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/

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

Angular (web framework)

 Angular is a TypeScript-based free and open-source web application framework lead by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS. Google designed Angular as a ground-up rewrite of AngularJS. Angular 14 was released on June 02, 2022. Some new features include typed forms, standalone components, and new primitives in the Angular CDK (component dev kit). All the major releases are supported for 18 months.  This consists of 6 months of active support, during which regularly-scheduled updates and patches are released. It is then followed by 12 months of long-term support (LTS), during which only critical fixes and security patches are released. Official website :- https://angular.io/

HTML5

 HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and final major HTML version that is a World Wide Web Consortium (W3C) recommendation. HTML5 was first released in a public-facing form on 22 January 2008,with a major update and "W3C Recommendation" status in October 2014. Its goals were to improve the language with support for the latest multimedia and other new features; to keep the language both easily readable by humans and consistently understood by computers and devices such as web browsers, parsers, etc., HTML5 introduces elements and attributes that reflect typical usage on modern websites. In addition to specifying markup, HTML5 specifies scripting application programming interfaces (APIs) that can be used with JavaScript. HTML5 is designed so that old browsers can safely ignore new HTML5 constructs. Official website :- https://html.spec.whatwg.org/ Video Link :- https://youtu.be/7E7n2T5B9Nw

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 max...

SingleStore : cloud-native database

 SingleStore is a cloud-native database designed for data-intensive applications. A distributed, relational, SQL database management system that features ANSI SQL support, it is known for speed in data ingest, transaction processing, and query processing. SingleStore primarily stores relational data, though it can also store JSON data, graph data, and time series data. For queries, it compiles Structured Query Language into machine code. SingleStore can store data in either row-oriented tables ("rowstores") or column-oriented tables ("columnstores"). The format used is determined by the user when creating the table. Rather than the traditional B-tree index, SingleStore rowstores use skiplists optimized for fast, lock-free processing in memory. Columnstores store data indexed in sorted segments, in order to maximize on-disk compression and achieve fast ordered scans. SingleStore also supports using hash indexes as secondary indexes to speed up certain queries. A Sing...

Amazon DynamoDB : Fully managed proprietary NoSQL database service

 Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key–value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio. Dynamo had a multi-leader design requiring the client to resolve version conflicts and DynamoDB uses synchronous replication across multiple data centers for high durability and availability.  DynamoDB was announced by Amazon CTO Werner Vogels on January 18, 2012, and is presented as an evolution of Amazon SimpleDB. DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. If Auto Scaling is enabled, then the database will scale automatically. To prevent data loss, DynamoDB features a two-tier backup system of replication and long-term storage. Each partition features three nodes, each of which contains a copy of that partition's data. Each node also contains two data structures: a B tree used to locate items,...
