In this short series, I outline the notes that I took while preparing for the AWS Cloud Practitioner exam.
These are my personal notes that I have made while working through the A Cloud Guru exam practitioner course. They are in no way official notes from AWS.
I would advise you that if you do use my notes to help you revise for this exam, that you use them as a supplement to the most recent information in the White Papers, Exam Guide and go over your knowledge with practice exam papers.
What is Cloud Computing?
The on-demand delivery of compute, databases storage, applications and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing.
6 Advantages of Cloud Computing
- Trade capital expense for variable expense
- Benefit from massive economies of scale
- Stop guessing about capacity
- Increased speed and agility
- Stop spending money running and maintaining data centers
- Go global in minutes
3 Types of Cloud Computing
- Infrastructure As A Service (IAAS) – You manage the server and OS. Data center provider has no access to your server e.g. EC2
- Platform As A Service (PAAS) – Someone else manages the hardware and OSs. You focus on your applications. E.g. LightSail, Elastic Beanstalk
- Software As A Service (SAAS) – All you worry about is the software and how you want to use it E.g. Gmail
3 Types of Cloud Computing Deployments
- Public Cloud – AWS, Azure, GCP
- Hybrid – Mix of public and private
- Private Cloud (On Premise) – You manage it in your datacenter. Openstack or Vmware.
