With over 200 fully featured services available in Amazon Web Services (AWS), it can be a daunting task if you want to know about every service. Each AWS Service has its own Overview Page, Use Case, Documentation, FAQs, and Pricing pages, which can also contain detailed explanations of how each service works, coupled with its interdependencies with other services. This can lead to your learning focus being derailed into multiple technological areas that you may not have been initially aiming for. This series is an attempt to cut down on that complication. You will find Service Summary Cards (SSC) describing all the W questions (What, Why, When, Where, Who, How, How much?) organized based on services covered in an AWS Certification Exam. These cards are designed to provide the key information and can be useful to anyone who wants to learn about different AWS services, including someone who is not preparing for a certification exam.
