*Application Integration* Flashcards
Amazon Simple Queue Service
Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.
Eliminates the complexity and overhead associated with managing and operating message oriented middleware, and empowers developers to focus on differentiating work.
You can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available.
AWS Step Functions
AWS Step Functions is a fully managed service that makes it easy to coordinate the components of distributed applications and microservices using visual workflows. Building applications from individual components that each perform a discrete function lets you scale easily and change applications quickly.
Step Functions is a reliable way to coordinate components and step through the functions of your
application.
- *Provides a graphical console to arrange and visualize the components of**
- *your application as a series of steps.** This makes it simple to build and run multi-step applications.
Automatically triggers and tracks each step, and retries when there are errors, so your application runs in order and as expected. Logs the state of each step, so when things do go wrong, you can diagnose and debug problems quickly. You can change and add steps without even writing code, so you can easily evolve your application and innovate faster.
Amazon Simple Workflow Service
Amazon Simple Workflow Service (Amazon SWF) helps developers build, run, and scale background jobs that have parallel or sequential steps. You can think of Amazon SWF as a fully-managed state tracker and task coordinator in the cloud. If your application’s steps take more than 500 milliseconds to complete, you need to track the state of processing. If you need to recover or retry if a task fails, Amazon SWF can help you.
Amazon Simple Notification Service
This service is a highly available, durable, secure, fully managed
pub/sub messaging service that enables you to decouple microservices, distributed systems, and
serverless applications.
This service provides topics for high-throughput, push-based, many-to-many
messaging. Fan out messages to a large number of subscriber endpoints for parallel processing, including Amazon SQS queues, AWS Lambda functions, and HTTP/S webhooks. Additionally, this service can be used to fan out notifications to end users using mobile push, SMS, and email.

Amazon AppFlow
Amazon AppFlow is a fully managed integration service that enables you to securely transfer data between Software-as-a-Service (SaaS) applications like Salesforce, Zendesk, Slack, and ServiceNow, and
AWS services like Amazon S3 and Amazon Redshift, in just a few clicks.
You can run data flows at enterprise scale at the frequency you choose - on a schedule, in response to a business event, or on demand.
You can configure data transformation capabilities like filtering and validation to
generate rich, ready-to-use data as part of the flow itself, without additional steps.
- *Automatically encrypts data in motion**, and allows users to restrict data from flowing over the public Internet for SaaS applications that are integrated with AWS PrivateLink, reducing exposure to security
- *threats.**
Amazon Managed Workflows for Apache Airflow
(MWAA)
Amazon Managed Workflows for Apache Airflow (MWAA) is a managed orchestration service for Apache Airflow that makes it easier to set up and operate end-to-end data pipelines in the cloud at scale.
Open-source tool used to programmatically author, schedule, and monitor sequences of processes and tasks referred to as “workflows.”
With Managed Workflows, you can use Airflow and Python to create workflows without having to manage the underlying infrastructure for scalability, availability, and security. Managed Workflows automatically scales its workflow execution capacity to meet your needs, and is integrated with AWS security services to help provide you with fast and secure access to data.
Amazon EventBridge
Amazon EventBridge is a serverless event bus that makes it easier to build event-driven applications at scale using events generated from your applications, integrated Software-as-a-Service (SaaS) applications, and AWS services.
Delivers a stream of real-time data from event sources such as Zendesk or Shopify to targets like AWS Lambda and other SaaS applications.
You can set up routing rules to determine where to send your data to build application architectures that react in real-time to your data sources with event publisher and consumer completely decoupled.
Amazon MQ
Amazon MQ is a managed message broker service for Apache ActiveMQ and RabbitMQ that makes it easy to set up and operate message brokers in the cloud.
- *Message brokers allow different software**
- *systems–often using different programming languages, and on different platforms–to communicate and exchange information.** Amazon MQ reduces your operational load by managing the provisioning, setup, and maintenance of ActiveMQ and RabbitMQ, popular open-source message brokers.
Connecting your current applications to Amazon MQ is easy because it uses industry-standard APIs and protocols for messaging, including JMS, NMS, AMQP, STOMP, MQTT, and WebSocket. Using standards means that in most cases, there’s no need to rewrite any messaging code when you migrate to AWS.
