16 Cloud services Presented by IBM developerworks There are four basic things people are doing in the cloud: Machines in the cloud Storage in the cloud Databases in the cloud Applications in the cloud In addition to these four basics, cloud providers offer other services such as message queues and data mining All of these things are lumped into the generic term cloud computing 16 An Introduction to Cloud Computing 2009 IBM Corporation

17 Machines in the cloud Many cloud providers allow you to create a Virtual Machine (VM) and deploy it in the cloud Your VM images are stored in cloud storage You can create as many images as you need You can automatically start and stop running instances of those images as needed This is the simplest way to get started in the cloud, particularly if you ve been using virtualization already 17 An Introduction to Cloud Computing 2009 IBM Corporation

18 Storage in the cloud Most cloud storage systems are designed as distributed, redundant systems Your data are stored on more than one disk in more than one place If one part of the system goes down, the rest of the system keeps going There should never be a single point of failure is a stated design goal But you can t think of cloud storage as just another hard drive 18 An Introduction to Cloud Computing 2009 IBM Corporation

19 Databases in the cloud Cloud databases have similar design points Datasets are distributed for reliability Some cloud databases support schemas, some don t Some cloud databases support joins, most don t Some cloud databases are relational, almost all aren t Some cloud databases are transactional, some aren t 19 An Introduction to Cloud Computing 2009 IBM Corporation

20 Other services in the cloud A number of vendors provide message queuing services in the cloud Some queuing services don t let you peek a message, for example Cloud data mining services use techniques such as Hadoop / MapReduce to analyze massive data sets Techniques that required supercomputers, large data centers and significant funds a few years ago can now be done for a few hundred pounds New businesses and business models will emerge based on the cost of data mining being reduced by several orders of magnitude 20 An Introduction to Cloud Computing 2009 IBM Corporation

33 Issues with the Internet It s not secure. I don t want to lose control of my infrastructure. I don t know how reliable it is. I don t know if my partners are going to use it. All of these were important, legitimate issues With VPNs and other technology, the industry solved these problems 33 An Introduction to Cloud Computing 2009 IBM Corporation

34 Issues with the cloud It s not secure. I don t want to lose control of my infrastructure. I don t know how reliable it is. I don t know if my partners are going to use it. All of these are important, legitimate issues We ve got some work to do, but the massive economic incentives mean someone will find a way to solve these problems 34 An Introduction to Cloud Computing 2009 IBM Corporation

35 Key questions to ask Will cloud computing help create and deliver innovative business and consumer services to achieve greater competitive differentiation?
