Cloud Computing Trends

What this chapter covers

Cloud Computing Trends is 4% of the Huawei HCIA-Cloud Computing H13-511 exam. It covers OpenStack, the open source cloud platform, and the job of each of its core projects, plus emerging technologies such as containers, Kubernetes, edge computing and serverless at concept level.

Questions are single-answer, multiple-answer without a stated count, true/false, drag and drop and typed fill-in-the-blank, often "Which of the following statements is true?". This exam has no exhibit figures, so questions usually match an OpenStack project to its job or ask which statement about a new technology is correct.

It has 2 outline topics, and one page covers them.

How the topics fit together

Virtualization pools the resources of a few servers. OpenStack turns such pools into a self service cloud, and the emerging technologies change how applications are packaged and where they run.

Each step hides more of the infrastructure from the user, from servers to VMs to containers to single functions.

How to use these pages

Each topic page has the same shape, so you can skim for what you need.

• What it is: the idea in plain words.
• How it works: the mechanism, with tables and examples.
• What to remember for the exam: the facts to memorize.
• Common mistakes: the classic traps.
• Check yourself: three questions to test your understanding.

Read each component table and say what each row does before reading the explanation. The exam often names a component or feature and asks which job it performs.
