Is a PDF a digital product?

A PDF (Portable Document Format) is indeed considered a digital product. It's a file format developed by Adobe that presents documents, including text formatting and images, in a manner independent of software, hardware, and operating systems. Here's an in-depth exploration of why PDFs qualify as digital products: What Constitutes a Digital Product? Digital Nature: A digital product exists solely in digital or electronic form. PDFs meet this criterion as they are electronic files created, viewed, and shared using digital devices. Intangible Asset: They lack a physical form and are intangible assets stored on computers, servers, or other digital storage mediums. Ease of Distribution: PDFs are easily distributed through the internet, email, or other digital means. They can be downloaded, shared, and accessed worldwide within seconds. Functional Value: PDFs provide various functionalities like text search, hyperlinking, multimedia integration, and password protection, en

Rule of Nine: Why 99.999% Availability in a World of Continuous Availability

Every business strives for excellence when it comes to application availability, but few achieve it.

Most availability solutions offer 99% - which might sound good for most organizations until you realize that 99% means 87.6 hours of unplanned downtime per year. Rendering to research by the Aberdeen Group, the average cost of downtime due to data loss for enterprises can be as high as $ 163,000 per hour. So, the rule of nine: For every nine that an IT team can achieve by increasing its availability, the more it can reduce downtime and improve system profitability. Let's take a look at how each additional “9” is achieved today and how it affects business performance.


99.9% is good business practice

There are many availability solutions that provide average results - for example, an x86 server can expect 99% availability if that's all your business needs. But with today's solutions, 99.9% availability is quite achievable. Affordable servers more influential than the average x86 server can be combined with redundant power supplies, fans, RAID, and of course, best business practices to maintain and protect your system.

Result?

99.9% means approximately 8.76 hours of unplanned downtime per year. That's a big improvement from nearly 90 hours of downtime by 99 percent, but for many companies, the lost productivity of one day per year is still too big for their bottom line.

99.99% high availability

The key to reaching the next “9” for 99.99% is cluster technology. Clusters, often referred to as high availability solutions, are essentially two or more physical servers connected on the same network. If one server fails, application support continues on the second server.

Clusters can have 99.99% to 99.99% availability, depending on the quality of the cluster and how quickly failover can be achieved. Some clustered applications, such as databases, cannot fail over quickly enough because they have to check file integrity and replay transaction logs after a failure, which delays application startup.

Fault tolerance ensures 99.999% availability

Now imagine that your company was able to add the most elusive number "9" to achieve 99.999% availability. What is needed for this? Fault-tolerant systems today deliver the Holy Grail of availability by addressing failures and continuing to function without disrupting applications, preventing any downtime due to system failure.

Resilient hardware solutions deliver 99.999% or better availability, which means less than five minutes of unplanned downtime per year. Software Fault Tolerance delivers similar results when using standard servers running in parallel, allowing one application to run on two virtual machines (VMs) at the same time. If one virtual machine crashes, the application will continue to run on the other virtual machine without any interruptions or data loss. Thus, virtualization offers the fifth 9.

However, not all fault-tolerant solutions are the same. Some emulate fault tolerance, but end up creating a lot of overhead that degrades performance. You need true fault tolerance to avoid performance issues and meet all your application requirements.

 99.999%: example

For nearly sixty years, Kaye Instruments has been at the forefront of high-precision process measurement in the biopharmaceutical industry, and its equipment has become the standard in high-precision measurement systems.

In pharmaceutical production, products are usually produced in very large batches, but in high volume production it is impossible to verify the quality of each abomination. That is why in the modern pharmaceutical world, quality must be taken into account directly in the design of the production process. If the builder does not have data to support continuous product monitoring, the product cannot be released.

Consequently, any downtime in these processes results in loss of income. This critical value for uptime and data integrity has led Kaye to trust Stratus as an integral part of their solutions. To learn more about how Kaye Instruments works with Stratus, watch the video below:
