After creating your AWS account,watch for an email from AWS containing your credit code. To redeem the code, sign intoyour AWS console, click your name at the top of the screen, clickBilling & CostManagement, and then clickCredits. Enter the code and any additional information, andthen clickRedeem.As shown in Table 1-2, AWS Educate offers many appealing benefits. If your institutionis an AWS Educate member, you receive more AWS credits. If you don’t have a creditcard, you can use the AWS Educate Starter Account (ESA). However, your usage ofAWS services is limited to the annual AWS credit amount. Once those credits run outeach year, you can’t use the account any longer until your AWS anniversary date whenyou can apply for a renewal.If you can use a credit card to sign up for a regular AWS account, you’ll receive moreAWS credits, and you’ll have access to the AWS free tier services.

15Microsoft Azure also offers free accounts, and some options provide special benefits forstudents and educators. To use Azure, you create a Microsoft account and then create oneor more subscriptions within the account. If your school uses Office 365, youmightalready be able to authenticate to Azure using your existing Microsoft account. The threetypes of Azure subscriptions (there are others) most relevant tothis courseareas follows:Free trial subscription.This subscription is available to the public and requires acredit card. The credit expires after 30 days while the free trial services last for 12months.Azure for Students subscription.This subscription is available to full-time facultyand students (olderthanage 18) in a STEM-related field at an accredited, degree-granting educational institution. Use a school-issued email account. You might alsobe able to generate an Azure for Students verification code through your school’sMicrosoft Azure Dev Tools for Teaching platform.Azure for Students Starter subscription.This subscription is available only tostudents (olderthanage 13) from accredited educational institutions. Use a school-issued email account. This subscription does not provide sufficient access to servicesto complete the projects in this course unless you upgrade to a “pay-as-you-go”subscription, which requires a credit card.For choosing a subscription type, consider the details shown in Table 1-3.Table 1-3Azure free subscription optionsSubscriptionOptionBenefits toStudentsPaymentOptionsNotesFree Trial$200 Azure credit for upto 30 daysRequirescredit cardand phonenumberMust upgrade to a “pay-as-you-go” subscription* after 30 days
