It also shows network traffic flow from the Synthetics canary to the internal endpoint and other AWS services. Solution overview For internal endpoints on Amazon VPCīelow is a schematic of components for setting up a Synthetics canary to monitor an internal endpoint on Amazon VPC. You create a canary using CloudWatch Synthetics to monitor the internal endpoint.Part B: Monitoring the internal endpoint.Setup networking pre-requisites for internal endpoints running on your existing Amazon VPC or other VPC networks/firewall setups.(Optional) Create an internal endpoint to use in this exercise.Next, create and configure Synthetics canary to monitor the internal endpoint. ![]() First, ensure and create the resources required for an internal endpoint. There are two parts for setting up the Synthetics canary. The lifeline of many businesses relies on a range of internal tools and critical applications that are regularly used by the entire workforce within the company. From accounting, invoicing, health, payroll, Human Resources (HR) portals, Customer Relationship Management (CRM) systems, corporate email, collaboration tools, and so on, the list of applications your employees rely on is long! Continuously monitoring for changes in latency and availability for critical internal applications has a direct impact on increased productivity for your organization.Synthetic monitoring can simulate real use cases for detailed testing in a staging environment. In such a scenario, synthetic monitoring allows you to test the impact of changes to the application before the changes go live. It is not possible to gauge the performance of new features in a pre-production environment with limited or no real users.Using synthetic monitoring to generate traffic that mimics real user traffic to monitor internal APIs and being able to correlate with other parts of the application helps developers get to the root cause of the issue quickly and effectively. Because APIs run in the background of an application, and are not directly accessed by users, the concept of real-user API monitoring would not make much sense.You want to detect and correlate the internal or external failure the instant it occurs and fix it before your customers send in a complaint or file this issue with support. A failure in the underlying image microservice causes images to stop loading in the recommendations pane. Taking a simple example, recommendations, search, product listings and filtering options on a Bookstore app are powered by one or more underlying services. Many modern applications are built such that various elements on a single webpage are powered by different underlying microservices and stacks.Here’s why you should use synthetic monitoring to monitor internal endpoints in addition to public endpoints: How to configure Synthetic canaries inside your firewall including set up inside the Amazon Virtual Private Cloud (Amazon VPC).Why monitoring internal endpoints should be part of your user experience monitoring strategy. ![]() Continuously monitoring both internal and external endpoints using synthetic monitoring is vital to ensure smooth operations on a consistent basis. Microservices, APIs, or internal web tools inside a private network often power customer-facing websites and applications. Accessible only to authorized users, the network is shielded from external internet access and acts as an essential hub for communication, collaboration, and more. Today, organizations rely on an intranet, or a private network to securely run their business infrastructure. They can proactively monitor to discover these issues, react faster, and avoid high cost to business. With Synthetics canaries, developers no longer have to wait for accidental discovery of bugs, or until a frustrated customer calls in. In addition, Synthetics canaries can also monitor for broken links, or unauthorized content changes resulting from phishing, code injection, or cross-site scripting. Since Amazon CloudWatch Synthetics launched in 2019, Synthetics canaries have become the first line of defense to reliably alert developers if their public endpoints, including REST APIs and URLs, show unexpected latencies or availability drops. ![]()
