A proper Microservice is designed for fast failure.
Like other architectural style, microservices bring costs and benefits. Some development teams have found microservices architectural style to be a superior approach to a monolithic architecture. Other teams have found them to be a productivity-sapping burden.
This material start with the basic what and why microservice, follow with the Felix example and the the successful strategies to develop microservice application.

Architecture: When, how, and if to adopt microservices - Microservices are not for everyone! If you're a small shop, a monolith provides a great amount of value and reduces the complexities involved. However as your company grows, this monolith becomes more difficult to maintain. We’ll look at how microservices allow you to easily deploy and debug atomic pieces of infrastructure which allows for increased velocity in reliable, tested, and consistent deploys. We’ll look into key metrics you can use to identify the right time to begin the transition from monolith to microservices.

Microservices architectures are changing the way that organizations build their applications and infrastructure. Companies can now achieve new levels of scale and efficiency by disaggregating their large, monolithic applications into small, independent “micro services”, each of which perform different functions. In this session, we’ll introduce the concept of microservices, help you evaluate whether your organization is ready for microservices, and discuss methods for implementing these architectures. We’ll also cover topics such as using API gateways, enabling self-service infrastructure provisioning, and ways to manage your microservices.

Tokyo Azure Meetup #5 - Microservices and Azure Service FabricTokyo Azure Meetup
Azure Service Fabric is now Generally Available!
In this meetup we will start from the beginning and define what is microservice.
Next we will have a deep dive in Azure Service Fabric. Azure Service Fabric is one of the most interesting Azure service. Used internally in Microsoft for 5 years and backing up one of the most demanding Azure services today such as Azure SQL, Document DB, Cortana and Skype for Business.
We will be talking about the two models that are supported by Azure Service Fabric:
- Reliable Services (We will explore the reasons for having both stateful and stateless offerings in this model)
- Reliable Actors
Then we will talk how you can create Azure Service Fabric cluster on premise or in another cloud.
We will demo deployments in Azure for the various models.
Azure Service Fabric is the most advanced and complete offering for developing and hosting microservices in Azure. It builds on years experience Microsoft acquired running one of the most demanding services such as Azure SQL. Moreover, Azure Service Fabric solves very difficult distributed computing problems such as data synchronization, zero downtime deployment, update and rollback operations at large scale.
Join us to learn more about Azure Service Fabric and start using it immediately after the meetup!

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days.

3. What is a Microservice?
• “The microservice architectural style is an approach to develop single application as a suite of small services,
each running in its own process & communication with light weight mechanism.” . James Lewis & Martin
Fowler.
• “Microservices are SMALL & AUTONOMUS services that work together”. Book - Building Microservices, Sam
Neuman.
• There is no specific technology used to build MS.
• Some Principles and architectural patterns are used to build MS.
3 16 May 2019
4. Microservice overview
Micro
• Big/small, who decide ?
• Is it the number of lines in code ?
• Is it the number of developers in
team?
• There is no universal measure . One
microservice should do ONE THING
& do it well.
• It is micro because of the scope of
functionality not line of code.
• Subdomains should be identified to
know the scope of functionality.
• Bounded context
• Should be built around business
capability
5. Microservice overview
Service
• It is an independently deployed component for bounded context.
• Interoperability.
• Uses message based communication.
• Independent from technologies.
• Simply it is SOA
6. Monolithic application
Simply a monolithic application consists of
• Model
• Single database
• User interface
• APIs can be exposed for third parties
• You can have more than one instance running behind load balancer
8. Monolithic application
Pros
• Simple to build
• Simple to test
• Simple to deploy
• Simple to scale
• Multiple instances
• Simple to develop
• Limited to one language.
Cons
• The bigger the app, the bigger the team.
• New team members productivity is low.
• Code harder to understand & modify.
• Not updated with new technologies.
• Startup of app will take long time.
• Scale for bad reasons
• Need more CPU for calculating invoices, you will
scale the whole app.
9. Monolithic application
• Taking monolithic app and dividing it to smaller services will lead to:
• Concentrating on something smaller
• Software life cycle is still the same, but moves faster.
• Smaller teams
• Small services will live side by side.
10. Moving to Microservice
• Microservice should be “Domain Driven Design”.
• Taking the monolith application and moving to domain driven design
• Domain:
• E-commerce
• Sub-domains:
• User: Auth, profile, address,…
• Order: invoices, discount,…
• Product: Prodcuts, suppliers,…
• Dependencies:
• Sub domians should be totally independent. If you find any dependencies duplicating entities is
required.
12. Moving to Microservice
• Organization
• Teams will be divided by subdomain not domain
• Right sized team for each subdomain
• Each team will be solely responsible for their final product
• Each team should be independent, but the communication between them should be
handled by management
• Each team should have their own repo.
13. Moving to Microservice
• Data store
• Each MS should have its own database
• Example:
• Product: relational database
• Order: NoSQL
• User: LDAP
• Problem ?!
• If user changes his address it should be replicated in the entity found in order sub-domain.
• In MS world there is no distributed transaction [ in same transaction you update more than 1 table in
different databases] due to performance issures
• Therefore, data is not immediately consistent.
14. Moving to Microservice
• Data store
• Solution for data sync is using change data capture or event sourcing pattern.
• Both are ways of modeling data, especially at scale, using a combination of a mutable database.
• Service publishes event when data changes and other services will consume the event and
update data.
• Kafka can be used for keeping data in sync
• UI
• Composition pattern can be used to be consistent
• Client side
• Server side
15. Moving to Microservice
• Services
• Communication
• Remote Procedure Invocation/call (RPC):
User Order Product
• Request / reply principle (purchase request product price)
• Can be sync/async
• REST or SOAP can be used
16. Moving to Microservice
• Services
• Communication
• Messaging:
• Message or events
• On broker or channel
• MS can publish an event & the MS who is in need can subscribe to broker & receive the message at a later
time
• Kafka can be used also.

