What is High Availability?
High availability (HA), which is usually expressed as a percentage of uptime over a specific period, is a measure of a system’s resilience and dependability to continue being accessible and operational. Critical systems like e-commerce platforms, banking applications, healthcare systems, and more require high availability because even a brief outage can result in losses of money, harm to one’s reputation, or even put lives in danger.
How Do We Design for High Availability?
High system availability is crucial for companies in a variety of industries in the current digital era, as system outages can cause large losses. High availability is the capacity of a system to continue functioning and being available to users despite errors in software, hardware, or other disruptions. In this article, we will deep dive into the specification and design to achieve high availability.
