The scalability, agility, and continuous delivery offered by microservices architecture make it a popular option for businesses today. Nevertheless, microservices architectures are not invulnerable to disruptions. Various factors, such as network communication, inter-service dependencies, external dependencies, and scalability issues, can contribute to outages.
Prominent companies like Slack, Twitter, Robinhood Trading, Amazon, Microsoft, Google, and others have recently encountered outages resulting in significant downtime expenses. These incidents underscore the wide-ranging causes of outages in microservices architectures, encompassing configuration errors, database issues, infrastructure scaling failures, and code problems.
