Five compelling reasons for creating a CICS Cloud are discussed: 1. Platforms allow hosting applications and services while viewing system activity from a single point. 2. Applications define related resources and dependencies as a single entity for easy deployment and status monitoring. 3. Policies protect the CICS environment by enforcing rules on applications. 4. Multi-versioning enables running multiple application versions concurrently and switching between versions without outages. 5. Measurement identifies tasks by application context for performance reporting by application and operation.

Five compelling reasons for
creating a CICS Cloud
Session 2809
Steve Zemblowski
zem@us.ibm.com

2. Session Abstract
So what does creating a CICS "Cloud" really mean?
And what exactly are these new CICS Cloud capabilities? How do
these new Applications and Platforms artifacts relate to existing
CICS technologies such as programs, transactions and regions?
Where do these new Policies fit in?
Most importantly, why would you do any of this? What value can
you expect to derive from creating a CICS Cloud architecture?
If you have ever asked yourself any of those questions, this
session will give you five compelling answers. If you ever
wondered what the CICS Cloud means in the real world, this
session if for you.

4. What is a Cloud?
• NIST Definition of Cloud Computing
Cloud computing is a model for enabling convenient, on-
demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage,
applications, and services) that can be rapidly provisioned and
released with minimal management effort or service provider
interaction.
• This cloud model promotes availability and is composed of five
essential characteristics, three service models, and four
deployment models.

7. What is a Cloud?
Essential Characteristics of a Cloud
How do we make CICS applications and management more agile?
CICS Explorer and the collection of
portfolio tools enable a greater
degree of automation
CICS put SOA at its core, delivering
greater integration and
connectivity across the enterprise
CICS is a first-class resource
manager built to efficiently
manage system and application
resources
CICS WLM, combined with z/OS,
enables CICS to rapidly respond to
fluctuating workload demands
CICS has extensive monitoring and
statistics to enable customers to
understand the cost of their
applications running in CICS
System z and z/OS
On-demand Self Service
Broad Network Access
Resource Pooling
Rapid Elasticity
Measured Service

applications in CICS more
easily?”
“How can I better manage
my CICS platform?”

8. What is a CICS Cloud?
• Bringing Cloud benefits to CICS
• CICS TS V5 delivers a pattern based, policy managed,
private CICS cloud environment, improving the agility of
CICS application deployments while reducing the risk of
implementation errors
• Enabling creation of private CICS clouds
• ‘The cloud infrastructure is provisioned for exclusive use by a
single organization comprising multiple consumers (e.g.,
business units)’
• NIST Special Publication 800-145, Sept 2011
12

9. Benefits of a CICS Platform
• What is a Platform?
• A runtime environment for hosting CICS applications
– Can also host resource bundles and policies
• Contains one or more regions types, each of which contains
one or more regions
14

10. Benefits of a CICS Platform…
• Platforms
• Defined, deployed and managed by the CICS Explorer using the
CICS Cloud perspective
– Displays platform status, region types and deployed applications
16

11. Benefits of a CICS Platform…
• Host applications and platform services
• View the status of platform system activity from a single point
• View the status of platform services and declared dependencies from a
single point
• Provision policies to all applications installed in the platform
• Dynamically add and remove services and dependencies while a
platform is installed
• Share systems between region types and platforms in a controlled way
• Scale hosted applications while the platform is already installed without
changes
18

12. Benefits of a CICS Application
• What is an application?
• A collection of related programs and other resources that together
perform a business operation
• In the CICS Cloud context an Application is a set of bundles
• Bundles can define application resources
– Library
– Program
– Transaction
– URIMAP
– WebService
• Bundles can also define platform resources
– FILE
– JVMSERVER
– PIPELINE
– TCPIPSERVICE
• Resource dependencies
• Policies
20

13. Benefits of a CICS Application…
• An Application can provide entry points for resource monitoring
• An associated operation can provide for resource monitoring
• An Application and its bundles are mapped to a Platform
• Application Binding specifies bundle to region type mapping
– Allows an Application definition to migrate to different environments
unchanged (development. test, production)
22

14. Benefits of a CICS Application…
• All the resources need for an application and their dependencies are
defined in the Application definition
• Manage and deploy the application as a single entity
• Easily determine the status of an application and its dependencies
• Measure the resource usage for an application
• Protect your CICS environment against problematic applications using
too many resources by applying threshold policies
• Deploy multiple versions of the application in the same Platform
• Consolidate different applications in the same Platform even if they have
clashing program names
24

15. Benefits of a Policy
• What is a Policy?
• Condition and action
• Action can be:
– Emit a message
– Emit a system event
– Abend the task
2626
Define a Policy
Threshold
breach
CICS Triggers an action
Abend EventMessage
Trigger an action
SQL
Files
Storage
CPU An XML Policy document defines
the threshold and action

16. Benefits of a Policy…
• Policy Rule Types
• Database request
• File request
• Program request
• Start request
• Storage request
• Syncpoint request
• Time
• Transient Data request
• Temporary Storage request

17. Benefits of a Policy…
• Protect the CICS TS platform from erroneous applications
• Identify early in the development lifecycle if an application meets
its service level agreements (SLAs)
• Enforce rules that applications must adhere to at run time

18. Benefits of Application Multi-Versioning
• What is Application multi-versioning
• Provide end user access to two or more versions of an
application hosted on the same platform by using the new
private PROGRAM and LIBRARY resources
• Quickly switch back and forth between two different versions
of an application using the AVAILABLE | UNAVAILABLE
state
• Route requests from users to different versions of an
application using the new INVOKE APPLICATION API

19. Benefits of Application Multi-Versioning…
• How is Application multi-versioning accomplished?
• New CICS private resources (only visible within an application)
– LIBRARY
– PROGRAM
– POLICY (may have different scopes depending where specified)
• Entry Points (names an Operation)
– Identifies an access point to an Application
• PROGRAM
• URIMAP BankingApp 1.0.0

Rolling back to
an older version
of an application
is a simple
operation - mark
the version as
‘unavailable”

22. Benefits of Application Multi-Versioning…
• Have more than one version of the application running
concurrently
• Maintain support for particular versions of applications for
migrating users
• Showcase new application features to a subset of your users
• Prepare and verify the installation of a new application without
deprovisioning the in-service application
• Bring a new version of the application into service with no service
outage
• Roll back versions of the application

23. Benefits of Application Measurement
• What is Application Measurement?
• Identification of tasks by their application context
– Application context consists of:
• Platform name
• Application Name
• Application Version
• Operation
• Allows monitoring of resource consumption by applications or
operations within the application
• Context available to custom dynamic routing programs

24. Benefits of Application Measurement…
• Allows for performance reporting by application and operation.
