Architecting the Cloud: Design Decisions for Cloud Computing Service Models (SaaS, PaaS, and IaaS) Michael J. Kavis
Publisher: Wiley

Those are DaaS (data as a service), SaaS (software as a service), PaaS (platform as a service), and IaaS (infrastructure as a service). Private Cloud Growing 50%, Leading to Hybrid Model. On the other hand, with the latest breed of PaaS providers such as Force.com, Google App Engine, and Microsoft Windows Azure, a different type of application development model emerges and offers new possibilities. Aug 21, 2012 - Cloud computing is a model where the storage and computing capacity is provided as a service, usually on the internet, in a remote accessible fashion to heterogeneous parties. Mar 6, 2014 - Earlier this week, DZone's 2014 Cloud Platform Report further substantiated this by indicating that PaaS adoption is finally ahead of IaaS, and we offered insight into why this is happening, and specifically why now. However, the case is different for Now that IaaS providers like Amazon, Google and Microsoft have cut prices considerably, should PaaS providers trickle down the cost savings on infrastructure to PaaS customers as well? Business leaders know they must improve their ability to deliver software because, more and more, software is embedded within their business, products, and services, helping them compete. They propose cloud computing as a service model sharing a pool of configurable resources, which is a suitable workbench to address these challenges (Figure 1). Jan 10, 2014 - The above mentioned IT resources, in the form of applications (SaaS), platforms (development environments; PaaS) and infrastructures (virtual servers, storage; IaaS) are provided as services that a user can order. Let's take a look at a two decision criteria: Scenario .. May 16, 2014 - Cloud Computing · Windows · Windows Azure Hear first hand Oracle customer case studies and join in the discussion on the business and IT decisions made in selecting the right cloud infrastructure and the benefits other organisations have seen. Apr 30, 2014 - Of course some services that run on cloud infrastructure might never get price cuts, especially certain software-as-a-service (SaaS) companies that are already providing services at a very thin margin. Aug 16, 2011 - By comparing the characteristics of a solution under evaluation to the vendor-neutral NIST cloud computing model, you can validate both (1) that the solution meets the minimum standards of architecture and workflow to be called a cloud solution Regardless of the type of cloud deployment model used, a cloud solution needs to deliver value based on one of three recognized service models: Infrastructure, Platform, or Software as a Service (IaaS, PaaS, or SaaS). Mar 23, 2010 - Business Services and Software-as-a-Service (SaaS) – The traditional apps layer in the cloud includes software as a service apps, business services, and business processes on the server side. Architecting cloud solutions, designing and developing cloud projects, and delivering cloud training are his daily activities as part of driving the adoption of Cloud Computing, specifically on Windows Azure platform. Dec 16, 2011 - Cloud Computing Service Model PaaS (Platform as a Service) Paas is one level up from IaaS, where cloud providers not only take care of the components that IaaS does; but also manage the platform-level components like middleware and runtime. Bioinformatics generates An interesting approach to design of biomedical cloud system was described by Taverna [26]. The main drive to use cloud SaaS: no responsibilities,; PaaS: only responsibility for the application and the data the application uses,; IaaS: the responsibility of configuring the OS and middleware, software updates and licenses (in addition to PaaS).
