Server Modules for Containers

Cosemo

Server Module Framework for Containers

Background

When coding for the web there are some questions always emerging when you want to create the backend

• Which programming language and framework should be used?
• How to do login?
• Where should I host the backend?
• Is it possible to get a HA setup cheap, and easy to code?
• Which database should be used?
• How can I scale my file system?
• How do I do backups?
• How many users can I serve easily in the future if the service grow?
• Which security measures should I use?
• Can I have persistent sockets?
• How do I test my code?

Containers

Containers are emerging as a paradigm to how to host backend applications. There is a lot of work put into orchestration of them, and a lot of companies try to switch their old monolithic applications into micro-services. But as a developer or Ops guy I still have many questions which I need answers to.

• Which orchestrator should I use?
• How should I write my interface between services?
• Can I reuse services created by others in my setup?
• What about security between containers?
• Where is the documentation for the services?
• Can I have a system to test external services?
• Loadbalancing build into the orchestrator or create my own?

What if

What if we could have a framework where all these questions didn't need answers? A framework where I can write my code in almost any language I want, document the API in the requests, plugin any service I want from others, only write my code and skip all the bloated lines of code just to manage all?

This is the reason Cosemo was created. It is a framework which tries to minimize the code a backend developer need to write to be able to handle all the stuff you always need to handle.

Framework

So what will Cosemo handle?

• Command based modules with json payload and gRPC as internal transport
• Managing module
• Log module
• A router module which will be frontend into the system. This will be scalable
• A interconnect which will connect all the services with each other and the routers
• Security between all services through the managing module and interconnects
• Swappable user module for handling user info and login
• Streaming endpoints which you can redirect streaming services to
• All connection code for services
• Defining all aspect of a service as json a object

And a lot more.
