Do you need the most reliable, secure, and cost-effective on-premise cloud platform? Look no further: a cloud based on WebSphere and Linux on System z is the answer. This presentation traces the evolution of successful server consolidation to Linux on System z, from brute-force physical moves to virtual topology to sophisticated workload placement. We'll cover techniques and considerations to ensure a rich, dense, enterprise environment. The material is derived from interactions with our enterprise mainframe customers running world-class data centers.
We will briefly describe the new Enterprise Cloud System that unites leading IBM software, storage, and server technologies into one simple, flexible, and secure factory-integrated solution.
We will show examples of System z based cloud environments which provide everything you expect from System z: extreme reliability, secure, geo-dispersed, high performance clouds. We will describe application development and deployment patterns that both help and hurt in a virtualized cloud environment. From the admin perspective we will explore heap and GC tuning, idle server tuning, and stacking options. We will also present a very effective performance tuning approach for large scale virtualized environments.
We also present WebSphere Liberty profile performance in a virtualized environment, relative to a traditional WebSphere application server.

This is an updated talk on Cloud Computing and the Citrix Cloud Center.
From time to time the Citrix CTO Office is asked to give presentations at these and other events. I'm interested in any/all feedback from the Citrix and Cloud communities.
Cloud computing provides on-demand access to shared computing resources like networks, servers, storage, applications and services over the internet. It has characteristics like massive scale, resilience, virtualization, and low cost software. Common service models include Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Virtualization allows multiple virtual machines to run on a single physical machine. Cloud computing enables companies to save costs by using infrastructure on demand rather than owning their own data centers and servers. Commercial cloud offerings provide services like storage, computing resources, and platforms.
Virtualization allows multiple operating systems and applications to run simultaneously on a single physical machine. It provides benefits such as running different operating systems, easier software installation through virtual appliances, testing and disaster recovery using snapshots, and infrastructure consolidation to reduce hardware costs. Virtualization works by allocating resources like memory, processing power, and storage to virtual machines through a hypervisor. Early virtualization technologies date back to the 1960s but it became widely adopted in the 2000s with advances in hypervisor software.
Cloud computing allows users to access shared computing resources over the internet. It utilizes virtualization which involves partitioning physical resources and allocating them to virtual machines. This improves resource utilization, enables multi-tenancy, and makes resources scalable and flexible. Virtualization allows multiple operating systems and applications to run concurrently on a single physical server through virtual machines. It provides benefits like hardware independence, migration of virtual machines, and better fault isolation. Security challenges in virtualized cloud environments include issues around scaling, diversity, identity management and sensitive data lifetime.
VMware Infrastructure is evolving into a virtual datacenter operating system (VDC-OS) that aggregates server, storage, and network hardware into shared resources and allocates these efficiently among applications. This provides built-in services like availability, security, and performance scalability to all applications. The VDC-OS allows more efficient consolidation than traditional operating systems and helps address challenges of complex, siloed, and inefficient infrastructures. Key features of the VDC-OS include virtual services for compute, storage, networking, and cloud resources that improve scalability, availability, security and manageability.

Cloud computing refers to using internet-based computing resources that are dynamically scalable and often virtualized. Amazon Web Services (AWS) provides cloud computing services including compute power (EC2), storage (S3), content delivery (CloudFront), databases (SimpleDB), messaging (SQS), and other tools. GigaVox implemented S3, EC2 and SQS in 2006, creating a scalable infrastructure for less than $100 that would have cost thousands to build themselves.
This document discusses virtualization and cloud computing. It defines virtualization as creating an illusion of computer hardware or resources. Cloud computing is defined as on-demand network access to configurable computing resources. The traditional server concept of dedicating physical servers is described as well as the benefits of the virtual server concept, including scalability, fault tolerance, and efficiency. Virtualization techniques like full virtualization, paravirtualization, and hardware-assisted virtualization are covered. Hypervisors are defined as the software that creates virtual machines, and the differences between type 1 and type 2 hypervisors are explained. KVM is provided as an example of a type 2 hypervisor for Linux.
Virtualization abstracts the underlying physical hardware and allows multiple virtual machines to run on the same server. This provides benefits like server consolidation, increased hardware utilization, and improved security. While virtualization works well for most applications, some resource-intensive or real-time applications may have performance limitations in a virtualized environment. Virtualization is now being applied at larger scales through cloud computing, where virtual machines and services can be provisioned on-demand from large-scale data centers.
This document discusses cloud computing and job opportunities in the cloud computing sector. It begins by defining cloud computing and describing its characteristics, service models, and deployment models. It then discusses key cloud technologies like Amazon Web Services, cloud storage, and utility computing using Amazon EC2. The document outlines several commercial cloud offerings and concerns about cloud computing. Finally, it proposes four courses of study to acquire skills in cloud infrastructure, servers, storage, and virtualization, along with the technologies, certifications, and job roles associated with each course.

