Cloud Computing with AWS

Cloud Computing on AWS is designed to help you learn the absolute basic concepts that you must understand to work with any cloud platform (and not just AWS). This course covers Compute, Storage, Network, Identity & Access Management and Cloud Organization. The course uses AWS, the most popular cloud platform in use today, to explain how to practically implement these concepts.

Can somebody tell me What are the cons of cloud computing?


What is virtualization in cloud computing?

How cloud computing works?

What are the security risks of cloud computing?

What is SAAS in cloud computing?

Just as everything in the world, along with pros come a certain number of cons as well. In cloud computing there is Network Connection Dependency, and there are limited features as well. There is a chance of loss of control. There is a higher chance of certain technical issues. Downtime can be considered as one of the biggest disadvantages of cloud computing, low internet connectivity, and power outages are the biggest cause for this.

Cloud works with the help of internet service connection. It enables users to download data and access this data on any device such as a laptop, tablet or a smartphone. Cloud allows users to edit documents simultaneously, thus making it easy for employees to work together. In cloud computing, there are usually two main parts- the front-end and the back-end. These are connected to each other via an internet connection. The front-end refers to the computer side or the client. And the back-end is the cloud section.

SaaS or Software as a Service is a way to deliver applications over the internet as a service. It runs on a SaaS provider and can go by the name of web-based software, on-demand software or hosted software. A few examples of SaaS in cloud computing are Google Apps, Salesforce, DropBox, Mailchimp, ZenDesk, Slack. These platforms allow data to be accessed from any device with an internet connection. It is a method of software delivery where the host maintains the server and database that makes up an application.

Virtualization in cloud computing is the creation of a virtual version of something. This can be a server, a desktop, a storage device, an operating system or network resources too. Virtualization is a technique that allows us to share a single physical instance of an application among multiple customers. This can be done by assigning a logical name to a physical storage, and pointing to that physical resource when demanded.

Cyber Crime has increased significantly over the past few years. With an increase in the amount of crucial data available online, the risk of this data being stolen or used for wrong purposes is also increasing. The main security risks involved in clod computing would be compliance violations, identity theft, malware infections or data breaches. Another threat to security is loss of customer trust due to breach of his/her personal details and potential revenue loss.

AWS (Amazon Web Services) may be a comprehensive, evolving cloud computing platform provided by Amazon that has a mix of infrastructure as a service (IaaS), platform as a service (PaaS) and packaged software as a service (SaaS) offerings. AWS services offers a corporation tools like compute power, database storage and content delivery services.
