69 OpenStack Architecture OpenStack is made up of individual autonomous components All of which are designed to scale-out to accommodate throughput and availability OpenStack is considered more of a framework, that relies on drivers and plugins Largely written in Python and is heavily dependent on Linux
70 OpenStack Identity Service (Keystone) Keystone provides a common authentication and authorisation store for OpenStack Responsible for users, their roles, and to which project(s) they belong to Provides a catalogue of all other OpenStack services All OpenStack services typically rely on Keystone to verify a user s request
71 OpenStack Compute (Nova) Nova is responsible for the lifecycle of running instances within OpenStack Manages multiple different hypervisor types via drivers, e.g- Red Hat Enterprise Linux (+KVM) VMware vsphere
72 OpenStack Image Service (Glance) Glance provides a mechanism for the storage and retrieval of disk images/templates Supports a wide variety of image formats, including qcow2, vmdk, ami, and ovf Many different backend storage options for images, including Swift
73 OpenStack Object Store (Swift) Swift provides a mechanism for storing and retrieving arbitrary unstructured data Provides an object based interface via a RESTful/HTTP-based API Highly fault-tolerant with replication, self-healing, and load-balancing Architected to be implemented using commodity compute and storage
74 OpenStack Networking (Neutron) Neutron is responsible for providing networking to running instances within OpenStack Provides an API for defining, configuring, and using networks Relies on a plugin architecture for implementation of networks, examples include- Open vswitch (default in Red Hat s distribution) Cisco, PLUMgrid, VMware NSX, Arista, Mellanox, Brocade, etc.
75 OpenStack Volume Service (Cinder) Cinder provides block storage to instances running within OpenStack Used for providing persistent and/or additional storage Relies on a plugin/driver architecture for implementation, examples include- Red Hat Storage (GlusterFS, Ceph), IBM XIV, HP Leftland, 3PAR, etc.
76 OpenStack Orchestration (Heat) Heat facilitates the creation of application stacks made from multiple resources Stacks are imported as a descriptive template language Heat manages the automated orchestration of resources and their dependencies Allows for dynamic scaling of applications based on configurable metrics
77 OpenStack Telemetry (Ceilometer) Ceilometer is a central collection of metering and monitoring data Primarily used for chargeback of resource usage Ceilometer consumes data from the other components - e.g. via agents Architecture is completely extensible - meter what you want to - expose via API
78 OpenStack Dashboard (Horizon) Horizon is OpenStack s web-based self-service portal Sits on-top of all of the other OpenStack components via API interaction Provides a subset of underlying functionality Examples include: instance creation, network configuration, block storage attachment Exposes an administrative extension for basic tasks, e.g. user creation
79 IaaS+ Components
80 Why does the world need OpenStack? Cloud is widely seen as the next-generation IT delivery model Agile & Flexible Utility-based on-demand consumption Self-service driving down administrative overhead and maintenance Public clouds are setting the benchmark of how IT could be delivered to users Not all organisations are ready for public cloud Applications are being written differently today- More tolerant of failure Making use of scale-out architecture
81 Major issues with traditional infrastructure Our data is too large Volumes of data are being generated at unprecedented levels Most of this data is unstructured Service requests are too large More and more devices are coming online Tablets, phones, laptops, BYOD generation Crucially, applications weren t written to cope with the demand! Traditional infrastructure capabilities are being exhausted Service uptime, QoS, KPI s and SLA s are slipping
82 Workloads are evolving Traditional Workloads Cloud-enabled Workloads Typically each tier resides on a single machine Doesn t tolerate any downtime Relies on underlying infrastructure for availability Applications scale-up, not out Workload resides across multiple machines Applications built to tolerate failure Does not rely on underlying infrastructure Applications scale-out, not up
83 So, how does OpenStack fit in? OpenStack is typically suitable for the following use cases A public cloud-like Infrastructure-as-a-Service cloud platform Internal Infrastructure on Demand - private cloud Test and Development environments - e.g. sandbox Cloud service provider platform - reselling compute, network & storage Building a scale-out platform for cloud-enabled workloads Web-scale applications, e.g. NetFlix-like, photo/video-streaming Academic or pharma workloads, e.g. genetic sequencing, HPC/Scientific Computing
