 Exhibit 10.21 

APPDYNAMICS, INC. 

OUTSIDE DIRECTOR COMPENSATION POLICY 

AppDynamics, Inc. (the “Company”) believes that granting equity awards to members of its Board of Directors (the
“Board,” and members of the Board, the “Directors”) represents an effective tool to attract, retain, and reward Directors of the Company who are “independent” within the meaning of the corporate governance
rules of The NASDAQ Stock Market (the “Outside Directors”). This Outside Director Compensation Policy (the “Policy”) formalizes the Company’s policy regarding grants of equity awards to its Outside Directors.
Unless defined in this Policy, any capitalized term used in this Policy will have the meaning given to such term in the Company’s 2017 Equity Incentive Plan, as amended from time to time (the “2017 Plan”), or if the 2017
Plan is no longer in place, the meaning given to such term or any similar term in the equity plan then in place. 
 This Policy will be
effective as of the effective date of the registration statement in connection with the initial public offering of the Company’s securities (the “Effective Date”) with all annual equity grants to begin following the first
annual meeting of the Company’s stockholders (the “Annual Meeting”) following the Effective Date, unless otherwise determined by the Compensation Committee. 

 

	1.	NO CASH COMPENSATION OR PER-MEETING ATTENDANCE
FEES 

 There are (i) no cash compensation for service on the Board or committees of
the Board and (ii) no per-meeting attendance fees for attending meetings of the Board or committees of the Board. 
  

	2.	EQUITY COMPENSATION 

 Outside
Directors may receive any Awards (except Incentive Stock Options) permitted under the Company’s equity plans, including discretionary Awards not covered under this Policy. All grants of Awards to Outside Directors under this Section 1
will be automatic and nondiscretionary, except as provided in Section 5 below, and will be made in accordance with the following provisions and all other provisions of the equity plan under which it was granted (the “Plan”)
that are not inconsistent with this Policy: 
  

	 	a.	Initial Award. Each individual who first becomes an Outside Director following the Effective Date will be granted an award of restricted stock units (an “Initial Award”) covering a number of
Shares having a Value (as defined below) of $400,000, rounded down to the nearest whole Share. The Initial Award will be made on the date of the first Board or Compensation Committee meeting on or after the date on which such individual first
becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy. If an individual was a member of the Board and also an employee, becoming an Outside Director due to termination
of employment will not entitle the Outside Director to an Initial Award. 

 Each Initial Award will vest in 12 equal
installments with the first installment vesting on the first quarterly vesting date on or after the commencement of the applicable Outside Director’s service as an Outside Director and the remaining installments vesting each quarterly vesting
date thereafter, in each case subject to the Outside Director continuing to be a Service Provider through the applicable vesting date. Each Initial Award will fully vest immediately prior to a Change in Control, subject to the Outside Director
continuing to be a Service Provider. 

	 	b.	Annual Award(s). Subject to the terms of this Section 2.b., on the date of each Annual Meeting following the Effective Date, each Outside Director will be automatically granted award(s) of restricted stock units
(each, an “Annual Award”) covering a number of Shares having the applicable Value set forth below, rounded down to the nearest whole Share, for their service as an Outside Director, as the Outside Director who serves as the lead
director (if any) (the “Lead Director”), and/or as chair or member of a committee of the Board, as applicable. 

  

									
	 Board Service
  
	  	 	 	  	 	 
	 Outside Director
	  	$	230,000	  	  
	  
 Lead Director (in addition to
service as an Outside Director)
	  	$	20,000	  	  
			
	Committee Service	  	Chair	 	  	 Member

(other than Chair)
	 
			
	 Audit
	  	$	20,000	  	  	$	10,000	  
			
	 Compensation
	  	$	12,000	  	  	$	6,000	  
			
	 Nominating and Governance
	  	$	8,000	  	  	$	4,000	  

 Notwithstanding the foregoing, if as of the date of an Annual Meeting, an Outside Director has served as a
Director for less than six months, then the Value for each Annual Award such Outside Director is otherwise eligible to receive on such Annual Meeting will be 50% of the corresponding value set forth in the table above. 

Each Annual Award will vest as to one-fourth of such Annual Award on each of the first 4 quarterly
vesting dates following the grant date, with the 4th installment vesting on the date of the Annual Meeting following the grant date if prior to the
4th quarterly vesting date, in each case, subject to the Outside Director continuing to be a Service Provider through the applicable vesting date. Each Annual Award will fully vest immediately
prior to a Change in Control, subject to the Outside Director continuing to be a Service Provider. 
  

	 	c.	Value. For this Policy, “Value” means the average of the closing sales price for a Share (or the closing bid, if no sales were reported) as quoted on the primary stock exchange or national market
system in which the Common Stock is listed for the 30 trading days ending on and including the trading day prior to the grant date. 

  

	3.	BUSINESS EXPENSES 

 Each Outside
Director’s reasonable, customary, and documented expenses in connection with service on the Board or any committee of the Board will be reimbursed by the Company. 
  

	4.	TAXES 

 All payments under this Policy are intended
to be exempt from the requirements of Section 409A of the Internal Revenue Code and accordingly no payments will be made after the later of (a) the 15th day of the 3rd month following
the end of the Company’s fiscal year in which the expenses are incurred, or (b) the 15th day of the 3rd month following the end of the calendar year in which the expenses are incurred.
The Company will not reimburse an Outside Director for any taxes imposed or other costs incurred because of the receipt of any payments under this Policy. 

