Lambda falls under “Compute” service in AWS (Amazon Web Services). Using Lambda we can code without provisioning or managing servers. Lambda automatically runs our code without requiring us to provision or manage servers. We just need to write the code and upload it to the Lambda Function. Lambda executes the code only when needed. It grows automatically supporting from a few requests to thousands of requests. We are charged for every 100ms our code executes and the number of times it is triggered. We are charged only for the compute time our code consumes and not charged when the code is not being executed.

VPC (Virtual Private Cloud) falls under the service "Network and Content Delivery" in AWS (Amazon Web Services). VPC provides us with a virtual private isolated cloud. In short, we can have a private network that is isolated from all other networks on AWS. We have complete control over all the components that are responsible for building the network. We can have IPs, CIDR (Classless Inter-Domain Routing) blocks of our choice. We can define our own rules in routing tables. We can have a public network, a private network or a private network with access to the Internet. We can have security groups that help restrict the network and access to it. We can have peering between two isolated networks, from site to site VPN. Click here to read the complete version of this article written by me available on howtoforge .

S3 (Simple Storage Service) falls under “Storage” service in AWS (Amazon Web Services). In simple words, S3 is nothing but an object storage where you can store your objects (Files, Videos, Images, Documents, and any-type-of-file).

We can have access to our data whenever and wherever needed having access to the Internet at the lowest possible cost.
