Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial information has been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet data as of December 31, 2014 was derived from audited financial statements, but does not include all disclosures required by GAAP. The condensed consolidated financial information should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 27, 2015.
	In the opinion of management, the accompanying unaudited condensed consolidated financial information includes all normal recurring adjustments necessary for a fair statement of the Company's financial position, results of operations, comprehensive loss and cash flows for the interim periods, but is not necessarily indicative of the results that may be expected for the year ending December 31, 2015. All intercompany accounts and transactions have been eliminated in consolidation.
	Reclassification
	In the condensed consolidated statement of cash flows, certain prior year amounts have been reclassified to conform to the current year presentation. There was no change to the net cash flows from operating, investing, or financing activities as a result of the reclassification.
	Public Offering
	In March 2014, we closed a follow-on public offering, in which we sold 4,000,000 shares of our Class A common stock at a price to the public of $89.25 per share. The aggregate offering price for shares sold in the offering was approximately $344.1 million, net of underwriters' discounts and commissions, and offering expenses.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include depreciable lives for property and equipment, stock-based compensation, income taxes, accrued liabilities, and collectability of accounts receivable. Actual results could differ from those estimates.
	Risks and Uncertainties
	Inherent in our business are various risks and uncertainties, including our limited history operating our business at its current scale and development of advanced technologies in a rapidly changing industry. These risks include our ability to manage our rapid growth and our ability to attract new customers and expand sales to existing customers, as well as other risks and uncertainties. In the event that we do not successfully implement our business plan, certain assets may not be recoverable, certain liabilities may not be paid and investments in our capital stock may not be recoverable. Our success depends upon the acceptance of our technology, development of sales and distribution channels, and our ability to generate significant revenues from the use of our technology.
	Segments
	We follow the authoritative literature that established annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products and services, geographic regions and major customers.
	We operate our business as one operating segment. Our chief operating decision makers are our Chief Executive Officer and Chief Financial Officer, who review financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
	Concentrations of Risk
	Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We extend credit to customers based upon an evaluation of the customer’s financial condition and generally collateral is not required. As of March 31, 2015 and December 31, 2014, no individual customer accounted for 10% or more of total accounts receivable. For the three months ended March 31, 2015 and 2014, no individual customer represented 10% or more of our total revenues.
	Recent Accounting Pronouncements
	In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards ("IFRS"), the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 related to revenue recognition. The new guidance sets forth a new five-step revenue recognition model that replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 provides retrospective or modified prospective methods of initial adoption and is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is not permitted. In April 2015, the FASB proposed a one year deferral of the effective date of this new standard. This proposed revision to the standard is not yet effective. We are currently evaluating the method of adoption and the impact that this standard will have on our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15 related to status as a going concern. The new guidance explicitly requires that management assess an entity's ability to continue as a going concern and may require additional detailed disclosures. ASU 2014-15 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Though permitted, we do not plan to early adopt. We do not believe that this standard will have a significant impact on our consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-05 related to a customer's accounting for fees paid in a cloud computing arrangement. The new guidance requires that management evaluate each cloud computing arrangement in order to determine whether it includes a software license that must be accounted for separately from hosted services. ASU 2015-05 applies the same guidance cloud service providers use to make this determination and also eliminates the existing requirement for customers to account for software licenses they acquire by analogizing to the guidance on leases. ASU 2015-05 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 and provides the option of applying the guidance prospectively to all arrangements entered into or materially modified after the effective date or on a retrospective basis. Early adoption is permitted. We are still evaluating the impact this standard will have on our consolidated financial statements.

	Our certificate of incorporation, as amended and restated, authorizes us to issue 75,000,000 shares of Class B common stock, $0.0001 par value per share, and 750,000,000 shares of Class A common stock, $0.0001 par value per share. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each holder of Class B common stock is entitled to ten votes per share and each holder of Class A common stock is entitled to one vote per share. Shares of Class B common stock may be converted into Class A common stock at any time at the option of the stockholder, and are automatically converted upon sale or transfer to Class A common stock, subject to certain limited exceptions. At its discretion, the board of directors may declare dividends on shares of common stock, subject to the rights of our preferred stockholders, if any. Upon liquidation or dissolution, holders of common stock will receive distributions only after preferred stock preferences have been satisfied.
	Preferred Stock
	Our certificate of incorporation, as amended and restated, authorizes us to issue 10,000,000 shares of preferred stock at $0.0001 par value per share. Our board of directors has the authority to provide for the issuance of all the shares in one or more series. At its discretion, our board of directors may designate the voting rights and preferences of the preferred stock.

