Overview of this book

As cloud applications are becoming more complex, multiple tools and services have emerged to cater to the challenges of running reliable solutions. Although infrastructure as code, containers, and orchestration tools, such as Kubernetes, have proved to be efficient in solving these challenges, AWS CDK represents a paradigm shift in building easily developed, extended, and maintained applications. With AWS CDK in Practice, you’ll start by setting up basic day-to-day infrastructure while understanding the new prospects that CDK offers. You’ll learn how to set up pipelines for building CDK applications on the cloud that are long-lasting, agile, and maintainable. You’ll also gain practical knowledge of container-based and serverless application development. Furthermore, you’ll discover how to leverage AWS CDK to build cloud solutions using code instead of configuration files. Finally, you’ll explore current community best practices for solving production issues when dealing with CDK applications. By the end of this book, you’ll have practical knowledge of CDK, and you’ll be able to leverage the power of AWS with code that is simple to write and maintain using AWS CDK.

Challenges with ISAA

Given the serverless nature of ISAA, whatever challenges serverless currently has and will be found to have in the future are automatically inherited by ISAA.

Runaway costs

One of the challenges with building indestructible serverless applications is the potential for runaway costs. Because serverless architectures rely on paying for usage, it can be easy to accidentally spin up a large number of resources or have a function that runs too frequently, leading to unexpected and potentially large bills.

However, there are several ways to mitigate this risk and keep costs under control. One approach is to use monitoring and analytics tools to track usage and identify areas where costs can be reduced. For example, you can use services such as AWS CloudWatch or AWS Cost Explorer to track the number of invocations and the duration of your functions and use this information to optimize their performance. Additionally, you can set up alerts to notify you when your...
