Chapter 7. Understanding Linux High Availability

High Availability (HA) is not just an industry term. The fact that something needs to be available usually also means that it is super important, and that the service must be available to clients, no matter the cost.

High Availability is important in the PostgreSQL world. A database is the central component of most setups, and therefore, availability of the service is the key.

In this chapter, the following topics will be covered:

Understanding the purpose of High Availability
Measuring availability
Linux-HA (Heartbeat), STONITH, and Pacemaker
Terminology and concepts
PostgreSQL and High Availability

Modern Computer Vision with PyTorch

Modern Computer Vision with PyTorch

This book provides a hands-on approach to solving over 30 prominent real-world computer vision problems using PyTorch 2.x on actual datasets. Here you'll learn to build a neural network from scratch and optimize hyperparameters, perform image classification, multi-object detection, segmentation, and more. You'll also explore facial expression manipulation and combining CV with NLP and RL techniques, build generative AI applications, and take your model to production on AWS. By the end of this book, you'll master modern NN architectures and confidently solve real-world CV problems.
