CLOUD COMPUTING - ANU REDDY CHADA

Cloud computing

DEFINITION:

Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal man

                        

EXAMPLES OF CLOUD BASED EXTENSION APPROCHES:

(1)  DIGITAL GREEN -   it is an organization that works to increase agricultural productivity by training small and marginal farmers via short instructional videos.

(2)  ESOKO -   here smallholder farmers can sign up to esoko to receive a package of weekly advisory services through news ,voice messages etc. .

(3)  FRONT LINE SMS -   it has a mission that the empowerment of people to use their own ingenuity to craft solutions using mobile technology.

(4)  LIFE LINES INDIA – it brings agro advisory right to the field of a farmer.

(5)  M KISAN – it uses mobile technologies to strengthen farmer- extension expert linkages in India. it uses additional information provided by digital green.

Advantages of Cloud Computing

(1) Cost Savings -Perhaps, the most significant cloud computing benefit is in terms of IT cost savings. in fact, cloud services are extremely affordable for smaller businesses.

(2)Reliability-With a managed service platform, cloud computing is much more reliable and consistent than in-house IT infrastructure.

(3)Manageability -Cloud computing provides enhanced and simplified IT management and maintenance capabilities through central administration of resources, vendor managed infrastructure and SLA backed agreements.

(4)Strategic Edge -Ever-increasing computing resources give you a competitive edge over competitors, as the time you require for IT procurement is virtually nil.

Disadvantages of Cloud Computing

(1)Downtime -As cloud service providers take care of a number of clients each day, they can become overwhelmed and may even come up against technical outages.

(2)Security -Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks.

(3)Vendor Lock-In -Although cloud service providers promise that the cloud will be flexible to use and integrate, switching cloud services is something that hasn’t yet completely evolved. Organizations may find it difficult to migrate their services from one vendor to another

(4)Limited Control -Since the cloud infrastructure is entirely owned, managed and monitored by the service provider, it transfers minimal control over to the customer.
