Cloud computing the best choice

• Scalability issues with web applications based on
  RDBMS NoSQL are increasing every passing day
• Cloud computing methodologies
• Counter issues that arise with growing amount of
  hardware , devices their platforms
• Manage the deluge of ever increasing data
• Combat the requirements of improved networking
  capabilities
• Match the requirements of large databases the
  complexity of computations

4
Planning a Cloud Based System

• A competent Cloud platform supports
• Multiple Locations
• Monitoring of Load
• Auto Scaling
• Content Delivery
• Caching
• The Cloud aims to
• Reduce the response time
• provide a constant monitoring for the system and
  enable auto scaling

5
Cloud Strategies

• Target to improve page load times
• Separate static content from the deployment
• Distribute data and content over various
  instances
• Integrate smart caching techniques to enable sync
  between nodes

Choosing the Service - Stateless or Stateful ?

• Stateless Service
• Provides a response after the user request
• Requires no further attention
• A perfect load balance for redundant services is
  needed
• Stateful Service
• Subsequent requests to the service depend on the
  results of the first request
• A single action typically involves more than one
  request
• Requires deployment of more application servers
  and web servers in the system
• Resource allocation needs meticulous planning

8
Choosing the Database SQL or NoSQL?

• RDBMS
• For a system that is not data intensive
• NoSQL (requires a document / key based database )
• For a system with huge volumes of data to ensure
  simplicity of design, and ease of data retrieval
• In many circumstances both these could be used
  together to get the best of both

9
The Cloud System Type - Computing Intensive or
Data Intensive?

• Data intensive system
• Any node in the cloud for
• Data retrieval
• Data processing
• A good approach to real time data
• Computing intensive node
• Different nodes for data retrieval and data
  processing

10
The Keys to the Success of a Cloud Implementation

• Making all services and the server stateless
• To implement a stateless session on the web
  server good choices are cookie based sessions,
  distributed cache sessions or database sessions
• Stateless implementations also ensure
  indempotence for ensuring safe and smooth data
  retrievals
•  Planning prudent data transfers by avoiding
  unnecessary transfers to keep a check on the
  amount of data transferred

11
On A Parting Note.

• Irrespective of the deployment method chosen,
  Private Cloud, Public Cloud or a Hybrid Cloud a
  cloud implementation is bound to improve the
  agility of the system, give device and location
  independence, assure improvements in
  performances, ensure easy maintenance and provide
  reliable security
• And the most important fact remains that they are
  scalable and scale on demand
