Getting Started with Amazon EventBridge

By -
Amazon EventBridge is a serverless event bus service that makes it easy to detect and react to state changes in AWS services, application and custom applications. EventBridge constantly monitors your resources and applications for changes or events, such as a new log file being created, a new blistering CPU usage alarm going off, an IP address change in your VPC and more. EventBridge routes these events to targets such as AWS Lambda functions, Kinesis data streams, step functions or any other supported event targets. 
EventBridge allows you to build event-driven applications without having to manage the underlying infrastructure required to connect all the components. You define rules that specify which events get sent to which targets. When those events occur, EventBridge invokes the associated targets. Rules can combine multiple event sources to be sent to a single target, or split event patterns across multiple targets.

Some key capabilities of Amazon EventBridge include:

- Event monitoring - Built-in integration with many AWS services like EC2, DynamoDB, S3 etc to detect changes and events from resources. You can also publish custom events.

- Event routing - Route events to different targets like Lambda functions, step functions, Kinesis data streams etc for event-driven processing. Supports routing to both synchronous and asynchronous targets. 

- Event transformation - Transform raw event data before delivering to targets using helper functions like JSONPath template. 

- Access control - Granular IAM permissions to control which resources, events and targets applications can access. 

- Event scheduling - Schedule regular or cron-based events like runs of Lambda functions and APIs. 

- Reliable delivery - Uses a publish-subscribe model with at-least-once delivery and dead-letter queues for failed events.

This introductory post gave an overview of Amazon EventBridge and how it can help build event-driven applications on AWS in a serverless way. EventBridge makes it easy to react to changes across various AWS services and applications by monitoring for events and routing them to appropriate targets for processing.

Getting Started with Amazon Athena

By -

Amazon Athena is an interactive query service that makes it easy to analyze data directly in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. With Athena, data analysts, scientists, and developers can directly query datasets stored in Amazon S3 to gain insights without having to load the data into databases or maintain databases. Athena allows you to analyze large datasets in Amazon S3 using standard SQL. With just a few clicks in the AWS Management Console, you can point Athena at your data stored in S3 buckets and start querying it using standard SQL. You don't need to set up any infrastructure or load your data into databases. You pay per query with no setup costs. Athena scales automatically—running queries on petabytes of data is as easy as querying gigabytes of data. It's even integrated with business intelligence (BI) tools like Tableau, QuickSight, and Microsoft Power...

Getting Started with AWS Config

AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. It allows you to view configuration history, detect unauthorized configuration changes, and evaluate your resources' compliance against rules and best practices. AWS Config continuously monitors and records configuration changes to your AWS resources. This allows you to understand their relationships and how they are configured over time.  With AWS Config, you can enable recording of configuration changes for supported resource types like EC2 instances, S3 buckets, Lambda functions, and more. It will build a configuration history for each of your resources. You can then write rules to evaluate if a resource is compliant or non-compliant based on certain configurations. For example, you could write a rule to detect if a S3 bucket doesn't have versioning enabled. AWS Config will then evaluate all your S3 buckets and report any that don't meet the requirement. Some key b...

AWS Identity and Access Management (IAM)

AWS Identity and Access Management (IAM) allows you to securely control access to AWS services and resources for your users. With IAM, you can create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources. IAM allows you to control who in your organization has access to which AWS services and resources. IAM is a feature of AWS that allows you to create users and groups within your AWS account, assign permissions to those users and groups, and use credentials to allow and deny access to resources like EC2 instances, S3 buckets, Lambda functions and more. With IAM you can centrally manage users, security credentials like access keys, and permissions to help ensure secure access to AWS resources.  When you first create an AWS account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. Using IAM, you can add additional users to your AWS account, without having to ...
