Google in Microsoft Boundaries- Google Gear

Microsoft the ultimate and undisputed king of Desktop world is enjoying its dream spell for the past 10 years; on the other hand Google the "Innovator" is continuously releasing Internet centric software, based on fresh ideas and user demands such as Google Map, Google Desktop, Google Blogger, and lots of other Googlies. So far both empires have their boundaries defined and emperors were playing within it. Google Desktop search was the first attempt of Google penetration in Microsoft boundary which was not successful as it was countered by more powerful Microsoft Desktop search. Now Google is ready for a new attempt with its new weapon named as Google Gear! So what is Google Gear? A free, open-source multi-platform JavaScript application programming interface (API) that lets Web applications work offline. Below are the words from Google Representative

"With Google Gears, we're tackling a key limitation of the browser in order to make it a stronger platform for deploying all types of applications and enabling a better user experience in the cloud," said Eric Schmidt, CEO of Google, in a statement. "We believe strongly in the power of the community to stretch this new technology to the limits of what's possible and ultimately emerge with an open standard that benefits everyone."

Google hopes Gears will become the standard for adding offline capabilities such as data storage, application caching, and multithreading to online applications.

David Mitchell Smith, Gartner web analyst, said that "The idea of taking Web applications offline is big," he said. While Google Gears can be viewed as a competitive move against Microsoft, he said that's not the only valid frame of reference.

Google Gears is also a threat for rich Internet applications. "Rich clients become less compelling the more the Web applications continue to grow," said Smith from Google. "Ajax has certainly taken a bite out of the opportunities that RIA developers thought they had."

Following are three Key features of Google Gear;
  1. A local server, to cache and serve application resources (HTML, JavaScript, images, etc.) without needing to contact a server.
  2. A database, to store and access data from within the browser.
  3. A worker thread pool, to make web applications more responsive by performing expensive operations in the background

Google Gear is currently compatible with following set of browsers;

  • Apple Mac OS X (10.2 or higher) o Firefox 1.5 or higher
  • Linux o Firefox 1.5 or higher
  • Microsoft Windows (XP or higher) o Firefox 1.5 or higher o Internet Explorer 6 or higher

MOSS 2007 Guidelines for Performance optimization and Capacity Planning

MOSS 2007 has some limitations in terms of performance. These limitations and guidelines have to be followed in order to maximize MOSS performance and for avoiding any unpredictable behaviors or supportability issues.

Following are the details of performance guidelines along with their objects affected. This information will be handy for MOSS capacity planning and architecture design and also for checking product supportability.

The following table lists the recommended guidelines for site objects.

Site object

Guidelines for acceptable performance

Notes

Scope of impact when performance degrades

Site collection

50,000 per content database

Total farm throughput degrades as the number of site collections increases.

Farm

Site collection

150,000 per Web application

This limit is theoretical, and is dependent largely upon:

· Performance of the database server on which the configuration database resides.

· Performance of the Web servers in the farm.

· Network bandwidth between the Web servers and the database server.

This is not a hard limit, and assumes a single database server. Your environment may not be able to host this many site collections per Web application. Distributing content databases across additional database servers can increase the effective limit of the number of site collections per Web application. You should perform testing to determine the actual effective limit in your environment.

Farm

Web site

250,000 per site collection

You can create a very large total number of Web sites by nesting the subsites. For example, 100 sites, each with 1000 subsites, is 100,000 Web sites. The maximum recommended number of sites and subsites is 125 sites with 2,000 subsites each, for a total of 250,000 sites.

Site collection

Subsite

2,000 per Web site

The interface for enumerating subsites of a given Web site does not perform well as the number of subsites surpasses 2,000.

Site view

Document

5 million per library

You can create very large document libraries by nesting folders, using standard views and site hierarchy. This value may vary depending on how documents and folders are organized, and by the type and size of documents stored.

Library

Item

2,000 per view

Testing indicates a reduction in performance beyond two thousand items. Using indexing on a flat folder view can improve performance.

List view

Document file size

50MB (2GB max*)

File save performance is proportional to the size of the file. The default maximum is 50 MB. This maximum is enforced by the system, but you can change it to any value up to 2 GB.

Library, file save performance

List

2,000 per Web site

Testing indicates a reduction in list view performance beyond two thousand entries. For more information about large lists, see White paper: Working with large lists in Office SharePoint Server 2007 [ http://technet.microsoft.com/en-us/library/cc262813.aspx ] .

List view

Field type

256 per list

This is not a hard limit, but you might experience list view performance degradation as the number of field types in a list increases.

List view

Column

2,000 per document library

4,096 per list

This is not a hard limit, but you might experience library and list view performance degradation as the number of columns in a document library or list increases.

Library and list view

Web Part

50 per page

This figure is an estimate based on simple Web Parts. The complexity of the Web Parts dictates how many Web Parts can be used on a page before performance is affected.

