So, While You’re Digesting...• Why Talk About Cloud? – Corporate IT Challenges
• What is Cloud Computing? • Why is the cloud appealing? • Are there issues? • Is GIS cloud-appropriate? • Sign me up?
5www.skeinc.com
Corporate IT Challenges1. Complexity
– Security, Architecture, Policy, Procedures, Servers, Data Centres, SANs, FW, Networks, Disaster Recovery, ...
2. Cost– Hundreds thousands to millions of $ to implement
business solutions– Require on-going maintenance and support– Specialized technologies and skills
3. Dealing with the Unreasonable Demands of the GIS Department.
Result => Huge $ and Effort Commitment
And then there was cloud....

What is Cloud Computing• The provision of software, hardware
and networking solutions as a service over the web.
8www.skeinc.com
What Makes it Appealing? • Scalable – right-size resources based on demand• Agile – deploy quickly• Accessible – web based (any time, anywhere)• Low Technical Risk - No installation required, no
servers, no specialized software, no additional staff, automatic updates,...– Technology someone else's responsibility/headache– Ability to leverage proven solutions based on industry best
practices.
• Overhead – less: staff, computers, energy, space..• Affordable – based on use / accounts.
– Economies of scale, because there are typically multiple different clients on the same infrastructure.

How Does it Work?
10www.skeinc.com
Cloud Service Models
• Software as a Service (SaaS)– End user app’s delivered as a service– Examples: • Google Apps, • Social media, • Virtual Desktops, • Salesforce.com
11www.skeinc.com
Cloud Service Models
• Platform as a Service (PaaS)– Combination of SaaS and IaaS purposed
for development and deployment – Examples: Development and Testing
Tools, Database Management Systems, Directory Services.
12www.skeinc.com
Cloud Service Models
• Infrastructure as a Service (IaaS)– Computing resources: Virtual
Machines, VLAN’s, Virtual Storage, etc.
– Examples: Virtualized Computers, Storage Systems, Networking
13www.skeinc.com
Cloud Deployment• Private Clouds
– Specific to an organization (usually internally hosted)
• Public Clouds– Available to anyone (Internet based)
• Community Clouds– Shared resources for a community/industry
• Hybrid Clouds– A mix of the above
14www.skeinc.com
Cloud Issues• Security
– Where is your data?, who can see it?– How reliable/trustworthy is the provider?– Where is the provider and what are their IT practices?
• Physical premises • System security• SW upgrades and patching• SLA’s
• Responsibility is shared...
15www.skeinc.com
Cloud Issues
• Security controls by service type...
• Disaster recovery• Absence of industry standards• Integration with existing systems• Dependant on Internet access speed and reliability.• Often less functionality than desktop.
16www.skeinc.com
Amazon Outage• Amazon cloud went down in April, 2011
– Many high profile sites went down: Foursquare, Reddit, Quora, Hootsuite…
• Lessons Learned:– Plan for failure– Retain expertise to develop and implement Disaster
Recovery Plan– Security and disaster recovery is a joint responsibility– Create internal back-up options
• Can you get your data if your service provider goes down
– Distribute your risk across different sites/providers– Know your service provider and what they will/will not
do• SLA’s matter
17www.skeinc.com
Go Daddy Outage• Go Daddy web sites and DNS servers go down
went down in September 2012. – A DNS (Domain Name Server)
is like a telephone exchange for the Internet. Directs traffic to appropriate site.
– Thousands of sites affected.
• We host our own cloud service in a secure facility, but we use the Go Daddy DNS.
• So, even though our services remained up and running just fine, for several hours, no one could “find” them.
• #$*@**@&^^@@!!
18www.skeinc.com
Lessons Learned• Clients demand more from
service providers.
• Even the best laid plans...
• OWASP (IT security standards), isn’t necessarily the standard.
• Cloud is in constant change. (and, that doesn’t change.)

Cloud Standards
20www.skeinc.com
Cloud Adoption
• Public Sector: Slow, primarily becauseof security concerns– Non-sensitive data storage– Public web sites– Development and testing environments– Data disaster recovery sites– US Govt ahead of Canadian Govt
• Private Sector: High adoption rate– Social media Sites: Facebook, Twitter, ...– Google, MS, Amazon, SalesForce...
21www.skeinc.com
Municipal Cloud• Rationalize IT infrastructure. • More easily enable growth and change. • Less dependency on internal expertise; e.g. security,
IT hardware, network administration. • Increased options for remote access and the
portable office. • Increase GIS deployment options.

Cloud Companies
23www.skeinc.com
Cloud GIS / Spatial Cloud Computing (SC2)
• Software as a Service: Highly suitable for basic to intermediate GIS functionality.– E.g. www.giscloud.com
• Platform as a Service: Highly suitable for basic to intermediate GIS functionality. – E.g. Google Aps; ArcGIS Online
• Infrastructure as a Service: High potential for replacing internal high-end GIS infrastructure.– E.g. Infrastructure Ontario.
24www.skeinc.com
SC2 Introduces DaaS• New key component of cloud computing.• Spatial data essential to any GIS – and most
organizations don’t have it. • Also, significant money saving potential:
– According to ESRI 2012 almost 90% of data used by petroleum sector companies comes from external source.
– Massive potential if data provided as a service rather than handled locally.
– 100s of data sources– Interoperability still an issue.

Compare Cloud GIS vs. Traditional Enterprise GIS
• Functionality (specific vs. general)• Infrastructure (lease vs. own)• Time and ease• Spatial content• Security• Business continuity• Client support• Cost
www.skeinc.com
SKE’s SC2 - GeoPortal• A hosted, cloud computing solution that uses
geography to integrate business information. • A common geo-base for an organization’s
information and data with Google maps and imagery.– maps; tabular data; and, documents / unstructured
content
• Clients subscribe… nothing to buy.• Secure and reliable: Audit approved. • Standards-based and integrates with dozens of
technologies, such as…
www.skeinc.com
Benefits of Ontario GeoPortal• Data: Spatial data and info. services provided.• Technology: Always available (HA). Scalable. SLA
guaranteed. • Applications: Comes with full suite of applications.
Enables business info. system integration.• Simple: Easy to learn and implement. No GIS specialty
required. • Cost Effective: Reduces our client’s IT operating costs
by app. 25%/annum ($250,000).Subscription costs well defined. • Subscription model: $1/day/user (1600 named users)• Resource utilization model: App. $2000/month

How We Handle Security
a. Distributed Model – your data stay behind your firewall.
b. Data hosted in Toronto – which is important for some Canadian clients.
c. Security Model– Uses Windows Authentication– TRA-tested to meet rigid standards– Users only see the information to which they have been
granted access.
d. Multiple redundancy ensures your solution is always available.
Distributed Model

Important Considerations
• Cloud implementation is:– optimal for collaboration – optimal for GIS implementation (eliminates
complexity, cost, skill requirements).
• Build / design for leverage. One-off projects are expensive; leveraged technology is much cheaper and easier to maintain.
• Geography brings new capacity for information access, sharing, and understanding.
