Feb 17, 2011 - The confusion over cloud service model definitions continues to be driven by the pace of evolution in the market, according to Darryl Humphrey, senior manager leading the Canadian cloud practice at Deloitte & Touche LLP. That's my inescapable observation based on all the architecture profiles I've written on HighScalability.com. Dec 3, 2013 - Infrastructure as a Service (IaaS), Platform as a Service (PaaS ) and Software as a Service (SaaS) are the terms used in describing the architecture while private cloud, public cloud, hosted cloud, government cloud and a few other variations of The role abstractions encapsulate a programming model and a deployment model aided by a resource descriptor which when combined provides complete metadata for design time deployment as well as run time operations. Apr 4, 2012 - In very simple terms, cloud computing is a new consumption and delivery model for information technology (IT) and business services that is characterized by: Can use clouds for nearly everything: SaaS, IaaS, collaboration services, online presence . 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. Apr 12, 2012 - Definition of a single Cloud Computing Reference Architecture, enabling cloud-scale economics in delivering cloud services while optimizing resource and labor utilization and delivering a design blueprint for .. Rather than simply delivering prepackaged applications via the on a service model, a PaaS provider offers up the entire computing platform and solutions stack needed for an application runtime environment. Apr 28, 2014 - Review Architecting the Cloud: Design Decisions for Cloud Computing Service Models (SaaS, PaaS, and IaaS) Great Product An expert guide to selecting the right. Mar 26, 2012 - Cloud technology is a natural extension of commoditizing IT and that advances in network infrastructuremaking internet access cheaper & faster directly facilitated offloading computing (hardware, software/services) to the cloud. Let's take a look at a two decision criteria: Scenario .. €�A must-read for anyone involved in cloud design and decision making! May 20, 2013 - In Cloud Computing: Concepts, Technology & Architecture, Thomas Erl, one of the world's top-selling IT authors, teams up with cloud computing experts and researchers to break down proven and mature cloud computing Also provided are templates and formulas for calculating SLA-related quality-of-service values and numerous explorations of the SaaS, PaaS, and IaaS delivery models. So we'll just skip all the old arguments about OpEx vs CapEx, IaaS vs PaaS vs SaaS, virtualization vs bare metal, public vs private vs hybrid clouds, and open vs closed clouds. But yes, many of them, especially the large one will continue to rely on their application and infrastructure teams in-house, supported by cloud models. 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. Feb 26, 2014 - In my opinion the popular SPI-model of the cloud landscape, which divides it into Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS), is simplifying reality way too much. Jan 2, 2013 - As the market for cloud services expands, the providers at each level of the stack are realizing various opportunities beyond their core solutions. Moreover, be it public or private PaaS some fear of lock-in will always persist and that is where the design and architecture competence comes into play. Based on those, the value proposition will guide the adoption plan for cloud ; the profit proposition will do detail cost benefit analysis for the specific situations/scenarios of the organization on use of SaaS, PaaS or IaaS. I hope to show, using many real examples from real startups, that the cloud is built on a powerful system of ideas and technologies that make it a superior model for delivering IT.