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation
	Our 2004 Equity Incentive Plan (the “2004 Plan”) authorizes the granting of options to purchase shares of our Class B common stock, restricted stock units ("RSUs") and other stock-based awards to our employees, consultants, officers and directors. Our 2013 Equity Incentive Plan (the “2013 Plan” and, together with the 2004 Plan, the “Plans”), which was a successor to our 2004 Plan, authorizes the granting of options to purchase shares of our Class A common stock, RSUs and other stock-based awards to our employees, consultants, officers and directors.
	Options granted under the Plans may be incentive or nonstatutory stock options. Incentive stock options may only be granted to employees. The term of each option is stated in the award agreement, but shall be no more than ten years from the date of grant. Options typically vest over a period of four years.
	A summary of the option activity under the Plans during the three months ended March 31, 2015 is presented below:
		Options Outstanding

	Exercisable at March 31, 2015	4,460,131		$	7.03	6.24	$	381,286
	RSUs entitle the holder to receive shares of Class A common stock as the award vests. RSUs typically vest over a period of four years. The fair value of an RSU is determined by using the closing price of our Class A common stock as reported on the New York Stock Exchange on the date of grant. The Company's non-vested RSUs do not have nonforfeitable rights to dividends or dividend equivalents.
	A summary of the RSU activity under the 2013 Plan during the three months ended March 31, 2015 is presented below:
		Number of Shares Underlying Outstanding RSUs		Weighted-Average Grant-Date Fair Value per RSU
	Non-Vested outstanding at December 31, 2014	2,818,661		$	77.77
	RSUs granted	1,599,278		99.9
	RSUs vested	(210,353	)	91.66
	RSUs forfeited	(40,020	)	80.81
	Non-Vested outstanding at March 31, 2015	4,167,566		$	85.53
	Stock-based compensation expense is amortized on the straight-line method over the requisite service period. As of March 31, 2015, total unrecognized compensation expense, adjusted for estimated forfeitures, related to stock options and non-vested RSUs was approximately $326.2 million which is expected to be recognized over a period of 3.4 years.
	The summary of shares available for issuance for equity based awards (including stock options and RSUs) during the three months ended March 31, 2015 is as follows:

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	Our provision for income tax expense (benefit) for interim periods is determined using an estimate of our annual effective tax rate and adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment.
	Our effective tax rate is impacted by and differs from the federal statutory rate primarily due to non-deductible stock-based compensation and the adverse effect of losses incurred in certain foreign jurisdictions for which we do not realize a tax benefit. Our effective tax rate may also be adversely impacted by the amount of our income before income tax expense (benefit) relative to our income tax expense, non-deductible expenses and changes in tax law such as the expiration of the U.S. federal research and development credit at the end of 2014.
	Our effective tax rate was 16.4% and (167.9)% for the three months ended March 31, 2015 and 2014, respectively. The difference in the effective tax rates for the three month periods is attributable to the change in the relationship between non-deductible items including stock-based compensation, and meals and entertainment, and the loss before income tax expense (benefit). The impact of adjustments to our effective tax rate for discrete items and non-deductible expenses is greater when our loss before income tax expense (benefit) is lower.
	During the three months ended March 31, 2015, we recognized an income tax benefit of $2.0 million, which includes $1.0 million of discrete tax benefits relating to disqualifying dispositions on incentive stock options. During the three months ended March 31, 2014, we recognized an income tax expense of $3.5 million, which included $0.8 million of discrete tax benefits relating to disqualifying dispositions on incentive stock options.
	We are currently under examination by the Internal Revenue Service ("IRS") for taxable years 2012 and 2013, which may lead to proposed adjustments to our taxes or net operating losses with respect to the years under examination as well as in subsequent periods that utilize these net operating losses. To date, we have not received any notices of proposed adjustments from the IRS related to this or any other examination periods.

