Past, Present and Future: Cloud Computing in Three Minutes Perhaps the most interesting thing about the cloud is just how fluffy it really is. Recent news indicates that it has finally gone mainsteam. Yet at the same time, most people are still not quite clear on what the cloud really is. To get a better understanding, here’s a three-minute summary of where the clouds came from and where they are heading. Looking at the roots of the cloud computing movement, it all really started in the late ‘90s when companies with a Software-as-a-Service (SaaS) business model started surfacing. Perhaps the most well known pioneer is Salesforce.com,

The Great Debate: Is The Cloud Ready for Mission Critical Applications? We all know cloud is the future of IT, but there are still a few unanswered questions. For instance, with all the high-profile cloud outages, is the cloud really ready for mission critical applications? This common question arises because inevitably, we wonder if the cloud is more or less reliable and secure than our own data centers. In a recent survey from North Bridge Venture Partners on cloud computing trends, 50 percent of respondents said they were confident cloud solutions were viable for mission critical business applications. Only three percent
Cloud Computing And Organizational Inertia Having spent this last week at the Cloud Connect event in Silicon Valley, I have had a number of interesting discussions with people involved with various aspects of cloud computing. While industry analysts such as Gartner and IDC are projecting that 80% of all servers running on native hardware are expected to be virtualized by 2020, many service provider and media representatives I’ve spoken with continue to be a little skeptical as far as these projections are concerned. From a technical standpoint, the development effort by industry bellwethers like Cisco, IBM and HP has significantly accelerated the technological development in
PaaS and IaaS: Rising Champions of Cloud Computing In the cloud conversation, Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) appear much less than the famed Software as a Service (SaaS). This is not surprising when you consider that a world already populated with built platforms and infrastructure has but to operate on them. However, offering Platforms and Infrastructure through the cloud has been a boon to the software development field, especially with the recently growing push toward increased collaboration between developers and admins, commonly referred to as Development Operations (DevOps). Distinctions and Utilization Though somewhat easy
Multi–tenancy in the cloud: Understanding its benefits Multi–tenancy refers to a principle in software architecture where a single instance of a software application serves multiple customers, also known as tenants and is regarded as one of the essential attributes of Cloud Computing. 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. Customers may have the ability to configure some parts of the application, such as the color of the user interface or business rules, but they can’t customize the application’s code. This means
