Red Hat OpenStack - Open Cloud InfrastructureAlex Baretto
This document provides an overview of Red Hat OpenStack. It discusses market dynamics driving adoption of cloud infrastructure, describes Red Hat's leadership and contributions to the OpenStack community, reviews the core OpenStack components, and demonstrates how an instance is launched across multiple OpenStack services. Red Hat brings enterprise-grade support, stability, and lifecycle management to OpenStack through Red Hat OpenStack.
This document provides an overview of a training course on using the OpenStack cloud computing platform. The course covers topics such as virtualization, OpenStack architecture, installation and configuration of key OpenStack services like Nova, Glance, Neutron, and Horizon. It is divided into 18 modules that teach concepts like the OpenStack infrastructure, deployment architectures, configuration of database, message broker and identity services, and hands-on use of the Horizon dashboard to launch instances. The course aims to help students implement both Red Hat OpenStack and self-deployed OpenStack platforms.
OpenStack Super Bootcamp Mirantis, 2012
The document outlines the steps in the OpenStack provisioning process:
1) A user requests VM provisioning via the Horizon dashboard or CLI which sends the request to Keystone for authentication.
2) Keystone validates the authentication data and provides a temporary token to Horizon.
3) Horizon sends the API request to nova-api which validates the token with Keystone before processing the request and saving details to the database. It then publishes the request to the scheduler queue.
OpenStack is open source software for creating private and public clouds. It controls large pools of computing, storage, and networking resources throughout a datacenter. The main OpenStack projects are Nova for computing as a service, which manages the lifecycle of virtual machine instances; and other projects that provide services like object storage, block storage, networking, and a dashboard. OpenStack uses a variety of virtualization technologies and works with popular enterprise and open source platforms.
The document provides an overview of the major OpenStack components from both a tenant and operator perspective. It describes the key services that OpenStack provides (Compute, Networking, Block Storage, Object Storage, Image Storage, Identity) and how each would be used and managed differently by tenants consuming infrastructure resources versus operators configuring and maintaining the cloud platform. It aims to explain the similarities and differences in how these services are experienced by tenants versus operators.

Introduction to Open Source Cloud Computing", Mark Hinkle, Senior Director Cloud Computing Community, Citrix
Very few trends in IT have generated as much buzz as cloud computing. This session will cut through the hype and clarify what cloud computing is, what the use cases are, and what open source software exists to build and manage clouds. The discussion will appeal to systems administrators, IT generalists, and developers...anybody who wants to create a cloud computing environment on their own hardware in their own data centers and deploy applications to this cloud.
One of the impediments to becoming an active technical contributor in the OpenStack community is setting up an efficient R&D environment which includes deploying a simple cloud. Using RDO-manager, get a basic cloud up and running with the fewest steps and minimal hardware so you can focus on the fun stuff - development
There is no doubt that Openstack represents one of the massive industry alignment towards the Open source cloud, Some even touting it to be the linux of cloud computing. But is it “THE” perfect solution ?
Vanilla Openstack is a “Myth”
The choice of Openstack as part of your cloud strategy purely depends on the kind of workload and the add-on features.
Openstack can be a serious contender especially for fresh deployments and applications that are being architected for cloud. But as the environment gets diverse(legacy integrations) Openstack can be tricky to integrate and maintain
One might require a vendor based Cloud management platform especially when the cloud strategy involves public clouds(AWS, Azure, GCE) and migration of application services across
No doubt it is fully open source, but it comes with learning curve, release cycles, Vendor specific driver integrations etc.
Interesting developments with respect to containers, docker, Kubernetes, Mesosphere etc will challenge Openstack
Openstack will no doubt will grow mature over next couple of years, until then, the hunt for the CMP continues...
Topics of interest :
to build a true hyper converged cloud ?
as an enterprise cloud management platform ?
public cloud ? (as a CSP)
Telco carrier grade cloud ?
VNF, MANO and SDN integrations

