What is Cloud Computing?

What is Cloud Computing? The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

The Concept of Cloud Computing started in the 1950’s

Mainframe Computing seen as the Future of Computing Cost efficient use of Expensive Equipment Multiple Users Dumb Terminals Mainframe Computers

Cloud Computing Evolved from Mainframe Computers

1970’s Virtualization Creating something Virtual rather than actual Operating systems simultaneously in an isolated environment

1990’s Virtualized Private Network Connections Telecommunications companies started offering private networks Leads to Current Uses

Pros and Cons of Cloud Computing

Pros of Cloud Computing Allows for more focus on business and less on managing data centers Ability to develop new applications faster. Financially Globally Pros of Cloud Computing

Cons of Cloud Computing Inconsistent Performance Unsecure Beliefs When the Cloud is Usable or Not Cons of Cloud Computing

Characteristics of Cloud Computing

Cloud Computing Characteristics On-Demand Self-Service Broad Network Access Resource Pooling Rapid Elasticity Measured Service 1. 2. Cloud Computing Characteristics 3. 4. 5.

On-Demand Self Service It is there when you need it. Computer resources can be quickly an easily configured by oneself without human interaction with service provider. Provided resources include email, applications, network or server service.

Broad Network Access Tablets Smartphones Laptops Office Computers

Resource Pooling Sharing/Maximizing Resources The Cloud Service Provider manages all of the clouds physical resources. Cloud Computing creates a pool of resources and they are securely allocated between all customers.

Example of Resources Virtual Processor Storage Network Bandwidth Memory Email Service

Rapid Elasticity You are able to get what you need. Cloud is flexible and scalable to suit personal business needs. Resources can be allocated and released to scale according to demand.

Measured Service You get what you pay for. The resources usage can be monitored, controlled, and reported. Allows for accountability for the provider and consumer.

Service Models Software as a service (SaaS) Platform as a service (PaaS) Infrastructure as a service (IaaS)

Service Models Management

Software as a service (SaaS) Web-based, on-demand distribution model Software is hosted and updated at a central site and does not reside on client computers/servers. SaaS applications are hosted and run by service providers, saving the end user the upfront investment in software purchases and the ongoing upkeep and maintenance.

Software as a service (SaaS) Commercial Software Web access to commercial software  Software is managed from a central location  Software delivered in a “one to many” model   Users not required to handle software upgrades and patches  Application Programming Interfaces (APIs) allow for integration between different pieces of software

SaaS Costs SaaS services could be FREE or billed through subscriptions or usage licenses. Businesses use a pay-as-you-go method (typically monthly) for SaaS applications allowing them to save their capital for core business functions. Free when there is opportunity to generate revenue from streams other than the user, such as from advertisement or user list sales

SaaS Benefits Financial Ease of Use SaaS is subscribed to and not purchased.  The end users are offered less costly and more predictable monthly fees, with no large up-front capital expense. Financial SaaS applications can be easily accessed anywhere the Internet is available through a web browser, thus taking advantage of attributes like usability and innovation of the web. Ease of Use

Installation Ease and Low Maintenance SaaS Benefits Server applications are hosted in a highly-available datacenter, minimizing the effects of power outages and Internet outages from incidents that affect local offices. Uptime Installation Ease and Low Maintenance Upgrades and patches to latest versions take little time and reduce resource requirements. Access Anywhere Customers can connect to their applications anywhere with internet connection.

Where SaaS Makes Sense “Vanilla” offerings where the solution is largely undifferentiated. A good example of a vanilla offering would include email where many times competitors use the same software precisely because this fundamental technology is a requirement for doing business, but does not itself confer an competitive advantage Applications where there is significant interplay between the organization and the outside world. For example, email newsletter campaign software  Applications that have a significant need for web or mobile access. An example would be mobile sales management software  Software that is only to be used for a short term need. An example would be collaboration software for a specific project  Software where demand spikes significantly, for example tax or billing software used once a month

Where SaaS May Not be the Best Option Applications where extremely fast processing of real time data is required  Applications where legislation or other regulation does not permit data being hosted externally  Applications where an existing on-premise solution fulfills all of the organization’s needs Where SaaS May Not be the Best Option

SaaS Examples

Platform as a service (PaaS) Definition: provides a platform allowing customers to develop, run and manage Web applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

Pros of PaaS Automatic Updates Decreased Costs Assured Compatibility Teams Can Collaborate From Afar Pros of PaaS

Lock-In Limited Scalability Cons of PaaS

PaaS Examples

Infrastructure as a service (IaaS) Definition: service model that delivers computer infrastructure on an outsourced basis to support enterprise operations.

Pros of IaaS Cuts Costs Scalability Easy Access Pay-as-you-go model of payment Pros of IaaS

Security Vendor Outages Cons of IaaS