17. Moving to Microservice
• Services
• Communication
• Using any of the two methods you need protocol format exchange
• Text (JSON, XML,…) readable and easy to implement
• Binary (gRPC) more compact
• MSs need contracts to know the APIs of other MSs.
• Example: WSDLs & Swagger files.
18. Moving to Microservice
• Distributed services
• MSs are deployed where there network locations are changed dynamically.
QUESTION?
How can MSs communicate with each other when there locations are changed
dynamically ?
ANSWER
Service registery
19. Moving to Microservice
• Distributed services
• Service registry
• It is a phonebook of services
• MSs should register them selves on startup and at shutdown
• You can lookup by their logical names
• Product: 127.0.0.1:8080
• Eureca can be used for this
20. Moving to Microservice
• Distributed services
• Best way for FE to call MS is putting an API gateway

API Gateway
21. Moving to Microservice
• Distributed services
• Best way for FE to call MS is putting an API gateway
• Unified interface
• Can control the cross cutting functionalities (Authentication, Authorization, register, …)
• API translation
22. Moving to Microservice
• Security
• Use identity and access mangement for authentication and authorization.
• Once signed in Access-token can be used to move from one MS to another
• Scalability
• You can scale one MS or more.
• Scaling can be:
• Vertical:
• adding more power to existing machine (more CPU/RAM …)
• Horizontal:
• replicate more machines. i.e. several instances
• Client load balancing will choose from registry. (using round robin for example)
Product1: x.y.z:80
Product2: a.b.c:81
23. Moving to Microservice
• Availability
• Minutes is up and operational
• We have in this architecture some single point of failures
• Broker
• API Gateway
• Registry
• ALL POF should be scaled horizontally (multiple instances) & clustered to be in sync
24. Moving to Microservice
• Monitoring
• Should be centralized
• Use log aggregation (Log stash can be used)
• Should be visual in dashboard (Splunk/ Kibana can be used)
• Health check
• Service running. Cant handle requests. Should show database status, available space,…
• Record exceptions in tracker system cyntralized
• Gather statistics (DropWizard can be used)
• Limit traffic to defend DOS attachks
• A coorelation id (transaction_id) for the journey of the request (dapper can be used)
25. Moving to Microservice
• Deployment
• Can be on physical or virtual servers (still physical but can control CPU/RAM)
• MS should be packaged with its dependencies in container image & deployed as a
container
• Images can be easily moved from one environment to another. ( Docker to be used)
• Kubernetes is used to orchestrate the contianers
• Jenkins is used for continuous delivery
• There should be an external configuration for diff environments
• Putting debug mode in dev environment only
• Activating new functionality through configuration
26. Challenges
• Business concerns
• Integration between teams is difficult
• Many trainings need to be done as different dev. Stacks
• There is no standard in MS.
• Solution will rely on some standards (HTTP,SQL,..) but not standard stack.
• There is no single framework, but there is an integration of different technologies
• No single support
• Cost
• Small team
• Cheap start, cheap deployments on cloud
• Time
• Faster to market.
27. Challenges
• Technical concerns
• Design
• How to partition the system to services (invoices could’ve been services)
• How small !?
• Technical diversity
• Choose programming language
• Right database
• Distribution
• Communication over network
• How to deal with network failures (circuit breaker)
• Data store
• Database per subdomain
• Keep data in sync
• Security
• Access token renewal
28. Challenges
• Technical concerns
• Testing
• Less code will be tested
• Test in isolation
• Integration testing is hard
• Maintenance
• Less code to maintain
• Less code to understand
• Extensibility
• New feature, new MS
29. When to use MS ?
Time to market Extensibility
