海外TECH	DEV Community	NodeJS vs .NET	https://dev.to/code_jedi/nodejs-vs-net-4jo	NodeJS vs NETWhen it comes to deciding between two powerful web development technologies like Node js and NET it can be quite daunting Both are widely used for a multitude of web applications and each has its own advantages and drawbacks Node js created by Ryan Dahl in is a JavaScript runtime built on Chrome s V JID engine It offers an event driven architecture and a non blocking I O API which optimizes throughput and scalability in web applications where efficiency is an important consideration Node js also offers an extensive set of features and libraries making it a great choice for creating a wide range of applications One of the main benefits of Node js is its scalability and performance as it can quickly process requests without waiting for traditional page rendering Additionally developers can take full advantage of its asynchronous event based programming system which improves the flow of information On the other hand NET is a mature web development technology created by Microsoft in It provides full support for both client side and server side web development It also offers a wide set of libraries and features making it a great choice for creating large enterprise applications In terms of performance NET is not as fast as Node js as it takes a bit longer to process requests However thanks to its support for multi threading NET applications can still provide quick response times making them ideal for large scale projects Most importantly NET is the preferred choice for some organizations since they have extensive experience and expertise dealing with the Microsoft development environment When it comes to scalability both Node js and NET excel Although Node js has a slight edge in that respect NET performance is still good enough for most projects In the end both Node js and NET are great technologies for web development The choice really depends on your particular needs and requirements Node js is the natural choice for a project requiring speed and scalability whereas NET may be the right option for a project requiring more mature platform support Accelerate your software development learning with Educative	2023-06-07 18:48:20
海外TECH	DEV Community	Integrating Keycloak as my Identity Provider for IAM Identity Centre: Part one, deploying Keycloak on AWS	https://dev.to/aws/integrating-keycloak-as-my-identity-provider-for-iam-identity-centre-part-one-deploying-keycloak-on-aws-2ol1	Integrating Keycloak as my Identity Provider for IAM Identity Centre Part one deploying Keycloak on AWS It was the best of times it was the worst of times A Tale of Two CitiesIt started out innocently enough As part of working on a new blog post I needed a way to use an open source tool called samlaws that generates AWS short lived credentials that you can use to access your AWS resources This is a pretty common pattern and a good practice to do and for many organisations this means they integrate with their user directory sometimes this might be something like Active Directory or an LDAP server AWS IAM Identity Centre which is the new name for AWS Single Sign On allows you to integrate those identity providers into your AWS Account allowing your users to authenticate against that user directory and then get access to AWS resources So I needed to set up an Identity Provider IdP and decided to use an open source Identity and Access Management solution called Keycloak rather than the usual suspects of Active Directory or something like Auth What I thought would be a simple deployment ended up being less than straightforward This post outlines how you can get your own Keycloak IAM service up and running on AWS Why was it less than straightforward As it turns out that was down to some significant changes introduced in later versions of Keycloak that impacted how many tools created to simplify the deployment of Keycloak worked Or as I found did not In this post I will share how you can get both the older versions of Keycloak v as well as the latest versions I am running v up and running on AWS In a future post I will use the Keycloak service that this post helps you deploy and integrate this into AWS Identity Centre as our SSO Pre reqsAn AWS account to which you have the right level of access to configure a new Identity ProviderAn available VPC in the region you will be deploying KeycloakThe AWS cli I am using version aws cli Python Darwin exe x prompt off as well as AWS CDKv I am running build aa A domain that you have that allows you to create public certificates I have a domain called ricsue dev that is managed by Route Code resources used within the post located at keycloak awsI checked how much it cost to run this on my AWS bill for hours and it was less than £ Grabbing a public certificateA requirement of deploying Keycloak is to have a public certificate available You need to use Amazon Certificate Manager ACM to create a certificate You will use the Arn for this certificate in the provisioning tool Note A pre req here is that I had a domain name managed by Route This allowed me to easily register the certificates These are the steps I followed Within the ACM I created a new public certificate keycloak ricsue dev for a domain that I have setup previously to be managed by Route ricsue dev whilst I registered this via my preferred domain registrar I configured it to be managed by Route When creating the certificate within ACM the request contains a link that allows you to automatically create the Route verification entries so I used this to update the domain records This reduced the time to validate the