Cloud Computing is how most start-ups and many larger businesses run their IT systems today. New projects are often deployed on the cloud rather than into legacy data centres. During this session, Jimmy Morgan (Senior Cloud Architect) and Kin Li (Senior Technical Account Manager) from Amazon Web Services (AWS) introduced to students the core concepts of Cloud Computing, and an overview of AWS.
Kin introduced the basics of cloud and what it is used for – “Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centres 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).”
Jimmy demonstrated the 3 demos shown during the presentation
They talked about many different services provided by AWS which includes running virtual machines, servers and storing data on the cloud.
Talked about a time when a company spent $500,000 on equipment and took 1 month to complete a task. If they used AWS cloud services it would cost dramatically less and only take a week.
The idea of “pets vs cattle” being the same as having your own physical server vs using the cloud. If something went wrong with your pet, you would have to spend money and time fixing the problem. Cattle are seen as more easily replaceable, and you’d more likely replace the herd than focus on fixing each cow’s problem. This is comparable to shutting down the cloud and starting a new one!
