PaaS & Deployment Models
PaaS deployed:
 public cloud
 private cloud
+ connect with existing
on-premises systems
= Hybrid cloud

6
Characteristics of PaaS
PaaS
Systems of Engagement
Support custom applications
Porting applications
Provide runtime environments
Rapid deployment mechanisms
Middleware capabilities
Provide services
Preconfigured
API management
Security capabilities
Developer tools
Operations capabilities

PaaS: Governance & Business Considerations
Business
Considerations
 Create a cross-functional team
 Evaluate the Cloud Service Agreement
 Plan for information security and risk
mitigation
 Examine costs and charges
 Assess software licensing of the CSP
 Consider compliance requirements
 Assure the use of PaaS will not result
in lock-in to a single CSP
Governance
Considerations
 Establish clear communication with
CSP for change management
 Provide appropriate security controls
 Understand processing and data
locations
 Ensure accuracy of system billing
 Control the capabilities of PaaS
developers and operators
 Ensure an appropriate exit process

CSCC Guide to Acquiring & Using PaaS Offerings
A reference to help enterprise IT & business decision
makers understand the technical and organizational
changes required to fully embrace PaaS offerings.
Guide to Acquiring & Using PaaS Offerings
Understand PaaS end-to-end application architecture
Understand how containers enable applications
Understand how services and microservices are used
Address integration between PaaS applications and existing systems
Ensure appropriate security components
Consider development tools and PaaS
Expect support for agile development and DevOps
Consider the deployment aspects of PaaS
“You must make application
developers more productive in
order for businesses to be in
business. So for me that's
where PaaS fits. It's supporting
this tremendous economic
pressure of the need for more
software to be developed
because business is
implemented through software
these days.“ Sam Ramji, CEO,
Cloud Foundry Foundation

Ensure appropriate security components
10 Steps to Manage Cloud Security
1. Ensure effective governance, risk & compliance
2. Audit operational & business processes
3. Manage people, roles & identities
4. Ensure proper protection of data & information
5. Enforce privacy policies
6. Assess the security provisions for cloud applications
7. Ensure cloud networks & connections are secure
8. Evaluate security controls on physical infrastructure
9. Manage security terms in the cloud service agreement
10. Understand the security requirements of the exit process
CSCC Security for Cloud Computing:
http://bit.ly/1aDu1P9
Security & data protection is critical.
Consider two types of capabilities:
1. Tools & facilities that help
developers build secure
application and services
2. Services & capabilities provided
by the PaaS systems to secure
and protect applications and
services

Expect support for agile development and DevOps
PaaS Features
 Test driven development
 Rapid allocation /
deallocation of resources
 Automation of build, test, QA
& deployment processes
 “Blue/green deployment”
 Provision of ready-to-use
services
 Operations capabilities that
address:
• Deployment/scalability
of services,
• Placement of runtime
instances
• Management of logs
 Visibility to service behavior
– alerts, monitoring, APIs

16
Consider the deployment aspects of PaaS
 Deployment: Public; Private; Hybrid
 on-premises / provider premises
 concerns over reliability & skill requirements
 applications, services, datasets
 separate considerations
 Questions of security risks & data protection requirements
 regulation
 Integration of applications in PaaS with other systems

17
Keys to Success
 Perform cost/benefit analysis
 Assess your security risk versus your innovation imperative
 Assess value provided by a given PaaS provider versus
alternatives
 Consider the long term viability of the PaaS provider ecosystem
 Consider portability both in terms of lock in and deployment
model as needs evolve
 Ensure integration between PaaS environment and on-premises
systems is straightforward and secure
 Consider transforming to Agile methods and DevOps processes
