Amazon S3 (Amazon Simple Storage Service)

Amazon Simple Storage Service is a service offered by Amazon Web Services that provides object storage through a web service interface.

Amazon S3 uses the same scalable storage infrastructure that Amazon.com uses to run its e-commerce network.

Amazon S3 can store any type of object, which allows uses like storage for Internet applications, backups, disaster recovery, data archives, data lakes for analytics, and hybrid cloud storage.

AWS launched Amazon S3 in the United States on March 14, 2006, then in Europe in November 2007.

The basic storage units of Amazon S3 are objects which are organized into buckets.

Each object is identified by a unique, user-assigned key.

Buckets can be managed using the console provided by Amazon S3, programmatically with the AWS SDK, or the REST application programming interface.

An object in S3 can be between 1 byte and 5TB. If an object is larger than 5TB, it must be divided into chunks prior to uploading.

When uploading, Amazon S3 allows a maximum of 5GB in a single upload operation; hence, objects larger than 5GB must be uploaded via the S3 multipart upload API.

JSON (JavaScript Object Notation)

JSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Official website :- https://json.org/

Object serialization in java

Serialization is the conversion of an object to a series of bytes, so that the object can be easily saved to persistent storage or streamed across a communication link. The byte stream can then be deserialized - converted into a replica of the original object. When you want to serialize an object, that respective class should implement the marker interface serializable. It just informs the compiler that this java class can be serialized. You can tag properties that should not be serialized as transient. You open a stream and write the object into it. Code for serialization of a java class : Data.java package com . codetalk . serialization ; import java.io.Serializable ; public class Data implements Serializable { private static final long serialVersionUID = 1L; private String firstName ; private String lastName ; /** * @return the firstName */ public String getFirstName () { return firstName ; } /** * @param firstNam

Amazon Lambda (AWS Lambda)

AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. It was introduced on November 13, 2014. AWS Lambda was designed for use cases such as image or object uploads to Amazon S3, updates to DynamoDB tables, responding to website clicks, or reacting to sensor readings from an IoT connected device. Unlike Amazon EC2, which is priced by the hour but metered by the second, AWS Lambda is metered by rounding up to the nearest millisecond with no minimum execution time. AWS Lambda can also be used to automatically provision back-end services triggered by custom HTTP requests, and "spin down" such services when not in use, to save resources. Since December 2020 Lambda supports Docker containers through ECR up to 10 GB in size. Official website :- https://aws.amazon.com/lambda