Page

Managed path

20 per Web application

20 managed paths is a soft limit. Managed paths are cached on the Web server, and CPU resources are used to process incoming requests against the managed path list. You should test for performance before exceeding 20 managed paths in a single Web application.

Web application

The following table lists the recommended guidelines for people objects.

People object

Guidelines for acceptable performance

Notes

Users in groups

2 million per Web site

You can add millions of people to your Web site by using Microsoft Windows security groups to manage security instead of using individual users.

User profile

5 million per farm

This number represents the number of profiles which can be imported from a directory service, such as Active Directory, into the people profile store.

Security principal

Approximately 2,000 per ACL (Access Control List) on any securable object (scope)

The total size of the ACL on scopes can be no larger than 64kb. Because each security principal is approximately 32 bytes in size, there can be no more than approximately 2,000 security principals or less for each scope.  If this limit is reached, indexing of items in that scope, and all items below that scope, to fail.

Also, because SharePoint Groups are expanded during the indexing process, having more than 2,000 users or Directory Groups in a SharePoint group and using that group for securing scopes may cause indexing of items secured with these groups, and all items below them, to fail.

This limit only occurs when Windows Integrated Authentication is utilized.

The following table lists the recommended guidelines for search objects.

Search object

Guidelines for acceptable performance

Notes

Search indexes

One per SSP

Maximum of 20 per farm

Office SharePoint Server 2007 supports one content index per SSP. Given that we recommend a maximum of 20 SSPs per farm, a maximum of 20 content indexes is supported.

Note that an SSP can be associated with only one index server and one content index. However, an index server can be associated with multiple SSPs and have a content index for each SSP.

Indexed documents

50,000,000 per content index

Office SharePoint Server 2007 supports 50 million documents per index server. This could be divided up into multiple content indexes based on the number of SSPs associated with an index server.

Content sources

500 per SSP*

This is a hard limit enforced by the system.

Start Addresses

500 per content source*

This is a hard limit enforced by the system.

Alerts

1,000,000 per SSP

This is the tested limit.

Scopes

200 per site

This is a recommended limit per site. We recommend a maximum of 100 scope rules per scope.

Display groups

25 per site

These are used for a grouped display of scopes through the user interface.

Crawl rules

10,000 per SSP

We recommend a maximum 10,000 crawl rules irrespective of type.

Keywords

15,000 per site

We recommend a maximum of 10 Best Bets and five synonyms per keyword.

Crawled properties

500,000 per SSP

These are properties that are discovered during a crawl.

Managed properties

100,000 per SSP

These are properties used by the search system in queries. Crawled properties are mapped to managed properties. We recommend a maximum of 100 mappings per managed property.

Authoritative pages

200 per relevance level

This is the maximum number of sites in each of the four relevance levels.

Results removal

100

This is the maximum recommended number of URLs that should be removed from the system in one operation.

Crawl logs

50,000,000

Number of individual log entries in the crawl log.

The following table lists the recommended guidelines for logical architecture objects.

Logical architecture object

Guidelines for acceptable performance

Notes

Shared Services Provider (SSP)

3 per farm (20 per farm maximum)

 

Zone

5* per farm

The number of zones defined for a farm is hard coded to 5.

Web application

99 per SSP

This limit includes the number of Web applications on child farms consuming resources on this SSP.

Internet Information Services (IIS) application pool

8 per Web server

Maximum number is determined by hardware capabilities.

Site collection

50,000 per Web application

 

Content database

100 per Web application

 

Site collection

50,000 per database

 

The following table lists the recommended guidelines for physical objects.

Physical object

Guidelines for acceptable performance

Notes

Index servers

1 per SSP*

 

Application servers running Excel Calculation Services

No limit

 

Query servers

No limit

Because 100 content databases are supported for each query server, the number of query servers required per farm is based on the number of content databases in the farm. For example, if there are 500 content databases in your farm, you will need at least 5 query servers.

Web server/database server ratio

8 Web servers per database server

The scale out factor is dependent upon the mix of operations.

Web server/domain controller ratio

3 Web servers per domain controller

Depending on how much authentication traffic is generated, your environment may support a greater number of Web servers per domain controller.

Microsoft SoftGrid Application Virtualization

Microsoft SoftGrid virtualization is a virtualization solution designed for making applications available just like electricity. This concept changes applications into network services that no longer need to be installed. User can access their application by simply clicking application icon on their desktop and they will get their application from soft grid virtual application servers. I am comparing this solution with Citrix Access suite. Citrix solution provides web experience for all applications. This solution is providing windows application experience to the end-user and as well as web experience by using terminal services. The beauty of this solution is that application will run locally but in a protected mode thanks to the system guard which restricts OS from altering application dlls and other system files. Any existing application can convert in to SoftGrid enabled application by passing it through sequencer, a program records application interaction with OS and make it compatible for system guard. Application running through softgrid will use application code and DLL on demand. DLLs will be provided by virtual application server as soon as they needed. For further details, check out this site http://www.softricity.com/products/index.asp
