Understanding Serverless Cost Models When evaluating your options for hosting and operating your software, cost is usu‐ ally a key consideration. In recent years, serverless has emerged as a sound choice for teams and organizations looking for simplicity and cost-efficiency. With the com‐ bination of managed services and a pay-per-use pricing model, there is huge […]

Software Architecture You’ve already learned a great deal about serverless architectures, patterns, develop‐ ment, and operating practices in this book. In this section, we’ll explore how they are relevant to promoting sustainability in the cloud by looking at some best practices. A decoupled event-driven serverless application composed of man‐ aged cloud services is a step […]

Classification of data and tagging. As part of the solution design for your serverless application, it is a good practice to recognize the data classifications and designate appropriate tags. You can classify data in your enterprise in several ways, depending on the context—sensitivity, shareability, secrecy, durability, etc. If you classify data based on durability, for […]

Total Cost of Ownership in the Cloud Your monthly bill shows you the obvious, regular cost of running your serverless application in the cloud. There is, however, another cost: the cost of ownership. Total cost of ownership (TCO) is an established concept that helps organizations understand the cost of software over time, not just at […]

Compute Costs Serverless compute using AWS Lambda will typically be widespread in your server‐ less architecture. It is one of the most important cost models to understand when you are getting started, as it probably differs the most from what you are familiar with. Compute Will Cost Less Than You Expect What may surprise you […]

Avoiding Serverless Cost Gotchas In the next section, we’ll explore the tools and techniques available for estimating serverless costs. However, the cost of a serverless application that is distributed across many managed services, interacting constantly as traffic flows into and through your system, can be difficult to predict. These more obscure costs can be seen […]

Serverless Cost Estimation Now that you know how much some of the popular serverless services cost, it’s time to figure out how to estimate costs for your own operations. Cost estimation can be a very useful exercise, especially when designing new serverless applications or microservices and evaluating architectural options. However, it can be difficult to […]

Reducing the Operational Cost of Serverless Due to the use of multiple interconnected managed services in a serverless applica‐ tion, cost is intrinsically linked to architecture. Excessive and expensive usage of a service or direct integration usually indicates architectural inefficiencies. If you’re doing something expensive, there is probably a better way to do it! A […]
