Components of Sustainable MIS Infrastructure

1. Grid Computing 2. Cloud Computing 3. Virtualization

High Availability

: Occurs when a system is continuously operational at all times.

Recovery

Ability to get a system up and running in the event of a system crash or failure that includes restoring the information backup. The primary differences b/ the different types of backup and recovery media, such as DVDs, are speed and cost.

System Virtualization

Infrastructure as a Service (IaaS)

Cloud Service Delivery Model Delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model. Customer rents the hardware and provide its own custom apps or programs; saves money by not having to spend a lot of capital purchasing expensive servers. Service is typically paid for on a usage basis. Offers a cost-effective solution for companies that need their computing resources to grow and shrink as business demand changes.

Grid Computing

Collection of computers, often geographically dispersed, that are coordinated to solve a common problem. Breaks down a problem and distributes the pieces to many machines, allowing faster processing than could occur on a single system. Links thousands of individual computers around the world to create a virtual supercomputer that can process intensive tasks. Makes better use of MIS resources, allowing greater scalability b/c systems can easily grow to handle peaks and valleys in demand, become more cost efficient, and solve problems that would be impossible to tackle w/ a single computer. Allows a company to work faster or more efficiently, providing a potential competitive advantage and additional cost savings.

Categories of Virtualization

Storage Virtualization Network Virtualization Server Virtualization System Virtualization

Cloud Computing

Stores, manages, and processes data and applications over the Internet rather than on a PC or server. Multi-tenant environment; a single architecture hosts multiple customers' applications and data. Offers new ways to store, access, process, and analyze information and connect people and resources from anywhere in the world where the Internet is available. To individual users, the cloud appears as their personal application, device, or document. Offers a company higher availability, greater reliability, and improved accessibility -- all w/ affordable high-speed access. For flexibility, scalability, and efficiency, cloud computing is quickly becoming an option for companies of all sizes. Users can access their programs and documents from wherever they are, whenever they need to.

Emergency

Sudden, unexpected event requiring immediate action due to potential threats to health, saferty, the environment, or property.

Platform as a Service (PaaS)

Supports the deployment of entire systems, including hardware, networking, and applications, using a pay-per-use revenue model. Perfect solution for businesses b/c it passes onto the service provider the headache and challenges on buying, managing, and maintaining web development software, allowing the company to focus on its core initiatives. Helps companies minimize operational costs and increase productivity by providing (Increased Security, Access to Info Anywhere + Anytime, Centralized Info Management, Easy collaboration w/ partners + suppliers + customers, and Increased Speed to Market w/ Significantly Less Cost), without up-front investment.

Unavailable

System isn't operating and cannot be used.

Vulnerability

System weakness, such as a stagnant password, that can be exploited by a threat.

Fault Tolerance

The ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over w/ no loss of service. Enable businesses to support continuous business operations if there's a flood or power outage. Expensive form of backup, only used by mission critical applications and operations.

Technology Failure

The ability of a company to operate is impaired b/c of a hardware, software, or data outage. Can destroy large amounts of data.

Scalability

The system can scale up or adapt to the increased demands of growth. Addresses the various forms of growth, such as new customers, new product lines, or new markets. Anticipating expected and unexpected growth is key to building scalable systems that can support that development.

Reliability

The system functions correctly and provides accurate information. Inaccuracy occurs for various reasons, such as incorrect info entry to info corruption during transmissions. Reliable systems ensure that these are kept at a minimum to reduce risk.

Portability

The system is available to operate on different devices or software platforms.

Usability

Disaster Recovery Cost Curve

Usually supports a disaster recovery plan; charts the following 1. The cost to the company of the unavailability of information and tech 2. The cost to the company of recovering from a disaster over time. The best recovery plan in terms of cost and time is where these costs intersect.

Cloud Bursting

When a company uses its own computing infrastructure for normal usage and accesses the cloud when it needs to scale for peak load requirements, ensuring sudden spikes don't cause poor performance or crashes.
