Cloud Computing
Cloud Computing is the pay-as-you-go pricing on-demand delivery of IT resources over the internet. So, instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Who is using Cloud Computing?
Every type and size of organizations are using the cloud for data backup, disaster recovery, email, virtual desktops, software development, and testing, big data analytics, and customer-facing web applications.
For example:
- Healthcare companies are using to develop more personalized treatments for patients.
- Financial services companies are using it to power real-time fraud detection and prevention.
- And IT companies are using the cloud to deliver online games to millions of players around the world and managing the apps and websites data so that it can be available to the user in any type of scenario.
Types of cloud computing
- Iaas – Infrastructure As A Service, it provides access to networking features, dedicated hardware, and data storage space. It gives you the highest level of flexibility and management control over resources.
- Paas – Platform As A Service, using this you don’t need to manage the underlying hardware and operating system and you can focus on your application deployment and management.
- SaaS – Software As A Service, it provides you a complete product that is run and managed by the service provider. Using SaaS you don’t have to think about how the service is maintained or how the underlying infrastructure is managed. You only need to think about how you will use that particular software.
Benefits of Cloud computing
- Agility
- Elasticity
