This is a hands-on course on how to deploy a fully Serverless web app using the AWS CDK. You can use the resources declared in this demo application as a starting point to mix and adapt to your own architectures later, which should save you quite some time.

A while back I talked about how big companies have started using serverless in production and how this is a clear sign that we will see more implementation of the serverless infrastructure in the near future. I’d like to take some time today and talk about one of the companies that are using serverless in production: Coca-cola.

Application Insights is used to monitor your live applications. It automatically detects performance anomalies. It also helps you to diagnose issues with the help of powerful analytics tools and to understand what users do with your app. The aim of development team is to help you understand how your app is performing and how it is being used by the customers.

When first looking into serverless migration and its architecture, it can feel like you’re staring down an endless shopping aisle of critical serverless tools that all need to be put into your basket straight away. Some services seem to offer the same function, while others can feel wildly different - both, as a result, can instill some doubts as to what is really necessary for your business and serverless application.

At Lumigo, we recently ran into some issues with a service we built on top of our Nodejs AWS Lambda handler. These issues were the result of lambda execution leaks from within our serverless code. In this article, I’ll explain about node.js lambda execution leaks and how to avoid them.

A while ago, we covered the invocation (trigger) methods supported by Lambda and the integrations available with the AWS catalog. Now we’re launching a series of articles to correlate these integration possibilities with common serverless architectural patterns (covered by this literature review). In Part I, we will cover the Orchestration & Aggregation category. Subscribe to our newsletter and stay tuned for the next parts of the series.

Information security (infosec) is a broad field. Its practitioners behave more like artists than engineers. After all, the mandate for security is not “do X”, but instead “ensure no one can do X, Y, Z, ɑ, β, ɣ, etc.”. The array of possibilities leading to infosec failure are vast. It’s like trying to prove a negative, thus making the task near impossible. On one hand we have an impossible task, on the other we have the affordance of time.

While we know the many benefits of going serverless - reduced costs via pay-per-use pricing models, less operational burden/overhead, instant scalability, increased automation - the challenges are often not addressed as comprehensively. The understandable concerns over migrating can stop any architectural decisions and actions being made for fear of getting it wrong and not having the right resources.

Applications have traditionally been run on servers, which have to be closely monitored to ensure there are no hindrances in production. In the case of serverless computing, you no longer have to manage servers, as the onus falls on cloud service providers. Read along to discover more about serverless computing, including some of its advantages and disadvantages. So what actually is serverless computing?