This document provides an overview and agenda for deploying OpenShift on OpenStack. It begins with a brief introduction to Platform as a Service (PaaS) and OpenShift. It then discusses the various flavors of OpenShift including the open source Origin project, public cloud service, and on-premise private cloud software. The remainder of the document focuses on deploying OpenShift on OpenStack using Heat templates, including an overview of Heat and its orchestration capabilities, the OpenShift architecture, and a demonstration of deploying OpenShift Enterprise templates with Heat.
OpenShift is a Platform-as-a-Service that provides development environments on demand using containers. It automates application lifecycles including build, deploy, and retirement. OpenShift uses containers to package applications and dependencies in a portable way. Red Hat addresses concerns around adopting containers at scale through OpenShift, which provides security, scalability, integration, management and certification capabilities. OpenShift runs on a user's choice of infrastructure and orchestrates applications across nodes using Kubernetes.
This talk covered the OpenStack basics that VMware Administrators need to be aware of to be successful in their deployments. We also had the Tesora team join us on stage to discuss the importance of Database-as-a-Service with the Trove project!
Tunning da jvm dos comandos às configuraçõesLuan Cestari
Já ficou em dúvida porque o Java você tem que compilar e mesmo assim ele não gera código nativo? Sabia que não existe somente uma implementação de JVM? Gostaria de saber como funciona alguns comportamentos internos que a JVM executa por abaixo dos panos enquanto compila/roda seu código? Se você respondeu um sim para essa palestra ou se você está curioso em saber o que mais sobre o assunto, venha asistir essa palestra. Vamos ver isso e muito muitos detalhes de tuning que você pode fazer e até analisar sua aplicação java.

Getting Started with SOA using SwitchYardLuan Cestari
This lecture will give an introduction of SOA, giving an background of history and an overview of its specifications. How does Service Component Architecture (SCA, which is an open source standard) can help you to create services that can exposed by an Enterprise Service Bus (ESB). The SwitchYard implement SCA specification and also bring integration of many features you have available at WildFly application server. It also aims to simplify the integration with its built-in tools (like IDE) and components. You might surprise yourself with the Open Source power.
O documento apresenta um guia sobre tunning da JVM em Java 8. Ele discute as principais mudanças na versão 8 da JVM como a remoção da Permgen e inclusão da Metaspace, novas ferramentas como jdeps, e técnicas de profiling e tunning como análise de uso de memória e frequência de GC.
Lightblue is an open source project that aims to simplify complex service architectures by providing a flexible and metadata-driven platform. It uses technologies like MongoDB for data storage and Hystrix for latency and fault tolerance. The presentation discusses how monolithic applications can evolve into interconnected services over time, causing problems like slowness, hardcoding, and difficulty deploying. Lightblue was created to address these issues by allowing services to be easily extended and deployed in cloud environments. Additional technologies discussed include various Java collections libraries and distributed computing frameworks.
The document introduces big data concepts and provides an overview of tools for working with big data. It discusses the characteristics of big data including volume, variety, velocity, and value. Popular tools like Hadoop, HDFS, and the Hadoop ecosystem are explained. The document also covers database history and why many database options now exist for big data.

Today, Linux is the primary platform for a majority
of cloud-based applications. As a case in point, an
October 2012 Wired magazine article cited a
report by Newvem which illustrated Linux's
dominant position, particularly pertaining to
Amazon Web Services:
At Wired’s request, Newvem — a company that
sells management services to Amazon cloud
customers — took at look at about 41,000 cloud
machines run by several hundred customers. Its
conclusion: Linux is twice as popular as Windows
on Amazon Web Services. It was running on 67
percent of machines, compared to Windows’ 33
percent.

This slide is derived from the Gartner
roadmap “From Virtualization to Cloud
Computing”, and indicates the various
levels of infrastructure enablement that
IT organizations are engaging in today.
Organizations often field more than one
virtual / cloud project may be doing IT
transformation to IaaS while at the same
time running Cloud program initiatives.
Focus has been on deriving economies
and flexibility at one level via server
virtualization and consolidation. Highly
distributed and sprawled virtual
environments that tend to result form
those initiatives require management
optimization and automation to be
efffectivley controlled.
Infrastructure as a Service (IaaS)
capabilities are then engaged to support
agile, self-service access to IT systems

IT must change and be able to address the questions
of the prior slide. If IT is not able to adapt and change
the business as their customer will go around IT and
buy services directly from public cloud and SaaS
providers which cannot be in the interest of IT and
the corporation overall because shadow IT will
sprawl
IT needs to provide the benefits of a public could
service by eliminating the potential negative sides of
public service like security concerns, governance,

http://slidesha.re/1gF0PEK
To set the proper context for our discussion, let’s take a look at
the three best known cloud service delivery models,
IaaS or Infrastructure as a Service,
PaaS or Platform as a Service,
And SaaS or Software as a Service.
With each of these some portion of the technology stack is
managed and controlled by the Cloud offering (whether public
or private), and the rest is responsibility of the customer of the
Cloud offering. They must manage and maintain the portion
of the stack that is not managed by the Cloud offering. The
benefit is that the customer can also CONTROL the design of
this portion of the stack.
For Infrastructure-as-a-Service, or IaaS, the customer must
manage and control everything from the Operating System up.
They must install the OS, the middleware, and the application
code. This ultimately becomes only a small reduction in effort
compared to bare-metal server management.

