Server requirements for self hosting Jamku Portal

[adarshmadrecha]

For very large corporates, we provide option of self-hosting the entire tech stack of Jamku Portal on own server.
This discussion lists down the requirements for the same. Note: This option requires the company to have it's own IT team and is not suited for smaller companies. The pricing for this option starts at 2Lacs per year.

Architecture

Server Requirements

1. Server running Ubuntu 24.04 (LTS Release).
2. RAM: Minimum 2GB (<10 concurrent users). Recommended 4 GB (>20 concurrent users)
3. CPU: Minimum 2 vCPU. Burstable CPU type is preferred (eg: on AWS EC2 - T3a, T3).
4. Storage: Minimum 20GB SSD. Recommended 30GB (access logs storage for longer duration)
5. Networking: Open following ports - ************** (Port Number are not posted here as a security measure). Will need TCP and UDP ports too. Since the web server implements http3 UDP ports are required.
6. One sub domain - Users will be visiting this URL to use the software.
7. SSL Certificate for the subdomains (Wild card SSL certificates are also supported). If the subdomain is accessible from internet, letsencrypt based SSL will be configured by Jamku Support team. If the subdomain is not accessible from internet, your team will have to provide an SSL certificate.

Database Server

We use MongoDB enterprise (version 7.x or 8.x). This is available as service called Atlas from MongoDB Company itself.
Atlas has options to deploy database server on AWS, Azure, Google Cloud.
Minimum M2 Plan. Recommend M5 Plan (Only required for more than 200 PANs, 200 GSTIN, 200 TANs).
Even if you opt for M2 Plan for now, Atlas provides one click upgrade to M5 Plan. Thus, saving cost upfront and scaling when required.
Visit https://www.mongodb.com/pricing for all pricing options.

If your IT team hosts MongoDB themselves, we can connect to the same. It is not compulsory to opt for Atlas.

File Server

Recommended option is S3 for file storage.
You are however not limited to AWS for S3 storage. Any S3 compatible service will work (example: Blackblaze, Cloudian, Google Cloud, and many others)

For a friction free setup, we recommend using AWS S3.
We also have local file storage option, but the scaling and backup will take a beating.
In case of local storage of file, you will be responsible for backup of data.

Expectations from IT team

1. Provisioning the server with above requirement
2. Configuring networking (Port opening and IP Provisioning), including firewall.
3. OS installation and periodic updates. This includes installation of security patches.
4. SSL certificate (See note above)
5. Purchase of MongoDB Atlas subscription
6. S3 Bucket creation and sharing credentials to connect to the bucket.

Setup by Madrecha Solutions team (Team Jamku)

1. Node Installation (v22.x or newer)
2. Web server setup (Caddy)
3. Frontend & Backend setup
4. Database connectivity to the backend

Benefits & Pitfalls of Self-Hosting

Benefits

1. Complete Privacy & Confidentiality of the data
2. No data ever leaves company's network/servers
3. Better pricing for extremely high number of users

Pitfalls of Self-Hosting

1. Complex server setup will require monitoring by Company's IT team.
2. The cost is significantly higher.
3. Initial server setup will take 2-4 days. Hence go-live can take some time.
4. SSL certificates will need to be renewed periodically and re-configured.
5. Additional licensing/billing for database server
6. Manually apply updates. If IT team is not prompt in applying the updates, users will not be able to enjoy the latest features ASAP.
7. IT team has to assume responsibility of Securing the tool from Cyber Attacks. This can be mitigated to a large extend if the tool is not exposed to internet (i.e. Users will be able to use the tool only when on corporate network)