6. The Traditional Server
Concept
System Administrators often talk about servers as a
whole unit that includes the hardware, the OS, the
storage, and the applications.
Servers are often referred to by their function i.e. the
Exchange server, the SQL server, the File server,
etc.
If the File server fills up, or the Exchange server
becomes overtaxed, then the System Administrators
must add in a new server.

7. The Traditional Server
Concept
Unless there are multiple servers, if a service
experiences a hardware failure, then the
service is down.
System Admins can implement clusters of
servers to make them more fault tolerant.
However, even clusters have limits on their
scalability, and not all applications work in a
clustered environment.

8. The Traditional Server
Concept
Pros Cons
Easy to conceptualize Expensive to acquire and
Fairly easy to deploy maintain hardware
Easy to backup Not very scalable
Virtually any Difficult to replicate
application/service can be Redundancy is difficult to
run from this type of setup implement
Vulnerable to hardware
outages
In many cases, processor is
under-utilized

11. The Virtual Server Concept
Virtualservers seek to encapsulate the
server software away from the hardware
This includes the OS, the applications, and the
storage for that server.
Servers end up as mere files stored on a
physical box, or in enterprise storage.
A virtual server can be serviced by one or
more hosts, and one host may house more
than one virtual server.
20090909_VirtualizationAndCloud 11
12. The Virtual Server Concept
Virtual servers can still be referred to by their
function i.e. email server, database server,
etc.
If the environment is built correctly, virtual
servers will not be affected by the loss of a
host.
Hosts may be removed and introduced
almost at will to accommodate maintenance.
20090909_VirtualizationAndCloud 12
13. The Virtual Server Concept
Virtual servers can be scaled out easily.
If the administrators find that the resources supporting a
virtual server are being taxed too much, they can adjust the
amount of resources allocated to that virtual server
Server templates can be created in a virtual
environment to be used to create multiple, identical
virtual servers
Virtual servers themselves can be migrated from
host to host almost at will.
20090909_VirtualizationAndCloud 13
14. The Virtual Server Concept
Pros Cons
Resource pooling Slightly harder to
Highly redundant conceptualize
Highly available Slightly more costly (must
buy hardware, OS, Apps,
Rapidly deploy new servers
and now the abstraction
Easy to deploy layer)
Reconfigurable while
services are running
Optimizes physical
resources by doing more
with less
20090909_VirtualizationAndCloud 14
15. Virtualization Status
Offerings from many companies
e.g. VMware, Microsoft, Sun, ...
Hardware support
Fits well with the move to 64 bit (very large
memories) multi-core (concurrency) processors.
Intel VT (Virtualization Technology) provides
hardware to support the Virtual Machine Monitor
layer
Virtualization is now a well-established
technology 20090909_VirtualizationAndCloud 15

