    At their core, microservices<\/span><\/strong> are a response to the monolithic applications<\/span> of yesteryear. Rather than designing apps<\/span> as one massive entity that is so interconnected there is no such thing as a small problem anymore, microservices<\/span> instead break even the most complicated apps<\/span> down into a series of individual and independently deployable parts.<\/p>\n\n\n\n

    The benefit<\/strong> here is that not only can smaller and more specifically focused teams<\/span> take control over their own services, but you also don’t have to wait for “everything” to be done before getting your app<\/span> into the hands of end users<\/span>. You can roll out functionality as it is finished<\/strong>, trusting that it will eventually add up to that larger “whole” you were building in the first place.<\/p>\n\n\n\n

    But at the same time, simply buying into the microservices architecture alone isn’t enough to guarantee success. You’ll still need to monitor your microservices<\/span> on a regular basis<\/strong> – something that is important for a wide array of different reasons, all of which are more than worth exploring.<\/p>\n\n\n\n

    What is Health Monitoring?<\/h2>\n\n\n\n

    Generally speaking, health monitoring with regards to microservices<\/span><\/strong> is exactly what it sounds like: the process<\/span> of using<\/span> an application performance monitoring<\/a> or related tool<\/span> to gain better insight into all key areas of your app<\/span> and its performance<\/span>, allowing you to make better and more informed decisions<\/span> as development goes on.<\/p>\n\n\n\n

    Really, it’s about gaining a much-needed level of visibility into not only how your application<\/span> is functioning as a whole, but how each microservice<\/span> is doing individually and how they all relate to one another and empower<\/span> one another to become something far more important as a collective than they could be individually.<\/p>\n\n\n\n
