Clouducation 101: What is the Cloud?

Public Cloud | Private Cloud | Public Cloud

by FortressITX Dir. of Datacenter Operations, Salvatore Poliandro

What is the “Cloud”? What is “Cloud” computing? These are questions I get all the time. For the vast majority of people, the “Cloud” is a lofty term having to do something with computing or, let’s be honest, puffy cumulus wisps of moisture floating around in the sky. The truth is the “Cloud” is a marketing term made up to sell a service (note: the quotation marks around “Cloud” were to delineate that marketing term. From here on out, “Cloud” will be written sans quotation). That service, the Cloud, is computing and storage capacity as a service. In human terms, it is a system of delivering computing and storage needs via three types of computing services: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Although this is true, for most people Cloud can be broken down into two categories, Public or Private.



The Public Cloud is the ability to use services that do not reside on your local computer. Examples are Spotify, Netflix, Dropbox and Gmail. All of those services allow a consumer to access the Cloud by storing their information in a datacenter and streaming that information to their own personal computer. The Public Cloud is called “public” because although it allows individuals to stream movies from Netflix or have an email account via Gmail, data is maintained in a public infrastructure.

Think of this infrastructure as a scalable apartment building. In an apartment building (Public Cloud) there are separate apartments all full of different tenants (multitenancy). Each tenant uses the space allotted to him or her for their own personal use without every encroaching on another tenant’s space. The same concept applies in the Public Cloud however unlike a real apartment building, if you need more storage capacity you pay for more storage capacity. The ability to pay for only what you use and need is called scalability. Within a Public Cloud infrastructure, users pay for what they need and never encroach on another tenant. In the Private Cloud, scalability still applies however the infrastructure is different.

In a Private Cloud, as the name suggests, you are no longer part of a multitenancy infrastructure. Rather you are the only tenant. In terms of scalability, because the infrastructure is different, you now pay for an allotted and determined storage capacity as opposed to paying for how much space you need at that moment. Simply put the benefit of a Private Cloud isn’t in scalability, it’s in security.

Within the Private Cloud because you are alone in your infrastructure, you don’t have to worry about what other tenants are doing that could potentially cause a breakdown in security. Rather your main concern is illegal access into your Cloud from the outside world. A good hosting company will deploy stringent firewalls across a their Private Cloud to make sure nothing illegal takes place.

The other large added benefit of a Private Cloud is VPN. VPN, or Virtual Private Network, allows a company to make a direct connection with their hosting company or between two offices to share vital information, make repairs, fix glitches etc. A VPN is the ultimate in Cloud Computing because it allows for a secure private direct connection to share sensitive data without having to worry about the data being compromised.

In terms of who uses both options, private consumers tend to use the Public Cloud while companies with vital information tend to use the Private Cloud. There is also a combination of both, appropriately titled the Hybrid Cloud.

The Hybrid Cloud is an infrastructure in which a company provides and manages some resources in-house and manages other externally. Whatever these resources are, legacy Nortel phone system, a hosted exchange system, an internal APP development system, is up the company. By using a Hybrid Cloud, companies can take advantage of the scalability features of the Public Cloud while at the same time avoiding opening themselves up to third-party security scares.

Now that you know what the Cloud is and the different types of Cloud infrastructure, the next question we have to answer is, how does the Cloud affect me as a consumer, as someone working for a business (Ex. a mobile app developer) and as a business?

The answer to that question to come in next week’s blog post.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
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 ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
