In the evening on September 30, people across Cuba found their internet service cut. The residents of this Caribbean nation had begun protesting their government’s tepid response to Hurricane Ian which had wrought destruction a week earlier. Internet service returned to normal the following morning, but this outage wasn’t caused by storm-related damage. This blackout was a deliberate act, a fact confirmed when service dropped out for the same period of time the following day.

The main street in my town is mostly lined with mom-and-pop shops, and I love to support these businesses. Large online retailers keep making it harder for these stores to compete, so I think it’s important to keep doing business with them when I can. Lately, it’s been interesting to see that these mom-and-pop shops increasingly have something in common with the largest online retailers: They’re reliant on the internet to deliver their goods and services to consumers.

The drive for faster, more scalable services is on the rise. Our day-to-day lives depend on apps, from a food delivery app to have your favorite meal delivered, to your banking app to manage your accounts, to even apps to schedule doctor’s appointments. These apps need to be able to grow from not only a features standpoint but also in terms of user capacity. The scale and need for global reach drives increasing complexity for these high-demand cloud applications.

Understand the two dimensions of scaling for database query and ingest workloads, and how sharding can make scaling elastic — or not. Scaling throughput and performance are critical design topics for all distributed databases, and sharding is usually a part of the solution. However, a design that increases throughput does not always help with performance and vice versa. Even when a design supports both, scaling them up and down at the same time is not always easy.

Without an online presence, running a business is no longer possible. You can't rely on only social media to reach out to people and provide all information related to your business. From products, descriptions, prices, and functioning hours. People look for everything online. If you have products or services, you need at least a small business website to let people know what you deal with. It surely helps you provide a market, reach more customers, and gain popularity in just a short period.

Digital Employee Experience (DEX) is grossly understated in today’s corporate landscape, despite the growing interest in digital transformation in companies everywhere. Technology has long been central to the workplace, but not enough effort has been put into the experience of those who use it. Enterprises, especially global enterprises, can spend upward of tens of thousands of dollars on software and digital appliances to make work easier for their team.

When interacting with the Icinga 2 API, the client is commonly authenticated using a password provided via HTTP basic auth. Icinga 2 also support a second authentication mechanism: TLS client certificates. This is a feature of TLS that also allows the client to send a certificate, just like the server does, allowing the server to authenticate the client as well.

Understand how to calculate the composite reliability of your cloud infrastructure to help design Cloud architectures with an optimal SLA.

One of the building blocks of messaging is, you guessed it, messages! But there are different kinds of messages: Commands and Events. So, what’s the difference? Well, they have very distinct purposes, usage, naming, ownership, and more!

For organizations of all types and sizes, networks are more than just a line item on a departmental budget. Modern digital enterprises understand that long-term competitiveness depends on maximizing their IT assets to create exceptional user experiences.
