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.

Public clouds dominate IT conversations but the next phase of cloud evolutions are "multi" hybrid cloud environments. The winners in the cloud services industry will be those organizations that understand how to leverage these technologies as complete service solutions for specific customer verticals. In turn, both business and IT actors throughout the enterprise will need to increase their engagement with multi-cloud deployments today while planning a technology strategy that will constitute a significant part of their IT budgets in the very near future. As IoT solutions are growing rapidly, as well as security challenges growing exponentially, without a doubt, the cloud world is about to change for the better. Again.
While more companies are now leveraging the cloud to increase their level of data protection and management, there are still many wondering “why?” The answer: the cloud actually brings substantial advancements to the data protection and management table that simply aren’t possible without it. The easiest advantage to envision? Unlimited scalability. If a data protection tool is properly designed, the capacity should automatically expand to meet any customer’s needs. The second advantage: the cloud is the simplest way to centralize the storage of all secondary data sources while also providing unlimited compute that can be used to gain additional insight and business value from that data. Finally, the ability to do automated Disaster Recovery (DR) without maintaining a DR facility is unquestionably a major value of the cloud, and simply isn’t possible otherwise. Join W.

At CloudEXPO Silicon Valley, June 24-26, 2019, Digital Transformation (DX) is a major focus with expanded DevOpsSUMMIT and FinTechEXPO programs within the DXWorldEXPO agenda. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term. A total of 88% of Fortune 500 companies from a generation ago are now out of business. Only 12% still survive. Similar percentages are found throughout enterprises of all sizes.
The platform combines the strengths of Singtel's extensive, intelligent network capabilities with Microsoft's cloud expertise to create a unique solution that sets new standards for IoT applications," said Mr Diomedes Kastanis, Head of IoT at Singtel. "Our solution provides speed, transparency and flexibility, paving the way for a more pervasive use of IoT to accelerate enterprises' digitalisation efforts. AI-powered intelligent connectivity over Microsoft Azure will be the fastest connected path for IoT innovators to scale globally, and the smartest path to cross-device synergy in an instrumented, connected world.
As you know, enterprise IT conversation over the past year have often centered upon the open-source Kubernetes container orchestration system. In fact, Kubernetes has emerged as the key technology -- and even primary platform -- of cloud migrations for a wide variety of organizations. Kubernetes is critical to forward-looking enterprises that continue to push their IT infrastructures toward maximum functionality, scalability, and flexibility. As they do so, IT professionals are also embracing the reality of Serverless architectures, which are critical to developing and operating real-time applications and services. Serverless is particularly important as enterprises of all sizes develop and deploy Internet of Things (IoT) initiatives.
