Building applications using serverless technology on AWS—like AWS Lambda and Amazon API Gateway—can be incredibly powerful. You get to scale effortlessly and focus on writing code without worrying about managing servers. But as your application grows and spreads across hundreds or even thousands of cloud resources, keeping track of errors and fixing issues quickly becomes a big challenge.

Your frontline workers need AI, and they need it now. They need guidance. They need information. And it’s getting harder to find a co-worker or manager that can provide these things. Everyone’s busy. In fact, in Zebra’s latest Global Shopper Study, 85% of the retail associates surveyed said they believe AI will help them be more productive, and 78% said AI/machine learning would boost efficiency and customer service. Three-quarters said the same for generative AI (GenAI).

In separate incidents this past month, I’ve helped clients troubleshoot network problems that turned out to be due to misconfigured switches. In all cases, the errors turned out to be things that I don’t think should ever have been changed from their default settings. So I thought it might be useful to have a brief discussion about how switches work and what features should or should not be used in normal office environments.

Network access control (NAC) is a critical component of any organization’s cybersecurity strategy. As companies adopt increasingly flexible work environments and emerging technologies like the Internet of Things (IoT), their networks have expanded rapidly. More users, devices, and access points mean more potential vulnerabilities that attackers could exploit. Implementing NAC solutions lets organizations stay securely connected despite relying on a complex, dynamic infrastructure.
