Entity Framework Core (EF Core) is a modern object-relational mapper (ORM) for.NET Core and.NET applications, enabling efficient database interaction while minimizing the need for raw SQL queries. A fundamental aspect of EF Core is defining Entity Framework relationships, ensuring data consistency and referential integrity in relational databases. This guide explores one-to-one, one-to-many, and many-to-many relationships in EF Core, covering their implementation, configuration, and best practices.

OpenTelemetry is an open-source observability framework designed to instrument, generate, collect, and export telemetry data, including traces, metrics, and logs. It is vendor-agnostic, allowing developers to send data to multiple backend services like Last9, Prometheus, Datadog, or Jaeger without vendor lock-in. For Next.js applications, OpenTelemetry is particularly useful due to the framework’s hybrid rendering approach.

When you think about “AI reliability,” what comes to mind? If you’re like most people, you’re probably thinking of generative AI model accuracy, like responses from ChatGPT, Stable Diffusion, and Sora. While this is certainly important, there’s an even more fundamental type of reliability: the reliability of the infrastructure that your AI models and applications are running on. AI infrastructure is complex, distributed, and automated, making it highly susceptible to failure.

Artificial Intelligence (AI) is reshaping industries worldwide, and Sub-Saharan Africa is no exception. Across the region, governments, businesses, and start-ups are recognising the potential of AI to drive economic growth, improve efficiencies, and enhance decision-making. Yet, as AI adoption accelerates, so does the demand for robust digital infrastructure, including high-performance computing, data centres, and connectivity.

This weekend, I binge-watched Netflix’s new series Zero Day, starring Robert De Niro. The series has sparked excitement and curiosity among cybersecurity enthusiasts and political thriller fans alike. As the title suggests, the show revolves around a cyberattack that exploits unknown vulnerabilities—so-called “zero days”—to wreak havoc on critical systems. But what if the organizations targeted in Zero Day had the right cybersecurity strategy in place?

Snowflake is a powerful, cloud-based data platform designed for high-performance analytics. Whether you're running massive analytical queries, managing structured and semi-structured data, or optimizing data pipelines, visibility into your Snowflake instance is essential. Performance bottlenecks, query execution delays, and unexpected cost spikes can quickly become issues without proper monitoring.

Kubernetes has been facilitating container orchestration for around a decade for both stateful and stateless application workloads. With the recent rise of AI and the advent of tools like Kubeflow and Argo Workflows, Kubernetes is also becoming a first-class citizen when it comes to running AI workloads. When you are training a model on K8s, you may be tweaking many parameters and have to test each of them one by one.

Amazon Web Service offers cloud computing to organizations of all sizes. It provides low-cost cloud storage, nearly unlimited compute resources, and secure remote computing services. Still, many users find AWS confusing. Companies often struggle to understand AWS billing. Aligning cloud spend to actual operational activities for cost allocation is next to impossible. AWS also limits the amount of compute resources you can use based on your location.
