Physical, virtual, containers. Public cloud, private cloud, hybrid cloud. IaaS, PaaS, SaaS. These are the choices that we're faced with when architecting a datacenter of today. And the choice is not one or the other; it is often a combination of many of these. How do we remain in control of our datacenters? How do we deploy and configure software, manage change across disparate systems, and enforce policy/security? How do we do this in a way that operations engineers and developers alike can rejoice in the processes and workflow?
In this talk, I will discuss the problems faced by the modern datacenter, and how a set of open source tools including Vagrant, Packer, Consul, and Terraform can be used to tame the rising complexity curve and provide solutions for these problems.

La infraestructura como código (IaC) es una de las prácticas relacionadas con la cultura DevOps que está cogiendo más tracción en el desarrollo de software y Terraform es una de las herramientas más recomendadas para ello.
Se suele relacionar sobre todo con la creación de infraestructura en los grandes servicios “Cloud” -AWS, Azure, Google Cloud,…- pero es además algo aplicable a otros aspectos de IT como podrían ser la creación de usuarios en servicios de terceros o propios (Github, bases de datos,…), configuración de dominios (Dyn, GoDaddy,…), configuración de alertas (Grafana, OpsGenie)…
Durante esta sesión se explicará su funcionamiento básico y veremos en directo despliegues en varias de estas plataformas.
Atmosphere Conference 2015: Taming the Modern DatacenterPROIDEA
Speaker: Seth Vargo
Language: English
Today we are plagued by hundreds of choices when architecting a modern data center. Should our machines be virtual or physical? Should we use containers or Docker? Should we use a public cloud provider or a private cloud provider? Which configuration management tool is best to use? What about IaaS, PaaS, and SaaS? It would be manageable if these were binary choices; however, we often find ourselves in a hybrid environment.
As more operations choices are added to your data center, whether through company acquisitions, a growing development team, or general technical debt, managing complexity between legacy and new systems becomes a nightmare. Yet the end goal is still the same — safely deploy your application to your infrastructure. We need to tame our data centers by managing change across systems, enforcing policies, and by establishing a workflow for both developers and operations engineers to build in a collaborative environment.
This talk will discuss the problems faced in the modern data center, and how a set of innovative open source tooling can be used to tame the rising complexity curve. Join me on an adventure with Vagrant, Consul, and Terraform as we take your data center from chaos to control.

Infrastructure-as-code: bridging the gap between Devs and OpsMykyta Protsenko
Ops are overwhelmed with support. Devs are mad because their cannot deploy the changes as fast as they want. Sounds familiar?
Infrastructure-as-code can make your life easier by empowering developers and reducing operations' routine toil. It can cut down the lead time for infrastructure provisioning from hours or even days to minutes.
This talk reviews several IaC tools and approaches, showing how to integrate them into continuous delivery pipeline. It covers the problems and challenges that engineers may face while working with infrastructure-as-code tools and provides a few hands-on recipes to address them.
Burn down the silos! Helping dev and ops gel on high availability websitesLindsay Holmwood
HA websites are where the rubber meets the road - at 200km/h. Traditional separation of dev and ops just doesn't cut it.
Everything is related to everything. Code relies on performant and resilient infrastructure, but highly performant infrastructure will only get a poorly written application so far. Worse still, root cause analysis in HA sites will more often than not identify problems that don't clearly belong to either devs or ops.
The two options are collaborate or die.
This talk will introduce 3 core principles for improving collaboration between operations and development teams: consistency, repeatability, and visibility. These principles will be investigated with real world case studies and associated technologies audience members can start using now. In particular, there will be a focus on:
- fast provisioning of test environments with configuration management
- reliable and repeatable automated deployments
- application and infrastructure visibility with statistics collection, logging, and visualisation
Abstract: At DataRobot we deal with automation challenges every day. This talk will give insight into how we use Python tools built around Ansible, Terraform, and Docker to solve real-world problems in infrastructure and automation.

Speaker: Jacob Aae Mikkelsen
Once you have successfully developped your application in Grails, Ratpack or your other favorite framework, you would like to see it deployed as fast and painless as possible, right?
This talk will cover some of the supporting cast members of a succesful modern infrastructure, that developers can understand and use efficiently, and with good DevOps practices.
Key elements are
Docker
Infrastructure as Code
Container Orchestration
The demo-goods will hopefully be on our side, as this talk includes quite some live demos!
Listen up, developers. You are not special. Your infrastructure is not a beautiful and unique snowflake. You have the same tech debt as everyone else. This is a talk about a better way to build and manage infrastructure: Terraform Modules. It goes over how to build infrastructure as code, package that code into reusable modules, design clean and flexible APIs for those modules, write automated tests for the modules, and combine multiple modules into an end-to-end techs tack in minutes.

