Since the beginning of the pandemic, Ukraine (like many other countries) has faced an urgent need for a national distance learning platform that did not exist before.
The state government chose the Prozori Solutions to develop the national eLearning platform and mob app: “All-Ukrainian online school” (“Vseukrainska Shkola Online” - VSO).
The platform was created in cooperation with the Ministry of Education and Science of Ukraine, the Ministry of Digital Transformation of Ukraine, The NGO Osvitoria, The Ukrainian Institute of Education Development (UIED) with support of Switzerland within the Swiss-Ukrainian project DECIDE

Fast and transparent deployment, deployment of the system in a short period of time

Creating a service to provide the ability to synchronize data by platforms

Rapid development of “bidding procedures”, easiness of creating new procedures and configuring their timeline

Development of the auctions module with a front-end part, easiness of configuration of new types of auctions

Due to the fact that the system had grown to such an extent that regular deployment could turn into a full-time operation without a guarantee of success.

the absence of versions of the code services and components

components are scattered across many repositories, some of which are used in the procurement system

manual assembly of services, which leads to the additional workload on the DevOps team and an increased probability of human error

violation of encapsulation of services and components, versions of dependencies were defined not by service, and in the course of deployment

There are three main components of the system: the Central Database (CDB), the Auction Module and E-Trading venues. It’s somewhat similar to the stock exchange and brokers. Venues interact with Central Database, while end users are free to choose any Venue they like. They still will be able to view all tenders available in the entire system. Vendors can bid on any tender, regardless of the venue it is announced through. This approach helps prevent one venue growing into an expensive and inefficient monopoly.
The typical e-procurement process will run as follows: the requestor publishes a tender for procurement at any chosen venue. The tender information is made available to all connected Venues via the Central Database. All users can view the tender conditions and may express their interest to participate in the tender

Then, the amendment period begins:

Potential vendors can ask for clarifications regarding the tender or alert the requester of any errors in tender description or unfair conditions. The requestor will answer these questions and amend tender conditions if necessary. Bids aren’t accepted during this period. After the amendment period is over, the requestor can no longer modify the tender and vendors can submit their bid. Bids remain closed and the requestor cannot see company names or price offers at this stage. On the next day after bid submission, the revenue auction starts automatically. participants have three rounds to lower their bids and set the final price. During the auction, participants can see each other’s price offers, but not company names: each vendor is labeled with a number, e.g.: Bidder 1, Bidder 2, etc.
The reverse auction enables government buyers to obtain the lowest price for goods, products or services specified. Once the auction is completed, all bids are open and participant names, proposals and prices revealed, so participants can see competitors’ proposals. The requestor verifies bids starting from the lowest one. If the company that offered the best price meets pre-defined qualifications criteria, it must be selected as winner and the procurement process ends.

Testing

Replacement of the existing database management systems with MongoDB. As a result, fault tolerance was increased in general and the process of synchronization of the sites significantly simplified the process of synchronization of sites with centralized databases.

For serialization / deserialization and access control to non-public data, it was decided to use the Schematics Python library, which is positioned as an ORM without a database layer.

Fault tolerance:The first step was containerization and the transfer of all services under the control of Kubernetes. The next one was the rejection of services in a single copy (each component was developed taking into account the fact that it will have several copies). The third is a guaranteed stateless architecture of all services. Another factor that ensures the stability of the solution is the full automation of deployment. All centralized database components, including infrastructure configuration, are stored in GitLab and delivered to environments using Helm and GitLab CI.
