Complex Application DevOps Integration and Installation Automation
Our client is an independent software vendor making the transition from SaaS-only to providing on-premise and private cloud installations. It had been offering software only in a multi-tenant cloud service, but found that its customers in regulated industries required secure, on-premise, or virtual private cloud installations. Prior to our engagement, the need to install components of the software across a minimum of five servers, each configured with dozens of packages, caused delays in implementing Proofs-of-Concepts, disrupted the sales process, and created an ongoing support burden for both the support team and their end-user organizations.
OpStack performed an analysis of the situation, designed, and then constructed an extensible automation platform for our ISV client that:
Installs the client’s software in on-premise, or virtual private
- Runs interactively or unattended.
- Prompts users for any missing configuration elements.
- Performs validation of prerequisites.
Leverages a major open source orchestration tool to:
- Install or upgrade the operating system, supporting packages, and application components as needed for each server in the customers environment.
- Fully configures DNS, SSH, firewalls, and VPNs to support the application.
- Distributes SSH keys across the configuration.
- Allows for site-specific selection of repositories for standard packages.
- Supports installation on multiple Linux distributions and all major cloud providers.
- Centralizes all site-specific options to a single configuration file.
- Logs all steps and, on any error, allows for correction and restart from that or any earlier checkpoint in the process.
- The solution works in both Internet-accessible and air-gapped environments.
- Extends our client’s CI/CD stack to include versioning and packaging of tagged releases.
- Reduction of average install-time from one week to under an hour.
- The installed application topology for systems built in the cloud, on-prem with Internet connectivity, and on-prem and without access to external repositories is now identical — simplifying product documentation and standardizing support procedures.
- Business impact is both faster time-to-revenue for new clients and lower support costs for the installed base.
