Cloud computing applications often need to have a 99.999% uptime as customers use them directly over the Internet, and there is little chance of solving problems from a remote location (McAfee, 2011). As a result, databases used in cloud computing must have a very high level of reliability and be capable of managing small errors that would cause other databases to stop working or need to be rebooted. The requirement from cloud computing users for databases to be able to manage these higher levels of reliability is leading to a completely different level of research and development today (Limbasan, Rusu, 2011). Taking into account all of these factors it is clear that cloud computing is having a very disruptive effect on database research, development and use today. Cloud computing is forcing many enterprise software vendors who create databases to focus more on how their applications can be used as more than just an application. Today databases need to increasingly be used as a platform for development.
Assessing the Impact of Cloud Computing on Database Technologies
The rapid level of innovation and new product development by database software vendors to make their software applications more usable in cloud computing is also forcing a major change in how businesses uses these technologies as well. Larger businesses, often called enterprises, are using cloud computing databases to create their own internal or private cloud computing networks (Upson, 2011). This is having a major disruptive effect on how enterprises buy and pay for databases under maintenance contract agreements with the largest software companies including IBM, Microsoft, Oracle and others (McAfee, 2011). Private cloud computing systems drastically reduce the cost of owning databases, and using a concept of virtualization, or the spare processing power in their servers, companies are able to save literally millions of dollars in costs (Limbasan, Rusu, 2011). The reduction in costs is very significant as a result. The benefits include much greater control over the administration of these private cloud sites suing databases that are much easier to maintain and secure, while also gaining experience in managing public clouds, or databases that their customers and members of their supply chain will use (McAfee, 2011).
IT Infrastructure Changes
Skills Required
The basic skills required for any business to begin using databases for cloud computing include expertise with VMWare and virtualization technologies (Upson, 2011). Knowedlge of how Platform-as-a-Service (PaaS), Infrastructure-as-a-Service (IaaS) and Software-as-a-Service (SaaS) all work together, and expertise in XML programming (Chisholm, 2009). Additional skills include SQL programming, and the ability to rebuild entire servers and systems from the operating system level up.
Glossary
The following are key terms and concepts regarding the use of databases for cloud computing:
Software-as-a-Service (SaaS) -- An approach to delivering applications based on a web-based architecture, allowing many different users to interact with and use an application hosted on a server and database over the Internet (Upson, 2011).
Virtualization - The series of technologies that cloud computing platform providers including Amazon Web Services provide to create a virtual server so companies can host their applications there. Virtualization creates a server through software, allowing customers to load and use their applications there (Upson, 2011).
XML -- The acronym used to define Extensible Markup Language (XML), this is a set of rules for encoding documents in machine-readable form.

Cloud Computing Security Pros & Cons Over the last ten years, cloud computing has rapidly grown and it is expected to grow even further as more businesses move online. When cloud computing was first conceived, many skeptics dismissed it as being just another tech fad that will quickly disappear. However, over the last three years cloud computing has truly changed the way we think about IT nowadays. The Cloud has significantly
Cloud Computing as an Enterprise Application Service Reordering the economics of software, cloud computing is alleviating many of the capital expenses (CAPEX), inflexibility of previous-generation software platforms, and inability of on-premise applications to be customized on an ongoing basis to evolving customer needs. These are the three top factors of many that are driving the adoption of cloud computing technologies in enterprises today. Implicit in the entire series of critical success
Cloud Computing Many businesses are experimenting and slowly embracing the concept of cloud computing and Web2.0 .organizations choosing projects which can reap full benefits from cloud computing and Web2.0.this evolution has began as organizations are now taking a crawl, walk run approach which is building towards an eventual implementation of cloud and Web2.0 implementation. Organizations are now following the pragmatic path towards cloud computing and Web2.0 through the adoption of new
Cloud Computing Today's and tomorrow's technologies and their impact on society has been brought by the development of a new technology which is referred as cloud computing. Cloud computing are techniques and common technologies that are used in Information Technology. It means data which are hosted in a given area (center) then it is dismissed without knowing the design of hosting known as utility computing which tends to permits near real
The financial implications of having greater agility and flexibility in defining workflows has been quantified through empirical study, showing the aggregate effects on financial performance (Lin, 2010). In order for this objective to be accomplished, a series of financial metrics will be defined, and during the benchmarking period in the first objective, they will be measured. The impact of streamlining CRM processes and workflows, in addition to making quoting,
It's a tidal wave that's going to engulf us all within the next five years. Cloud services will be a $160 billion industry by the end of 2011" (Ginovsky 2011, 21). Although the decision to transition from a traditional approach to cloud computing will depend on each organization's unique circumstances, a number of general benefits have been cited for those companies that have made the partial or complete transition to
