Elastic Compute Cloud - EC2

Elastic Compute Cloud (EC2) is a core service provided by Amazon Web Services (AWS) that offers scalable computing capacity in the cloud. With EC2, users can create and configure virtual machines (instances) to run various applications, ranging from simple web servers to complex database clusters.

EC2 provides a wide range of instance types with varying CPU, memory, and networking capabilities to suit different workload requirements. These instances can be quickly launched, configured, and scaled, offering the flexibility to increase or decrease resources as needed.

Additionally, EC2 offers features such as security groups for network security, elastic IP addresses for static addressing, load balancers for traffic distribution, and Auto Scaling to automatically adjust the number of instances based on current demand. Overall, EC2 enables businesses to utilize computing resources on-demand in the cloud, facilitating cost optimization and scalability.

 


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.
