amazon free signal server

Installation

• Needs git, docker, docker-compose
• Checkout the submodules git submodule update --init && git submodule update
• Apply patch to the source code cd Signal-Sever && git apply ../patches/patch1 ** The patch disables recapctha, APN and replaces the depency of amazon IAM to a local server version

build docker

• Build the docker image docker-compose build

Setup

Setup the abuse database

• docker-compose up -d postgresql-abuse
• docker-compose exec -u postgres postgresql-abuse psql -c 'create database abusedb;'

Amazon EC2

Dynamic configurations are coming from an ec2 instance

Amazon Elastic Compute Cloud (EC2) is a part of Amazon.com's cloud-computing platform, Amazon Web Services (AWS), that allows users to rent virtual computers on which to run their own computer applications. EC2 encourages scalable deployment of applications by providing a web service through which a user can boot an Amazon Machine Image (AMI) to configure a virtual machine, which Amazon calls an "instance", containing any software desired. A user can create, launch, and terminate server-instances as needed, paying by the second for active servers – hence the term "elastic". EC2 provides users with control over the geographical location of instances that allows for latency optimization and high levels of redundancy.[2] In November 2010, Amazon switched its own retail website platform to EC2 and AWS.

AmazonAppConfig

AWS AppConfig helps simplify the following tasks: Configure Source your configurations from Amazon Simple Storage Service (Amazon S3), AWS AppConfig hosted configurations, Parameter Store, Systems Manager Document Store. Use AWS CodePipeline integration to source your configurations from Bitbucket Pipelines, GitHub, and AWS CodeCommit.

Validate
While deploying application configurations, a simple typo could cause an unexpected outage. Prevent errors in production systems using AWS AppConfig validators. AWS AppConfig validators provide a syntactic check using a JSON schema or a semantic check using an AWS Lambda function to ensure that your configurations deploy as intended. Configuration deployments only proceed when the configuration data is valid.

Deploy and monitor
Define deployment criteria and rate controls to determine how your targets retrieve the new configuration. Use AWS AppConfig deployment strategies to set deployment velocity, deployment time, and bake time. Monitor each deployment to proactively catch any errors using AWS AppConfig integration with Amazon CloudWatch. If AWS AppConfig encounters an error, the system rolls back the deployment to minimize impact on your application users.
