Applications to serverless and edge deployments can be trickier than it seems. In this article we'll take a deep dive into common challenges and potential solutions faced by developers deploying applications to staging environments. Table of Contents A Note on Terminology Serverless Deployments and Your Common Serverless Disadvantages Avoiding Serverless Headaches Taking Your Computing to the Edge Edge Computing Considerations Up A Note on Terminology We will be talking a lot about serverless and edge deployments. While the definitions of these technologies are not set in stone, we have a good primer on these technologies and how we think about them. In a nutshell serverless will be shorthand for stateless functions as a service offering while edge will refer to any way developers can bring business logic closer to end users. Serverless deployments and function-as-a-service offerings have become increasingly popular ways to deploy.
Data-driven workloads. Serverless deployments increase scalability and reduce costs while not requiring developers to make extensive changes in their day-to-day photo editing servies work. Having said that, while serverless deployments offer compelling advantages, they also come with specific challenges. You may find some difficulty in introducing stateful behavior into a stateless environment when you need to connect to a persistent data store. Let’s take a closer look at how to effectively leverage serverless capabilities while avoiding common pitfalls. Common Serverless Disadvantages Regardless of the underlying runtime differences, all serverless functions face the same challenges. They are ephemeral deployments In a non-serverless environment this function will not have any impact on performance but in a serverless environment without some protection this function can cause severe damage to your application and your wallet. For example if usage of this.
Existing function instances can be closed at any time and new instances can be created without knowledge of previous processing. This is very detrimental to services that need to access non-temporary data stores. For example, consider what would happen if a function was turned off during a transaction. A scaling strategy caused ten thousand new functions to be connected to the database. A long-running query or multiple queries made the function call take longer than average. When developing applications for a serverless environment it is always important to assume that such issues can and will occur. Avoiding Serverless Headaches To illustrate how the problem arises let’s look at a simple example. Below is a simple handler which accepts a query in the database for an item and then returns the result object.
