Cloud Computing ist im Grunde die Bereitstellung von Computingressourcen (z.B. The concept of Cloud Computing came into existence in 1950 with implementation of mainframe computers, accessible via thin/static clients. Cloud computing is an evolution in which IT consumption and delivery are made available in a self-service way via the Internet or internal network with a flexible, pay-as-you-go business model that runs on a highly efficient and scalable architecture. Provide a RESTful interface that allows clients to discover the set of resources it exposes according to the OCCI HTTP rendering model.

How Cloud Computing will Transform Insurance Using Cloud to help drive future high performance in the insurance industry An Accenture point of view. C1HAPTER. It also allows for real-time collaboration so you don’t have 100 versions of the same file floating around. Figure 11.8 provides a reference scenario for the Open Cloud Computing Interface, which defines a single access point to the resources managed by a given cloud resource provider. We analyzed each issue with details and discussed the possible solutions based on existing techniques. The company reduced costs by $90 million at the two-year mark and is on track to cut another $60 million. ��������A��2A�2:H��U��w�H�� �k��� ;�:��7����c�� 9V���!l�Sx����4l&���ى���$�f`�� With cloud computing, businesses access applications via the internet. One copy is a whole lot easier to control. Cloud computing can also offer pre-built solutions and services, backed by the skills necessary to run and maintain them, potentially lowering risk and removing the need for the organization to retain a group of scarce highly-skilled staff. Common resources in this scenario are Compute, Storage, and Network. Cloud computing: The very definition of cloud computing remains controversial. Cloud computing has been around for approximately two decades and despite the data pointing to the business efficiencies, cost-benefits, and competitive advantages it holds, a large portion of the business community continues to operate without it. The cloud is the foundational enabler of digital transformation projects and offers the scale and speed that is needed for businesses to focus on transformation; with a clear impact on the role of the IT department. Cloud computing serves different needs for different constituents within your organization. l Cloud computing does not exist in a vacuum. What are the key value propositions of cloud computing? A Brief History of Cloud Computing. The cloud delivers benefits to both the business, through enablement, and IT via operational improvements. It takes a bird's-eye view of the sweeping changes that cloud computing is bringing about. It is a new platform which created a global footprint with over 1500 CDN Nodes worldwide of 19 regions and 56 availability zones across more than 200 countries. For your IT organization, the cloud is a platform that allows it to be significantly more These specifications define protocols and APIs for several kinds of management tasks. It’s called Software As A Service (or SaaS). endstream endobj startxref Cloud Computing Many companies are delivering services from the cloud. Is NIST’s cloud definition comprehensive? Astonishing Cloud Computing Statistics For 2020 (Editor’s Choice): The global public cloud computing market is set to exceed $330 billion in 2020. What is the best way to describe the cloud? This chapter provides a general overview of cloud computing, and the technological and business factors that have given rise to its evolution. Rather than offering a complete definition and/or solution for this challenging issue, this chapter aims at providing a reference for practical deployment and further research on this topic. Financial institutions use private cloud computing environments, 5. public cloud computing environments, 6. or a hybrid of the two. Cloud computing is an important answer to the issue of data-loss and recovery on physical hard drives. In this chapter, we discussed the basic concepts behind the cloud and introduced the security issues underlying cloud computing. Automation also significantly improved performance and agility.
