Utility computing:
Utility computing is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific rather than a flat rate.
It is the process of providing computing services through service through an on-demand. Pay-per-use billing method.
Utility computing is a computing business model in which the provider owns, operates and manages the computing infrastructure and resources, and the subscriber accesses it as and when required.
Sun was the first to offer utility computing and Hewlett Packard followed a year later.
Obstacles and opportunities for growth of cloud computing.
Sr No. | Obstacle | Opportunity |
---|---|---|
1. | Availability of service | Use multiple cloud providers. Use elasticity to prevent distributed denial of service attacks. |
2. | Data lock-in | Standardize APIs, use compatible software to enable surge computing |
3. | Data confidentiality and auditability | Deploy encryption, VLANs, Firewalls, geographical data storage |
4. | Performance unpredictability | Improved VM support, flash memory |
5. | Scalable storage | Invent a scalable store |
6. | Bugs in large | Invent a debugger the relies on distributed VM's |
7. | Software licensing | Pay-for-use licenses. Bulk-use scales |
8. | Reputation | Offer reputation - guarding services like those for email |
