but uses dedicated, private hardware. Private cloud means using a cloud infrastructure (network) solely by one customer/organization It is not shared with others, yet it is remotely located The companies have an option of choosing an on premise private cloud as well, which is more expensive, but they do have a physical control over the infrastructure.

7. Continued… Hybrid Cloud: Means, using both private and public clouds, depending on their purpose. For example, public cloud can be used to interact with customers, while keeping their data secured through a private cloud. Community Cloud: Implies an infrastructure that is shared between organizations, usually with the shared data and data management concerns. For example, a community cloud can belong to a government of a single country.

10. SWOT Analysis of Cloud Computing

11. Challenges Cloud Computing is Facing Lack of Resource and Expertise -Organizations are increasingly placing  more workloads in the cloud while cloud technologies continue to rapidly advance. Due to these factors organizations are having a hard time keeping up with the tools. Security - Security has indeed been a primary, and valid, concern from the start of cloud computing technology: you are unable to see the exact location where your data is stored or being processed which leads to data breaches, compromised credentials and broken authentication, hacked interfaces and APIs.

12. Challenges Cloud Computing is Facing Performance Dependency -When a business moves to the cloud it becomes dependent on the service providers. On the other hand the performance of the organization’s BI and other cloud based systems is also tied to the performance of the cloud provider when it falters. Segmented usage and adoption - Most organizations did not have a robust cloud adoption strategy in place.  One of them was the speed of cloud adoption. Another one was the staggered expiration of data center contracts/equipment, which led to intermittent cloud migration.  Cost - Cloud computing itself is affordable, but tuning the platform according to the company’s needs can be expensive. Furthermore, the expense of transferring the data to public clouds can prove to be a problem for short-lived and small-scale projects.

13. Is there a Future? Internet speed available to the general consumers is increasing at a huge speed Start-ups on everything—from grocery to mattress---will have to depend on the cloud infrastructures People have a lot to gain ---from the consumers getting discount, to the entrepreneurs saving infrastructure costs and the service providers getting a steady platform fee Cloud computing thus have a very bright future At the end of 2015, 88% entrepreneurs shifted their business to cloud By 2020, most of the non-cloud companies are going to implement some cloud services in their work As storage and low-power processor costs plummet, hosting a server firm will become more lucrative

14. What is the Future? Artificial Intelligence: Where processing power is abundant, AI learns quickly. Thus most recent AI s are cloud based Internet of Everything: As each and every device starts interacting with each other, this horde of data will be needed to be stored and processed and cloud computing provides the cheapest and fastest alternative Blockchain: Though bitcoin prices have fallen drastically, block chain technology has the ability from keeping health records to tracing diamonds from mines to customers ---all on cloud computing support Autonomous vehicles: The backbone of the driverless cars---its software updates and machine learning are all situated in the cloud
