- 4. What is Cloud? οCloud is something which is present at a remote location. οIt can be used as symbolize the Internet. Ex: As a personal or business cloud computing user, you access your stored information on the 'cloud', via an Internet connection.
- 5. What is Cloud Computing? οCloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. οClouds may be limited to a single organization (enterprise clouds), or be available to many organizations (public cloud).
- 6. Characteristics of cloud computing ο Availability The capabilities of the Cloud can be modified as per the use and can be extended a lot. It analyzes the storage usage and allows the user to buy extra Cloud storage if needed for a very small amount. οEasy Maintenance The servers are easily maintained and the downtime is very low and even in some cases, there is no downtime. Cloud Computing comes up with an update every time by gradually making it better.
- 7. Continueβ¦. οResources Pooling It means that the Cloud provider pulled the computing resources to provide services to multiple customers with the help of a multi-tenant model. There are different physical and virtual resources assigned and reassigned which depends on the demand of the customer. οRapid elasticity Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand.
- 8. Continueβ¦. ο Security The data is stored within the storage devices, which cannot be hacked and utilized by any other person. The storage service is quick and reliable.
- 9. Types of clouds οIaaS (Infrastructure-as-a-Service) οPaaS (Platform-as-a-Service) οSaaS (Software-as-a-Service)
- 10. IaaS οcloud-computing offering in which a vendor provides users access to computing resources such as servers, storage and networking. οprovides you the computing infrastructure, physical or (quite often) virtual machines and other resources Ex 1. Amazon Web Services (AWS) AWS helps companies store data and deliver content EX 2. Microsoft Azure allows for building, testing, and managing applications through a network of Microsoft data centers.
- 11. PaaS οPaaS builds on the IaaS. ο(PaaS) is a concept that describes a computing platform that is rented or delivered as an integrated solution, solution stack or service through an Internet connection. οThe PaaS service delivery model allows a customer to rent virtualized servers and associated services used to run existing applications, or to design, develop, test, deploy and host applications. Ex: AWS Elastic Beanstalk, Heroku, Windows Azure (mostly used as PaaS), Force.com, OpenShift, Apache Stratos, Magento Commerce Cloud.
- 12. SaaS οSaaS is a model for the distribution of software where customers access software over the Internet. Ex: Google Apps, Dropbox, Salesforce, Cisco WebEx, Concur, GoToMeeting
- 13. Difference β¦
- 14. Advantages of cloud computing οLower computer cost οImproved performance οReduce software costs οInstance software updates
- 15. Disadvantages of Cloud Computing οRequires a constant internet connection οStore data can be lost οStored data might not be secure οDoes not work well with low speed connection
