Deployment Guide: Install F5 BIG-IP, LBaaS, and validate Red Hat OpenStack Platform CloudIntroductionToday’s software-defined economy requires businesses to move faster than their competitors.Speed and agility are critical to keeping up with competitive demands for new applications, aswell as to maintaining existing infrastructure. IT organizations must respond aggressively tomeet business needs and the private cloud can be a primary tool to achieve this objective. Notsurprisingly, then, organizations are accelerating their journey to the cloud.OpenStack for CloudSoftware developers are turning to the OpenStack platform for cloud computing. Its openAPIs, flexible architecture, and large commercial ecosystem help enterprises compete in acompletely new paradigm of software development. OpenStack is rapidly becoming thedominant cloud platform for delivering Infrastructure as a Service (IaaS). As OpenStack cloudsincreasingly host mission-critical production applications, advanced application deliveryservices for layers 4–7 are becoming essential. Enterprise customers deploying newapplications with these services expect them to be available when they transition to a cloudbased architecture.Planning an OpenStack ArchitectureF5 is the leading supplier of advanced application delivery services across data center, public,and private clouds, including those powered by OpenStack. F5 partnered with Red Hat to helpcustomers accelerate OpenStack deployments. OpenStack and F5 application delivery servicesand platforms combine to bring production-grade services to OpenStack-hosted applications.F5 application delivery services can be accessed in two ways within OpenStack: throughNeutron Load Balancing as a Service v2.0 (LBaaSv2) and HEAT orchestration. With thecombination of OpenStack, F5, and Red Hat, enterprises can transition from traditional datacenters to private clouds faster and more efficiently.Seamless Migration to the CloudThe F5 private cloud solution package for OpenStack offers agile application services. Theseservices are delivered by NetOps in an automated and continuous integration environmentwithout compromising corporate security or reliability standards. The solution packageenables efficient collaboration between DevOps/application owners and NetOps, whilereducing proliferation of shadow IT. Seamless migration of applications from development toproduction clouds and consistent delivery of application services facilitates infrastructure-ascode initiatives. The solution package also offers simplified private cloud rollout andoperational confidence with tested and certified solutions, backed by enterprise-gradesupport and documentation.4
Deployment Guide: Install F5 BIG-IP, LBaaS, and validate Red Hat OpenStack Platform CloudF5 Private Cloud Solution Package for OpenStackThe F5 private cloud solution package for OpenStack provides joint certification and testingwith Red Hat to orchestrate F5 BIG-IP Application Delivery Controllers (ADCs) withOpenStack Networking services. The validated solutions and use cases are based on customerrequirements utilizing BIG-IP ADC and OpenStack integrations. F5’s OpenStack LBaaSv2integration provides under-the-cloud L4–L7 services for OpenStack Networking tenants. F5’sOpenStack orchestration (HEAT) templates provide over-the-cloud, single-tenant onboardingof BIG-IP virtual edition (VE) ADC clusters and F5 iApps templating for application servicesdeployment.F5 ADCs can help ease the transition as applications migrate from traditional architectures tothe private cloud. The many existing applications currently utilizing F5 ADCs, applicationpolicies, and the F5 iRules scripting language, can maintain business logic in the migration tothe cloud. For other applications, BIG-IP virtual edition ADCs offer a dynamic pivot for servicesas they are chained and refactored into new architectures.The OpenStack private cloud solution package documented here -- Migrating Workloads toOpenStack Private Cloud -- is the first of seven use cases. This use case, one of the mostcommon, uses features available in existing OpenStack integrations. The F5 solution validatesthis use case based on tests utilizing the OpenStack integration. These tests have beenvalidated and certified by Red Hat and published as part of F5’s open source solution. Thisenables our customers and their partners to easily deploy and accelerate OpenStackdeployment with F5 application delivery services.Testing the solutionOpenStack installations are highly configurable and vary greatly. New OpenStack versions arereleased every six months, creating the need for continuous testing and validation of oursolutions. This F5 solution package for the OpenStack private cloud was tested with a series ofOpenStack cloud deployments and Tempest tests suites while using Red Hat OpenStackPlatform (OSP) version 9, an OpenStack distribution. Red Hat, which maintains and supportsthe OSP, has its own test suite for LBaaSv2 certifications. F5 maintains its LBaaSv2 certificationwith Red Hat as part of its partnership. Red Hat also provides input and validates use casetests for private clouds against the company’s own OSP cloud deployments. The successfulcompletion of this test with Red Hat OSP version 9 forms the basis of a documented andvalidated solution supported by both F5 and Red Hat. See Red Hat’s Customer Portal for moreinformation on LBaaS v2.0 official support certification.Use Case: Migrate Existing Workloads to OpenStack Private CloudThis first use case focuses on migrating existing workloads to an OpenStack private cloud. Insupport of this goal, this deployment guide provides instructions for installing and validating a5

The migration presentedhere is based on tested deployments of Red Hat OSPv9 with F5 LBaaSv2 services, utilizingBIGIP i5800 ADC devices and a BIG-IP VE instance deployed within an OpenStack tenant.Validation and certification were performed at the F5 Labs in San Jose, California, inpartnership with Red Hat. Additional information regarding the Red Hat OSP can be found inthe Red Hat OpenStack Platform documentation; F5 has extensive documentation for itsOpenStack solutions, in addition to the open source code on GitHub. Details on the F5 iSeriesare provided on www.f5.com.The F5 private cloud solution package for OpenStack comprises an edge deploymentarchitecture, represented by Figure 1, below. It uses OpenStack networking provider networkswith F5 agents deployed in global routed mode, as well as F5 agents deployed in L2 adjacentmode for micro-segmentation and tenant networking. The BIG-IP hardware devices in thediagram below are cloud-ready i5800 ADCs. The BIG-IP VE tenants are software ADCs, whichuse the F5 BIG-IQ Centralized Management license manager to manually license the fixedlicense pools and provisioning.Figure 1: F5 OpenStack deployment test architectureTables 1 and 2 show the F5 components and build of material included in the private cloudsolution package for OpenStack.6

For the complete Red Hat OpenStack Platform documentation suite, see the RedHat OpenStack Platform Documentation.ComponentsThe Private Cloud Solution Package for OpenStack features multiple components from F5 andRed Hat. This chapter provides an overview of each component. The Red Hat OpenStackPlatform IaaS cloud is implemented as a collection of interacting services that controlcompute, storage, and networking resources. The cloud can be managed with a web-baseddashboard or command-line clients, which allow administrators to control, provision, andautomate OpenStack resources. OpenStack also has an extensive API, which is also available toall cloud users.Figure 2 provides a high-level overview of the OpenStack core services and their relationshipwith each other. Only those components pertinent to the presented use case are covered indetail in this deployment guide.8

Networking1.1.1. OpenStack Networking (neutron)OpenStack Networking creates and manages a virtual networking infrastructure in theOpenStack cloud. Infrastructure elements include networks, subnets, and routers.OpenStack Networking provides cloud administrators with the flexibility to decide whichindividual services to run on which physical systems. All service daemons can be run on asingle physical host for evaluation purposes. Alternatively, each service can have a uniquephysical host, or be replicated across multiple hosts to provide redundancy. BecauseOpenStack Networking is software-defined, it can react in real-time to changing networkneeds, such as creation and assignment of new IP addresses. OpenStack Networkingadvantages include: Users can create networks, control traffic, and connect servers and devices to one ormore networks.Flexible networking models can adapt to the network volume and tenancy.IP addresses can be dedicated or floating, where floating IPs can be used for dynamictraffic rerouting.10
