Summarized Problem
Tour House turned to Visionnaire for specialized Google Cloud Platform (GCP) support to evolve its proprietary application, as it did not have a dedicated in-house specialist for the platform. The need became urgent due to issues with Cloud Run, whose multiple IP addresses prevented integrations that required a fixed IP, and with MongoDB, which used external IP communication. Visionnaire was brought in to support the architecture review, resolve these bottlenecks, and provide a more secure infrastructure ready for the application's growth. 

Summarized Solution
Visionnaire provided specialized support for Tour House's infrastructure on Google Cloud Platform (GCP) through IT outsourcing and DevOps consulting, working with the existing environment. The solution included reviewing and optimizing VMs, Cloud Run, and MongoDB, as well as monitoring the infrastructure, using an agile methodology, Scrum, and squads. 

Results
With Visionnaire's consulting, Tour House was able to move already-developed features into production, primarily by resolving the Cloud Run issue involving multiple IP addresses and enabling an outbound IP suitable for integrations that relied on IP allowlisting. This was the most urgent issue because it was already directly affecting operations. 

Visionnaire's expertise also made MongoDB communication more secure, moving it away from an external public-IP connection and onto the private network within the GCP infrastructure. 

In addition, the existing infrastructure was reviewed and optimized, covering Cloud Run, virtual machines, multiple IP addresses, MongoDB connections, and overall VM monitoring, reducing technical risks and improving environment maintainability. 

Visionnaire also gave Tour House access to specialized GCP and DevOps expertise that the company did not have dedicated internally, enabling it to more safely assess the impact of application growth, new integrations, and the addition of microservices. 

As a result, future architecture and infrastructure issues were reduced, preventing the application from continuing to grow without specialized review and avoiding problems being discovered only after new components entered production. 

Technologies
Google Cloud Platform (GCP), Cloud Run, MongoDB, Python, React, Google Cloud Shell, Virtual Machines (VMs), VPC, VPN, public/private IP and fixed IP, APIs, buckets/cloud storage, Git, GitHub, GitLab, infrastructure as code/infrastructure scripts, deployment, DevOps, staging and production environments, Shell Script, Perl, Docker, and SQL databases.

Detailed Problem
Founded in 1990, Tour House is a Brazilian group specializing in corporate travel management solutions, leisure travel, events, incentive programs, and corporate experiences. The company combines technology, data, automation, and human service, giving organizations greater control, efficiency, and security in travel and expense management. 

Tour House turned to Visionnaire because it was developing its own application, already hosted on Google Cloud Platform (GCP), but did not have a dedicated in-house specialist for the platform. The company had an infrastructure/DevOps professional shared across other projects, capable of handling deployments and operational activities, but it needed more specialized support to assess the architecture, monitor the application's growth, and guide decisions related to the addition of new microservices and GCP infrastructure. The initial concern was preventive: to keep the system from growing with architectural issues that would only be discovered later, and to have a specialized partner for ad hoc consulting needs and, potentially, to take on part of the DevOps activities. 

This need became urgent when two concrete production issues emerged. The main one involved Cloud Run, which used multiple outbound IP addresses, while some integrations with internal and third-party systems required requests to originate from a previously authorized fixed IP. This limitation was preventing already-developed and tested features from being effectively used in production. The second issue involved MongoDB, which had been added to the architecture later and was communicating through an external IP; Tour House wanted to integrate it into the private network of its GCP infrastructure, adopting more secure internal communication aligned with best practices. 

Detailed Solution
Visionnaire's proposed solution was to provide IT professional outsourcing services to support Tour House's infrastructure on Google Cloud Platform (GCP), with a focus on consulting and specialized work on the existing environment. The work included reviewing and optimizing the cloud infrastructure, including virtual machines with multiple IP addresses, the Cloud Run configuration, the MongoDB machine and connections, as well as the overall monitoring, configuration, and optimization of VMs (virtual machines) on GCP. 

Visionnaire proposed carrying out these activities through an agile process based on Scrum, with sprints and iterative, incremental follow-up, using squad-based teams and cloud tools. The proposal also included technologies related to infrastructure administration, such as Shell Script, Perl, and Python, with the final technical details to be defined during the first few weeks, after gaining a deeper understanding of Tour House's environment. 

For the initial scenario, the solution was primarily sized around a Senior DevOps Support Analyst working on demand in a consulting model. 

In summary, the proposal was not to replace Tour House's entire infrastructure, but to provide specialized GCP and DevOps expertise to review, correct, optimize, and monitor the existing environment, giving the Tour House team the technical support needed to resolve the identified issues and sustain the application's evolution.
