Goals of the Project

  • Easily manageable and predictable infrastructure

  • Security enhancement
The initial request was to help with AWS servers management, their optimization, and improving the uptime. After the high-level tasks decomposition, we concentrated on two main goals: building an easily manageable and predictable infrastructure, security enhancement.
The Podcast Host Ltd. has its servers and databases on AWS. To reach better manageability, predictability, and security our team developed a solution that included several steps that are listed below.
CI/CD Pipeline Implementation
To make the development and testing processes easier and more predictable we installed and configured Jenkins and test jobs for a development server.
Monitoring and Logging Setup
To ensure proactiveness in troubleshooting we set up Zabbix that is proactively warning the client about the emerging issues. Also, we implemented performance metrics, processes, and servers availability.

Using ELK Stack we configured log collection service and aggregated logs from servers to one centralized storage. It allowed us to simplify the process of sorting and searching for logs in the storage.
Security Enhancement
For reliable remote access with automatic failover, we configured a VPN server using Pritunl.
Configuration Management
As a part of implementing best DevOps practices with Infrastructure as a Code approach, we used Terraform to create all AWS resources and Ansible for configuration. This allowed the client to have a reliable infrastructure configuration store with an audit of changes and an ability to replicate any part on a moment notice.

Also, we configured a discovery service for new EC2 instances and started instances via AutoScaling Group.
