  java gets faster and faster as it learns realworld usage to optimize the compiled code. This is why the idea that Java is slower than even C is just BS. for a complex system, no compile time can really know the best optimization to use. This is where java's on the fly in time compilation shines. Because at run time it gets the code paths that is most used and has the best view of where to optimize. Yes, it takes some cycles for java to optimize it completely. But if you have a long running program, there is simply nothing better than java. Neither for speed nor for how quickly you can build the system. Rest of the languages are only good to cover either system level programming or for short run cycle programs. If you are running a batch application that uses 100% cpu for 10 secs and shuts down then java won't have the time to optimize, in those case just use graalvm and compile java to native code directly.

  You had created the eks cluster in the past what is that we can expect in this new series? How is it different from the previous EKS cluster you have created?

• 
  @AntonPutra11 сағат бұрын

  There have been few new developments on EKS side. 1. Kubernetes auth configmap is deprecated and recommended approach is to use new EKS API to add new users to the cluster 2. New way to grant permissions to application (we no longer use IAM OIDC provider and IAM roles for service accounts, instead we use Pod identities) 3. Some other small features in certain controllers like aws load balancer controller etc

  In this video you create all resources using direct terraform resources. But we also have publicly available modules from Anton Babenko to create EKS and simplify the terraform layer, in my opinion. What do you think is better to use in production cases? Is it worth using such public terraform modules or is it better to create all the resources yourself?

• 
  @AntonPutra3 күн бұрын

  I respect him, i just generally don't like using open source modules. For example that open source module still uses auth configmap to manage users. It's very easy for them to start using API but it will break your infra and you would have to keep using old versions until you create new eks clusters (just from my personal experience) Modules are great for consulting and temporary envs, when you don't need to maintain clusters for over the year. I know a lot of copy pasting but when you have 20+ clusters, update module can in all envs can take months or even year :)

  Thanks for the video could you explain in layman terms what exactly is the oidc provider and its role in eks does it act like a authentication broker between iam and k8s in aws?

• 
  @AntonPutra3 күн бұрын

  oidc provider allows you to establish relationship between AWS IAM and Kubernetes RBAC. 1. you create IAM role and define trust relationship with Kubernetes service account 2. you create Kubernetes service account and LINK IAM role with Kubernetes service account Finally you can assign IAM permissions to Kubernetes pods. BUT you no longer need it at all, new better way is pod identities, video comparing all approaches coming in few days

  @@rafalkita884 thanks, it heavily depends on the Kubernetes version itself not EKS. For example K8s can deprecated some APIs for example old ingress beta v1 and you would need to upgrade all your yaml files. So it's very hard to come up with general recommendation.

Customers and orders tables are linked by the foreign key customers->id ~ orders->customer_id Orders table and payments table has the foreign key orders->id ~ payments->order_id Now how would you shard this database? You can't use a single shard key, because both customer_id and order_id are important that ensure all the related rows are in a single shard. So how would you solve this problem?
