What is ArcGIS Enterprise

What’s Included with ArcGIS Enterprise

• ArcGIS Server – the core web services component for making maps and performing

analysis

• Portal for ArcGIS – allows you to share maps, applications, and other geographic

information with other people in your organization

- Identity Management

• ArcGIS Data Store – lets you configure data storage for hosting and federated servers

used with your deployment

- ArcGIS Managed PostgreSQL Database

• ArcGIS Web Adaptor – allows you to integrate your ArcGIS Server and Portal for ArcGIS

with your existing web server and your organization’s security mechanisms

- Windows – IIS and Java

- Linux – Java

Site Design ConsiderationMulti-node, high number of services

• Ensure Required Infrastructure Resources

- Network Stability

- NAS Stability for ArcGIS Server and Portal config stores

- RAM

- CPU

• Try to Avoid during Working Hours

- Publishing High Number of Services

- Adding/Removing Nodes

• Distribute Recycle Times

Site Management Consideration

• Identify unused services and reduce min (to 0 if possible)

• Tune slow services

• Provide best practices to the publishers

• Monitor resources

- RAM and committed memory

- CPU

- Network latency

Hosting Server

• Scalable Solution

- Publish thousands of services

Tuning Definitions

• Performance – Speed, in other words, response time (seconds)

• Scalability – Ability to increase output and maintain acceptable performance

• Capacity – maps per second (users x maps per second)

• Bottleneck – Something that limits performance and capacity

Tuning Methodology

• Profile each tier starting at the top

Tuning Methodology – Case Study 1Profile each tier starting at the top

• You can use tools like fiddler to narrow down the problem URL

Tuning Methodology – Case Study 1

• Look at statistics of problem service

Tuning Methodology – Case Study 1

• If ArcMap MXD, use MXDPerfStat, shows call to DB is slow

• If ArcGIS Pro, PerfTools is available – search for “ArcGIS Pro Perftools” in a search engine

Tuning Methodology – Case Study 1https://oracle-base.com/articles/misc/sql-trace-10046-trcsess-and-tkprof#trace_example

• Run query using Oracle Trace for example

Tuning Methodology – Case Study 2

• In this case the number of feature vertices was the problem

• Compare to FGDB performance

System Design

System DesignProvide Sufficient Hardware Resources

• GIS Systems are bound by

- CPU

- Memory – when there are a large number of services

- Disk – Image service, synchronization (Collector causes lots of I/O)

- Network – low bandwidth deployment

- Poorly configured virtualization

- Can result in 30% higher performance degradation

System Monitor

Monitoring Enterprise GISChallenges

• Multiple Administrators

• Multiple disparate monitoring/diagnostic tools

• Data collected in reactive fashion, not proactive – on demand and for a limited time

• Correlation of data with different timestamp is difficult

• ArcGIS Administrators do not have access to all tools, data, and reports

• Challenging to quickly identify the root cause and take appropriate measures

MotivationGrowing Complexity of ArcGIS Enterprise

• Certificates

• Load Balancer

• Firewall

• ArcGIS Web Adaptor

• Portal for ArcGIS

• Storage

• ArcGIS Server

• ArcGIS Data Store

• Databases

ArcGIS Monitor

• Search for “ArcGIS Monitor”
