+<p>Let's start the journey of microservice with a simple <strong>Body Mass 
Index(BMI)</strong> application. The <a 
href="https://en.wikipedia.org/wiki/Body_mass_index"; target="_blank">BMI</a> is 
an attempt to quantify the amount of tissue mass in an individual. This 
application contains two separate microservices:</p>
+
+<ul>
+  <li>
+    <p><strong>BMI calculator service</strong>:A microservice provides 
calculation of BMI.</p>
+  </li>
+  <li>
+    <p><strong>Web service</strong>:A microservice provides both user 
interface and gateway service.</p>
+  </li>
+</ul>
+
+<p>The workflow of the application is shown as follows:<br />
+<img src="/assets/images/quick-start-sample-workflow-en.png" alt="workflow of

+        <h2 id="overview">Overview</h2>
+<p>SecKill is a demo project that our ServiceComb team try to build a 
micro-service architecture from the perspective of domain-driven design (<a 
href="https://en.wikipedia.org/wiki/Domain-driven_design";>DDD</a>).</p>
+
+<h2 id="background">Background</h2>
+
+<p>SecKill idea comments from the Internet popular promotions, using coupons 
to obtain some discounts; because the number of coupons is limited, so we must 
provide a platform for everyone who wants to get it fair competition.</p>
+
+<p>As a demo project, so we don’t want make the SecKill too complicated; we 
just use the most primitive strategy - first come first get. It is quite simple 
if you want to implements other strategies by yourself.</p>
+
+<h2 id="first-design">First Design</h2>
+<p>Now let’s analyze requirement in customer bounded context:</p>
+<ol>
+  <li>Customer try to grab a coupon, SecKill return the coupon according to 
the coupon in inventory;</li>
+  <li>Customer cannot get the coupon anymore if he already send the request to 
the system.</li>
+  <li>Customer can query how many coupons he owned.</li>
+</ol>
+
+<p>Let’s go! what? you say this description is to simple? because they are 
no registration system, and promotion is how come, how to start? which coupon 
the customer request for? Is the discount all same? etc.</p>
+
+<p>Actually, we are accustomed to thinking a lot at the beginning, so some 
larger system, the design stage may be a few months, but this time you can’t 
consider too much, because we believe:</p>
+
+<ol>
+  <li>Over-design can’t guarantee fully meeting the demand after 
construction completed, the only constant is the demand is always changing, so 
don’t over-design;</li>
+  <li>The principle of the microservice architecture is that service provides 
single function, so each components(microservices) only need to provide small 
service, without having to design all the services in system one-time;</li>
+  <li>Should be solve the problem of the core domain as soon as possible.</li>
+</ol>
+
+<p>Then, we can follow the many principles of domain-driven design (<a 
href="https://en.wikipedia.org/wiki/Domain-driven_design";>DDD</a>). The core 
task of the design process is identify entities, value objects, services and 
other elements, and further search aggregation; because our requirements are 
very simple, so it’s easy find them out:</p>
+<ul>
+  <li>Entities:Promotion</li>
+  <li>Value-Object:Coupon,PromotionEvent</li>
+  <li>Domain Service:SecKill</li>
+</ul>
+
+<p>Now we can find the aggregation between them, separated two microservice, 
now we direct use MySQL database for shared data (although microservice 
recommend use independent storage for each, we can revisit it in the next 
iteration)</p>
+<ol>
+  <li>Command : for SecKill domain service</li>
+  <li>Query : for query Coupon Value-Object</li>
+</ol>

