What Is Load Balancing? Load balancing is the process of dividing the traffic on the network across multiple servers through a tool known as the load balancer. This tool acts like a router directing the inbound traffic on different servers as and when required. However, unlike a router making the decision to route traffic based…

ogging is essential for understanding what’s happening within your running code. Furthermore, you can use log data to track various metrics such as HTTP error rates, failed login attempts, and overall application availability. That’s not all, though. Log aggregation platforms allow for log analysis and the creation of advanced alerting mechanisms to detect anomalies. For example, a…

I need to learn this. I get that feeling from time to time. Maybe you have experienced it too. For me, it happens when I know there is a better way to do things and I feel there isn’t enough time to stop and learn. It actually happened a few weeks ago. We have a large…

Test Driven Development (TDD) is not only a discipline we like to write about, we practice it ourselves every day. This is a blog post we shared with our friends over at Rainforest QA. Because we know you can’t enough of a good thing, we’re re-posting it here. Enjoy! Librato is a prolific engineering shop….

Why You Need Server Monitoring Monitoring plays a crucial role in any IT environment. It notifies you when things go wrong and provides a general idea of the health and capacity of your infrastructure. But monitoring can also play a more proactive role. If done correctly, monitoring can find the root cause of an issue…

Python applications have proven to be top notch when dealing with complex scientific or numeric problems. As Python applications become more dynamic and complex, there’s a need to monitor performance for better troubleshooting. Developers would want to monitor Python performance for several reasons. For instance, you’d want to be the first to notice any likelihood…

Amazon CloudWatch is a popular option for collecting system and performance metrics from your AWS resources.  For some services, it’s the only means available to collect badly needed metrics data. CloudWatch makes it trivially easy to fetch core system metrics like CPU, Network, and Disk, as well as more specialized metrics like queue-sizes and latency…

Have you ever needed to quickly set up a web server? Or have you been required to distribute a load among many nodes? In these situations, the solution is often NGINX. NGINX can perform both functions, as it’s a web server but can also work as a load balancer, an HTTP cache, or even an…

Django is a web framework used in a wide variety of websites. It just takes a quick web search to discover which large companies use it as a production platform.

Monitoring user-facing software has always been important, no doubt about it. But with the unrelenting migration of software to the cloud, and the adoption of microservices and serverless architectures such as Function as a Service (FaaS), monitoring is now business-critical. These new ways of building modern software involve many moving parts, and developers need to…

While everyone knows application monitoring is an essential part of running awesome software services, understanding whether you need application performance management (APM) or log management isn’t so straightforward. Both techniques involve collecting data that describe your application’s behavior, and both help you analyze that data. Despite the similarities between APM and log management, they serve…
