In today's world, the need for highly available and fault-tolerant systems is more important than ever. Furthermore, with the increased adoption of microservices and containerization , the need for a reliable infrastructure that can automatically detect and recover from failures has become critical. Kubernetes , an open-source container orchestration platform, and Prometheus, a popular monitoring and alerting toolkit, are two tools that can be used to implement such a self-healing infrastructure

With the launch of ChatGPT, an AI chatbot developed by OpenAI, in November 2022, large language models (LLMs) and generative AI have become a global sensation, making their way to the top of boardroom agendas and household discussions worldwide. GPT (generative pre-trained transformer) technology and the LLM-based AI systems that drive it have huge implications and potential advantages for many tasks, from improving customer service to increasing employee productivity.

I have seen many Linux Performance engineers looking at the “IOWait” portion of CPU usage as something to indicate whenever the system is I/O-bound. In this blog post, I will explain why this approach is unreliable and what better indicators you can use. Let’s start by running a little experiment – generating heavy I/O usage on the system: sysbench --threads=8 --time=0 --max-requests=0 fileio --file-num=1 --file-total-size=10G --file-io-mode=sync --file-extra-flags=direct

Log forensics—investigating security incidents based on log data—has become more challenging as organizations adopt cloud-native technologies. Organizations are increasingly turning to these cloud environments to stay competitive, remain agile, and grow. But as organizations rely more on cloud environments, data and complexity have proliferated. Teams struggle to maintain control of and gain visibility into all the applications, microservices and data dependencies these environments generate.

Historically MySQL is great in horizontal READ scale. The scaling, in that case, is offered by the different number of Replica nodes, no matter if using standard asynchronous replication or synchronous replication. However, those solutions do not offer the same level of scaling for writes operation. Why? Because the solutions still rely on writing in one single node that works as Primary.

Kubernetes has become the de facto standard for container orchestration, enabling organizations to build, deploy, and scale modern applications with efficiency and agility. As more organizations adopt Kubernetes, the need for proper security and management of sensitive data within these environments becomes paramount. One crucial aspect of ensuring a secure Kubernetes infrastructure is the effective management of secrets, such as API keys, passwords, and tokens.

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process.

At the same time that I see database engineers relying on the tool, sites such as StackOverflow are banning ChatGPT.

It’s hard to ignore the discussion around the Open Letter arguing for a pause in the development of advanced AI systems. Are they dangerous? Will they destroy humanity? Will they condemn all but a few of us to boring, impoverished lives? If these are indeed the dangers we face, pausing AI development for six months is certainly a weak and ineffective preventive.

For cloud operations teams, network performance monitoring is central in ensuring application and infrastructure performance. If the network is sluggish, an application may also be slow, frustrating users. Worse, a malicious attacker may gain access to the network, compromising sensitive application data. Still, despite having adopted myriad network monitoring tools, organizations still struggle to identify whether the network is at fault for application and infrastructure problems.

As a database administrator, have you ever been in a situation when your database confronted a brute force attack? A brute force attack can be launched against a user account in MySQL. MySQL replies with success or error based on supplied credentials, and the time required for the verification is almost the same in either case. Hence, an attacker can launch a brute force attack against a MySQL user account at a rapid rate and can try many different passwords.

The ultimate state for any team is self-determination: they lead their own discovery of work, self-prioritize that work, self-organize their roles and self-direct the delivery. Self-determination requires meta awareness. The team knows the problem space - the motivations of different actors (buyers, users, influencers), the guiding policies (regulatory and commercial preference), the tech in place, and so forth.

But as the number of microservices increased and application pods are distributed across multiple clusters and cloud providers, managing and scaling them has become complex. While scaling, it is harder to configure complex communication logic between microservices.
