Now Cloud is Everything

When talking about cloud computing, there are three major categories. It's important to understand them because they are used in conversation, documentation, and training. Explore the three categories of cloud computing IaaS versus SaaS versus PaaS Infrastructure as a service (IaaS) Infrastructure as a Service is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, and operating systems). Instead of buying hardware, with IaaS, you rent it. It's an instant computing infrastructure, provisioned and managed over the internet.  Note When using IaaS, ensuring that a service is up and running is a shared responsibility: the cloud provider is responsible for ensuring the cloud infrastructure is functioning correctly; the cloud customer is responsible for ensuring the service they are using is configured correctly, is up to da...

There are three different cloud deployment models. A cloud deployment model defines where your data is stored and how your customers interact with it – how do they get to it, and where do the applications run? It also depends on how much of your own infrastructure you want or need to manage. Explore the three deployment methods of cloud computing Public versus Private versus Hybrid Public cloud This is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date – everything runs on your cloud provider's hardware. In some cases, you can save additional costs by sharing computing resources with other cloud users. Businesses can use multiple public cloud providers of varying scale. Microsoft Azure is an example of a public cloud provider. Advantages High scalability/agility – you don't have to buy a new server in order to scale Pay-as-you-go pricing – you pay only for what you use, no CapEx costs You're n...

Cloud computing isn't an all-or-nothing service approach. Companies can choose to use the cloud to store their data and execute logic as much, or as little, as necessary to fulfill their business requirements. Existing businesses might choose a gradual movement to save money on infrastructure and administration costs (referred to as "lift and shift"), while a new company might start in the cloud. Let's learn some of the top benefits of cloud computing. It's cost-effective Cloud computing provides a  pay-as-you-go  or  consumption-based  pricing model. This consumption-based model brings with it many benefits, including: No upfront infrastructure costs No need to purchase and manage costly infrastructure that you may not use to its fullest The ability to pay for additional resources only when they are needed The ability to stop paying for resources that are no longer needed This also allows for better cost prediction. Prices for individua...

What is cloud computing? 8 minutes Cloud computing is renting resources, like storage space or CPU cycles, on another company's computers. You only pay for what you use. The company providing these services is referred to as a cloud provider. Some example providers are Microsoft, Amazon, and Google. The cloud provider is responsible for the physical hardware required to execute your work, and for keeping it up-to-date. The computing services offered tend to vary by cloud provider. However, typically they include: Compute power  - such as Linux servers or web applications Storage  - such as files and databases Networking  - such as secure connections between the cloud provider and your company Analytics  - such as visualizing telemetry and performance data Cloud computing services The goal of cloud computing is to make running a business easier and more efficient, whether it's a small start-up or a large enterprise. Every business is unique and has ...

The connected electronic information network has become an integral part of our daily lives. All types of organizations, such as medical, financial, and education institutions, use this network to operate effectively. They utilize the network by collecting, processing, storing, and sharing vast amounts of digital information. As more digital information is gathered and shared, the protection of this information is becoming even more vital to our national security and economic stability. Cyber-security is the ongoing effort to protect these networked systems and all of the data from unauthorized use or harm. On a personal level, you need to safeguard your identity, your data, and your computing devices. At the corporate level, it is everyone’s responsibility to protect the organization’s reputation, data, and customers. At the state level, national security, and the safety and well-being of the citizens are at stake. Chapter 1: The Need for Cyber-security This chapter explains w...