	Total	$	135,803
	We are subject to certain routine legal proceedings, as well as demands and claims that arise in the normal course of our business. We make a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed and adjusted to reflect the impacts of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter.
	We are not aware of any pending legal proceedings that we believe, individually or in the aggregate, would be expected to have a material adverse effect on our business, operating results, or financial condition. We may in the future be party to litigation arising in the ordinary course of business, including claims that we allegedly infringe upon third party intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and management resources.

Fair Value Measurements	Fair Value Measurements
	We categorize assets and liabilities recorded at fair value based upon the level of judgment associated with inputs used to measure their fair value. The levels of the fair value hierarchy are as follows:
	•	Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
	•	Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
	•	Level 3—Inputs are unobservable inputs based on our own assumptions and valuation techniques used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.
	Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.
	The following table presents the fair value of our financial assets using the fair value hierarchy:

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying unaudited condensed consolidated financial information has been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet data as of December 31, 2014 was derived from audited financial statements, but does not include all disclosures required by GAAP. The condensed consolidated financial information should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 27, 2015.
	In the opinion of management, the accompanying unaudited condensed consolidated financial information includes all normal recurring adjustments necessary for a fair statement of the Company's financial position, results of operations, comprehensive loss and cash flows for the interim periods, but is not necessarily indicative of the results that may be expected for the year ending December 31, 2015. All intercompany accounts and transactions have been eliminated in consolidation.
Reclassification	Reclassification
	In the condensed consolidated statement of cash flows, certain prior year amounts have been reclassified to conform to the current year presentation. There was no change to the net cash flows from operating, investing, or financing activities as a result of the reclassification.
Pubic Offering	Public Offering
	In March 2014, we closed a follow-on public offering, in which we sold 4,000,000 shares of our Class A common stock at a price to the public of $89.25 per share. The aggregate offering price for shares sold in the offering was approximately $344.1 million, net of underwriters' discounts and commissions, and offering expenses.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include depreciable lives for property and equipment, stock-based compensation, income taxes, accrued liabilities, and collectability of accounts receivable. Actual results could differ from those estimates.
Risk And Uncertainties	Risks and Uncertainties
	Inherent in our business are various risks and uncertainties, including our limited history operating our business at its current scale and development of advanced technologies in a rapidly changing industry. These risks include our ability to manage our rapid growth and our ability to attract new customers and expand sales to existing customers, as well as other risks and uncertainties. In the event that we do not successfully implement our business plan, certain assets may not be recoverable, certain liabilities may not be paid and investments in our capital stock may not be recoverable. Our success depends upon the acceptance of our technology, development of sales and distribution channels, and our ability to generate significant revenues from the use of our technology.
Segments	Segments
	We follow the authoritative literature that established annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products and services, geographic regions and major customers.
	We operate our business as one operating segment. Our chief operating decision makers are our Chief Executive Officer and Chief Financial Officer, who review financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
Concentrations of Credit Risk	Concentrations of Risk
	Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We extend credit to customers based upon an evaluation of the customer’s financial condition and generally collateral is not required. As of March 31, 2015 and December 31, 2014, no individual customer accounted for 10% or more of total accounts receivable. For the three months ended March 31, 2015 and 2014, no individual customer represented 10% or more of our total revenues.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards ("IFRS"), the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 related to revenue recognition. The new guidance sets forth a new five-step revenue recognition model that replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 provides retrospective or modified prospective methods of initial adoption and is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is not permitted. In April 2015, the FASB proposed a one year deferral of the effective date of this new standard. This proposed revision to the standard is not yet effective. We are currently evaluating the method of adoption and the impact that this standard will have on our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15 related to status as a going concern. The new guidance explicitly requires that management assess an entity's ability to continue as a going concern and may require additional detailed disclosures. ASU 2014-15 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Though permitted, we do not plan to early adopt. We do not believe that this standard will have a significant impact on our consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-05 related to a customer's accounting for fees paid in a cloud computing arrangement. The new guidance requires that management evaluate each cloud computing arrangement in order to determine whether it includes a software license that must be accounted for separately from hosted services. ASU 2015-05 applies the same guidance cloud service providers use to make this determination and also eliminates the existing requirement for customers to account for software licenses they acquire by analogizing to the guidance on leases. ASU 2015-05 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 and provides the option of applying the guidance prospectively to all arrangements entered into or materially modified after the effective date or on a retrospective basis. Early adoption is permitted. We are still evaluating the impact this standard will have on our consolidated financial statements.
