NiFi as a Function in DataFlow Service provides an efficient, cost optimized, scalable way to run NiFi flows in a completely serverless fashion. Functions as a Service (FaaS) is a category of cloud computing services that all main cloud providers are offering (AWS Lambda, Azure Functions, Google Cloud Functions, etc).
Since it was an isolated feature, we created a separate Lambda function for it on AWS. Serverless architecture usually requires expertise in event-driven programming, microservices, and a deep understanding of the enterprise cloud ecosystem. Are you comfortable with higher OpEx for lower CapEx? Is vendor lock-in a major concern?
AWS Step Functions is a fully managed service that makes it easier to coordinate the components of distributed applications and microservices using visual workflows. Building applications from individual components that each perform a discrete function helps you scale more easily and change applications more quickly.
And microservice-composition is much more interesting when you don’t have to worry about scaling. Once you introduce microservices, the kind of problems you’re chasing are simpler. and the actual application services; in this case, a Lambda Function. tenant context, role, etc) Custom authorizer Lambda.
Observability came out of microservices and cloud-native, right? On both counts—yeah, it sorta came out of microservices and cloud native, and yeah sorta, you need it with a simpler architecture (though perhaps not as desperately as you otherwise might). The need for observability grew forth from microservices and cloud native.
Given that it is at a relatively early stage, developers are still trying to grok the best approach for each cloud vendor and often face the following question: Should I go cloud native with AWS Lambda, GCP functions, etc., or invest in a vendor-agnostic layer like the serverless framework ?
microservices, containers, orchestrators?—?require This tool provides a CLI and Docker-based replication of a production serverless environment in order to enable the efficient local development of AWS Lambda functions that use associated AWS services such as Amazon API Gateway and DynamoDB. require new developer workflow patterns.
A “Traditional” Microservice Architecture for a Catalog It wasn’t that long ago that we were talking about decomposing monoliths into microservices (in fact we still are!). Cognito Security as a Service hosted by Amazon that ties in neatly with IAM and allows us to login and permission users in a granular fashion.
Developers have plenty of choices for their serverless solutions today: AWS Lambda, Google Cloud Functions, Microsoft Azure Functions and Cloudflare Workers. As an AWS Select Partner, we at Modus are big fans of AWS Lambda and their many serverless managed solutions. For this post, we’ll mainly focus on AWS Lambda.
Trendy, fashionable things are often a flash in the pan, forgotten or regretted a year or two later (like Pet Rocks or Chia Pets ). New frameworks appear every day (literally), and our corporate clients won’t suddenly tell their staff to reimplement the ecommerce site just because last year’s hot framework is no longer fashionable.
