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 computing is a new paradigm in computing and can provide significant revenue opportunities for system integrators

The revenue from business process services delivered through cloud is expected to be 14

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

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
