Architecting Cloud Native Applications

By: Kamal Arora, Erik Farr, John Gilbert, Piyum Zonooz

Overview of this book

Cloud computing has proven to be the most revolutionary IT development since virtualization. Cloud native architectures give you the benefit of more flexibility over legacy systems. This Learning Path teaches you everything you need to know for designing industry-grade cloud applications and efficiently migrating your business to the cloud. It begins by exploring the basic patterns that turn your database inside out to achieve massive scalability. You’ll learn how to develop cloud native architectures using microservices and serverless computing as your design principles. Then, you’ll explore ways to continuously deliver production code by implementing continuous observability in production. In the concluding chapters, you’ll learn about various public cloud architectures ranging from AWS and Azure to the Google Cloud Platform, and understand the future trends and expectations of cloud providers. By the end of this Learning Path, you’ll have learned the techniques to adopt cloud native architectures that meet your business requirements. This Learning Path includes content from the following Packt products: • Cloud Native Development Patterns and Best Practices by John Gilbert • Cloud Native Architectures by Erik Farr et al.

CapEx versus OpEx


When building the business case for cloud, one of the most compelling arguments to senior leadership (read: C-suite) is the ability to shift IT spending from Capital Expenditures (CapEx) to Operational Expenditures (OpEx).

An operating expense is defined as the ongoing cost for running a business/system or providing a service/product.

There are several advantages that make up a compelling business case for leaders to transition to an OpEx model, which are enumerated as follows:

  • Lower, recurring costs versus large, upfront investments: As mentioned earlier in this chapter, building out a data center requires large amounts of time and resources to bring the compute power online. The cost associated with the time and resource allocation to building a data center is large. In an OpEx model, the business can achieve the same end result without...
