Docker is a helpful tool for application management. You can use Docker in various ways: in the standalone mode, using Docker Compose on a single host, or by deploying containers and connecting Docker engines across multiple hosts. The user can use Docker containers with the default network, the host network, or other more advanced networks like overlays. This depends on the use case and/or the adopted technologies.

‍ The solution: We can use Sentry to track specific errors that occur on production and Hosted Graphite's Sentry webhook add-on to add annotations to our system performance graphs. This way, we can correlate when a specific error occurs with our system usage spikes. ‍ Sentry is an application that alerts you when an app gets an error. It can also alert you to specific mistakes so you can see when and where something broke.

This series will guide you through the most crucial container networking concepts. You don't need to be a Docker expert to comprehend the ideas introduced here, though a basic understanding of networking, Docker, and Kubernetes is required. Docker is a tool designed to create, build, and run isolated environments inside containers. It's widely used to containerize applications to run inside lightweight containers.

AWS Elastic Container Service for Kubernetes (EKS) is a managed service ideal for large clusters of nodes running heavy and variable workloads. Because of how account permissions work in AWS, EKS's architecture is unusual and creates slight differences in your monitoring strategy. Overall, it's still the same Kubernetes you know and love.

With the nearly unmatched reliability and scalability offered by the 12-factor application design pattern, microservice-based designs have become a fundamental architectural pattern for modern applications. A whole industry of cloud providers has sprung up to offer management of the sophisticated middleware and infrastructure services that make this possible. Amazon Web Services (AWS) is among the largest of them.

Apache Spark is a powerful tool for processing and analyzing large datasets quickly, whether you're cleaning data for a report, running machine learning models, or analyzing real-time data streams. It's widely used for everything from building big data pipelines to crunching numbers for advanced analytics, thanks to its speed and ability to scale across clusters.

Monitoring the health of your API endpoints is crucial to keeping your applications running smoothly and ensuring users have a reliable experience. Keeping an eye on 4XX and 5XX status codes can help you spot issues like client errors, misconfigurations, or server problems before they get out of hand. Plus, setting up alerts for when these errors spike allows you to react quickly, fix problems, and maintain a high-quality service that your users can count on.

As businesses migrate to the cloud, monitoring these environments becomes critically important. Digital Ocean is a popular developer choice due to its simplicity and scalability. However, effectively monitoring resources and applications within Digital Ocean can pose unique challenges. Hosted Graphite and Telegraf provide robust solutions for these challenges, allowing users to visualize data, track system metrics in real-time, and troubleshoot issues quickly.

Graphite and Splunk are data monitoring and visualization services with different pricing models. Graphite is open-source and free, while Splunk is a paid service with pricing starting at $225/month for Splunk Enterprise. Hosted Graphite is available at a starting price of $99/month. Choose based on specific needs and budget.
