Serverless is more than AWS Lambda

Too often serverless is equated with just AWS Lambda. Yes, it’s true: Amazon Web Services (AWS) helped to pioneer what is commonly referred to as serverless today with AWS Lambda, which was first announced back in 2015. But in 2020, it’s important for enterprises to understand that the serverless landscape is much bigger with more opportunities. Serverless is sometimes (narrowly) defined as just being about functions-as-a-service, but that’s a very limited viewpoint.

Essential Open Source Serverless Code Libraries

Serverless applications, due to their distributed nature, are often stuck having to reinvent the wheel. While small utility scripts and functions are often easily instrumented and monitored, anything of a transactional nature will need to implement special code to provide developers with common tools like stack traces, atomicity, and other patterns that rely on a singular flow of control.

Announcing Stackery-Native Provisioned Concurrency Support

The seamless scaling and headache-free reliability of a serverless application architecture has become compelling to a broad community of cloud specialists. But for those who have yet to become converts, a specific issue related to service startup latency—Cold Starts—has been one of the cited key objections. Fortunately, the serverless marketplace is maturing.

Send Custom HTML Email Notification with Power Automate Outlook Connector

Two years ago, I wrote a similar post on Microsoft Flow: How to pass the SQL data table results in a Markdown-formatted table into an Email notification or Approval Requests. It is still quite up to date, i.e., it is an excellent solution that you can still use today. The only problem with that article is that I was using “send an email” action in Power Automate Outlook connector that is currently deprecated.

Key metrics for monitoring AWS Lambda

AWS Lambda is a compute service that enables you to build serverless applications without the need to provision or maintain infrastructure resources (e.g., server capacity, network, security patches). AWS Lambda is event driven, meaning it triggers in response to events from other services, such as API calls from Amazon API Gateway or changes to a DynamoDB table.

Tools for collecting AWS Lambda data

In Part 1 of this series, we discussed AWS Lambda functions and some key metrics for monitoring them. In this post, we’ll look at using Amazon’s native tooling to query those metrics. We’ll also show you how to collect logs and traces that provide further visibility into your Lambda functions. Amazon provides built-in monitoring functionality through CloudWatch and X-Ray.

Monitoring AWS Lambda with Datadog

In Part 2 of this series, we looked at how Amazon’s built-in monitoring services can help you get insights into all of your AWS Lambda functions. In this post, we’ll show you how to use Datadog to monitor all of the metrics emitted by Lambda, as well as function logs and performance data, to get a complete picture of your serverless applications. In this post, we will: Datadog integrates with AWS Lambda and other services such as Amazon API Gateway, S3, and DynamoDB.
