WHAT IS CLOUD COMPUTING? PRESENTED BY BRIAN DUKE, RISHI SINGH & JOSE CERVANTES
INTRODUCTION Cloud Computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The cloud is often used as a metaphor for the Internet. Major examples of cloud computing are Google Drive, Apple iCloud
HISTORY The concept of shared computer access started in the 1950s with the mainframe computing. The first milestone in cloud computing history was the arrival of salesforce.com in 1999, which pioneered the concept of providing enterprise application through a simple website. Another big milestone came in 2009, as Web 2.0 hit its stride, and Google and others started to offer browser-based enterprise applications, though services such as Google Apps.
TYPES OF CLOUD Public Cloud- A cloud is called a "public cloud" when the services are rendered over a network that is open for public use. Public cloud services may be free or offered on a pay-per-usage model. Example, Amazon AWS, Microsoft and Google. Private Cloud- Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally
TYPES OF CLOUD CONT. Community Cloud- Community cloud shares infrastructure between several organizations from a specific community with common concerns (security, compliance, etc.), whether managed internally or by a third-party, and either hosted internally or externally. Hybrid Cloud- Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources.
SaaS (Software-as-a-service). Any application hosted on a remote server(Web browser) that can be accessed over the internet is considered a SaaS. Example: Cisco’s WebEx, Netflix, Dropbox IaaS (Infrastructure-as-a-Service)- it provides off-site servers, storage, networking hardware which can be rented and accessed over the internet. Example: Amazon, Microsoft, Red Hat PaaS(Platform-as-a-Service)- it provides services such as developing or deploying application over the internet using visualized servers. Ex Google app engine, Microsoft Azure LAYERS OF CLOUD COMPUTING
Basic Model of Cloud Computing Database Storage Application servers Computer Networks Web-based services How Cloud Computing is used in businesses today Increase cost savings and efficiency Provides storage, organizational structure and backup for data. Can implement new software packages and solutions on the fly Integrates Data/Apps/Services with multiple devices and interfaces CLOUD COMPUTING TODAY
Increases agility and responsiveness to both IT and product/service problems Can be scaled up or down with relative ease to business plan Revisions and new implementation of latest IT Apps and services can be implemented at low cost COST SAVINGS USING CLOUD COMPUTING
Adds high level of storage capacity with minimal IT knowledge Data storage structure and access is refined for multiple users in different locations Data analysis on cloud can provide valuable information vs using third- party sources Backup storage protection is standard in cloud services DATA STORAGE FEATURES
Accessibility for every device connected to the cloud possible in real time Add automation features through third-party IT cloud services Collaborating with multiple parties simultaneous for product/service development in real time CLOUD COMPUTING INTEGRATION WITHIN BUSINESS
CLOUD COMPUTING AND MANAGEMENT Cloud computing solutions can be adjusted as needed with as much or as little as required for certain projects, reducing cost. Social Media services on the cloud help when recruiting, gathering information on potential customers, and show trends in current marketplace to discuss current and future strategies. Speed of IT solution implementation on the cloud is greatly increased vs traditional IT systems.
EXAMPLES OF CLOUD COMPUTING SOFTWARE AS A SERVICE PLATFORM AS A SERVICE INFRASTRUCTURE AS A SERVICE
SOFTWARE AS A SERVICE (SAAS) A specific application or service offered to a customer via subscription. Examples: Dropbox Quickbooks Many apps on your smartphone or tablet
PLATFORM AS A SERVICE (PAAS) These allow businesses a platform that they can create and disseminate apps and business services that are part of one platform. Examples: Windows Azure Google App Engine
INFRASTRUCTURE AS A SERVICE (IAAS) Here, you can purchase infrastructure (i.e., hardware, servers) from a vendor as well as virtual resources. Examples: IBM Amazon Google Compute Engine
CLOUD COMPUTING FOR SMALL BUSINESS Adobe Forms Central Interactive forms with business intelligence capability; allows businesses to analyze data from submitted forms. Docusign Allows you to digitally sign important documents Office 365
CLOUD COMPUTING WE PROBABLY ALL USE Google Drive Apple iCloud Amazon Cloud Drive Netflix Etc., etc. Cloud computing laptops? Laptops with just enough hard drive space to run a browser, and everything else is done online (Samsung Chromebook)
POTENTIAL DOWNSIDES OF CLOUD COMPUTING Security, stability, and ownership Security Since these services are offered online and usually stored by a third party, these accounts can be hacked and data can be stolen or lost Stability If the third party site running your online service goes down and you rely on it heavily, you are in a heap of trouble. (Intuit example from 2010: site went down for two days and people could not access Quicken, QuickBooks, or TurboTax during that time. Bad for customers and bad for Intuit)
POTENTIAL DOWNSIDES OF CLOUD COMPUTING, CONTINUED Ownership, privacy Intellectual property issues If you hand over certain information to a third party, who owns the data? When officers or regulators want the information, do they need your consent to search the information online? Emerging and evolving privacy issues Problem for certain industries, like attorneys and companies who handle a lot of proprietary information, CPA’s, etc.
