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. Existing function instances can be closed at any time without 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-run photo editing servies ning 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.  serverless functionality works the same way it does with other applications and is an easy option for databases. You can configure the connection to your database change the application to connect to your instance instead of the database and the connection will be pooled and then further configuration can be done between and database this has the ability.



To keep serverless functionality stateless and focus on serving the business Logic added bonus. The diagram shows the pooling of many database connections through separate service proxies before connecting to the database. Options also exist for other database engines such as . This hosting solution enables you to bring in your own database and add other features on top of it. Note that some are incompatible with database agents. Be sure to check your library's documentation to determine which option is right for you. Bringing Your Computing to the Edge Now that your serverless functions are protected from scaling out of control, let’s take a look at edge computing first and foremost. While edge environments and serverless deployments can exist independently, in this article we’ll look specifically .
