One year after the launch of version 1.0 we announce today the availability of version 3.0 of Intelligent Hybrid Mail.
Our PostGreen cloud now uses this version 3.0.

This is an opportunity for us to review the elements developed this year:

A public roadmap https://roadmap.nirva-software.com presents the work in progress and to come.

We are currently working on improving the support that could be offered directly from the application.
The next step will be to facilitate the integration of Intelligent Hybrid Mail, for example by Document Management software operators who would like to send their mail automatically from our infrastructure. We will tell you more about this later in the year.

In November we added a new feature to the product Intelligent Hybrid Mail.
It's possible now to use data files (CSV files or flat files) to create mailings in the application.
Your data file will contain the address and the application will check the address validity.

There is no mandatory header, no mandatory format.
When we create a service, we will fetch your existing CSV columns to build a correct address.

You can now schedule an appointment with our team using the form below.

We can present here two use case of this channel on the PostGreen cloud.

This channel is used by condominium property managers. In order to save on operating costs, they choose to have all the documents delivered to the caretaker of the building. The latter then deposits the mail in the letterboxes of the addressees. The mails are sorted by name in the parcel.

This channel is also used within companies for which we print their employees' pay slips. We send a parcel with unsealed envelopes. The managers can then add the Ticket Restaurant to the envelopes before distributing them to the employees. Documents are sorted by activity (Management/R&D/Support/Finance...) and by name in the parcels.​

You have created a service to send your invoices using the EMAIL channel.
It is not unlikely that when sending a few hundred emails you will receive errors (full mailbox, incorrect email address...). You will then have to deal with each element.

With Intelligent Hybrid Mail it is possible to configure a fallback channel for your shipments.
For example, when shipments sent by EMAIL channel come back with a specific error code, then the application will send again the documents using the MAIL channel automatically.
The error codes are defined by the system administrator. And then in your Service creation you can activate or not the fallback channel.

Note that this applies to all existing channel types.

First, you have a classic installer. Use it with administrator rights and install the virtual printer on your computer.

Then the idea is extremely simple. You write your letter, or you check a pdf document but instead of printing it on your local printer, you choose to print using our Virtual Printer.

No need to go to the post office, hit CTRL+P, choose our printer and that's it.

At Nirva Software our cloud instances are managed with Docker swarm or Virtual machines on Proxmox.
When you manage dozens of machines you need a to have one entry-point to monitor all the infrastructure.

Monitoring an infrastructure is not magic, you need probes and data.
With our current infrastructure we gather: 

• application logs (apache, tomcat, database, ...) with Logstash 
• host server logs (hard disk, memory, cpu, server login...) with MetricBeats

Our monitoring team use all these metrics to build counters, alerts and visualization graphs. See some practical examples below.

Apache monitoring
Using the apache logs you can extract an approximate origin of the people connecting (or trying to connect) to your solution.
If your apache server handles 80% of its traffic with connections coming from countries where you don't have clients, a simple fail2ban solution will probably be interesting to block this traffic.
The apache server may act as a proxy,  so a DDOS attack will also trigger alert if you monitoring your sever wisely.

e.g.: a test environment accessed mainly from France, United Kingdom and United States. Everything fine.

At a glance we identify which machine is becoming the bottleneck in the system and we can act quickly by adding new host in the network.

Conclusion
Monitoring is very important when setting up a service.
You may have the best software, but if you are not able to monitor it properly, then you will finnaly crash your system.

At NIRVA we have dedicated a team to control all our internal and cloud infrastructures. Every month plans are made to adapt the current monitoring solution.

This is why we decided to focus on setting up dedicated cloud environments for our customers. We take care of the infrastructure by managing the servers, and you take care of developing your business using your dedicated Intelligent Hybrid Mail instance.

On the api web pages you will find three elements : 

• a html documentation
• a swagger documentation
• a json collection for Postman

​Intelligent Hybrid Mail is a full REST JAVA application.
The documentation is dense and it will continue to growth.
Nevertheless, there's no need to be afraid, only three REST calls are necessary to create a delivery:

1. authenticate your user
2. create the job by sending the files
3. create the delivery based on the job

The video below shows you how to do it using PostMan.

And if you have question do not hesitate to contact the support team !

Since September 2019 we have opened our new cloud solution based on Intelligent Hybrid Mail only to a small set of client for testing purposes.
​
We are now proud to announce the official release of the software.
Intelligent PostGreen is now accessible to everyone.

Intelligent Hybrid Mail development continues to add more features...
