Difference between cloud computing and distributed computing? [closed]

In my mind what defines cloud computing is that the underlying compute resources (storage, processors, RAM, load balancers, etc) of cloud-based services and software are entirely abstracted from the consumer of the software / services. This means that the vendor of cloud based resources is taking responsibility for the performance / reliability / scalability of … Read more

What is the difference between Cloud Computing and Grid Computing? [closed]

Grid computing is where more than one computer coordinates to solve a problem together. Often used for problems involving a lot of number crunching, which can be easily parallelisable. Cloud computing is where an application doesn’t access resources it requires directly, rather it accesses them through something like a service. So instead of talking to … Read more

What is SaaS, PaaS and IaaS? With examples

IaaS, PaaS and SaaS are cloud computing service models. IaaS (Infrastructure as a Service), as the name suggests, provides you the computing infrastructure, physical or (quite often) virtual machines and other resources like virtual-machine disk image library, block and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks etc. Examples: Amazon EC2, Windows … Read more
