- 16. CLOUD COMPUTING 16 Dr. NGPASC COIMBATORE | INDIA What is Cloud Computing?
- 17. CLOUD COMPUTING 17 Dr. NGPASC COIMBATORE | INDIA Cloud Computing is the use of network of remote servers hosted on the Internet to store, manage & process data rather than a local server
- 18. CLOUD COMPUTING 18 Dr. NGPASC COIMBATORE | INDIA Cloud Computing It is the delivery of computing services (Servers, DB., N/W, S/W etc.) over the Internet
- 19. CLOUD COMPUTING 19 Dr. NGPASC COIMBATORE | INDIA Cloud Computing It is the delivery of computing services (Servers, DB., N/W, S/W etc.) over the Internet Pay for what U use
- 20. CLOUD COMPUTING 20 Dr. NGPASC COIMBATORE | INDIA Cloud Computing It is the delivery of computing services (Servers, DB., N/W, S/W etc.) over the Internet Pay for the usage alone Storing / Accessing the data over the Internet Companies offering these services are called as, Cloud providers

EXAMPLES OF CLOUD COMPUTING 21 Dr. NGPASC COIMBATORE | INDIA Communication Skype, Whatsapp Productivity MS Office 365, Gmail Data Storage Dropbox, Facebook, Gmail Business Processes Salesforce, Hubspot Application Development Amazon Lumberyard Big Data Analytics Hadoop, Cassandra Social Networking MySpace, LinkedIn, Twitter
- 22. CHARACTERISTICS OF CLOUD COMPUTING 22 Dr. NGPASC COIMBATORE | INDIA On-demand Self-service Broad Network Access Multi-tenancy & Resource Pooling Rapid Elasticity Measured Service with Pay-per-use
- 23. PROPERTIES OF CLOUD COMPUTING 23 Dr. NGPASC COIMBATORE | INDIA Cloud Services • Cloud storage - distributed resources - act as single unit • Highly fault tolerant through redundancy - distribution of data • Eventually consistent with regard to data replicas • Collaboration in cloud
- 25. HISTORY OF CLOUD COMPUTING 25 Dr. NGPASC COIMBATORE | INDIA
- 26. GARTNER REPORT 26 Dr. NGPASC COIMBATORE | INDIA • Cloud Computing - foundation of digital business • Many organizations still struggle to optimize this powerful tool • Gartner - less than one-third of enterprises have a documented cloud strategy
- 27. TYPES OF CLOUD COMPUTING 27 Dr. NGPASC COIMBATORE | INDIA Cloud Computing Cloud Deployment Cloud Services IaaS PaaS SaaS Public Cloud Private Cloud Hybrid Cloud
- 29. DEPLOYMENT MODEL 29 Dr. NGPASC COIMBATORE | INDIA • Public Cloud are exposed to the public and can be used by anyone • Private Cloud used by single organization not exposed to the public • Hybrid Cloud distributed among public & private clouds Sensitive applications kept inside the organization’s network (private cloud) Other services can be hosted outside the organization’s network (public cloud) Users can them interchangeably use private as well as public cloud services in every day operations
- 31. PUBLIC Vs PRIVATE CLOUDS 31 Dr. NGPASC COIMBATORE | INDIA Terms Public Private Tenancy Multi-tenancy: The data of multiple organizations in stored in a shared environment Single tenancy: There’s only the data of a single organization stored in the cloud Exposed to the Public Yes: anyone can use the public cloud services No: only the organization itself can use the private cloud services Data Center Location Anywhere on the Internet - CSP services located Inside the organization’s n/w
- 32. PUBLIC Vs PRIVATE CLOUDS 32 Dr. NGPASC COIMBATORE | INDIA Terms Public Private Cloud Service Management The Cloud Service Provider (CSP) manages the services The organization must have their own administrators Hardware Components The CSP provides all the H/W & ensures it’s working at all times Organization has to buy physical servers to build the private cloud Expenses The CSP has to provide the h/w, set-up the application & provide the network accessibility according to the SLA (Service Legal Agreement) Can be quite expensive, since the h/w, applications & network have to be provided & managed by the organization itself
- 33. PUBLIC Vs PRIVATE CLOUDS 33 Dr. NGPASC COIMBATORE | INDIA Terms Public Private Others • Scalability is very high & reliability is moderate • Security matters & dependent on service provider • Performance - low to medium • It has shared servers. • Scalability is limited, and reliability is very high • It gives high class of security • Performance is high • It has dedicated servers Examples Amazon web service (AWS) and Google AppEngine etc. Microsoft KVM, HP, Red Hat & VMWare etc.
