Cloud Computing ( What is it ?)

Hello Friends, recently I passed my SAA-C02 exam, and this post list all the resources I utilized to pass through the exam. If you are interested in my journey for the exam please check the following post . Resources utilized(in order):  1. Although I bought Udemy courses from Stephane Maarek and Neal Davis, I chose to start with an ~11hr course on youtube from freecodecamp . The best thing about the course was it was a good pace although it took me ~3-4 weeks to complete it fully. I was taking notes for all the important details(but I must admit they were too many) and hands-on practice wherever I can. 2. While I was trying to complete the freecodecamp video during my spare time(generally tea☕time) I started watching youtube videos.      a) AWS networking video  from AWS Training center (must watch)     b) Introduction to AWS services from AWS Training center       c) Import AWS core Services from Be a Better Dev 3.

On 2nd January bought Cloud Practitioner and Associate courses from Udemy( year-end sale, it was cheap 😉) I joined an online program in January with weekends classes( ~ 8hrs), the classes forced me to stay connected, I must admit it was difficult.  Interestingly I didn't start with the U...

This post belongs to my blog  page related to cloud computing. As a cloud computing practitioner and student, I plan to share all the interesting ways in which cloud infrastructure can be configured sometimes saving  $$s and sometimes just appreciating the idea.  There are five different pricing models for EC2 compute On-Demand Savings plan  Reserved Instances Spot Instance and  Dedicate host Spot Instance is an odd one, Spot Instance prices s are set by Amazon EC2 based on the long-term trends in supply and demand. Amazon EC2 reserves the right to terminate the instance if the Spot price increases above your bid price.  Now, this is very annoying, agree that the compute price for a spot instance is 90% lower than an on-demand instance but there is a possibility that nothing gets done. Amazon will not charge if the spot instance is terminated by Amazon EC2 in the first hour however Amazon EC2 will charge for the nearest second in subsequent hours. If ...
