Nonrelational databases In a nonrelational database, you create tables. A table is a place where you can store and query data. Nonrelational databases are sometimes referred to as “NoSQL databases” because they use structures other than rows and columns to organize data. One type of structural approach for nonrelational databases is key-value pairs. With key-value pairs, data is organized into i..

Relational databases In a relational database, data is stored in a way that relates it to other pieces of data. An example of a relational database might be the coffee shop’s inventory management system. Each record in the database would include data for a single item, such as product name, size, price, and so on. Relational databases use structured query language (SQL) to store and query data. ..

File storage In file storage, multiple clients (such as users, applications, servers, and so on) can access data that is stored in shared file folders. In this approach, a storage server uses block storage with a local file system to organize files. Clients access data through file paths. Compared to block storage and object storage, file storage is ideal for use cases in which a large number of..

Object storage In object storage, each object consists of data, metadata, and a key. The data might be an image, video, text document, or any other type of file. Metadata contains information about what the data is, how it is used, the object size, and so on. An object’s key is its unique identifier. Recall that when you modify a file in block storage, only the pieces that are changed are update..

Instance stores Block-level storage volumes behave like physical hard drives. An instance store provides temporary block-level storage for an Amazon EC2 instance. An instance store is disk storage that is physically attached to the host computer for an EC2 instance and therefore has the same lifespan as the instance. When the instance is terminated, you lose any data in the instance store. Amazo..

AWS - Invoke Local This runs your code locally by emulating the AWS Lambda environment. Please keep in mind, it's not a 100% perfect emulation, there may be some differences, but it works for the vast majority of users. We mock the context with simple mock data.

Domain Name System (DNS) Suppose that a Company has a website hosted in the AWS Cloud. Customers enter the web address into their browser, and they are able to access the website. This happens because of Domain Name System (DNS) resolution. DNS resolution involves a customer DNS resolver communicating with a company DNS server. You can think of DNS as being the phone book of the internet. DNS re..
