Discover the critical importance of monitoring API performance and resilience. Learn best practices and practical strategies to ensure business continuity and user satisfaction.
APIs (Application Programming Interfaces) have quietly evolved into the backbone of contemporary business operations, even though it's ironic that most people use APIs without even realizing it. For instance, you're ordering your favorite takeaway online; you tap the payment button, and voilà! Through APIs, your payment information swiftly traverses the digital landscape, promptly reflecting the adjustment in your credit card balance.
From ride-sharing apps to e-commerce platforms, APIs are the driving force behind the digital transformation revolutionizing how we interact with technology. However, the current API-heavy architectural approach has resulted in a reliance on intricate multi-step transactions and third-party API integrations, making the system more complex and interconnected. In this installment of our IPM Best Practices Series, we’ll explore how organizations can monitor APIs effectively to ensure resilience and user satisfaction.
This diagram depicts the basic steps in a typical online sneaker purchase. What the shopper does not see is everything that happens in the background, making this transaction look highly straightforward. Even before the shopper encounters the UI, a series of steps is initiated, beginning with DNS and progressing to fetching content from the server. APIs take center stage as they interact with the UI, bridging the gap between the front-end and targeted services. Initiating a shoe search triggers the search service, which checks the database to see if the sneakers are in stock. Simultaneously, inventory service requests provide additional information, like colors, sizes, and cost.
The modern consumer expects all of this to occur in the time it takes to blink. What happens, though, when something goes wrong?
Depending on the context and the nature of the application, API failure can have several catastrophic impacts on users, including functional disruption, data inaccuracies, loss of features, delayed updates, and security concerns.
If a third-party search widget on your e-commerce site fails, your customers cannot browse through your store. So, right from the outset, user experience is severely compromised, leading to frustrated customers who’ll likely abandon their transaction and try out the competition.
If the API call is responsible for fetching or updating data, an unresponsive API call can result in outdated or incorrect information being displayed to the user. Think of the potential impact of zip or postal code lookups becoming unresponsive on a ride-hailing app - the angry customers, the load on customer support, the outrage on Twitter.
If the APIs connecting to your payment gateways fail, you lose both customers and revenue, not to mention the impact on security. As APIs carry business-critical information, the loss of data integrity and security vulnerabilities become significant concerns, leaving your organization susceptible to cyber-attacks and data breaches.
Failure to address API issues promptly can have dire repercussions on business continuity and overall success. Monitoring APIs and ensuring their responsiveness thus becomes a critical consideration for businesses seeking to integrate them into their infrastructure.
The challenge is that APIs function within intricate webs of third-party dependencies, dynamic architectures, and microservice meshes, which often exceed the capabilities of traditional monitoring tools. The growing adoption of GraphQL APIs further amplifies this challenge. GraphQL's core flexibility empowers clients to request specific fields and nested data structures. While this adaptability is beneficial, it can complicate predicting the precise format and size of incoming requests.
To ensure performant APIs, businesses must make room for an API monitoring phase in their API Lifecycle to improve performance. Consistent monitoring helps keep uptime high and outage rates low across all applications and services. Below are some essential API monitoring best practices:
The stakes are high when it comes to API performance and resilience. Traditional monitoring can't keep up with the complex services behind our digital experiences. Catchpoint can help you ensure the resilience of your business-critical APIs with an Internet Performance Monitoring (IPM) approach that goes beyond traditional APM. Now enhanced by end-to-end Tracing capabilities, our IPM platform offers true end-to-end management and visibility of distributed applications, spanning from the user's experience all the way to the backend. With tools designed to proactively manage API incidents, your teams can reduce and even avoid the impact on end-users, enhancing overall service delivery.
