Log centralization in microservices with Fluent Bit

Nowadays, it is quite common for systems to be made up of many subsystems. These include small programs that work together, full Operating Systems and proprietary applications. This growing number of subsystems needs maintenance to assess their performance, detect potential vulnerabilities and correct errors. One of the main tools IT professionals have to keep that many subsystems operational...

Overcoming entanglements without affecting developers

Last week’s article described the difficulties faced by developers when working with distributed and/or microservice architectures, often lacking in-depth knowledge about the underlying network technologies that enable different components of the architectures to communicate. As discussed, the main challenges relate to the way in which different services interact with each other rather than to...

The operational challenges of distributed software architecture

Microservice-based architectures are changing the way we design software today, raising new challenges in development and operations. These architectures are adding a strong network dependency on business logic, increasing the number of potential hazards, which grow proportionally to the connections or links that are created between services. Microservice vs monolithic architecture Monolithic...

Microservices, Dockers and Kubernetes

Many companies today are opting for microservices-based architecture. And this most certainly has to do with the fact that microservices are a perfect complement to SDN/SD-WAN technology, allowing the modules that make up the applications to be implanted in numerous servers or data centers. What is a microservice? The first aspect to note is that two types of application can be distinguished...

Uptime is down. Long live the fleeting!

Uptime is down. Long live the fleeting!

Since the early days of systems administration, a god has hovered over server rooms: uptime. uptime tells us how long a server has been on, which indirectly indicates how long it has been since it had a problem requiring a reboot. Operating systems have always had commands to display server uptime, figures that, indirectly, were also indicative of how good a job the administrators were doing....
