Lean Microservices with OSGi - Christian Schneidermfrancis
OSGi Community Event 2016 Presentation by Christian Schneider (Talend)
Microservices and their frameworks like spring boot allow to start fast but can easily produce ugly monoliths or tangled webs of fine grained dependencies. OSGi on the other hand provides great modularity but is regarded as more complex than spring boot and alike. This Talk shows how to create lean and modular microservices using OSGi, maven, bndtools and Apache Karaf. The build result is a runnable jar or docker image and nicely fits microservice deployments. See how OSGi allows the flexibility to deploy each microservice on its own and let them communicate over (REST) remote calls or deploy them together and talk using OSGi services locally using the same business code bundles.

Navigating the service mesh landscape with Istio, Consul Connect, and LinkerdChristian Posta
Service mesh has hit the cloud native computing community like a storm, and we’re starting to see gradual adoption across the enterprise. There are a handful of open source service mesh implementations to choose from, including Istio, Consul Connect, and Linkerd.
Christian Posta details why and when you may want to use a service mesh versus when you may want to just stick with a library, Netflix OSS, or application approach. He digs into three popular open source service mesh implementations and explores their goals, strengths, and weaknesses. You’ll come away with a good foundation from which to explore service mesh technology and ask the right questions to get to the right answer for them.

Connecting All Abstractions with IstioVMware Tanzu
SpringOne Platform 2017
Ramiro Salas, Pivotal
The concept of a service mesh represents a paradigm shift on application connectivity for distributed systems, with wide implications for analytics, policy and extensibility. In this talk, we will explain what a service mesh is, the power it brings to microservices, and its impact on Cloud Foundry and K8s, both separately and together. We will also discuss the implications for the traditional network infrastructure, and the shifting of responsibilities from L3/4 to L7, and our current thinking of using Istio to integrate all abstractions.
Microservices Integration Patterns with KafkaKasun Indrasiri
Microservice composition or integration is probably the hardest thing in microservices architecture. Unlike conventional centralized ESB based integration, we need to leverage the smart-endpoints and dumb pipes terminology when it comes to integrating microservices.
There two main microservices integration patterns; service orchestration (active integrations) and service choreography (reactive integration). In this talk, we will explore on, Microservice Orchestration, Microservice Choreography, Event Sourcing, CQRS and how Kafka can be leveraged to implement microservices composition
Nodeconf Barcelona 2015 presentation exploring several ways of building microservices in an asynchronous way. Presented the concept of a broker as an alternative to a multiple point-to-point architecture.
Microservice architecture is a new way of developing an application as a suite of independently deployable and manageable small services talking to each other using web services(REST) or a message broker(AMQP). While there is no precise definition and others consider microservices to be simply an ideal, refined form of SOA(Service-oriented architecture ), each microservice should be relatively small so that it's easier for a developer to understand, use suitable framework and IDE, deploy, scale, easily isolate fault.

In questa sessione di formazione, i sistemi informatici (a titolo d’esempio) da sottoporre al processo d’integrazione sono due e appartengono a due diverse tipologie:
Content Management System – CMS
Customer Relationship Management – CRM
Il CMS che prenderemo come riferimento è rappresentato dalla soluzione software Open Source (scritto in PHP) Joomla, invece il CRM che prenderemo come riferimento è rappresentato dalla soluzione software Open Source (scritto in PHP) SugarCRM.
Intro to OSGi – the Microservices kernel - P Kriens & T Wardmfrancis
If you are new to OSGi, or have heard about it or experienced (good or bad) a little of OSGi then this is the talk for you.
Peter Kriens, the OSGi Alliance Evangelist and Tim Ward, co-author of Enterprise OSGi in Action will provide a high level technical introduction to OSGi, covering the core concepts that make up this standard.
OSGi has been around since 1998 and was formerly JSR8. Today its one of the only Java standards that exist outside of the JCP and this talk will explore the original objectives of OSGi and how they have remained true while being extended to apply across many vertical markets including enterprise, embedded / IoT, etc.
Microservices and OSGi. From the outset OSGi promoted a ‘services-first’ approach, initially within the JVM, and in the last few years, across JVM’s with the Distributed OSGi specifications. The Microservices approach has been gaining industry traction over the last 12 months and Peter and Tim will explain how OSGi provides you with a standards-based solution to Microservices, how simple it is to take advantage of, and the benefits that you can achieve by adopting OSGi to realize it.
They will also highlight some of the common misconceptions and challenges that people have when starting out with OSGi, just so you have a full and frank understanding of the many benefits and some of the hurdles you may encounter as you start down the OSGi path. As they say there is no such thing as a free lunch, however it tastes mighty fine once you get there!

