Bay Ridge Security Consulting (BRSC) Cloud Computing

What is Cloud Computing  Provides everything: computing power, computing infrastructure, applications, business processes, personal collaboration, as a service to a user wherever and whenever they may need  Definition from National Institute of Standards and Technology (NIST) Model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort of service provider interaction  Pay-per-use computing model in which customers pay only for computing resources they need

What is Cloud Computing Cont.  Potentially growing to a revolutionary concept that could dramatically impact all areas of the IT world Network design Applications Procedures Personnel May even come down to distinguishing computing as “pre-cloud” and “post-cloud” Could be defined as set of hardware, networks, storage, services, and interfaces combined to deliver aspects of computing as a service.

How Cloud Computing can be Used  Stores data, applications, software, and services on group of computers that act as equipment to deliver software and data to end user.  Allows businesses or users to remotely manage, store, customize software or services from any device with Internet access  Businesses can meet with clients from all over the world in real time video  Employees can work from home with access to all business related software, documents, information

Characteristics of Cloud Computing  On-demand self-service  Users can automatically increase or decrease their resources with out having any human interaction from a service provider  Universal client support  Any network device such as desktop, laptop, smartphone, or tablet can access the cloud for resources  Invisible resources pooling  Resources pooled together to serve multiple, simultaneous consumers dynamically assigned or reassigned according to their needs. Customers have no control/knowledge or physical location of resources.

Characteristics of Cloud Computing cont.  Immediate elasticity  Computing resources can be increased or decreased quickly to meet demands  Metered services  Fees based on the computing resources used by consumer  Storage  Less expensive  Off-site location  Increase office space and hard drive space

Cloud Computing Service Models  Cloud Software as a Service (SaaS)  The cloud computing vendor provides access to the vendor’s software application running on a cloud infrastructure  Application software belongs to vendor providing the cloud service  Cloud Platform as a Service (PaaS)  Consumer can install and run their own specialized applications on the cloud computing network  Customer controls deployment of applications, but do not manage/configure any underlying cloud infrastructure (network, servers, operating systems, storage)

Cloud Computing Service Models cont.  Cloud Infrastructure as a Service (IaaS)  Cloud computing vendor lets the customer deploy and run the customer’s own software including operating systems and application  Customer has the highest level of control  Customer has some control over operating system, storage, and installed applications, but can not manage or control underlying cloud infrastructure

Importance of Cloud Computing  Helps in business applications and functionality and usages of computer software  Services, applications, data, and other resources available from any device with Internet access. (easy access from anywhere at any time)  Helps financially  Don’t have to buy cable services with monthly fee  Less equipment need to purchase  Better tracking of activities  Stop technological disasters  Data loss  Virus  System crashes

Importance of Cloud Computing cont.  Easy to share huge amounts of data, software, applications between business offices  Easy access to office data, information to those traveling  Services not interrupted  Saves time  Faster and quicker to solutions helps reduce business risks  Still evolving and will only enhance opportunities for the business.
