BUSINESS REQUIREMENT

One of the leading news publishers in the Middle East approached us in need of an online classifieds platform to boost their online presence and increase their reach.

• The requirement was to build an online classifieds platform for jobs, properties, autos and other classifieds.
• Filters like location, price, make and model across different verticals for better search must be available
• The admin must be given access to monitor the users and their actions on the platform.
• Subscription system for sellers to place ads in the platform.
• The functionalities must be grouped based on verticals and scale up/down based on requirement.

CHALLENGES

• The platform should be smart about handling peaks in traffic and scale smoothly to prevent site outages/ unnecessary billing costs.

SOLUTIONS

• All the platform functionalities were split based on verticals/sections and implemented as stand alone micro services with Vert.x.
• These micro services were monitored and automatically scaled up/down based on varying user loads across different sections of the site at different times.
• We wanted the search results be available at nanosecond rates and hence utilised DynamoDB for faster and efficient query.
• SQS/SNS were used as persistent communication channels across site modules.
