Serverless architectures are redefining application development and management. More than just an advancement, this type of architecture challenges monitoring and observability strategies; after all, maintaining solution stability requires a close and meticulous eye on the vital indicators of applications.  

However, while the serverless model offers numerous competitive advantages, we must not forget that it also involves some challenges, such as constant monitoring, to ensure that applications run efficiently, securely, and cost-effectively.

The good news is that AWS also offers serverless monitoring services that can assist your organization. 

Want to know the best practices and tools offered by AWS to monitor your applications, ensuring a detailed and informative view? Then, read on!

What does the term “Serverless” mean?

As the name implies, serverless is a computing model where the cloud provider itself automatically manages the allocation, provisioning, maintenance, and scaling of resources. 

Highly beneficial for businesses, within this structure, developers only need to package their code into containers to deploy it. 

In addition, they only pay for the execution time of the code, eliminating the need to constantly provision and manage servers.

How does serverless monitoring work?

In practice, serverless monitoring solutions integrate data and information from the entire application structure, providing detailed statistics on resource usage to generate logs and metrics. 

These solutions allow managers and developers to visualize the activities of serverless functions, track feature usage, and set up automated alerts to gain critical insights.

Through monitoring dashboards, it is possible to eliminate blind spots, ensure complete visibility of the application, and avoid unmonitored areas that could hide issues. 

Another advantage is that these dashboards enable the measurement of function integrity, evaluating performance and identifying failures and anomalous behaviors. 

Memory utilization is also closely monitored, allowing tracking of consumption to ensure functions operate within allocated limits, avoiding negative impacts on application performance and availability. 

With these tools, it is possible to identify bottlenecks, make constant adjustments, and perform optimizations to improve the overall efficiency and performance of the serverless architecture.

Why is it important to monitor serverless architectures?

In serverless architectures, monitoring is essential. This is because, além de allowing the early detection of issues capable of impacting application performance and availability, the practice also detects problems such as high response time, execution failures, and excessive resource consumption.

Another advantage is that monitoring effectively contributes to cost reduction. Considering that serverless architectures charge based on resource usage, it is a fact that a misconfigured or inefficient application can generate unnecessary expenses. 

To prevent wasting time and resources, monitoring tools assist in identifying opportunities for performance optimization, helping to enable a more cost-effective and efficient operation.

Last but not least, monitoring is fundamental for security. After all, by monitoring metrics and logs, it is possible to observe suspicious or unusual activities more quickly, ensuring redoubled protection against potential threats.
