The latest News and Information on Serverless Monitoring, Management, Development and related cloud technologies.
As businesses embrace cloud-native application development as a basis for modernization, the shift creates significant security challenges. D2iQ has partnered with Aqua Security to enable organizations to create a seamless DevSecOps experience that accelerates the deployment of secure smart cloud-native applications to prevent and foil cloud-native cyber attacks.
As a developer, Python for me is a heavy-lifting and versatile language. I’ve used it for building APIs, internet of things projects, file and data conversions, machine learning and (of course) web development. Like with any modern, commonly used language, the functionality behind the application is only as good as the infrastructure that it is deployed onto.
It’s no secret that application containerization has revolutionized the digital world as we know it by providing a transient gateway into elastic infrastructure that can scale and grow as needed. Where traditional virtualization was all about creating a single homogenous entity, containers are self-contained units of software, able to run in just about any environment, making them extremely portable.
You’ve probably seen Rush Hour, a logic puzzle where you have to slide cars and trucks out of the way to steer the red car towards the exit. In real life, when your customers are responsible for tracking hundreds or thousands of data points from dozens of valuable, mission-critical sensors, you’re tracking engine speed, network signal level, distance from the RF, and more—and not just through traffic but across continents.
When building systems that need to scale above a certain number of users, we usually can’t stay on one machine. This is where cloud providers like AWS usually come into play. They allow us to rent VMs or containers for small intervals. This way, we can start a few different machines when more traffic hits, and when it goes down later, we can simply turn off our extra capacity and save money. The question is, how does all this traffic get to our new machines? AWS Elastic Load Balancing!
The combination of SNS to SQS to Lambda is a common sight in serverless applications on AWS. Perhaps triggered by messages from an API function. This architecture is great for improving UX by offloading slow, asynchronous tasks so the API can stay responsive. It presents an interesting challenge for observability, however. Because observability tools are not able to trace invocations through this combination end-to-end. In X-Ray, for example, the trace would stop at SNS.
