SMPP

 SMPP (Short Message Peer-to-Peer) is a protocol used for exchanging short message data between entities, such as SMS (Short Message Service) service centers and external applications. It is commonly used by businesses and organizations to send and receive SMS messages and other short messages, such as alerts and notifications.


SMPP is based on a client-server model, in which a client (such as an SMS service center or an external application) sends and receives messages through an SMPP server. The client and server communicate with each other using a series of commands and responses that follow a specific format.


When a client wants to send an SMS message using SMPP, the following process occurs:


The client connects to the SMPP server using a network connection, such as TCP/IP.

The client sends a message to the server indicating the sender and recipient of the SMS message, as well as the content of the message.

The server checks that the recipient's phone number is valid and, if it is, sends a message indicating that the SMS message has been accepted.

The server delivers the SMS message to the recipient's mobile phone.

SMPP is a widely used protocol for exchanging short message data, and it is particularly useful for businesses and organizations that need to send and receive large volumes of SMS messages or other short messages. It is flexible and scalable, and it is supported by many SMS

Testing crossplane on Digital ocean

  Crossplane brings the management of external resources into kubernetes through kubernetes APIs. This can in some situations be an alternative to other IaC such as terraform.  In the example below, we will create a droplet on DO by applying a kubernetes manifest using kubectl. The exemple suppose the kubernetes cluster in which crossplane will be installed is already up. ```bash kubectl create namespace crossplane-system helm repo add crossplane-stable https://charts.crossplane.io/stable helm repo update # install crossplane helm install crossplane --namespace crossplane-system crossplane-stable/crossplane # install the upjet digital ocean provider cat << EOF | kubectl apply -f - apiVersion: pkg.crossplane.io/v1 kind: Provider metadata: name: provider-upjet-digitalocean spec: package: crossplane-contrib/provider-upjet-digitalocean:v0.3.0 EOF # create the upjet digital ocean provider secret kubectl apply -f - << EOF apiVersion: v1 kind: S...

It is a powerful tool that allows developers to collaborate on projects and manage the source code of their projects. Some common Git commands include: git init: This command is used to initialize a new Git repository. It creates a new directory and sets up the necessary configuration files and directories. git clone: This command is used to create a local copy of a remote repository. It allows a developer to download a copy of the repository and all its history to their local machine. git add: This command is used to add new or modified files to the staging area. The staging area is a temporary holding area where changes are stored before they are committed to the repository. git commit: This command is used to save changes to the repository. It creates a new snapshot of the project and adds it to the repository's history. git push: This command is used to send changes from the local repo...
