MOVING TOWARDS CLOUD ERA
THE WORLD HAS SEEN 3 WAVES, EACH RESULTING IN A NEW ERA AND THE CURRENT WAVE USHERS INTO THE INFORMATION ERA
Each of these 3 waves have had mini waves which significantly changed the momentum of that era

The industrial era started with a number of factories being established on river banks which were used as the source of CAPTIVE power

The invention of large scale electric production and the distribution was one of the mini waves in the industrial era which exponentially increased the momentum

There are 3 flavors to cloud computing: Infrastructure as a Service (IaaS), Platform as a Service ( PaaS) and Software as a Service ( SaaS)
CLOUD COMPUTING FLAVORS
SaaS
PaaS
IaaS
Level of sharing Business Value
Network and systems resources
Architecture, design, framework,
components environment
Business agility and integration
Business processes, user
domains etc
Reduced operation cost
Reduced development cost, faster time to market
The level of sharing and business value increases as we move up the cloud value chain (from IaaS to PaaS and SaaS)

Enterprise Cloud Computing Landscape
• Market size and opportunities
• Adoption areas
• Organizational changes
15
IT spending on cloud based services reached $150 billion in 2014
MARKET SIZE AND OPPORTUNITIES

Cloud Migration Best Practices
• Cloud adoption phases
• Best practices
18
1. Establish quantifiable goals and objectives
Focus on improving the business capability
EXPLORATION BEST PRACTICES
Improve Business Capability
Reduce Development
Cost
Reduce Operational
Cost
• Faster time-to-market• Scalability and availability • Improve user experience• Capability led innovation
• Reduce application maintenance cost
• Remove application duplication
• Reduce cost of developing new capability
• Reduce hardware and software costs
• Reduce cost of maintaining the IT infrastructure
• Capex vs Opex
Lower cost alone should not be the goal
19
Financial: Current cost models, existing contracts etc.
Regulatory: Data security and ownership, compliance and other related requirements
Organizational: Current skillsets and competencies, vendors, team structures
Service: Existing service level agreements, contracts in place etc.
Technical: Technology stacks, software licenses, integration requirements
Operational: DevOps, governance, risk management etc.
2. Existing organizational constraints are important
EXPLORATION BEST PRACTICES
Document, plan and incorporate constraints
20
3. Cloud platforms are very diverse ( SaaS, PaaS, IaaS) - Choose wisely
Vendor lock and constraints increase from IaaS, PaaS to SaaS

4. Do not lose focus on business value of the applicationTechnical possibilities alone may not provide the optimal rationalization plan
RATIONALIZATION BEST PRACTICES

IT Efficiency• Operational Cost• Potential Cost• Standardization• Reuse• Operational Maturity

Business value should be the key driver
Efficiency / Suitability
22
5. Do not de-risk to the extent of making the program irrelevantAdopting a rational level of risk paves the way for high returns
RATIONALIZATION BEST PRACTICES
• Pick lowest risk application (something we can live without – in the worst case)• Also end up being the lowest impact application
General tendency when moving to the cloud
Downside is that even with great success, only minimal positive impact will be realized
We recommend a balanced approach, where a representative group of applications are picked including low impact low-risk, but also some high impact applications that can validate the promise of cloud computing
Balance low hanging fruits and complex migrations
23
6. Interdependencies of applicationsRATIONALIZATION BEST PRACTICES
Take a holistic view of applications and identify where the application fits in, in the grand scheme
Sources: Wikipedia, dsmweb.org, lattix.com
End points remediation can be a huge undertaking
24
7. Vendor lock-in is not always a bad thing
RATIONALIZATION BEST PRACTICES
Clearly understand the upside and downside of avoiding vendor lock-in
Be pragmatic about vendor lock in
• Provides portability across cloud platforms• Protects against platform cost increases
• Additional effort• More expensive to build, operate and maintain• Increased time-to-market• Leveraging only the lowest common services• Inability to leverage platform specific services
PROS CONS
25
8. Focus on cloud pipelines and continuous delivery from the onset
OPTIMIZATION BEST PRACTICES
Continuous delivery reduces time-to-market and increases operational agility
Transitioning to a Continuous Delivery model can yield huge benefits
26
9. Re-think security modelsA tiered security model is the key; leverage shared security model, application and infrastructure
security capabilities of cloud
OPTIMIZATION BEST PRACTICES
Rationalize and simplify security models
• Plan for hybrid enterprise architecture• Federated SSO• Identity providers and Service Providers• Common authorization model
Application Security
• Encryption at rest and in motion• Key management• Data residency
Data Security
• Virtual private clouds and subnets• Access frameworks (IAM)
Infrastructure Security
