Welcome to Shikisoft Blog!

Last month, I passed the AWS Certified AI Practitioner exam as my 6th AWS certification at the time (I also added Cloud Practitioner later.). I have held active AWS Certified Solutions Architect - Professional and AWS Certified DevOps Engineer - Professional certifications since 2018, renewing each twice and passing 6 Pro-level exams. I’ve also held 3 AWS Associate certifications (Solutions Architect, SysOps Administrator, Developer) since 2017.

After each AWS exam, I write a blog post to share my experience. It’s been a tradition and a log of AWS exams over the years. So, here are my experiences with the AWS Certified AI Practitioner exam in 2026.

As a popular object storage service, Amazon S3 allows you to store data in buckets. However, in most cases, some data becomes irrelevant and less frequently accessed over time. If you leave things as they are, the data will continue to take up space, leading to extra storage costs, not to mention performance inefficiencies.

The good news is that Amazon S3 provides various storage classes for different access patterns that align with your storage performance and cost requirements.

Three months ago, on the last day of November last year, I took and passed the famous AWS Certified Solutions Architect – Professional exam for the third time. Due to recent health problems, I couldn’t study as much as I had hoped. Still, I passed with a decent score of 837/1000 and extended it to 2027. I also renewed my first AWS certificate, AWS Certified Solutions Architect – Associate with this exam and guaranteed to be AWS certified for over 10 years.

The exam was different each time I took it. Thus, as of the end of 2024, I want to share my experiences for the third time. I hope it also helps you in your AWS certification journeys.
