OpenStack

PaaS, OpenStack, & cloud adoption 

 

 

IT Challenges 

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

 

 

What is a cloud workload ?

 

 

• There are many types of workloads in the datacenter, solution must serve all of them
• Pets or cattle? Lots of pets, lots of cattle too
• Portability – environment has to be portable
• Solution needs to be highly available and reduce/eliminate single points of failure
• Create an efficient system to allow repeatable and auditable processes
• Needs to meet corporate security and compliance requirements
• Ability to charge back the LOBs
• Support for IPv6

 

 

 

 

 

Which emerging technologies and standards are most important to watch

• Inefficient utilization of resources.
• Resource saturation.
• Lack of elasticity and scalability.
• Lack of security and governance.
• Frequent outages.
• Bad or no tenant management.
• Other very bad things.

 

Why Openstack   and its Overview

Provides a complete end-to-end infrastructure management  solution for OpenStack business planning, system deployment  and ongoing operations.
 Core features:

1. API, CLI and Dashboard driven deployments
2.  Cloud deployment modeling
3.   Deployment and provisioning
4.  Instrumentation framework

 

 

What is OpenStack?

• OpenStack is an open source, Python based, cloud operating system. It is designed to control large scale, multi tenant cloud deployments
• OpenStack is built through a set of distributed services which control compute, storage, network, identity management, orchestration, and much more

 

• Comprised of several open source sub-projects
• Provides all of the building blocks to create an Infrastructure-as-a-Service cloud

• Designed and architected to replicate public cloud infrastructure, e.g. Amazon AWS
• Governed by the vendor agnostic OpenStack Foundation
• Enormous market momentum with significant investment from major player

 

 

 

Features of Openstack 

• Deploying OpenStack to  bare metal
•  OpenStack community adopted
•  Providing visual status of core   services and cloud infrastructure
•  Offering platform extensibility
•  Providing integration via well  known APIs
•  Is cloud operator focused!
•  Naturally resilient and scalable

Use Cases for OpenStack Today
Main use cases:

DevOps – important to move content from dev to ops quickly
Software development – test environment, ability to bring up and tear down sophisticated topologies and configuration
Elasticity/scalability – users who need to burst and gain large scale quickly
Batch processing/HPC
Web companies –
NFV
Early Adopters:
Small groups
Strong IT skills set can “figure stuff out”
Fairly simple regulatory environment
