Simple Storage Service - S3

Simple Storage Service (S3) is a cloud storage service provided by Amazon Web Services (AWS), allowing users to store and access data in the cloud. S3 offers a scalable, secure, and highly available infrastructure for storing objects such as files, images, videos, and backups.It operates on a bucket structure, where buckets are containers for the stored objects. These objects can be managed and retrieved using a RESTful API or various AWS tools and SDKs. S3 also provides features such as versioning, encryption, access control, and a variety of storage options that can scale based on the use case.


Amazon Web Services - AWS

Amazon Web Services (AWS) is a cloud computing platform provided by Amazon.com. It offers a wide range of services including computing power, databases, storage, content delivery, and many other tools that help businesses and developers operate their applications and infrastructure in the cloud.

AWS allows companies to use resources and services on demand rather than owning and maintaining physical hardware and infrastructure. This enables them to operate more scalable, flexible, and cost-effective setups as they only pay for the resources they actually use.

Some of the most well-known AWS services include Elastic Compute Cloud (EC2) for deploying virtual servers, Simple Storage Service (S3) for data storage, and Amazon RDS for managed relational databases. AWS has a vast reach and is utilized by businesses of all sizes for a variety of applications and workloads.

 


AWS Lambda

AWS Lambda is a "serverless" service provided by Amazon Web Services (AWS) that allows developers to execute code without managing or provisioning servers. With Lambda, developers can write functions and upload them to run in the cloud on an as-needed basis without managing infrastructure.

It operates based on "event triggers" that initiate the code, such as uploading a file to an Amazon S3 bucket or receiving a message in an Amazon Simple Queue Service (SQS) queue. Lambda scales automatically to meet the code's demands, and developers only pay for the actual compute power used, as billing is based on the number of function invocations and their duration.

 


Function as a Service - FaaS

Function-as-a-Service (FaaS) is a cloud computing model that allows developers to execute individual functions or code snippets without having to worry about the underlying infrastructure. Essentially, FaaS enables developers to upload and run code in the form of functions without dealing with the deployment, scaling, or management of server infrastructure.

The idea behind FaaS is that developers only need to write and upload the code that fulfills a specific function. The FaaS platform then handles the execution of this code when triggered by events or requests. A typical example of FaaS is using serverless computing in the cloud, where developers deploy functions in the cloud that run only when needed.

Popular FaaS platforms include AWS Lambda by Amazon Web Services, Azure Functions by Microsoft Azure, and Google Cloud Functions by Google. They allow developers to upload and execute code in various programming languages, simplifying application development and scalability without worrying about the underlying infrastructure.

 


Serverless

Serverless refers to a cloud computing approach where developers can build and run applications without having to manage the underlying infrastructure, such as servers or server instances. In the serverless model, the responsibility for provisioning, scaling, and maintaining servers lies with a cloud service provider.

Essentially, serverless doesn’t mean there are no servers; it means developers don't need to concern themselves with managing those servers. The infrastructure is automatically managed and scaled by the provider as needed, allowing developers to focus on writing application code without worrying about the underlying hardware or server configuration.

Serverless applications are often broken down into functions or services known as "Function-as-a-Service" (FaaS). Developers write functions that respond to specific events and are managed and executed by the serverless provider. These functions scale on demand and are billed based on actual usage.

Benefits of serverless include improved scalability, cost savings through usage-based billing, reduced operational complexity, and the ability to focus on developing application logic rather than managing infrastructure. It's commonly used for various types of applications such as web applications, APIs, data processing, and more.
