Leverage Identity

• Integrate with your existing IDM system

• Configure in the portal

- Users

- Roles

- Privileges

• Incorporate in your apps

Identity matters!

Project Prioritization

Approach to Solutions

• Configure first

• Customize second

- Extend where possible

Deviations from “core” increase risk!

Rapid & Agile

• Keep iterations brief (~30 days)

• Involve stakeholders

• Stop | restart at any time

• Iterations terminate with the business need

Each iteration results in deliverable you can use…

Environment Isolation

• Production: operational, real-time

compute environment

• Staging: a separate, mirrored, pre-

production environment

• Development: a limited scale and scope

environment sufficient for the

development of primary code and data

modeling.

High Availability

What is acceptable downtime for your operational business workflows?

Availability (%) Downtime per

year

Downtime per

week

95.0 18.25 days 8.4 hours

99.0 3.65 days 1.68 hours

99.9 8.76 hours 10.1 minutes

99.99 52.56 minutes 1.01 minutes

99.999 5.26 minutes 6.05 seconds

Workload Separation

• Separate technology deployments by solution pattern

• Benefits include:

- Reduced risk

- Improved service delivery

- Reduced system resource contention

- Optimized resource utilization

Typically SLAs determine which server

deployments need to be separated

Deployment ArchitectureThree Big Decisions

1. Which deployment pattern?

2. Where will it run?

3. Who will run it?

Deployment ArchitectureReference Methodology

A Two-Pass Approach

1. Conceptual Level

- Focus on business objectives & technology strategy

- Understand broad organizational characteristics

- Use qualitative & quantitative evaluation methods

- Output – deployment strategy & best fit patterns

2. Implementation Level

- Focus on technical specifics, in key areas (e.g. security)

- Evaluate best fit patterns in detail, identify potential issues/risks

- Begin logical architecture design

- Output – specific deployment architecture w/ associated considerations/risks

Deployment ArchitectureConceptual Level Considerations

Characteristics Preference(s)

IT Maturity Low, Moderate, Advanced

Cloud Policy / Preference Cloud First, Ok w/ Cloud, Cloud Averse

Infrastructure Elasticity Easy, Moderately Easy, or Hard to Provision Infrastructure

Data Sensitivity (security) Very Sensitive (e.g. HIPPA), Business Sensitive, Somewhat, Not Sensitive

GIS Workflows (next 2-3 years) Web Mapping, Cartographic Mapping, 3D, Analysis, Real-time, Big Data

Public / Constituent Engagement Heavy, Some, None

Level of Collaboration / Sharing External and Internal, Internal Only, Limited, None

Use of 3rd Party Services Prefer, Ok, None

Comfort Outsourcing to Esri Very, Some, Limited, Note

Service Level Agreement None, 95%, 99% +

Disaster Recovery Strategy None, Future, Imminent

Deployment ArchitectureImplementation Level Considerations

Area Focus

Security Authentication & User Store Preferences (e.g. AD domains/forests, web adaptor)

Authorization Requirements (e.g. granularity, enterprise groups)

ArcGIS Server Federation?

Infrastructure Virtual or Physical (including desktop)

Operating System Preferences

Load Balancers, Reverse Proxies, and Forward Proxies

Availability & Resiliency High Availability Requirements

Disaster Recovery and/or Backup and Restore Requirements

Distribution Distributed GIS Design

Network Topology (bandwidth & latency)

Geodata Replication/Synchronization Requirements

Deployment ArchitectureLooking to the Future

Desktop GIS (standalone GIS)

Server GIS(client-server GIS)

Web GIS(cloud GIS)

Distributed Web GIS