certificateAfter about minutes ACM issued me my new certificate and I was able to extract the Certificate Arn running the following commandaws acm list certificates CertificateSummaryList CertificateArn arn aws acm eu west xxxxxxx certificate aecbac df b ae xxxxxx DomainName keycloak ricsue dev So with our certificate created we are now ready to go Part One Installing KeycloakThere are a number of ways you can deploy Keycloak into your AWS account I did not want to do this manually so I wanted to see what options I had when it came to automating the deployment I found a few options that were open to me based on which ever infrastructure as code tooling I preferred Using CDK via the cdk keycloak constructUsing CDK via the ecs keycloak constructUsing Terraform via a number of different third party modules such as terraform keycloak aws or ecs keycloakUsing CloudFormation via this deployment guide keycloak on awsExploring and trying these different options out made me realised something important and something that I think will save you a lot of time and frustration Many of the resources above help you deploy older versions of Keycloak and do not work for the latest versions So in this part of the blog I have split it out into two parts how you can install the older v versions of Keycloak and how you can install the later versions v on newer Which Version Now you might be wondering which version should I be using I think for most cases you will probably want to use the latest versions However there may be some use cases where you need to get an older version up and running so am including that in this post to be completely honest I did the work to review the different ways and rather than throw that all away to gt dev null I thought I would keep it as a timely reminder for why maintaining these tools and documentation is so important Keycloak version v or olderAs you can see from the list above I had a few options to get my Keycloa v server up and running After going through the documentation of each and looking at how much work effort was required for each and finally trying a few out I ended up settling for the CloudFormation solution You will find the template I used in the GitHub repo in the cf folder The file is called keycloak aurora serverless from new vpc template which is the template I used and is slightly modified from the origin repo of the resources I shared above You can see what it will deploy by checking out the documentation hereTo deploy the CloudFormation stack I needed to pass into the CloudFormation template the CertificateArn We are providing a stack name keycloak sso provider which you can change if you want and we then provide the certificate Arn via the parameter overrides aws cloudformation deploy template file keycloak aurora serverless from new vpc template stack name keycloak sso provider parameter overrides CertificateArn arn aws acm eu west xxxxxx certificate aecbac df b ae xxxxxxx capabilities CAPABILITY IAM tags keycloak demoThis will kick of the creation of your Keycloak environment configuring and then deploying all the AWS services needed you can track these in the CloudFormation console aws cloudformation deploy template file keycloak aurora serverless from new vpc template stack name keycloak sso provider parameter overrides CertificateArn arn aws acm eu west xxxxxx certificate aecbac df b ae xxxxxx capabilities CAPABILITY IAM tags keycloak demoWaiting for changeset to be created Waiting for stack create update to completeIt was simple and quick and within minutes I had my Keycloak environment up and running Successfully created updated stack keycloak sso providerBefore we access our Keycloak service however there are a couple of things we need to do The initial login credential for Keycloak the Admin user is stored in AWS Secrets Manager To grab the password we can use the following command to grab the Arn of the AWS Secret which contains that password and then use another command to display that password aws cloudformation describe stack resource stack name keycloak sso provider logical resource id KeyCloakKCSecretFEC query StackResourceDetail PhysicalResourceId arn aws secretsmanager eu west xxxxxxx secret KeyCloakKCSecretFEC ZISjZjDsmJ xxxxx Will display the arn which we can then use in the following command to grab the password in the below I have redacted it as XXXXX aws secretsmanager get secret value secret id arn aws secretsmanager eu west xxxxxxx secret KeyCloakKCSecretFEC ZISjZjDsmJ xxxxxx ARN arn aws secretsmanager eu west xxxxxxxxx secret KeyCloakKCSecretFEC ZISjZjDsmJ xxxxx Name KeyCloakKCSecretFEC ZISjZjDsmJ VersionId ccd fec ed d afdeabf SecretString password XXXXXXXXX username keycloak VersionStages AWSCURRENT CreatedDate T We now have our username keycloak and our password we now need to login to Keycloak The actual URL you need to use will to login to Keycloak is provided as an OUTPUT when CloudFormation completes We can access these values using the following command aws cloudformation describe stacks stack name keycloak sso provider query Stacks Outputs OutputKey OutputKey OutputValue OutputValue OutputKey KeyCloakKeyCloakContainerSerivceEndpointURLCEA OutputValue The value of OutputValue is the URL of an AWS Load Balancer that routes traffic to the Keycloak services running on Amazon ECS If we use this URL in a browser we will generate errors as the URL does not match the name of the ACM generated certificate which in this example was keycloak ricsue dev To fix the issue around mismatch of the certificate and the load balancer URL you need to create a CNAME record in your DNS to point to the Load Balancer URL This is