Integration in the Age of DevOps

Cloud Native Architectures

• Trying to incorporate new technology?• Trying to copy what others (Netflix, Amazon) are

doing?• Tactical automation?• Created a “DevOps” team?• Exploring cloud services?• Build/deploy automation?• OpenSource?• Piecemeal integration?

How are you keeping up with change?

Cloud Native Architectures

Cloud Native Architectures

• Faster software delivery• Own database (data)• Faster innovation• Scalability• Right technology for the

problem• Test individual services• Isolation• Individual deployments

Microservices helps solve the problem of “how do we decouple our services and teams to move quickly at scale to deliver business value”

• If my services are isolated at the process level, I’m doing #microservices

I’m doing microservices if…

• If I use REST/Thrift/ProtoBuf instead of SOAP, I’m doing #microservices

• If I use JSON, I’m doing #microservices

• If I use Docker / SpringBoot / Dropwizard / embedded Jetty, I’m doing #microservices

Cloud Native Architectures

Fallacies of distributed computing• Reliable networking• Latency is zero• Bandwidth is infinite• Network is secure• Topology doesn’t change• Single administrator• Transport cost is zero• Network is homogenous

https://en.wikipedia.org/wiki/Fallacies_of_distributed_computing

Cloud Native ArchitecturesIf we have to take into account the network, do we still need integration?

Cloud Native ArchitecturesWe’ll just do reactive, event-driven distributed systems… still need integration?

Cloud Native Architectures

Yes; we need reliable integration!• REST, RPC• Messaging (ActiveMQ, JMS, AMQP, STOMP, Kafka,

etc)• Legacy (SOAP, mainframe, file processing,

proprietary)• Managed file processing• Streaming• Message transformation• EIPs

Heavy Lifting: Apache Camel for Microservices

Cloud Native Architectures

Apache Camel to the rescue!• Small Java library• Distributed-system swiss-army knife!• Powerful EIPs• Declarative DSL• Embeddable into any JVM (EAP, Karaf, Tomcat,

Spring Boot, Dropwizard, Wildfly Swarm, no container, etc)

• Very popular (200+ components for “dumb pipes”)

• “Smart endpoints, dumb pipes”• Endpoint does one thing well • Metadata used for further routing• Really “dynamic” with rules engine (eg,

Drools/BRMS)

Apache Camel features easy to use visual editorDynamic Routing

Apache Camel features easy to understand configREST DSLpublic class OrderProcessorRouteBuilder extends RouteBuilder {

@Override public void configure() throws Exception {

rest().post(“/order/socks”).description(“New Order for pair of socks”).consumes(“application/json”).route()

.to(“activemq:topic:newOrder”) .log(“received new order ${body.orderId}”)

.to(“ibatis:storeOrder?statementType=Insert”); }}

Cloud Native Architectures

Cloud Native Architectures

Typical problems developing microservices• How to run them all locally?• How to package them (dependency management)• How to test?• Vagrant? VirtualBox? VMs?• Specify configuration• Process isolation• Service discovery• Multiple versions?

Cloud Native ArchitecturesShared infrastructure platforms headaches• Different teams• Different rates of change• VM sprawl• Configuration drift• Isolation / multi-tenancy

• Performance• Real-time vs batch• Compliance• Security• Technology choices

Cloud Native Architectures

Immutable infrastructure/deploys• “we’ll just put it back in Ansible”• Avoid chucking binaries / configs together and

hope!• Cattle vs Pets• Don’t change it; replace it• System created fully from automation; avoid drift• Eliminate manual configuration/intervention

Docker / Linux Containers

Kubernetes

• Developer focused workflow• Enterprise ready• Higher level abstraction above containers for

delivering technology and business value• Build/deployment triggers• Software Defined Networking (SDN)• Docker native format/packaging• CLI/Web based tooling

OpenShift

Cloud Native Architectures

Fuse Integration Services for OpenShift• Set of tools for integration developers • Build/package your Fuse/Camel

services as Docker images• Run locally on CDK• Deploy on top of OpenShift• Plugs-in to your existing build/release

ecosystem (Jenkins/Maven/Nexus/Gitlab,etc)

• Manage them with Kubernetes/OpenShift

• Flat class loader JVMs• Take advantage of existing

investment into Karaf with additional options like “just enough app server” deployments

• Supports Spring, CDI, Blueprint

• Small VM run locally by developers

• Full access to Docker, Kubernetes, OpenShift

• Deploy your suite of microservices with ease!

• Uses Vagrant/VirtualBox

• Getting Started on Linux,

Mac or Windows!

How are you keeping up with change?

Cloud Native Architectures

• 100% open source, ASL 2.0• Technology agnostic (java,

nodejs, python, golang, etc)• Built upon decades of

industry practices• 1-click automation• Cloud native (on premise,

public cloud, hybrid)• Complex build/deploy

pipelines (human workflows, approvals, chatops, etc)

• Comprehensive integration inside/outside the platform

What if you could do all of this right now with an open-source platform?

• Docker native, built on top of Kubernetes API

• Out of the box CI/CD, management UI

• Logging, Metrics• ChatOps• API Management• iPaaS/Integration• Chaos Monkey• Lots and lots of

tooling/libraries to make developing cloud-native applications easier
