BrandPost: Wi-Fi Location-based Services: How Did We Get Here?

By: Dorothy Stanley, Fellow and Head, Wireless Standards Strategy, Aruba, a Hewlett Packard Enterprise company.Wi-Fi systems are so ubiquitous indoors that location-based services are a natural extension. Retail analytics, indoor navigation, and high-value asset tracking (such as medical devices in health care) are a just a few of the use cases that organizations are deploying using Wi-Fi location-based services to improve business outcomes. In this post, I’ll delve into the evolution of Wi-Fi location-based services and give you a preview of where the standards are taking us and how your organization can take advantage of them.To read this article in full, please click here

  • Installation guidance: Understand key considerations prior to your deployment of Red Hat Ansible Automation Platform.

  • Monitoring your Ansible Automation Platform: Learn how to use Prometheus and Grafana to monitor your Ansible Continue reading

Modernizing the WAN from Client to Cloud

Modernizing the WAN from Client to Cloud

The evolution of WAN architectures has historically paralleled that of application architectures. When we primarily connected terminals to mainframes, the WAN architecture was largely point-to-point links connecting back to data center facilities. As traffic converged to remove OpEx-intensive parallel network structures, the WAN evolved to architectures that enabled site-to-site connectivity in a full mesh or configurable mesh and then enabled multi-tenancy for carrier cost optimization.

External Links on Spine Switches

A networking engineer attending the Building Next-Generation Data Center online course asked this question:

What is the best practice to connect DC fabric to outside world assuming there are 2 spine switches in the fabric and EVPN VXLAN is used as overlay? Is it a good idea to introduce edge (border) switches, or it is better to connect outside world directly to the spine?

As always, the answer is “it depends,” this time based on:

SD-WAN, SASE prove essential tools for Porsche’s electric-racecar success

The ninth season of Formula E World Championship racing is under way, with events slated this spring everywhere from Berlin to Jakarta to Portland, Oregon. Formula E has all of the thrills and spills of IndyCar or F1 racing—sleek aerodynamic vehicles, talented drivers, spirited competition. But there’s one key difference: the cars are electric.In traditional auto racing, the skills of the driver are certainly important, but so is the strategy of when to make a pit stop for fuel and tires as well as the real-time communication between driver and pit crew. Similarly, in Formula E the driver is the star of the show, but data analytics running in the background plays an important role.To read this article in full, please click here

Assume Disaster

One of the things that people have mentioned to me in the past regarding my event management skills is my reaction time. They say, “You are always on top of things when they go wrong. How do you do it?”

My response never fails to make them laugh. I offer, “I always assume something is going to go wrong. I may not know what it is but when it does happen I’m ready to fix it.”

That may sound like a cynical take on planning and operations but it’s served me well for many years. Why is it that things we spend so much time working on always seem to go off the rails?

Complexity Fails

Whether it’s an event or a network or even a carpentry project you have to assume that something is going to go wrong. Why? Because the more complex the project the more likely you are to hit a snag. Systems that build on themselves and require input to proceed are notorious for hitting blocks that cause the whole thing to snarl into a mess of missed timelines.

When I was in college studying project management I learned there’s even a term for Continue reading

Providing Terraform with that Ansible Magic

ansible terraform magic blog

Late last year, we introduced a Red Hat Ansible Certified Collection Collection for Terraform. This was an important step in automation, as these two tools really are great together and leveraging Ansible's ability to orchestrate other tools in the enterprise made this a no-brainer. Terraform with its infrastructure as code (IaC) provisioning and Ansible’s strength in configuration as code are a synergy that cannot be ignored - we are better together! Organizations are now in the position to utilize their existing infrastructure as code manifests and extend their automation with Terraform and Ansible together.  

Now, we are back  with help from our partners at Kyndryl and XLAB and adding more value and magic to infrastructure as code - This time we have some extra muscle with an addition to the Red Hat Ansible Certified Content Collection: The Ansible provider for Terraform.

So what does the provider help us with?

Without a provider, we would need to rely on inventory plugins for the different cloud platforms and use filters to grab instance information from our freshly "Terraformed" infrastructure. This allows us to update our inventory so we can run automated tasks against these hosts. This is pretty smooth in Continue reading

JWTs: Connecting the Dots: Why, When and How

JSON web tokens (JWTs) are great — they are easy to work with and stateless, requiring less communication with a centralized authentication server. JWTs are handy when you need to securely pass information between services. As such, they’re often used as ID tokens or access tokens. This is generally considered a secure practice as the tokens are usually signed and encrypted. However, when incorrectly configured or misused, JWTs can lead to broken object-level authorization or broken function-level authorization vulnerabilities. These vulnerabilities can expose a state where users can access other data or endpoints beyond their privileges. Therefore, it’s vital to follow best practices for using JWTs. Knowing and understanding the fundamentals of JWTs is essential when determining a behavior strategy. Curity is a leading IAM and API security technology provider that enables user authentication and authorization for digital services.
