But with the multitude of technologies out in the market, how to make a decision on which to use and when? 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. Feb 1, 2010 - In Part 1 [0] of this two-part article, we introduced various aspects of cloud computing, including the rationale, underlying models, and infrastructures. Before making a decision regarding a multi-tenancy architecture, let's make it more clear what this is all about: Established in 2009, CloudTweaks.com is recognized as one of the leading authorities in cloud computing information. From a functional perspective, data-center server organization has often adopted a three-tier architecture (a specific case of an N-tier architecture). Customers may Also, the Service Level Agreement (SLA) of each tenant can differ. 4 days ago - IaaS, PaaS, and SaaS (infrastructure, platform and software as a service) all have their place in enterprises today and are no strangers to utilizing them. Apr 16, 2012 - Cloud-computing works by delivering computing services as a utility over the internet rather than as a product; the two other branches being Infrastructure as a Service (IaaS), in which physical or virtual machines are licensed for running firewalls, storage, networks, etc., and Platform as a Service The SaaS model has become prominent over the past few years leaving the traditional software model competitively at a loss and lacking in many technical respects for two main reasons. May 27, 2014 - In the past 12 months Microsoft has delivered tremendous innovation including: infrastructure as a service, cloud storage, cloud based device management across heterogeneous devices and Big Data solutions. Director of Cloud Solutions at Gigamon, is a cloud computing design veteran specializing in the architecture of global, highly-available fault-tolerant data center infrastructures. In the following sections, we discuss how this design is handled in Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). 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. Jun 8, 2012 - Multi-tenancy is the key common attribute for both public and private clouds and it applies to all three layers of a cloud: IaaS, PaaS and SaaS. Feb 10, 2010 - The Big Picture. 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. IaaS, PaaS, and SaaS (infrastructure, platform and software as a service) all have their place in enterprises today and are no strangers to utilizing them. User experience will be a deciding factor in separating the future winners from the losers.
