In today\'s world, security is a primary concern for any company that wants to migrate its operations to the Internet, especially when using new services such as Amazon Web Services (AWS). AWS offers a robust and scalable infrastructure, but setting up a VPS (Virtual Private Server) with advanced security measures requires knowledge and attention to details. Next, we will explore how to configure a VPS on AWS, implement a web application and guarantee its protection against possible threats. It is crucial to consider not only the power and flexibility that AWS offers, but also the security implications of data migration and applications for a new one. Setting up a VPS on AWS: The basic structure on AWS to set up a VPS consists of starting an EC2 (Elastic Compute Cloud) instance. This is the main service that allows users to start and manage virtual servers. Firstly, you need to:

  • Access your AWS account and navigate to the EC2 panel.
  • Select \\\\\\\"Start Instância\\\\\\\" to start the configuration process.
  • Escolher uma Appropriate Amazon Machine Image (AMI), which can be pre-configured by AWS or customized for your specific needs.

After selecting the base image, it is important to choose the appropriate instance type based on your processing and storage requirements. Consider the balance between cost and performance to avoid unnecessary waste of resources.

Network and Security

A network configuration and the application of security rules are fundamental. You must clearly define access by creating security groups that act as virtual firewalls to control traffic from/for your instance:

  • Security Groups: Make sure you configure rules to allow traffic only from endereços IP confiáveis. This minimizes the risk of unauthorized access.
  • NAT Gateways: Use NAT gateways to allow your instance to access the Internet without being exported directly, adding an extra layer of protection.

Web Application Implementation

The next step is to configure your VPS and implement your web application. A popular approach to using Docker due to its flexibility and efficiency: Install Docker on your EC2 instance to easily orchestrate containers that encapsulate all the components needed for your web application. Create custom Docker images that contain your web application along with all its necessary dependencies. This method guarantees the consistency of the production development environment, reducing conflicts and common errors associated with different environments. Website Maintenance Keep your website updated and safe and vital. Use tools like Jenkins or GitLab\'s CI/CD pipelines to automate deployments and continuous testing. Also, consider services like Mox, which can offer customized web maintenance solutions. Protecting your environment: The importance of cryptography and other security measures cannot be underestimated. Always use HTTPS with appropriate SSL/TLS certificates to protect data transmitted between the client and the server. Consider integrating VPNs, advanced cryptography, or tools like AWS CloudTrail to monitor suspicious activities and implement detailed logging.
