What is AWS Lambda?

AWS Lambda is a serverless computing service that runs the code without any management of servers by the user. AWS Lambda supports different programming languages like Python, Golang, Java, Node.Js, and many more. The AWS Lambda functions execute the code if there is any specific event occurs or any scheduled time or interval is mentioned. For example, let’s say you are running many EC2 instances. Some of the EC2 instances are not used for a very long period. Running the unnecessary EC2 instances will lead to incurring more costs on the AWS account. You can write a simple code in AWS Lambda that will automatically delete those unused EC2 instances after crossing a certain threshold time. Apart from this Lambda function can automatically scale up or scale down on the amount of traffic it receives. In summary, we can say that AWS Lambda simplifies the development of serverless applications and provides a flexible, scalable, and cost-effective platform for running the code without any code management....

What is Terraform?

Terraform is an Infrastructure As Code tool that is used to create and provision infrastructure on different cloud platforms. Terraform uses a declarative configurational language that is Hashicorp Configurational Language (HCL). It supports multiple cloud platforms like AWS, GCP, Azure, and many more cloud platforms. Using Terraform allows organizations to follow multiple cloud strategies to provision infrastructure. In this way, organizations will not be dependent on a single cloud platform to provision their infrastructure. Apart from this, building complex infrastructure on a cloud platform by using only a console is very hard for infrastructure management. If any type of manual error occurs while creating complex infrastructure, it will be very difficult to pinpoint and fix those errors. If the same complex infrastructure is built using Terraform, the occurrence of such manual errors will be eliminated. This increases the reliability of Terraform to provision the infrastructure on any cloud platform. Overall we can say Terraform has become an important tool for organizations to maintain control, reliability, and scalability on the different cloud platforms....
