Isolate represents an isolated instance of the V8 engine. V8 isolates have completely separate states. Objects from one isolate must not be used in other isolates. When V8 is initialized a default isolate is implicitly created and entered. The embedder can create additional isolates and use them in parallel in multiple threads. An isolate can be entered by at most one thread at any given time. The Locker/Unlocker API must be used to synchronize.

函数计算有很多使用场景，今天介绍定时任务调度
例如每周六生成业务报表
事件类别 资源生命周期事件 HTTP请求 消息队列 调度 调度事件 define event rules that self-trigger regularly and configure a target action to do some regular work. So you can define an Amazon Lambda function or AWS Step Functions state machine as scheduled targets. Hence, when this event is triggered at the specified time or interval you defined, your function or state machine is executed. These types of events are called scheduled Amazon CloudWatch Events

IN VPC 更新前VPC
更新后VPC
While Hyperplane still uses a cross account network interface, it provides the following benefits for Lambda within a VPC:
Reduced latency when a function is invoked by using pre-created network interfaces. The network interface is created when the Lambda function is initially created. Network interfaces are shared across functions with the same security group:subnet combination Function scaling is no longer bound to the number of network interfaces While the new changes make it more conducive for developers to connect Lambda functions to VPCs, the basic architecture doesn’t change in terms of your VPC.
