2023-04-05T07:09:33+00:00

My team and I took the recently released AWS Certified Solutions Architect - Associate SAA-C03 exam version recently. The SAA-C03 test replaced the old SAA-C02 exam version last August.

Building Dynamic Start and Stop Scheduler Functions for Non-Distributed Applications Under Auto-Scaling Group

2023-05-26T04:50:32+00:00

In AWS, it’s of utmost importance to consider the cost in every aspect. In fact, cost optimization is one of the 6 pillars of a well-architected framework, therefore, it must be included in every step in building solutions in AWS.
