Cloud Revolution
1950’s
• Era of Mainframe Computing
• Shared a single processor and storage unit for multiple users
1970’s
• Era of Virtual Machine/Server
• Virtual machine with operating systems brought the revolution in
IT industry
1990s
• Concept of load balancing and use of physical devices in shared
mode
2000s
• Era of Cloud Computing

• Cloud is essentially utility
computing
• Automated services
• “Pay per usage” - services
are billed as consumed
• “Accessible Anywhere”-
enabled via the internet
• Elasticity in amount of
services consumed
• Transition from capital
expense to operating
expense
Cloud Computing – The Era of Virtualization

Software
• SaaS (software‐as‐a‐service)
• Applications available as an on-demand
service
• End‐user applications
Platform
• PaaS (platform‐as‐a‐service)
• IT and developer tools for database and
testing environments to build applications
• Development or deployment activities
Infrastructure
• IaaS (infrastructure‐as‐a‐service)
• Computing, Storage and Hosting Services
• Network administrators
Common Example
Different Services Offered by Cloud
• Email Service
• Salesforce
• Goto-Meeting
• Microsoft Office 365
• Google Apps
• Database Server
• Application Development
• Automation or Load Testing
• OS
• Directory Services
• Virtual Servers
• Cloud Storage
• Application Hosting Environment

Architecture of Cloud Computing

Current Trends
• Majority of Startups are using a cloud-based infrastructure
• AWS leads in public cloud. Interest is building for Azure and
Google.
• In terms of users and revenues, Software-as-a-Service has the
biggest share
• Developers are flocking to PaaS for their enterprise
applications. Microsoft Azure is most successful with its PaaS
model.
• Hybrid cloud is the popular choice
• The challenge of cloud security is abating
• Next-generation IT shapes up as Cloud + DevOps + Self-
Service IT

• Gartner predicts a continued
strong growth in public cloud
services, with a CAGR of 17% year
on year through 2017
• SaaS is rapidly gaining adoption in
enterprises, leading Gartner to
forecast that more than 50% of
enterprises will have some form
of SaaS-based application
strategy
• Highest Growth rate is observed
in cloud infrastructure services
• Forrester, another analyst firm,
predicts cloud will generate
greater revenue potential which
can clearly be seen from AWS and
Rackspace
Future of Cloud Computing: Gartner Survey

Cloud: Fundamental Shift in IT

• Economic Benefits
– People
– Hardware
– Pay as you go
– Time to Market
• Improves service availability
• Less worry about outages
• 3 in 10 midsize firms adopting public cloud in the next five years
• Easy integration for any app
• Scale up and down quickly
• Trusted Advisor
• Global becomes standard
Cloud: How will it Benefit a Startup?
• Operational Benefits
– Reduced Cost
– Increased Storage
– Automation
– Flexibility
– Better Mobility
– Better use of IT staff

Cloud: Startup Program
• Various cloud providers have increased their focus on startup
engagements and provide various program which benefit a
startup
– Amazon Web Services (AWS): AWS Activate program for startups
– IBM: SoftLayer, an IBM company, has a startup incubator called
Catalyst
– Google Cloud Platform: The Google cloud platform startup pack
favorable for startup
– Microsoft Azure: Microsoft BizSpark program is one of the oldest
and most popular program among the technology startups
– Rackspace: Rackspace is one of the early cloud service providers to
offer special packages for startups

• Situation
– A small Size startup that needs to develop,
monitor and manage its internal systems
• Challenge
– The company does not have its own IT team,
and IT knowledge is minimal
• Solution
– The company decides a managed service
model based on cloud
– By handing over responsibility to a third
party, the startup benefits from lower capital
costs (no IT personnel recruited, no new
hardware/software required, no licensing
issues)
– The company is not distracted from focusing
on its core responsibility i.e. growing the
business
Case Study 1- Startup Company

Case Study 2- Hybrid Model
• Situation
– A manufacturing company that mostly uses Microsoft technologies
and tools
– The company has some legacy systems built on other platforms
– A significant portion of company’s IT budget is allocated to maintaining
applications on-premise server
• Challenge
– Deploying new on-premise applications takes too long
– Infrastructure is used inefficiently
– Less critical applications typically get low amount of attention from
the IT staff
– Company has to follow compliance and standard
– Company wants performance and scalability solutions for better
customer experience
– Some application and data should be accessible from intranet

Case Study 2- Hybrid Model
• Solution
– Company opted for Hybrid cloud model which solved all the previously
mentioned challenges
– Enabled them to maximize the strengths of both hosted and on-
premise models

Case Study 3- Idea Generation
• Situation
– When a company decides upon the branding and identity for a new
product, it creates dozens of alternatives, and picks the best of these
for testing and refinement. Generating the raw ideas that feed
subsequent development processes, plays a critical role in innovation.
• Challenge
– Small and medium businesses need to compete with larger enterprises
in developing custom B2B products & enterprise applications for web &
mobile, at a rapid pace, yet at a fraction of cost involved so far

Case Study 3- Idea Generation
• Solution
– PaaS technology allows developers to develop, test and deploy their
software in one comprehensive environment
– Single platform environment frees the developer from the need to
tailor their applications to work on various OS and hardware
– Clients benefit from Zero overheads and keeping 100% focus on
Product Development & Go-to-market
PaaS Model Benefits

Evaluating the Cloud Readiness of Your Application
• Is your app a web app?
• Is your app native .NET/Java?
• Do you use any interop to other technologies?
• What database type do you use?
• What kind of management/monitoring tools do you use on your
app?
• Can you assess the costs of cloud deployment for your app?
• Determine the security risks that cloud deployment will reveal?
• Upgrade costs?
• Flexibility and transferability?
• Scalability and redundancy capabilities?

Cloud Based Development Best Practices- I
• Design your application for cloud
– Choose IaaS, PaaS or SaaS at appropriate places
– Data storage options
– Apply design patterns specific to cloud
– Everything is a service: Use RESTful APIs
– Decompose applications into logical components
– Use cloud provided services
– Technology choice
– Load balancing and Auto-scaling strategy
– Stateless web server
– Using distributed caching if required
– Use CDN to edge-cache static file assets (images and scripts)
– Security at every layer

Cloud Based Development Best Practices- II
• Identify your strategy and approach to cloud
• Evaluate various options for hosting the application- Public, Private
community, Enterprise or Hybrid
• Design for taking care for failures
• Compute partitioning
• Data consistency
• Data partitioning
• Data replication and synchronization
• Instrumentation and telemetry
• Automate everything

Cloud Based Design – Auto Scaling Architecture

Cloud Based Design - Failover MultiCloud
Architecture

Summary
• This is right time for Startups to outperform the big
players by leveraging cloud offerings
• There are varieties of cloud models available for
different business solutions. One should have an
understanding of one’s business requirement and
map it with different offerings provided by cloud
providers
• Good technology partner who maps your business
requirement with the cloud offerings is the need of
today
