The Beginning

Last year, I was first introduced to the concept of cloud computing. I was a 1st-year cybersecurity student with a strong interest in cybersecurity and development. However, when I saw an email from my school on training to represent the school in a cloud computing competition, I thought “Why the heck not” and signed up for it even though I hadn’t the faintest idea what cloud computing was like.

I was introduced to an AWS Cloud Architecting course from AWS Academy themselves. It was filled with lecture videos and practical lab sessions that were to be self-studied. …

Amazon Machine Images (AMIs) help speed up the process of setting up EC2 instances by providing a packaged environment containing software configuration and other information required to start an EC2 instance.

Treat AMIs like a template, which contains the operating system, application server and any additional dependencies or application that is a part of it.

When setting up an EC2 instance, you have to choose an AMI. When you launch your first EC2 instance, you will probably use default AWS AMIs or community AMIs, but you can save you own as well.

About a week ago AWS introduced FIFO topics for Amazon SNS. FIFO helps preserve message order and ensures there is no duplicate message delivery to SNS subscribers.

Amazon Simple Notification Service is used as a pub/sub messaging system, where a message is published to a topic and delivered to all subscribers of that topic. SNS allows message delivery to a large number of subscribers, who can each set filter policies to only receive messages relevant to them.

You can use topics to fan-out messages to multiple queues or applications to help decouple microservices and create distributed systems or serverless applications.

With SNS FIFO, message ordering and deduplication can be achieved. …
