Cloud Computing Secondary 1 – #2Storage Devices Information Communication Technology Client Server Network Server is the powerful computer that receives and responds to request for services and data from multiple clients The individual users are called clients The type of network with at least one server is called the client server network 2 Information Communication Technology Cloud Computing (Storage) A method of data storage where data is stored on remote servers There may be thousands of servers in many different locations The same data is stored on more than one server allowing clients to access data at any time This is known as data redundancy 3 Information Communication Technology Advantages of cloud computing Client files stored in the cloud can be accessed at any time, from any device, anywhere in the world No need for a user to carry an external storage device Provides the user with remote backup of data The cloud system offers almost unlimited storage capacity 4 Information Communication Technology Disadvantages of cloud computing Clients cannot access data without the internet connection Costs can be high if a large storage capacity or high download/upload data transfer is required The potential failure of the cloud storage company is always possible Potential security risks 5 Information Communication Technology Three types of cloud storage systems 6 Information Communication Technology Public cloud This is a storage environment where the client and cloud storage provider are different companies / organizations Multiple clients may use the same cloud. 7 Information Communication Technology Private cloud This is storage provided by a dedicated server of a company / organization Client and cloud storage provider are single entity. However, the server may exist at a remote location 8 Information Communication Technology 9 Information Communication Technology Hybrid cloud Combination of the two previous environments Some data will be stored in the private cloud Less sensitive data will be stored in the public cloud 10 Information Communication Technology Any questions? 11 Information Communication Technology
