海外TECH	DEV Community	10 Tips for Those Who Decide to Start a New Project on AWS	https://dev.to/roman_abdulmanov/10-tips-if-you-decide-to-start-a-project-on-aws-3ebd	Tips for Those Who Decide to Start a New Project on AWSHere I collected few tips that may be useful for those just at the beginning of their AWS journey Account separationIt is worth separating production and dev accounts from the very beginning It costs almost nothing but if you do not do it initially you will have to spend precious time on rework This is important to do for the following reasons It allows you to limit people accessing the production environmentIt allows you to create a loosely coupled architecture where the prod environment doesn t depend on the testing environmentYou will have separate billing so that you will have the ability to see how much you pay for your production This is necessary for passing different security and compliance checks PermissionsThe question may quickly arise how to limit the permissions for developers For example Protect against admins assuming roles between accounts Developers with administrator rights could assume a role from another account by defaultIf you have not restricted access to SSM decrypt methods etc developers can access various secrets stored in the environment tokens keys etc Access to the Billing DashboardThe simple solution grant only the necessary permissions but this is more complex than it looks because the scope of rights changes constantly and needs to be continuously reviewed With this approach developers will periodically lose access when they need to develop something new that was not considered earlier To solve this you can grant a more comprehensive range of rights e g up to an Administrator on a test account But set different permission boundaries Good post about it I also recommend setting up MFA for all accounts to reduce the risk of token leaks AutomationAWS is very captivating with its simplicity in setting something up manually especially at the beginning of a project But behind this simplicity lies many complexities There is a very high probability of breaking something by accidentIt is difficult to repeat the environment and for example create an identical staging for the developerIt isn t easy to understand how our system looks like in general because this knowledge is in our headsTo solve this I suggest using one of the popular solutions TerraformPulumiServerless FrameworkAWS SAMAWS CloudFormation CloudFormationThe solutions above use CF So if using CF to manage infrastructure you should familiarize yourself with its limitations The most frustrating thing is the resource limit which you will run out of very quickly if you prefer a serverless approach or have a large project So to avoid this problem at a crucial moment I suggest you think about a strategy for placing resources in nested stacks e g plugin for Serverless Framework CognitoAWS Cognito is a powerful service for a customer identity and access management But when setting it up you can make two mistakes that can cause serious trouble in production Case sensitive user pool If you create a User Pool programmatically you must set the CaseSensitive parameter to false otherwise it will default to true This complicates the sign in process e g User test co vs user test co And most importantly after creating the User Pool you can no longer change this settingThe same applies to Mutable attributes This means that if for example you mark an email as Mutable users will not be able to change their emails and most importantly you cannot change the value of Mutable without recreating the User PoolRecreating the User Pool is only possible by resetting user passwords which would look suspicious Therefore if you made such mistakes when configuring your User Pool and have already launched the product you may have unexpected problems that could have been easily avoided initially DynamoDBDynamoDB unlike the usual relational databases recommends using the single table design For Node js users to make this approach easier to understand and make the code incredibly simpler I recommend looking at the OneTable library Here are some benefits Single table designTypeScript supportLocal unit test supportSimple APIMigrations supportIndexes amp conditions supportBuilt in encryption support BackupsAWS has a built in backup service This is a very powerful service that for example allows you to create a particular type of backup without the possibility of deleting previously created snapshots But this service has its limitations We are faced with the fact that when restoring DynamoDB we must manually restore DDB Streams This would be problematic if as we do everything is deployed through CloudFormation which does not like manual changes Therefore to avoid surprises at the most inconvenient moment in addition to creating backups you need to develop test and document the recovery procedure and periodically perform test recovery to ensure that the process is still up to date LambdaIf you are using lambda you probably have heard about the cold start problem To solve this there are different workarounds warm up requests language specific solutions lambda provisioned concurrency etc But I want to focus on one in my opinion the most critical factor in addition to the chosen language amp memory function bundle size Your bundle size directly affects the cold start time because AWS needs to prepare the code before it can be run Even if you use Lambda Layers and extract dependencies these Layers still need to be loaded So I advise trying to minimize the bundle size in every possible way For example we use Node js we never add AWS SDK because it is already present in the environment we use esbuild because it showed the best results in terms of speed and size and as a result we don t have a single function larger than KBs AlarmsThe alarm system is incredibly useful for detecting suspicious activity and important alerts For example we set up alarms when various errors occur in the system Lambda errors amp throttlingErrors in logs e g from docker WAF alarmsBilling alarms spending more than a certain amount in Custom metricsAnd then we connected SNS to send these alarms to us in a special slack channel Audit logsYou can enable activity logging via CloudTrail It costs almost nothing but can be indispensable when analyzing suspicious activity or determining why something is not working in the system We had an incident with user registration in Cognito and this logging helped to sort out the real reasons	2023-03-01 08:18:37
