Taloflow Founder Presents at Vancouver AWS Meetup on Driving AWS Infrastructure Insights into Kafka

Last week, our CTO, Todd Kesselman, presented on "Driving AWS Infrastructure Insights into Kafka" in downtown Vancouver, Canada. In his presentation, he revealed an unobtrusive way to share a wide range of operational information between organizations in a way that can easily be incorporated into your event pipeline. The featured technology is the AWS Event Bus. To clarify, the Event Bus is a message bus that enables multiple AWS accounts to publish and receive events to and from each other.

Intel's latest security vulnerability - our steps and yours

This week Intel released a statement regarding Microarchitectural Data Sampling (MDS), another vulnerability in the "speculative execution" feature of modern processors. This is for HyperThreading and is the feature that allows the CPU to work out what commands will be run next, if they would affect the current running command and if not, run it on the same core.

Lambda and Kinesis - beware of hot streams

Back in 2017, I wrote a post titled “3 pro tips for Developers working with Kinesis streams”, in which I explained why you should avoid hot streams with many Lambda subscribers. When you have five or more functions subscribed to a Kinesis stream you will start to notice lots of ReadProvisionedThroughputExceeded errors in CloudWatch.

SLO, SLA, SLI Oh My! Creating them can be easy

Imagine you are driving a car on a freeway. Your speedometer is telling you you’re going 62 mph. But you “gotta go fast”. Faster than then 65 mph speed limit. So you go for it: first 68mph, then 75mph, then 80mph. Then you pass a police officer hiding in a speed trap. To your dismay, they pull you over and give you a ticket. All is not lost: there is a silver lining here.

AKS Cluster Performance: How to Better Operate Kubernetes in Azure

AKS is the managed service from Azure for Kubernetes. When you create an AKS cluster, Azure creates and operates the Kubernetes control plane for you at no cost. The only thing you do as a user is to say how many worker nodes you’d like, plus other configurations we’ll see in this post. So, with that in mind, how can you improve the AKS cluster performance of a service in which Azure pretty much manages almost everything?

Chef automation for infrastructure management

Infrastructure management has come a long way. (Mostly) gone are the days of manual configurations and deployments, when using SSH in a “for” loop was a perfectly reasonable way to execute server changes. Automation is a way of life. Configuration management tools like Chef, Puppet, and Ansible — once on the bleeding edge — are now used by most enterprises.

Historical data analytics with Logz.io

Have you ever found yourself trying to reconstruct an event from the past only to come up blank because you cannot go so far back in time? If only you could bring back that missing piece of the puzzle! In the world of IT, logs are the way machines and software record events. They help us understand when an event happened, where they happened and most importantly, why they happened.
