cloud computing by Mind Map: cloud computing

1. dangers

1.1. Security is largely immature

1.2. Much of the technoligy is propietary, and thus can cause lock-in

1.3. Your dependent on the cloud computing provider for your IT resources

1.4. Using the Internet can cause network latency with some cloud applications

1.5. Sometimes cloud providers are more expensive than on-premise systems

1.6. Not in control of costs

1.7. Integration between on-premise and cloud-based systems can be problematic

1.8. Compliance issues could raise the risks of using cloud computing

1.9. Data privacy issues could arise

1.10. M&A activity around cloud providers, could mean constantly adjusting and readjusting your cloud computing solutions

2. reasons

2.1. Scale up IT capacity on-demand

2.2. Align us of IT resources directly with cost

2.3. Provide more IT agility to adapt to new business opportunities.

2.4. Mix and match the right solutions for the business without having to purchase hardware and software.

2.5. Place business volatility into a single domain...the cloud.

2.6. Reduce operational costs, while increasing IT effectiveness.

2.7. Manage huge data sets.

2.8. Create customer-facing systems quickly

2.9. Shift capital dollars to other places needed by the business.

2.10. Balance processing between on-premise and cloud systems

5.2. Who?

5.2.1. An IT system administrator who does not build clouds but deploys onto them, probably in addition to traditional managed systems.

5.2.2. A developer who employs dynamic resource allocation in clouds to speed application or solution creation.

5.2.3. A service provider who needs to handle peak load demands.

5.2.4. A “cloud choreographer” who strings together cloud-based services to implement business processes.

5.2.5. A non-technical end user who accesses services through a browser or via applications such as disk backup to remote storage.

5.2.6. A user of a virtualized desktop on a thin or fat client.

6. What?

6.1. Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.
