Application Development Using Microservices & Serverless complete course is currently being offered by IBM through Coursera platform and is taught by: Alex Parker.
About this Course!
Are you a developer ready to explore serverless application development? This intermediate-level course is for you!
Begin with an understanding of how serverless benefits developers, learn when to use serverless programming, serverless deployment models, and discover its top use cases and design patterns. You’ll also discover how serverless supports continuous integration and continuous delivery (CI/CD) and microservices integration.
Hands-on labs reinforce serverless programming concepts for creation, deployment, and invocation of cloud-based functions—including the deployment of microservices using OpenShift and Istio. Complete the course with the confidence to build a multi-tier web app that uses IBM Cloud Functions, OpenShift, Istio, and more.

FaaS
Question 10) A sequence is a chain of actions that are invoked in order. Why are actions invoked in order?
Output of one action is passed as input to the next action
Graded Quiz: ORM: MicroServices w/ Serverless
Question 1) After creating an action, you must invoke the action so it can do its task. What are two modes for invoking actions?
Blocking and non-blocking
Question 2) What can you use to pass parameters to actions?
A JSON file and the param-file flag.
Question 3) What do you use to create sequence actions?
Existing actions
Question 4) IBM Cloud Functions provides pre-installed libraries to call actions from other actions.
True
Question 5) What is provided by public packages for IBM Cloud Functions?
Actions
Triggers feeds
Question 6) What command can you use to avoid passing the same parameters to an action every time?
ibmcloud fn package bind
Question 7) How can you set default parameters for all entities in a package?
Set package level parameters that are inherited by all actions
Question 8) What can you use to configure an external event source to fire multiple trigger events?
Feed
Question 9) If you have already created an action and want to create a trigger to invoke this action, what three options must you include in the rule create command?
Name of rule, trigger, and action
Question 10) Why would you expose actions as APIs rather than manually via command line or web console?
Actions called manually don't integrate well with microservices
