Introduction to Cloud Computing for Newbies

As a user of cloud computing, you could be accessing your computer services right here....

Cloud computing is a general term for computing services delivered over the Internet, as opposed to computing services hosted inside your own network; on your own premises.

These computing services can be as simple as Internet based email or as complex as a Customer Relationship Management (CRM) application.

Cloud computing offers cost savings, because users don't have to invest capital budget to purchase hardware and software, nor expend the operating costs of electric power, space and cooling for the hardware and employee costs of maintaining the hardware and software.

The major differences between cloud based computing services and in-house or on-premise computing services are that cloud computing is:

  1. On-demand  "use it only when you need it";
  2. Elastic  "you can have as little or as much as you need".
  3. Shared "your computing services are shared with other users".

The end-user often only needs a computer and a browser/thin client or mobile device and browser/mobile application to access a cloud-based application.

There are three different types of clouds:

  1. Public - open to anyone to use
  2. Private - hosted by a an organization for the exclusive use of by its employees, members or partners
  3. Hybrid - a cloud that is part public, part private.

The above types of clouds, can be offered as:

  1. Infrastructure-as-a-Service (IaaS) or
  2. Platform-as-a-Service (PaaS) or
  3. Software-as-a-Service (SaaS).
NIST provides a nice graphical overview of the the types of cloud offerings:

The following series of blog posts will dive into each category in depth as well as discuss security and privacy concerns. In addition, hands-on tutorials on how to build a private cloud will be provided.

IoT & Smart Cities Stories
Recently, REAN Cloud built a digital concierge for a North Carolina hospital that had observed that most patient call button questions were repetitive. In addition, the paper-based process used to measure patient health metrics was laborious, not in real-time and sometimes error-prone. In their session at 21st Cloud Expo, Sean Finnerty, Executive Director, Practice Lead, Health Care & Life Science at REAN Cloud, and Dr. S.P.T. Krishnan, Principal Architect at REAN Cloud, discussed how they built...
When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...

Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
