What is serverless Monitoring?

Serverless computing is a cloud-based computing approach where the cloud provider operates the server and allocates machine resources dynamically. The use of serverless computing can speed up innovation and lower operational costs. In summary, serverless monitoring tools enable administrators to keep track of their apps and services.

AWS uses backend infrastructure and networks to create serverless offerings. When you hear the term serverless, it does not indicate that you don’t need to supply your server for hosting; it simply means you aren’t required to provide a server. Using a serverless monitoring solution is the best way to minimize expenses and improve the performance of your apps.

Overall, you need a solution to monitor serverless applications across different functionalities and create accurate data without affecting the application’s functionality or speed. We’ll take a look at some of the most effective serverless monitoring tools available nowadays.

Why do we need “Serverless monitoring”?

  • Serverless monitoring enables your systems to provide data that you may use to understand how they work. Many essential parameters, such as latency, prices, resource utilization, and cold starts, maybe tracked using serverless monitoring tools.
  • A competent serverless monitoring tool will spot application failures in real-time and route them to the appropriate channel. Unfortunately, you’ll find that it’s not easy to keep track of your serverless architecture, as it has a proprietary character that prevents you from knowing too much about the underlying code.

Challenges associated with serverless monitoring

Let’s talk about the common errors that people encounter when using serverless and how to avoid them. New adopters frequently face concerns with control, security, architectural complexity, and monitoring and testing. Let’s take them one by one and see how we can best solve their obstacles.

Loss of Control

An issue with serverless is the loss of control. So, what? In serverless applications, we often integrate third-party managed services (BaaS—backend as a service) and function platforms (FaaS—functions as a service). Third-party developers and operators run these BaaS and FaaS.

In a non-serverless world, we take over the entire stack, including which software versions go into each service. Then we write queues and databases. We lose control as we migrate to serverless because we no longer own the software stack our services run on. The good news is that we can devote more time and energy to providing business value.


A risk evaluation is essential if you are worried about losing control of your infrastructure. This can help you assess what matters most to your company and how losing control might impact it. Using a third-party authentication system provides the same (if not more) value as creating your own. Remember that if you write a system yourself, you must own and maintain it for its entire life.


Poorly configured applications are a significant serverless danger. Poor configuration can lead to many problems, including security ones. For example, if you use AWS, you must correctly configure your services’ rights to access other AWS services. A function, for example, may be granted more privileges than it needs, allowing for a security violation. In addition, since cloud security mechanisms cannot be transmitted outside the cloud, we must ensure that any HTTP connections to third-party services are secure and the data is encrypted.


The most important thing is to provide your AWS resources with the correct permissions so they can do their jobs. Give your functions the exact permissions they require and provide them with strict permissions. Then encrypt all your data at rest. Additionally, ensure that third-party connections are made through a secure connection.

Architecture Complexity

Even the most straightforward serverless application has a complex architecture diagram. Generally, function code is short and does just one thing, leading to many functions per application. We also employ managed services for several tasks. Combining these two factors tends to complicate architecture. The architectural level of an application’s complexity is then increased. You must follow solid architectural patterns, or you will end up with complicated architecture.


The simplest method for preventing architectural complexity is to learn distributed system design. Understand how to construct event-driven apps using the most prevalent architectural patterns and understand how to use asynchronous messaging to add extra features to your applications. In a distributed system, asynchronous messaging is more efficient than synchronous messaging. It is critical to understand how services interact, how latency affects requests, and where bottlenecks exist. Changing the architecture can sometimes increase the performance of all programs.

Difficult to Test

Serverless apps are difficult to test due to their distributed nature. Developers prefer local testing because they were used to it before serverless was accessible. However, local tests are complicated in the serverless era since we need to imitate cloud services locally. One of the significant hazards in non-serverless apps is in the code. Configurations and integrations are the most significant dangers in serverless apps. So we must also execute a sufficient number of integration tests.


Finding a suitable monitoring tool that works for your application is critical to overcoming monitoring challenges. There are several unique features. Having a monitoring service that supports the ELK Stack, visualizes the various logs and metrics (from resources and functions), and provides distributed tracing is widely regarded as the industry standard. In addition, the most advanced tools will already have serverless integrations like Lambda.

Difficult to Monitor

Our system is challenging to monitor for the same reasons it is difficult to test. The tools and methods of tracking serverless apps are still a long way from perfection. Such a task is far more complicated than expected. Unlike traditional applications, where we only monitor code execution, serverless apps require us to monitor service integrations and ensure that we can track a request from start to finish in our distributed system.


To overcome the challenges of testing serverless apps, it is critical to properly build your application to unit-test the business logic and create cloud integration tests.
