This tutorial is the first in a series of tutorials on virtual private cloud, and it walks you through the deployment of a bastion host to securely access remote instances within a virtual private cloud.
When building applications, one has to factor failures into the design. An application may fail because of a bug in the code. The underlying infrastructure running the application can fail, whether it is a bare metal server or a virtual machine. The network connectivity can fail intermittently. A datacenter may lose power and the backup generator may not start either. That's already a lot of risks to cover and to protect from.
Developers do not like to write the same thing twice. The DRY principle is one example of this. Similarly they don't like having to go through tons of clicks in a user interface to setup an environment. Consequently shell scripts have been long used by system administrators and developers to automate repetitive, error-prone and uninteresting tasks.

Serverless computing platforms give developers a rapid way to build APIs without servers. OpenWhisk supports automatic generation of REST API for actions exposed by API Gateway. When the capabilities provided by the API Gateway do not cover all usecases you have for an API - such as publishing it in a developer portal or performing advanced mapping, transformation, validation, you can migrate to the API Connect service.
