Microservices are a software engineering and architecture methodology in which the software is composed of de-coupled componentized services that communicate via well-defined interfaces over an API.

What are Microservices?

A K-Sortable Unique IDentifier (KSUID), is an alternative uniquely generated identifier from the GUID, UUID, and ULID. KSUIDs are generated with the goal of being loosely sorted by generation time.

QR codes are a type of barcode. QR Code contain various forms of information encoded in the pattern. Information encoded in a QR Code's pattern can include website urls, links, account information, phone numbers, or even coupons. Any information typed into the input will be encoded into the QR Code.

Add the following to the custom section of your Serverless YAML file:

We've now created a custom AWS VPC in in the us-east region with VPC Endpoint Interfaces for 6 other AWS Services. VPC Endpoint Interfaces allow services in your VPC to interact with the specified resources:

You can deploy other AWS CloudFormation Stack services into the same VPC by adding the following to the other Stack's Serverless file:

Configure and deploy a custom AWS VPC using your Serverless YAML template. The VPC can be reference in other AWS CloudFormation Stacks by automatically output variables.

Microservices architectures allow applications to scale, grow, pivot, and innovate much more efficiently than other architectures.

What’s the difference: Monolithic v Microservices

Monolithic architectures typically indicate that all processes are tightly coupled and can only run as a single service and usually on that same server. Expanding the codebase and product offering becomes increasingly complicated dues to the inter woven functionality. Monolithic applications need to have an indepth infrastructure monitoring &amp; maintenance and DevOps plans in place to keep access and performance stable and the application grows.

Microservices architecture designs allow an application to be built with independent components that run each application process individually as its own service. Services communicate via a well-defined interface through a, typically internal, API layer. Microservice services are built for business capabilities by taking into account the needed business logic and each service performs an individual function or logically grouped functionalities. Since they are independently run, services can be individually updated, deployed, reverted, and scaled to meet current and future demand of an application.

JavaScript Object Notation (JSON) is a lightweight, text-based, language-independent data interchange format. It was derived from the ECMAScript Programming Language Standard. JSON defines a small set of formatting rules for the portable representation of structured data.

JavaScript Object Notation (JSON) is a text format for the serialization of structured data. It is derived from the object literals of JavaScript, as defined in the ECMA Script Programming Language Standard, Third Edition [ECMA]. JSON can represent four primitive types (strings, numbers, booleans, and null) and two structured types (objects and arrays). A string is a sequence of zero or more Unicode characters [UNICODE]. An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array. An array is an ordered sequence of zero or more values. The terms “object” and “array” come from the conventions of JavaScript. JSON’s design goals were for it to be minimal, portable, textual, and a subset of JavaScript.

The MIME media type for JSON text is application/json.
