Join David Linthicum for an in-depth discussion in this video What is cloud computing?, part of Planning a Small Business Cloud Strategy.
- [Instructor] So first let's talk about why we're into cloud computing for small business. We're gonna cover a couple of things, including describe the origins of cloud computing including directions and its current heading. Describe the components of modern cloud computing including private, public, and hybrid cloud. Explain the core business case for cloud computing and how you can determine if cloud computing is right for you, and we're gonna provide a summary of the emerging market and how enterprises are shifting to cloud computing.
So first cloud computing provides you with the ability to leverage remote systems on an on demand basis over the open internet. So in other words, we leverage computer resources as we do websites, we're able to get into a system. Log on, and access resources such as storage, compute, machine learning systems, databases, pretty much anything you can find in a data center. Number two, it provides the ability to pay for only the resources that you use. Cloud computing uses a pay-per-drink kind of approach.
So therefore we get bills in a utility basis. Very much like your power bill or your water bill. You're only gonna pay for the resources that you leverage and the time in which you leverage them. Cloud computing provides elasticity, the ability to scale up to the levels that you need, and then when you're done with the need for those resources to scale back to smaller levels, and therefore pay for only what you leverage and so you're able to basically scale up and scale back. So where did cloud computing come from? Well this is kind of a date line, a timeline of sorts, that really kind of explains where we kinda came from.
So data centers emerged in the 1940s, with limited use of computing and we saw in the 1960s through the 1980s the rise of timesharing where you're finding that they're very much similar patterns to timesharing and cloud computing, and then moving into distributed computing, use of grids and that lead to the rise of the PC. The rise of Client/Server, the rise of the web and now we're going through the rise of the cloud. Which has been going on for about the last 10 years. We're learning how to leverage resources access computing systems such as storage, compute applications over the open internet and therefore sharing those resources.
Therefore becoming much more effective and efficient in how we're leveraging those resources therefore charging less money to those who are leveraging those resources. Therefore it's an important part of small business because ultimately we're looking to run our business as inexpensively as possible and leveraging the resources allow us, to punch above our weight. So characteristics of cloud computing, well it's on-demand self-service. Ubiquitous network access, resource pooling, pay per use.
We also have delivery models such as Software as a Service or SaaS and that means we're able to consume applications over the open internet. Typically through things that resemble websites but they are in essence applications. Salesforce.com is an instance of that. Platform as a Service, or PaaS, the ability to consume developer resources over the open internet such as test, dev, deployment. And then finally Infrastructure as a Service, or IaaS. The ability to consume basically things that we'd find in our data center such as storage, compute, platforms, databases, things like that.
Complete infrastructure which is available on demand. Moving forward we have deployment models, such as private cloud, the ability to in essence own the cloud and therefore nobody else can use it. Public cloud, the ability to leverage a cloud with other folks, other resources, other companies and then hybrid cloud the ability to leverage a paired private and public cloud so you really kind of get the best of both worlds. So what's next? Well we think it's gonna be the establishment of cloud computing as a common practice and technology, and we're seeing that today.
Almost 40% of applications that exist in the Global 2000 Enterprises, and pretty much 80% of applications that exist in small businesses have moved or are moving to cloud. The emergence of new capabilities in the cloud, we're finding that there's more R&D dollars that are being placed in cloud computing than there are with traditional on premises systems. So going forward, our ability to in essence, leverage advanced technology through these cloud based systems are becoming commonplace, and finally the migration of applications to cloud based systems.
The ability to in essence, move our existing workload which may exist on PCs or servers or in a data center to a cloud based technology where we're able to run cheaper, but also more agile and the ability to expand as we need.
