SpringBoot introduction to implementation principles
Spring framework is a powerful tool and fact standard for Java EE development, and Spring Boot simplifies the development of Spring by adopting the principle of “convention over configuration”, thus becoming the most popular micro-service development framework in the industry, which has been adopted by more and more enterprises. In March 2018, Spring Boot was officially upgraded from 1.x to 2.x. In order to adapt to the new trend, this article covers Spring Boot2.x technology in depth.

The MySQL database
MySQL feature
Written in C and C++, and using a variety of compilers for testing, to ensure the portability of source code
Support AIX, FreeBSD, HP-UX, Linux, MacOS, Novell Netware, OpenBSD, OS/2 Wrap, Solaris, Windows and other operating systems
Provides apis for a variety of programming languages. These languages include C, C++, Python, Java, Perl, PHP, Eiffel, Ruby, and Tcl.
Support multithreading, make full use of CPU resources
SQL query algorithm, effectively improve the query speed
It can not only be used as a single application in the client server network environment, but also be embedded in other software as a library to provide multi-language support. Common codes such as GB 2312 in Chinese, BIG5, Shift_JIS in Japanese, etc., can be used as data table names and data column names
Provides TCP/IP, ODBC, JDBC, and other database connections
Provides management tools for managing, checking, and optimizing database operations
Can handle large databases with tens of millions of records

Easy to understand Redis
Redis is a NoSQL database based on key-value pairs. Unlike many key-value pairs, The value in Redis can be composed of string, hash, list, set, zset, Bitmaps, HyperLogLog, GEO and other data structures and algorithms. So Redis can be used in many applications, and because Redis keeps all the data in memory, its read and write performance is amazing. In addition, Redis can save data in memory to hard disk in the form of snapshots and logs, so that data in memory is not “lost” in the event of power outages or machine failures. In addition to the above features, Redis also provides key expiration, publish and subscribe, transactions, pipelining, Lua scripting and other additional features. In short, if used in the right context, Redis can be as powerful as a Swiss Army knife.
The first part of getting started with Redis provides a basic introduction and shows some examples of how to use Redis.
The second core tutorial provides a detailed introduction to the commands of Redis, followed by an introduction to Redis management operations and ways to build more complex applications using Redis.

Nginx is easy to understand
Nginx is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP server. Nginx is characterized by low memory usage and high concurrency. In fact, NGINx’s concurrency does perform better in the same type of web server. Nginx can be compiled and run on most UnixLinux OS and is available for Windows ports. Nginx is a good alternative to Apache server for high concurrency connections. Nginx can either support Rails and PHP applications internally or as an HTTP proxy server. Written in C, Nginx is much more efficient in both system resource overhead and CPU usage than Perlbal. Nginx is a very simple server to install, with very clean configuration files (and perl syntax support) and very few bugs. Nginx is extremely easy to start and can run almost 24/7, even for months without a reboot. You can also upgrade software versions without interruption of service.

Docker of actual combat
A complete Docker consists of the following parts:
- DockerClient client
- Docker Daemon Daemon
- Docker Image mirror
- DockerContainer container
Docker is one of the fastest growing open source projects of all time, and the ecosystem around it is growing at a similar rate. For these reasons, the focus of the book is entirely on Docker’s toolset. This scope limitation can not only make content selection more accurate, but also help readers understand how to apply Docker features in their specific instances. Once readers have a firm grasp of the basics of the book, they can also tackle the bigger questions and explore the entire ecosystem.
