SANDBOX SOLUTIONS

Outline

• Challenges• What are Sandbox Solutions?• How do they work?• What can I do them Sandbox Solutions?• How can they be managed?

Challenges• Dev, Admin Fight!

• Change production farm to Full • Memory Leaks• Update web.config files• Bad code that eats up farm resources• Deploy everything to the GAC

• Admins have some control using CAS• Difficult to implement• Difficult to get right

• Largest cause of SharePoint Support cases

Overview of the Sandbox

• Allows a subset of the full capabilities in the SharePoint API

• Secure – enforcing the sandbox• Execute in a partially trusted environment• Code executes in a special service process• Subject to CAS• Validation framework• Provides way to do custom farm wide validation for the deployed packages

• Each solution is isolated to its site collection

Types of Sandboxed Solutions Sandboxed Solutions Support

• Sandboxed solutions offer developers a subset of the SharePoint API available fully trusted solutions• Site collection and

site scoped Features• Many XML constructs available: Modules, Lists,

ContentTypes, etc.

• Client technologies to access external data – JavaScript, Silverlight etc.

• Offloading resource usage and access handling to client

SANDBOX RESOURCE MONITORING

Load Balancing

• Sandboxed solutions can be run in two modes• Local Mode• Execute code on the SharePoint WFE• Low administration overhead• Lower scalability

• Remote Mode• Execution on back-end farm machine• Via dedicated service applications

• Load balanced distribution of code execution requests

Sandbox Solution MonitoringHow it works• Site collection quotas specify the warning and hard limits for

number of resources that can be used per day• Sum of resource measures are taken across solutions

deployed to site collection• I.e., add up CPU Points for all solutions

• Max of resource utilization measures checked against site collection quota to determine if it should be throttled/blocked

Monitored ResourcesMetric Name Description Units Resources Per

You can tweak these values to fit your need…

Sandbox Solution MonitoringCase Study

• A solution has executed 40 SQL queries (via the SharePoint OM)

• One point for SQL is 400 queries• Means for SQL it’s consumed .1 resource points • So the resource usage is for the day for that solution is .1

resource points + other counters

Sorting Uniform Order FormDemo

Key Takeaways

• You can build complex forms using InfoPath (Rapid Application Development)

• Consider Sandbox Solutions first• Safe• Monitored• Allow more manageable hosting scenarios

• Quotas are for all sandbox solutions in the site collection• Be creative with your solution design (Use Silverlight + WCF)• InfoPath + Sandboxed Solution Better Together
