Beginner's Guide to Amazon S3: Scalable Cloud Storage for Student Projects

·2 views

Amazon S3 (Simple Storage Service) is an AWS object storage solution that lets applications store and retrieve files such as images, videos, PDFs, and datasets without relying on physical servers. Data is organized into buckets containing objects, each identified by a unique key, making file management straightforward for developers. S3 was designed to overcome traditional storage limitations like hardware failures, capacity constraints, and high maintenance costs by offering durable, redundant cloud infrastructure. The service automatically scales to accommodate growing storage needs, from megabytes to hundreds of gigabytes, with no manual hardware upgrades required. It also offers multiple storage classes—ranging from S3 Standard to Glacier Deep Archive—allowing developers to balance cost against how frequently data needs to be accessed.

Amazon Athena Lets Users Query S3 Data with SQL, No Servers Required

Amazon Athena is a serverless interactive query service from AWS that enables users to analyze data stored in Amazon S3 using standard SQL, without setting up or managing any infrastructure. Users simply upload their dataset to an S3 bucket, define the data schema in Athena, and run SQL queries that are processed in parallel across the cloud. The service supports multiple file formats including CSV, JSON, ORC, Avro, and Apache Parquet, making it flexible for various data types. Athena is particularly suited for ad-hoc analysis, log exploration, and querying data lakes, eliminating the need for dedicated servers or database clusters. Its serverless model and familiar SQL interface make it accessible for students and small teams who need scalable analytics without complex infrastructure overhead.

Mahidol University Releases Free Thai Speech-to-Text Models for Commercial Use

Researchers from the Biomedical and Data Lab at Mahidol University have released Thonburian Whisper, a suite of Thai-language automatic speech recognition models fine-tuned from OpenAI's Whisper. The models are available in multiple sizes, ranging from small variants that run on standard hardware to a large-v3 version requiring a GPU, achieving Word Error Rates of 6.59 and 7.42 respectively on the Common Voice Thai test set. All models are licensed under Apache 2.0, making them freely usable for commercial applications without requiring additional permission. Distilled versions offering faster inference are also available for developers prioritising speed over maximum accuracy. The project was originally published in 2022 and the models are hosted publicly on Hugging Face.

Dual-Orchestration Pattern Proposed to Separate Machine and Human Workflows in Banking

A technical paper published on DEV Community proposes a dual-orchestration architecture for modern core banking platforms facing conflicting execution demands. The approach, called the Xenon Architecture Standards, pairs Temporal for automated, low-latency distributed transaction workflows with Flowable for multi-week human approval and review processes. The design is mapped to Banking Industry Architecture Network (BIAN) service domains, assigning orchestration responsibility based on state duration, throughput, and human involvement. The paper argues that using a single orchestration engine for both profiles causes problems such as database bloat, thread starvation, and compromised audit compliance. Code examples illustrate how Temporal handles compensating transaction Sagas, including fund reservation, sanctions screening, and account crediting.

AWS CodeDeploy Automates App Deployments Across EC2, Lambda, and ECS

AWS CodeDeploy is a fully managed deployment service from Amazon Web Services that automates the transfer of application code, scripts, and configuration files to various computing environments. It supports Amazon EC2 servers, AWS Lambda functions, and Amazon ECS containers, retrieving application revisions from sources like Amazon S3 and GitHub. The service eliminates manual deployment steps by using a configuration file called appspec.yml to define lifecycle hooks that guide each deployment consistently. CodeDeploy offers both in-place and blue/green deployment strategies, giving developers flexibility to balance speed against risk. It also integrates with CloudWatch to monitor deployment health and can automatically roll back to a previous stable version if a failure is detected.
