OpenStack is a cloud operating system designed to manage compute, storage, and networking resources in data centers through a dashboard interface. It includes core services like Nova for compute, Cinder for block storage, and Neutron for networking, among others, while supporting a modular architecture for users to provision resources. OpenStack also enables multi-cloud environments, addressing challenges in data management and compatibility to boost flexibility and scalability for enterprises, particularly in sectors like telecommunications.

A ringside view of services, technology and architecture

2. OPENSTACK
ARCHITECTURE
The OpenStack Components

3. OpenStack Defined
■ OpenStack is a cloud operating system that controls large pool of compute, storage,
and networking resources throughout a datacenter.
■ The resources are all managed through a dashboard that gives administrators
control
■ Empowers the Users to provision resources through a web interface
■ IaaS
■ Modular Architecture

7. Dashboard Service: Horizon
■ A dashboard provides administrators and users a GUI to OpenStack services
including Nova, Swift, Keystone etc.
■ Allows Users and Administrators of the environment to interact with and manage the
various functional components

8. Compute Service: Nova
■ To host and manage cloud computing systems, manages the lifecycle of instances
■ Major part of Infrastructure-as-a-Service(IAAS)
■ Interacts with Identity, Image Service and Dashboard
■ Spawning, Scheduling and decommissioning of virtual machines on demand

9. Identity Service: Keystone
■ Keystone is the identity service used for Authentication
■ Set of assigned user rights and privileges for performing a specific set of operations
■ A User token issued by Keystone includes a list of that User’s roles. Services that
determine how to interpret those rules

10. Image Service: Glance
■ The Glance project provides services for discovering, registering, and retrieving
virtual machine images
■ Glance has a RESTful API that allows querying of VM image metadata as well as
retrieval of the actual image

11. Block Storage: Cinder
■ Architected to provide traditional block level storage resources to other OpenStack
services
■ Presents persistent block-level storage volumes for use with OpenStack Nova
compute instances
■ Manages the creation, attaching and detaching of these volumes between the
storage system and different host servers

12. Object Storage: Swift
■ A distributed object storage system designed to scale from a single machine to
thousands of servers
■ Optimized for multi-tenancy and high concurrency
■ Ideal for backups, web and mobile content, and any other unstructured data that
can grow without bound
■ Swift provides a simple, REST-based API

13. Monitoring Service: Ceilometer
■ OpenStack Telemetry provides common infrastructure to collect usage and
performance measurements within an OpenStack Cloud
■ Its primary initial targets are monitoring and metering
■ Ceilometer was promoted from an incubation stage to an integrated component of
OpenStack

14. Networking Service: Neutron
■ Network as a Service (NaaS)
■ Provides REST APIs manage network connections for the resources managed by
other OpenStack services
■ Complete control over the following network resources in OpenStack (Networks,
ports, subnets)
■ Build complex network topologies

15. Orchestration Service: Heat
■ Heat provides a template based orchestration for describing a cloud application by executing
appropriate OpenStack API calls to generate running cloud applications
■ Templates specify the relationships between resources (e.g. this volume is connected to this
server). This enables Heat to call out to the OpenStack APIs to create all of your infrastructure in
the correct order to completely launch your application.
■ The software integrates other components of OpenStack. The templates allow creation of most
OpenStack resource types (such as instances, floating ips, volumes, security groups, users, etc), as
well as some more advanced functionality such as instance high availability, instance auto scaling,
and nested stacks
■ Heat primarily manages infrastructure, but the templates integrate well with software configuration
management tools such as Puppet and Ansible
■ Multiple composite cloud applications by using either the native HOT template format or AWS
CloudFormation template through OpenStack native REST API and a CloudFormation-compatible
Query API

20. OPENSTACK IN MULTI
CLOUD ENVIRONMENT

21. OpenStack and Multi-Cloud
Environment
■ Enterprises with OpenStack private cloud can adopt multi-cloud platform
■ Challenges need to be tackled around data management and platform compatibility
■ Multi-cloud computing enables an enterprise to tap into a diverse set of cloud
services
■ Users might choose GCP for high-performance computing, AWS for its broad portfolio
of features and Oracle for its database as a service offerings

22. Success in Multi-Cloud Deployment
■ Enterprise IT teams must evolve their management practices
■ Teams need to orchestrate workloads and translate virtual network configuration
files
■ Ansible facilitates moving workloads between OpenStack and a major public cloud
■ Industry is also facilitating by standardizing images for both VMs and containers
■ Because of varied set of services and APIs, onus is on the IT teams for compatibility
■ Data management is critical to avoid performance bottlenecks
■ Deployment to S3 compatibility to maintain a single REST interface across all clouds

23. Success in Multi-Cloud Deployment
(contd.)
■ Avoid transfer of whole data sets between the public cloud and the OpenStack cloud
as it is time consuming and costly
■ Replicate data in each cloud platform to obviate latency
■ Run OpenStack private cloud with high-bandwidth fiber links
■ Among major public cloud providers, Google is focused to have multi-cloud
environment with OpenStack