PaaS allows us to make this leap from a Craftwork methodology
to an Assembly Line methodology. PaaS both streamlines and
standardizes the Application Development process.
Instead of the unique, one-off processes that each application
project used to go through, Utilization of a PaaS allows the
deployment of a standardized methodology with a few distinct
repeatable steps.
Once the idea and budget are secured, then the App Dev team
just simply starts working with the PaaS to code, test, and
launch their application. PaaS provides the platform
environment that allows Developers to start coding immediately.
Server deployment, configuration and administration is all
largely automated. This reduces the burden on Operations and
reduces the delays that impact Development.
And many industry analysts agree that the utilization of PaaS is
going to be the key to allowing IT to be the demands of the
business.

In many ways, the RHOS and RHEL value propositions are identical with Red Hat
OpenStack (RHOS) being to OpenStack what Red Hat Enterprise Linux (RHEL) is to
Linux.
Red Hat has the proven capability of preparing and delivering an open source
distribution for enterprise use and providing a stable, secure, and common platform
that customers, ISV partners, IHV partners, and service provider partners can use to
test and certify their software and hardware solutions.
Operational competency necessary for maintain a stable platform with backported
bugfixes and features. World-class processes and procedures required for the
rigorous testing and QA necessary for enterprise-class products
Worldwide enterprise class support service with consulting and training services
Certified partner program
Guest certifications – include Microsoft Windows (SVVP)

http://slidesha.re/1gF0PEK
Tenants – Groups of users (could be a team, a whole
company, whatever you want), share resources
Users - ... users
Roles - admin or not is all it's used for so far
Tokens – auth to get a token. Token allows access to
all other OpenStack APIs.
133. OpenStack Identity (Keystone)
ReST API
keystone
Token
45
Identity
Services
http://slidesha.re/1gF0PEK
Presents a REST API (most services do)
Separate backends for tokens, identity, and services
Tokens – db, memcache
Identity – db, LDAP
Services – db, flat file backed

Horizontal Scaling with a load balancer
This pattern will be seen all over OpenStack.
HAProxy is a software load balancer that we support.
All services use the same storage backend (if
MySQL, use strategies to scale MySQL)

All horizon instances use the same OpenStack APIs
What's different: Session state shared via Django's
session engine, so whichever backends supported
there
default is local cache
others are memcached, db, db+caching, signed
cookies
139. OpenStack Orchestration (Heat)
●
Consumes all other OpenStack APIs
●
Important concept: template defined stacks
51
http://slidesha.re/1gF0PEK
Why Heat is awesome: Template defines your
application in terms of all of the resources needed
(instances, networks, database, load balancer)
Version your deployment like your software
Repeatable complex deployments that are fully
automated
AWS Cloudformation template compatible, but with
added OpenStack resources
AWS Cloudformation API
Also has an OpenStack API, native template syntax
in the works
Implements HA, auto scaling, was shown in keynote
this AM

ReST API / CFN API
heat-api

OpenStack APIs

52
http://slidesha.re/1gF0PEK
Heat-api – serves up the ReST API and/or CFN API
First time AMQP comes up. Explain it. Advanced
Message Queueing Protocol. Scalable messaging
between applications. We use Qpid.
Api talks to engine via AMQP
Engine does the real work of setting up the stack.
Makes many API calls to other OpenStack services
to set up all of the resources defined in the template

Meters
Collectors
http://slidesha.re/1gF0PEK
Meters – any type of usage data, transformed into
billable items by your own system
How much of a thing, how long, whatever makes
sense (CPU hours, bandwidth)
Notifications – Most projects emit usage notifications
via AMQP
Compute pollsters – poll for other data on compute
nodes
Central pollster – plug point, poll for data from
elsewhere
Collectors – collect meters from all of these places
and store it (in a db, mongodb, mysql/postgres)
145. OpenStack Metering (Ceilometer)
57
http://slidesha.re/1gF0PEK
Another view of the architecture, this one showing
actual services that run, including the API service
A few services funneling meters to the collector
Both collector and API access the backend store
Talk about scaling from this slide:
Horizontal scaling of API, compute pollsters, collector
147. OpenStack Object Storage (Swift)
●
Concepts
●
●
Containers – Organize Your Data
●
Objects – Your Data
●
59
Accounts
Ring – Internal Data Structure
http://slidesha.re/1gF0PEK
Object Storage ... store and retrieve blobs of data
Note that swift manages replicas of data across
multiple storage nodes
Ring internal, basically a distributed hash table, but
exposed to you as an admin. You tell swift info about
your deployment so it can build the ring
148. OpenStack Object Storage (Swift)
API

http://slidesha.re/1gF0PEK
Basically two node types, API nodes and storage
nodes
Storage nodes hold a subset of data, one of the
replicas of it
How does scaling work with these 2 node types?

account for added/removed nodes, rebalancing done
as needed
