Looking down and looking up at the sky, let's jump out of the details and take a look at the nature of micro-services. Veteran brother thinks: micro-service is a better division of labor and cooperation mechanism, accelerate the division of labor, promote cooperation, and help us achieve greater dreams! Why? Please take a look at my experience in the process of promoting micro-service architecture in recent years!

Driven by the wave of cloud computing technology, various industries have accelerated the pace of digital transformation. Micro-service, as a recommended architecture for cloud native applications, is no stranger to every practitioner in the IT industry. Everyone has heard a lot about the advantages of micro-service architecture, what key components are included in a typical micro-service architecture, and what are the mainstream micro-service framework products in the industry. After seeing so much and knowing so much, there will be a lot of exclamation marks and question marks: do you want to introduce a micro-service architecture? Where should such a complex technology stack start? Gradual evolution or one step at a time?

These questions make us hesitate at the intersection. Should we go left or right? The cloud native technology stack belongs to the category of applied science. If we find the internal driving force to adopt these technologies and take some time to study and practice, everyone can master this technology stack. After all, applying technology is not difficult for us. The crux of the problem is to find the reason to persuade and move yourself. In the past two years, I have been thinking about this question in the process of promoting the micro-service architecture, and how to help customers find the internal driving force to adopt the new architecture. Now sort out these answers for your reference, hoping to help you find a reason to fall in love with micro-services!

As shown in the table below, compared with the monolithic architecture, the microservice architecture has many advantages, but it is also accompanied by many new questions. In the case of stalemate between advantages and disadvantages, it is difficult for us to decide whether to adopt this new technology stack. Since we can't make up our mind according to the specific comparative analysis, can we jump out of the question and explore the answer? Just like in the process of walking through the forest, there are several forks in front of you, opportunities and risks coexist, and if you don't know where each road will take us, any choice is an adventure. At this point, we need to climb the highland, or the top of the mountain or the crown of trees, to find out the direction of each road, so that we can choose the right path and do our best. Next, let's explore the nature of microservices. What kind of architectural development trend lies behind it?

In 2014, Yuval Herari, a cutting-edge Israeli historian, published a book, A brief History of Man: from Animals to God, which was very popular. In the book, the author analyzes the process of our human evolution from monkeys to creatures step by step. On earth, human civilization is the most advanced. Compared with other species, we are like the Creator. We can build anything we want, or we can change the living environment as we wish. Why not other species, but only humans? Because only humans can dream, that is, we will fantasize about and pursue things that do not already exist, while other species will only have enough to eat and sleep.

Dreams are usually impractical, and there are challenges to realize them. The bigger the dream, the more people need to participate. People are nurtured by water and land, and everyone has different characteristics. Dream, will have different strengths of people together to work hard, this is the dream team. Dream, division of labor and cooperation are the underlying mechanisms to promote the continuous development of human civilization. Human dreams are getting bigger and bigger, from human cloning to silicon-based intelligence; the social division of labor is becoming more and more elaborate, from farmers and workers to thousands of occupations now; and teamwork is becoming more and more extensive. From cooperation between a few people to cooperation across oceans and continents.

Taking the human "flying dream" as an example, we can easily verify this mechanism. " Look how beautiful the star is, take off one and give it to you. "as the lyrics say, maybe our dream of flying comes from the pursuit of love, or from the desire for freedom, to break free from the shackles of gravity, from flying by kite, to traveling around the world in hot air balloons, to the invention of airplanes by the Wright brothers, to the birth of supersonic jets, and then to the advent of Musk's SpaceX colonizing Mars. And the imagination of science fiction writer Liu Cixin to take the earth to travel, this is the process of human beings surpassing their dreams, but what does it have to do with a finer division of labor and more extensive cooperation?

The Airbus A380, the largest airliner in history, recently announced that it had stopped production. The Airbus A380 is the product of bringing together the most cutting-edge technology in various countries of the European Union, each country has its own specialized field of science and technology, but now it is impossible to continue cooperation because of the disintegration of the European Union. Without the division of labor and cooperation, the dream will not last. The topic has gone so far, what does it have to do with the theme of our article? Micro-service, a new architecture technology, before exploring the nature of micro-service, it is necessary to define the architecture: architecture is the highest level of system decomposition and the decision that the system is not easy to change. it mainly describes the core components of the system, the relationship between components (that is, communication paths, mechanisms and expected results), and key processes (how components interact to complete a business) and so on.

In short, architecture is the mechanism for standardizing the division of labor and cooperation. Divide the components so that they have unique functions and perform their own duties, which is the division of labor; standardize the communication mechanism between components, exchange of needed goods, this is cooperation. Engaged in application architecture or system architecture and other positions, we need to understand the characteristics of a variety of mainstream middleware, software and hardware equipment, in order to make a reasonable division of labor. At the same time, we also need to know how to choose the right products to meet the needs in specific business scenarios, so that they can work closely together. With this understanding, we can understand various types of architecture, such as changes in organizational structure.

Now we know that the essence of micro-service is: a better division of labor and cooperation mechanism, accelerate the division of labor, promote cooperation, and help us achieve greater dreams! OK, that's all for today, and the veteran will continue to tell this story about dreams, division of labor and cooperation:

Why should we introduce a micro-service architecture? Why do microservices start with the separation of front and rear ends? How to gradually evolve to a full micro-service architecture? What are the key steps in microservice implementation? Which systems are suitable for transformation into micro-services?
