OpenStack – an API OpenStack – an open source software project OpenStack – a private cloud platform OpenStack components Compute Object storage Block storage Network Common OpenStack use cases Public hosting High-performance computing Rapid application development Network Function Virtualization Drafting an initial deployment plan The role of the Architect The design document The deployment plan Your first OpenStack deployment Writing the initial deployment plan Hardware Network addressing Configuration notes Requirements Installing OpenStack Installation instructions Verifying the installation Next steps Summary Further reading Chapter 2: Architecting the Cloud Picking an OpenStack distribution Running from the trunk Community distributions Commercially supported distributions Compute hardware considerations Hypervisor selection Sizing the hardware to match the workload Considerations for performance-intensive workloads Network design Providing network segmentation Software-defined networking Physical network design Storage design Ephemeral storage Block storage Object storage Expanding the initial deployment Updating the design document Cloud controller Compute node Management network Provider network Tenant network Updating the deployment plan Installing OpenStack with the new configuration Summary Further reading Chapter 3: Planning for Failure and Success Building a highly available control plane About failure and success High availability patterns for the control plane Active/passive service configuration Active/active service configuration OpenStack service specifics OpenStack web services Database services The message bus Compute, storage, and network agents Regions, cells, and availability zones Regions Cells Availability zones Updating the design document Planning the physical architecture Updating the physical architecture design Implementing HA in the lab deployment Provisioning a second controller Installing the Pacemaker resource manager Installing and configuring HAProxy Additional API service configuration Summary Further reading Chapter 4: Building the Deployment Pipeline Dealing with Infrastructure as a Software Eating the elephant Writing the tests first Always be deploying Using configuration management for deployment Using the community modules Assigning roles Choosing a starting point Test infrastructure Types of testing Writing the tests Running the tests Putting the pipeline together Setting up the CI server Installing Git Installing a Puppet master Installing Jenkins Creating the composition layer Starting our Puppet modules Defining the first role and profile Running the first build Writing the tests Assigning the first role to a system Installing Keystone Fully automating the pipeline Summary Further reading Chapter 5: Building to Operate Logging, monitoring, and alerting Logging Monitoring What to monitor Monitoring practices Monitoring availability Monitoring performance Monitoring resource usage Alerting Active monitoring Services Processes HA control cluster A dashboard example The future of OpenStack troubleshooting and Artificial Intelligence-driven operations Capacity planning Planning your city Tracking usage and analyzing growth Flavor sizing and compute server hardware selection Backups and recovery Infrastructure backup architecture Backup strategies – what to back up Workload backup architecture Planning for disaster recovery Summary  Further reading Chapter 6: Integrating the Platform IdM integration Authentication and authorization in OpenStack Configuring Keystone with split assignment and identity Provisioning workflows The Horizon user interface Using REST APIs Provisioning with templates Metering and billing Listening to OpenStack Using the notification subsystem Consuming events from Ceilometer Reading meters in Ceilometer Introducing OpenStack Gnocchi Updating the design document Writing requirements Testing requirements Summary Further reading Chapter 7: Securing the Cloud Security zones within OpenStack Software vulnerabilities Instance software security and patching Infrastructure host security and patching Patching OpenStack code Patching the operating system Red Hat Enterprise Linux and CentOS Canonical Ubuntu-based operating systems Software repository management Hardening hypervisors Standard Linux hardening practices and hypervisors SELinux and AppArmor sVirt SELinux and sVirt in action SSL and certificate management Assessing risk Best practices for endpoint security Examples Auditing OpenStack CADF details Using CADF with OpenStack Log aggregation and analysis Summary Further reading Chapter 8: OpenStack Use Cases Network Function Virtualization (NFV) / Telco Cloud What is NFV? The difference between NFV and Software-Defined Networking (SDN) NFV architecture European Telecommunication Standards Institute (ETSI) Open Platform for NFV (OPNFV) OpenStack's role in NFV Top requirements from Telcos for NFV on OpenStack Performance High availability, resiliency, and scaling Handling the rest of NFV management with NFVO and VNFM The NFV use case is solid and growing Big data and scientific compute use case Storing Data – Hadoop Combining Data - MapReduce Hadoop-as-a-Service, OpenStack Sahara Example architecture for Hadoop Use Case CERN – Big Data and OpenStack at Scale Edge Computing use case What is Cloud Edge Computing? Real-life use cases for Edge Computing Current challenges with Cloud Edge Computing Summary Chapter 9: Containers What are containers? So why are people so excited about containers? How do I manage containers? Containers and OpenStack Docker on OpenStack Kubernetes on OpenStack OpenStack container-related projects Nova-Docker Integration with Neutron – Kuryr Integration with Cinder – Fuxi Magnum Zun OpenStack On Containers Kolla Helm Summary Chapter 10: Conclusion Emerging trends in OpenStack Moving up the stack Building the roadmap Introducing new features Releasing new versions Summary Further reading Other Books You May Enjoy Index