Automating your Infrastructure Deployment with AWS CloudFormation and AWS Ops...Amazon Web Services
When you’re building a new application you need to get new features out fast. Managing your application’s infrastructure as well as responding to changing conditions can be cumbersome and error prone if you rely on manual processes. Treating your infrastructure as code allows you to provision and update complex environments in a predictable manner. You can also offer a pre-defined catalogue of environments for development, testing and experimentation, unlocking your ability to innovate. This session will walk through practical examples and live demonstrations using AWS CloudFormation, AWS OpsWorks, orchestration engines and source control systems to automate your infrastructure deployment and maintenance.
Speaker: Richard Busby, Solutions Architect, Amazon Web Services
In this presentation, I am going to briefly talk about 'what cloud is' and highlight the various types of cloud (IaaS, PaaS, SaaS). The bulk of the talk will be about using the fog gem using IaaS.

OpenStack Horizon: Controlling the Cloud using DjangoDavid Lapsley
OpenStack is an open source cloud computing project that is implemented predominantly in Python. OpenStack’s goal is to provide the "ubiquitous open source cloud computing platform for public and private clouds”. The OpenStack project was launched by Rackspace and NASA in July 2010. Since then the project has gained considerable momentum with over 200 companies joining the project, and the launch of commercial services and products that use OpenStack.
The OpenStack Horizon project provides a web-based User Interface to OpenStack services. It is constructed in two parts: (1) a core set of libraries for implementing a Dashboard; (2) a reference dashboard implementation that uses the core set of libraries. Customization is a core part of the Horizon Framework. The framework enables developers to construct their own dashboards, panel groups and panels, and enables them to assemble them together via a common navigation/presentation framework.
In this presentation, we will provide a brief introduction to OpenStack and Horizon. Then we will dive into the details of Horizon. We will review Horizon’s overall architecture and how it integrates with other OpenStack services. We will look at some of Horizon’s interesting features and describe how to get started developing with Horizon. Finally, we will discuss some of the current challenges facing Horizon and some future directions.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Accelerate your Kubernetes clusters with Varnish CachingThijs Feryn
A presentation about the usage and availability of Varnish on Kubernetes. This talk explores the capabilities of Varnish caching and shows how to use the Varnish Helm chart to deploy it to Kubernetes.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
22. Today
• Poten'ally elas'c set of servers of varying sizes
• Push towards SoA
• SaaS for everything
• More internet connected devices than ever before => higher traffic
23. What do we need?
• Zero to deployed in one command
• Resiliency through distributed systems
• Autoscaling, autohealing
• Beder teamwork through codified knowledge
28. Build, combine, and launch
infrastructure safely and efficiently.

29. What If I asked you to…
• create a completely isolated second environment to run an applica'on
(staging, QA, dev, etc.)?
• deploy a complex new applica'on?
• update an exis'ng complex applica'on?
• document how our infrastructure is architected?
• delegate some ops to smaller teams? (Core IT vs. App IT)
30. What If I asked you to…
• create a completely isolated second environment to run an applica'on
(staging, QA, dev, etc.)? One command.
• deploy a complex new applica'on? Code it, diff it, pull request.
• update an exis'ng complex applica'on? Code it, diff it, pull request.
• document how our infrastructure is architected? Read the code.
• delegate some ops to smaller teams? (Core IT vs. App IT) Modules,
code reviews.
32. Terraform
• Create infrastructure with code: servers, load balancers, databases, email
providers, etc.
• One command to create, update infrastructure.
• Preview changes to infrastructure, save diffs.
• Use code + diffs to treat infrastructure change just like code change:
make a pull request, show the differences, review it, and accept.
• Break infrastructure into modules to encourage/allow teamwork without
risking stability.

