Write at the front-5 minutes a day to play with OpenStack (1)

"5 minutes a day with OpenStack" is an OpenStack tutorial, this is the 1th article.

This tutorial has the following two features:

2. The system explains OpenStack
   From the architecture to the individual components, from the whole to the detailed discussion

4. re-practice and take into account theory
   Mainly from the actual operation of the point of view with everyone learning OpenStack.

Why do you write this?

The simple answer is: because OpenStack learning is difficult, but if you know the value will be very big

Let's start with a self-introduction.

I network name Cloudman, in it this business has been in the past more than 10 years, 05 is to engage in the development of the upper application, Java compared to fire, so the related technology of the EE more. Later into a large IT company, the company's products from the middleware to the operating system, from server to storage, virtualization to cloud computing are involved.

My department is dedicated to the implementation of IT infrastructure services, the project involves servers, storage, networking, virtualization, cloud aspects. And the important task of this department is to expand the company in the latest and hottest areas of the IT market. such as the previous years of virtualization, the two years of cloud computing and big data.

It can be said that this position in the department is very much in line with my technical preference. I have a long-term interest in new technology and learning enthusiasm, so in this department is more than 10 years, and has been engaged in technology, although now the title is an architect, usually still insist on actual hands-on operation, otherwise there will be no sense of security.

Okay, now go back to the OpenStack topic.

I began to contact OpenStack in 2013, although with relatively solid technical skills, after a period of study, or feel OpenStack this thing is not easy to get started, personally think there are several reasons:

2. The knowledge areas covered by OpenStack are very wide  
   

4. OpenStack is a platform, not a concrete embodiment
   openstack uses driver architecture to support a variety of specific implementation technologies. For example, OpenStack storage service Cinder only defines the upper-level abstract API, the implementation of the following Driver, such as the LVM-based iSCSI DRIVER,EMC, IBM and other commercial storage products Driver, or open-source distributed storage software, such as Ceph, Glusterfs's driver.
   because of this architectural flexibility, Makes it easier for beginners to learn openstack than to learn other specific software products.

6. OpenStack itself is a distributed system
   Most of IT are not too familiar with distributed computing. Rushing in directly will be foggy by the myriad of OpenStack components and the way they interact with each other.

Although the OpenStack learning curve is steeper, it's not as big as it is, but OpenStack is now a reality standard for IaaS clouds, and the future is bright enough for us to engage it if we can chew on this bone, it will definitely improve our competitiveness.

Write to WHO to see

The target audience for this tutorial includes:

2. OpenStack beginner  
   cloudman Learning OpenStack has also experienced a difficult and tortuous process. The main reason for this is that no system has been found to teach OpenStack tutorials, especially for beginners. Most of the information is more scattered, for beginners can not be organically strung together. It was for this reason that I had the idea of writing a tutorial that would allow beginners to learn, master, and practice OpenStack with less detours.

4. OpenStack implementation Engineer  
   

6. my own
   Writing this tutorial is also a summary of your own years of learning and practicing OpenStack.
   I think: for knowledge, only to write it and to be able to make other people understand to really know that they have mastered this knowledge.

What is included in the content?

For example, two chunks:

2. Preparatory knowledge
   

4. OpenStack Core
   This is the main content, including the architecture of OpenStack and the various core components. There will be a number of cases, procedures, and logs to help you understand how OpenStack components work.
   
   

What kind of writing method?

In the current era of shared economy, Cloudman felt that the Internet should be used to share knowledge and experience. This tutorial will be published regularly via Cloudman's public number (CLOUDMAN6), 1, 3, 5 per week.

I think there are two benefits of using the public number:

1. View and browse what you've pushed, anytime, anywhere
2. Can interact with Cloudman through the public number and ask questions and suggestions

Why is it called " 5 minutes a day to play OpenStack?

in order to reduce the difficulty of learning and take into account the characteristics of mobile fragmented reading, each push content only need to spend 5 minutes to finish the (note that this is read Sometimes it takes more time to fully understand, Each time the content contains only 1-3 knowledge points, which is why I named the tutorial "5 minutes a day to play with OpenStack". Although it is fragmented push, the whole tutorial is systematic, coherent and complete, just piecemeal.

OK, today this 5 minutes is a start, next time we formally started to play with OpenStack.
