Chapter 18. BEST PRACTICES IN ARCHITECTING CLOUD APPLICATIONS IN THE AWS CLOUD

JINESH VARIA

INTRODUCTION

For several years, software architects have discovered and implemented several concepts and best practices to build highly scalable applications. In today's "era of tera," these concepts are even more applicable because of ever-growing datasets, unpredictable traffic patterns, and the demand for faster response times. This chapter will reinforce and reiterate some of these traditional concepts and discuss how they may evolve in the context of cloud computing. It will also discuss some unprecedented concepts, such as elasticity, that have emerged due to the dynamic nature of the cloud.
