Transforming large amounts of data into formats that help solve business problems is what data engineers excel at. A combination of Serverless tools such as Athena, StepFunctions, Lambda, or Glue can get the job done in many projects. However, some customers prefer to rely on Open-Source projects and tools to access more talent in the job market and be less reliant on a single cloud provider. Today, we’ll share a story of a modernization project that we did for a customer in the online marketing industry.

I will show you how to implement pessimistic locking using Python with DynamoDB as our backend. Before we start, we’ll review the basics and discuss some of the design criteria we’re looking for. In an earlier post, I outlined to you how to implement optimistic locking using DynamoDB. There, I explained some of the reasons why locking is useful and which issues it can prevent. If you’re unfamiliar with the topic, I suggest you check that one out first.
Even when safely storing your MFA tokens using the Token2 Molto-2 device, some things are not quite optimal. You have to use special Windows-only software to program new accounts, it is not PIN-protected, and things could be better in terms of usability. If you have a bit more of a budget, the Reiner SCT tanJack Deluxe might solve your problems. Let’s have a look at this device.
The new agentless collector for the Application Discovery Service can be used to collect data from VMware vCenter and thus is useful whenever the ADS agent cannot be installed on the servers. However, AWS “forgot to mention” how to ensure connectivity over a proxy server in environments that do not allow direct internet access. Here`s how I fixed the issue.
In this article, we will install and deploy a circuit with a Bell State using AWS Braket SDK. Some minimal knowledge requirements are expected from the reader, namely concepts such as: Qubit, Superposition, Quantum Logical Gates (and a bit of math by association), Bell State, Python and perhaps AWS CLI.
SAP provides the SAP NetWeaver RFC SDK to allow external systems to call SAP Systems directly via SAP RFC. I will walk you through the steps it took me to deploy a function on AWS Lambda that uses the NW RFC SDK. Once you mastered those, you could use it to call any remote-enabled Function Module from AWS Lambda.
Everybody knows you should protect your AWS accounts (and other logins) with MFA against brute-force attacks. Most of the account providers use a standardized algorithm (RFC 6238) to generate the famous six-digit TOTP codes for your login. But where do you store those securely? Today, we will look at the alternatives and a specific device: The Molto-2.
I was searching for an AWS-native solution that would deploy resources via Terraform, allow them to do some work, and then destroy them properly without leaving any orphaned resources. Also, multiple of those Terraform deployments needed to be live at the same time. The solution I found is a combination of AWS CodeBuild, AWS Step Functions, a Terraform State being managed in S3 and Terraform Workspaces.
