What is the cloud and how does it work?
What is the cloud? The definition for the cloud can seem murky, but essentially, it’s a term used to describe a global network of servers, each with a unique function. The cloud is not a physical entity, but instead is a vast network of remote servers around the globe which are hooked together and meant to operate as a single ecosystem.
What is the history of cloud computing?
A brief history of cloud computing. Cloud computing dates back to the 1950s, and over the years, it has evolved through many phases that were first pioneered by IBM, including grid, utility and on-demand computing.
What is the difference between on-premises and cloud computing?
Compared to traditional on-premises IT, and depending on the cloud services you select, cloud computing helps do the following: Lower IT costs: Cloud lets you offload some or most of the costs and effort of purchasing, installing, configuring, and managing your own on-premises infrastructure.
What is the most popular cloud computing model?
IaaS was the most popular cloud computing model when it emerged in the early 2010s. While it remains the cloud model for many types of workloads, use of SaaS and PaaS is growing at a much faster rate. Learn more about IaaS Serverless computing

What is Cloud Computing? Examples, Types & Benefits - Guru99
What is Cloud Computing? Cloud Computing is defined as storing and accessing of data and computing services over the internet. It doesn’t store any data on your personal computer. It is the on-demand availability of computer services like servers, data storage, networking, databases, etc.
What is Cloud Computing? Definition, Types & Benefits
Renting IT services often makes more business sense than the DIY approach of an on-site data center.Spending time and money on generating revenue is always a better choice than taking on the burden (and expense) of an on-prem server room.. Cloud computing is the go-to technology behind this mindset.
What is Cloud Computing? Pros and Cons of Different Types of Services
Cloud computing is a method for delivering information technology (IT) services in which resources are retrieved from the Internet through web-based tools and applications, as opposed to a direct ...
What is cloud computing?
Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more— hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.
What is the most common cloud service model?
IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service) , and SaaS (Software-as-a-Service) are the three most common models of cloud services, and it’s not uncommon for an organization to use all three. However, there is often confusion among the three and what’s included with each:
What is SaaS software?
SaaS (Software-as-a-Service) SaaS—also known as cloud-based software or cloud applications—is application software that’s hosted in the cloud and that you access and use via a web browser, a dedicated desktop client, or an API that integrates with your desktop or mobile operating system.
How does cloud computing work?
Cloud computing transforms IT infrastructure into a utility: It lets you ‘plug into' infrastructure via the internet, and use computing resources without installing and maintaining them on-premises.
How much will the cloud computing industry make by 2022?
The global market for public cloud computing has grown rapidly over the past few years, and analysts forecast that this trend will continue; industry analyst Gartner predicts that worldwide public cloud revenues will exceed USD 330 billion by the end of 2022 (link resides outside IBM).
Why do companies use private cloud?
Many companies choose private cloud over public cloud because private cloud is an easier way (or the only way) to meet their regulatory compliance requirements. Others choose private cloud because their workloads deal with confidential documents, intellectual property, personally identifiable information (PII), medical records, financial data, or other sensitive data.
Why are enterprises moving to the cloud?
Many enterprises are moving portions of their computing infrastructure to the public cloud because public cloud services are elastic and readily scalable, flexibly adjusting to meet changing workload demands. Others are attracted by the promise of greater efficiency and fewer wasted resources since customers pay only for what they use. Still others seek to reduce spending on hardware and on-premises infrastructures.

Evolution
Benefits
Future
- As the cloud has gained popularity and acceptance in the computing world, more and more businesses are making the switch. In fact, 75 percent of existing non-cloud apps will move to the cloud within the next three years. Cloud computing benefits continuously evolve with the addition of new services, the conducting of uncompromising research and the creation of innovations th…
Risks
- While cloud computing brings great opportunity, it can also introduce challenges for business leaders and IT departments. By far, the most common disadvantages that continue to taint perceptions about cloud computing are security problems and inconsistent performance.
Results
- The good news is that these challenges can be overcome with a cloud architecture built specifically for your workloads and through the efforts of a strong, reliable cloud service provider.
Security
- Your cloud infrastructure is only as secure as you make it. Responsibility for securing the cloud lies not only with security teams, but also with DevOps and operations teams that are charged with ensuring appropriate security controls are used. Businesses are eager to bring more regulated workloads to the cloud, including any application that manages or contains personal i…
Types
- At first glance, the types of cloud computing seem simple: public, private or a hybrid mix of both. In reality, the choices are many. Public cloud can include shared, dedicated and bare metal delivery models. Fully and partially managed clouds are also options. And, in some cases, especially for existing applications where architectures are too com...
Assessment
- Like any other business-critical decision, selecting a cloud service requires due diligence and research beyond published per-unit rates. It requires an in-depth understanding of workload performance characteristics and needs and the ability to match those needs to the actual offerings of multiple cloud vendors.
Cost
- Cloud service providers have no shared standard units for cloud capacity or common pricing structures, nor are there common specifications for the underlying hardware that runs the cloud applications. As a result, an assumption of total workload cost based on a providers basic per unit rate can easily be off by orders of magnitude.
