Complex Database Replication & Syncronisation

Cancelled

Job Description

We are seeking expressions of interest form very experienced Database Professionals that have real world large scale experience in setting up OSS databases like PostgreSQL, MySQL or MariaSQL for multi-site replication and syncronisation.

We are preparing a Project Proposal for the development of a large Cloud Application built using OSS on the LAMP stack; one of the requirements are that it keeps a replicated copy on local Servers in the case of infrastructure (Net or Power) failure, allowing users to keep working locally, and then when the Cloud is available again, can syncronise changes back to the Cloud (Master).

This is made more complicated by two things:
1. there will be many clients (companies) using it at the same time.
2. some of them may have lost access to the Cloud and be working on local server, updating
3. some may still be on the Cloud, updating

So we have updates on both the Cloud and multiple offline local Servers, however each instance will be a different company, therefore a different logical database, so no conflicted changes will be made on the same logical database.

What we want is to hear form Database Professionals that fully understand this problem AND have solved it before, with details of your past projects and how you tackled it.

The first stage of this project will be to help prepare a Project Proposal to explain the technical approach to solving this problem, the second part will be the proof of concept project, the third will be to implement it for the full project, so its a long term role. Only experienced professionals need apply.

*** DUE TO PAST EXPERIENCES WE ARE ONLY SEEKING APPLICATION FROM DEVELOPERS IN: PHILIPPINES, VIETNAM, INDONESIA, BRAZIL, ARGENTINA and some RUSSIAN STATES and some EASTERN BLOCK COUNTRIES.
