ZOOM GROUP is a family business that was born in 1976 with the sole objective of connecting Venezuela with the world through package and document messaging. That is why, and based on this goal, in just one year they manage to establish the first office in Miami to expand their portfolio to one of the strongest markets with the largest number of shipments in the world. From that moment and within the corporate strategy, different lines of business have been consolidated, such as BUZOOM virtual sections in 1984, MEGAZOOM subscription agency for international magazines in 1991, ZOOM exchange house in 2001, among many others, which has allowed to have a dynamic and large-scale business at the regional level. Now, Grupo Zoom, being one of the business leaders at the regional level in the Courier and low-value transaction sector, wants to maintain this strength that, based on technology, has allowed it to endure since its inception and continue to grow to provide better service to its customers – he assures Carlos Atencio Vice President of the company.

Within the Digital Transformation that the company is seeking to face the new challenges that the market is imposing, Grupo Zoom aims to modernize its current Datacenter infrastructure that allows it to be more agile in the implementation and adoption of new processes, taking its Know How that positioned them as leaders in the region. To achieve this, they see that public cloud technology is the option that best suits their needs.

Within this process there are great challenges that must be taken into account in order to implement the solution successfully, first of all, the legacy systems that the company has represent one of the most critical processes since it is the Core of the business, and so that For a successful migration, its components must be updated so that they can be implemented in the new operating systems, so within this challenge, it is imperative to use tools that migrate as transparently as possible, with the knowledge of experts who define the scope of the platforms. cloud. Another challenge is the databases that must have superior performance, since being a low-value network, 3 million records per day of financial operations such as remittances and payments are stored, finally the interconnectivity that the company has must meet high standards. levels of stability and reliability as it connects around 10 business partners including Western Union.

Within the solution, two deployment zones are defined in GCP, in one the DMZ is implemented and in the other, a private network, so that the communication towards the servers in the DMZ is made directly through the Google Gateway, this allows to make use of the qualities of this Google component without the need to implement highly available Firewall appliances. For communications with external partners, a highly available VPN concentrator-type PFSense Appliance is implemented, which is the entry point to the private zone. In the same way, the private zone will have access by RFC 1918 to the Compute Engine instances where the communications are located. PostgreSQL 9.6 databases.

Within the implementation strategy, the DRP model is proposed, through a script (Deployment Manager) that allows the deployment of the infrastructure between us-east4 and us-east1 so that if any failure, the same model can continue to be used of DMZ thanks to the fact that the PFSense is found in both regions (Master and Slave), while the HA was raised for the database (covering regional gaps).

In terms of monitoring the application and operation of the different components, Stackdriver is used by means of which there is a faster troubleshooting at the time of a contingency. On the other hand, the appropriate logging level was defined and the stackdriver modules to have on the database servers and others, in order to guarantee the necessary information for the analysis of any anomalous event within the platform.
