Cloud Computing: What is it and why use it.
Wikipedia’s definition says that Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet).[...] Cloud computing entrusts remote services with a user’s data, software and computation.
In your day-to-day life, cloud computing takes the shape of Google Docs, online file share services, mobile sync services and email.
Cloud computing comes into focus when you think about what IT always needs: increase capacity and add capabilities without investing in new infrastructure, training new personnel, or licensing new software.
Low computing costs. First main advantage is bringing down computing costs. Most businesses are affected by the costs of high-end hardware for their employees and the more and more resource hungry apps. Using a cloud makes apps accessible to users from a basic terminal.
Storage and sharing. By using cloud storage, you don’t have to store data on your hard drive anymore. You can access it from any location and download it onto any device of your choice, including laptops, tablets or smartphones. Working in cloud also allows you to edit files simultaneously with other users, making it easier to work away from the office. In the past, memory was limited by particular devices. If you ran out of memory, you would need a USB drive or DVD’s to backup your content. Cloud computing provides increased storage, so you won’t have to worry about running out of space on your hard drive.
Centralized. Everything is centralized and fast. You can now use cloud computing to ensure that everyone is on the same page when it comes to computing standards. One implementation of a new application is enough. Also, clouds are easy to manage and bring down the costs of maintaining separate servers. Cloud computing puts everything together in a very organized manner.
Automatic updates. The cloud computing provider is responsible for the updates – you just have to download them. You don’t need to be an expert to update your device, the provider will automatically notify you and provide the instructions, thus saving precious time.
Security in cloud computing has proven better than scattered networks. With the right amount of skill an intruder can access a physical server and damage or steal data. This kind of access is impossible under cloud as security is much tighter.