18. Forbes' Solution
Host the web site in Amazon's EC2 Elastic
Compute Cloud
Provision new servers every day, and
deprovision them every night
Pay just $0.10* per server per hour
* more for higher capacity servers
Let Amazon worry about the hardware!
20090909_VirtualizationAndCloud 18
19. Cloud computing takes
virtualization to the next step
You don’t have to own the hardware
You “rent” it as needed from a cloud
There are public clouds
e.g. Amazon EC2, and now many others
(Microsoft, IBM, Sun, and others ...)
A company can create a private one
With more control over security, etc.
20090909_VirtualizationAndCloud 19
20. Goal 1 – Cost Control
Cost
Many systems have variable demands
Batch processing (e.g. New York Times)
Web sites with peaks (e.g. Forbes)
Startups with unknown demand (e.g. the
Cash for Clunkers program)
Reduce risk
Don't need to buy hardware until you need it
20090909_VirtualizationAndCloud 20
21. Goal 2 - Business Agility
More than scalability - elasticity!
Ely Lilly in rapidly changing health care
business
Used to take 3 - 4 months to give a department a
server cluster, then they would hoard it!
Using EC2, about 5 minutes!
And they give it back when they are done!
Scaling back is as important as scaling up
20090909_VirtualizationAndCloud 21
22. Goal 3 - Stick to Our Business
Most
companies don't WANT to do system
administration
Forbes says:
We are is a publishing company, not a software
company
But beware:
Do you really save much on sys admin?
You don't have the hardware, but you still need to
manage the OS!
20090909_VirtualizationAndCloud 22
23. How Cloud Computing Works
Various providers let you create virtual servers
Set up an account, perhaps just with a credit card
You create virtual servers ("virtualization")
Choose the OS and software each "instance" will have
It will run on a large server farm located somewhere
You can instantiate more on a few minutes' notice
You can shut down instances in a minute or so
They send you a bill for what you use
20090909_VirtualizationAndCloud 23
24. Any Nasty Details?
(loads of them!)
How do I pick a provider?
Am I locked in to a provider?
Where do I put my data?
What happens to my data when I shut down?
How do I log in to my server?
How do I keep others from logging in (security)?
How do I get an IP address?
Etc.

25. And One Really Important Caveat*
* Cloud BootCamp March 2009
20090909_VirtualizationAndCloud 25
26. (footnote)
How come Amazon?
Grew out of efforts to manage Amazon’s own
services
(Each time you get a page from Amazon, over a
hundred servers are involved)
See reference Amazon Architecture on their
service design concepts
They
got so good at it that they launched
Amazon Web Services (AWS) as a product
20090909_VirtualizationAndCloud 26
27. Cloud Computing Status
Seems to be rapidly becoming a mainstream
practice
Numerous providers
Amazon EC2 imitators ...
Just about every major industry name
IBM, Sun, Microsoft, ...
Major buzz at industry meetings
20090909_VirtualizationAndCloud 27
28. So What’s the Take-Away?
There
seems to be a major revolution
underway in how we manage hardware
Specify (machine per service or one big and
machine with many virtual servers software
?
Purchase (own it yourself or rent from a
public cloud)
Use (always-on, or flexible provisioning as
needed ...)
We may need to rethink both our
research and teaching
20090909_VirtualizationAndCloud 28
29. For UWF:
What About Research?
The Eucalyptus Project
From University of California Santa Barbara
An open source collection of tools to build your
own cloud
Linux using Xen for virtualization
Anapparently open research area: handling
data
Regular databases apparently don't scale well
Especially hard to make elastic (scale up / scale
down)
20090909_VirtualizationAndCloud 29
30. For UWF:
What About Teaching?
Our
graduates should know about cloud
computing / virtualization
It will be useful for some applications, though not
for all
But what are the right learning objectives?
Awareness (its there ...)
Mechanics (here’s how to instantiate a server ...)
Design (how to make a scalable service ...)
???
20090909_VirtualizationAndCloud 30
31. For Fall 2009 ...
Currently
developing a Virtualization / Cloud
Computing “module”
1 – 2 class sessions plus an exercise
Target courses (November):
COP 6990 – Multi-Process Computing (Simmons)
CTS 4817 – Web Server Administration
(Owsnicki-Klewe)
Objectives
Awareness and mechanics of EC2
