When did AWS began offering IT infrastructure services to businesses as web services—now commonly known as cloud computing ?

2006

What does PaaS stand for ?

Platform as a Service

Define On_premises Deployment Model

The deployment of resources on-premises, using virtualization and resource management tools, is sometimes called the "private cloud." On-premises deployment doesn't provide many of the benefits of cloud computing but is sometimes sought for its ability to provide dedicated resources. In most cases this deployment model is the same as legacy IT infrastructure while using application management and virtualization technologies to try and increase resource utilization.

What is Cloud Computing ?

The on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the Internet with pay-as-you-go pricing.

Define Platform as a Service (PaaS)

removes the need for your organization to manage the underlying infrastructure (usually hardware and operating systems) and allows you to focus on the deployment and management of your applications.

What does Cloud Computing provide ?

simple way to access servers, storage, databases and a broad set of application services over the Internet.

What does IaaS stand for ?

Infrastructure as a Service

What are the different types of Cloud Computing ?

Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (Saas)

What are the 6 advantages of Cloud Computing ?

Benefit from massive economies of scale Stop guessing capacity Increase spend and agility Stop spending money running and maintaining data centers Go global in minutes

What are the 3 Cloud Computing Deployment Models ?

Cloud Hybrid On-Premises

What is Global Infrastructure ?

The AWS Cloud infrastructure is built around AWS Regions and Availability Zones. An AWS Region is a physical location in the world where we have multiple Availability Zones. Availability Zones consist of one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities. These Availability Zones offer you the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.

Define Cloud Deployment Model

application is fully deployed in the cloud and all parts of the application run in the cloud. Applications in the cloud have either been created in the cloud or have been migrated from an existing infrastructure to take advantage of the benefits of cloud computing. Cloud-based applications can be built on low-level infrastructure pieces or can use higher level services that provide abstraction from the management, architecting, and scaling requirements of core infrastructure.

Define Infrastructure as a Service (IaaS)

contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS provides you with the highest level of flexibility and management control over your IT resources

Define Hybrid Deployment Model

is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud. The most common method of hybrid deployment is between the cloud and existing on-premises infrastructure to extend, and grow, an organization's infrastructure into the cloud while connecting cloud resources to the internal system

Define Software as a Service (SaaS)

provides you with a completed product that is run and managed by the service provider. In most cases, people referring to Software as a Service are referring to end-user applications. With a SaaS offering you do not have to think about how the service is maintained or how the underlying infrastructure is managed; you only need to think about how you will use that particular piece of software. A common example of a SaaS application is web-based email which you can use to send and receive email without having to manage feature additions to the email product or maintain the servers and operating systems that the email program is running on.
