Self-managed multi-tenant vector search with Amazon Aurora PostgreSQL

Organizations are using generative AI and machine learning tools to extract value from unstructured data, employing specialized machine learning models to convert data into vectors for efficient searching and retrieval. Amazon Aurora PostgreSQL-Compatible Edition, with the pgvector extension, allows developers to create a vector store for generative AI applications. Multi-tenant architectures in software-as-a-service (SaaS) applications ensure tenant data isolation to maintain security and privacy. In a multi-tenant scenario, home survey requests are processed, and survey reports are stored in Amazon S3. Embedding models convert these documents into vector embeddings, which are stored in a vector store. There are two approaches to building a vector-based application: a self-managed approach, where developers handle data processing and queries, and a fully-managed option using Amazon Bedrock Knowledge Bases. The self-managed approach involves coding to process data, generate vector embeddings, and store them in Aurora. The architecture includes data ingestion via AWS Lambda, embedding conversion, SQL queries for data retrieval, and response enhancement using a large language model (LLM). Key terminologies include vector embeddings, embedding models, chunking, pgvector, HNSW index, and IVFFlat index. The process of creating a vector store involves configuring the Aurora PostgreSQL database, enabling the pgvector extension, and establishing a schema for the vector store. The vector table includes fields for UUID, vector embeddings, text chunks, metadata, and tenant identification. Data ingestion requires coding to convert data into embeddings and insert them into the database. Retrieval of vector data is crucial for enhancing prompts sent to LLMs, with various distance functions supported for identifying similar vectors. Multi-tenancy is enforced using row-level security in PostgreSQL, ensuring tenant data isolation. The process includes updating query functions to support tenant isolation and setting the current tenant ID for queries.

“If we can do it… This will be something groundbreaking”: PUBG creator Brendan Greene is five years into making a 10,000km “realistic Minecraft” – but there’s still a decade to go

Brendan Greene, known for creating PUBG, is working on a new project called Prologue, which tests innovative terrain generation technology for his larger vision, Project Artemis. Prologue aims to refine machine learning algorithms that can produce over 4 billion unique map configurations. Greene acknowledges past leadership challenges but credits CTO Laurent Gorga for fostering a collaborative development approach. He estimates that achieving Project Artemis could take up to a decade and emphasizes the importance of Prologue's commercial success for securing resources. Greene envisions Project Artemis as a vast, player-driven universe, inspired by games like Minecraft and No Man's Sky, with a world measuring 10,000 square kilometers. He aims to create an environment where players can craft diverse experiences and distances himself from commercial interpretations of the Metaverse, focusing instead on genuine user-generated experiences.

Microsoft thinks it could stop this dangerous scam forever

Microsoft has launched a new ‘Scareware blocker’ feature for Edge web browsers on Windows PCs, designed to enhance user protection against tech support scams. This machine learning threat detection software identifies signs of scareware in real-time and aims to reduce the prevalence of such scams, which cost victims millions annually according to the FBI. The technology analyzes new websites and uses a SmartScreen feature for global protection, processing information locally without uploading images to the cloud. When a potential threat is detected, Edge exits full-screen mode, stops aggressive audio playback, and alerts the user. Users can report malicious sites or inaccuracies to improve the model. The feature is available to all Edge users upon updating their browser.

Data protection advancements expected to shape 2025 security

Andrew Eva, the Global CIO of Assured Data Protection, predicts that by 2025, there will be a seamless integration of backup systems with ransomware detection, antivirus technologies, and intrusion detection systems. He highlights a collaboration between Rubrik and Google to provide enterprise customers with insights into known exploits for better early detection of malicious codes. Disaster recovery systems will take on a more frontline role in cyber threat management, utilizing machine learning to identify potential viruses. Ransomware is expected to remain the top cyber threat, prompting organizations to prioritize disaster recovery and backup solutions. Concerns about data security in relation to artificial intelligence will lead organizations to seek assurances regarding data protection from managed service providers (MSPs). The criteria for cyber insurance are tightening, making MSPs essential for businesses to meet these requirements. There is also an anticipated surge in demand for Backup-as-a-Service (BaaS), especially in healthcare, driven by resource constraints and a shift towards operational expenditures.