QCon Sao Paulo Keynote - Microservices, an Unexpected JourneySam Newman
Microservices are the hot new thing, but where did they come from, and where are they going?
This keynote will take you through the many origins of microservices. In it I’ll share with you some of the surprising influences and prior art that have shaped what they have become.
By understanding where microservices architectures have their roots, we can learn from the past and avoid making the same mistakes – and we can also start to see where microservices will be going next.
This talk was delivered as the keynote at QCon Sao Paulo in 2015.
Introduzione ai sistemi di Content Management System (CMS)Antonio Musarra
Un Content Management System, in acronimo CMS, letteralmente "sistema di gestione dei contenuti", è uno strumento software installato su un server web studiato per facilitare la gestione dei contenuti di siti web, svincolando l'amministratore da conoscenze tecniche di programmazione.
Current tech marketing aims at making you fall in love with microservices. But do you know their benefits and their requirements? What about their feasibility?
AWS re:Invent 2016: Moving Mission Critical Apps from One Region to Multi-Reg...Amazon Web Services
In gaming, low latencies and connectivity are bare minimum expectations users have while playing online on PlayStation Network. Alex and Dustin share key architectural patterns to provide low latency, multi-region services to global users. They discuss the testing methodologies and how to programmatically map out a large dependency multi-region deployment with data-driven techniques. The patterns shared show how to adapt to changing bottlenecks and sudden, several million request spikes. You’ll walk away with several key architectural patterns that can service users at global scale while being mindful of costs.
This is a small introduction to microservices. you can find the differences between microservices and monolithic applications. You will find the pros and cons of microservices. you will also find the challenges (Business/ technical) that you may face while implementing 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.

Monoliths, Myths, and Microservices - CfgMgmtCampMichael Ducy
Moving from a monolithic based architecture to a more microservices architecture can be fraught with challenges. We'll talk about some of these challenges and some common myths associated with trying to strangle the Monolith. We'll also talk about config management and automation's critical role in helping you move to a microservices architecture, and how our monolithic approach to automation changes in the new world.
These are my summarized notes from all the microservices session I attended at QCon 2015. These sessions had tons of learning around how to scale microservices and avoid common pitfalls

Stephen Pember shares his experience migrating from a monolith to microservices across several companies, highlighting the mistakes made along the way and offering advice.
Are you jumping on the microservices bandwagon? When and when not to adopt micro services architecture? If you must, what are the considerations? This slidedeck will help answer a few of those questions...
Creating an Elastic Platform Using Kafka and Microservices in OpenShift confluent
(Pradeep Chintam, American Express Global Business Travel) Kafka Summit SF 2018
When a new project, Global Trip Record was launched at American Express GBT and we were looking for a robust, scalable and fault-tolerant middleware to handle all the orchestration and connectivity needs of the project.
The existing solution was monolithic, and we wanted to convert that to a microservices framework, but the biggest challenge was managing the increasing number of external applications that are connected to the platform. Any slow external application or partner system connected to the platform was slowing down the entire platform. There is always a need for partner systems to go offline or a need to resend the entire day’s data, especially with a system like our data lake where the data volumes are huge.
After evaluating multiple solutions, we settled on Apache Kafka, and started with a simple implementation of around 100,000 messages to just decouple one partner system and the core platform.
Today, we are running our microservices (Docker) running in OpenShift (Kubernetes) processing Kafka Streams, running real-time anomaly detection using Kafka Streams, powering our data lake through Kafka, feeding our distributed caching layer (Apache Ignite) and connecting all internal and external systems using Kafka. With a total of more than 10 million messages per day, i.e., 1.5TB of data with just a small three-node cluster, we are one happy platform for over a year now. With the kind of stability, flexibility and success in our project, a lot of other teams started and will soon be in production with Kafka Steams. The powerful combination of Kafka and OpenShift has proven to be an easily scalable model with great elasticity to the entire platform.
Surviving in a microservices environmentSteve Pember
Many presentations on Microservices offer a high level view; rarely does one hear what it’s like to work in such an environment. Individual services are somewhat trivial to develop, but now you suddenly have countless others to track. You’ll become obsessed over how they communicate. You’ll have to start referring to the whole thing as “the Platform”. You will have to take on some DevOps work and start learning about deployment pipelines, metrics, and logging.
Don’t panic. In this presentation we’ll discuss what we learned over the past three years. We’ll examine what a development lifecycle might look like for adding a new service, developing a feature, or fixing bugs. We’ll dive a bit into DevOps and see how one will become dependent on various metric and centralized logging tools, like Kubernetes and the ELK stack. Finally we’ll talk about team communication and organization... and how they are likely the most important tool for surviving a Microservices development team.
Liberty: The Right Fit for Micro Profile?Dev_Events
Kevin Sutter, Senior Technical Staff Member, IBM @kwsutter
Alasdair Nottingham, Websphere Runtime Architect, IBM @notatibm
The move to microservices is well under way, but has enterprise Java adapted to these new realities? Although some argue that enterprise Java is irrelevant, many of its tried-and-proven APIs are highly applicable to microservice architectures. And the need for new APIs to address challenges inherent in highly distributed microservices is clear. The recent announcement of the Micro Profile initiative (microprofile.io) to define new application server portable APIs means that these needs will be addressed. This session explores what Micro Profile is, how it can help with microservices, and how WebSphere Liberty’s à la carte approach to Java EE can help enable microservices by using the new Micro Profile and ldemo Liberty plus the microProfile-1.0 feature.

