2 Cloud Computing We will be discussing: Where is the Cloud? What does the Cloud look like? Types of cloud computing. IaaS Infrastructure as a Service PaaS Platform as a Service SaaS Software as a Service The evolution of computing from Eniac to The Cloud. Cloud computing benefits / challenges. Questions?

4 What is it like in the Cloud?

5 What is it like in the Cloud?

6 Hopefully not this!

7 Types of Cloud Services Infrastructure as a Service (Iaas) Platform as a Service (Paas) Software as a service (Saas)

8 Infrastructure as a Service: Storage Internet

9 Cloud Storage Advantages o Easy to Use o Sharing of data o Available all the time o Cost effective o Scalable o Secure o Device independent o Does not require a wired connection

10 Cloud Storage Disadvantages o Privacy o No guarantee of continued service o No additional backup o Charges in the future - ransom o Bandwidth needed to access large data o No control over data

11 Cloud Storage Examples o Apple icloud o Google Mail o Dropbox o Carbonite Backup o Wikipedia o Netflix

12 Platform as a Service: Example - Company X wants to migrate from maintaining it s own Microsoft Exchange Server to cloud based with it s users running Outlook. Current traditional on premises hosting. Cloud solution.

13 Traditional Solution Requirements: o Office space o Servers o Cooling o Security concerns o Team of experts o Operating systems, software, upgrades o Firewalls, Intrusion prevention systems o Failover / Disaster recovery o Uninterrupted Power Supply

14 Traditional Solution Disadvantages o Time consumption o Space utilization o Higher costs (upfront and continuing) o Slow scaling o Obsolescence o Qualified personnel

15 Cloud Solution 1. Login 2. Customize Option1 Option2 Option3 Option4 3. Start using the application

16 Cloud solution Disadvantages: Almost None

17 Platform as a Service o Google Mail o Go Daddy Web hosting o Amazon Web Services o Google App Engine o VMWare

18 Software as a Service Example Company X is an architecture firm which has recently obtained a large building remodel project. It needs to run the latest version of AutoCAD on 7 workstations for 4 months. Traditional on premises hosting. Cloud solution.

19 Traditional Solution Requirements: o 7 new computers o Purchase software o Local support needed o Centralized storage array o Backup systems o Firewalls, Intrusion prevention systems o Office space No remote access o Delays in obtaining products / software

20 Traditional Solution Disadvantages o Time consuming o Higher costs o Does not scale well o Obsolescence o Qualified support personnel o Disposition of equipment

21 Software as a Service Advantages: o Easy to Use o Available all the time o Cost effective o Scalable computing power can vary o No lead time for hardware or software o Does not require local expertise

22 Software as a Service Disadvantages: o None Examples: o Google Apps for Business o Salesforce o Microsoft Office 365

23 Separation of Responsibilities

24 Types of Clouds

25 Timeline Main-Frames Personal-computers Internet 1940 s 1950 s 1960 s 1970 s 1980 s 1990 s 2000 s ENIAC, 1 st general purpose computer Mini-Computers / Clusters Local Networks Cloud

26 Evolution (or is it?) Mainframes (1960 s): Massive computers at a distant location which ran programs, allowed multiple users access, and kept data. Required relatively low performing terminals to access. Cloud Computing (2000 s): Massive computers at distant locations which run programs, allow multiple users access, and keep data. Require relatively low performing computers to access.

27 Cloud Computing Benefits o Highly optimized virtual data centers. o Software, Hardware available for use when needed: pay per use basis. o Instant scale up / scale down. o Fast to get started, costs less o Multi-tenancy

28 Cloud Computing Challenges o Security / Privacy o Regulatory compliance - None o Efficient migration of applications from enterprise datacenters to the cloud o A lack of interoperability and consistency between different cloud providers