+<p>The source code at <a 
href="https://github.com/ServiceComb/seckill";>Github</a>, Welcome to Watch and 
Star : )</p>
+<h3 id="implement-of-command-micro-service">Implement of Command 
micro-service</h3>
+<p>We create two class “SecKillCommandService” and 
“SecKillPersistentRunner” to accept seckill request and persist seckill 
result, considering persistence is slow, we use BlockQueue temporary cache 
requests. another class “SecKillCommandRestController” act as Endpoint; 
ServiceComb support a variety of programming models and communication model, 
also well support Spring Boot, and easy deploy to Huawei cloud.</p>

alt="Fig-2 Command micro-service components" class="align-center" /></p>
+
+<h3 id="implement-of-query-microservice">Implement of Query microService</h3>
+<p>Query logic is relatively simple, because PromotionEvent is Value-Object, 
we use PromotionEvent records to get Coupon Value-Object, you can read the 
source code and understand this process.</p>
+
+<h2 id="support-domain-implement">Support Domain Implement</h2>
+<p>As promotion is entity and seckill need it as preconditions, we need build 
and manage it in another domain, because it’s not so urgent at current stage, 
we can use Spring injection autowire fix objects.</p>

+        <p><a href="/docs/seckill-development-journey-part/">Previous 
article</a> We only built a core function seckill demo, this article we will 
gradually improve more features in order to let it had complete function.</p>
+
+<h2 id="problems">Problems</h2>
+<p>Review what we has been done, we can find that:</p>
+<ol>
+  <li>Service for Promotion entity is not provided (inject by Spring);</li>
+  <li>Lack some base check and features, include:
+    <ul>
+      <li>One customer can only grab one coupon per promotion</li>
+      <li>Support multi promotion activing (discount of each promotion is 
different)</li>
+    </ul>
+  </li>
+  <li>If Command micro-service down, it will recovery all uncompleted 
promotions immediately before start-up again.</li>
+</ol>
+
+<p>Maybe you would say that customer management and customer login function 
are not listed? Indeed, the customer is indispensable in our scenario, in order 
to simply design, we don’t include login and token authentication etc., if 
you are interesting about this, you can see ServiceComb’s <a 
href="https://github.com/ServiceComb/ServiceComb-Company-WorkShop";>Company</a> 
demo application to get more information.</p>
+
+<h2 id="improvement-design">Improvement Design</h2>
+<p>For entity, domain-driven design (<a 
href="https://en.wikipedia.org/wiki/Domain-driven_design";>DDD</a>) recommended 
to use a separate interface, so we design a new Admin micro-service to provide 
service:</p>
+
+<p><img src="/assets/images/seckill-develop-course-part-II-arth-en.png" 
alt="Fig-1 Architecture after Admin micro-service added" class="align-center" 
/></p>
+
+<h2 id="improvement-implement">Improvement Implement</h2>
+<h3 id="implement-of-admin-micro-service">Implement of Admin micro-service</h3>
+<p>Admin micro-service only provide services for promotion entity, we can map 
this function to REST method:</p>
+<ul>
+  <li>New promotion map to Post;</li>
+  <li>Modify promotion map to Put;    </li>
+  <li>Query promotion map to Get;    </li>
+  <li>
+    <p>Delete promotion map to Delete.  </p>
+
+    <p>To match current requirement we only need implement Post and Get, In 
addition, already started promotion should not be able to modify, so we 
increased the corresponding check.</p>
+  </li>
+</ul>
+
+<h3 id="new-check-and-features-implement">New check and features Implement</h3>
+<p>Add a HashSet per promotion to check whether customer had grab coupon; <br 
/>
+  Add “SecKillPromotionBootstrap” class as promotion bootstrap manager for 
support multi active, “SecKillCommandService” and 
“SecKillPersistentRunner” now managed(create) by it。</p>
+
+<h3 id="command-micro-service-auto-recovery-implement">Command micro-service 
auto recovery Implement</h3>
+<p>Add “SecKillRecoveryService” class to check state of promotion, 
uncomplement promotions whether unstart or activing all need check by it to 
init start-up information including left coupons, grabbed customers list, 
etc.</p>
+
+<h2 id="function-verification">Function Verification</h2>
+<p>Finally, we use PostMan to check completed functions, Please ensure request 
body fill with JSON format, and set Content-Type to application/json:</p>
