Setup for first time a Coldcard Wallet in a secure way
A hardware wallet is a type of cryptocurrency wallet where you can store your private keys in a secure physical device. They have major advantages over standard software wallets: private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext.
I love to use Terraform for creating and managing infrastructure on the cloud. However, there are cases in which I prefer Serverless Framework for creating and deploying resources on AWS, those involve services such as Lambda function and API Gateway. Besides the process can be also automated using Gitlab CICD. I believe Terraform plus Serverless Framework is a perfect combination for Infrastructure as Code and Function as a Service on Amazon Web Services.
A serverless architecture is a way to build and run applications and services without having to manage infrastructure. On AWS we can create Lambda, API Gateway, DynamoDB and other resources that are “Serverless”. Some tools can help us to create and deploy our Lambda functions and other infrastructure resources such Serverless Framework, SAM, Terraform, Cloudformation and others.
The Certified Kubernetes Application Developer or CKAD is a challenging exam. Performance-based test that requires solving multiple issues from a command line. I studied and passed the 3 Kubernetes Certifications (CKA/CKAD/CKS), and I want to share valuable information to prepare and pass this exam.
The Certified Kubernetes Application Developer or CKAD is a hands-on test and consists of a set of performance-based items (19 problems) to be solved in a command line and is expected to take approximately two (2) hours to complete.