Venez le découvrir lors de cette session ignite
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

!
– Hard to focus teams and efforts
#LRNAS2014
12. The scale cube
X-Axis scaling
!
• Multiple copies running behind a load balancer
!
• Ideally, each copy handles 1/N of the load
!
• Great way to improve capacity and availability
!
• Common approach to scaling

Z-Axis scaling
!
• Each server runs and identical copy of the code
!
– Similar to X-axis scaling
!
• But each server is in charge of a subset of the data
!
• We need smarter routing
!
• We can apply the similar concepts to applications
!
• Sharding, SLA, …

Gateway API
!
• API tailored client
!
• Encapsulation
!
• Composition
!
• Different evolution
#LRNAS2014
29. Interprocess communications
Synchronous RPC
!
• REST or SOAP
!
• Both are “simple?” and familiar
!
• Firewall friendly
!
• Discovery service (Zookeeper, Etcd, …)
!
• IMHO, there is better options than HTTP
#LRNAS2014
30. Interprocess communications
Asynchronous messaging
!
• “AMQP like” message broker
!
• Decouple producers from consumers
!
• New element to deploy and manage (the message broker)
!
• Actor model?
#LRNAS2014
32. Data management
Decentralized data management
!
• Each service, potentially, could have its own database
!
• Even different types of databases (SQL, NoSQL, …)
!
• Distributed transactions come into place :(
• 2PC, 3PC, …
!
• Event-driven asynchronous updates
!
• Different consistency model
#LRNAS2014
36. OSGi μServices
Features
!
• Run within the same JVM
!
• Highly dynamic
!
• Implemented within the Service registry
!
• Runtime lifecycle management
#LRNAS2014
39. Focused components
OSGi modules and services
!
• Modules allow us to hide implementations and decouple
!
• Use service layer to communicate each other
!
• They can be deployed independently
!
– For now we are talking about single JVM
!
• Modules/services can disappear at any point in time
– Highly dynamic
!
– Closely related to distribution (more details later on)
#LRNAS2014
41. Fault isolation
Not real fault isolation
!
• We get independent deployments through bundles
!
• Living within the same JVM. No real fault isolation
!
• A service could consume the whole CPU/memory or
saturates the network
!
• Some research work on multi tenant JVM by IBM
#LRNAS2014
43. Tech commitment
Partial breakage with long tech commitments
!
• We already have isolated and highly focused pieces
!
• Communication is done through services
!
• Some nice JVM based alternatives: Scala, Clojure, Groovy,
…
!
• Cannot use a completely different tech: Erlang, Go, …
#LRNAS2014
45. Missing pieces
We are still missing …
!
• Independent scaling of every service
!
• Real isolation
!
• Solutions to the previous problems
!
• Process (JVM)
!
• Linux Containers (Solaris Zones, …)
!
• Distribution
#LRNAS2014
46. Missing pieces
A typical approach
!
• Deploy your app in a different machine/container/process
!
• Communicate them using your preferred approach
!
• REST
!
• ZeroMQ
!
• AMQP
#LRNAS2014
47. Missing pieces
OSGi Remote Services
!
• Near transparent extension to the Services model
!
• No explicit infrastructure API in user land
!
• Non mandatory technology (HTTP, JMS, RMI, …)
!
• Two OSGi specifications
!
• Remote Services: mechanics of transport
!
• Remote Service Admin: topology, service discovery
#LRNAS2014
65. Liferay
Can we apply this to Liferay?
!
• OSGi as one of the core techs of the product
!
• Split the product into small and independent focused
components/services
!
• Independent deployments
• Still within the same JVM
!
• Focused teams and efforts
