The webinar introduces the Red Hat and Cisco OpenStack solution, discussing data center workload trends and the transition from traditional systems to OpenStack. It outlines the capabilities of OpenStack, including its components and features like self-service portals and microservices architecture, while emphasizing the importance of Red Hat Enterprise Linux as a distribution for OpenStack. Additionally, it highlights the integration of OpenStack with Cisco UCS for dynamic workload management and the advantages of using the Red Hat distribution for cloud applications.

5. DATA CENTER WORKLOAD TRENDS

6. Changes in Data Center Workloads
Moving from homogeneous workloads to heterogeneous
• Yay! More workloads means more goals achieved
• Ohh… How to manage the infrastructure of all these workloads
Moving from ticket/request based systems to self-service portals
• Yay! Users provision themselves!
• Ohh… Need to pick/maintain self-service portals
Microservices instead of 3-tierd Applications
• Yay! Allows for rapid development, deployment, iteration!
• Ohh… Requires much more agile deployments than traditional virtualization/IT
currently provides
Advent of OpenStack
• Yay! Open source cloud operating system!
• Ohh… Very difficult to deploy from source.

9. Traditional Virtualization: Applications!
Application
Applications have traditionally
been tightly coupled with the
server they were installed on.
With the advent of virtualization, this
paradigm had not changed.
Applications were tightly coupled with
the VM they were installed on.
Application

10. Pets Versus Cattle
Traditional VM Cloud Instance
Pet Cattle
Lives Forever Terminated frequently
Persistent storage Storage disappears when instance
terminated
OS Installed manually or cloned Instantiated from image
Based on ISO installation CD Based on pre-created image
Very individualized Tied to limited number of images

12. Cloud Applications: Resilient
Application
shard
shard
shard
shard
• Applications are written
so that their load is
easily self-distributed
(referred often as
Sharding… that’s with a
“d”)
• Applications are
generally stateless. The
loss of any instance or
node results in no
service disruption or
data loss

13. Cloud Applications
• Cloud Apps generally don’t
need vMotion/Live Migration,
they were made to be run on
“redshirt” instances
• Instances can be removed
without disruption to the
application
• Applications generally go for
“eventual consistency”, rather
than immediate consistency

14. OPENSTACK

15. What Is OpenStack?
“OpenStack is a cloud operating system that controls large pools of compute,
storage, and networking resources throughout a datacenter, all managed
through a dashboard that gives administrators control while empowering their
users to provision resources through a web interface.” –Openstack.org

16. Basics of OpenStack
An Open Sourced platform
(Apache 2.0 License)
Comprised of a collection of
“programs” responsible for
various aspects
Functionality is abstracted at
the program level, details
handled locally
Consumed via API/GUI/CLI
