One of the main design decisions when designing a solution in AWS is to expect services to fail and implement mechanism to recover and if you need HA, then implement redundancy. Don't assume all the services to be reliable (Unless otherwise stated that they implement redundancy internally). Most of these problems are solved if you are using managed services such as Lambda, API Gateway, S3, Dynamodb & etc but if you are using services like EC2, then you have to design for HA, for example for EC2 using auto scaling and load balancing.
There is everything perfect in the Elastic World besides reliability. Obviously, the reliability and quality of service is dependent on the service provider and if the service provider is down you don't have anything to fallback on. I am a big proponent of AWS, but with the last two outages, I am now designing fallback on local data center servers in case of outages.

在 AWS 中设计解决方案时的主要设计决策之一是预期服务会失败并实施恢复机制，如果需要 HA，则实施冗余。 不要假设所有服务都是可靠的（除非另有说明它们在内部实现了冗余）。 如果您使用 Lambda、API Gateway、S3、Dynamodb 等托管服务，大多数问题都可以解决。 等等，但如果您使用像 EC2 这样的服务，那么您必须针对 HA 进行设计，例如使用自动扩展和负载平衡的 EC2。

除了可靠性之外，弹性世界里一切都是完美的。 显然，服务的可靠性和质量取决于服务提供商，如果服务提供商出现故障，您就没有任何可以依靠的了。 我是 AWS 的大力支持者，但由于最近两次中断，我现在正在设计本地数据中心服务器的后备方案，以防出现中断。
