AWS: API, Dynamo and Lambda Review, Research, and Discussion What are serverless functions? is a programmatic function written by a software developer for a single purpose. It's then hosted and maintained on infrastructure by cloud computing companies. These companies take care of code maintenance and execution so that developers can deploy new code faster and easier. If you were to create a system that emulated Lambda functions, how would you do it? Open the Functions page on the Lambda console. Choose Create function. Describe how a CDN works? At its core, a CDN is a network of servers linked together with the goal of delivering content as quickly, cheaply, reliably, and securely as possible. In order to improve speed and connectivity, a CDN will place servers at the exchange points between different networks. These Internet exchange points (IXPs) are the primary locations where different Internet providers connect in order to provide each other access to traffic originating on their different networks. By having a connection to these high speed and highly interconnected locations, a CDN provider is able to reduce costs and transit times in high speed data delivery. Document the following Vocabulary Terms Serverless Functions: is a programmatic function written by a software developer for a single purpose. It's then hosted and maintained on infrastructure by cloud computing companies. These companies take care of code maintenance and execution so that developers can deploy new code faster and easier. Cloud Storage: is a cloud computing model that stores data on the Internet through a cloud computing provider who manages and operates data storage as a service. It's delivered on demand with just-in-time capacity and costs, and eliminates buying and managing your own data storage infrastructure. CDN: a content delivery network (CDN) refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content. Preparation Materials AWS API Gateway Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. APIs act as the "front door" for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications.
AWS DynamoDB Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second.
Dynamoose Dynamoose is a modeling tool for Amazon's DynamoDB. Dynamoose is heavily inspired by Mongoose, which means if you are coming from Mongoose the syntax will be very familar.
