Cloud computing refers to manipulating, configuring and accessing the applications online. It offers online data storage, infrastructure and applications.

Two advantages of Cloud Computing are as follows-

1. Cost Savings — Cloud Computing is based on pay-per-use model which helps businesses and consumers to significantly reduce their IT expenses. It also provides access to numerous storage facilities and applications which in turn saves the consumer from spending a lot of money on the server setup and installation cost.
2. Reliability — Cloud Computing is much more reliable when it comes to data management, backup and recovery from failures. It provides redundant IT resources, automatic data backup as well as quick fail over mechanism.

1. Picasa is a free program from Google that is used to organize, edit, and share the digital photographs online.
2. Once a user downloads Picasa, it automatically locates photos on the user's PC and moves them to Picasa.
3. It provides 1 GB free online storage space to store photos.
4. It provides a variety of special effects that can be applied to enhance your photos.
5. It lets the user create slideshows, photos collage and videos with the photos.
6. It can easily be synced with any social media account.
7. It also provides online backup for the photos.
8. When a photo is edited, Picasa creates a new version of the photo and the original photo is preserved separately.

The characteristics of Cloud Computing are as follows:

1. On-Demand Self-Service — In Cloud Computing, multiple clients can share the resources and applications at the same time. These Cloud services and resources can be used on-demand and often bought on a subscription basis without human interaction with the service providers.

2. Broad Network Access — The services can be accessed on the Internet anytime and anywhere in the world through multiple devices such as mobile phones, tablets, laptops, etc.

3. Resource Pooling — The resources like virtual server space, network connections, bandwidth etc., are pooled by multiple users, simultaneously from any location, without being interfered by the other users.

4. Rapid Elasticity — This characteristic allows consumers to transparently scale up or scale down the resources according to their computing needs.

5. Measured service — Cloud Computing is based on a pay-for-what-you-use model where resource usage is monitored, measured and reported transparently, based on utilization.