  
 2 

	5.	REVISIONS 

 The Board or any Committee designated by
the Board may amend, suspend or terminate this Policy at any time and for any reason. No amendment, suspension or termination of this Policy will materially impair the rights of an Outside Director regarding compensation already paid or awarded with
the consent of the affected Outside Director. Termination of this Policy will not affect the Board’s or the Compensation Committee’s ability to exercise the powers granted to it under a Plan regarding Awards granted under such Plan under
this Policy prior to such termination.

 4.1
Authorization. 
 (a) The Investor has all requisite power and authority to execute and deliver this Agreement, to purchase the
Shares hereunder and to carry out and perform its obligations under the terms of this Agreement. All action on the part of the Investor necessary for the authorization, execution, delivery and performance of this Agreement, and the performance of
all of the Investor’s obligations under this Agreement, has been taken or will be taken prior to the Closing.

 (b) This Agreement, when executed and delivered by the Investor, will constitute valid and
legally binding obligations of the Investor, enforceable in accordance with their terms except: (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of
creditors’ rights generally, and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies or by general principles of equity. 

(c) No consent, approval, authorization, order, filing, registration or qualification of or with any court, governmental authority or third
person is required to be obtained by the Investor in connection with the execution and delivery of this Agreement by the Investor or the performance of the Investor’s obligations hereunder. 

4.2 Investment Intent. The Investor is acquiring the Shares for investment for its own account, not as a nominee or agent, and not with
the view to, or for resale in connection with, any distribution thereof in violation of securities laws, and that the Investor has no present intention of selling, granting any participation in, or otherwise distributing the same. The Investor
further represents that it does not have any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer or grant participation to such person or entity or to any third person or entity with respect to any of the
Shares in violation of securities laws. 
 4.3 Purchase Entirely for Own Account. This Agreement is made with the Investor in
reliance upon the Investor’s representations to the Company, which by the Investor’s execution of this Agreement the Investor hereby confirms, that the Investor is purchasing the Shares for the Investor’s own benefit and account for
investment only and not with a view to, or for resale in connection with, a public offering or distribution thereof in violation of securities laws. 

4.4 Investment Experience. The Investor has substantial experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company and acknowledges that the Investor can protect its own interests. The Investor has such knowledge and experience in financial and business matters so that the Investor is capable of evaluating the
merits and risks of its investment in the Company. 
 4.5 Speculative Nature of Investment. The Investor understands and acknowledges
that the Company has a limited financial and operating history and that an investment in the Company is highly speculative and involves substantial risks. The Investor can bear the economic risk of the Investor’s investment and is able, without
impairing the Investor’s financial condition, to hold the Shares for an indefinite period of time and to suffer a complete loss of the Investor’s investment. 

4.6 Access to Data. The Investor has had an opportunity to ask questions of, and receive answers from, the officers of the Company
concerning this Agreement, as well as the Company’s business, management and financial affairs, which questions were answered to its satisfaction. The Investor believes that it has received all the information the Investor considers necessary
or appropriate for deciding whether to purchase the Shares. The Investor understands that such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the Company’s business and prospects, but
were not necessarily a thorough or exhaustive description. The Investor acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections included in such business plans or
otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results. The Investor

  
 -4- 

 
acknowledges that it is relying solely on its own counsel and not on the Company or its agents for legal advice with respect to this investment or the transactions contemplated by this Agreement.
Nothing in this Section 4, including the foregoing sentences in this Section 4.6, limits or modifies the representations and warranties of the Company in Section 3 of this Agreement or the right of the Purchasers to rely thereon. 

4.7 Accredited Investor. The Investor is an “accredited investor” within the meaning of Regulation D, Rule 501(a),
promulgated by the SEC under the Securities Act and shall submit to the Company such further assurances of such status as may be reasonably requested by the Company. 

4.8 Residency. The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of
business) is correctly set forth on Section 7.9 hereto. 
 4.9 Rule 144. The Investor acknowledges that the
Shares must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. The Investor is aware of the provisions of Rule 144 promulgated under the Securities Act which permit
resale of shares purchased in a private placement subject to the satisfaction of certain conditions, which may include, among other things, the availability of certain current public information about the Company; the resale occurring not less than
a specified period after a party has purchased and paid for the security to be sold; the number of shares being sold during any three-month period not exceeding specified limitations; the sale being effected through a “brokers’
transaction”, a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder); and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that notwithstanding any obligation under the Investors’ Rights Agreement, the Company may not be satisfying the
current public information requirement of Rule 144 at the time the Investor wishes to sell the Shares, and that, in such event, the Investor may be precluded from selling such securities under Rule 144, even if the other applicable
requirements of Rule 144 have been satisfied. The Investor acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for
any disposition of the Shares. The Investor understands that, although Rule 144 is not exclusive, the SEC has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered
offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so
at their own risk. 
 4.10 No Solicitation. At no time was the Investor presented with or solicited by any publicly issued or
circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares. 

4.11 “Bad Actor” Status. Neither the Investor nor any of its directors, executive officers, other
officers that may serve as a director or officer of any company in which it invests, general partners or managing members is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or
(iii) under the Securities Act and disclosed reasonably in advance of the Closing in writing in reasonable detail to the Company. 

4.12 No Brokers. The Investor has not engaged any brokers, finders or agents, and neither the Company nor any other Investor has, nor
will, incur, directly or indirectly, as a result of any action taken by the Investor, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement. 

4.13 Tax Advisors. The Investor has reviewed with its own tax advisors the U.S. federal, state, local and foreign tax consequences of
this investment and the transactions contemplated by this Agreement. With respect to such matters, the Investor relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. The
Investor understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

“security” (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the shares of Common Stock to the Investor in a manner that would require the registration under the Securities Act of the
