Malaysia's Payment System   Systemically Important Payment System (SIPS) A systemically important payment system or large value payment system (LVPS) typically processes high-value and time-critical payments Real Time Electronics Transfer of Funds and Securities (RENTAS) Imagine a superhighway for money in Malaysia. This highway is called RENTAS , and it's specifically designed for big, urgent money transfers between banks. Think of it like a high-speed rail for funds, ensuring that large payments happen quickly and smoothly. Why is it so important? Keeps the economy moving: Businesses rely on RENTAS to make large payments, like settling big deals or moving money internationally. If RENTAS were to break down, it could cause major disruptions in the economy.

Real-world example: Imagine a large company in Malaysia needs to pay a supplier overse...

DevOps and chaos engineering   Chaos Engineering is like intentionally breaking things to make your systems stronger. The Core Idea: Instead of waiting for unexpected failures to happen in your live systems, you deliberately introduce controlled "chaos" (like simulating server crashes or network outages) to see how your systems react. Learning from Failure: By observing how your systems behave under stress, you can identify weaknesses, improve your response plans, and build more resilient infrastructure. Netflix's "Chaos Monkey": Netflix pioneered this with their "Chaos Monkey" tool, which randomly terminated instances in their production environment to force their engineers to build systems that could withstand such failures. Beyond Simple Failures: Chaos Engineering goes beyond simple server crashes. It involves complex scenarios, like network disruptions, data center outages, and even human intervention tests ("Game Days") to evalu...
