Google learns to crawl Flash Now

kinds, from Flash menus, buttons and banners, to self-contained Flash websites. Recently, we’ve improved the performance of this Flash indexing algorithm by integrating Adobe’s Flash Player technology.

In the past, web designers faced challenges if they chose to develop a site in Flash because the content they included was not indexable by search engines. They needed to make extra effort to ensure that their content was also presented in another way that search engines could find.

Now that we’ve launched our Flash indexing algorithm, web designers can expect improved visibility of their published Flash content, and you can expect to see better search results and snippets. There’s more info on the Webmaster Central blog about the Searchable SWF integration.

• “First impressions count: make sure the ad unit with the highest CTR is the first ad unit in the HTML code of your page. Keep in mind that the first ad unit in the source code is not always the first ad unit that your users will see when the page finishes loading in their browser.”
  [Inside AdSense: First impressions count]

So the wider ad formats are doing better than the other ones and the reason is that they actually take up fewer lines. And so with every additional line, you have a chance of losing that interested user.
• So the wider formats do best so specifically, the top three formats are the 336×280 that you see on the page; the 300×250 medium rectangle; and then the 160×600 wide skyscraper.

Square and rectangle ads placed within the center column also do well, provided they are placed in context to the content. Ads placed below the fold tend to perform least well, although that isn’t a hard-and-fast rule.”

Google processes over 20 petabytes of data per day

Google currently processes over 20 petabytes of data per day through an average of 100,000 MapReduce jobs spread across its massive computing clusters. The average MapReduce job ran across approximately 400 machines in September 2007, crunching approximately 11,000 machine years in a single month. These are just some of the facts about the search giant’s computational processing infrastructure revealed in an ACM paper by Google Fellows Jeffrey Dean and Sanjay Ghemawat.

Twenty petabytes (20,000 terabytes) per day is a tremendous amount of data processing and a key contributor to Google’s continued market dominance. Competing search storage and processing systems at Microsoft (Dyrad) and Yahoo! (Hadoop) are still playing catch-up to Google’s suite of GFS, MapReduce, and BigTable.

	Aug. 2004	Mar. 2006	Sep. 2007	Number of jobs (1000s)	29	171	2,217

map	395	1,958	4,083
reduce	269	1,208	2,418

Google processes its data on a standard machine cluster node consisting two 2 GHz Intel Xeon processors with Hyper-Threading enabled, 4 GB of memory, two 160 GB IDE hard drives and a gigabit Ethernet link. This type of machine costs approximately $2400 each through providers such as Penguin Computing or Dell or approximately $900 a month through a managed hosting provider such as Verio (for startup comparisons).

The average MapReduce job runs across a $1 million hardware cluster, not including bandwidth fees, datacenter costs, or staffing.

Summary

The January 2008 MapReduce paper provides new insights into Google’s hardware and software crunching processing tens of petabytes of data per day. Google converted its search indexing systems to the MapReduce system in 2003, and currently processes over 20 terabytes of raw web data. It’s some fascinating large-scale processing data that makes your head spin and appreciate the years of distributed computing fine-tuning applied to today’s large problems.