37. Infrastructure as Code
• Human friendly config, JSON compa'ble
• Text format makes it version-‐able, VCS-‐friendly
• Declara've
• Infrastructure as code on a level not before possible
38. Zero to Done in One Command
Terraform Apply
$ terraform apply
digitalocean_droplet.web: Creating…
dnsimple_record.hello: Creating…
Apply complete! Resources: 2 added, 0 changed, 0 destroyed.
39. Zero to Done in One Command
• Idempotent
• Highly parallelized
• Will only do what the plan says
43. Safely Change/Iterate
• Plan shows you what will happen
• Save plans to guarantee what will happen
• Plans show reasons for certain ac'ons (such as re-‐create)
• Prior to Terraform: Operators had to “divine” change ordering,
paralleliza'on, rollout effect.
44. Workflow
• Make code changes
• `terraform plan`
• Pull request with code changes + plan to make changes
• Review and merge
• `terraform apply pr1234.pplan`
45. Knowledge Sharing: Modules
Terraform Plan
module “consul” {
source = “github.com/hashicorp/consul/terraform/aws”
servers = 3
}
resource "dnsimple_record" "hello" {
domain = "example.com"
name = "test"
value = “${module.consul.server_address}”
type = "A"
}
46. Knowledge Sharing: Modules
Terraform Plan
module “consul” {
source = “github.com/hashicorp/consul/terraform/aws”
servers = 3
}
resource "dnsimple_record" "hello" {
domain = "example.com"
name = "test"
value = “${module.consul.server_address}”
type = "A"
}
47. Knowledge Sharing: Remote Modules
Terraform Plan
resource “terraform_remote_state” “consul” {
type = “atlas”
name = “hashicorp/consul”
}
resource "dnsimple_record" "hello" {
domain = "example.com"
name = "test"
value = “${terraform_remote_state.consul.outputs.server_address}”
type = "A"
}
48. Knowledge Sharing: Modules
• Self-‐contained infrastructure components
• Allows delega'on of responsibility to mul'ple teams
• Some teams create modules, other teams consume modules
• Remote modules let teams share outputs, but not affect infrastructure
49. Terraform
• Zero to fully deployed in one command
• Change/maintain infrastructure predictably
• Teamwork-‐oriented workflow to infrastructure
• Goal: Sta'c deploy/provisioning of infrastructure. Real'me monitoring,
discovery, configura'on provided by Consul (discussed next).
52. Ques'ons that Consul Answers
• Where is the service foo? (ex. Where is the database?)
• What is the health status of service foo?
• What is the health status of the machine/node foo?
• What is the list of all currently running machines?
• What is the configura'on of service foo?
• Is anyone else currently performing opera'on foo?
54. Service Discovery
Service Discovery via DNS or HTTP
$ dig web-frontend.service.consul. +short
10.0.3.89
10.0.1.46
$ curl http://localhost:8500/v1/catalog/service/web-frontend
[{
“Node”: “node-e818f1”,
“Address”: “10.0.3.89”,
“ServiceID”: “web-frontend”,
…
}]
55. Service Discovery
• DNS is legacy-‐friendly. No applica'on changes required.
• HTTP returns rich metadata.
• Discover both internal and external services
(such as service providers)
60. Key/Value Storage
Serng and Gerng a Key
$ curl –X PUT –d ‘bar’ http://localhost:8500/v1/kv/foo
true
$ curl http://localhost:8500/v1/kv/foo?raw
bar
61. Key/Value Storage
• Highly available storage of configura'on.
• Turn knobs without big configura'on management process.
• Watch keys (long poll) for changes
• ACLs on key/value to protect sensi've informa'on
67. Events, Exec, Watches
Dispatching Custom Events
$ consul event deploy 6DF7FE
…
$ consul watch -type event -name deploy /usr/bin/deploy.sh
…
$ consul exec -service web /usr/bin/deploy.sh
…
68. Events, Exec, Watches
• Powerful orchestra'on tools
• Pros/cons to each approach, use the right tool for the job
• All approaches proven to scale to thousands of agents
69. Easiest Distributed System Deploy
Deploy Consul to AWS
$ terraform apply github.com/hashicorp/consul/terraform/aws
var.servers
The number of Consul servers to launch.
Default: 3
Enter a value: 3
…
70. Easiest Distributed System Deploy
Deploy Consul to AWS (manually)
$ consul agent -atlas-join
-atlas=USERNAME/NAME
-atlas-token=API_TOKEN
71. Workflow
• Server is started (via Terraform, etc.)
• Consul agent is started, joins cluster
• Star'ng services (ex. web app) query Consul for configura'on
• Once healthy, services are discovered via DNS!
72. Opera'onal Bullet Points
• Leader elec'on via Ra9
• Gossip protocol for aliveness
• Three consistency models: default, consistent, and stale
• Encryp'on, ACLs available
• Real world usage to thousands of agents per datacenter
