History of Cloud Computing

Cloud computing allows users to access applications and files from any device with internet access. It stores and maintains data and applications on remote servers that users can access through the internet rather than local hardware. The concept of cloud computing was first suggested in 1961 as computing sold as a utility. Major companies like Amazon, Google, and Microsoft now offer cloud computing services across various models including SaaS, PaaS, IaaS, public, private and hybrid clouds. Cloud computing provides advantages like cost savings, flexibility, mobility and scalability but also poses risks such as downtime, security issues and bandwidth constraints.

Why Cloud Management Makes $ense

RightScale

RightScale User Conference NYC 2011 - Uri Budnik, Director ISV Partner Program - RightScale Cloud is the most nebulous and abused term in information technology today. It describes multiple, disparate service models and has been retroactively applied to countless legacy technologies in attempts to keep them current. In this session, we'll discuss the cloud technology landscape and where RightScale fits in to drive agility, cost, and time savings above cloud infrastructure. RightScale has been investing heavily for the past four years to make cloud infrastructure easy to leverage. This session will clarify elements that are straightforward, what continues to be difficult, and the impact on your schedule and budget.

GeekSpeak: Cloud Computing

Dawn Quinn

Cloud computing refers to storing and accessing data and programs over the Internet instead of a local computer's hard drive. It provides users access to servers, storage, databases, networking, software, analytics and more through services delivered over the Internet. There are three types of cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Cloud computing provides benefits to businesses such as lower costs, increased productivity, more storage capacity, less downtime and decreased overhead. However, concerns regarding reliability, security, effects on jobs, and lack of regulations remain issues.

Cloud Computing

ibnashad

Cloud computing is internet-based computing where shared resources, software, and information are provided on demand to computers and devices. There are different types of cloud deployment models including public clouds, available to anyone, private clouds set up within organizations, and hybrid clouds that combine internal and external clouds. The main cloud service models are Infrastructure as a Service (IaaS) which provides virtualized computing resources, Platform as a Service (PaaS) which provides development tools, and Software as a Service (SaaS) where software is accessed via the internet. While cloud computing offers potential benefits, security risks and challenges must be addressed.
