In the previous chapters, we discussed the high availability of networks. This chapter will continue with the high availability theme and discuss how to make our applications that are running in the cloud highly available. We will also take a look at how to distribute traffic among a set of instances serving the same content through load balancing by taking a look at the AWS Elastic Load Balancing (ELB) service.
