The complexity of such deployments has accelerated with the adoption of emerging, open-source technologies that generate telemetry data, which is exploding in terms of volume, speed, and cardinality. Extend your topology mapping to include open-source observability data.
The open-source scripting language PHP is used by over 78% of all websites that use a server-side programming language. Full context, including application dependencies, network topologies, and assessment of business risk based on vulnerabilities, exposures, and asset value are needed to manage enterprise-wide software risks.
Security vulnerabilities are weaknesses in applications, operating systems, networks, and other IT services and infrastructure that would allow an attacker to compromise a system, steal data, or otherwise disrupt IT operations. For example, an attacker could exploit a misconfigured firewall rule to gain access to servers on your network.
Introducing gnmi-gateway: a modular, distributed, and highly available service for modern network telemetry via OpenConfig and gNMI By: Colin McIntosh, Michael Costello Netflix runs its own content delivery network, Open Connect , which delivers all streaming traffic to our members.
Since December 10, days after a critical vulnerability known as Log4Shell was discovered in servers supporting the game Minecraft, millions of exploit attempts have been made of the Log4j 2 Java library, according to one team tracking the impact, with potential threat to millions more applications and devices across the globe. Dynatrace news.
When software runs in a monolithic stack on on-site servers, observability is manageable enough. OpenTelemetry, the opensource observability tool, has emerged as an industry-standard solution for instrumenting application telemetry data to make it observable. OpenTelemetry is a free and opensource take on observability.
Redis , short for Remote Dictionary Server, is a BSD-licensed, open-source in-memory key-value data structure store written in C language by Salvatore Sanfillipo and was first released on May 10, 2009.

To transport our ADS-B application’s JSON log files into our Dynatrace tenant, we’ll leverage an agentless approach using opensource software ( OpenTelemetry ).
But there is an opposite trend to use several layers of different frameworks and libraries which nobody fully understand and what is actually sent to the server remains unknown unless you use recording (or reconstruct it from a detailed log). Make scripting easier (and maintain the existing scripts) is utmost importance here.
There are certain situations when an agent based approach isn’t possible, such as with network or storage devices, or a very old OS. The Platform Extensions Services team is pleased to announce the opensourcing of our implementations for DNS lookups, port checks, and ping in GitHub. Platform extensions.
OpenTelemetry , the opensource observability tool, has become the go-to standard for instrumenting custom applications to collect observability telemetry data. This allows us to quickly tell whether the network link may be saturated or the processor is running at its limit. Hence it could detect, instrument, and monitor them.
A set of programming models has emerged to help developers define and train AI models with deep learning; along with opensource frameworks that put deep learning in the hands of mere mortals. Some examples of popular deep learning frameworks that we support on AWS include Caffe, CNTK, MXNet, TensorFlow, Theano, and Torch.
In response to this trend, opensource communities birthed new companies like WSO2 (of course, industry giants like Google, IBM, Software AG, and Tibco are also competing for a piece of the API management cake). Is it the WSO2-AM gateway itself, a networking issue, a sudden increase in demand, or something else entirely?
