1. What is CloudFormation? AWS CloudFormation is a service that helps you model and setup Amazon Web Services resources. When building a system on AWS with EC2, RDS, etc., you will need to do some infrastructure environment building work, such as setting up IAM and VPC. CloudFormation is a service that allows you to create templates for such pre-implemented infrastructure environments and applications. Normally, when building an infrastructure, you would choose “t3.
What is CloudFront? CloudFront is a content delivery network service from AWS that delivers videos and applications to users securely and quickly. It delivers videos and applications to users securely and at high speed. cloudFront, in short, is a service that reduces the waiting time for content to start when a user is viewing it. Advantages and disadvantages of CloudFront CloudFront is directly connected to AWS Shield for mitigating DDoS attacks, Amazon S3 for content storage, ELB and EC2.
What is EC2? EC2 is a virtual server construction service provided by AWS. EC2 is the most basic and important service among the various services provided by AWS, and it is the only one that allows you to build a server. Without EC2, you can’t create a box, so you can’t create a general server environment. Without EC2, you can’t create a box, so you can’t create a general server
1. What is AWS IoT? In today’s world, all things are connected to the Internet. All kinds of products, from cars to factories to home appliances, can be connected to the Internet, and information on these products is collected and used to develop new products. This IoT trend will continue to grow in the future. However, the reason why IoT services have not appeared on the market in spite of the high demand is because it is not easy to connect devices to infrastructure (DB, etc.
1. What is Lambda? Lambda is a serverless computing service from AWS. The term “serverless” has been heard a lot lately.

However, engineers who are not familiar with machine learning (even infrastructure engineers) may not even know how to build an environment. AWS’s SageMaker is a service that allows data scientists and developers to easily build machine learning models when they want to build a machine learning environment.
1. What is SQS? SQS is a message queuing service of AWS. You may not be familiar with the term “message queuing”. It’s not a keyword that comes up very often in the field of system development, so many people may not be familiar with it.
