Graffiti Smart Cloud Second Generation
As the volume of business increases, database pressures increase. In the second generation architecture of the graffiti intelligent cloud, the split layering is carried out. Compared with the first generation architecture, the gateway layer has almost no changes, and the risk is controllable;
The middle layer is modularly split, and the service governance is based on Ali's Dubbo . At the same time, some corresponding improvements have been made to make it more suitable for the gateway layer, and the configuration center dynamic configuration takes effect.
At the same time, the Dubbo monitor is used to monitor the service, and at the same time, the call dependency of the service governance is developed.
At present, there are more than a dozen graffiti intelligent internal services. In terms of database, the database middleware is developed by graffiti technology to realize routing, sub-database sub-listing, master-slave backup and other operations. By optimizing the architecture, the second-generation architecture has better support for the business:
In terms of data, it can currently process 30T data uploads per day ; it can run billions of user core data; support real-time log search and analysis of alarms, and support offline and real-time data processing.
In terms of modularization, the business services are modularly split, so that they can be independently deployed and deployed; at the same time, the service management tool can analyze the service call situation and expand capacity as needed; through performance and availability monitoring, timely discover technical bottlenecks and support service hot release.
On the gateway side, the internal and external data is isolated by the gateway; the gateway service is used to assemble the service scenario to make the module granularity more detailed; in addition, the gateway provides multiple security mechanisms to support multiple service scenarios; the gateway can be parallelized and has no performance. The bottleneck; the gateway acts as a unified data entry and exit, which facilitates log analysis and tracking.
In terms of middleware, through independent development of data components to support sub-database sub-tables, master-slave read and write operations; at the same time, Mq and other intermediate services package, easy to structure selection; in addition, the use of Alibaba Cloud as much as possible to reduce maintenance costs. At the same time, through the configuration center, the real-time update requirements of the gateway interface are met.
Graffiti Smart Cloud Use Experience Skills
Graffiti Intelligence is based on Alibaba Cloud's deep customization optimization design. In RAM permissions, different clients use different Keys , hide Super Key , use RAM custom permissions to refine to each user, and reduce security risks by splitting the business.
In the cloud monitoring skills, through regular monitoring of ECS , RDS , OCS, etc., how to make an alarm in time can be modified. Through the survival of the customized monitoring service, due to the limited amount of information for custom monitoring, the self-monitoring is developed later, and the link address of the log analysis is added to the monitoring information. If an alarm occurs, the link address can be used accurately. Find the problem. Internal service management through SLB , the first SLB intranet is free to use, very flexible. When the front-end Nodejs server calls the back-end API , the internal network is built through the SLB to avoid the unavailability caused by the replacement of the internal network server and the offline. In addition, the ZooKeeper cluster is managed through SLB , eliminating the need to change the code and avoiding risks. OSS, through the OSS picture service reduces costs, but also through the interior of the OSS management operation and maintenance of small tools, through the Python Client OSS operation and maintenance of the autonomy of some servers.
Insert Q&A :
(Alibaba Cloud) Q: As a technician, can you share your entrepreneurial experience in the past few years?
( Ke) Answer: Entrepreneurship has a lot of feelings during this period of time. When you are at the company, you are more focused on doing your own business. You don’t know much about other knowledge. When starting a business, you should not only focus on improving your own technology, but also focus on the development of the team, connecting the entire link and growing up.
(Alibaba Cloud) Q: What development process should a perfect architecture undergo?
(Ke) A: I personally think that there is no perfect architecture, and the architecture that is most suitable for business is the best.
At present, graffiti intelligence based on its own cloud architecture technology advantages of design, tool development, operation and maintenance experience, regardless of security or monitoring efficiency are industry-leading and very suitable for our customers ...
" Graffiti Cloud " is based on the authority control of the ECS security group
The graffiti cloud is based on the permissions of the Alibaba Cloud ECS security group. Before the ECS security group is not listed, the firewall method is deployed on each machine. The firewall rules are deployed on different servers. When the firewall needs to be modified, it needs to be processed on the machine, which is very cumbersome.
Through the ECS security group, the corresponding firewall rules are sorted out. For example, all the log analysis servers can be added to the log analysis service security group, which is very flexible. In addition, intranet communication can be performed in the security group, and the security group and the customized security group that Alibaba Cloud comes with are also opened.
Graffiti cloud based on ECS API for host management and high availability monitoring
Graffiti on Intelligence ECS API developed a set of tools: This tool can get the list of machines and information (RAM permissions), and then to each machine through the host Tag marked Tag management, different developers can only contact with the corresponding machine . By Tag labeled, so that the host may demand management, batch operation and maintenance, but also can be done according to the corresponding availability monitoring Tag type.
Through the real-time analysis of all data, the tag of Tag is used to clarify the type of service, and the analysis result is called based on the service type. For example, it can analyze the error amount of the gateway in a certain period of time, and the response time of the network. If the error amount or response time exceeds a certain threshold, an automatic alarm can be performed without human intervention, and the developer can quickly locate the problem by using the URL address provided by the alarm .
On the basis of security far more than before, the efficiency in host management, batch operation and maintenance, availability monitoring, and positioning problems has been greatly improved ...
At the same time, it also ensures that the graffiti intelligent cloud has a greater advantage in terms of network access time, stability, use cost and technical support than the peers.
