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. …
About a week ago, I took and passed my AWS Sysops Administrator Associate exam, which was my second AWS certification, the first being Architect Associate. This a short recap on what I did and how I achieved the certification in hopes of helping people who want to take it themselves in the future.
I took this certification after about 3 weeks of preparation and a few resources here and there. The materials I used are listed below and they helped me out so much in passing the exam:
While exploring my passion and interest for cloud computing, I have tried and learnt AWS, Microsoft Azure and Google Cloud Platform. I started off on AWS and learnt how to use the AWS Management Console and AWS CLI. However, when I went to learn Azure and GCP, I realised a very glaring feature that AWS lacked. Azure and GCP each had their respective Cloud Shells, which were very useful. GCP had a cloud shell since its birth if I am not mistaken. …
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.
An AMI contains one or more EBS snapshots, which is a template for the instance’s root device volume, launch permissions that control which AWS accounts can you the AMI to set up instances, as well as block devices that specify the root device volume to attach to the EC2 once it is…
If you are new to Amazon Web Services, this simple guide will be a great tool to help you learn how to launch EC2 instances into the cloud. EC2 instances are probably one of the most common and most used services in the AWS Cloud. EC2 instances are virtual machines and servers which customers can easily request and provision in the cloud.
There are many OS that can be used, such as Ubuntu, Windows, Linux and more. Instances also come in many types, with differing prices, compute power, RAM, processors and other options in order to best suit your needs.
You can use EC2 instances to host websites, web applications, applications, services and pretty much anything that needs computing power. …
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. …

Not a fan of the AWS Management Console? Maybe it’s too much of a pain to click through the set-up wizard 10 times just to launch 10 EC2 instances. Well, AWS CLI is just the tool for you.
AWS CLI is a tool which allows you to manage and monitor your AWS services from a terminal session in your client. The benefit of AWS CLI is that you can run automation scripts or shells to easily provision resources. AWS CLI also provides direct access to AWS Service APIs and extended functionality for your needs.
AWS CLI is easy to install and configure for use. It helps you save time by allowing you to just open a terminal session and complete tasks like getting the contents of an S3 bucket or create EC2 instances instead of having to log into the AWS Management Console and click through many tabs. AWS CLI also gives you the ability to automate entire processes and deployments through scripts, which make it easy to automate your cloud infrastructure. AWS CLI also provides support for all the AWS services from one simple tool. …
