New deployment: PSM portal has been selected by SIAAP (Paris area water authority)

January 2022

Fitting the needs for a powerful, flexible, and cost-effective storage solution, the PSM portal is deeply involved in the digital transformation of the public sector.

Our customer: SIAAP, a company which is a major water treatment player in the Ile-de-France area through its Innovation Department, that which to get all the benefits of a Cloud serverless architecture when deploying its solution of wastewater monitoring.

Customer’s requirements: in emergency context of tracking the spread of covid, the aim is to get, as soon as possible, a platform allowing exchange of very large files, which access was restricted to authorized users and allowing the rapid transfer of large volumes of data in complete safety.

The proposed solution by Edifixio: the storage portal PSM. Deployed as part of a new enhanced wastewater monitoring and analysis program put in place by the Innovation Department. PSM is a cloud-native storage portal, based on a serverless architecture. As a result, its deployment is greatly facilitated and can be quickly carried out. It also benefits from all the advantages of this technology, which is deeply involved in the digital transformation of companies.

Speed and agility
The main interest of serverless technology is to save time from imagining a concept to put it into production. Developers no longer have to worry about constraints related to the infrastructure (hardware, servers, networks, …), capacities and resources involved in the implementation. They can totally focus on coding, testing, qualifying, … without wasting time on the infrastructure required for releasing and deploying software.

Developers and IT teams no longer have to worry about anticipating the system's ability to support future load increases. The scalability of the application is provided by the cloud provider (AWS for PSM Portal). This one provides the necessary resources according to the needs of the application in a fully elastic way.

Serverless platforms are more reliable and resilient by nature since they are loosely coupled from infrastructure and its related operating hazards. Developers, released from many constraints, can keep attention on the quality of the code that is being implemented. This results in executions that are generally more reliable, especially since they are based on resources whose capacities are always compliant to the requested load and whose operation is guaranteed.

Reduced costs
With a serverless architecture, the only costs are operating costs. There are no costs related to the acquisition and installation of hardware, neither cost for operating system costs nor for attached licenses, no maintenance and update costs for the OS and the tools being used. These advantages are specific to the cloud, but with serverless architecture, companies also save unused resources (virtual machines that are started but remaining unused (or underused), oversized storage devices, etc.). Serverless is based on a "pay-as-you-go” model for which only the resources (memory, storage, and CPU) being used during the execution of the code are charged). This is the FaaS (Function as a Service) model for which the code is only executed when the events for which it is intended to react are triggered: therefore, you only pay when the event is triggered during the necessary time to carry out the functionality and not beyond.

Edifixio relied on all these concepts to implement the PSM portal from all the necessary AWS modules:
  • S3 bucket (storage)
  • Lambda functions (code execution)
  • DynamoDB (managed DB service)
  • SNS (Simple Notification and Simple Email services)
  • SQS (Single Queue Service)
  • Cognito (provision of identities)

The huge flexibility and agility allowed by the serverless architecture allowed to quickly deploy an application that is fully compliant to the specific needs of the SIAAP Innovation Department and remains able to be easily and quickly enhanced to fit meet future requirements that could be expressed, whether in terms of storage possibilities, costs, performance, or deployment.

With no doubt, all these assets validate the growth forecasts made by Forrester regarding the serverless architecture. According to these forecasts, in 2022, more than 50% of the companies plan to adopt “cloud-native” developments.
