Weidian is a mobile app that helps sellers open shops. It has gone through several architectural stages: monolithic, multi-module, and microservices using Dubbo. Challenges in the microservices stage included module splitting, automated deployment, call tracing, monitoring and alarms, flow control, and high availability during data center migration. Solutions involved domain-driven design, DevOps practices like Docker and configuration management, and modifying Dubbo components. Future plans include contributing back to the Dubbo community, supporting multiple languages through agents, and exploring reactive and functional programming approaches.

As a leading IT service provider in the consumer finance field, Shanghai Rongzhijia Financial Information Service Co., Ltd. built China's first Internet loan search platform. It went from zero to over 30 million users, who have taken out nearly 15 billion RMB in loans through the platform within only two years.
This slides introduces how they evolve their IT system from monolithic application to a Dubbo based micro-service architecture.
Mail is received as a commodity from the cloud, also Collaboration. However, in many client meetings we often hear the question, where are we heading with the hundreds of Notes applications? Which strategy is most effective and cost efficient at the same time? Is cloud a practical answer? With sound and proven methodology Notes applications can be transformed into valuable web applications in the cloud. It turns out that today the time has come for cloud platforms. A side view of large customer projects, already transforming their Notes applications to the cloud - for example to IBM SoftLayer - is helpful. This Track helps you understand that strategies that are implemented and lets you understand the costs and risks involved.

Early Draft: Service Mesh allows developers to focus on business logic while the crosscutting network data layer code is handled by the Service Mesh. This is a boon because this code can be tricky to implement and hard to test all of the edge cases. Service Mesh takes this a few steps further than AOP or Servlet Filters or custom language-specific frameworks because it works regardless of the underlying programming language being used which is great for polyglot development shops. Thus standardizing how these layers work, while allowing teams to pick the best tools or languages for the job at hand. Kubernetes and Istio Service Mesh automate best practices for DevSecOps needs like: failover, scale-out, scalability, health checks, circuit breakers, rate limiters, metrics, observability, avoiding cascading failure, disaster recovery, and traffic routing; supporting CI/CD and microservices architecture.
Istio’s ability to automate and maintaining zero trust networks is its most important feature. In the age of high-profile data breaches, security is paramount. Companies want to avoid major brand issues that impact the bottom line and shrink market capitalization in an instant. Istio allows a standard way to do mTLS and auto certificate rotation which helps prevent a breach and limits the blast radius if a breach occurs. Istio also takes the concern of mTLS from microservices deployments and makes it easy to use taking the burden off of application developers.

Buzz word! More buzz words! And another buzz word!! Now that that's out of the way, if you're thinking of heading down the microservices path, then how do you do it? How do you build the services? What do you need to think about if you're starting from scratch? What if you're converting a legacy app? How do we deal with versioning? Do we have to use a NoSQL solution, just because Netflix does? Do we need to use docker/containers? What about the code? Show me the code! Well, that's what this session is all about. Designing and building microservices in .NET and then handling a bunch of other concerns that a microservices approach will force you to think about. Sounds interesting, doesn't it? You betcha.

IURII IVON, EPAM Solution Architect, Microsoft Competency Center Expert.
The term ‘microservices’ has become so popular that many people see it as a silver bullet for all architectural problems, or at least as a trend that should be followed. If your project is a monolith today, does it make sense to move towards microservices? This presentation overviews painful issues to be considered when migrating from a monolith to microservice architecture, ways to solve them, and ideas on the feasibility of such migration.
The introduction covers the following
1. What are Microservices and why should be use this paradigm?
2. 12 factor apps and how Microservices make it easier to create them
3. Characteristics of Microservices

Cloud-native Data: Every Microservice Needs a Cachecornelia davis
Presented at the Pivotal Toronto Users Group, March 2017
Cloud-native applications form the foundation for modern, cloud-scale digital solutions, and the patterns and practices for cloud-native at the app tier are becoming widely understood – statelessness, service discovery, circuit breakers and more. But little has changed in the data tier. Our modern apps are often connected to monolithic shared databases that have monolithic practices wrapped around them. As a result, the autonomy promised by moving to a microservices application architecture is compromised.
With lessons from the application tier to guide us, the industry is now figuring out what the cloud-native architectural patterns are at the data tier. Join us to explore some of these with Cornelia Davis, a five year Cloud Foundry veteran who is now focused on cloud-native data. As it happens, every microservice needs a cache and this evening will drill deep on that topic. She’ll cover a variety of caching patterns and use cases, and demonstrate how their use helps preserve the autonomy that is driving agile software delivery practices today.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

8. Servitization-Module split
Complex business relations
How to split the module?
• Consider the business first VS
Consider the data table first?
• Should the number of lines of code
be used as the basis for
subcontracting?
• How to balance the pursuit of design,
engineering, and operation?
9. Servitization-Module split
u Microservice:
• System consisting of distributed services
• Organize organizations by business rather
than technology
• Automated operation and maintenance
• Rapid evolution of service iteration
u DDD Domain-driven Design
• Solve core issues in the domain by building domain models
• Implementation of code driven by domain models
• Technical architecture design or data storage, etc. are on the
periphery of the domain model
• DDD vs SSI（spring+hibernate）: congestion model / blood loss
model
Split principle:
• DDD Business-driven
• Balance of design,
engineering, operations,
etc.
• Progressive evolution

DUBBO
How to replace the dubbo
version of the private
maintenance with the latest
dubbo version?
• Serialization compatibility (in the rolling upgrade,
the business is guaranteed to be ordered)
• After graduating from the apache community, the
package will be changed from com.alibaba.dubbo to
org.apache.dubbo and will provide an extension.
Private dubbo version,
how to integrate with the
official version of dubbo?
• Please submit your private extension to
the dubbo communitydubbo
• Dubbo official will make the best
practices in the following areas:
rpc tracking, current-limiting fuse,
multi-language support, etc.
19. About the future-Multi-language support
l Method：
Use a effective language to develop a agent, other than
JAVA language can interact through the agent process
and registry. (Service mesh sidecar mode)
Benefit ：
No need to implement a dubbo client in every language
(in multi-language communication, thrift, gRPC and other
serialization frameworks based on tcp protocol will
perform better than http1+json) serialization
Problem：
A node has been added: when the agent process is
abnormal or hangs, the business process of the agent
service has to remove the traffic.

1, Service as a function;
2, function is in line with the functional
programming paradigm: transparent
reference, no side effects, can be combined,