what mine looks like in Route I can now use the address of to access my newly deployed Keycloak service logging in as the admin user keycloak using the password I obtained via AWS Secrets Manager The final part of my setup which is optional is to create a user that I will use to log in From the Admin screen it is easy to create a new user set a password under Credentials and then assign it to the admin role under Role Mapping I then logout of the Keycloak console and log back in with these new credentials to check it works and that I still have admin access Congrats you now have a Keycloak v server up and running If this is what you needed then great you are done Before leaving though check out the next section to see how to clean up remove resources created if you need to delete Keycloak from your AWS account Cleaning up and removing all resourcesIf you need to delete clean up your Keycloak v installation then you can do this using the following commandaws cloudformation delete stack stack name keycloak sso providerThe command will not generate any output and you will need to go to the AWS CloudFormation console to check progress of your resources being cleaned up When I ran this it took around minutes to complete Note When I used the original templates some resources the Aurora MySQL database had deletion protection enabled So if you do get an error when trying to clean up delete the stack make sure you check and remove the deletion protection and then try again Keycloak version vSo I kind of left the details of how to deploy older versions of Keycloak for reference in case anyone finds themselves needing to do that For most installations however you will most likely want to deploy newer newest versions of Keycloak This is where I ran into a spot of bother and spent three days trying to figure out how to do this The approaches outlined above just didn t work and I spent a lot of time trying to troubleshoot and find a solution In the end it was down to a bit of luck and the excellence of Alexander Widera that I got something working In the end what worked was using the CDKv construct with a bit of tweaking which I will go through now Again all the code is in the GitHub repo We still need the ACM certificate so that has not changed However what we need to do to get this working is create a customer Keycloak container image that provides some additional configuration values that are critical to getting Keycloak to work and provide some additional Java library files that Keycloak needs which are also missing Building our custom Keycloak container imageTo help you build your container image there is a script in the docker directory called build sh Review this script and UPDATE it replacing yourawsregion and replacewithyourawsaccount to reflect your AWS account details You can optionally change the name of the Elastic Container Registery that will be created and version number usr bin env bashAWS DEFAULT REGION yourawsregion AWS ACCOUNT replacewithyourawsaccount AWS ECR REPO keycloakCOMMIT HASH Once updated and BEFORE you run this script you need to download and copy into the providers folder a bunch of jar files There is a README file in the providers folder has helpful links Once you have downloaded the jar files into the providers folder it

but before we access it we need to use the info from the output to update the DNS record for the certificate you created We need to grab the URL from the load balancer which you should be able to easily see as it will be the only resource which has a URL reference In the above output this is the line keycloak demo KeyCloakKeyCloakContainerSerivceEndpointURLCEA You will need to create a CNAME record pointing to the ELB to the domain record This will allow you to access Keycloak via a simple link The final step is obtaining the admin username and password which the CDK construct configures AWS Secrets Manager to manage The admin username is keycloak and we can find out the password by running the following command passing in the value of the AWS Secret resource that was output by CDK In the above we can see this as arn aws secretsmanager eu west xxxxx️KeyCloakKCSecretFEC BmrYOayqQBmd xxxx your value will be different but similar looking aws secretsmanager get secret value secret id

browser enter your domain name and you should see the following screen Click on the admin link you should now be able to use the admin and password to log in Congratulations you now have a Keycloak service up and running Cleaning up and removing all resourcesIf you need to delete clean up your Keycloak installation then CDK makes that very easy to do However you will first need to remove the Deletion protection from your RDS database configuration before running this command If you do not the deletion process will fail aws rds describe db clusters query DBClusters DBClusterIdentifier DBClusterIdentifier output textkeycloak demo keycloakdatabasedbclusterece hzjlnplxzuiThe output will provide you with the Keycloak DB cluster resource which you can then use to disable deletion protection using the following command aws rds modify db cluster db cluster identifier keycloak demo keycloakdatabasedbclusterece hzjlnplxzui no deletion protectionYou can then run the cdk destroy command to remove your Keycloak resources cdk destroy keycloak demo Next stepsIn this post I shared how you can install the open source identity and access management project Keycloak in AWS We looked at how you can use the CDKv construct with a few tweaks to make it easier to deploy this project andYou are now ready for the next part of this post integrating Keycloak into AWS Identity Centre as
