Overview Of Cloud Standards

Image
Cloud computing slowly becoming reality. So it has to address many concerns such as security, interoperability, portability, and governance at the earliest opportunity. This can be accelerated by compliance to guidelines and standards defined in consensus by the cloud providers.  Without addressing these concerns, users would be wary to tread this path in spite of its powerful economic model for business computing. Interoperability/integration Interoperability enables products/software components to work with or integrate with each other seamlessly, in order to achieve the desired result. Thus, it provides flexibility and the choice to use multiple products to achieve our needs. This is enabled by either integrating through standard interfaces or by means of a broker that converts one product interface to another. Cloud computing depends on compliance standards. Security Security involves the protection of information assets through various policies, procedures, a

ITaaS is the most recent entrant to the IT landscape. It is an efficient delivery method. With the meteoric and mesmerizing rise of service orientation principles, every single IT element is being viewed and visualized as a service that sets the tone for the service era. Two top methods for Cloud integration 1 - Integration as a service (IaaS) It is a budding and distinctive capability of clouds that help in fulfilling internal as well as external business integration requirements. Increasingly, business applications are deployed in clouds to reap the manifold business and technical benefits of using clouds. On the other hand, innumerable mission-critical applications and data sources still remain locally stationed and sustained primarily due to the expressed security concerns associated with hosting them in clouds. The question here is how to create seamless data flow between hosted and on-premise applications so that they work together. The IaaS overcomes these challenge

Case Study On Cloud Computing

Image
The concept of cloud computing is in use for many years, but in recent years has it become a highlighted and come in picture. In the year 1990s, cloud computing was developed by major IT providers such as Sun, Microsoft, Google, and Amazon. Cloud computing Different products came into use for different levels of users. The most popular services for end users include web-based email systems (SaaS), e.g. AOL, Gmail, Hotmail, and Yahoo! Mail, and office applications such as Google Docs, Microsoft MS Office Online, Cloud-canvas.com, and Write.fm, etc. Developers can run their programs on the cloud (PaaS) like Google AppEngine , Windows Azure, and Force.com. Companies or organizations store or backup their large data on remote servers (IaaS), for example, Rackspace, Microsoft Azure, Animoto, Jungle Disk and Amazon's EC2 or S3 servers. In 2011, the Primary Research Group (PRG) published a report of its recently conducted survey on library use of cloud computing (Primary Resear

Cloud Computing Vs Virtualization Real Differences

Servicing of computing resources you can say as Cloud computing. They charge for some amount each service used by an user. On the other hand, making multiple machines virtually by using same hardware is called virtualization. Sell all the real differences. Public Vs Private Vs Hybrid Cloud Public Cloud:  Available to the public is called the PUBLIC cloud.  Private Cloud : Available to the particular Business/Company is called PRIVATE Cloud.  Hybrid Cloud: Combination of Public and Private Clouds. Cloud Services Related: How Industries will Change due to Cloud Computin g Cloud Services Cloud services (remote data and computation) are exposed as simple and user-friendly web services. For example, Microsoft's ADO.NET (originally called Astoria) provides the tools to expose any data object from a collection, stored in a database or other form, as a URI to an encoded form using a standard such as JSON or ATOM representation Google's AppEngine provides a way

Major Trends in IT in 2015

As per research paper submitted by Gartner, the following trends will dominate in IT industry. Advanced, Pervasive and Invisible Analytics: Analytics will take center stage as the volume of data generated by embedded systems increases and vast pools of structured and unstructured data inside and outside the enterprise are analyzed. "Every app now needs to be an analytic app," said Mr. Cearley. "Organizations need to manage how best to filter the huge amounts of data coming from the IoT, social media and wearable devices, and then deliver exactly the right information to the right person, at the right time. Analytics will become deeply, but invisibly embedded everywhere ." Big data remains an important enabler for this trend but the focus needs to shift to thinking about big questions and big answers first and big data second — the value is in the answers, not the data. Cloud/Client Computing: The convergence of cloud and mobile computing will continue
