Advantages of cloud computing?

1. Cloud computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet 2. You don't need to make large upfront investments with hardware and spend a lot of time managing that hardware. 3. You don't have to guess your capacity needs, because you can scale up or scale down the amount of resources you use in minutes. 4. You can focus on projects that differentiate your business, not the infrastructure that supports it. 5. You can provision the right type and size of computing resources. Access as many resources as you need almost instantly, and only pay for what you use. 6. Easily deploy your application in multiple regions around the world with just a few clicks

Benefits of Elastic Compute Cloud (EC2)

1. Elastic Web Computing - Enables you to increase or decrease capacity within minutes by creating or deleting EC2 server instances. 2. Completely Controlled - You have complete control over your EC2 instances. You have root access to each one and interact with them as if it was your own machine. 3. Flexible Cloud Hosting Services - You can choose between multiple instance types, operating systems, and software packages. Amazon EC2 allows you to select the memory configuration, CPU, instance storage, and boot partition size that are optimal for your choice of operating system and application. 4.
